FBLN2 and hepatocellular carcinoma: Literature has reported that an upregulated FBLN2 is discovered in HCC samples, which is validated in our research.21 Depending on the date of HccDB database and HPRD database, previous studies hypothesized FBLN2 is related with poorer prognosis of HCC patients19 and may contribute to apoptosis in HCC.20 In view of the limited experimental research data on FBLN2 in HCC, we investigated the effect of FBLN2 in HCC and provided testable evident for previous hypotheses.
