Abstract


Hydroxybenzoate (HB) compounds have shown their significance in inducing apoptosis in primary chronic lymphocytic leukemia (CLL) and cancer cell lines, including HT-1080. The current study focuses on assessing the effects of 2-, 3- and 4-hydroxybenzoate calcium (HBCa) compounds on MCF-10A, MDA-MB231 and MCF-7 epithelial breast cell lines. The HBCa-treated cells were examined using annexin V, to measure apoptosis in the three epithelial breast cell lines, after 48 h of treatment. The results indicated that 0.5 and 2.5 mmol/L of HBCa induced cell death in a dose-dependent manner. The induction of cell death in normal MCF-10A cells was found to be significantly less (p= 0.0003–0.0068), in comparison to the malignant cell lines (MDA-MB231 and MCF-7). HBCa compounds were also found to cause cell cycle arrest in the epithelial breast cells at G1/G0. Furthermore, HBCa compounds induced the upregulation of apoptotic proteins (p53, p21, Bax and caspase-3), as well as the downregulation of the anti-apoptotic protein Bcl-2, which may suggest that apoptosis is induced via the intrinsic pathway.
