TY - JOUR. T1 - Expression of Das-1 in primary lung adenocarcinomas represents reactivation of an oncofetal pulmonary antigen. AU - Deshpande, C. G.. AU - Shah, R. N.. AU - Yeldandi, A.. AU - Papreddy, K.. AU - Badve, S.. PY - 2002/12/1. Y1 - 2002/12/1. N2 - Objective: The monoclonal antibody (mAb) designated as mAb Das-1 was generated against a colonic epithelial protein. It reacts with bronchiolar epithelium and submucosal glands and weakly with alveolar lining cells of fetal lung. Adult alveolar epithelium is, however, nonreactive for mAb Das-1. The present study was designed to evaluate the immunoexpression of Das-1 and to correlate it with the histomorphology of primary lung adenocarcinomas and intestinal metaplasia. Methods: Eighty-four cases of primary lung adenocarcinomas were reviewed and categorized according to histologic grade and subtype. Immunohistochemical staining with mAb Das-1 was performed with normal colon as control. Results: Expression of Das-1 in the submucosal bronchial ...
In the present study, we demonstrated PCV and EGFR mutation status as independent prognostic factors in untreated advanced lung adenocarcinoma patients. We also showed that PCV , 2.2 ng/ml was a predictor of a favorable outcome in both advanced lung adenocarcinoma patients with wild-type and mutant EGFR.. Serum CYFRA 21-1 has been reported as a prognostic factor in patients with a variety of cancer types, including resectable NSCLC [39, 40], biliary tract cancer [41], urothelial cancer [42], head and neck cancer [43], esophageal cancer [44], and cervical cancer [45].. A meta-analysis of CYFRA 21-1 as a prognostic indicator in advanced NSCLC patients showed that the PCV may be a reliable prognostic factor [29], however, since non-adenocarcinoma accounted for 65% of the cases and squamous cell carcinoma for 50%, the role of serum CYFRA 21-1 as a prognostic indicator in the lung adenocarcinoma population remained unclear. Moreover, in a study of PCV as a prognostic indicator in advanced NSCLC ...
Licorice and its components have been reported to posses various anti-tumor activities, but its active ingredients and underlying mechanisms are not well understood yet. In the present study, a group of representative licorice-derived compounds that could be detected in rat plasma or urine were screened for anti-tumor activity. Among these compounds, isoangustone A (IAA) was found to promptly Inhibit the viability of SW480 human colorectal adenocarcinoma cells in a time- and concentration-dependent manner. Further analyses indicate that IAA activated caspase-dependent pro-apoptotic signaling and induced significant apoptosis, while had little effect on cell cycle. IAA strongly inhibited Akt phosphorylation within 5 min; however, overexpression of constitutively activated Akt could not rescue IAA-mediated inhibition, indicating that inhibition of Akt was not involved in IAA-induced apoptosis. Further examinations show that IAA induced dissipation of mitochondria membrane potential and release of ...
Previous studies have observed that carboxyl-terminal binding protein 1 (CtBP1) is highly expressed in several malignant tumors, such as breast, glioma and prostate tumors, and it was found to play a role in cancer development (5,6,9,10). However, the expression pattern and biological functions of CtBP1 in lung adenocarcinoma remain largely unknown. The present study aimed to address this by examining the expression patterns of CtBP1 in lung adenocarcinoma tissues, its correlation to clinicopathological features, and its effects on the malignant behavior of lung cancer cells. As such, it represents the first investigation of the clinical significance of CtBP1 expression in lung adenocarcinoma patients. Using IHC, we found that CtBP1 was upregulated in lung adenocarcinoma patients with lymph node metastasis. Moreover, CtBP1 expression was strongly associated with tumor differentiation, size and with poor overall survival of lung adenocarcinoma patients. These data suggest that CtBP1 may act as an ...

Adenocarcinomas metastatic to brain from lung or colon may pose differentiation difficulties. Ultrastructurally, both may have brush borders with rootlets. This study examines the ultrastructural morphology and immunohistochemical expression of villin (associated with rootlets), cytokeratin 7 (present in lung adenocarcinomas), and cytokeratin 20 (present in colon adenocarcinomas) in 19 formalin-fixed sequential surgical biopsies of lung adenocarcinomas metastatic to brain as compared to 13 colonic adenocarcinoma metastases. Of lung tumor metastases, mucinous differentiation with rootlets was most common [6/19(32%)]. All colon tumor metastases were cytokeratin 7(-), 20(+), and profusely villin(+). Well-formed rootlets were seen. All lung metastases were cytokeratin 7(+) and 20(-). 5/6(83%) lung metastases with rootlets were focally villin(+). 12/13(95%) without rootlets were villin(-). Rootlets are extremely common in lung adenocarcinoma metastatic to brain. Villin immunoreactivity closely correlates
Purpose: The microRNA-34b/c (miR-34b/c) is considered a tumor suppressor in different tumor types and a transcriptional target of TP53. The main objectives of this study were to investigate the clinical implications of miR-34b/c methylation in patients with early-stage lung adenocarcinoma and to determine the functional role of miR-34b/c re-expression in lung adenocarcinoma cell lines.. Experimental Design: Aberrant methylation and expression of miR-34b/c were assessed in 15 lung adenocarcinoma cell lines and a cohort of 140 early-stage lung adenocarcinoma. Lung adenocarcinoma cell lines were transfected with miR-34b/c and the effects upon cell proliferation, migration, invasion, and apoptosis were investigated.. Results: Aberrant methylation of miR-34b/c was detected in 6 (40%) of 15 lung adenocarcinoma cell lines and 64 of 140 (46%) primary lung adenocarcinoma. Expression of miR-34b/c was significantly reduced in all methylated cell lines and primary tumors, especially with TP53 mutations. ...

