Abstract:

Natural products isolated from plant sources are well known for their pharmacological potential in diversity of disease treatments such as inflammatory or cancer conditions. Mango (Mangifera indica L.) and Juglans regia are thought to be rich of functional phytochemicals. To elucidate the anticancer activity of Juglans regia (JR) and Mangifera indica L (MI) aqueous extract were investigated on chronic lymphocytic leukemia (CLL) B lymphocytes and their mitochondria and the results were compared with those of normal B lymphocytes. Cellular parameters such as viability and caspase 3 activity, and mitochondrial parameters such as reactive oxygen species (ROS), mitochondria membrane potential (MMP), mitochondrial swelling and cytochrome c release were evaluated. Our results showed the extract of Mangifera indica L increased cytotoxicity and caspase 3 activation through mitochondria pathway only in CLL B lymphocytes and also the extract of Juglans regia not showed cytotoxicity and caspase 3 activation on CLL and healthy B lymphocytes. Our in vitro findings on isolated mitochondria showed that mitochondrial ROS formation, MMP collapse, and mitochondrial swelling and cytochrome c release were significantly (P < 0.05) increased after addition of Mangifera indica only in cancerous mitochondria. These results showed that Mangifera indica can act as a promising source for anti-cancer drug candidates by directly and selectively targeting mitochondria and inducing selective mitochondria mediated apoptosis on CLL B lymphocytes.

Cytotoxic effects of Mangifera indica L. kernel extract on human breast cancer (MCF-7 and MDA-MB-231 cell lines) and bioactive constituents in the crude extract

BACKGROUND Waterlily Mango (Mangifera indica L.) is thought to be antioxidant-rich, conferred by its functional phytochemicals. METHODS The potential anticancer effects of the ethanolic kernel extract on breast cancer cells (MDA-MB-231 and MCF-7) using MTT, anti-proliferation, neutral red (NR) uptake and lactate dehydrogenase (LDH) release assays were evaluated. Cytological studies on the bre...

Inhibitory effect of walnut (Juglans regia L.) husk hydroalcoholic extract on LDL oxidation in Vitro

Introduction: Lipid oxidation, including LDL oxidation, plays a pivotal role in development of atherosclerosis. Supplementing diet with antioxidants, such as vitamin E and walnut husk hydroalcoholic extract, may prevent LDL oxidation. In the present study, we investigated the in vitro effects of walnut husk hydroalcoholic extract on serum LDL oxidation caused by copper sulfate. Method: Blood sa...
