Project description:An Infinium microarray platform (GPL28271, HorvathMammalMethylChip40) was used to generate DNA methylation data from many tissues of 3 species of mole rats: Cape mole rat (Georychus capensis), Damaraland mole rat (Cryptomys damarensis), Naked mole rat (Heterocephalus glaber). We generated DNA methylation data from n=94 tissues from 3 species: Cryptomys damarensis (n=10), Georychus capensis (n=6), Heterocephalus glaber (n=78). All tissues ewere obtained from frozen tissue collection that were euthanized for other studies. Kidney (n=6), liver (n=61), skin (n=27). The tissues used in this study were obtained from post-mortem specimens from animals free from disease in compliance. Sample collection was from post-mortem material. Tissue samples were snap frozen in liquid nitrogen following dissection and transferred for storage at -80ºC. Genomic DNA was extracted using Qiagen DNeasy Blood and Tissue kit and quantified using Nanodrop and Qubit.als
Project description:We performed RNAseq, metabolomics and pathway enrichment analysis on cardiac tissue from naked mole-rats (Heterocephalus glaber) and from seven other members of African mole rat genera, Cape mole-rat (Georychus capensis), Cape dune mole-rat (Bathyergus suillus), Common mole-rat (Cryptomys hottentotus hottentotus), Natal mole-rat (C. h. natalenesis), Mahali mole rat (C. h. mahali), Highveld mole-rat (C. h. pretoriae) and Damaraland mole-rats (Fukomys damarensis) representing differing burrow and soil types, degrees of sociality, lifespan and hypoxia tolerance. In addition, we include the evolutionarily highly divergent hottentot golden mole (Ambysomus hottentotus), an Afrotherian subterranean, solitary mammal, and the C57/BL6 laboratory mouse as a standard mammal control. After RNA sequencing, we removed the reads mapped to rRNAs and get rawdata, then we filtered the low quality reads (More than 20% of the bases qualities are lower than 10), reads with adaptors and reads with unknown bases (N bases more than 5%) to get the clean reads. These are the data uploaded.
