General description

Estrogen receptor-positive breast cancer is the most common type of breast cancer. About 80% of all breast cancers express the estrogen receptor (ER+) and depend on estrogen to support the growth and spread of the cancer cells. Hormonal therapy, such as tamoxifen, may help slow or stop the growth of ER+ breast cancers by blocking the actions of estrogen. Primary or acquired tamoxifen resistance poses a major clinical challenge in the treatment of ER+ breast cancer. The MCF-7/S0.5 is the parental line from which many tamoxifen-resistant cell lines have been derived and is utilized as a parental control to its derivative cell lines in parallel experiments.

The presence of hormones in the serum required in tissue culture media complicates the demonstration of specific hormone and antihormone effects. The MCF-7/S0.5 human breast cancer cells have been adapted to long-term growth in low serum concentration (0.5% fetal bovine serum) by a stepwise reduction of the medium serum content from 5% to 0.5% FBS. MCF-7/S0.5 cells express both estrogen and progesterone receptors and are sensitive to tamoxifen.

The human breast cancer cell line MCF-7 requires oestrogen to produce and promote growth of tumours in athymic mice. In vitro, however, MCF-7 cells proliferate rapidly without supply of oestrogen (Briand & Lykkesfeldt, 1984). Oestrogen stimulation of proliferation of MCF-7

In breast cancer, 17β-estradiol (E2) plays critical roles mainly by binding to its canonical receptor, estrogen receptor (ER) α66, and eliciting genomic effects. E2 also triggers rapid, nongenomic responses. E2 activates sphingosine kinase 1 (SphK1), increasing sphingosine-1-phosphate (S1P) that binds

Genomic amplification of 3q26.2 locus leads to the increased expression of microRNA 551b-3p (miR551b-3p) in triple-negative breast cancer (TNBC). Our results demonstrate that miR551b-3p translocates to the nucleus with the aid of importin-8 (IPO8) and activates STAT3 transcription. As a consequence
