Overexpression of Acid Ceramidase Protects from Tumor Necrosis Factor–Induced Cell Death

Tumor necrosis factor (TNF) signals cell death and simultaneously induces generation of ceramide. To evaluate the contribution of ceramide to TNF-dependent cell death, we generated clones of the TNF-sensitive cell line L929 that constitutively overexpress human acid ceramidase (AC). Ceramidase, in concert with sphingosine kinase, metabolizes ceramide to sphingosine-1-phosphate (SPP), an inducer...

The Death Domain Kinase RIP Protects Thymocytes from Tumor Necrosis Factor Receptor Type 2–induced Cell Death

Fas and the tumor necrosis factor receptor (TNFR)1 regulate the programmed cell death of lymphocytes. The death domain kinase, receptor interacting protein (rip), is recruited to the TNFR1 upon receptor activation. In vitro, rip-/- fibroblasts are sensitive to TNF-induced cell death due to an impaired nuclear factor kappaB response. Because rip-/- mice die at birth, we were unable to examine th...

Acid stress adaptation protects Sa acid-induced programmed cell death

In this work evidence is presented that acid stress adaptation protects Saccharomyces cerevisiae from acetic acid-mediated programmed cell death. Exponential-phase yeast cells, non-adapted or adapted to acid stress by 30 min incubation in rich medium set at pH 3.0 with HCl, have been exposed to increasing concentrations of acetic acid and time course changes of cell viability have been assessed...

Overexpression of Cytosolic Group IVA Phospholipase A2 Protects Cells from Ca2+-dependent Apoptotic Cell Death*

The calcium ionophore ionomycin induces apoptosis-like events in the human embryonic kidney (HEK) cell line at early times. Plasma membrane blebbing, mitochondrial depolarization, externalization of phosphatidylserine and nuclear permeability changes can all be observed within 15 min of treatment. However, there is no activation of caspases or chromatin condensation. Expression of a fusion prot...

Ischemia-induced up-regulation of heme oxygenase-1 protects from apoptotic cell death and tissue necrosis.

BACKGROUND Tissues are endowed with protective mechanisms to counteract chronic ischemia. Previous studies have demonstrated that endogenous heme oxygenase (HO)-1 may protect parenchymal tissue from inflammation- and reoxygenation-induced injury. Nothing is known, however, on whether endogenous HO-1 also plays a role in chronic ischemia to protect from development of tissue necrosis. The aim of...
