While ovarian cancer remains the most lethal gynecological malignancy in the United States, there are no biomarkers available that are able to predict therapeutic responses to ovarian malignancies. OVCAR3 cells were treated with EGF1, and the time course of cell progression was monitored based on Akt phosphorylation and growth dynamics. EGF-stimulated Akt phosphorylation was detected at 12 h post-treatment, but an impact on expansion was not really noticed until 48 l post-exposure. Growth-stimulated mobile lysates had been examined for proteins single profiles between treatment organizations and across period factors using iTRAQ marking and mass spectrometry. The proteins response to EGF treatment was determined via iTRAQ evaluation in EGF-stimulated lysates relatives to vehicle-treated individuals across the treatment period program. Approval research had been performed on one of the controlled aminoacids differentially, lysosomal-associated membrane layer INK 128 proteins 1 (Light-1), in human ...

Cell lines and culture. The derivation, source, and propagation of human epithelial ovarian cancer cell lines, such as cisplatin-sensitive (A2780-PAR) and platinum-resistant (A2780-CP20 and RMG2) epithelial ovarian cancer cell lines, were maintained as previously described (30). The A2780-CP20 cell line was developed by sequential exposure of the A2780 cell line to increasing concentrations of cisplatin. All experiments were done with 70% to 80% confluent cultures.. ATP7A and ATP7B gene silencing by siRNA. siRNA constructs targeted to ATP7A and ATP7B were designed and purchased from Qiagen. The target sequences were 5′-CTGGACCGGATTGTTAATTAT-3′ (for ATP7A) and 5′-CCAATTGATATTGAGCGGTTA-3′ (for ATP7B). In vitro transient transfection was done as described previously (28). Briefly, cells were transfected with ATP7A- and/or ATP7B-specific or scrambled (control) siRNA using RNAiFect reagent (Qiagen). At selected time intervals, cells were harvested to measure mRNA and protein levels of ATP7B ...
Xu, J., et al. Mass spectrometry-based peptidome profiling of human serous ovarian cancer tissues. The International Journal of Biochemistry & Cell Biology. S1357-2725(18)30258-9. 10/12/2018.. We identified 634 differentially expressed peptides, 508 of these peptides were highly abundant in serous ovarian cancer tissues, a result consistent with higher protease activity in ovarian cancer patients. The difference in preferred cleavage sites between the serous ovarian cancer tissues and normal ovarian epithelium indicates the characteristic peptidome of ovarian cancer and the nature of cancer-associated protease activity. Interestingly, KEGG pathway analysis of the peptide precursors indicated that the differentially regulated pathways in ovarian cancer are highly consistent with the pathways discovered in other cancers. Besides, we found that a proportion of the differentially expressed peptides are similar to the known immune-regulatory peptides and anti-bacterial peptides. Then we further ...
Vectors based on adenoviruses have been designed as targeted anti-cancer therapeutics that showed promising results in pre-clinical applications. In clinical trials, these oncolytic adenoviruses have generally been proved safe in patients, but have fallen short of their expected therapeutic value. In this thesis the susceptibility of primary ovarian cancer cells to oncolytic adenoviruses was studied in order to identify cellular mechanisms that confer resistance to virotherapy. Using gene expression profiling of cancer cells either resistant or susceptible to viral oncolysis, it was discovered that the epithelial phenotype of ovarian cancer represents a barrier to infection by commonly used oncolytic adenoviruses targeted to coxsackie- and adenovirus receptor (CAR) or CD46. Accessibility to viral receptors was critically linked to depolarization and the loss of tight and adherens junctions, both hallmarks of epithelial-mesenchymal transition (EMT). Importantly, tumors in situ as well as ...

A DNA repair pathway-focused score has the potential to help determine if first-line platinum based chemotherapy can benefit advanced-stage ovarian cancer patients, according to a study published April 13 in the Journal of the National Cancer Institute.. Most ovarian cancer patients are diagnosed with advanced disease (stages III and IV). They undergo surgery to remove as much tumor as possible, and then undergo platinum-based chemotherapy. But tools to predict response to platinum-based chemotherapy in ovarian cancer patients have been inadequate.. In order to determine if a DNA repair pathway-focused score could help predict outcomes for ovarian cancer patients treated with platinum-based chemotherapy, Josephine Kang, M.D., Ph.D., of the Department of Radiation Oncology at Dana Farber Cancer Institute, and colleagues gathered gene expression data from The Cancer Genome Atlas (TCGA) database for patients with advanced stage ovarian cancer, and established a molecular score by looking at the ...

