... and polyploid vertebrates. Indeed, polyploidization causes a huge stress for in terms of cell physiology and alters spermatogenesis in polyploid fish. The most extensively studied mode of germ cell death during spermatogenesis in vertebrates is apoptosis. The aim of this study was to examine caspase-3...

...Michiaki Yamashita; Nanami Mizusawa; Misako Hojo; Takeshi Yabu SUMMARY The pro-apoptotic caspase-3 gene has been shown to have key functions in the execution of apoptosis (programmed cell death) in vertebrate cells. However, the central role of caspase-3 in morphogenesis during development remains...

...-end labelling (TUNEL), DNA fragmentation profiling (laddering) and an assay for caspase-3 activity. DD induced TUNEL positivity and DNA laddering, but not caspase-like activation, in copepod embryos spawned by females fed for 10-15 days the diatom diet Thalassiosira rotula Meunier ( in vivo ),or when...
