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:In recent years, the roles of microRNAs playing in the regulation of influenza viruses replication caused researchers' much attenion. However, much work focused on the interactions between human, mice or chicken microRNAs with human or avian influenza viruses rather than the interactions of swine microRNAs and swine influenza viruses. To investigate the roles of swine microRNAs playing in the regulation of swine influenza A virus replication, the microRNA microarray was performed to identify which swine microRNAs were involved in swine H1N1/2009 influenza A virus infection.

Project description:The effects of short-term confinement on gene expression profiles in blood were evaluated. Fourteen days confinement study was conducted 2 times. In each experiment, 8 male subjects were stayed in an isolation and confinement facility at Japan Aerospace Exploration Agency. DNA microarray of extracted RNA from whole blood samples revealed that the expression levels of 3,659 genes were significantly altered by the 14-day confinement. The changes in gene expression profiles were not exactly the same as those in response to the other stress conditions, such as chronic psychological stress and spaceflight. In particular, 7 genes, LIN9, AK125040.1, MGC45922, C9orf173-AS1, OR1P1P, KRTAP10-12, and ARFRP1, responded to the confinement prominently. Therefore, the analysis of expression levels of these genes might be useful to assess the stress responses of human body to the confinement. In addition, biological interpretation of the alteration of gene expression profiles with Ingenuity Pathway Analysis indicated that 14-day confinement stimulated various signaling related to proinflammation and leukocyte extravasation but suppressed apoptosis signaling. In agreement with the interpretation, the decrease of white blood cells in blood was confirmed during the confinement. On the other hand, red blood cells and platelets did not decrease. These results suggest that 14-day confinement is likely to induce shift of white blood cells from “the circulating pool” to “the marginated pool”.
Project description:Farm workers are at an increased risk for the development of acute and chronic lung inflammatory diseases from their everyday exposures to organic dust. Previous investigations have examined the inflammatory effects in mice from single and repetitive exposures to dust from swine confinement facilities, however, no study has explored these effects in a chronic model. To address this research gap, we established a chronic dust exposure mouse model of lung tumor-igenesis that was also used to measure the efficacy of omega-3 fatty acid-derived lipid mediators as therapeutics for mitigating these induced responses. Our results from these investigations are the first to evaluate the chronic inflammatory, and carcinogenic effects of these dusts, as well as identify a potential therapeutic strategy for mitigating the inflammatory effects by using an omega-3 fatty acid-derived bioactive lipid mediator.
Project description:The objective of the study was to characterize distinct endotypes of asthma related to damp and moldy buildings and to evaluate the potential molecular similarities with idiopathic environmental intolerance (IEI). The nasal biopsy transcriptome of 88 study subjects was profiled using samples obtained at baseline.
