RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.

The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Tumors or cancer of the MAMMARY GLAND in animals (MAMMARY GLANDS, ANIMAL).
Small double-stranded, non-protein coding RNAs (21-31 nucleotides) involved in GENE SILENCING functions, especially RNA INTERFERENCE (RNAi). Endogenously, siRNAs are generated from dsRNAs (RNA, DOUBLE-STRANDED) by the same ribonuclease, Dicer, that generates miRNAs (MICRORNAS). The perfect match of the siRNAs' antisense strand to their target RNAs mediates RNAi by siRNA-guided RNA cleavage. siRNAs fall into different classes including trans-acting siRNA (tasiRNA), repeat-associated RNA (rasiRNA), small-scan RNA (scnRNA), and Piwi protein-interacting RNA (piRNA) and have different specific gene silencing functions.
Variation in a population's DNA sequence that is detected by determining alterations in the conformation of denatured DNA fragments. Denatured DNA fragments are allowed to renature under conditions that prevent the formation of double-stranded DNA and allow secondary structure to form in single stranded fragments. These fragments are then run through polyacrylamide gels to detect variations in the secondary structure that is manifested as an alteration in migration through the gels.

Breast carcinoma developing in patients on hormone replacement therapy: a histological and immunohistological study. (1/806)

AIM: To study the histopathological features of breast carcinoma developing in postmenopausal patients on hormone replacement therapy (HRT). METHODS: The sample comprised 60 patients with invasive breast carcinoma including 31 who had received HRT at or shortly before presentation, and 29 who had not. Details concerning their tumour size, histological type and grade, lymph node status, and oestrogen and progesterone receptor status were compared. Immunoperoxidase staining for Bcl-2, p53, and E-cadherin was carried out on paraffin sections of all 60 patients. The results were then statistically analysed. RESULTS: Tumours detected in HRT patients were significantly smaller (mean 17 mm v 25 mm; p = 0.0156) and of a lower histological grade (p = 0.0414) than those detected in non-HRT patients. The incidence of invasive lobular carcinoma was slightly higher in HRT patients (19% v 14%). Immunohistologically, 87% of HRT tumours were Bcl-2 positive (compared with 79% in the control group), 29% were p53 positive (45% in the control), and 48% were E-cadherin positive (72% in the control group). Although the differences were not statistically significant there was a trend towards higher incidence of p53 negative and E-cadherin negative tumours in HRT patients. CONCLUSIONS: Breast carcinomas detected in patients on HRT have a significantly higher incidence of two favourable prognostic features (small size and a low histological grade). They also show a trend, statistically not significant, of being p53 negative and E-cadherin negative; this may be related to the slightly higher incidence of invasive lobular tumours in these patients.  (+info)

Spectral morphometric characterization of breast carcinoma cells. (2/806)

The spectral morphometric characteristics of standard haematoxylin and eosin breast carcinoma specimens were evaluated by light microscopy combined with a spectral imaging system. Light intensity at each wavelength in the range of 450-800 nm was recorded for 10(4) pixels from each field and represented as transmitted light spectra. A library of six characteristic spectra served to scan the cells and reconstruct new images depicting the nuclear area occupied by each spectrum. Fifteen cases of infiltrating ductal carcinoma and six cases of lobular carcinoma were examined; nine of the infiltrating ductal carcinoma and three of the lobular carcinoma showed an in situ component. The spectral morphometric analysis revealed a correlation between specific patterns of spectra and different groups of breast carcinoma cells. The most consistent result was that lobular carcinoma cells of in situ and infiltrating components from all patients showed a similar spectral pattern, whereas ductal carcinoma cells displayed spectral variety. Comparison of the in situ and the infiltrating ductal solid, cribriform and comedo carcinoma cells from the same patient revealed a strong similarity of the spectral elements and their relative distribution in the nucleus. The spectrum designated as number 5 in the library incorporated more than 40% of the nuclear area in 74.08% of the infiltrating lobular cells and in 13.64% of the infiltrating ductal carcinoma cells (P < 0.001). Spectrum number 2 appeared in all infiltrating ductal cells examined and in none of the lobular cells. These results indicate that spectrum number 5 is related to infiltrating lobular carcinoma, whereas spectrum number 2 is characteristic for infiltrating ductal carcinoma cells. Spectral similarity mapping of central necrotic regions of comedo type in situ carcinoma revealed nuclear fragmentation into defined segments composed of highly condensed chromatin. We conclude that the spectral morphometric features found for lobular and ductal cell populations may serve future automated histological diagnostics.  (+info)

