Project description:mRNA-seq were conducted for iPS cells of human-1 (409-B2/HPS0076), human-2 (Nips-B2/HPS0223), chimpanzee-1 (kiku/0138F-1), and chimpanzee-2 (mari/0274F-2). To compare gene expression levels, the reads were first mapped to the chimpanzee genome (panTro5), and mapped reads were then mapped to the human genome (hg38). Gene expression was anlyzed based on the hg38 annotation.

Project description:We performed deep strand-specific sequencing of poly-adenylated RNA (polyA+ RNAseq) from human, chimpanzee, macaque and mouse tissues, with the goal of detecting numerous non-annotated poorly expressed and antisense genes. We identified thousands of annotated and novel genes, especially in testis. We discovered that ~2% of the human and chimpanzee multiexonic genes were specific from such species.

Project description:Small RNA-seq were conducted for iPS cells of human-1 (409-B2/HPS0076), human-2 (Nips-B2/HPS0223), chimpanzee-1 (kiku/0138F-1), and chimpanzee-2 (mari/0274F-2). The human samples were mapped to the human genome (hg38) and the chimpanzee samples were mapped to the chimpanzee genome (panTro5). The mapped reads for individual TE copies (in the repeatmasker tables downloaded from UCSC genome browser) were counted, and those for the same subfamily were summed up. The counts were normalized by RPM (reads per million genome-mapped reads).

Project description:We compared the genome-wide patterns of DNA methylation in the brains of humans to those of our closest evolutionary relative, chimpanzees, using base-pair resolution whole-genome methylation maps of the prefrontal cortex. Our data reveal that the prefrontal cortex is the most heavily methylated among the human tissues examined so far. Nevertheless, hundreds of genes exhibit dramatically reduced levels of promoter DNA methylation in the human brain relative to the chimpanzee brain. Many of these genes are associated with neurological disorders, psychological disorders, and cancers, and are enriched for functions related to cellular metabolic processes and protein binding. Moreover, the majority of these genes exhibit higher expression in the human brain compared to the chimpanzee brain.

Project description:Complete genome sequencing has identified millions of DNA changes that differ between humans and chimpanzees. Although a subset of these changes likely underlies important phenotypic differences between humans and chimpanzees, it is currently difficult to distinguish causal from incidental changes and to map specific phenotypes to particular genome locations. To facilitate further genetic study of human-chimpanzee divergence, we have generated human and chimpanzee auto-tetraploids and allo-tetraploids by fusing induced pluripotent stem cells (iPSCs) of each species. The resulting tetraploid iPSCs can be stably maintained and retain the ability to differentiate along ectoderm, mesoderm, and endoderm lineages. RNA sequencing identifies thousands of genes whose expression differs between humans and chimpanzees when assessed in single-species diploid or auto-tetraploid iPSCs. Analysis of gene expression patterns in inter-specific allo-tetraploid iPSCs shows that human-chimpanzee expression differences arise from substantial contributions of both cis-acting changes linked to the genes themselves, and trans-acting changes elsewhere in the genome. To enable further genetic mapping of species differences, we tested chemical treatments for stimulating genome-wide mitotic recombination between human and chimpanzee chromosomes, and CRISPR methods for inducing species-specific changes on particular chromosomes in allo-tetraploid cells. We successfully generated derivative cells with nested deletions or inter-specific recombination on the X chromosome. These studies identify a long distance cis-regulatory domain of the Fragile X-associated gene (FMR1), confirm an important role for the X chromosome in trans-regulation of other expression differences, and illustrate the potential of this system for more detailed mapping of the molecular basis of human and chimpanzee evolution.

Project description:We performed deep strand-specific sequencing of poly-adenylated RNA (polyA+ RNAseq) from human, chimpanzee, macaque and mouse tissues, with the goal of detecting numerous non-annotated poorly expressed and antisense genes. We identified thousands of annotated and novel genes, especially in testis. We discovered that ~2% of the human and chimpanzee multiexonic genes were specific from such species. We generated RNA-Seq data (∼2.10 billion paired-end reads, 25-100 bp length) for the polyadenylated RNA fraction of brain (cerebral cortex), heart, liver and testis. In human and chimpanzee, we generated 2 samples per tissue corresponding to different individuals. In macaque, only 1 sample per tissue was generated. In mouse, considered as the evolutionary outgroup, we generated three pools of brain samples, and one pool of heart, liver and testis samples. We generated an additional sample in Testis without including reverse transcriptase as a control of DNA contamination.

Project description:Genome wide DNA methylation profiling of brain and liver from human and chimpanzee. The Illumina HumanMethylation27 DNA Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs for each sample. Samples included liver and NeuN-positive/NeuN-negative/unsorted brain in three individuals from each of two species (human and chimpanzee).

Project description:A microarray analysis of whole-genome gene expression and single feature polymorphism in a (Populus trichocarpa X Populus deltoides) X Populus deltoides pseudo-backcross pedigree. Genetic variation in gene expression was quantified for 55,793 predicted gene models based on a single probe per gene. Concurrently, sequence-level polymorphism was analyzed based on dedicated probes identified in a pilot study comprised of the two parent genotypes (GPL7169). Resultant data contributed to a high density genetic map and to analysis of the genetic architecture of gene expression in Populus.
