DNA repair in species with extreme lifespan differences

ABSTRACT: We compared RNA-seq expression patterns in liver, an organ with high oxidative metabolism and abundant spontaneous DNA damage, from humans, naked mole rats, and mice, differing in maximum lifespan over a range of ~100, 30, and 3 years, respectively, for 130 genes involved in DNA repair. The results show that the longer-lived species, human and naked mole rat, share higher expression of these DNA repair genes, including core genes in several DNA repair pathways. A more systematic approach of signaling pathway analysis (SPA) indicates statistically significant upregulation of several DNA repair signaling pathways in human and naked mole rat compared with mouse.

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. Analysis of 2 mRNA samples, one pooled from 3 wild-type mice liver tissue and another pooled from 3 naked mole-rat liver tissue.

Bulk RNA-seq datasets of co-injected naked mole rat and human fibroblasts to NSG mice 2022

Project description:To study the tumour-suppressive capabilities of naked mole-rat fibroblasts we subcutaneously co-injected the fibroblasts and human squamous carcinoma cells into the flanks of NSG mice, which lack mature T cells. As controls, we (1) performed the co-injection experiment with mouse fibroblasts, and (2) performed experiments in which we injected human squamous carcinoma cells without mouse or naked mole-rat fibroblasts. To determine how the co-injections with mouse or naked mole-rat fibroblasts affected tumour growth in vivo, we then transcriptionally profiled the human skin tumours.

Increased hyaluronan by naked mole-rat HAS2 improves healthspan in mice [microbiome]

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.