Vascular stroma formation in carcinoma in situ, invasive carcinoma, and metastatic carcinoma of the breast. (3/806)

The generation of vascular stroma is essential for solid tumor growth and involves stimulatory and inhibiting factors as well as stromal components that regulate functions such as cellular adhesion, migration, and gene expression. In an effort to obtain a more integrated understanding of vascular stroma formation in breast carcinoma, we examined expression of the angiogenic factor vascular permeability factor (VPF)/vascular endothelial growth factor (VEGF); the VPF/VEGF receptors flt-1 and KDR; thrombospondin-1, which has been reported to inhibit angiogenesis; and the stromal components collagen type I, total fibronectin, ED-A+ fibronectin, versican, and decorin by mRNA in situ hybridization on frozen sections of 113 blocks of breast tissue from 68 patients including 28 sections of breast tissue without malignancy, 18 with in situ carcinomas, 56 with invasive carcinomas, and 8 with metastatic carcinomas. A characteristic expression profile emerged that was remarkably similar in invasive carcinoma, carcinoma in situ, and metastatic carcinoma, with the following characteristics: strong tumor cell expression of VPF/VEGF; strong endothelial cell expression of VPF/VEGF receptors; strong expression of thrombospondin-1 by stromal cells and occasionally by tumor cells; and strong stromal cell expression of collagen type I, total fibronectin, ED-A+ fibronectin, versican, and decorin. The formation of vascular stroma preceded invasion, raising the possibility that tumor cells invade not into normal breast stroma but rather into a richly vascular stroma that they have induced. Similarly, tumor cells at sites of metastasis appear to induce the vascular stroma in which they grow. We conclude that a distinct pattern of mRNA expression characterizes the generation of vascular stroma in breast cancer and that the formation of vascular stroma may play a role not only in growth of the primary tumor but also in invasion and metastasis.  (+info)

Diffuse type gastric and lobular breast carcinoma in a familial gastric cancer patient with an E-cadherin germline mutation. (4/806)

E-Cadherin alterations have been reported frequently in sporadic diffuse type gastric and lobular breast carcinomas. Germline mutations of this gene have been identified recently in several gastric cancer families. We analyzed seven patients with a family history of the disease who had diffuse type gastric cancer diagnosed before the age of 45 for germline mutations in CDH1, the gene encoding the E-cadherin protein. We identified a frameshift mutation in exon 3 in one patient with a strong family history of gastric cancer. The same germline mutation was found in the patient's mother, who had metachronous development of lobular breast and diffuse type gastric carcinomas. Immunohistochemistry for E-cadherin protein expression revealed an abnormal staining pattern in both of these tumors, suggesting complete inactivation of the cell adhesion molecule. Thus, our finding suggests that besides diffuse type gastric cancer, lobular breast carcinomas may be associated with germline CDH1 mutations.  (+info)

Comparison of dual-head coincidence gamma camera FDG imaging with FDG PET in detection of breast cancer and axillary lymph node metastasis. (5/806)

