Increased nuclear envelope permeability and Pep4p-dependent degradation of nucleoporins during hydrogen peroxide-induced cell death.
The death of yeast treated with hydrogen peroxide (H(2)O(2)) shares a number of morphological and biochemical features with mammalian apoptosis. In this study, we report that the permeability of yeast nuclear envelopes (NE) increased during H(2)O(2)-induced cell death. Similar phenomena have been observed during apoptosis in mammalian tissue culture cells. Increased NE permeability in yeast was...
متن کاملNitric oxide and protein S-nitrosylation are integral to hydrogen peroxide-induced leaf cell death in rice.
Nitric oxide (NO) is a key redox-active, small molecule involved in various aspects of plant growth and development. Here, we report the identification of an NO accumulation mutant, nitric oxide excess1 (noe1), in rice (Oryza sativa), the isolation of the corresponding gene, and the analysis of its role in NO-mediated leaf cell death. Map-based cloning revealed that NOE1 encoded a rice catalase...
متن کاملNF-κB Potentiates Caspase Independent Hydrogen Peroxide Induced Cell Death
BACKGROUND The pro-survival activity of NF-κB in response to a variety of stimuli has been extensively characterized. Although there have been a few reports addressing the pro-cell death role of NF-κB, the precise mechanism of NF-κB's pro-cell death function still remains elusive. METHODOLOGY/PRINCIPAL FINDINGS In the present study, we investigated the role of NF-κB in cell death induced by c...
متن کاملNitric oxide counteracts the senescence of rice leaves induced by hydrogen peroxide
In the present study, we evaluate the protective effect of nitric oxide (NO) against the senescence of rice leaves promoted by hydrogen peroxide (H 2 O 2 ). Senescence of rice leaves was determined by decreases in protein content. H 2 O 2 treatment resulted in (1) increases in leaf H 2 O 2 content, (2) induction of leaf senescence, (3) increases in lipid peroxidation, (4) decreases in ascorbic ...
متن کاملHydrogen peroxide induced cell death: One or two modes of action?
Imlay and Linn show that exposure of logarithmically growing Escherichia coli to hydrogen peroxide (H2O2) leads to two kinetically distinguishable modes of cell killing. Mode one killing is pronounced near 1 mM concentration of H2O2 and is caused by DNA damage, whereas mode-two killing requires higher concentration ([Formula: see text]). The second mode seems to be essentially due to damage to ...
