Home” Antiaging” Understanding Why Mole Rats Live Five Times Longer Than Expected
The mole rat lives about 37 years which has to do with 5 times longer than anticipated for an animal of its size and type. Scientists at the Queen Mary University of London have actually discovered more about why the mole rat lives so long.
The mole rat have less cardiac arrest. The mole rat adaptions to low oxygen environments is assists secure their hearts. Human are susceptible to heart injury by hypoxia and anoxia triggered by blood occlusion throughout cardiac arrest. The naked mole rat heart prevents low oxygen damage.
Nature Communications– Naked mole-rats have unique cardiometabolic and hereditary adjustments to their underground low-oxygen way of lives.
The naked mole-rat Heterocephalus glaber is a eusocial mammal showing severe durability (37-year life expectancy), remarkable resistance to hypoxia and lack of heart disease. To recognize the systems behind these extraordinary qualities, metabolomics and RNAseq of heart tissue from naked mole-rats was compared to other African mole-rat genera (Cape, Cape dune, Common, Natal, Mahali, Highveld and Damaraland mole-rats) and evolutionarily divergent mammals (Hottentot golden mole and C57/BL6 mouse). We determine metabolic and hereditary adjustments distinct to naked mole-rats consisting of raised glycogen, therefore making it possible for glycolytic ATP generation throughout heart anemia. Raised normoxic expression of HIF-1α is observed while downstream hypoxia responsive-genes are down-regulated, recommending adjustment to low oxygen environments. Naked mole-rat hearts reveal minimized succinate levels throughout anemia compared to C57/BL6 mouse and minimal tissue damage following ischemia-reperfusion injury. These evolutionary characteristics show adjustment to a distinct hypoxic and eusocial way of life that jointly might add to their durability and health period.