Cisplatin (Csp) is a recurrently used chemotherapeutic drug but its use is inadequate due to undesirable adverse effects. In search of alternative medicine more attention has been given to phytochemicals. Septilin (Spt), a polyherbal drug and its therapeutic potential is huge but there is a scarcity of studies on its cytotoxic potential on cancer cells. The current study was designed to examine the effects of Spt in combination with Csp on human breast adenocarcinoma (MCF-7) and normal human breast epithelial (MCF-10A) cell lines. Cell viability for Spt treated cells was studied using MTT assay. IC50 value of Csp on MCF-7 cells was found to be 10 µg/mL at 24 h. This dose was further used to study the combined effects of Csp with Spt on MCF-7 and MCF-10A cell lines. Maximum cytotoxicity of Spt on MCF-7 cells was observed at Spt 5 µg/mL. The mechanism of Spt induced cytotoxicity was studied using apoptosis assay. Spt did not show any cytotoxic effects on MCF-10 A normal human breast epithelial ...
BACKGROUND/AIM AXL (anexelekto) has been explored as a potential novel therapeutic target for non-small cell lung carcinoma (NSCLC) but its activation status has not been evaluated in NSCLC. PATIENTS AND METHODS We first immunolocalized the phosphorylated form of AXL in 112 lung adenocarcinoma cases and subsequently evaluated the anti-neoplastic effects of monoclonal antibody AXL in two lung adenocarcinoma cell lines, PC9 and A549. RESULTS Phospho-AXL immunoreactivity was detected in 59.8% of adenocarcinoma cases examined and tended correlate significantly with larger tumor size (p=0.08) and with overall survival of the patients (p=0.041). Results of in vitro analysis revealed that the monoclonal antibody to AXL significantly inhibited cell proliferation of PC9 and A549, lung adenocarcinoma cell lines, which was caused by an inhibition of extracellular signal-regulated kinase (ERK) activation. CONCLUSION AXL-targeted therapy, possibly through inhibiting ERK activation of carcinoma cells, could
The aim of the present study was to investigate the association between serum levels of matrix metalloproteinase 11 (MMP-11) and responses to front-line chemotherapy and prognosis in advanced unresectable gastric adenocarcinoma. Clinical data concerning 86 patients with advanced gastric adenocarcinoma (stages III c to IV), treated in Beijing Chao-Yang Hospital from 2005 to 2009, were reviewed retrospectively. Adenocarcinoma was confirmed by pathology and patients received 5-fluorouracil-based front-line combination chemotherapy with third generation chemotherapeutic agents including paclitaxel, docetaxel and oxaliplatin. The regimen was repeated every two to three weeks, and the first evaluation was carried out after three cycles. The median cycle of chemotherapy was 6 (ranging from three to twelve cycles). Serum MMP-11 protein from the 86 patients was examined using enzyme-linked-immunosorbent-assay (ELISA) prior to chemotherapy and after three cycles of chemotherapy. Serum samples from healthy

Metastatic adenocarcinoma from an unknown primary site is a common clinical problem. Determining the cytokeratin (CK) 7/CK20 pattern of tumors is one of the most helpful procedures for this purpose since the CK7-/CK20+ pattern is typical of colorectal adenocarcinomas. CDX2, a critical nuclear transcription factor for intestinal development, is expressed in intestinal epithelium and adenocarcinomas. In the present study, we compared the sensitivity and specificity of CDX2 expression and the CK7-/CK20+ phenotype in differentiating colorectal adenocarcinomas from pancreatic and gastric adenocarcinomas. CK7/CK20 staining pattern and CDX2 expression were evaluated in 118 cases of colorectal, 59 cases of gastric, and 32 cases of pancreatic adenocarcinomas. The sensitivity, specificity, and positive and negative predictive values of the CK7-/CK20+ phenotype and of CDX2 expression were analyzed. The CK7-/CK20+ immunophenotype was expressed by 75 of 118 (64%) colorectal and 3 of 59 (5%) gastric tumors and was
p21WAF1/CIP1 protein is a cyclin-dependent kinase inhibitor, discovered to be a downstream effector of p53-dependent cell cycle regulation. In order to elucidate the significance of p21 expression in lung adenocarcinomas, we performed immunohistochemical analysis of p21, p53 and Ki-67 expression in surgically resected lung adenocarcinomas. In non-neoplastic tissue, a few bronchial and bronchiolar suprabasal and ciliated cells, and a few type II alveolar cells and alveolar macrophages in the peripheral lung, were p21 positive, but the positive rate in normal lung tissue was very low (,1%). All 91 lung adenocarcinomas examined showed p21 immunoreactivity: 39 cases (42.9%) and 52 cases (57.1%) showed high and low p21 expression levels, respectively. There was no significant correlation between p21 expression and p53 expression, the loss of heterozygosity status of the p53 gene, histological grade determined by the predominant histology, lymph node metastasis, pathological stage, tumor size, smoking ...

MUC1 protein is highly expressed in lung cancer. The cytoplasmic domain of MUC1 (MUC1-CD) induces tumorigenesis and resistance to DNA-damaging agents. We characterized MUC1-CD-induced transcriptional changes and examined their significance in lung cancer patients. Using DNA microarrays, we identified 254 genes that were differentially expressed in cell lines transformed by MUC1-CD compared to control cell lines. We then examined expression of these genes in 441 lung adenocarcinomas from a publicly available database. We employed statistical analyses independent of clinical outcomes, including hierarchical clustering, Students t-tests and receiver operating characteristic (ROC) analysis, to select a seven-gene MUC1-associated proliferation signature (MAPS). We demonstrated the prognostic value of MAPS in this database using Kaplan-Meier survival analysis, log-rank tests and Cox models. The MAPS was further validated for prognostic significance in 84 lung adenocarcinoma patients from an independent
BACKGROUND. The decline of gastric adenocarcinoma in the U.

