Impact of caspase activation in human spermatozoa.
Caspases are central components in the apoptosis signaling cascade. The family of cysteine proteases transduces and enhances the apoptosis signal, and activation of effector caspases results in controlled cellular degradation. Although initially the presence of caspases in spermatozoa was controversially discussed in recent years, many studies demonstrated their activation in male germ cells. A...
متن کاملApoptotic threshold is lowered by p53 transactivation of caspase-6.
Little is known about how a cell's apoptotic threshold is controlled after exposure to chemotherapy, although the p53 tumor suppressor has been implicated. We identified executioner caspase-6 as a transcriptional target of p53. The mechanism involves DNA binding by p53 to the third intron of the caspase-6 gene and transactivation. A p53-dependent increase in procaspase-6 protein level allows fo...
متن کاملThalidomide inhibits activation of caspase-1.
Thalidomide is an efficient anti-inflammatory and anti-angiogenic drug, but its therapeutic use is problematic due to a strong teratogenic activity. Nevertheless, thalidomide was approved for the treatment of inflammatory skin diseases and certain types of cancer, and it is extensively tested for several other indications. Recently, we demonstrated that active caspase-1, whose activation is dep...
متن کاملCaspase activity and apoptotic markers in ejaculated human sperm.
The objectives of this study were to determine if human ejaculated sperm exhibit active caspases and if caspase-dependent apoptosis markers are identifiable. Sperm from fertile donors and infertile patients were examined after gradient separation into leukocyte-free fractions of high and low motility. Sperm were evaluated for motion parameters, morphology, caspase activation, and apoptosis mark...
متن کاملDual Role of Caspase-11 in Mediating Activation of Caspase-1 and Caspase-3 under Pathological Conditions
Caspase-11, a member of the murine caspase family, has been shown to be an upstream activator of caspase-1 in regulating cytokine maturation. We demonstrate here that in addition to its defect in cytokine maturation, caspase-11-deficient mice have a reduced number of apoptotic cells and a defect in caspase-3 activation after middle cerebral artery occlusion (MCAO), a mouse model of stroke. Reco...
