Specifically, HBx is able to increase the expression of miRNA 602, targeting the putative tumor suppressor Ras association domain family 1 isoform A (RASSF1A) [89]; miRNA-143, targeting fibronectin type III domain-containing 3B (FNDC3B) promoting hepatoma cell invasion, migration and tumor metastasis [90]; miRNA-29a and miR-148a, targeting phosphatase and tensin homolog (PTEN) and stimulating cell migration [91, 92]. This evidence concerns the gene FNDC3B and hepatocellular carcinoma.