Dual-head coincidence gamma camera 18F-fluorodeoxyglucose (FDG) imaging was compared with FDG PET in the detection of breast cancer and axillary lymph node metastasis. METHODS: Both coincidence gamma camera FDG imaging and FDG PET were performed in a cylindrical phantom containing spheres of different sizes and activity ratios (5:1, 10:1 and 15:1) and in 30 women (age range 32-78 y) with suspected breast cancer. Biopsies or mastectomies were performed in all patients. Images were visually assessed, and the count ratio between tumor and normal tissue (T/N ratio) was calculated. RESULTS: In the phantom studies, coincidence gamma camera imaging visualized the smallest sphere (1.0 cm) at a ratio of 15:1 but not at ratios of 5:1 and 10:1. Coincidence gamma camera imaging visualized the other spheres (> or =1.3 cm) at all ratios. PET visualized all spheres at all ratios. In the clinical studies, 22 of 26 breast carcinomas detected by PET were also detected by coincidence gamma camera imaging.. Coincidence gamma camera imaging detected all of the carcinomas > or =2 cm in diameter (n = 10) and 12 of 16 carcinomas <2 cm. In breast carcinomas detected by both PET and coincidence gamma camera imaging, the T/N ratio in non-attenuation-corrected PET (7.12 +/- 7.13) was significantly higher than in coincidence gamma camera imaging (2.90 +/- 1.47, P < 0.005). Four of 8 axillary lymph node metastases detected by PET were detected by coincidence gamma camera imaging. Of 9 axillary lymph node metastases <1.0 cm in diameter, 7 and 3 were detected by PET and coincidence gamma camera imaging, respectively. CONCLUSION: Coincidence gamma camera imaging is useful in detecting breast carcinoma > or =2 cm in diameter but is not reliable for breast carcinoma <2 cm in diameter. Coincidence gamma camera imaging may be useless or even dangerous in the detection of axillary lymph node metastasis.  (+info)

Expression of a novel factor in human breast cancer cells with metastatic potential. (6/806)

Clinical and experimental evidence suggests that tumor cells shed into the circulation from solid cancers are ineffective in forming distant metastasis unless the cells are able to respond to growth conditions offered by the secondary organs. To identify the phenotypic properties that are specific for such growth response, we injected carcinoma cells, which had been recovered from bone marrow micrometastases in a breast cancer patient who was clinically devoid of overt metastatic disease and established in culture, into the systemic circulation of immunodeficient rats. The animals developed metastases in the central nervous system, and metastatic tumor cells were isolated with immunomagnetic beads coated with an antibody that was reactive with human cells. The segregated cell population was compared with the injected cells by means of differential display analysis, and two candidate fragments were identified as up-regulated in the fully metastatic cells. The first was an intracellular effector molecule involved in tyrosine kinase signaling, known to mediate nerve growth factor-dependent promotion of cell survival. The second was a novel gene product (termed candidate of metastasis-1), presumably encoding a DNA-binding protein of helix-turn-helix type. Constitutive expression of candidate of metastasis-1 seemed to distinguish breast cancer cells with metastatic potential from cells without metastatic potential. Hence, our experimental approach identified factors that may mediate the growth response of tumor cells upon establishment in a secondary organ and, thereby, contribute to the metastatic phenotype.  (+info)

Epidemiology of contralateral breast cancer. (8/806)

Two to 11% of women diagnosed with breast cancer will develop contralateral breast cancer in their lifetime. Women with a first primary are at a 2-6-fold increased risk of developing contralateral breast cancer compared with the risk in the general population of women developing a first primary cancer. The incidence rate of contralateral breast cancer varies from four to eight per 1000 person-years. To assess the risk factors associated with the development of contralateral breast cancer among women with a first primary breast cancer, the epidemiological literature concerning these factors was reviewed and summarized. Studies have shown that a family history of breast cancer, an early age at initial diagnosis, and a lobular histology of the first primary breast cancer increase the risk of developing contralateral breast cancer. Although chemotherapy and tamoxifen therapy may reduce this risk, there are inconsistent results regarding the effects of radiotherapy and the effects of reproductive, environmental and other factors. Additional analytical studies addressing all potential risk factors associated with the development of contralateral breast cancer are necessary in view of the increasing incidence and survival of women with a first primary.  (+info)

Abstract. Lobular carcinoma in situ is a form of in situ neoplasia that develops within the terminal lobules of the breast. It is an extremely rare finding in males due to the lack of lobular development in the male breast. The authors herein report an unusual case of incidentally discovered lobular carcinoma in situ in a male patient with recurrent bilateral gynecomastia who was subsequently diagnosed with invasive ductal carcinoma of the left breast. The pathology of lobular carcinoma in situ in a male as well as screening MRI surveillance of male patients at high risk for breast cancer are discussed, emphasizing the importance of screening and imaging follow up in men who are at high risk for breast cancer..

