A generally conserved response to hypoxia in iPSC-derived cardiomyocytes from humans and chimpanzees

Project description:Despite anatomical similarities, there are differences in susceptibility to cardiovascular disease (CVD) between primates; humans are prone to myocardial ischemia, while chimpanzees are prone to myocardial fibrosis. Induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) allow for direct inter-species comparisons of the gene regulatory response to CVD-relevant perturbations such as oxygen deprivation, a consequence of ischemia. To gain insight into the evolution of disease susceptibility, we characterized gene expression levels in iPSC-CMs in humans and chimpanzees, before and after hypoxia and re-oxygenation. The transcriptional response to hypoxia is generally conserved across species, yet we were able to identify hundreds of species-specific regulatory responses including in genes previously associated with CVD. The 1,920 genes that respond to hypoxia in both species are enriched for loss-of-function intolerant genes; but are depleted for expression quantitative trait loci and cardiovascular-related genes. Our results indicate that response to hypoxic stress is highly conserved in humans and chimpanzees.

Age-Associated Epigenetic Change in Chimpanzees and Humans

Project description:Genome wide DNA methylation profiling of captive chimpanzees of ages spanning the chimpanzee lifespan (whole blood) Methylation levels have been shown to change with age at sites across the human genome. Change at some of these sites is so consistent across individuals that it can be used as an “epigenetic clock” to predict an individual’s chronological age within a few years. Studies of age-related epigenetic change in other mammals, including mice, whales, and canids, show that some but not all of the same loci as in humans undergo age-associated methylation changes. An in-depth comparison of chimpanzees with humans is of interest because the two species are genetically similar but differ in lifespan. To this end, we profiled genome-wide blood methylation levels for 113 samples from 83 chimpanzees aged 1-58 years (26 chimpanzees were sampled at multiple ages during their lifespan). We used this data to build a chimpanzee-specific epigenetic clock model as well as to compare genome-wide patterns of change with age between humans and chimpanzees more generally.

A Comparative Assessment of iPSC Derived Cardiomyocytes with Heart Tissues in Humans and Chimpanzees

Project description:To study regulatory differences between species, the field of comparative primate genomics has used several approaches, including the use of post mortem frozen tissues, cell lines, and model organisms. However, there are limited quality cell lines from primates and post-mortem tissues cannot be staged, are not amenable to experimental perturbations and are often subject to high environmental variances. Inducible pluripotent stem cells (iPSCs) are an attractive system to study primate biology in a comparative context. However, the fidelity of iPSC derived cell types to primary tissues needs to be assayed in a comparative primate context before the utility of iPSCs can be fully realized for comparative genomics. In order to comprehensively benchmark the performance of iPSC model systems in a comparative framework, we collected RNA-sequencing from primary adult heart tissue and iPSC derived cardiomyocytes from multiple human and chimpanzee individuals. We identified the optimal parameters of iPSC differentiation into cardiomyocytes that minimized differences between each species and their respective adult tissue counterparts in a balanced manner across species. We found that iPSC derived cardiomyocytes are able to recapitulate 50% of the interspecies gene expression differences identified between human and chimpanzee in primary post mortem heart tissues. Furthermore, we determined that cultured cardiomyocytes appear more similar to adult hearts than any other single tissue in their ability to recapitulate differences in gene regulation between human and chimpanzee.

Gene expression in human vs chimpanzees

Project description:Despite the close evolutionary relationship and striking genetic similarity between humans and chimpanzees, there are remarkable differences in anatomy, behavior, and disease susceptibility in the two species. One step towards understanding the biological basis of these phenotypic differences is to characterize quantitative differences in levels of expression of genes in humans and chimpanzees. To contribute to such analysis, we compared gene expression patterns in lymphoblastoid cell lines between nine unrelated humans and ten unrelated chimpanzees by using human cDNA microarrays. Hybridizations to arrays containing 43,233 features produced high quality data for 22,879 cDNA clones, representing 20,266 Unigenes. We observed statistically significant differences in transcript levels for 32% of these genes (P < 0.05, Student t test), with about 200 cDNAs showing differences of more than 2-fold (lower bounds of 95% confidence interval). Among these are genes involved in cell surface glycosylation and responses to toxins and viruses. Examination of functional annotations for the differentially expressed genes revealed lower expression of cell cycle and energy pathways genes, and higher expression of chemokines, 26S proteasome and cell motility genes in chimpanzee samples. These genes and pathways could underlie some of the phenotypic differences between humans and chimpanzees. Keywords: other
