Exposure of MCF7 and MCF10A cells at low levels of AFB1 can induce modifications in the expression of key genes involved in cancer, cell cycle, apoptosis, and p53 pathways, as well as changes at the transcriptomic level of BRCA1/2, p53, HER1/2, cMYC, BCL2, MCL1, CCND1, WNT3A, MAPK1/2, DAPK1, and caspases 8/9 genes [180]. Here, MYC is linked to cancer.
