Single-cell analysis reveals transcriptional dynamics in primary parathyroid tissue

ABSTRACT: Studies on human parathyroid tissue are often limited to adenomatous tissue due to difficulty obtaining healthy tissue. We obtained nonhuman primate parathyroids to provide a suitable alternative for sequencing analysis that would bear the closest semblance to human organs as possible. We analyzed four M. mulatta normal parathyroid specimens to that show a continuous trajectory of cell states comprising the normal adult parathyroid. We calculated the predicted pseudotime progression based on transcriptomic signatures that were reflective of repopulating progenitors, progressing to chief cells, and ultimately oxyphils, and clustered genes based on their expression dynamics along this axis. As a comparator, we histologically characterized and sequenced four human adenomas with varying oxyphil and chief cell abundance to highlight similarities and differences to normal parathyroid cell expression dynamics. We noted abundant RARRES2 transcripts that were detected in both human adenoma and normal primate parathyroid cells, and provided co-immunostaining validation of Chemerin presence in PTH-expressing cells, which could play a previously unrecognized role in parathyroid endocrine function.

Human Parathyroid Gland: Normal vs. Adenoma

Project description:Transcriptional profiling of genes expressed in normal parathyroid glands (Normal) and adenomatous parathyroid glands from patients with primary hyperparathyroidism (PHPT). Stratagen Human Refernece RNA, pooled from 10 human cell lines, was used to identify genes, which are specifically expressed or suppressed in parathyroid tissue. Comparison between normal and tumor parathyroids shows genes that might be involved in hyperproliferation and PTH hypersecretion in tumors.

Chemerin triggers migration of a CD8 T cell subset with natural killer cell functions

Project description:We identified subsets of human CD28- effector CD8 T cells, of CCR7- CD45RO+ effector memory (EM) and CCR7- CD45RO- effector memory RA (EMRA) phenotypes, that express the chemerin receptor CMKLR1 and bind chemerin via the receptor. This study investigates differential gene expression between the chemerin binding and nonbinding human CD8 EMRA T cell subsets.

Primate Primordial Germ Cells Acquire Transplantation Potential by Carnegie Stage 23

Project description:Primordial germ cells (PGCs) are the earliest embryonic progenitors in the germline. Correct formation of PGCs is critical to reproductive health as an adult. Recent work has shown that primate PGCs can be differentiated from pluripotent stem cells; however, a bioassay that supports their identity as transplantable germ cells has not been reported. Here, we adopted a xenotransplantation assay by transplanting single-cell suspensions of human and nonhuman primate embryonic Macaca mulatta (rhesus macaque) testes containing PGCs into the seminiferous tubules of adult busulfan-treated nude mice. We discovered that both human and nonhuman primate embryonic testis are xenotransplantable, generating colonies while not generating tumors. Taken together, this work provides two critical references (molecular and functional) for defining transplantable primate PGCs. These results provide a blueprint for differentiating pluripotent stem cells to transplantable PGC-like cells in a species that is amenable to transplantation and fertility studies.

Comparison of proteome alternations during aging in temporal lobe from human and rhesus macaque

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.

Analysis of CNVs in the rhesus macaque genome identifies candidate loci for evolutionary and human disease studies

Project description:Copy number variants (CNVs) are heritable gains and losses of genomic DNA in normal individuals. While copy number variation is widely studied in humans, our knowledge of CNVs in other mammalian species is more limited. We have designed a custom array-based comparative genomic hybridization (aCGH) platform with 385,000 oligonucleotide probes based on the reference genome sequence of the rhesus macaque (Macaca mulatta), the most widely studied non-human primate in biomedical research. We used this platform to identify 123 CNVs among 10 unrelated macaque individuals, with 24% of the CNVs observed in multiple individuals. We found that segmental duplications were significantly enriched at macaque CNV loci. We also observed significant overlap between rhesus macaque and human CNVs, suggesting that certain genomic regions are prone to recurrent CNV formation and instability, even across a total of ~50 million years of primate evolution (~25 million years in each lineage). Furthermore, for 8 of the CNVs that were observed in both humans and macaques, previous human studies have reported a relationship between copy number and gene expression or disease susceptibility. Therefore, the rhesus macaque offers an intriguing, non-human primate model organism for which hypotheses concerning the specific functions of phenotypically-relevant human CNVs can be tested.
