PSMC2 and cancer: Silencing of another proteasome subunit, proteasome 26S subunit ATPase (PSMC2), remarkably reduced hepatocellular (Liu et al., 2021), prostate (Liu et al., 2021), breast (Wang et al., 2021), and gastric (Liu et al., 2022) cancers viability, migration and invasion capacity, while promoting cell-cycle arrest and consequently apoptosis in these cell lines.
