SRP108576 PRJNA389215 GSE99648 MeDIP-sequencing of shSRC-1 and shNT tamoxifen treated LY2 cells The steroid co-activator protein SRC-1 plays an important role in endocrine therapy resistant breast cancer. Its expression is associated with large high grade tumours, HER2 positivity, disease recurrence and resistance to endocrine therapy. While SRC-1 typically functions to activate gene expression, some evidence has pointed towards a potential role in repression. This study looks into the effects of a stable knockdown of SRC-1 in a tamoxifen resistant cell line, LY2, and the effects of this knock down on the methylation landscape. Overall design: We report the MeDIP-sequencing of tamoxifen treated LY2 breast cancer cells treated with non-targeting shRNA or SRC-1 (NCOA1) targeting shRNA and examine the methylation differences.
