Establishment of monkey imprinted differentially methylated regions map by comparative analysis of parthenogenetic haploid embryonic stem cells and sperms

Project description:Genomic imprinting is a important biological process, which leads to parental specific gene expressions. Improper gene imprinting results in several developmental abnormalities, cancer and other diseases. Studies in mice indicated genomic imprinting establishment relied on parental allele-specific DNA methylation during gametogenesis. Despite the fact that genomic imprinting is highly conserved in mammalian, the species specific pattern exists. Until now, except that of in mouse, informations about imprinting patterns is little, especially in primates. Through generation genome-wide 5mC and 5hmC profiles for two types of haploid genomes from rhesus monkeys, including parthenogenetic haploid ESCs ( PG ha ESCs) (derived from rhesus monkey parthenogenetic embryos) and sperms. We clearly characterized and distinguished methylome (5mC) from hydroxymethylome (5hmC)(which can not discriminate from methylome in traditional bisulfite (BS) sequencing) in haploid genomes. Based on these information, we determined distribution patterns of 5mC and 5hmC in ha ESCs and sperms. Interestingly, both 5hmC levels and distribution patterns were similar in ha ESCs and sperms, and 5hmC which is enriched in the regions with low 5mC frequency. Meanwhile through comparing DNA methylation and hydroxymethylation status between sperms and ha ESCs, we first provided a fundamental information of monkey imprinted differentially methylated regions (DMRs) distribution in monkey chromosomes. Second, we observed that DMRs did not overlap with hydroxymethylated regions (DMR or DhMR), suggesting that establishment of imprinted regions was not interfered by 5hmC. Our results demonstrate DNA methylation profiling of PG ha ESCs and sperms can be uesed as a powerful and effective method to map and characterize imprinted regions in non-human primates genome.

mRNA expression data from human parthenogenetic haploid ESCs (hPGES), normal ESCs (H9) and human fibroblast

Project description:Here we report the derivation of human haploid ESCs from parthenogenetic haploid embryos. We used RNA-seq to compare the gene expression levels among human parthenogenetic haploid ESCs (hPGES), normal human ESCs (H9) and human forskin fibroblasts and identified that these cells express conventional ESCs pluripotent markers and most maternally imprinted genes were down-regulated.

Project description:Aging is a major risk factor for various forms of disease. An enhanced understanding of the physiological mechanisms related to aging is urgently needed. Nonhuman primates (NHPs) have the closest genetic relationship to humans, making them an ideal model to explore the complicated aging process. Multiomics analysis of NHP peripheral blood offers a promising approach to evaluate new therapies and biomarkers. Here, we explored the mechanisms of aging using proteomics (serum and serum-derived exosomes [SDEs]) in rhesus monkey (Macaca mulatta) blood.

Discovery of novel imprinted genes by transcriptional analysis of parthenogenetic embryonic stem cells

Project description:Parthenogenetic embryonic stem cells (PESCs) may have future utility in cell replacement therapies. We examined genome-wide mRNA expression profiles of monkey PESCs relative to ESCs derived from fertilized embryos. Several known paternally-imprinted genes were in the highly down-regulated group in PESCs compared to ESCs. Allele specific expression analysis of paternally-imprinted genes, i.e., those genes whose expression is down-regulated in PESCs, led to the identification of one novel candidate that was exclusively expressed from a paternal allele. Our findings suggest that PESCs could be used as a model for studying genomic imprinting and in the discovery of novel imprinted genes. Keywords: gene expression The transcriptomes of rhesus monkey embryonic stem cell lines derived from IVF-produced embryos (Oregon Rhesus Macaque Embryonic Stem, ORMES-22) were compared with rhesus monkey parthenogenetic embryonic stem cell lines (heterozygous rhesus Parthenogenetic embryonic stem cell lines, rPESC-2) and homozygous rhesus Parthenogenetic embryonic stem cell lines, ORMES-9). Moreover, the transcriptomes of rPESC-2 line were also compared with ORMES-9. Finally, the adult somatic skin fibroblasts were analyzed. Three biological replicates of each cell line (A, B, C) were analyzed.
