PJA2 Suppresses Colorectal Cancer Progression by Controlling HDAC2 Degradation and Stability.

ABSTRACT: PJA2 is documented to degrade various substrates. Nevertheless, the role of PJA2 as an E3 ubiquitin-protein ligase in colorectal cancer (CRC) progression remains unexplored. The correlation between PJA2 mRNA levels and clinical characteristics is investigated using data from The Cancer Genome Atlas (TCGA) database. Quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry (IHC) are utilized to evaluate PJA2 expression levels in CRC tissues. The biological functions of PJA2 are confirmed through colony formation assays and azoxymethane/dextran sulfate sodium (AOM/DSS) mouse model of CRC, among other experimental approaches. The underlying molecular mechanisms of PJA2 action are elucidated using RNA sequencing (RNA-seq), co-immunoprecipitation (co-IP), proximity lig