ISSN 0718-4026. http://dx.doi.org/10.4067/S0718-40262007000300010.. Introduction: Although breast cancer most frequently metastasizes to the linfatic nodes, bones, lungs and liver, it can also affect the gastrointestinal tract, peritoneum and gynecology organs. Material and methods: We describe three cases of peritoneal carcinomatosis secondary to metastatic dissemination of an infiltrating lobular breast cancer. In the three cases diagnosis was realized many years after the delivering of the primary tumour and in two cases we observed tumour remission at one and four years respectively after administration of chemotherapy and hormonal therapy postoperative. Conclusion: Peritoneal carcinomatosis in breast cancer is rare, but when appears it is usually secondary to infiltrating lobular breast cancer with positive hormonal receptors. The symptoms are unspecific ...

Invasive lobular carcinoma (ILC) comprises approximately 10% of breast cancers and appears to have a distinct biology. Because it is less common than infiltrating ductal carcinoma (IDC), few data have been reported that address the biologic features of ILC in the context of their clinical outcome. In the present study we undertook an extensive comparison of ILC and IDC using a large database to provide a more complete and reliable assessment of their biologic phenotypes and clinical behaviors. The clinical and biological features of 4140 patients with ILC were compared with those of 45,169 patients with IDC (not otherwise specified). The median follow-up period was 87 months. In comparison with IDC, ILC was significantly more likely to occur in older patients, to be larger in size, to be estrogen and progesterone receptor positive, to have lower S-phase fraction, to be diploid, and to be HER-2, p53, and epidermal growth factor receptor negative. It was more common for ILC than for IDC to metastasize to
In rare cases, breast cancer can start in other areas of the breast. It can be invasive or noninvasive. Invasive means it has spread from the milk duct or lobule to other tissues in the breast. Noninvasive means it has not yet invaded other breast tissue. Noninvasive breast cancer is also called in situ. Ductal carcinoma in situ (DCIS), or intra-ductal carcinoma, is breast cancer in the lining of the milk ducts that has not yet invaded nearby tissues. It may progress to invasive cancer if untreated. Lobular carcinoma in situ (LCIS) is a marker for an increased risk of invasive cancer in the same or both breasts. Once a woman has been diagnosed with breast cancer, a series of tests will be done to ensure that the stage and classification of the cancer is accurate. Today, breast cancer can be treated in several ways, which will depend on the type and how far it has spread.. ...

We started our conversation with Susans story…. Susan shared that she had mammograms done every year. Also, her mother was a volunteer for the American Cancer Society for many years. However, despite her knowledge and her yearly checkups she was diagnosed at 45 years old, in August of 2008.. Susan told us that it started with a sharp pain in her right breast. She explained that it was a pain that was not normal. She shared this with her husband and he encouraged her to get it checked out. So three days later she went in to get it looked at.. Her mammogram was clear but they saw a faint shadow during the ultrasound so they sent her for a biopsy. The biopsy showed that she did in fact have Breast Cancer. However, this wasnt the typical breast cancer that you hear about, she had Lobular Breast Cancer. This is a different kind of cancer, it doesnt look like the typical breast cancer so it is harder to diagnose. Lobular Breast Cancer is called the sneaky cancer because it grows in strands ...
Lobular carcinoma in situ isnt cancer. LCIS means that some cells lining the lobules of the breast tissue have started to turn into cancer cells.
The dataset has been developed for the reporting of resection specimens for ductal carcinoma in situ (DCIS) of the breast. The protocol applies to cases of DCIS and for where microinvasion (≤1 mm) is present. It also covers other in situ lesions including pleomorphic and florid variants of lobular carcinoma in situ (LCIS), as well as encapsulated papillary carcinoma and solid papillary carcinoma in situ. This dataset may also be used in those rare cases of DCIS removed at core biopsy but without evidence of residual DCIS in a subsequent excision specimen. This protocol should only be used for re-excisions when they contain the largest extent of DCIS ...

