Endoplasmic Reticulum Stress Inhibits AR Expression via the PERK/eIF2α/ATF4 Pathway in Luminal Androgen Receptor Triple-Negative Breast Cancer and Prostate Cancer

Investigators demonstrated that endoplasmic reticulum stress could decrease androgen receptor mRNA and protein levels via PERK/eIF2α/ATF4 signaling in luminal androgen receptor TNBC and prostate cancer.
