Abstract
AIM: To investigate the expression of hepatoma-derived growth factor (HDGF) in hepatocellular carcinoma (HCC) tissue and HepG2 cells and to analyze its significance.
METHODS: Ten HCC tissue samples and matched noncancerous tissue samples were collected. The mRNA expression of HDGF in these HCC samples, noncancerous tissue samples and HepG2 cells was detected by real-time RT-PCR. The protein expression of HDGF in 137 HCC tissue samples and 49 normal liver tissue samples was examined by immunohistochemistry. The relationship between HDGF expression and clinicopathological parameters in HCC was then analyzed.
RESULTS: The expression levels of HDGF mRNA were 21.11 and 11.39 times higher in HCC tissue and HepG2 cells than in noncancerous tissue, respectively. The positive rate of HDGF expression in HCC tissue was significantly higher than that in normal liver tissue (77.4% vs 51.5%, P = 0.011). High expression of HDGF protein was positively correlated with T classification, N classification and clinical stage (all P < 0.05) in HCC patients. Univariate Cox analysis showed that HDGF expression, N classification and clinical stage had significant correlation with survival prognosis of HCC patients (P = 0.028, 0.041 and 0.000; HR = 1.557, 1.526 and 2.316, respectively). Multivariate analysis showed that HDGF expression might be an independent prognostic indicator (P = 0.000, HR = 0.358) for the development and progression of HCC. Patients with higher HDGF expression showed a significantly shorter overall survival time than those with low HDGF expression.
CONCLUSION: HDGF is highly expressed in HCC tissue and HepG2 cells. High HDGF expression is an independent prognostic factor in HCC patients. High HDGF expression is associated with poor overall survival in patients with HCC.
