In Vitro Inhibitory Effect of Succinic Acid on T-Cell Acute Lymphoblastic Leukemia Cell Lines.

BACKGROUND AND AIMS

Although several treatment regimens for T-cell acute lymphoblastic leukemia (T-ALL), trouble is still ongoing that relapse of disease after therapies in both pediatric and adult patients. Hence, the demand for new alternative therapeutics that are antiproliferative for cancer cells but do not harm healthy cells in treatments is increasing day by day. This study aimed to investigate whether succinic acid show anti-proliferative and apoptotic effect of on T-ALL cell lines.

METHODS

Time and dose-dependent effects of succinic acid on T-ALL cell lines were determined by using WST-1, caspase-3/ bicinchoninic acid (BCA), and Annexin V-Fluorescein isothiocyanate (FITC) assays. We included the MRC-5 cell line in our study as a healthy control group.

RESULTS

Based on our findings, 25 and 50 mmol dosages of succinic acid has shown an apoptotic effect on T-ALL cell lines for 48 h treatment. Also, it has shown that after 48 h exposure of 25 and 50 mmol dosages of succinic acid has no significant cytotoxic effect in healthy MRC-5 cells. Apoptotic activity of succinic acid on CCRF-CEM cell line was caspase-3 dependent but not for MOLT-4. As a consequence, succinic acid was found to effect for T-ALL treatment in vitro and might also enlighten new study fields for different cancer experiments.
