MET and hepatocellular carcinoma: To investigate whether induction of MET and AP-1 family genes by ATO is also observed in other hands, we used the mRNA expression array data in the hepatocellular carcinoma cell model HepG2 treated with different concentrations of ATO for 48 h (published by Hara-Yamamura et al. in 2013 at Gene Expression Omnibus database; Accession Nr: GSE48441 [24]) and analyzed them for the respective gene expression.