... is a type of cancer that begins in a womens ovaries. Women have two ovaries that produce eggs as well as the hormones estrogen and progesterone. Ovarian cancer can be hard to diagnose because early-stages of ovarian cancer rarely cause any symptoms and advanced-stage ovarian cancer may cause few and nonspecific symptoms. The symptoms of ovarian cancer may include abdominal bloating, quickly feeling full when eating, weight loss, cramping in the lower stomach, changes in bowel habits, and a frequent need to urinate.. The cause of ovarian cancer is unclear. In general, cancer is caused by genetic mutations that turn normal cells into abnormal cancer cells that quickly multiply, forming a mass (tumor). The type of cell where the cancer begins determines the type of ovarian cancer. These types included epithelial tumor, stromal tumor, and germ cell tumor. Certain factors may increase your risk of ovarian cancer. These include age (most common in women ages 50 to 60), estrogen hormone ...
The distribution of genotypes for Arg399Gln XRCC1 polymorphism in ovarian cancers vs. controls was: 58.0% vs. 38.5% for Arg/Arg, 32.0% vs. 26.9% for Arg/Gln, and 10.0% vs. 34.6% for Gln/Gln genotype, respectively. We found that XRCC1 Arg allele is associated with ovarian cancer risk (OR= 2.635 for Arg vs. Gln with 95% CI of 1.526 to 4.550). The Arg allele exerts its effect on increased risk for ovarian cancer development in dominant model (Arg/Arg plus Arg/Gln vs. Gln/Gln) with OR (and 95 % CI) of 4.765 (1.692 to 13.414) as well as in recessive model (Arg/Arg vs. Arg/Gln plus Gln/Gln) with OR (and 95 % CI) of 2.210 (1.072 to 4.555). ...

AU - Lai, Hung Cheng. PY - 2019/11/27. Y1 - 2019/11/27. N2 - Background: Ovarian cancer (OC) is the most lethal gynecological cancer, worldwide, largely due to its vague and nonspecific early stage symptoms, resulting in most tumors being found at advanced stages. Moreover, due to its relative rarity, there are currently no satisfactory methods for OC screening, which remains a controversial and cost-prohibitive issue. Here, we demonstrate that Papanicolaou test (Pap test) cervical scrapings, instead of blood, can reveal genetic/epigenetic information for OC detection, using specific and sensitive DNA methylation biomarkers. Results: We analyzed the methylomes of tissues (50 OC tissues versus 6 normal ovarian epithelia) and cervical scrapings (5 OC patients versus 10 normal controls), and integrated public methylomic ...
In this study a new low-grade serous ovarian carcinoma cell line, named as CAISMOV24, was characterized in terms of its in vitro cell growth, production of soluble biomarkers and expression of cell surface molecules. Additionally, CAISMOV24 was molecularly characterized and compared to its primary malignant cells for genomic alterations. In vitro models of well-characterized low-grade serous ovarian cell lines are currently limited in the literature. CAISMOV24 resulted from the in vitro spontaneous immortalization of primary malignant cells from ascites that was associated with a low-grade serous ovarian carcinoma. Although malignant cells of ovarian neoplasia from either tumor tissue or ascites can be cultivated in vitro for a limited period, only a minority of the primary cell cultures may become cell lines [14]. Spontaneous immortalization of primary cultures of malignant cells is an event occurring at a very low frequency. As an example, ODonnell et al. [11] reported the occurrence of only ...

Research highlights: {yields} PPAR{gamma} ligands increased the rate of apoptosis and inhibition of proliferation in ovarian cancer cells. {yields} PPAR{gamma} ligands induced p63 and p73 expression, but not p53. {yields} p63 and p73 leads to an increase in p21 expression and apoptosis in ovarian cancer cells with treatment PPAR{gamma} ligands. {yields} These findings suggest that PPAR{gamma} ligands suppressed growth of ovarian cancer cells through upregulation of p63 and p73. -- Abstract: Peroxisome proliferator-activated receptor gamma (PPAR{gamma}) agonists, including thiazolidinediones (TZDs), can induce anti-proliferation, differentiation, and apoptosis in various cancer cell types. This study investigated the mechanism of the anticancer effect of TZDs on human ovarian cancer. Six human ovarian cancer cell lines (NIH:OVCAR3, SKOV3, SNU-251, SNU-8, SNU-840, and 2774) were treated with the TZD, which induced dose-dependent inhibition of cell growth. Additionally, these cell lines exhibited ...
Purpose: Curcumin, a component of turmeric, has been shown to suppress inflammation and angiogenesis largely by inhibiting the transcription factor nuclear factor-κB (NF-κB). This study evaluates the effects of curcumin on ovarian cancer growth using an orthotopic murine model of ovarian cancer.. Experimental Design:In vitro and in vivo experiments of curcumin with and without docetaxel were done using human ovarian cancer cell lines SKOV3ip1, HeyA8, and HeyA8-MDR in athymic mice. NF-κB modulation was ascertained using electrophoretic mobility shift assay. Evaluation of angiogenic cytokines, cellular proliferation (proliferating cell nuclear antigen), angiogenesis (CD31), and apoptosis (terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling) was done using immunohistochemical analyses.. Results: Curcumin inhibited inducible NF-κB activation and suppressed proliferation in vitro. In vivo dose-finding experiments revealed that 500 mg/kg orally was the optimal dose needed to ...

