Knockdown of both NAP1L5 and MYH9 and downregulation of MYH9 genes in MHCC97H cells weakened the ability to promote phosphorylation of AKT and mTOR formed by low expression of NAP1L5 (Figure 8D) and restored the enhanced proliferation, migration and invasion of HCC cells (Figure 8E–8G). This evidence concerns the gene MYH9 and hepatocellular carcinoma.
