Project description:Insight into Genes Regulating Hair Follicle Morphogenesis and Pigmentogenesis of Bay Mongolian Horse from Transcriptional Profiling

Project description:Inner Mongolia Cashmere Goat is a local excellent breed of cashmere and meat dual-purpose, which is a typical heterogeneous indumentum. The hair follicles cycle through periods of vigorous growth (anagen), a regression caused by apoptosis (catagen), and relative rest (telogen). At present, it is not clear which genes affect the cycle transformation of hair follicles and unclear how proteins impact the creation and expansion of hair follicles. In this work, we investigated the possible pathways of transformation and apoptosis in goat hair follicles using multi-omics joint analysis methodologies. The results showed that 917 , 1187 and 716 proteins were specifically expressed in anagen, catagen and telogen. The result of gene ontology (GO) annotation showed that differentially expressed proteins（DEPs) are in different growth cycle periods, and enriched GO items are mostly related to the transformation of cells and proteins. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment result indicated that the apoptosis process has a great impact on hair follicle's growth cycle. The results of the protein interaction network of differential proteins showed that the Ribosomal Protein family ( RPL4, RPL8, RPS16, RPS18, RPS2, RPS27A, RPS3 ) was the core protein in the network. The results of combined transcriptome and proteomics analysis showed that there were 16,34, and 26 overlapped DEGs and DEPs in the comparison of anagen VS catagen, catagen VS telogen and anagen VS telogen, of which API5 plays an important role in regulating protein and gene expression levels. We focused on API5 and Ribosomal protein and found that API5 affected the apoptosis process of hair follicles, and Ribosomal Protein was highly expressed in the resting stage of hair follicles. They are both useful as molecular marker candidate genes to study hair follicle growth and apoptosis, and they both have an essential function in the cycle transition process of hair follicles. The results of this study may provide a theoretical basis for further research on the growth and development of hair follicles in Inner Mongolian Cashmere goats.

Project description:The Mongolian horse has the characteristics of cold resistance, rough feeding resistance, good endurance, strong disease resistance and strong gregariousness. The normal production of sperm in male mammals is the basis of reproduction, and spermatogenesis includes a mitosis, meiosis twice and metamorphosis of sperm cells. The MEI1 gene is involved in the meiosis cycle and is required for normal meiosis chromosome association. Previous studies have shown that alternative splicing of MEI1 gene can promote spermatogenesis in Mongolian horses. In this study, the expression of MEI1 gene was determined by immunofluorescence in the third generation Mongolian horse testicular sertoli cells. Two overexpressed lentiviral vectors with MXE and SE events of MEI1 gene were constructed and successfully infected into sertoli cells. CCK-8 was used to detect the proliferation and activity of infected cells, transcripomics and metabolomics were used to screen and annotate differential genes and differential metabolites in the two sertoli cells with MXE and SE events. After 72 h of virus infection, 193 differentially expressed genes and 11360 differentially expressed metabolites were screened, 109 up-regulated genes including MEI1 and 84 down-regulated genes, 7494 up-regulated metabolites and 3866 down-regulated metabolites. Differential genes and differential metabolites were mainly enriched in several pathways related to spermatogenesis. Differential genes such as IL31RA, ATP2B3, CASQ2 were highly expressed in SE events, IL11, PRLR, CCR7 were highly expressed in MXE events. Metabolites such as folic acid and spermine were highly expressed in SE events, citric acid and glutathione were highly expressed in MXE events. This suggested that both MXE and SE events of MEI1 gene can promote the activity of spermatogenesis signaling pathway, and the gene influences spermatogenesis by regulating the expression of metabolites. In summary, MXE and SE events of MEI1 gene can promote the expression of spermatogen-related genes and metabolites, and genes affect spermatogenesis by regulating the expression of metabolites. The results of this study laid a theoretical foundation for exploring the regulatory mechanism of different alternative splicing events on spermatogenesis in Mongolian horse.

Project description:Mouse hair follicles undergo synchronized cycles. Cyclical regeneration and hair growth is fueled by stem cells (SCs). Following hair regeneration, SCs within the bulge and its vicinity (upper ORS which becomes the bulge for the next cycle) briefly self-renew to replenish expended SCs and ensure long-term tissue regeneration. We used microarrays to detect the relative levels of global gene expression influenced by transcription factor Tbx1 in order to gain insight into how Tbx1 is invovled in regulating hair follicle SC self-renewal and long-term regeneration. Fourty eight hours after deplicaiton induced hair regeneration, hair follicle SCs were FACS-purified for RNA extraction and hybridization on Affymetrix microarrays. To obtain homogeneous populations of expression profiles, we applied FASC technique to purify SC according to their cell surface markers.

Project description:CD133 is expressed by a subpopulation of human fetal hair follicle placode cells during early hair development. Its expression, which is gradually lost as the placode matures, correlates with early morphogenesis. We used microarrays to analyze differences in gene expression between alpha-6 integrin+CD133+ basal cells and other human fetal epidermal populations to provide candidates defining this unique hair follicle placode subpopulation.

Project description:Cashmere, also known as soft gold, is produced from secondary hair follicles in Cashmere goats and it’s therefore of significance to investigate the molecular profiles during Cashmere goat hair follicle development. However, our current understanding of the machinery underlying Cashmere goat hair follicle remains largely unexplored and researches regarding hair follicle development mainly used the mouse as a research model. To provides comprehensively understanding on the cellular heterogeneity and cell lineage cell fate decisions, we performed single-cell RNA sequencing on 19,705 single cells from induction (embryonic day 60), organogenesis (embryonic day 90) and cytodifferentiation (embryonic day 120) stage fetus Cashmere goat dorsal skin. Unsupervised clustering analysis identified 16 cell clusters and their corresponding cell types were also successfully characterized. Based on cell lineage inference, we revealed detailed transcriptional gene expression profiles during dermal and epidermal lineage cell fate decisions. These works together delineate unparalleled molecular profiles of different cell populations during Cashmere goat hair follicle morphogenesis and provide a valuable resource for identifying biomarkers during Cashmere goat hair follicle development.

Project description:We performed single-cell RNA seq on C57/BL6 mouse back skin at E13.5, E16.5, and P0 to study embryonic hair follicle development. We analyzed 15,086 single cell transcriptome profiles from E13.5, E16.5 and newborn mice (postnatal day 0, P0) dorsal skin cells across hair follicle induction, organogenesis, cytodifferentiation stage. Based on t-distributed Stochastic Neighbor Embedding (tSNE) clustering, we identified 14 cell clusters from skin cells and delineated their cell identity gene expression profile. By using Monocle pseudotime ordering analysis, we constructed epithelium/dermal cell lineage differentiation trajectory and revealed sequential activation of key regulons involved during embryonic hair follicle morphogenesis. Our findings here provide molecular landscape during hair follicle epithelium/dermal cell lineage fate decisions.
