Project description:Embryonic stem cells (ESCs) may be able to cure or alleviate the symptoms of various degenerative diseases. However, unresolved issues regarding apoptosis, maintaining function and tumor formation mean a prudent approach should be taken towards advancing ESCs into human clinical trials. The rhesus monkey provides the ideal model organism for developing strategies to prevent immune rejection and test the feasibility, safety and efficacy of ESC-based medical treatments. Transcriptional profiling of rhesus ESCs provides a foundation for future pre-clinical ESC research using non-human primates as the model organism. In this research we use microarray, immunocytochemistry, real-time and standard RT-PCR to characterize and transcriptionally profile rhesus monkey embryonic stem cells. We identify 367 rhesus monkey stemness genes, we demonstrate the high level (>85%) of conservation of rhesus monkey stemness gene expression across five different rhesus monkey embryonic stem cell lines, we demonstrate that rhesus monkey ESC lines maintain a pluripotent undifferentiated state over a wide range of Pou5f1 (Oct-4) expression levels and we compare rhesus monkey, human and murine stemness genes to identify the key mammalian stemness genes. The supplementary tables list the genes that have been upregulated in each undifferentiated rhesus monkey embryonic stem cell line (GSM99998, GSM99999,GSM100000, GSM100001, GSM100002, GSM99965, GSM99966) in comparison analysis with the pooled differentiated embryonic stem cells (GSM99840). Supplemental Table 1 contains the comparison analysis for all 52,865 probe sets on the rhesus monkey gene chip, Supplemental Table 2 contains the rhesus monkey genes that were significantly upregulated (FC>3) in the ORMES-6 biological replicates, Supplemental Table 3 contains the rhesus monkey genes that were significantly upregulated (FC>3) in the pooled differentiated EBs and Supplemental Tables 4-8 represent genes that were significantly upregulated in ORMES 6A, 7, 9, 10 and 13 respectively. Supplemental Table 9 contains the RT-PCR primers used in this project. Keywords: Rhesus monkey embryonic stem cell microarray
Project description:Though the rhesus monkey is one of the most valuable non-human primate animal models for various human diseases because of its manageable size and genetic and proteomic similarities with humans, proteomic research using rhesus monkeys still remains challenging due to the lack of a complete protein sequence database and sufficient proteomic information. In this project, proteomic profiling of multiple organ tissues, 9 male and 11 female were performed in an automated, high-throughput manner employing annotated UniProtKB human database. Based on the success of this alternative interpretation of MS data, the list of proteins identified from total 12 organs of male and female subjects will benefit future rhesus monkey proteome research.
Project description:Thymus is the important immune organ, responsible for T cell development and differentiation.We conduct rhesus monkey thymus proteomics of FNC.
Project description:Rhesus Monkey is one of the important primate models widely used in the fields of disease mechanism study, pre-clinical test in drug discovery and molecular evolution. However, the majority of rhesus gene annotations were putatively mapped from human genome, with only 10% supported by rhesus EST data.So, to better study the transcriptome, paired-end, strand-specific, poly(A)-positive RNA-Seq were performed in 5 rhesus monkey tissues. 5 tissue samples examined: prefrontal cortex, liver, skeletal muscle, adipose, testis
Project description:We developed a simple, antibody-free approach for single shot analysis of tau phosphorylation across the entire protein by liquid-chromatography tandem mass spectrometry (LC-MS/MS) to study age-related changes in tau phosphorylation. This methodology is species independent; thus, while initially developed in a rodent model, we utilized this technique to analyze 36 phosphorylation sites on rhesus monkey tau from the prefrontal cortex (PFC), a region vulnerable to AD degeneration. We identified novel, age-related changes in tau phosphorylation in the rhesus monkey PFC and analyzed patterns of phosphorylation change across domains of the protein. We confirmed a significant increase and positive correlation with age of phosphorylated serine235 tau and phosphorylated serine396 tau levels in an expanded cohort of 14 monkeys.
Project description:Here we used rhesus monkey as an animal model and compared the endometrial miRNA expression profiles during early-secretory (day 15, pre-receptive) phase and mid-secretory (day 21, receptive) phase by deep sequencing. In order to facilitate the prediction of their target genes, the 3'-UTRome was also determined using tag sequencing of mRNA 3'-termini. Defining the microRNome and the 3'-UTRome in the endometrium of rhesus monkey.
Project description:Here, we describe the identification of circRNA in monkey (Rhesus macaque) skeletal muscle. RNA sequencing analysis was employed to identify and annotate ~12,000 circRNAs, including numerous circular intronic RNAs (ciRNAs), from monkey skeletal muscle tissue of various ages.
