... impairment and cell death were investigated in zebrafish. In vivo , exposure of 1 day post-fertilization (dpf) embryos to HEA only reduced the expression of the determined neuron marker neurod1 . In contrast, in 5 dpf larvae, HEA increased the expression of nes and sox2 , neural progenitor cell markers...

... of gastrovascular flow to the distal part of the stolon. High levels of endogenous H 2 O 2 and NO then accumulate in the regressing stolon. Remarkably, exogenous treatments with either H 2 O 2 or an NO donor equivalently trigger endogenous formation of both H 2 O 2 and NO. Cell death during regression is suggested...

... body cells, and we present evidence that these cells are eventually removed in the adult by a caspase cascade that leads to cell death. By genetically manipulating the lifespan of the larval fat cells, we demonstrate that these cells are nutritionally important during the early, non-feeding stage...

... the hypothesis that hyperthermia causes tendon cell death and results in tendon central core degeneration. Tendon fibroblasts cultured from the core of the equine SDFT were subjected to a temperature of 45 °C in an in vitro system for 0–180 min, and cell survival fraction was measured and compared...

... to become competent to respond to the peptide eclosion hormone. Eclosion hormone is then released and acts directly on these muscles to induce rapid cell death which is morphologically and physiologically distinct from steroid-regulated atrophy. * Current address : Department of Physiology...
