Secondly, we constructed the lnc-SNHG3/hsa-miR-139-5p/MAP3K14 overexpression ceRNA network related to HCC prognosis, and further experimental studies are needed to investigate the role and mechanism of the lnc-SNHG3/MAP3K14 axis in HCC. This evidence concerns the gene SNHG3 and hepatocellular carcinoma.
