Maintained cardiac pumping in anoxic crucian carp.
Like most vertebrates, humans die within minutes when deprived of molecular oxygen (anoxia), in part because of cardiac failure. In contrast, some freshwater turtles can survive anoxia for months at low temperatures, but to do so, they drastically suppress cardiac activity and autonomic cardiovascular control. Although Carassius carassius, the crucian carp, shares this anoxia tolerance, we show...
متن کاملGenetic Distances of Crucian Carp Populations analyzed by PCR Approach
Genomic DNAs isolated from crucian carp of four rivers, belonging to the family Cyprinidae was amplified by seven oligonucleotides primers. In the present study, we employed hierarchical clustering method in order to reveal genetic distances and variations. Crucian carp was acquired from Hangang river (CAH), Geumgang river (CAG), Nakdonggang river (CAN) and Yeongsangang river (CAY). The primer ...
متن کاملThe psychoactive pollutant fluoxetine compromises antipredator behaviour in fish.
Pharmaceuticals are increasingly being detected in aquatic ecosystems worldwide. Particularly concerning are pharmaceutical pollutants that can adversely impact exposed wildlife, even at extremely low concentrations. One such contaminant is the widely prescribed antidepressant fluoxetine, which can disrupt neurotransmission and behavioural pathways in wildlife. Despite this, relatively limited ...
متن کاملCell proliferation and gill morphology in anoxic crucian carp.
Is DNA replication/cell proliferation in vertebrates possible during anoxia? The oxygen dependence of ribonucleotide reductase (RNR) could lead to a stop in DNA synthesis, thereby making anoxic DNA replication impossible. We have studied this question in an anoxia-tolerant vertebrate, the crucian carp (Carassius carassius), by examining 5'-bromo-2'-deoxyuridine incorporation and proliferating c...
متن کاملEvidence for recombination of mitochondrial DNA in triploid crucian carp.
In this study, we report the complete mitochondrial DNA (mtDNA) sequences of the allotetraploid and triploid crucian carp and compare the complete mtDNA sequences between the triploid crucian carp and its female parent Japanese crucian carp and between the triploid crucian carp and its male parent allotetraploid. Our results indicate that the complete mtDNA nucleotide identity (98%) between the...