Non-small cell lung cancer (NSCLC) includes lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC). MicroRNA (miRNA) plays an important role in the regulation of post-transcriptional gene expression in animals and plants, especially in lung adenocarcinoma. MiR-1307-5p is an miRNA with significant differences screened by the second generation of high-throughput sequencing in the early stage of our research group. In the current study, a series of in vitro and in vivo experiments were carried out. MiR-1307-5p mimic, miR-1307-5p inhibitor, and NC were transfected into A549 and H1299 lung adenocarcinoma cells. The correlation between miR-1307-5p and clinicopathological features in pathological samples was analyzed using a lung adenocarcinoma tissue microarray, and miR-1307-5p expression was detected by qPCR. CCK-8, EdU, colony formation, scratch test, and Transwell assays were used to observe cell proliferation and migration. Double luciferase assay, western blot, qPCR, and immunohistochemistry
Adenocarcinoma[1] (/ˌædᵻnoʊkɑːrsᵻˈnoʊmə/; plural adenocarcinomas oradenocarcinomata /ˌædᵻnoʊkɑːrsᵻˈnoʊmᵻtə/) is a type of cancerous tumor that can occur in several parts of the body. It is defined as neoplasia of epithelial tissue that has glandularorigin, glandular characteristics, or both. Adenocarcinomas are part of the larger grouping ofcarcinomas, but are also sometimes called by more precise terms omitting the word, where these exist. Thus invasive ductal carcinoma, the most common form of breast cancer, is adenocarcinoma but does not use the term in its name-however, esophageal adenocarcinoma does to distinguish it from the other common type of esophageal cancer, esophageal squamous cell carcinoma. Several of the most common forms of cancer are adenocarcinomas, and the various sorts of adenocarcinoma vary greatly in all their aspects, so that few useful generalizations can be made about them. ...

Introduction: Lung adenocarcinoma has a complex variety of different hystopathologic subtypes with distinct epidemiology, pathology and prognosis. Pulmonary adenocarcinoma with enteric differentiation is a rare variant defined as a tumor with more than 50% of colorrectal-like components, immunohistochemistry (IHC) positive for at least one marker of enteric differentiation (CK20, CDX-2 or MUC2) and no evidence of other malignancies. Case Series: Patients were identified in a review of a set of adenocarcinomas, apparently originated in colon, but posteriorly accessed as lung adenocarcinomas. Median age was 57.6 years, were all Caucasian subjects and presented with metastatic disease. The median size were 6.3 cm at the time of diagnosis and all had spiculated shape forms at CT scans. Microscopic description revealed a lepidic (mucinous) adenocarcinoma in all five cases. Immunohistochemistry were positive for CK20 or CDX-2 in all these cases and was negative for CK7 in one patient. Conclusion: The use of

