Treatment options for lung cancer include surgery, radiation therapy, chemotherapy, and targeted therapy, including Bortezomib, an FDA-approved boron-derived agent. To bring novel boron-containing compounds to the armamentarium of lung cancer therapy, this study aimed to unravel the anti-cancer potential of Boric Acid (BA) and Sodium pentaborate pentahydrate (NaB) on Non-Small Cell Lung Cancer cell line A549. According to the results, the survival rates of A549 cells decreased after BA and NaB treatments by 5.5-fold and 5.2-fold, respectively. The number of colony-forming units was reduced by 3-fold and 2.4-fold after BA and NaB treatments, respectively. Gene expressions and protein levels of some pro-apoptotic and tumor suppressor genes were upregulated and some anti-apoptotic genes were downregulated. Cell cycle arrest at the G2/M phase was detected after treatment with both boron. Proliferation markers Ki-67 and PCNA, and checkpoint regulators CDK1 and CDK2 gene expression levels were downregulated after BA and NaB treatments in the A549 cells. Our findings point to a promising selective anti-cancer activity of BA and NaB in the A549 cells without exerting any adverse effects on normal cells.
