OBJECTIVES: The present study was aimed to explore the prognostic strength of Sox2 and
Oct4A in hepatocellular carcinoma (HCC). DESIGN AND METHODS: We investigated the
expression of Sox2 and Oct4A in five hepatoma cell lines, one immortalized normal liver cell
line, HCC tissues with matched nontumorous liver tissues and normal liver tissues by
reverse transcription-polymerase chain reaction. RESULTS: Sox2 and Oct4A mRNA were
overexpressed in hepatoma cell lines and tumor tissues. Sox2 or Oct4A positive expression …
OBJECTIVES
The present study was aimed to explore the prognostic strength of Sox2 and Oct4A in hepatocellular carcinoma (HCC).
DESIGN AND METHODS
We investigated the expression of Sox2 and Oct4A in five hepatoma cell lines, one immortalized normal liver cell line, HCC tissues with matched nontumorous liver tissues and normal liver tissues by reverse transcription-polymerase chain reaction.
RESULTS
Sox2 and Oct4A mRNA were overexpressed in hepatoma cell lines and tumor tissues. Sox2 or Oct4A positive expression was significantly associated with an aggressive phenotype. Both univariate and multivariate analyses revealed that Sox2 or Oct4A was an independent prognostic factor for HCC. When using subgroup analysis, the patients with a co-expression of Sox2/Oct4A had the poorest prognosis. Further analysis demonstrated that Sox2 alone or Sox2/Oct4A could stratify outcome in HCC patients with early stage.
CONCLUSIONS
Sox2 and Oct4A can be novel predictors of poor prognosis for patients undergoing resection of HCC.