In addition to serving as a physical support, the extracellular matrix (ECM) actively influences cell behavior. However, the definitive effects of different chemical structures present in the ECM on cell behavior remain obscure. The current study aimed to investigate the effects of different chemical structures present in the ECM on cellular physiology using the ovarian cancer cell line SKOV-3 as a model. Self-assembled monolayers (SAMs) with different chemical modifications, including methyl (-CH|sub|3|/sub|), hydroxyl (-OH), amino (-NH|sub|2|/sub|), carboxyl (-COOH), and mercapto (-SH) groups, were used as microenvironmental models to explore the effects of different structures on SKOV-3 cells. The cell morphology, cell adhesion, cytotoxicity, and functional alterations in cancer cells cultured on different SAMs were analyzed. The results showed that SKOV-3 cells cultured on -NH|sub|2|/sub| surfaces exhibited the largest contact area, whereas those on -CH|sub|3|/sub| surfaces exhibited the smallest

Researchers at the University of Illinois have identified biomarkers that can be used to determine ovarian cancer survival and recurrence, and have shown how these biomarkers interact with each other to affect these outcomes.. Their findings appear in the journal PLOS ONE.. Researchers try to find molecules called biomarkers that help determine a person´s likelihood of getting a disease or, if they have already been diagnosed, how far the disease has advanced. Genes, transcription factors and microRNAs are often used as biomarkers because these molecules can be heralds of disease or portents of susceptibility.. Genes are segments of DNA that code for proteins or other molecules that perform the functions of the cell. Transcription factors regulate these genes by binding to specific DNA sequences, preventing or inducing the genes to be "expressed" at higher or lower levels. MicroRNAs, as their name suggests, are small RNA molecules that regulate an intermediate stage of gene expression. ...

