T-cell acute lymphoblastic leukemia is characterized by its fast progression rate and high complications. TRAIL can be used to trigger apoptosis in cancer cells with minimal effects on normal cells, but most of cancer cells develop resistance to this agent through various mechanisms. HDAC inhibitors like SAHA can be used to make cancer cells more susceptible to TRAIL-induced apoptosis. In this study, this hypothesis was tested on MOLT-4 cancer cell line. The cells were divided into six groups including the control group, TRAIL 50 nM, TRAIL 100 nM, SAHA 2 μM, SAHA 2 μM + TRAIL 50 nM, and SAHA 2 μM + TRAIL 100 nM. Apoptosis was evaluated by flowcytometry after 24, 48 and 72 h. The expression levels of c-flip, DR4, DR5, CHOP, NF-κB, STAT3, Akt, and PI3K genes were investigated by quantitative real-time PCR. Data were analyzed using two-way variance analysis with Tukey's and Dunnett's multiple comparisons tests, and statistical significance was defined as having a p-value less than 0.05. Groups exposed to the combination of SAHA with TRAIL demonstrated the maximum apoptosis in MOLT-4 cells by increasing the expression of DR4, DR5, and CHOP and decreasing the expression of c-flip, STAT3, PI3k, Akt, and NF-kB genes. It can be concluded that SAHA increases the sensitivity of MOLT-4 cells to TRAIL-mediated apoptosis, which can be used as a strategy to overcome resistance to TRAIL in leukemic patients. • TRAIL resistance decreases MOLT4 cells apoptosis. • SAHA can overcome TRAIL resistance. • SAHA increases DR4 and DR5 expression in MOLT4 cells. • SAHA increases pro-apoptotic proteins in MOLT4 cells. • SAHA decreases anti-apoptotic proteins in MOLT4 cells.
