Ubiquitin-proteasome pathways have a crucial role in tumor progression. PSMD4 (Rpn10, 26S proteasome non-ATPase subunit 4), which is a subunit of the regulatory particle, is a major ubiquitin (Ub) receptor of 26S proteasome. PSMD4 overexpression has been observed in colon carcinoma, hepatocellular carcinoma, and breast cancer. In this work, we elucidated the effect of hypoxia on PSMD4 gene expression in prostate cancer cells (PC3). Chemically mimicked hypoxia drastically upregulated PSMD4 gene expression at both mRNA and protein levels. |
