BCAT2 binding to PCBP1 regulates the PI3K/AKT signaling pathway to inhibit autophagy-related apoptosis and ferroptosis in prostate cancer.

ABSTRACT: Prostate cancer (PCa) has emerged as a predominant cause of cancer-related mortality among men globally. The mechanisms of branched-chain amino acids (BCAAs) contributing to the development of PCa remain inadequately elucidated. The objective of this study was to examine the involvement of BCAAs and BCAT2 in tumorigenesis. BCAAs exhibited elevated expression levels in PCa tissues and cells. Among the critical enzymes involved in the BCAA metabolic pathway, only BCAT2 demonstrated significant expression in PCa and was closely associated with tumor progression and patient prognosis. RNA sequencing along with related functional experiments indicated that BCAT2 can inhibit autophagy, autophagy-related apoptosis, and ferroptosis in PCa. Furthermore, the results of co-immunoprecipitation, mass s
