Scientists study the behaviour of isolated cells grown in the laboratory for insights into how cells function in the body in health and disease. Experiments using cell culture are used for developing new diagnostic tests and new treatments for diseases. This is a list of major breast cancer cell lines that are primarily used in breast cancer ...
Clarke’s research team and collaborators discovered a new signaling network and control mechanism that contributes to the hormonal regulation of breast cancer cell proliferation and cell death in response to estrogens, [9] [10] aromatase inhibitors, and antiestrogens [11] This signaling includes communication between the endoplasmic reticulum ...
MDA-MB-468 is a cell line that was isolated from a 51-year-old female human in 1977, and is commonly used in breast cancer research. MDA-MB-468 cells were extracted from a pleural effusion of mammary gland and breast tissues, and have proven useful for the study of metastasis, migration, and breast cancer proliferation.
Cancer cell heterogeneity can cause disease progression when molecularly targeted therapy, fails to kill those tumor cells which do not express the marker, then divide and mutate further, creating a new heterogeneous tumour. In breast cancer models of the mouse the immune microenvironment affects susceptibility to neoadjuvant chemotherapy. In ...
Checkpoint-control proteins that trigger cell cycle arrest in response to DNA damage or chromosomal defects (e.g., breast cancer type 1 susceptibility protein (BRCA1), p16, and p14). [15] Proteins that induce apoptosis. If damage cannot be repaired, the cell initiates programmed cell death to remove the threat it poses to the organism as a whole.
MCF-7 is a breast cancer cell line isolated in 1970 from a 69-year-old White woman. [1] MCF-7 is the acronym of Michigan Cancer Foundation-7, referring to the institute in Detroit where the cell line was established in 1973 by Herbert Soule and co-workers. [2] The Michigan Cancer Foundation is now known as the Barbara Ann Karmanos Cancer ...
Pregnancy has a positive effect on the prognosis of breast cancer according to several studies [43] [44] [45] and it apparently increases the chance of survival after diagnosis of breast cancer. [46] Possible positive effects of pregnancy could be explained by the persistence of fetal cells in the blood and maternal tissues. [2]
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
