Project description:Cattle-yak is the hybrid offspring of yak and cattle. It has obvious heterosis in production performance, but the male sterility of cattle-yak has always been the focus of attention. Studies have shown that non-coding RNA is involved in the regulation of spermatogenesis. We comprehensively compared the testicular transcription profiles of cattle, yak and cattle-yak. More DEGs, DECs and DEMs were found in the intersection of the two comparison groups of cattle and cattle-yak, yak and cattle-yak, with 4,968, 360 and 59, respectively. The DEGs of cattle-yak, cattle and yak were mainly enriched in biological processes such as spermatogenesis, male gamete generation and sexual reproduction. At the same time, GO and KEGG analysis suggested that DECs host genes and DEMs source genes were also involved in the regulation of spermatogenesis. The construction of potential ceRNA networks found that some differentially expressed ncRNAs may be involved in the regulation of genes related to testicular spermatogenesis, including miR-423-5p, miR-449b, miR-34b/c, miR-15b, etc., as well as unreported miR-6123, miR-1306 and some miRNA and circRNA interaction pairs. This study provides a reference for further study on the mechanism of male sterility in cattle-yak.

Project description:This study used yak and cattle-yak testes from different developmental stages as materials to construct a complete translation map of the testes, and integrated transcriptome and translation results to explore gene expression changes during the sexual maturation process of yak testes. This study utilized Ribo seq technology to construct a transcriptome map of yak testicular development, revealing that the expression of genes related to spermatogenesis is specifically translated and regulated at different developmental stages. In addition, many unknown open reading frames (ORFs) in the testes have been newly identified.

Project description:RNA sequence analysis identified a total of 8473 differentially expressed genes (DEGs) (3580 up-regulated, 4893 down-regulated), and GO annotation and KEGG enrichment of differential genes found that DEGS were mostly related to spermatogenesis and apoptosis. Among them, Spermatogonia stem cell (SSCs) marker genes (ITGA5, Gfra1, CD9, SOHLH1, SALL4, ID4 and FOXO1) were significantly up-regulated, differentiation spermatogenic cell marker genes (KIT, UCHL1, Ccna1, TNP1 and TXNDC2) were significantly down-regulated, and genes involved in apoptosis (Fas, CTSK, CTSB, CTSC, CTSO, caspase 3, caspase6, and caspase) were significantly up-regulated. Furthermore, the AS events in cattle-yak are significantly lower than in yak, we speculate that lack of mRNA and protein subtypes may lead to spermatogenic arrest in yak testicle.

Project description:N6-methyladenosine (m6A) is the most prominent mRNA modification in eukaryotes, and its potential regulatory role has recently been identified in mammals, plants, and yeast. However, how m6A methylation regulates spermatogenesis remains unknown. In this study, cattle-yak testis tissue was used as the experimental material, and the m6A map was generated through preliminary experiments and methylated RNA immunoprecipitation sequencing. Only spermatogonia and Sertoli cells were observed in cattle-yak testis tissue. Experiments examining the expression of methylation-related enzymes and the overall methylation level showed that the methylation level in the testis of the cattle-yak was slightly lower than that of the sexually mature yak, but significantly higher than that of the pre-sexually mature yak. Annotation analysis indicated that differentially methylated peaks were most frequently concentrated in exonic regions, followed by 3'UTR and finally 5'UTR regions. Through enrichment analysis of differentially expressed genes and differentially methylated corresponding genes, GO analysis of T-vs-Y group mainly involved spermatogenesis, including cytoskeleton, actin binding, etc. KEGG analysis showed that the differential genes were mainly enriched in actin cytoskeleton regulation and MAPK signaling pathway. GO analysis of the T-vs-M group mainly involved protein ubiquitination, ubiquitin ligase complexes, ubiquitin-dependent protein catabolism and endocytosis. KEGG analysis mainly involved apoptosis and Fanconi anemia pathways. This study will lay the foundation for elucidating the molecular mechanism of m6A in male sterility of cattle-yak.

Project description:Sex condition has been demonstrated to alter meat quality and sex is a major factor that affects the fatty acid composition of lipids of carcass dissectible or intramuscular depot fats. But the possible genetic molecular mechanism of gender causing meat quality differences is not well defined. Qinchuan cattle, Qinghai yak and Guangxi buffalo are three typical indigenous species of cattle in China. Obivious differences of meat quality exist among the three species of cattle. Few studies have been conducted to elucidate the muscle tissue expression of genes involved in pathways and mechanisms leading to meat quality differences beyond the phenotype properties of beef. Bovine Genome Arrays were used to construct muscle expression profiles of the longuissimus dorsi from Qinchuan cattle at 36 months and screen differentially expressed genes in the longuissimus dorsi muscle tissues among different genders of Qinchuan cattle, between Qinchuan cattle and Qinghai yak, and between Qinchuan cattle and Guangxi buffalo.
