Synergism of a novel MCL‑1 downregulator, acriflavine, with navitoclax (ABT‑263) in triple‑negative breast cancer, lung adenocarcinoma and glioblastoma multiforme.

ABSTRACT: Myeloid cell leukemia sequence 1 (MCL‑1), an anti‑apoptotic B‑cell lymphoma 2 (BCL‑2) family molecule frequently amplified in various human cancer cells, is known to be critical for cancer cell survival. MCL‑1 has been recognized as a target molecule for cancer treatment. While various agents have emerged as potential MCL‑1 blockers, the present study presented acriflavine (ACF) as a novel MCL‑1 inhibitor in triple‑negative breast cancer (TNBC). Further evaluation of its treatment potential on lung adenocarcinoma and glioblastoma multiforme (GBM) was also investigated. The anticancer effect of ACF on TNBC cells was demonstrated when MDA‑MB‑231 and HS578T cells were treated with ACF. ACF significantly induced typical intrinsic apoptosis in TNBCs in a dose‑ and time‑dependent manner via MCL‑
