Project description:A comparative profile of miRNAs in livers during pigeon development was performed by using high-throughput sequencing. We identified known pigeon miRNAs, novel miRNAs, and miRNAs that are conserved in other birds and mammals.Our results expanded the repertoire of pigeon miRNAs and may be of help in better understanding the mechanism of squab’s rapid development from the perspective of liver development.

Project description:Swine confinement buildings (SCBs) represent workplaces with high biological air pollution. It is suspected that individual components of inhalable air are causatives of chronic respiratory disease that are regularly detected among workers. In order to understand the relationship between exposure and stress, the aim of this study was to develop a method to investigate the components of bioaerosols in more detail. For this purpose, bioaerosols from pig barns were collected on quartz filters from two exclusively housed pig types (porkers and gestating sows) and subsequently analyzed via a combinatorial approach of 16S rRNA amplicon sequencing and metaproteomics. The workflow helps to clarify diversity in bioaerosols from a taxonomic perspective, but also from a functional perspective.
Project description:A comparative profile of miRNAs in pre- and post-differentiated pigeon SMSCs (SMSC-1d and SMSC-5d) was performed by using high-throughput sequencing. We identified known porcine miRNAs, novel miRNAs, and miRNAs that are conserved in other birds and mammals. Our findings demonstrated that miRNAs are extensively involved in the differentiation of SMSCs in pigeons, and provide a valuable resource for the pigeon breeding.
Project description:The macula and fovea located at the optical centre of the retina make primate visual perception unique among mammals. Pigeon retina and the human macula share a number of structural and functional properties that justify introducing the former as a new model system for retina development. Comparative transcriptome analysis of the pigeon and chicken retinas at different embryonic stages was undertaken to uncover how transcriptomic patterns translate into functional differences between the two bird species. The study showed that the pigeon’s genetic programs underlying cell differentiation are postponed until the end of the period of cell proliferation. This allows the pigeon to build a retina that displays the structural and functional traits typical of primate macula and fovea.
