DNA fragmentation in mouse organs during endotoxic shock.
The systemic inflammatory response syndrome has still an unpredictable outcome, and patients often die of multiple organ failure despite circulatory stabilization therapy. The still incompletely understood pathophysiological mechanisms include organ damage due to direct toxic actions of cytokines elicited by overactivation of the host response. To study this process of organ failure in experime...
متن کامل[Letter to the Editor] DNA Fragmentation Is Not Associated with Apoptosis in Zerumbone-induced HepG2 Cells
Zerumbone is a cytotoxic compound isolated from the herbal plant, Zingiber zerumbet Smith, which exhibits antitumor activity [1-2], anti-inflammatory effects and possesses anti-proliferative potentials in a variety of cell lines [3-4]. DNA fragmentation indicates an early event of apoptosis leading to cell death due to the absence of new cellular proteins synthesizing for cell survival. Previou...
متن کاملSepsis induces DNA fragmentation in rat skeletal muscle.
Recent studies have demonstrated the activation of skeletal muscle DNA fragmentation in some catabolic conditions. In an attempt to elucidate if sepsis (a catabolic state) was also associated with muscle apoptosis, sepsis was induced by cecal ligation and puncture, and the results clearly show an induction of DNA fragmentation in gastrocnemius muscle following the induction of the septic state....
متن کاملCalcium-activated DNA fragmentation in rat liver nuclei.
Incubation of isolated rat liver nuclei with ATP, NAD+, and submicromolar Ca2+ concentrations resulted in extensive DNA hydrolysis. Half-maximal activity occurred with 200 nM Ca2+, and saturation of the process was observed with 1 microM Ca2+. ATP stimulated a calmodulin-dependent nuclear Ca2+ uptake system which apparently mediated endonuclease activation. Ca2+-activated DNA fragmentation was ...
متن کاملMethylmercury-induced sedimentation heterogeneity of T7 bacteriophage DNA.
Single-stranded and methylmercurated T7 DNA is composed of two species as evidenced from the sedimentation pattern displayed during band-sedimentation in self-generating density gradients as well as during equilibrium-sedimentation in CS2SO4 density gradients. Under the given experimental conditions, viz., at pH 9.18 and in presence of 0.1 mM CH3HgOH, the two species band in CS2SO4 with a densi...
