Heat Shock Protein Family A Member 1A Attenuates Apoptosis and Oxidative Stress via ERK/JNK Pathway in Hyperplastic Prostate.

ABSTRACT: Benign prostatic hyperplasia (BPH) is a prevalent disorder in aging males. It is investigated whether heat shock protein family A member 1A (HSPA1A), a cytoprotective chaperone induced under stress, has been implicated in the development of BPH. RNA-sequencing and single-cell sequencing analyses revealed significant upregulation of HSPA1A in BPH compared to controls. In vitro experiments elucidated that HSPA1A was localized in prostatic epithelium and stroma, with upregulated expression in BPH tissues. Moreover, HSPA1A silencing augmented apoptosis and reactive oxygen species (ROS) accumulation, inhibiting proliferation via ERK/JNK activation, while overexpression reversed these effects in prostatic BPH-1 and WPMY-1 cells. Additionally, ERK1/2 suppression with U0126 rescued the effects of