Several SOX genes are involved in lung development and may have functional roles within the lung. SOX9 (a transcription factor) has been shown to be involved in several types of cancer. In this lab-based study, SOX9 expression was investigated in 29 lung adenocarcinoma and 28 normal lung samples using silico data mining, quantitative reverse transcription-PCR and immunohistochemistry.. SOX9 was upregulated at both the mRNA and protein level in the majority of lung adenocarcinomas compared with normal tissue. In addition, recurrent lung adenocarcinoma tissue showed significantly higher SOX9 expression than that of a primary lesion. RNA interference technique and microarray gene expression further demonstrated that knockdown of SOX9 inhibited cell growth, downregulated CDK4 and upregulated p21. These are all important cell cycle regulators and their expression could mediate SOX9-related alteration in cancer cell growth.. SOX9 may be an important biomarker in lung adenocarcinoma which could aid in ...
Despite advances in surgery, radiotherapy, and chemotherapy, pancreatic adenocarcinoma often progresses rapidly and causes death. The physical decline of these patients is expected to impact their quality of life (QoL). Therefore, in addition to objective measures of effectiveness, the evaluation of health-related QoL should be considered a matter of major concern when assessing therapy outcomes. Observational, prospective, multicenter study including patients with metastatic pancreatic adenocarcinoma who started first-line chemotherapy in 12 Spanish centers. Treatment and clinical characteristics were recorded at baseline. Patients health-related quality of life, ECOG, and Karnofsky index were measured at baseline, at Days 15 and 30, and every four weeks up to 6 months of chemotherapy. Health-related quality of life was measured using the EORTC-QLQ-C30 and EQ-5D questionnaires. Other endpoints included overall survival and progression-free survival. The study sample included 116 patients (median age
Despite encouraging clinical results with sorafenib monotherapy in patients with KRAS-mutant non-small-cell lung cancer (NSCLC), the overall survival benefit of this drug is limited by the inevitable development of acquired resistance. The exact mechanism underlying acquired sorafenib resistance in KRAS-mutant NSCLC is unclear. In this study, the mechanism of acquired sorafenib resistance was explored using a biologically relevant xenograft model, which was established by using the A549 human lung adenocarcinoma cell line and an in vivo-derived, sorafenib-resistant A549 subline (A549/SRFres). Results from the initial study demonstrated that sorafenib treatment significantly decreased E-cadherin (P , 0.05) levels but significantly increased matrix metallopeptidase 9 (MMP9) levels (P , 0.01) in A549/SRFres tumors, whereas expression levels of phospho-protein kinase B (AKT), phospho-focal adhesion kinase (FAK), and phospho-Src were elevated in sorafenib-treated A549 and A549/SRFres tumors. We next ...
Metastatic lung cancer is common in lung adenocarcinoma patients, but the molecular mechanisms of metastasis remain incompletely resolved. MicroRNA (miR) regulate gene expression and contribute to cancer development and progression. This report identifies miR-576-3p and its mechanism of action in lung cancer progression. miR-576-3p was determined to be significantly decreased in clinical specimens of late-stage lung adenocarcinoma. Overexpression of miR-576-3p in lung adenocarcinoma cells decreased mesenchymal marker expression and inhibited migration and invasion. Inhibition of miR-576-3p in non-malignant lung epithelial cells increased migration and invasion as well as mesenchymal markers. Serum/glucocorticoid regulated kinase 1 (SGK1) was a direct target of miR-576-3p, and modulation of miR-576-3p levels led to alterations in SGK1 protein and mRNA as well as changes in activation of its downstream target linked to metastasis, N-myc downstream regulated 1 (NDRG1). Loss of the ability of ...
Background: Tumor budding has recently been reported as an independent adverse prognostic factor for colorectal adenocarcinomas and other types of carcinoma in the digestive tract. This study aimed to evaluate the prognostic value of tumor budding in patients with early-stage cervical adenocarcinomas and any associations with other clinical and pathological features. Methods: Histological slides of patients with early-stage (IB-IIA) usual-type endocervical adenocarcinoma who underwent radical hysterectomy and pelvic lymph node dissection, without preoperative chemotherapy, between January 2006 and December 2012 were reviewed. Tumor budding was evaluated in routinely-stained sections and defined as detached single cells or clusters of fewer than 5 cells in a tumor invasive front and was stratified based on the number of bud counts in 10-high-power fields as low (follow-up outcomes were assessed. Results: Of 129 patients, a high tumor bud count was observed in 15 (11.6%), positively associated with
The correlation and overlaps between PD-L1 expression and classical genomic aberrations in Chinese lung adenocarcinoma patients: a single center case series
Background: A steep increase in the incidence of esophageal adenocarcinoma has been observed between 1973 and 2001, but recent trends have not been reported. Our aim was to examine recent trends in esophageal adenocarcinoma incidence.. Methods: We used the Surveillance Epidemiology and End Results database of the National Cancer Institute to identify all patients who were diagnosed with esophageal adenocarcinoma between 1973 and 2006. Incidence trends were analyzed for esophageal adenocarcinoma overall and by stage using joinpoint regression.. Results: Overall esophageal adenocarcinoma incidence increased from 3.6 per million in 1973 to 25.6 per million in 2006. Incidence trend analysis, however, suggests that the increase has slowed, from an 8.2% annual increase prior to 1996 to 1.3% increase in subsequent years (P = 0.03). Stage-specific trend analyses suggest that the change in overall esophageal adenocarcinoma incidence largely reflects a plateau in the incidence of early stage disease. Its ...
A macrophage-mediated antibody-dependent cellular cytotoxic reaction has been described in a syngeneic murine mammary adenocarcinoma model. The antibody appears to be present in two forms, one apparently complexed with antigen and the other identified as 7S immunoglobulin on Sephadex G-200 and as the IgG2a subclass by blocking of Fc receptors on the macrophages. This antibody is first detected in mice with regressing tumors. Tumor cells from immune mice appear to be coated with this antibody, as they are sensitive to the effects of normal macrophages in vitro, whereas tumor cells from immunologically compromised mice are not. Thus, a macrophage-dependent reaction probably is relevant in the in situ immune defenses against this tumor.. ...
We report an SB insertional mutagenesis screen to identify loci that cooperate with oncogenic Kras to drive pancreatic adenocarcinoma in the mouse. SB-driven pancreatic adenocarcinomas show all stages of mPanIN that develop into early noninvasive adenocarcinoma and finally, invasive, highly metastatic adenocarcinoma. Importantly, these tumors also have a high desmoplastic component, a predominant histopathic feature of human pancreatic cancer. The T2Onc3 transposon proved to be more potent than T2Onc2 in inducing metastatic tumors. The exact mechanism for the difference between the two transposons in driving pancreatic cancer is unknown. One possibility is that the location of the transposon concatemer donor influences the development of the tumor. The T2Onc3 donor resides on chromosome 9, and pancreatic cancer genes in close proximity may be frequently mutated in these tumors because of local hopping.. Both T2Onc2 and T2Onc3 cohorts exhibited considerably higher numbers of nonredundant ...
The p63 gene is a recently discovered member of the p53 family located at chromosome 3q27Many studies have reported that overexpression of p63 can mimic p53 activities by binding DNA, activating transcription, and inducing apoptosis.. Various studies proved p63 as a marker of basal cells in normal salivary glands, breast, prostate, respiratory and squamous epithelia, and of tumor cells from various malignancies. Still, p63 has been the subject of relatively few studies in lung adenocarcinoma, and breast carcinoma, and no study has described the correlation of p63 with pancreatic ductal adenocarcinoma.. In the current study, we aim to evaluate the prognostic value of the expression of p63 in the lung adenocarcinoma, breast adenocarcinoma, and pancreatic ductal adenocarcinoma. We will achieve this aim by collecting clinical data retrospectively from the patients medical records as well as assessing the histological sections and performing immunohistochemical staining for p63. ...

Nectin-like molecule-5 (Necl-5) is an immunoglobulin (Ig)-like molecule that is up-regulated in many types of cancer cells. It was shown experimentally that Necl-5 enhances cell migration, proliferation, and metastasis, but its clinical significance has not been documented. The aim of this study was to observe the expression of Necl-5 in surgically resected primary lung adenocarcinomas and to investigate its clinical significance. A total of 63 surgically resected primary pulmonary adenocarcinoma tissues were investigated by immunohistochemistry for the expression of Necl-5. The relationship between expression of Necl-5 and clinicopathological features was analyzed, and the influence of Necl-5 expression on outcomes in these patients was assessed. A strong expression of Necl-5 by cancer cells was observed in 43 of the 63 tumors. The overexpression of Necl-5 by cancer cells was significantly associated with lymph node metastasis (P = 0.0398), TNM staging (P = 0.0367), and the bronchioloalveolar ...

Identification of the primary sites of metastatic adenocarcinomas is a diagnostic problem, particularly in cases of occult primary neoplasms. We studied the ultrastructural morphology of 16 metastatic adenocarcinomas that presented as effusions to establish organ-specific features that would characterize adenocarcinomas from various sites. The nine cases in which the site of the primary carcinoma was known included seven derived from the breast, one from the ovary and one from the colon. The primary site was unknown in seven cases at the time of presentation. After investigations, the primary site became known in five cases (lung, colon and appendix, one case each, and the ovary in two cases). Ultrastructurally diagnostic features could be detected in gastrointestinal, ovarian, bronchioloalveolar-cell and breast carcinomas. In gastrointestinal carcinomas, the presence of short microvilli with long rootlets was specific for the group. The lamellar inclusions of type II pneumocytes were diagnostic ...
PURPOSE: To better understand the complete genomic architecture of lung adenocarcinoma. EXPERIMENTAL DESIGN: We used array experiments to determine copy number variations and sequenced the complete exomes of the 247 lung adenocarcinoma tumor samples along with matched normal cells obtained from the same patients. Fully annotated clinical data were also available, providing an unprecedented opportunity to assess the impact of genomic alterations on clinical outcomes. RESULTS: We discovered that genomic alternations in the RB pathway are associated with significantly shorter disease-free survival in early-stage lung adenocarcinoma patients. This association was also observed in our independent validation cohort. The current treatment guidelines for early-stage lung adenocarcinoma patients recommend follow-up without adjuvant therapy after complete resection, except for high-risk patients. However, our findings raise the interesting possibility that additional clinical interventions might provide medical

