Abstract
Cuproptosis is a novel form of programmed cell death. The role and mechanism of cuproptosis-related genes in prostate adenocarcinoma have not been fully understood. In this study, a series of bioinformatic analyses were performed. Consequently, glycine cleavage system protein H with high expression and unfavorable prognosis was regarded as the most potential cuproptosis-related gene in prostate adenocarcinoma. Moreover, glycine cleavage system protein H might be a promising indicator for predicting leuprolide sensitivity in prostate adenocarcinoma and three potential drugs targeting glycine cleavage system protein H were identified. Enrichment analysis revealed that glycine cleavage system protein H-correlated genes were significantly enriched in tricarboxylic acid cycle-related pathways. Subsequently, small nucleolar RNA host gene 17/miR-29a-3p axis was found to partially account for overexpression of glycine cleavage system protein H in prostate adenocarcinoma. Collectively, the current study elucidated a potential cuproptosis-related competing endogenous RNA axis small nucleolar RNA host gene 17/miR-29a-3p/glycine cleavage system protein H in prostate adenocarcinoma.
