Project description:The yak estrus is a seasonal phenomenon, probably involving the epigenetic regulation of the synthesis and secretion of sex hormones as well as the growth and development of follicles. In this study, we collected the yak ovarian tissues at the three different states of anestrus, estrus, and pregnancy, and obtained the full transcriptome m6A map in yak by MeRIP-seq. The RT-qPCR showed that the expression of METTL3, METTL14, FTO, YTHDC1 were significantly different across different periods in the ovaries. Next, we identified 20174, 19747 and 13523 m6A peaks in the three ovarian samples of YO-A, YO-F and YO-P using the methylated RNA immunoprecipitation sequencing (MeRIP-seq). The m6A peaks are highly enriched in the coding sequence (CDS) region and 3′untranslated region (3′UTR) as well as the conserved sequence of “RRACH.” Functional analysis revealed the involvement of m6A in many physiological activities of the yak’s ovary during estrus and pregnancy. The association analysis found that some genes such as BNC1, HOMER1, BMP15, BMP6, GPX3, and WNT11 were related to ovarian functions. The comparison of the distribution patterns of methylation peaks in the ovarian tissues across different periods further explored the m6A markers related to the regulation of ovarian ovulation and follicular development in the yak ovary. This comprehensive map provides a solid foundation for revealing the potential function of the mRNA m6A modification in the yak ovary.
Project description:Deep sequencing of mRNA from 6 organs of yak (Bos grunniens) Analysis of ploy(A)+ RNA of brain,heart,liver,lung,spleen, and stomach of yak (Bos grunniens)
Project description:We report here mRNA-seq data of adult male Drosophila head tissues. We compare two different ages: young and midlife as well as chm/chameau (CG5229) heterozygous mutants.
Project description:This study provides a clear and accurate dynamic transcriptome profile of mRNAs in rumen, reticulum, omasum and abomasum of yaks. The results include high-quality genomic data and help to elucidate the important roles of these mRNAs in regulation of growth, development and metabolism in yaks, and to further understand the molecular mechanisms underlying metabolic regulation of yak stomach tissues. At the same time, it provided a theoretical basis for age-appropriate weaning and supplementary feeding in yaks.

Project description:16S rRNA Sequencing Reveals the Rumen Bacteria of the Yak (Bos Grunniens) in Different Ages
Project description:We studied microRNAs as potential biomarkers for Pompe disease (PD). We analyzed microRNA expression by small RNA-seq in tissues from the PD mouse model at two different ages (3 and 9 months), and in plasma from 6 PD patients. In the PD mouse we found 211 microRNAs that were differentially expressed in gastrocnemii and 66 in heart, with a different pattern of expression at different ages. In a preliminary analysis in plasma from 6 PD patients 55 microRNAs were differentially expressed.
Project description:Purpose：Yak long-term colonization and widespread distribution across the plateau can be serve as an ideal natural animal model to provide insights into the adaptive evolution of other plateau species, including humans. Methods:To exploring the molecular mechanisms of lung tissue in yak to response to hypoxia, the mRNA, lncRNA and miRNA of lung tissue from cattle and three different altitude yaks were sequenced. Results:A total of 21764 mRNAs, 14168 lncRNAs and 1209miRNAs (305 known and 904 novel miRNAs)were identifed.Compared yak with cattle, 4975 mRNAs, 3326 lncRNAs and 75 miRNAs were differentially expressed. 756 mRNAs, 346 lncRNAs and 83 miRNAs were found to be differentially expressed amongthree different altitude yaks(fold change≥2 and P-value<0.05). Conclusions:The differentially expressed genes were functionally enriched in long-chain fatty acid metabolic process and protein processing between yak and cattle, while the immune response and cell cycle were enriched among three different altitude yaks. Furthermore, the competing endogenous RNAs (ceRNAs) networks were identified to illustrate their roles.
