Project description:We devised a systems biology approach to investigate the early host response to high-dose rectal SIV transmission, by transcriptomic comparative analysis of a natural reservoir host SIV model species, African green monkeys (AGMs – Chlorocebus sabaeus, N=28) and a pathogenic model, rhesus macaques (RMs - Macaca mulatta, N=24).on rectal tissues for both AGMs and RMs.

Project description:Aging of population is a great challenge of healthcare. In china, the number of the elderly is rapidly growing, and it was estimated that there will be approximately 400 million citizens above 65 years old in 2050.Study on the changes of brain during aging may help elucidate the mechanism of the pathological process, and hence prevent or treat these neurological diseases.Rhesus macaque (Macaca mulatta) and human have a genetic homology of 95%, and their anatomy structures or physiological process are highly similar, which make rhesus macaque one of the most important nonhuman primate models.Thus, the comparison between the change of protein profile during aging in human and rhesus macaque is still necessary, and the characteristics of proteins that are conservative or divergent are of interest.The aim of the(our) study is to identify the conservative changes of pathways during aging, and to reveal the potential difference between human and rhesus macaque so that relevant studies based on primate models can be interpreted more accurately.
Project description:Viral pneumonia has been frequently reported during early stages of influenza virus pandemics and in many human cases of highly pathogenic avian influenza (HPAI) H5N1 virus infection. To better understand the pathogenesis of this disease, we produced non-lethal viral pneumonia in rhesus macaques by using an HPAI H5N1 virus (A/Anhui/2/2005; referred to as Anhui/2). Infected macaques were monitored for 14 days, and tissue samples were collected at 6 time points for virologic, histopathologic and transcriptomic analyses. Thirteen colony-bred male or female rhesus macaques (Macaca mulatta), aged from 2.5 to 3.5 years and ranging in weight from 2.8 to 4.4 kg, were used for experiments. Twelve macaques were individually infected intratracheally with 10^7 EID50 of Anhui/2 in 4 ml of phosphate-buffered saline (PBS). At 6 h, 12 h, 1 d, 3 d, 6 d, and 14 d post-infection (p.i.), two animals per time-point were euthanized under anesthesia and necropsies were performed. Lung samples were collected and stored in RNAlater (Ambion, Austin, USA) at -80M-BM-0C for RNA analyses. The remaining macaque (mock-infected) was inoculated with 4 ml of PBS intratracheally and euthanized at 6 h p.i. Lung tissues from the mock-infected animal were collected and stored as described.
Project description:DNA methylation data from rhesus macaque (Macaca mulatta) profiled on the mammalian methylation array (HorvathMammalMethylChip40) which focuses on highly conserved CpGs across mammalian species. We profiled n = 283 tissue samples (blood, skin, adipose, kidney, liver, lung, muscle, and cerebral cortex)
Project description:We used the rhesus monkey (Macaca mulatta) as our animal model for the current study with two goals: to characterize the changes in histology and gene expression from early to late gestation (prenatal uterine organogenesis) and to determine if there are effects of prenatal exposure to bisphenol A (BPA) on the developing female uterus.

Project description:Diet studies of Taihangshan macaques (Macaca mulatta tcheliensis) in north China
Project description:We conducted a comprehensive transcriptome analysis of whole blood from male and female nonhuman primates (rhesus macaque (Macaca mulatta)) that received upper thoracic radiation. A Varian CLINAC 21EX linear accelerator was used (6 MV Linear Accelerator (Linac)). Body Weight Range: 3.5 to 5 kg (at initial physical exam). Age Range: 3 to 5 years (at initial physical exam).
Project description:MicroRNAs are small non-coding RNAs that are critical in post-transcriptional regulation. According to the latest miRBase (v22), there are 617 annotated pre-miRNAs in Macaca mulatta, which is much less than 1917 in human, although both of these two species are primates. To improve the annotation of miRNAs in Macaca mulatta, we generated 12 small RNA profiles from 8 tissues and perform comprehensive analysis of these profiles. We identified 613 conserved pre-miRNAs that have not been reported in Macaca mulatta and 25 novel miRNAs. Furthermore, we identified 996 editing sites with significant editing levels from 250 pre-miRNAs after analyzing the 12 self-generated and 58 additional published sRNA-seq profiles from different types of organs or tissues. Our results show that the distribution of different miRNA editing types in Macaca mulatta is different from that in human brains. Particularly, there are much more small indel events in miRNAs of Macaca mulatta than in human brains. These results significantly increase our understanding of miRNAs and their editing events in Macaca mulatta.
