Project description:Deer antler-derived reserve mesenchyme cells (RMCs) are a promising source of cells for cartilage regeneration therapy due to their chondrogenic differentiation potential. However, the regulatory mechanism has not yet been elucidated. microRNAs (miRNAs) have been shown to regulate the differentiation of various mesenchymal stem cells (MSCs) and play an important role in the post-transcriptional regulation of chondrogenesis and hypertrophic differentiation. In this study, we demonstrated that the RMCs showed typical MSCs differentiation potentials. During chondrogenic differentiation, we obtained the expression profile of miRNAs, among which miR-145 was the most prominent candidate as key microRNA involved in the balance of chondral and endochondral differentiation. Knockdown of miR-145 promoted chondrogenesis and inhibits hypertrophy differentiation in RMCs. Mechanically, by online databases prediction combined with dual-luciferase reporter assay, SOX9 was suggested as a target of miR-145. Further validation experiments confirmed that knockdown of miR-145 contributed to the balance between endochondral versus chondral differentiation of RMCs by targeting SOX9. Additionally, RMCs transfected with the miR-145 knockdown mediated of lentiviral vector successfully promoted cartilage regeneration in vivo. In summary, our study suggested that the reciprocal negative feedback between SOX9 and miR-145 was essential for balancing between endochondral versus chondral differentiation of RMCs. Our study suggested that modification of RMCs using miRNAs transduction might be an effective treatment for cartilage defects.

Project description:As the only regenerative organ of mammals, antler could grow rapidly without carcinogenesis. To understand the molecular mechanisms of the growth of sika deer antler, we used de novo RNA-seq analyses to determine the differential expression of unigenes and miRNAs from antler at 15, 60, 90, and 110-day. A total of 55004 unigenes, 208 known miRNAs and 38 novel miRNAs were identified. 10182 unigenes and 35 miRNAs were differentially expressed between 60-day and 15-day antler, 13258 unigenes and 53 miRNAs were differentially expressed between 90-day and 60-day antler, and 10740 unigenes and 27 miRNAs were differentially expressed between 110-day and 90-day antler. GO and KEGG analyses showed that DE unigenes and miRNA were mainly related to chondrogenesis, osteogenesis and inhibition of oncogenesis, that were closely associate with antler growth. We also constructed mRNA-mRNA and miRNA-mRNA interaction networks related to chondrogenesis, osteogenesis and inhibition of oncogenesis of antler. The results showed that mRNA (COL2A1, SOX9, WWP2, FGFR1, SPARC, LOX etc.) and miRNAs (miR-145, miR-199a-3p, miR-140, miR-199a-5p etc.) may play important roles in chondrogenesis and osteogenesis of antler, and mRNA (TP53, Tpm3 and ATP1A1 etc.) and miRNAs (miR-106a, miR-145, miR-1260b and miR-2898 etc.) may have key roles in inhibiting the carcinogenesis of antlers. In this study, we identified miRNAs and unigenes related to chondrogenesis, osteogenesis and inhibition of oncogenesis of antler. This will provide a reference for in-depth analysis of the molecular mechanism of antler growth without carcinogenesis, and also provide valuable information for cartilage- and bone-related disease treatment, cancer treatment.

Project description:Deer antlers are amazing natural appendages that grow faster than any other known mammalian bone. Antler growth occurs at the tip and is initially cartilage, which is later replaced by bone tissue. However, little is known regarding the precise role of cooperation between cell lineages and functional genes in regulating antler growth, and molecular mechanisms responsible for rapid growth remain elusive. In this study, we use an RNA-Seq approach to identify miRNA expression patterns during antler growth.

Project description:The velvet antler is a unique model for cancer and regeneration research due to its periodic re-generation and rapid growth. Antler growth is mainly triggered by the growth center located in its tip, which consists of velvet skin, mesenchyme and cartilage. Among them, cartilage accounts for most of the growth center. We performed an integrative analysis of the antler cartilage tran-scriptome and proteome at different antler growth stages. RNA-seq results revealed 24,778 uni-genes, 19,243 known protein-coding genes, and 5,535 new predicted genes. Of these, 2,722 were detected with differential expression patterns among 30 d, 60 d, and 90 d libraries, and 488 dif-ferentially expressed genes (DEGs) were screened at 30 d vs. 60 d and 60 d vs. 90 d but not at 30 d vs. 90 d. Proteomic data identified 1,361 known proteins and 179 predicted novel proteins. Compar-ative analyses showed 382 differentially expressed proteins (DEPs), of which 16 had differential expression levels at 30 d vs. 60 d and 60 d vs. 90 d but not at 30 d vs. 90 d. An integrated analysis conducted for DEGs and DEPs showed that gene13546 and its coding protein protein13546 anno-tated in the Wnt signaling pathway may possess important bio-logical functions in rapid antler growth. This study provides in-depth characterization of candidate genes and proteins, providing further insights into the molecular mechanisms controlling antler development.

Project description:Purpose: The goal of this study is to compare (RNA-seq) transcriptomes of in vitro cultured human bone marrow-derived mesenchymal stem cells (hMSCs) and fallow deer antler-derived skeletal progenitors (FD RM Cells) under multiple conditions to identify candidate proliferation and mineralization genes responsible for fast antler regeneration Methods: hMSCs and FD RM Cells were cultured in vitro under 1) serum-free (0% serum) or serum (10% serum) conditions for 2.5 days or 2) Control (0 ng/mL BMP-2 and 0 nM dexamethasone) and osteogenic (100 ng/mL BMP-2 and 100 nM dexamethasone) media for 24 days. mRNA profiles were generated by deep sequencing, in duplicate, using Illumina HiSeq 2000. The sequence reads were analyzed at the transcript isoform level STARS followed by Cufflinks. Validation for genes of interest was performed using immunofluorescence staining. Results: Comparison of human and fallow deer skeletal progenitor datasets yielded proliferation and mineralization gene candidates Conclusions: Our study represents the first detailed analysis of human and fallow deer transcriptomes of skeletal progenitor cells under proliferation and mineralization conditions, with biologic replicates, generated by RNA-seq technology. Our in vitro comparative approach circumvent some of the logistical and technical challenges in identifying candidate proliferation and mineralization genes responsible for rapid deer antler regeneration. We conclude that in vitro comparison of RNA-seq based transcriptomes identified candidate proliferaiton and mineralization genes to advance bone biology and holds promise to rapidly regenerate large bone volumes for regenerative medicine. The comparative approach utilized here can be adapted for almost any tissue to study a specific phenomenon of interest.
