Project description:Rib bone growth in red deer stags - Abstract: In 'The Bone and Joint Decade' interest is focused on genetic factors causing bone disorders. Osteoporosis, attacking 10% of the population worldwide, is the most common metabolic bone disease, which is mimiced by several ovarectomised or genetically modified 'cascadeur' animal species, but none of them is able to remedy its pathologically porous bone tissue. Regeneration in skeletal elements is the curiosity of our newly investigated osteoporosis animal model, red deer (Cervus elaphus). The cyclic physiological osteoporosis in red deer stag is a consequence of the annual antler cycle. This phenomenon raises the possibility to explore new genes involved in regulating bone mineral density (BMD) and recovery of bone resorption on the basis of comparative genomics between deer and human. Here we compared the gene expression activities of osteoporotic and regenerating flying rib bone samples versus late autumn dwell control in red deer by heterologous microarray hybridization. Identified genes were tested on human femoral bone tissue from postmenopausal osteoporotic and non-osteoporotic patients. Expression data were evaluated by Principal Components Analysis and Discriminant Analysis. Keywords: Gene Expression experiment Approximately 2-3 g flying rib bone pieces in the entire cross section of bony rib were surgically removed from 3 anaesthetized [SBH-Ketamine (2.5 mg/kg live weight) combined with Xylazine (0.2 mg/kg live weight) i.m. injection] 6, 7 and 8 year old Cervus elaphus stags. (Cast antler pairs weighed 7-8 kg for each animal.) Removed rib pieces were extensively washed in PBS for eliminating blood and marrow contamination, than immediately frozen in liquid nitrogen. The time of tissue collections were (i) within the period of the active mineralization of antler, at the beginning of June when skeletal osteoporosis takes place, (ii) in the fitness improvement period with velvet shedding in late July, that is the 'regenerating time' and (iii) in the period of late autumn dwell at the end of November when in the skeleton the mineral mobilization and deposition are dynamically equilibrated (BMD is in steady state). Each comparison performed on Platforms GPL4052 and GPL5352.

Project description:we used proteomic technology to disclose the difference of antler regeneration between red deer and sika deer. Through functional analysis, we obtained differentially expressed proteins and the pathway involved in antler regeneration between two groups

Project description:We have previously described the reindeer antler velvet as a highly unique mammalian model of adult skin regeneration as wounds on backskin form a raised, contractile scar devoid of appendages or pigment, whereas identical wounds in antler velvet exhibit scar-less regeneration. To ask whether regenerative capacity is inherent to cells within the velvet (and not due to factors derived from the antler environment), we transplanted full thickness velvet skin grafts onto dorsal backskin. This scRNA-Seq sample profiles cells within the ectopic velvet graft to assess their molecular resemblance to regenerative velvet or non-regenerative dorsal backskin.

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:To elucidate the complex physiological process of the growth, development and immunity response of Sika Deer, this study evaluated the changes of miRNA profiles in the four developmental stages (juvenile, adolescence, adult and aged) of ten tissue (adrenal, antler, brain, heart, kidney, lung, liver, skeletal muscle, spleen and testes). The results showed that a total of 306 known miRNAs and 143 novel miRNAs were obtained. Many miRNAs displayed organ-specificity and age-specificity. The largest number of miRNAs were enriched in the brain, some of which were shared only between the brain and adrenal. These miRNAs were involved in maintaining specific functions within the brain and adrenal. Additionally, the adolescence-adult transition of Sika Deer was a crucial stage in its life cycle. In conclusion, our study provided abundant data support for the current research Sika Deer. It also contributes to understand the role of miRNAs play in regulating the growth, development and immunity response of Sika Deer.

Project description:We present the analysis of an osseous finger ring from an early Neolithic context in Denmark. To characterise the artefact and identify the raw material used for its manufacture, we performed micro-computed tomography (Micro CT) scanning, zooarchaeology by mass spectrometry (ZooMS) peptide mass fingerprinting, as well as protein sequencing by liquid chromatography tandem mass spectrometry (LC-MS/MS). We found that the ring was made from long bone or antler due to the presence of osteons (Haversian canals). Subsequent ZooMS analysis of the collagen present indicated that it was made from either elk (Alces alces) or red deer (Cervus elaphus) material. We then used LC-MS/MS analysis to refine our species identification, confirming that the ring was made from red deer, and to examine other proteins present. This study demonstrates the potential of ancient proteomics for species identification of prehistoric artefacts made from osseous material.

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.
