Project description:Studies of the gene expression profiles associated with the postnatal late growth, development and aging of skeletal muscle are lacking in sika deer. To understand the molecular mechanisms of the growth and development of sika deer skeletal muscle, we used de novo RNA-seq analyses to determine the differential expression of unigenes from skeletal muscle tissues at 1, 3, 5, and 10-year-old in sika deer. A total of 51716 unigenes were identified based on four mRNA libraries. 2044 unigenes were differentially expressed between adolescence and juvenile sika deer, 1946 unigenes were differentially expressed between adult and adolescence sika deer, and 2209 unigenes were differentially expressed between aged and adult sika deer. GO and KEGG analyses showed that DE unigenes were mainly related to energy and substance metabolism, processes that are closely associate with growth, development and aging of skeletal muscle. We also constructed mRNA-mRNA interaction networks related to growth, development and aging of skeletal muscle. The results showed that Myh1, Myh2, Myh7, ACTN3 etc. may play important roles in muscle growth and development, and WWP1, DEK, UCP3, FUS etc. may have key roles in muscle aging. In this study, we determined the dynamic unigenes transcriptome in muscle tissue for the first time in sika deer. The age-dependent unigenes identified will offer insights into the molecular mechanism underlying muscle development, growth and maintenance and also provide valuable information for sika deer genetic breeding.

Project description:In eutherian mammals, dosage compensation of X-linked genes is achieved by X chromosome inactivation. X inactivation is random in embryonic and adult tissues, but imprinted X inactivation (paternal X silencing) has been identified in the extraembryonic membranes of the mouse, rat, and cow. Few other species have been studied for this trait, and the data from studies of the human placenta have been discordant or inconclusive. Here, we quantify X inactivation using RNA sequencing of placental tissue from reciprocal hybrids of horse and donkey (mule and hinny). In placental tissue from the equid hybrids and the horse parent the allelic expression pattern was consistent with random X inactivation, and imprinted X inactivation can clearly be excluded. We characterized horse and donkey XIST gene, and demonstrated that XIST allelic expression in female hybrid placental and fetal tissues is negatively correlated with the other X-linked genes chromosome-wide, which is consistent with the XIST-mediated mechanism of X inactivation discovered previously in mice. As the most structurally and morphologically diverse organ in mammals, the placenta also appears to show diverse mechanisms for dosage compensation that may result in differences in conceptus development across species. Examine allelic expression from individual samples of invasive trophoblast tissue of the chorionic girdle from gestation day 33-34 conceptuses of 5 horses, 3 donkeys, 6 mules, and 1 hinny.

Project description:Studies of the miRNA expression profiles associated with the postnatal late growth, development and aging of skeletal muscle are lacking in sika deer. To understand the molecular mechanisms of the growth and development of sika deer skeletal muscle, we used de novo RNA-seq analyses to determine the differential expression of miRNAs from skeletal muscle tissues at 1, 3, 5, and 10-year-old in sika deer. A total of 171 known miRNAs and 60 novel miRNAs were identified based on four small RNA libraries. 11 miRNAs were differentially expressed between adolescence and juvenile sika deer, 4 miRNAs were differentially expressed between adult and adolescence sika deer, and 1 miRNAs were differentially expressed between aged and adult sika deer. GO and KEGG analyses showed that miRNA were mainly related to energy and substance metabolism, processes that are closely associate with growth, development and aging of skeletal muscle. We also constructed mRNA-mRNA and miRNA-mRNA interaction networks related to growth, development and aging of skeletal muscle. The results showed that miR-133a, miR-133c, miR-192, miR-151-3p etc. may play important roles in muscle growth and development, and miR-17-5p, miR-378b, miR-199a-5p, miR-7 etc. may have key roles in muscle aging. In this study, we determined the dynamic miRNA in muscle tissue for the first time in sika deer. The age-dependent miRNAs identified will offer insights into the molecular mechanism underlying muscle development, growth and maintenance and also provide valuable information for sika deer genetic breeding.

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:BACKGROUND: Tetherin is an interferon-inducible host cell factor that blocks the viral particle release of the enveloped viruses. Most knowledge regarding the interaction between tetherin and viruses has been obtained using the primate lentiviral system. However, much less is known about the functional roles of tetherin on other lentiviruses. Equine infectious anemia virus (EIAV) is an important macrophage-tropic lentivirus that has been widely used as a practical model for investigating the evolution of the host-virus relationship. The host range of EIAV is reported to include all members of the Equidae family. However, EIAV has different clinical responses in horse and donkey. It's intriguing to investigate the similarities and differences between the tetherin orthologues encoded by horse and donkey. RESULTS: We report here that there are two equine tetherin orthologues. Compared to horse tetherin, there are three valine amino acid deletions within the transmembrane domain and three distinct mutations within the ectodomain of donkey tetherin. However, the antiviral activity of donkey tetherin was not affected by amino acid deletion or substitution. In addition, both tetherin orthologues encoded by horse and donkey are similarly sensitive to EIAV Env protein, and equally activate NF-?B signaling. CONCLUSION: Our data suggest that both tetherin orthologues encoded by horse and donkey showed similar antiviral activities and abilities to induce NF-?B signaling. In addition, the phenomenon about the differential responses of horses and donkeys to infection with EIAV was not related with the differences in the structure of the corresponding tetherin orthologues.

Project description:Divergence of gene expression and alternative splicing is a crucial driving force in the evolution of species; to date, however the molecular mechanism remains unclear. Hybrids of closely related species provide a suitable model to analyze allele-specific expression (ASE) and allele-specific alternative splicing (ASS). Analysis of ASE and ASS can uncover the differences in cis-regulatory elements between closely related species, while eliminating interference of trans-regulatory elements. Here, we provide a detailed characterization of ASE and ASS from 19 and 10 transcriptome datasets across five tissues from reciprocal-cross hybrids of horse×donkey (mule/hinny) and cattle×yak (dzo), respectively. Results showed that 4.8%-8.7% and 10.8%-16.7% of genes exhibited ASE and ASS, respectively. Notably, lncRNAs and pseudogenes were more likely to show ASE than protein-coding genes. In addition, genes showing ASE and ASS in mule/hinny were found to be involved in the regulation of muscle strength, whereas those of dzo were involved in high-altitude adaptation. In conclusion, our study demonstrated that exploration of genes showing ASE and ASS in hybrids of closely related species is feasible for species evolution research.
