Project description:Rhesus macaque is a prime model animal in neuroscience. A comprehensive transcriptomic and open chromatin atlas of the rhesus macaque brain is key to a deeper understanding of the brain. Here we characterize the transcriptome of 416 brain samples from 52 regions of 8 rhesus macaque brain. We identify gene modules associated with specific brain regions like the cerebral cortex, pituitary, and thalamus. In addition, we discover 9703 novel intergenic transcripts, including 1701 coding transcripts and 2845 lncRNAs. Most of the novel transcripts are only expressed in specific brain regions or cortical regions of specific individuals. We further survey the open chromatin regions in the hippocampal CA1 and several cerebral cortical regions of the rhesus macaque brain using ATAC-seq, revealing CA1- and cortex-specific open chromatin regions. Our results add to the growing body of knowledge regarding the baseline transcriptomic and open chromatin profiles in the brain of rhesus macaque.

Project description:The primary goal of this study was to compare the performances of Rhesus Macaque Genome Array and Human Genome U133 Plus 2.0 Array with respect to the detection of differential expressions when rhesus macaque RNA extracts were labeled and hybridized. The secondary goal of this study was to investigate the effect of mismatch position on signal strength in Affymetrix GeneChips by examining naturally occurring mismatches between rhesus macaque transcripts and human probes from Human Genome U133 Plus 2.0 Array.

Keywords: cross hybridization Rhesus macaque RNA from five sources (immortalized fibroblasts, cerebral cortex, pancreas, testes and thymus) was divided into two sets of aliquots of equal amount. Samples from each of the five sources were labeled and hybridized with either Rhesus Macaque Genome Array or two Human Genome U133 Plus 2.0 Array.

Project description:We search for developmental changes specific to humans by examining gene expression profiles in the human, chimpanzee and rhesus macaque prefrontal and cerebellar cortex. In both brain regions, developmental patterns were more evolved in humans than in chimpanzees. The major human specific genes in prefrontal cortex was enriched in neuronal functions and regulated by several transcription factors, which were previously implicated in regulation of neuronal functions. To confirm neuronal function of the human prefrontal cortex specific genes, we identifed response genes upon neuronal activation in mouse cortical neurons. Our results show that human specific genes are enriched in the response genes upon neuronal activation, implying the function of human prefrontal cortex specific genes in synaptic development.

The cortical neurons from E15 mouse were isolated and cultured. We then exposed neurons to bicuculline (Bic), or potassium chloride (KCl), or without treatment. The cultured neurons under each group were hybridized to Agilent whole mouse genome oligo microarray (4x44k).

Project description:Novel approaches were used to generate the DNA sequence information for the rhesus GeneChip (2005). The purpose of this experiment was to test its reliability and validity of the rhesus macaque GeneChip across different tissues and centers. Keywords: reliability To test the reliability of the rhesus GeneChip across different centers, RNA was isolated from five sources: cerebral cortex, pancreas, thymus, testis, and an immortalized fibroblast cell line. Aliquots of this RNA were sent to each of three centers: Yerkes National Primate Research Center, Oregon National Primate Research Center and the University of Nebraska Medical Center. Each center labeled the samples and hybridized them to two rhesus macaque GeneChips.

Project description:Purpose: To reveal the differences on epithelial cell composition, functional assignments and pharmacokinetics among mammals intestine, we use single cell sequencing to examine the conserved and divergent features among species, providing a cross-species single-cell transcriptomic atlases of ileal epithelium Methods:Alive ileum epithelial cells were sorted from two cynomolgus monkeys (14 years old). ScRNA-seq libraries were generated using the Chromium Single Cell 3’ Reagent Ki V3 (10X Genomics). The libraries were sequenced as paired-end with Illumina Novaseq 6000. Raw reads were aligned to the Mmul_10 Macaque genome, and Cell Ranger (v3.1.0) was used to estimate unique molecular identifiers (UMIs). Raw aligned features were loaded and processed using the Seurat package (v4.0.2). Low-quality cells were filtered if they expressed no more than 200 genes or with more than 20% of mitochondrial genes. Results: After cells with low information content and a high fraction of mitochondrial RNAs were excluded, 886 cells were analyzed. Conclusions: Eight cell types were identified in macaque ileum based on reported markers, including enterocytes, transient-amplifying (TA) cells, goblet cells, goblet progenitor cells, stem cells, enteroendorcine cells, CA7+ cells and tuft cells.