Platinum resistance is a major cause of treatment failure in ovarian cancer. We previously identified matrix metalloproteinase 9 (MMP-9) as a potential therapeutic target of chemoresistant disease. A2780cis (cisplatin-resistant) and A2780 (cisplatin-sensitive) ovarian carcinoma cell lines were used. The cytotoxic effect of MMP-9/MMP-2 inhibitor, (2R)-2-[(4-Biphenylsulfonyl) amino]-3 phenylpropionic acid (C21H19NO4S) alone or in combination with cisplatin was determined using high content screening. Protein expression was examined using immunohistochemistry and ELISA. Co-incubation of cisplatin and an MMP-9/MMP-2 inhibitor, (2R)-2-[(4-Biphenylsulfonyl) amino]-3 phenylpropionic acid (C21H19NO4S) resulted in significantly greater cytotoxicity as compared to either treatment alone in a cisplatin resistant MMP-9 overexpressing cell line; A2780cis. In addition, pre-incubating with MMP-9i prior to cisplatin further enhances the cytotoxic effect. No significant difference was observed in MMP-9 protein in tissue
Cigarette smoking is associated with an increased risk of developing mucinous ovarian tumors but whether it is associated with ovarian cancer survival overall or for the different histotypes is unestablished. Furthermore, it is unknown whether the association between cigarette smoking and survival differs according to strata of ovarian cancer stage at diagnosis. In a large pooled analysis, we evaluated the association between various measures of cigarette smoking and survival among women with epithelial ovarian cancer. We obtained data from 19 case-control studies in the Ovarian Cancer Association Consortium (OCAC), including 9,114 women diagnosed with ovarian cancer. Cox regression models were used to estimate adjusted study-specific hazard ratios (HRs), which were combined into pooled hazard ratios (pHR) with corresponding 95% confidence intervals (CIs) under random effects models. Overall, 5,149 (57%) women died during a median follow-up period of 7.0 years. Among women diagnosed with ovarian cancer,
Question - Platinum resistant ovarian cancer. Tested for TLC and platelet count. What are the risk?. Ask a Doctor about when and why Chemotherapy is advised, Ask an Oncologist
According to the International Federation of Gynecology and Obstetrics (FIGO), EOC with lymph node metastases is classified as FIGO stage IIIC disease, even in the absence of peritoneal metastases. In contrast to patients with FIGO stage I ovarian cancer after a comprehensive staging procedure, patients with a FIGO stage III ovarian cancer obtain adjuvant chemotherapy. Therefore, the recognition of lymph node metastases is of utmost importance. In general, the incidence of lymph node metastases in clinical early stage EOC is approximately 14%, and depends on subtype histology (i.e. serous 23%, mucinous 3%) and differentiation grade (4% and 20% in grade 1 and 3 tumors respectively).. Surgical staging of EOC and the extent of lymph node dissection differs greatly from centre to centre. In case of a clinical early stage ovarian cancer, the Dutch guideline recommends a staging laparotomy with adequate lymph node sampling, with an absolute minimum of ten lymph nodes removed. In the same guideline, a ...
By using sophisticated gene sequencing methods to demonstrate a regulatory link between the stem cell factor Lin28 and the signaling molecule bone morphogenic protein 4, Yale researchers are creating a path for developing new targeted ovarian cancer therapies.. Researchers at Yale School of Medicine have identified a key link between stem cell factors that fuel ovarian cancers growth and patient prognosis. The study, which paves the way for developing novel targeted ovarian cancer therapies, is published online in the current issue of Cell Cycle.. Lead author Dr. Yingqun Huang, associate professor in the Department of Obstetrics, Gynecology & Reproductive Sciences, and her colleagues have demonstrated a connection between two concepts that are revolutionizing the way cancer is treated.. First, the "cancer stem cell" idea suggests that at the heart of every tumor there is a small subset of difficult-to-identify tumor cells that fuel the growth of the bulk of the tumor.

This study was designed to explore the effects of liposome-survivin antisense oligonucleotide (Lip-ASODN) on the growth and apoptosis of human ovarian cancer cell lines, A2780 and SKOV3. To investigate the use of survivin as a therapeutic target on ovarian cancer, we carried out transfections with Lip-ASODN to induce apoptosis in ovarian cancer cell lines, A2780 and SKOV3. The expression of survivin mRNA and relative protein were evaluated separately by quantitative real-time RT-PCR and Western blot analysis. Cell proliferation inhibition was determined by methyl thiazolyl tetrazolium (MTT) assay, and the induced cell apoptosis was examined using flow cytometry (FCM) after Lip-ASODN transfection. Our results showed that the overexpression of survivin led to infinite carcino-proliferation, and survivin expression in the ...

Epithelial ovarian cancer is the most lethal gynecological malignancy and the fifth leading cause of cancer death in women in the Western world. ETS transcription factors have been implicated in the regulation of gene expression during a variety of biological processes including cell growth and differentiation. We recently examined the role of the ETS transcription factor ETV5 in epithelial ovarian cancer and described ETV5 as being up-regulated in ovarian tumor samples as compared to ovarian tissue controls. In ovarian cancer cells, we showed that ETV5 regulated the expression of cell adhesion molecules, enhancing ovarian cancer cell survival in anchorage-independent conditions and suggesting that it plays a role in ovarian cancer cell dissemination and metastasis into the peritoneal cavity To understand the role of ETV5 transcription factor during ovarian cancer cell dissemination, we analyzed by gene expression microarray technology those genes whose expression was altered in an ovarian ...
Background and Aims: Ovarian cancer is one of most common causes of cancer related womens mortalities. Human papilloma virus is a known factor concerning cervical cancer but its role in causing ovarian cancer is not yet verified. A few studies also identified HPV DNA in ovarian carcinoma tissues. However, some studies did not detect HPV DNA in ovarian carcinoma tissues. In this article, we investigated the potential role of high risk HPVs in the ovarian epithelial carcinoma. Methods: Fifty archived epithelial ovarian cancer paraffin blocks were collected. Then, 30 non-malignant ovarian blocks used as control. These samples were histopathologically were confirmed by a pathologist and the proper blocks for DNA extraction and PCR were sorted. PCR was conducted deploying highly specific primers for high-risk types of HPV (18 and 16) according to the instructions of manufacturer company. Results: High-risk oncogenic sequences were identified in 4 (5%) of the 80 studied samples. Of the 4 HPV positive cases
