Similar findings were observed in another study, in which incubation of Sg with CRC cell lines, such as HT29, Caco-2, SW480, and HCT116, increased the expression of CYP1A1 and the CSC marker, aldehyde dehydrogenase 1 (ALDH1) in an AhR-dependent manner [134]. This evidence concerns the gene CYP1A1 and colorectal carcinoma.
