Project description:Objective: Detection and analysis of Mongolian medicine Narenmandula the kernel full of adriamycin nephrosis rats kidney tissue expression of miRNA. Methods: The biological information of the differentially expressed miRNA between the normal group, the model group and the Mongolian medicine Narenmandula group was studied by Affymetrix miRNA chip detection. Results: The biological information of miRNA expression in kidney tissues of rats with doxorubicin nephropathy was analyzed by detection, which laid a foundation for further elucidating the multi-target regulatory role of Mongolian medicine Narenmandula in renal function protection and provided data. The biological information of miRNA expression in renal tissues of doxorubicin rats was detected and analyzed using Affymetrix miRNA chip detection technology, which laid a foundation for further elucidating the multi-target regulation effect of the renal function protection and provided data of Mongolian medicine Narenmandula .

Project description:Mongolian gerbil (Meriones unguiculatus) is an ideal animal model for non-alcoholic fatty liver disease/nonalcoholic steatohepatitis (NAFLD/NASH) which is under development. Currently, the research and application of Mongolian gerbils have been largely limited due to the lack of genomic and transcriptome information. In the present study, we sought to better understand the underlying mechanism of the rapid development of NASH in high-fat diet (HFD)-fed Mongolian gerbils by analyzing the transcriptome profilings of different modeling times. Eight hub genes CD44, APP, CDC42, CD68, CXCR4, CSF1R, ADGRE1 and FERMT3 were obtained, which are all involved in inflammation response and CDC42 and FERMT3 are associated with hepatocellular carcinoma (HCC). Most of the hub genes showed high expression levels in the first stage of modeling-building (HFD for 4 weeks). We observed that feeding HFD for 4 weeks is sufficient to induce high expression of pro-fibrotic factors such as PDGFB and CTGF and to form collagen deposits. Intriguingly, we found four significant independent prognostic factors for HCC: GPC1, ARPC1B, DAB2 and CFL exhibiting high expression levels during the modeling time. Our findings indicated that, Mongolian gerbil is an ideal NAFLD model with rapid progression in inflammation and fibrosis. Prolonging the modeling time may lead to the formation of NAFLD-related HCC and further research is needed to investigate this possibility.
Project description:We recruited 24 Mongolian volunteers,6 of which were T2D cases(sample T1-T6), 6 were prediabetes cases(sample P1-P6), and 12 were health cases(sample C1-C12). The metagenomic analysis of gut microbiota from the volunteers’ fecal samples was performed. We compared the microbial differences in the three groups, and analyzed the differences of the stool microbial function.
Project description:The mechanism of body growth in mammals is poorly understood. Here, we report the regulatory networks involved in body growth through analyzing transcriptomes of pituitary and epiphyseal tissues of Debao ponies and Mongolian horses at juvenile and adult stages. We found that GHR was expressed little in long bones though GH was highly expressed in Debao ponies compared with Mongolian horses. Moreover, m-RAS and ATF3, involved in the GHR pathway, were found to be significantly downregulated in juvenile ponies, which slowed the proliferation of bone osteocytes. However, WNT2 and PLCβ2 were obviously upregulated in juvenile Debao ponies, which led to premature mineralization of bone extracellular matrix. Furthermore, we found that the WNT/Ca2+ pathway may be responsible for the regulation of body growth. We then demonstrated that GHR was lacking in long bones of Debao ponies using RT-qPCR and Western blot. Treatment with WNT antagonist 1 decreased expression of the WNT pathway (P≤0.05) in vitro. The transduction of ATDC5 cells with GHR-RNAi lentivirus decreased expression of the GHR pathway (P≤0.05). Additionally, detection of plasma hormone concentrations showed that the ponies had higher levels of IGF-1 as juveniles and GH in adulthood than Mongolian horses, indicating that the hormone regulation in Debao ponies differs from that in Mongolian horses. Our work provides an insight into the genetic regulation for dwarf growth in mammals and a reference for therapeutic strategy for dwarfism
