Project description:Single-nucleus RNA sequencing (snRNA-seq) was used to profile the transcriptome of 16,015 nuclei in human adult testis. This dataset includes five samples from two different individuals. This dataset is part of a larger evolutionary study of adult testis at the single-nucleus level (97,521 single-nuclei in total) across mammals including 10 representatives of the three main mammalian lineages: human, chimpanzee, bonobo, gorilla, gibbon, rhesus macaque, marmoset, mouse (placental mammals); grey short-tailed opossum (marsupials); and platypus (egg-laying monotremes). Corresponding data were generated for a bird (red junglefowl, the progenitor of domestic chicken), to be used as an evolutionary outgroup.

Project description:Gene expression in FIH-1 silenced human nucleus pulposus cells
| PRJNA241120 | ENA
Project description:Background: The nucleus pulposus is a constituent structure of the human intervertebral disc, and its degeneration can cause Intervertebral disc degeneration (IDD). However the cellular molecular mechanisms involved remain elusive. Methods: Through bioinformatics analysis, the single-cell transcriptome sequencing expression profiles of human normal nucleus pulposus cells (NNP) and human degenerative nucleus pulposus cells (DNP) were compared to clarify the transcriptome differential expression profiles of human normal and human degenerative nucleus pulposus cells. The single-cell sequencing results of the two samples were analyzed using bioinformatics methods to compare the differences in histiocytosis between human normal nucleus pulposus and human degenerated nucleus pulposus, map the histiocytes of NNP and DNP, perform cell differentiation trajectories for the cell populations of interest and predict cell function, and explore their heterogeneity by pathway analysis and Gene ontology analysis. Results: Nine cell types were identified, which were Chondrocyte1, Chondrocyte2, Chondrocyte3, Chondrocyte4, Chondrocyte5, Endothelial, Macrophage, Neutrophil, and T cells. Analysis of the proportion of chondrocytes in different tissues revealed that chondrocyte 1 accounted for a higher proportion of normal nucleus pulposus cells and highly expressed COL2A1 compared with degenerated nucleus pulposus cells; chondrocyte 2, chondrocyte 3, chondrocyte 4, and chondrocyte 5 accounted for a higher proportion of degenerated nucleus pulposus cells compared with normal nucleus pulposus cells. Among them, chondrocyte 2 was an inhibitory calcified chondrocyte with high expression of MGP, Chondrocytes 3 were fibrochondrocytes with high expression of COL1A1, Chondrocytes 4 are chondrocytes that highly express pain inflammatory genes such as PTGES, Chondrocytes 5 were calcified chondrocytes with high expression of FN1. (Chondrocytes 4 and chondrocytes 5 were found for the first time in a study of single-cell transcriptome sequencing of disc tissue.) Cell trajectory analysis revealed that chondrocyte 1 was at the beginning of the trajectory and chondrocyte 3 was at the end of the trajectory, while chondrocyte 5 appeared first in the trajectory relative to chondrocyte 2 and chondrocyte 4. Conclusion: After functional identification of the specifically expressed genes in five chondrocytes, it was found that chondrocyte 1 was a chondrocyte with high expression of COL2A1, COL9A2, COL11A2, and CHRDL2 in a high proportion of normal nucleus pulposus cells, and chondrocyte 3 was a fibrochondrocyte with high expression of COL1A1, COL6A3, COL1A2, COL3A1, AQP1, and COL15A1 in an increased proportion during nucleus pulposus cell degeneration. Through cell trajectory analysis, it was found that chondrocytes 5 specifically expressing FN1, SESN2, and GDF15 may be the key cells leading to degeneration of nucleus pulposus cells. Chondrocytes 2 expressing MGP, MT1G, and GPX3 may play a role in reversing calcification and degeneration, and chondrocytes 4 expressing PTGES, TREM1, and TIMP1 may play a role in disc degeneration pain and inflammation.

Project description:Synovial and bone marrow mesenchymal stem cells after intradiscally injection show regenerative effects of nucleus pulposus. Microarray analyses of rats were performed to investigate the closeness of the gene profiles between the nucleus pulposus cells and the synovial or bone marrow mesenchymal stem cells. To investigate interaction between synovial mesenchymal stem cells and nucleus pulposus cells, human synovial mesenchymal stem cells and rat nucleus pulposus cells were co-cultured, and species specific microarray were performed. Synovium of knee joints, bone marrow and nucleus pulposus were harvested from rat or human, and cells were isolated for RNA extraction and hybridization on Affymetrix microarrays. To compare the gene profiles each other, isolated cells were mono-cultured respectively, and human synovial mesenchymal stem cells and rat nucleus pulposus cells were co-cultured.

Project description:We have sequenced miRNA libraries from human embryonic, neural and foetal mesenchymal stem cells. We report that the majority of miRNA genes encode mature isomers that vary in size by one or more bases at the 3’ and/or 5’ end of the miRNA. Northern blotting for individual miRNAs showed that the proportions of isomiRs expressed by a single miRNA gene often differ between cell and tissue types. IsomiRs were readily co-immunoprecipitated with Argonaute proteins in vivo and were active in luciferase assays, indicating that they are functional. Bioinformatics analysis predicts substantial differences in targeting between miRNAs with minor 5’ differences and in support of this we report that a 5’ isomiR-9-1 gained the ability to inhibit the expression of DNMT3B and NCAM2 but lost the ability to inhibit CDH1 in vitro. This result was confirmed by the use of isomiR-specific sponges. Our analysis of the miRGator database indicates that a small percentage of human miRNA genes express isomiRs as the dominant transcript in certain cell types and analysis of miRBase shows that 5’ isomiRs have replaced canonical miRNAs many times during evolution. This strongly indicates that isomiRs are of functional importance and have contributed to the evolution of miRNA genes