There two principal types of breast cancer that appear as lumps in the breast. They are ductal carcinoma and lobular carcinoma. Ductal carcinoma, as suggested by the name, is found in the ducts of the breast, while lobular carcinoma is found in the lobules.Ductal CarcinomaCancerous lumps in the breast identified as ductal carcinoma are in the ducts of the breast that carry milk.Lobular CarcinomaA lobular carcinoma breast lump originates in the lobules or the glands in the breast that produce milk.What is it?Cancer is an abnormality in the genes that are responsible for growing healthy cells. Unchecked, these abnormal cells will continue to...
It is generally believed that atypical ductal hyperplasia (ADH) is a direct precursor of breast cancer and therefore portends breast cancer in the same breast, while atypical lobular hyperplasia (ALH) has an equal risk of cancer in both breasts and may not be a direct precursor of breast cancer. In the study, however, published in Cancer Prevention Research (2014;7;211-217) and led by Lynn C. Hartmann, MD, Professor of Oncology, cancer was twice as likely to occur in the breast having the biopsy, and this was true for both ADH and ALH.. Moreover, the findings run counter to current understanding that ALH primarily leads to lobular cancer. Instead, the researchers discovered that ALH was associated predominantly with later ductal cancers of the breast-also similar to cancers after ADH.. Both types resulted in invasive ductal cancers, and 69 percent were of intermediate or high grade. Further, about 25 percent had spread to the lymph nodes. Although the numbers were not statistically significant, ...

Reducing cholesterol levels may inhibit breast cancer development, but the long-term use of cholesterol-lowering statin drugs is associated with more than double the risk of both types of breast cancer: invasive ductal carcinoma and invasive lobular carcinoma.
Breast cancer affects a large number of females in the Western world, accounting for half a million deaths worldwide on an annual basis. Carcinoma of the breast is a heterogeneous disease based on pathological criteria, which is probably due to the multiplicity of genetic lesions that have accumulated during tumor development, resulting in distinct tumor types. The most frequently observed subtypes, invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC), are very distinct phenotypically as well as biochemically (Coradini et al., 2002; Korkola et al., 2003; Mathieu et al., 2004; Zhao et al., 2004; Stange et al., 2006). ILC is a subtype of breast cancer that accounts for 10-15% of all cases and has a greater tendency for multifocal development and bilateral presentation than other primary breast tumors (Newstead et al., 1992; Krecke and Gisvold, 1993; Helvie et al., 1993). Classical ILC is characterized by non-cohesive invasive cells that are arranged in trabecules without mass ...

Introduction. Invasive lobular carcinoma is associated with a higher rate of multifocality than other types of breast cancer. Breast MRI is commonly performed in patients diagnosed with ILC to assess for additional disease prior to formulating a management plan. MRI may be both time consuming and costly and can delay treatment.. Recently tomosynthesis has become an adjunct in the assessment and diagnosis of breast cancer. It is readily available at the time of mammography therefore providing information at the one stop clinic. We proposed that it may be possible to use tomosynthesis to assess for multifocality in ILC in place of MRI.. Method. A retrospective review of all cases of ILC diagnosed at a single regional screening unit over a 3-year period was performed. Patients having surgery as primary treatment were included. Ninety-eight patients were identified, 29 having both MRI and tomosynthesis in addition to mammography and ultrasound scan as part of their assessment. Histological data was ...