Introduction: Over the past decade potatoes with purple- and red-fleshed color rich in antioxidants (phenolic compounds - phenolic acids, anthocyanins etc.) have attracted the attention of consumers and scientists due to their appearance, flavour and biological properties. It is assumed that they have the potential to be an important source of biologically active compounds in the human nutrition and beneficial for human health. The aim of this study was to investigate whether potato tubers with coloured flesh might suppress human gastric adenocarcinoma cells (AGS cells) proliferation and viability. Object and methods: The field experiment was conducted in 2017 and 2018 on farm in Širvintos district (Lithuania). The study was implemented with 5 potato cultivars (Solanum tuberosum L) with different coloured flesh. In the conventional farming system the mix of universal complex fertilizers (Blaukorn Novatec N14P7K17) was used during potato crops vegetative period by inserting the 112 kg ha-1 ...
Mechanisms behind the strong associations of esophageal adenocarcinoma risk with gastroesophageal reflux (GOR) and body mass remain to be defined. In a nationwide population-based case-control study, we examined associations of polymorphisms in the DNA repair genes XPD, XPC, XRCC1 and XRCC3 with risk of esophageal adenocarcinoma, squamous-cell carcinoma (SCC) and gastric cardia adenocarcinoma, and paid special attention to possible interactions with symptomatic reflux or body mass. We collected blood samples from 96, 81 and 126 interviewed incident cases of esophageal adenocarcinoma, esophageal SCC and gastric cardia adenocarcinoma, respectively, and 472 randomly selected controls, frequency-matched with regard to age and sex. DNA was extracted and polymorphisms in XPD codon 751 (Lys→Gln), codon 312 (Asp→Asn), C insertion in intron 10 of XPD, XPC codon 939 (Lys→Gln), XRCC1 codon 399 (Arg→Gln) and XRCC3 codon 241 (Thr→Met) were examined using PCR-RFLP. Odds ratios (ORs) derived from ...

Results 253 incident EAC, 191 gastric cardia adenocarcinomas and 125 gastric non-cardia adenocarcinomas accrued to the cohort. Overall obesity (BMI) was positively associated with EAC and gastric cardia adenocarcinoma risk (highest (≥35 kg/m2) vs referent (18.5-,25 kg/m2); HR 2.11, 95% CI 1.09 to 4.09 and HR 3.67, 95% CI 2.00 to 6.71, respectively). Waist circumference was also positively associated with EAC and gastric cardia adenocarcinoma risk (highest vs referent; HR 2.01, 95% CI 1.35 to 3.00 and HR 2.22, 95% CI 1.43 to 3.47, respectively), whereas waist-to-hip ratio (WHR) was positively associated with EAC risk only (highest vs referent; HR 1.81, 95% CI 1.24 to 2.64) and persisted in patients with normal BMI (18.5-,25 kg/m2). Mutual adjustment of WHR and BMI attenuated both, but did not eliminate the positive associations for either with risk of EAC. In contrast, the majority of the anthropometric variables were not associated with adenocarcinomas of the gastric non-cardia. ...

Background The prognosis of patients with gastroesophageal adenocarcinoma is poor. There is conflicting evidence regarding effects of preoperative chemotherapy on survival and other outcomes. Methods We conducted a meta-analysis with aggregate and individual patient data (IPD) to assess the effect of preoperative chemotherapy for gastroesophageal adenocarcinoma on survival and other outcomes. Two independent reviewers identified eligible randomised controlled trials (RCTs) comparing chemotherapy+/-radiotherapy followed by surgery with surgery alone for gastroesophageal adenocarcinoma. IPD was solicited from all trials. Meta-analyses were performed using the two stage method. Results We identified 14 RCTs (2422 patients). For eight RCTs (1049 patients; 43.3%) we obtained IPD. Preoperative chemotherapy was associated with longer overall survival (hazard ratio [HR] 0.81; 95% confidence interval [CI] 0.73-0.89; p < 0.0001). There were larger treatment effects in tumours of the gastroesophageal ...
BACKGROUND: Obesity is associated with an increased incidence of oesophageal and oesophagogastric junction adenocarcinoma, in particular Siewert types I and II. This study compared abdominal fat composition in patients with oesophageal/junctional adenocarcinoma with that in patients with oesophageal squamous cell carcinoma and gastric adenocarcinoma, and in controls. METHOD: In total, 194 patients (110 with oesophageal/junctional adenocarcinoma, 38 with gastric adenocarcinoma and 46 with oesophageal squamous cell carcinoma) and 90 matched control subjects were recruited. The abdominal fat area was assessed using computed tomography (CT), and the total fat area (TFA), visceral fat area (VFA) and subcutaneous fat area (SFA) were calculated. RESULTS: Patients with oesophageal/junctional adenocarcinoma had significantly higher TFA and VFA values compared with controls (both P , 0.001), patients with gastric adenocarcinoma (P = 0.013 and P = 0.006 respectively) and patients with oesophageal squamous ...

Proximal oesophageal cancers are predominantly squamous cell cancer (SCC), with adenocarcinoma constituting approximately 10% of the cases.1 An inlet patch is an area of heterotopic gastric mucosa found in the proximal oesophagus in up to 10% of the population, and adenocarcinoma can develop from this patch, although rarely.2 3 Adenocarcinoma is not as sensitive to radiation as SCC, but surgery for this case would have required resection of the larynx, pharynx and oesophagus, and in combination with locally advanced disease, these considerations underpinned a management decision to treat with radical chemoradiation.. The likely causation of localised metastatic tumour development in this case was malignant cell capture on the PEG bolster when drawn through the obstructing tumour site, with implantation in the stomach wall, and subsequent external progression. A meta-analysis reports the overall rate of PEG site metastasis from upper aerodigestive tract cancers as approximately 0.5%, with 74 ...

