PPM1A up-regulation inhibits TRIM52-mediated enhancement of MHCC-97L cell proliferation, invasion and migration. After transfection of MHCC-97L cells with pLVX-Puro-PPM1A or pLVX-Puro (Vector), PPM1A expression was measured by qRT-PCR (a) and Western blot analysis (b, c). After transfection of MHCC-97L cells with pLVX-Puro-TRIM52 or pLVX-Puro (Vector) in the absence or presence of pLVX-Puro-PPM1A transfection, the cell proliferation was measured by CCK-8 assay (d), the cell migration and invasion was measured by Transwell assay (e, f), and the expression of p21, MMP2, PPM1A, p-Smad2/3 and Smad2/3 was measured by Western blot analysis (g, h). Scale bars: 100 μm. **P < 0.01 compared with corresponding Vector. ^§§P <0.01 compared with TRIM52. ^##P < 0.01 compared with TRIM52
