RNA sequencing reveals differential expression of mitochondrial and oxidation reduction genes in the long-lived naked mole-rat when compared to mice.

Project description:The goal was to find genes which are differentially expressed between the naked mole-rat (Heterocephalus glaber) and the wild-type mice liver tissue. The genes which are most differentially expressed may provide a clue for the remarkable differences between naked mole-rat and mouse in terms of longevity, cancer resistance and adaptation to subterranean environments.

Methylation studies in mole rats. Part 2

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

Transcriptomes of subterranean mammals reveal that naked mole rats have distinctive cardiometabolic and genetic adaptations to their underground low-oxygen lifestyles

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.

Transformation of Naked Mole-Rat Cells

Project description:The naked mole-rat (NMR), Heterocephalus glaber, is a mouse-sized subterranean rodent native to East Africa. Research on NMRs is intensifying in an effort to gain leverage from their unusual physiology, long-life span and cancer resistance for the development of new theraputics. Few studies have attempted to explain the reasons behind the NMR’s cancer resistance, but most prominently Tian et al. reported that NMR cells produce high-molecular weight hyaluronan as a potential cause for the NMR’s cancer resistance. Tian et al. have shown that NMR cells are resistant to transformation by SV40 Large T Antigen (SV40LT) and oncogenic HRAS (HRASG12V), a combination of oncogenes sufficient to transform mouse and rat fibroblasts. We have developed a number of lentiviral vectors to deliver both these oncogenes and generated 106 different cell lines from five different tissues and eleven different NMRs, and report here that contrary to Tian et al.’s observation, NMR cells are susceptible to oncogenic transformation by SV40LT and HRASG12V. Our data thus point to a non-cell autonomous mechanism underlying the remarkable cancer resistance of NMRs. Identifying these non-cell autonomous mechanisms could have significant implications on our understanding of human cancer development.

Age-associated changes in the skin transcriptome in Naked mole-rats

Project description:Naked mole rats (NMRs, Heterocephalus glaber) are long-lived mammals that possess a natural resistance to cancer and other age-related pathologies, maintaining a healthy life span for >30 years. We report application of RNAseq technology to analyze changes in the skin transcriptome of NMRs during aging. RNAseq analyses reveal that the transcript levels of several longevity-associated (Igfbp3, Igf2bp3, Ing2) and tumor-suppressor genes (Btg2, Cdkn1a, Cdkn2c, Dnmt3a, Hic1, Socs3, Sfrp1, Sfrp5, Thbs1, Tsc1, Zfp36) are increased in aged versus young NMR skin. Overall, these data suggest that specific features in the NMR skin aging transcriptome might contribute to the resistance of NMRs to spontaneous skin carcinogenesis and provide a platform for further investigations of NMRs as a model organism for studying the biology and disease resistance of human skin.

Single-cell RNA (10X Chromium) of naked mole rate DMBA/TPA treated or control back skin and matched livers (CRUK B) 2022

Project description:We generated single cell transcriptomes from full thickness skin biopsies in naked mole-rat to quantify the skin cell types found in this species (control samples). To study if and how naked mole-rat skin changes upon exposure to a carcinogen, we performed a classical two-stage skin carcinogenesis experiment traditionally performed in mice, wherein cancer is initiated by a single application of 7,12-dimethylbenz[a]-anthracene (DMBA) followed by repeated treatment with 12-O-tetradecanoylphorbol-13-acetate (TPA) to drive cell proliferation. After 12 weeks, full thickness skin biopsies were collected and used to generate single cell transcriptomes (treatment samples).
