Anti-angiogenic effect of the combination of low-dose sorafenib and EGCG in HCC-induced Wistar rats

Publication Date Nov 21, 2022

Abstract

Background:  Sorafenib is a standard drug used for advanced hepatocellular carcinoma but is often resistant and toxic. Its combination with epigallo-3-catechin gallate leads to reduced resistance and toxicity but an equally effective anti-angiogenic effect.Therefore, this study aims to assess the anti-angiogenic effect of standard-dose Sorafenib compared to the combination of low-dose Sorafenib and epigallo-3-catechin gallate. Methods:  We conducted an animal study and double-blind, randomized controlled trials. A total of 25 male Wistar rats (7-weeks-old) were randomly divided into four groups, namely Sham (K), Control (O), a combination of low-dose Sorafenib and epigallo-3-catechin gallate group (X1), and standard-dose Sorafenib group (X2). All groups were injected with N-Nitrosodiethylamine 70 mg/kg body weight (BW) intraperitoneally for ten weeks, except the Sham group. After the development of hepatocellular carcinoma, X1 and X2 were treated for two weeks. Subsequently, liver tissues were examined for vascular endothelial growth factor (VEGF) level and microvascular density expression. Results: There was a significant difference (p=0.007) in the level of VEGF between group X1 (low dose Sorafenib + EGCG) and X2 (Standard dose Sorafenib). However, the differences in VEGF levels of group X1 and X2 compared to group O(Control) were significantly lower, with values p=0.000136 and p=0.019, respectively. The expression of microvascular density between groups X1 and X2  was not entirely different. Meanwhile, a significant diffe...
