Prostate cancer possesses its unique feature of low proliferation rate and slow growth. Ca(2+)-induced apoptosis is not dependent on cell cycle progression and targeting this pathway could circumvent the problems encountered using current cytotoxic chemotherapies for prostate cancer. Hypoxia-inducible factor 1alpha (HIF-1alpha) is another novel cancer drug target and inhibitors of hypoxia-respo...

Apoptosis can be induced in response to hypoxia. The severity of hypoxia determines whether cells become apoptotic or adapt to hypoxia and survive. A hypoxic environment devoid of nutrients prevents the cell undergoing energy dependent apoptosis and cells become necrotic. Apoptosis regulatory proteins are delicately balanced. In solid tumours, hypoxia is a common phenomenon. Cells adapt to this...

The aim of the present study was to investigate hypoxia-induced apoptosis and autophagy in vascular smooth muscle cells (VSMCs) and the underlying molecular mechanisms of microRNA (miR)-17-5p responses in an anaerobic environment. The results revealed that miR-17-5p expression was significantly upregulated in VSMCs subjected to hypoxic conditions (P<0.05) and lower miR-17-5p levels were observe...

Tissue hypoxia occurs when local metabolism is disturbed by an imbalance between oxygen supply and consumption. In patients with chronic kidney disease, chronic hypoxia in the kidneys is the end result of multiple processes and mechanisms. Once established, however, accumulating evidence points to this chronic hypoxia as the central player and final common pathway to end-stage renal disease. Th...

Hypoxia-sensitive gene expression in the gastrocnemius muscle following chronic hind limb ischemia Andrew Tilton Chronic ischemia, caused by the formation atherosclerotic plaque occlusions in major conduit arteries, is the leading cause of morbidity and mortality in western societies. Vascular remodeling can help compensate for the adverse effects of atherosclerotic plaque formation. Vascular r...

Hypoxia in solid tumors is associated with the development of chemoresistance. Although many studies have focused on the effect of hypoxia on drug-induced apoptosis, the effect of nonapoptotic pathways on hypoxia-induced drug resistance has not been previously investigated. Here, we determined the effects of hypoxia on multiple forms of drug-induced death in human MDA-MB-231 breast carcinoma ce...
