To understand its therapeutic efficacy on stem cell self renewal pathways, prevalence of CD44 positive cancer stem cell (CSC) population, expressions (mRNA/protein) of some key regulatory genes of self renewal Wnt and Hedgehog pathways along with expressions of E-cadherin and EGFR were analyzed during the liver carcinogenesis and in liver cancer cell line HepG2.
Mice lacking EGFR in macrophages show impaired hepatocarcinogenesis, whereas mice lacking EGFR in hepatocytes unexpectedly develop more HCC owing to increased hepatocyte damage and compensatory proliferation.
Eight single-nucleotide polymorphisms (SNPs), whose minor allele frequency >20% in the EGF and EGFR genes, were genotyped to examine their associations with hepatocarcinogenesis.