Pancreatic ductal adenocarcinoma (PDAC) is usually incurable. Contrary to genetic mechanisms involved in PDAC pathogenesis, epigenetic alterations are ill defined. Here, we determine the contribution of epigenetically silenced genes to the development of PDAC. We analyzed enriched, highly methylated DNAs from PDACs, chronic pancreatitis (CP) and normal tissues using CpG island microarrays and identified WNK2 as a prominent candidate tumor suppressor gene being downregulated early in PDAC development. WNK2 was further investigated in tissue microarrays, methylation analysis of early pancreatic intraepithelial neoplasia (PanIN), mouse models for PDAC and pancreatitis, re-expression studies after demethylation, and cell growth assays using WNK2 overexpression. Demethylation assays confirmed the link between methylation and expression. WNK2 hypermethylation was higher in tumor than in surrounding inflamed tissues and was observed in PanIN lesions as well as in a PDAC mouse model. WNK2 mRNA and protein

N2 - We investigated the effects of a sublethal concentration of H 2O2 on cancer cells by using sublines derived from human lung adenocarcinoma cell line A549 cells exposed to 200 μM H 2O2. These sublines (AST cells) showed an elongated morphology distinct from the rounded morphology of A549 cells. Notably, AST cells demonstrated telomere shortening despite displaying telomerase activity and expressing human telomerase reverse transcriptase (hTERT). This functional impairment of telomerase occurred due to perturbed subcellular localization of hTERT in AST cells. Endogenous as well as ectopically expressed hTERT was localized in the nuclei of ...
Bone is the most common site of metastasis for breast cancer, however the reasons for this remain unclear. We hypothesise that under certain conditions mammary cells possess osteomimetic capabilities that may allow them to adapt to, and flourish within, the bone microenvironment. Mammary cells are known to calcify within breast tissue and we have recently reported a novel in vitro model of mammary mineralization using murine mammary adenocarcinoma 4T1 cells. In this study, the osteomimetic properties of the mammary adenocarcinoma cell line and the conditions required to induce mineralization were characterized extensively. It was found that exogenous organic phosphate and inorganic phosphate induce mineralization in a dose dependent manner in 4T1 cells. Ascorbic acid and dexamethasone alone have no effect. 4T1 cells also show enhanced mineralization in response to bone morphogenetic protein 2 in the presence of phosphate supplemented media. The expression of several bone matrix proteins were monitored

All tumors exhibited DNA copy number changes, with a total of 139 changes detected (range, 11-24 per tumor; mean = 17), indicating numerous and widespread alterations within these cancers. Gains (65%) in DNA copy number were more frequent than losses (35%). Our most striking finding was gain (all eight cases) or high-level amplification (four cases) in 20q, with a ...
Background: Metastatic pancreatic adenocarcinoma has a short median overall survival (OS) of 5-6 months. However, a subgroup of patients survives more than 1 year. We analyzed the survival outcomes of this subgroup and evaluated clinical and pathological factors that might affect survival durations. Methods: We identified 20 patients with metastatic or recurrent pancreatic adenocarcinoma who received single-agent gemcitabine and had an OS longer than 1 year. Baseline data available after the diagnosis of metastatic or recurrent disease was categorized as: 1) clinical/demographic data (age, gender, ECOG PS, number and location of metastatic sites); 2) Laboratory data (Hematocrit, hemoglobin, glucose, LDH, renal and liver function and CA19-9); 3) Pathologic data (margins, nodal status and grade); 4) Outcomes data (OS, Time to Treatment Failure (TTF), and 2 year-OS). The lowest CA19-9 levels during treatment with gemcitabine were also recorded. We performed a univariate analysis with OS as the ...

For the adenocarcinomas, statistical analysis demonstrated that high levels of expression of fms-complementary mRNA correlated strongly with ...
Primary pulmonary mucinous adenocarcinoma (PPMA) is an uncommon subtype of lung adenocarcinoma. The present study attempted to clarify the diagnosis, clinicopathological characteristics, and pathologic significance of epithelial growth factor receptor (EGFR) and Kirsten rat sarcoma viral oncogene (KRAS) mutations and the prognosis of PPMA. A total of 29 patients with PPMA from among 1,469 surgically resected patients with lung adenocarcinoma were enrolled. All of the tumours expressed CK7 and 5 cases exhibited co‑expression with CK20. A total of 8 cases expressed EGFR, 14 cases expressed P53 and 2 cases expressed CEA. The majority of mucinous adenocarcinomas expressed thyroid transcription factor 1, Napsin A, Villin and Cam5.2 proteins. KRAS mutations were observed in 62% of patients and were more prevalent in the lower lung lobe and in patients with invasive mucinous adenocarcinoma. A total of 2 cases exhibited an EGFR mutation, and the co‑mutation of KRAS and EGFR was only detected in 1 ...
The present invention includes a method of utilizing four peptide hormones to inhibit the growth of cancer(s). A dramatic decrease in the number of human pancreatic adenocarcinoma cells (i.e., the type of cancer with the highest mortality, with patients only surviving four months) was observed responsive to treatment. The application of the invention would be to utilize one or more of these peptide hormones alone and/or in combination to treat cancer. The ability of these peptide hormones to decrease the number of adenocarcinoma cells has implications for adenocarcinomas at other sites in the body with the majority of cancers of the breast, colon and prostate also being adenocarcinomas. Adenocarcinomas also occur in the lung and other tissues. Treatment of a wide variety of cancers in addition to adenocarcinomas is anticipated by the present invention.

