1. Human 15-lipoxygenase-1 and telomerase gene expression in cancer and inflammation
Abstract : Human 15-lipoxygenase type 1 (15-LOX-1) is an enzyme that catalyzes the oxygenation of free or membrane-bond polyunsaturated fatty acids containing at least one bis-allylic methylene moiety. The enzyme has been proposed to be involved in various physiological and pathophysiological activities including inflammation, apoptosis, cell maturation and tumorigenesis. READ MORE
