RNA-seq of breast cancer cell lines post ligand treatment I


ABSTRACT: Goal: study the impact of estrogen receptor ligands on gene expression in HR+ breast cancer cells Methods: RNA sequencing Results: Ligand 4-OH tamoxifen, a selective ER modulator (SERM), promotes transcriptional activation of ER and mimics the transcriptional effect of natural ligand E2 for a subset of ER target genes, consistently across the seven breast cell lines (MCF-7, HCC1500, MDA-MB-330, EFM-19, T-47D, BT-474, and CAMA-1). Selective ER degraders (SERD) fulvestrant and GDC-0927 on the other hand do not induce, or induce very weakly the expression of ER target genes. The effect of GDC-0810 depends on the cellular context.
