Results presented in Figures 4 and 5 revealed that induction of CYP2E1 reduced the migration capacity whereas silencing of this CYP450 isoenzyme increased the number of MCF7 and MDA-MB-231 cells migrating within the gap indicating that CYP2E1 is potentially involved in the regulation of the migratory capacity of breast cancer cells. Here, CYP2E1 is linked to breast carcinoma.
