Reactive Oxygen Species Mediate Caspase Activation and Apoptosis Induced by Lipoic Acid in Human Lung Epithelial Cancer Cells through Bcl-2 Down-Regulation

The antioxidant a-lipoic acid (LA) is a naturally occurring compound that has been shown to possess promising anticancer activity because of its ability to preferentially induce apoptosis and inhibit proliferation…

α-lipoic acid induces apoptosis in human colon cancer cells by increasing mitochondrial respiration with a concomitant O2−.-generation

Abstract  The antioxidant a-lipoic acid (ALA) has been shown to affect a variety of biological processes associated with oxidative stress including cancer. We determined in HT-29 human colon cancer cells…

Dietary [alpha]-lipoic acid supplementation lowers blood pressure in spontaneously hypertensive rats

Background and objectives: In spontaneously hypertensive rats (SHRs), excess endogenous aldehydes bind sulfhydryl groups of membrane proteins, altering membrane Ca2+ channels and increasing cytosolic free calcium and blood pressure. The…

Restoration of functional defects in peripheral blood mononuclear cells isolated from cancer patients by thiol antioxidants alpha-lipoic acid and N-acetyl cysteine

Abstract The ability of Alpha-Lipoic Acid (ALA) and N-Acetyl Cysteine (NAC), two active antioxidant agents, to correct in vitro the most significant functional defects of peripheral blood mononuclear cells (PBMC)…
