HNRNPK and gastric cancer: In addition, Liu et al. found that HNRNPK mRNA expression in infiltrating GC tissues was negatively correlated with miR-873-5p but positively correlated with CircVPS33B, while miR-873-5p inhibitor reversed the down-regulation of HNRNPK in GC cells with knockdown of Circ-VPS33B.