Although hydroxyurea is one of the most widely used drugs in treating breast cancer, the use of it leads to some side effects. Hence, in order to reduce complications of treatment and increase its efficiency, drug delivery has been attracted more attention. Present study included three stages. The first stage was involved in the synthesis of nanoparticles-loaded hydroxyurea that its characteristics were evaluated by using scanning electron microscopy and Zetasizer system. In the second stage, cultured MCF-7 cells were undergone treatments by hydroxyurea and Nanoparticles-loaded hydroxyurea in various concentrations. In the third stage, the MCF-7 was treated by IC50 of hydroxyurea and nanoparticles-loaded hydroxyurea which are in combination with radiation and hyperthermia. Afterward, the viable of cell, apoptosis, and levels of caspase-8 and-9 proteins were assessed. The average size and the potential surface of nanoparticles and nanoparticles-loaded hydroxyurea were 26 nm, 48 nm, 3.86 mV, and -29.3 mV

The differentiation between malignant mesothelioma and adenocarcinoma based on morphology alone can be a diagnostic challenge. The majority of the available antibodies recognize molecules expressed by adenocarcinoma whereas to the authors knowledge specific markers for mesothelial cells are lacking. Calretinin, a calcium-binding protein, has been reported to be a selective marker for mesothelioma and largely is absent from adenocarcinoma on histologic material. The results with cytologic preparations have been inconsistent. METHODS. To evaluate the specificity of calretinin in differentiating mesothelioma from adenocarcinoma in cytologic preparations, 21 ...

Meaning of nonbronchioalveolar adenocarcinoma medical term. What does nonbronchioalveolar adenocarcinoma mean?
Emerging evidence supports the idea that a dysfunction in cell metabolism could sustain a resistant phenotype in cancer cells. As the success of chemotherapeutic agents is often questioned by the occurrence of multidrug resistance (MDR), a multiple cross-resistance towards different anti-cancer drugs represent a major obstacle to cancer treatment. The present study has clarified the involvement of the carbon metabolites in a more aggressive tumor colon adenocarcinoma phenotype and in a chemoresistant mesothelioma, and the role of pyruvate treatment in the reversion of the potentially related resistance. For the first time, we have shown that human colon adenocarcinoma cells (HT29) and its chemoresistant counterpart (HT29-dx) displayed different carbon metabolism: HT29-dx cells had a higher glucose consumption compared to HT29 cells, whereas human malignant mesothelioma (HMM) cells showed a lower glucose consumption compared to HT29 cells, accompanied by a lower pyruvate production and, ...
Histone deacetylases (HDACs) have been associated with malignant tumor development and progression in humans. HDAC inhibitors (HDACIs) are currently being explored as anti-cancer agents in clinical trials. The present study aimed to evaluate the clinical significance of HDAC-1, −2, −4 and −6 protein expression in pancreatic adenocarcinoma. HDAC-1, −2, −4 and −6 protein expression was assessed immunohistochemically on 70 pancreatic adenocarcinoma tissue specimens and was statistically analyzed with clinicopathological characteristics and patients survival. Enhanced HDAC-1 expression was significantly associated with increased tumor proliferative capacity (p = 0.0238) and borderline with the absence of lymph node metastases (p = 0.0632). Elevated HDAC-4 expression was significantly associated with the absence of organ metastases (p = 0.0453) and borderline with the absence of lymph node metastases (p = 0.0571) and tumor proliferative capacity (p = 0.0576). Enhanced HDAC-6 expression was

BEVILACQUA, Roberta A.U.; CORVELLO, Cassandra M.; DUARTE, Ana Paula and SIMPSON, Andrew J.G.. Detection of microsatellite instability but not truncating APC mutations in gastric adenocarcinomas in Brazilian patients. Genet. Mol. Biol. [online]. 2000, vol.23, n.2, pp.255-259. ISSN 1415-4757. https://doi.org/10.1590/S1415-47572000000200001.. A crucial role for the adenomatous polyposis colonic (APC) gene in colorectal carcinogenesis has been conclusively established, but, the role of APC in gastric tumors remains controversial. APC mutations have been detected at a relatively high frequency in gastric tumors of Japanese patients, yet such mutations have been reported to be extremely rare in British patients and patients from north-central-Italy. We here report the analysis of 40 primary sporadic gastric adenocarcinomas and 35 primary sporadic colon adenocarcinomas (from patients resident in São Paulo, Brazil), for mutations in the APC gene between codons 686 and 1693 using the protein truncation ...
Colorectal epithelium is composed of absorptive, mucous and endocrine cells, all of which are considered to arise from a common stem cell located in the crypt base. However, the factors controlling the commitment to differentiate are poorly understood. This is partly due to the lack of in vitro model systems for the study of differentiation in colorectal epithelium. The HRA-19 cell line, established from a human rectal adenocarcinoma, has been shown to have multipotential characteristics with cloned HRA-19 cells able to differentiate into absorptive, mucous and endocrine cells when grown as xenografts. The lack of such differentiated cells in HRA-19 monolayers in vitro suggests that differentiation is controlled by extracellular matrix, stromal cells and/or soluble factors. Such observations show that differentiation in HRA-19 cells can be controlled by extrinsic factors and therefore provide a model system for studying control of differentiation in colorectal epithelium. Unfortunately, the ...
AZD9291 is a novel, irreversible epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), which is administered orally. It has been proven effective in non-small cell lung cancer (NSCLC) patients, with both EGFR-sensitizing and EGFR T790M mutations in preclinical models. However, the potential therapeutic effects of AZD9291 combined with other modalities, including ionizing radiation, are not well understood. The presence of AZD9291 significantly increases the cell-killing effects of radiation in PC-9-IR cells with a secondary EGFR mutation (T790M), which was developed from NSCLC PC-9 cells (human lung adenocarcinoma cell with EGFR 19 exon 15 bp deletion) after chronic exposure to increasing doses of gefitinib, and in H1975 cells (human lung adenocarcinoma cell with EGFR exon 20 T790M mutation de novo), but not in PC-9 cells or in H460 cells (human lung adenocarcinoma cell with wild-type EGFR ...
Although primary duodenal adenocarcinoma (DA) is a rare malignancy representing ~ 0.5% of all gastrointestinal cancers, the incidence of DA is more frequent in Lynch syndrome. Because of its rarity, treatment strategies or optimal chemotherapeutic regimens have not been clearly defined for advanced DA. A 72-year-old woman with Lynch syndrome visited our hospital with a right upper abdominal pain. Computed tomography (CT) showed wall thickness with enhancement in the second portion of the duodenum and adjacent abdominal wall, which suggested direct tumor invasion to the abdominal wall. Upper gastrointestinal endoscopy (UGE) showed a large ulcerative tumor in the second portion of the duodenum, and histological analysis revealed a poorly differentiated adenocarcinoma. A cT4N0M0, cStage IIB (Union for International Control Cancer TNM staging) DA was diagnosed. After three courses of chemotherapy with S-1 and oxaliplatin (SOX), follow-up CT and UGE showed shrinkage of the duodenal tumor. Therefore, the

