Bovine natural immune system phenotyping via a standardized total blood activation assay.
The genetic diversity and phylogenetic relationships of sika deer of different subspecies are uncertain. In order to explore the phylogenetic relationship of different sika deer subspecies, this study used a wider sample collection to analyze mitochondrial sequences and nuclear microsatellites of sika deer. The full lengths of cytochrome-b gene of 134 sika deer were sequenced, and 16 haplotypes were obtained. Based on phylogenetic and haplotype networks analysis, the sika deer was not clustered according to subspecies but was divided into four lineages. Lineage I includes individuals from C.n.kopschi, C.n.sichuanicus, and C.n.hortulorum subspecies; Lineage II includes individuals from C.n.hortulorum subspecies; Lineage III includes individuals from C.n.centralis, C.n.yakushime, C.n.mageshimae, and C.n.keramae subspecies, namely southern Japanese population; Lineage IV includes individuals from C.n.centralis and C.n.yesoensis subspecies, namely northern Japanese population. The microsatellite analysis showed that the sika deer in China and Japan originated independently. The three subspecies of China have significant genetic differentiation, while the three subspecies of Japan have no significant differentiation. This study provides reference for the research of genetic diversity and phylogenetic relationship of sika deer, and also provides scientific data for the evaluation, protection, and utilization of sika deer resources.In Indian montane system, human populations often exhibit an unparallel social organization where inter-caste marriages are still not common. This attribute affects the demography and population genetic structure of the resident populations. Further, human populations residing in the mountains in India are poorly studied for their genetic make-up and allele distribution patterns. In the present study, we genotyped 594 unrelated individuals using PowerPlex® 21 System (Promega, USA) from eight different populations belonging to 12 districts of Himachal Pradesh which differed in ethnicity, language, geography and social organization. Altogether, we obtained 1415 alleles with a mean of 8.84 ± 0.26 alleles per locus and 0.80 mean observed heterozygosity. Locus Penta E showed the highest combined power of discrimination and was found most informative for forensic purposes. Interestingly, phylogenetic analysis grouped the populations of Rajputs, Scheduled castes and Brahmins into one cluster, which indicated a deep genetic admixture in the ancestral populations. This study documents the first-ever report on the population genetic assignment of various castes in Himachal Pradesh and unveils the facts of cryptic gene flow among the diverse castes in the northern hilly state of India. Our results showed a genetic relationship among the various ethno-linguistically diverse populations of India.Adiponectin is an important hormone that regulates systemic metabolism, and it has been reported that globular adiponectin promotes myogenic differentiation. However, the mechanisms by which adiponectin promotes myogenic differentiation is not fully understood. In the present study, we show that adiponectin and its receptor 1 are significantly up-regulated during myogenic differentiation and that adiponectin increased the expression level of a core myogenic regulator, Mef2C, which is required for the effects of adiponectin on promoting myogenic differentiation. A transcriptional inhibitor of Mef2C, HDAC9, was down-regulated by adiponectin. In turn, Mef2C overexpression up-regulates adiponectin and its receptor, AdipoR1, to increase myogenic differentiation. We showed that mechanistically, Mef2C directly binds to AdipoR1 promoter to transcriptionally up-regulate AdipoR1 expression, which is required for the effects of Mef2C overexpression on myogenic differentiation. Thus, adiponectin/AdipoR1 and Mef2c form a positive feedback loop to promote myogenic differentiation.Vitamin E is generally believed to promote the production of ovine sperm mainly through its antioxidant effect. Our previous studies have shown that some non-antioxidant genes may also be key in mediating this process. The objective of this study was to identify key candidate proteins that were differentially expressed in response to a treatment with Vitamin E. Prepubertal ovine testicular cells were isolated and divided into two groups. They were either treated with 800 μM Vitamin E (based on our previous results) or used as a non-treated control. After 24 h, all the cells were harvested for proteomic analysis. We found 115 differentially expressed proteins, 4 of which were up-regulated and 111 were down-regulated. A GO term enrichment analysis identified 127 Biological Process, 63 Cell Component and 26 Molecular Function terms that were enriched. Protoporphyrin IX cost Within those terms, 13, 11 and 26 terms were significantly enriched, respectively. Terms related to membrane and enzyme activity including the inner acrosomal membrane, signal peptidase complex, cysteine-type endopeptidase activity, etc., were also markedly enriched, while none of the KEGG pathways were enriched. We found that many of the differentially expressed proteins, such as CD46 (membrane cofactor protein), FLNA (Filamin A), DYSF (Dysferlin), IFT20 (Intraflagellar transport 20), SPCS1 (Signal peptidase complex subunit 1) and SPCS3 (Signal peptidase complex subunit 3) were related to the acrosomal and plasma membranes. A parallel reaction monitoring (PRM) analysis verified that Vitamin E improved spermatogenesis by regulating the expression of FLNA, SPCS3, YBX3 and RARS, proteins that are associated with the plasma membranes and protamine biosynthesis of the spermatozoa.Extracellular vesicles (EVs), have been utilised for the diagnosis and treatment of osteonecrosis of femoral head (ONFH). Hence, we aimed to review the available evidence on the potential roles of EVs in ONFH systematically. The PubMed, EMBASE, and Science Citation Index databases were searched exhaustively from inception to June 2020. All in vitro and in vivo studies on the use of EVs in ONFH diagnosis and treatment were included. The final analysis included 14 studies. These studies were categorised according to the cell source, target cell types, secreted product types, production method, storage, and study design. The animal model, together with the ONFH induction method, used in the in vivo studies was also considered. For in vivo studies, effects on cellular proliferation and apoptosis and bone and vascular tissues and biomarkers for ONFH diagnosis were assessed, whereas in the in vitro studies, effects on EVs internalization; proliferation, viability, and migration; osteogenic and adipogenic differentiation; apoptosis; and angiogenesis were evaluated.
