The antiproliferative effect of Moringa oleifera crude aqueous leaf extract on cancerous human alveolar epithelial cells.

ABSTRACT:

Background

The incidence of lung cancer is expected to increase due to increases in exposure to airborne pollutants and cigarette smoke. Moringa oleifera (MO), a medicinal plant found mainly in Asia and South Africa is used in the traditional treatment of various ailments including cancer. This study investigated the antiproliferative effect of MO leaf extract (MOE) in cancerous A549 lung cells.

Methods

A crude aqueous leaf extract was prepared and the cells were treated with 166.7 μg/ml MOE (IC50) for 24 h and assayed for oxidative stress (TBARS and Glutathione assays), DNA fragmentation (comet assay) and caspase (3/7 and 9) activity. In addition, the expression of Nrf2, p53, Smac/DIABLO and PARP-1 was determined by Western blotting. The mRNA expression of Nrf2 and p53 was
