Project description:Macaque species share over 93% genome homology with humans and develop many disease phenotypes similar to those of humans, making them valuable animal models for the study of human diseases (e.g.,HIV and neurodegenerative diseases). However, the quality of genome assembly and annotation for several macaque species lags behind the human genome effort. To close this gap and enhance functional genomics approaches, we employed a combination of de novo linked-read assembly and scaffolding using proximity ligation assay (HiC) to assemble the pig-tailed macaque (Macaca nemestrina) genome. This combinatorial method yielded large scaffolds at chromosome-level with a scaffold N50 of 127.5 Mb; the 23 largest scaffolds covered 90% of the entire genome. This assembly revealed large-scale rearrangements between pig-tailed macaque chromosomes 7, 12, and 13 and human chromosomes 2, 14, and 15. We subsequently annotated the genome using transcriptome and proteomics data from personalized induced pluripotent stem cells (iPSCs) derived from the same animal. Reconstruction of the evolutionary tree using whole genome annotation and orthologous comparisons among three macaque species, human and mouse genomes revealed extensive homology between human and pig-tailed macaques with regards to both pluripotent stem cell genes and innate immune gene pathways. Our results confirm that rhesus and cynomolgus macaques exhibit a closer evolutionary distance to each other than either species exhibits to humans or pig-tailed macaques. These findings demonstrate that pig-tailed macaques can serve as an excellent animal model for the study of many human diseases particularly with regards to pluripotency and innate immune pathways.

Project description:Our earlier studies in pig-tailed macaques demonstrated varying SHIV susceptibility during the menstrual cycle, likely caused by cyclic variations in immune responses in the female genital tract. There is concern that high-dose, long-lasting, injectable progestin-based contraception could mimic the luteal phase and predispose women to HIV-1 acquisition and transmission. In this study, we adopted a systems biology approach employing proteomics (tandem mass spectrometry), transcriptomics (RNA microarray hybridization), and other specific protein assays (enzyme-linked immunosorbent assays and multiplex chemokine-cytokine measurements) to characterize the effects of hormonal changes on the expression of innate factors and secreted proteins in the macaque vagina. Several antiviral factors and pathways (including acute phase response signaling and complement system) were overexpressed in the follicular phase. Conversely, during the luteal phase there were factors overexpressed (including moesins, syndecans, integrins, among others) that could play direct or indirect roles in enhancing HIV-1 infection. Thus, our study showed that specific pathways and proteins/genes might be working in tandem to regulate innate immunity, thus fostering further investigation and future design of approaches to help counter HIV-1 acquisition in the female genital tract. Samples were hybridized to Affymetrix GeneChip® Rhesus Macaque Genome Arrays. Vaginal pinch biopsies were collected from 12 pig-tailed macaques at both the follicular and luteal phases. The data from one animal suggested low RNA quality and was excluded.

Project description:Use of hormonal contraceptives (HC) could alter the bacterial community, immune response and epithelial barrier integrity of the female genital tract (FGT) mucosal environment, leading to increased susceptibility to sexually transmitted infections (STIs), including HIV. Here, we tested whether use of three types of HCs, injectable Net-En, combined oral contraceptives (COC) and NuvaRing, a combined contraceptive vaginal ring (CCVR), led to distinct patterns in FGT host transcriptomics transcriptome in South African adolescent females. In an intention-to-treat analysis, we observed few changes in endocervical gene expression in the Net-En and COC groups. Relative to the COC and Net-En arms, samples from the CCVR arm had significant elevation of transcriptional networks driven by IL-6, IL-1 and NFKB, and lower expression of genes supporting epithelial barrier integrity. An integrated multivariate analysis of the cervicovaginal microbiome, transcriptome and cytokines demonstrated that networks of microbial dysbiosis and inflammation accurately discriminated the CCVR arm from the other contraceptive groups, while genes involved in epithelial cell differentiation were predictive of the Net-En and COC arms.

Project description:Some evidence suggests that contraceptive use may influence the female genital tract (FGT) mucosal environment. However, comparative analysis of the effects of the most commonly used hormonal and non-hormonal contraceptives on the FGT host gene expression profile have not been evaluated in detail in a randomized clinical trial setting. Among 188 women enrolled in the Evidence for Contraceptive Options and HIV Outcomes (ECHO) trial (Clinicaltrials.gov ID NCT02550067) between December 2015 and September 2017, we evaluated the effect of three contraceptive methods, injectable intramuscular depot medroxyprogesterone acetate (DMPA-IM), levonorgestrel (LNG) implant, and a non-hormonal T-380 copper intrauterine contraceptive device (Cu-IUD), on the endocervical host transcriptome at baseline and after one month of randomized contraceptive use, using RNA-Seq transcriptomic analysis.
