Project description:In this study, differentially expressed (DE)piRNAs of fresh and frozen-thawed sperm with different freeze tolerance compacity from giant panda and boar were evaluated. The results showed 1160 (22 down-regulated and 1138 up-regulated) and 384 (110 up-regulated and 274 down-regulated) differentially expressed (DE) piRNAs were identified in giant panda and boar sperm, respectively. Gene ontology (GO) enrichment analysis revealed that the target DE mRNAs of DE piRNAs were mainly enriched in biological regulation, cellular process and metabolic process in giant panda and boar sperm. Moreover, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis indicated that the target DE mRNAs of DE piRNAs were only distributed on DNA replication and cAMP signaling pathway in giant panda, but cAMP, cGMP and MAPK signaling pathway in boar sperm which were considered as part of olfactory transduction pathway.Conclusion:Olfactory transduction related pathways maybe contributed to different freeze tolerance compacity between giant panda and boar sperm, which will benefit to further understand the molecular mechanism of sperm cryoinjury and freezability.

Project description:Large White and Meishan pigs were either non-treated or injected with mammalian 1-24 ACTH (Immediate Synachten, Novartis France) at the dose of 250 µg per animal. Pigs were sacrificed either immediately after capture from their home cage (non-treated animals) or 1 hour following ACTH injection. Adrenal glands were immediately collected from pigs and frozen on dry ice and then stored at -80°C until RNA isolation. Keywords: stress response, adrenal, gene expression, pig

Project description:We identified 34,521 and 31,803 circRNAs in piglet (30 d) and adult (210 d) boar testis by high-throughput sequencing, respectively. Bioinformatics analysis revealed that these circRNAs are widely distributed on autosomes and sex chromosomes. Some of the host genes can generate multiple circRNAs. A total of 2,326 differentially expressed circRNAs (DECs) derived from 1,526 host genes were found in testicular development, of which 1,003 circRNAs were up-regulated in adult boar testes and 1,323 circRNAs were down-regulated. Furthermore, gene ontology (GO) analysis of host genes of DECs revealed that these circRNAs are mainly involved in regulating spermatogenesis, cilia motility, and hormone biosynthesis. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed that the DECs are markedly enriched to stem cell pluripotency regulation, tight junctions, adhesion junctions, and cAMP signaling pathway. These results indicate that circRNAs are abundantly expressed in boar testes and exhibit dynamic changes during testicular development.
