PPP2R5C and hepatocellular carcinoma: In the current study, we further used this recombinant plasmid (pTT5‐anti‐HBx) to verify that the production of intracellular anti‐HBx mAb could block HBx expression and its induced B56γ‐mediated dephosphorylation activity, which, in turn, could inhibit the HBV‐associated migration and invasion of HBx‐expressing HCC cells.
