Abstract:
Objective: To investigate the effect of curcumin on angiogenesis in rats with DEN (diethylnitrosamine)-induced HCC (hepatocellular carcinoma) under hypoxia. Methods: Rat HCC was induced by DEN, and its hepatic hypoxia model was established by ligating hepatic artery. The rats with established HCC model were randomly divided into four groups according to digital table method: lipiodol embolization group (group A), lipiodol combined with curcumin embolization group (group B), lipiodol combined with peripheral liver capsule group (group C), lipiodol combined with curcumin and peripheral liver capsule group (group D), with 10 rats in each group. VEGF expression in HCC cells and tissues, microvessel density (MVD), and median survival time (MST) of rats in each group were compared. Results: VEGF protein expression and microvessel density in group B, D were significantly lower than those in A group (P<0.01), while those in C group had no significant difference compared with group A (P >0.05). MST in group B, C and D was significantly longer than that in group A (P<0.05), and the MST in group D was higher than that in group B and C (P<0.05). Conclusion:Curcumin can inhibit tumor angiogenesis and decrease VEGF expression and MVD in HCC rats under hypoxia, thus further prolong the survival time of the rats.