AU - De Andrade, Mariza. AU - Boardman, Lisa Allyn. AU - Petersen, Gloria M. PY - 2008/6/15. Y1 - 2008/6/15. N2 - Base excision repair and nucleotide excision repair are vital responses to multiple types of DNA damage, including damage from tobacco exposure. Single-nucleotide polymorphisms (SNP)in these pathways may affect DNA repair capacity and therefore influence risk for cancer development. We performed a clinic-based, case-control study comprising 481 consecutive patients with confirmed pancreatic adenocarcinoma and 625 healthy controls. Allele and genotype frequencies for 16 SNPs in DNA repair genes ERCC1, XPD/ERCC2, XPC, XPF/ERCC4, OGG1, and XRCC1 were compared after adjusting for age, sex, and smoking history. Subgroup analysis by sex and smoking history was performed. Carriers of one or two ...
We hypothesized that tumors exposed to high levels of IGF1R ligands are dependent on IGF1R for growth and survival. This would manifest as enhanced sensitivity to tumor inhibition of IGF1R in patients with high levels of ligands or of IGFBP-3, a binding protein that stabilizes circulating ligands and is cleaved by local proteases to release ligands at the tissue level. The functions of the other binding proteins are not well characterized but may sequester ligands in circulation and away from tissues; therefore, low levels of these binding proteins would promote IGF1R ligand availability and thus tumor dependence on IGF1R.. In this phase II study of ganitumab and gemcitabine in metastatic pancreatic adenocarcinoma, baseline levels of circulating factors of the IGF axis were evaluated for potential associations with survival. The treatment effect of ganitumab was enhanced in patients with higher baseline levels of total IGF-1, IGF-2, and IGFBP-3 and lower baseline levels of IGFBP-2 as compared ...
A subepitheal myofibroblastic (SMF) cell layer has been described in the colon, and referred to as pericryptal myofibroblastic cell layer. SMF cells have been shown to produce basement membrane proteins, including type IV collagen and laminin. The aim of this work was to determine the status of the SMF cell layer in Barretts metaplasia (BM), with and without dysplasia, and compare that to the previously reported distribution of SMF in normal colon and colonic adenomas and carcinoma. Sections of formalin-fixed, paraffin-embedded biopsies from 6 colonic adenomas and 5 colonic adenocarcinomas, as well as 4 cases of BM without dysplasia, 4 with low grade dysplasia, 4 high grade dysplasia and 4 with invasive adenocarcinoma were immunohistochemically stained for alpha smooth muscle actin using the immunoperoxidase method. A continuous layer of SMF cells was present in all normal colonic tissue and adenomas but was absent in all colorectal adenocarcinomas. Surprisingly, none of the cases of BM with or without
Background and Objectives: To investigate critical prognostic factors for local recurrence in patients with rectal adenocarcinoma.. Methods: We enrolled 221 consecutive patients who had histologically confirmed adenocarcinoma of the rectum and underwent surgery in our hospital between January 2000 and December 2014. Total mesorectal excision was performed in all patients undergoing a sphincter-sparing procedure or abdominal perineal resection of rectal cancer. To evaluate prognostic factors for local recurrence, we performed univariate and multivariate Cox regression analyses of the local recurrence rate in all patients. Overall survival rates were calculated using the Kaplan-Meier method, and Kaplan-Meier survival curves were compared using the log-rank test.. Results: After the inclusion of only model variables of local recurrence with the highest or lowest univariate risk, a tumor size of ,5 cm, a negative circumferential margin, well-to-moderately differentiated adenocarcinoma, low anterior ...
The Notch pathway has been implicated in a number of malignancies with different roles that are cell- and tissue-type dependent. Notch1 is a putative oncogene in non-small cell lung cancer (NSCLC) and activation of the pathway represents a negative prognostic factor. To establish the role of Notch1 in lung adenocarcinoma, we directly assessed its requirement in Kras-induced tumorigenesis in vivo using an autochthonous model of lung adenocarcinoma with concomitant expression of oncogenic Kras and deletion of Notch1. We found that Notch1 function is required for tumor initiation via suppression of p53-mediated apoptosis through the regulation of p53 stability. These findings implicate Notch1 as a critical effector in Kras-driven lung adenocarcinoma and as a regulator of p53 at a posttranslational level. Moreover, our study provides new insights to explain, at a molecular level, the correlation between Notch1 activity and poor prognosis in patients with NSCLC carrying wild-type p53. This ...
Background: The tumor-stroma ratio (TSR) represents the percentage of neoplastic cell components compared to the combined area of neoplastic cells and the surrounding tumor-induced stroma. A low TSR (predomination of stromal component) has been demonstrated to be an independent adverse prognostic factor in cancers of several organs. In cervical carcinoma patients, TSR has been evaluated in only one previous study with different histological types. The present study aimed to assess the prognostic value of TSR in early stage cervical cancer patients with adenocarcinoma histology only. Materials and Methods: Histological slides of patients with early stage (IB-IIA) cervical adenocarcinoma who underwent surgical treatment between January 2003 and December 2011 were reviewed. Patients who had received preoperative chemotherapy were excluded. TSR was categorized as low (,50%) and high (≥50%). Correlations between TSR and clinicopathological variables were evaluated. Prognostic values of TSR and ...
