Project description:To elucidate the complex physiological process of testis development and spermatogenesis in Sika deer, this study evaluated the changes of miRNA profiles in the four developmental stages of testis the juvenile (1-year-old), adolescence (3-year-old), adult (5-year-old) and aged (10-year-old) stages. The results showed that total total of 198 mature and 66 novel miRNAs were obtained. 88 (43 up and 45 down), 102 (44 up and 58 down), 54 (18 up and 36 down) DE miRNAs were identified in 3-vs.1-, 5-vs.3- and 10-vs.5-year-old testes, respectively. By integrating miRNA expression profiles, we predicted 69883 miRNA-mRNA interaction sites. The target genes were enriched by GO and KEGG pathways to obtain DE miRNA (miR-145, miR-140, miR-7, miR-26a, etc.), which play an important role in testis development and spermatogenesis. The data show that DE miRNAs could regulate testis developmental and spermatogenesis through signaling pathways, including MAPK signaling pathway, p53 signaling pathway, PI3K-Akt signaling pathway, Hippo signaling pathway, etc. It provides a useful resource for future studies on the role of miRNA regulation in testis development and spermatogenesis.

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:To elucidate the complex physiological process of testis development and spermatogenesis in Sika deer, this study evaluated the changes of miRNA and mRNA profiles in the four developmental stages of testis in the juvenile (1-year-old), adolescence (3-year-old), adult (5-year-old), and aged (10-year-old) stages. The results showed that a total of 198 mature, 66 novel miRNAs, and 23,558 differentially expressed (DE) unigenes were obtained; 14,918 (8,413 up and 6,505 down), 4,988 (2,453 up and 2,535 down), and 5,681 (2,929 up and 2,752 down) DE unigenes, as well as 88 (43 up and 45 down), 102 (44 up and 58 down), and 54 (18 up and 36 down) DE miRNAs were identified in 3- vs. 1-, 5- vs. 3-, and 10- vs. 5-year-old testes, respectively. By integrating miRNA and mRNA expression profiles, we predicted 10,790 mRNA-mRNA and 69,883 miRNA-mRNA interaction sites. The target genes were enriched by GO and KEGG pathways to obtain DE mRNA (IGF1R, ALKBH5, Piwil, HIF1A, BRDT, etc.) and DE miRNA (miR-140, miR-145, miR-7, miR-26a, etc.), which play an important role in testis development and spermatogenesis. The data show that DE miRNAs could regulate testis developmental and spermatogenesis through signaling pathways, including the MAPK signaling pathway, p53 signaling pathway, PI3K-Akt signaling pathway, Hippo signaling pathway, etc. miR-140 was confirmed to directly target mutant IGF1R-3'UTR by the Luciferase reporter assays. This study provides a useful resource for future studies on the role of miRNA regulation in testis development and spermatogenesis.

Project description:Antler is a special bone tissue that has the ability to regenerate completely periodically. It is the fastest growing bone in the animal kingdom. Antler provides a valuable research model for bone growth and mineralization. Antler grows longitudinally by endochondral ossification with their growth center located in its tip. Many scholars have carried out detailed studies on morphology and gene expression of antler tip. However, few scholars have analyzed the protein expression patterns of antler tip at different development stages. This study used label-free proteomics approach to analyze the protein expression dynamics of the antler tip in six developmental periods (15, 25, 45, 65, 100 and 130 days after the previous antler cast) and costal cartilage. In result, 2052 proteins were confidently quantified, including 1937 antler proteins and 1044 costal cartilage proteins. Moreover, 913 antler core proteins and 132 antler-special proteins were obtained. Besides, the stages special proteins and differentially expressed proteins (DEPs) in different development stages were analyzed. A total of 875 DEPs were determined by one-way AVOVA. It is found that the growth period (15, 25, 45 and 65 days) showed more up-regulated protein including several chondrogenesis-associated proteins (collagen types II, collagen types XI, HAPLN1, PAPSS1 and PAPSS2). In ossification stages, the up-regulated proteins related with lysosome (CTSD, CTSB, MMP9, CAII) indicated that the antler has higher bone remodeling activity. Given the up-regulated expression of immune-related molecules (S100A7, CATHL7, LTF, AZU1, ELANE and MPO), we speculate that the local immune system may contribute to the ossification of antler tip. In conclusion, proteomics technology was used to deeply analyze the protein expression patterns of antler at different development stages. This provides a strong support for the research on the molecular regulation mechanism of rapid growth and ossification of velvet antler.
