Project description:GCs were collected from HFs and AFs , to use second-generation high-throughput sequencing for whole-transcriptome analysis, respectively. In total, 1861 and 1075 mRNAs, 159 and 24 miRNAs, 123 and 100 lncRNAs, and 58 and 54 circRNAs were identified to be differentially expressed (DE) in up-regulated and down-regulated. Enrichment of functions and signaling pathways of the DEgenes showed that most of DEmRNAs and targets of DEmiRNAs, DElncRNAs and DEcricRNAs were annotated to the categories of ‘PI3K-Akt signaling pathway’, ‘ECM-receptor interaction’, ‘Focal adhesion’, ‘mTOR signaling pathway ’ ‘TGF-beta signaling pathway’, ‘Rap1 signaling pathway’, and ‘Estrogen signaling pathway’. The ceRNA (competing endogenous RNA) network was constructed based on ceRNA theory further revealed regulatory roles of these DERNAs in granulosa cells of buffalo atretic follicles. A large number of mRNAs, lncRNAs, circRNAs, and miRNAs in buffalo granulosa were altered in healthy and atretic follicles, which may play crucial roles in atretic of buffalo follicles through the ceRNA regulatory network.
Project description:Background: Background: In bovines, the development and growth of adipose involves many physiological processes and plays an extremely important role in the quality of beef, however, the regulatory mechanisms underlying the differences in meat quality are largely unknown. Therefore, a buffalo adipose transcriptome analysis was performed to compare gene expression profiles between different growth stages. Results: Finally, a total of 21,693 mRNAs were obtained, of which 2506 were significantly differentially expressed mRNAs in the two groups, 9494 lncRNAs, a total of 281 lncRNAs and 2506 mRNAs showed significant differential expression patterns and 14990 between the two buffaloes CircRNA, 252 circRNAs were significantly differentially expressed between young and adult buffalo.
