CYP11A1 and colorectal cancer: Other members of the CYP family appeared to be influenced by both AFB1 and BEN co-treatment; for example, CYP2U1 and CYP2W1, two genes highly expressed in colorectal cancer [75,76,77]—CYP11A1, involved in steroidogenesis and down-regulated by zearalenone in porcine Leydig cells [78]; CYP8B1, a gene coding for a key enzyme in bile acids synthesis [79].
