HNRNPA2B1 and hepatocellular carcinoma: miR503HG was also found to promote the degradation of the heterogeneous nuclear ribonucleoprotein A2/B1 (HNRNPA2B1) by ubiquitination and subsequent proteasomal degradation, which consequently led to the destabilization of p52 and p65 transcripts and ultimately suppressed NF-κB signaling in HCC.
