Triple-negative breast cancer comprises 15–20% of all breast cancer cases [3] and affects more young women or women with a mutation in the BRCA1 gene than other breast cancers. [4] Triple-negative breast cancers comprise a very heterogeneous group of cancers. TNBC is the most challenging breast cancer type to treat. [5]
Triple-negative breast cancer acts aggressively, grows quickly, spreads further and is more likely to return, the American Cancer Society says. It often occurs in women younger than 40, Black ...
MDA-MB-231 cells were derived from a pleural effusion due to an adenocarcinoma originating in a 51-year-old caucasian female. [2] The cell line is triple negative, meaning it lacks oestrogen receptors, progesterone receptors, and HER2 (human epidermal growth factor receptor 2) amplification which many current treatment options rely on making it difficult to cure.
Conversely, triple negative cancer (i.e. no positive receptors), lacking targeted treatments, now has a comparatively poor prognosis. [42] [43] Androgen receptor is expressed in 80-90% of ER+ breast cancers and 40% of "triple negative" breast cancers. Activation of androgen receptors appears to suppress breast cancer growth in ER+ cancer while ...

The Triple Negative Breast Cancer Foundation ("TNBC Foundation") is a nonprofit organization dedicated to raising awareness of triple negative breast cancer.The foundation supports scientists and researchers in their efforts to determine the definitive causes of triple negative breast cancer so that effective detection, diagnosis, prevention, and treatment can be pursued and achieved.
The application of a murine cancer cell line, such as 4T1, in a mouse model is of great value for preclinical TNBC studies. The 4T1 cell line is widely used as a syngeneic model for human triple-negative breast cancer, which is responsible for more than 17% of breast cancers diagnosed worldwide each year.
