Project description:Roles of small RNAs in the effects of nutrition on apoptosis and spermatogenesis in the adult testis
| PRJNA265167 | ENA
Project description:We tested whether the defects in spermatogenesis and increases in germ cell apoptosis that are induced by under-nutrition are associated with changes in mRNA expression and pre-mRNA alternative splicing in the testis. Groups of 8 male sheep were fed for a 10% increase or 10% decrease in body mass over 65 days. We identified 2,243 mRNAs, including TP53 and Claudin 11, that were differentially expressed in testis from underfed and well-fed sheep (FDR < 0.1), and found that their changes in expression were associated with germ cells, testis size, cell cycle and spermatogenesis variations. Furthermore, pairs of 269 mRNAs and 48 miRNAs were indentified based on target prediction and the negative regulatory effect of miRNAs on mRNA expression with functions involved in abnormal reproductive morphology, apoptosis and male infertility. Nutrition did not affect the total number of alternative splicing junctions, but affected 1,040 alternative splicing events (FDR < 0.05, ∆PSI > 10%). A total of 788 genes, including CREM, MAP2, HIPK3 and TRa2β, were differentially spliced between dietary treatments, with functions related to protein localization, cellular metabolic process, post-translational protein modification and spermatogenesis. In addition, three gene modules were positively correlated with spermatogenesis-related phenotypic traits and negatively related to apoptosis-related phenotypic traits. Among these gene modules, seven (CFLAR, PTPRC, F2R, MAP3K1, EPHA7, APP, BCAP31) were also differentially expressed between nutritional treatments, indicating their potential as markers of spermatogenesis or apoptosis. We conclude that under-nutrition causes changes in mRNAs and pre-mRNA alternative splicing that, at least partly, contribute to disrupted spermatogenesis and increased germ cell apoptosis.

Project description:Maternal nutrition induces gene expression changes in fetal muscle and adipose tissues in sheep
| PRJNA266236 | ENA
Project description:We have completed the high quality reference genome for domestic sheep (Oar v3.1) and performed a detailed survey of gene expression across different tissues. RNA-seq data of 7 tissue types from the reference female Texel and skin tissue from a Gansu alpine fine wool sheep were sequenced.

Project description:To elucidate the complex physiological process of testis development and spermatogenesis in Sika deer, this study evaluated the changes of mRNA profiles in the four developmental stages of testis the juvenile (1-year-old), adolescence (3-year-old), adult (5-year-old) and aged (10-year-old) stages. The results showed that total total of 23558 differentially expressed (DE) unigenes were obtained. 14918 (8413 up and 6505 down), 4988 (2453 up and 2535 down), 5681 (2929 up and 2752 down) DE unigenes were identified in 3-vs.1-, 5-vs.3- and 10-vs.5-year-old testes, respectively. By integrating mRNA expression profiles, we predicted 10790 mRNA-mRNA interaction sites. The target genes were enriched by GO and KEGG pathways to obtain DE mRNA (ALKBH5, Piwil, HIF1A, BRDT, etc.), which play an important role in testis development and spermatogenesis. The data show that DE mRNAs could regulate testis developmental and spermatogenesis through signaling pathways, including MAPK signaling pathway, p53 signaling pathway, PI3K-Akt signaling pathway, Hippo signaling pathway, etc. It provides a useful resource for future studies on the role of genes regulation in testis development and spermatogenesis.

The results showed that total total of 198 mature and 66 novel miRNAs were obtained. 88 (43 up and 45 down), 102 (44 up and 58 down), 54 (18 up and 36 down) DE miRNAs were identified in 3-vs.1-, 5-vs.3- and 10-vs.5-year-old testes, respectively. By integrating miRNA expression profiles, we predicted 69883 miRNA-mRNA interaction sites. The target genes were enriched by GO and KEGG pathways to obtain DE miRNA (miR-145, miR-140, miR-7, miR-26a, etc.), which play an important role in testis development and spermatogenesis. The data show that DE miRNAs could regulate testis developmental and spermatogenesis through signaling pathways, including MAPK signaling pathway, p53 signaling pathway, PI3K-Akt signaling pathway, Hippo signaling pathway, etc. It provides a useful resource for future studies on the role of miRNA regulation in testis development and spermatogenesis.
