BRAF and hepatocellular carcinoma: To determine the synergistic role of NRF2 MTs together with oncogenic BRAF in HCC development, we overexpressed a 3xARE luciferase construct (which is sensitive to NRF2-mediated transactivation) along with NRF2 WT and MTs (D29A and L30F) and BRAF WT and BRAF V600E MT in Hepa1-6 cells.
