RNA-seq of human breast cancer cell lines MCF7 and CAMA1 treated with Fulvestrant, AZD9496 and AZD9833/camizestrant, with and without estradiol

Oral selective estrogen receptor degraders (SERDs) could become the backbone endocrine therapy (ET) for estrogen receptor-positive (ER+) breast cancer, as they achieve greater inhibition of ER-driven cancers than current ETs and overcome key resistance mechanisms. This dataset was aimed at exploring the preclinical effects of the next-generation oral SERD camizestrant (AZD9833) on MCF7 and CAMA1 cell lines. Cells were treated with 1 nM estradiol and 100 nM fulvestrant, AZD9496, or camizestrant for 24 hours, with three replicates per condition and non-estradiol-treated controls.
