Project description:The goal of this analysis is to compare the transcriptome profile (RNA-seq) along different developmental ages in the naked mole rat ovary
Project description:Deep sequencing of mRNA from naked mole rat Analysis of ploy(A)+ RNA of different specimens: brain, kidney, liver from new born , 4 years old , 20 years old and 4 years old hypoxia-exposed naked mole rat
Project description:Heathly naked mole-rats kept under normal housing conditions harbor either a small or enlarged spleen. The aim of the study is to compare RNAseq of naked mole-rat (NM-R) small and enlarged spleens between them and to compare them with RNAseq of mouse spleen.
Project description:This study compares the transcriptional response to hypoxia in liver of the hypoxia-tolerant naked mole rat (NMR) and the hypoxia-sensitive rat.
Project description:Abundant high molecular weight hyaluronic acid (HMW-HA) contributes to cancer resistance and possibly longevity of the longest-lived rodent, the naked mole-rat1,2. To study whether the benefits of increased HMW-HA could be transferred to other animal species, we generated a transgenic mouse overexpressing naked mole-rat hyaluronic acid synthase 2 gene (nmrHAS2). nmrHAS2 mice showed increase in hyaluronan levels in several tissues, and lower incidence of spontaneous and induced cancer, extended lifespan and improved healthspan. The transcriptome signature of nmrHAS2 mice shifted towards that of longer-lived species. The most striking change observed in nmrHAS2 mice was attenuated inflammation across multiple tissues. HMW-HA reduced inflammation via several pathways including direct immunoregulatory effect on immune cells, protection from oxidative stress, and improved gut barrier function during aging. These findings demonstrate that the longevity mechanism that evolved in the naked mole-rat can be exploited to other species, and open new avenues for using HMW-HA to improve lifespan and healthspan
