Project description:Penicillium citrinum X9-4, which was isolated from infected grapes by our laboratory, produced the highest amount of OTA at pH 5 in culture media, and toxin-production was restrained under acidic environment (pH 3). It revealed the possible mechanism of OTA biosynthesis and metabolic regulation in P. citrinum by transcriptomics, and investigated the reason of OTA biosynthesis was restrained in P. citrinum when cultured under acidic environment.
Project description:Purpose: Trichloroethylene (TCE) and tetrachloroethylene (PCE) are ubiquitous environmental contaminants and occupational health hazards. The goals of this study were to establish the common and differing transcriptional effects of TCE and PCE. This study examined liver and kidney effects of TCE and PCE in a dose-response study design. Methods: Equi-molar doses of TCE (24, 80, 240, 800 mg/kg) or PE (30, 100, 300, 1,000 mg/kg) were administered by gavage in aqueous vehicle to male B6C3F1/J mice. Tissues were collected 24 hrs after exposure. Trichloroacetic acid (TCA), a major oxidative metabolite of both compounds, was measured and RNA sequencing was performed on liver and kidney samples, with ~30 samples for each organ (29 after QC). Results: Most dose-responsive pathways were common among chemicals/tissues, with the strongest effect on peroxisomal beta-oxidation. Effects on liver and kidney mitochondria-related pathways were notably unique to PCE. Tissue-specific acute transcriptional effects of TCE and PCE occurred at human equivalent doses comparable to those for apical effects. Conclusions: Our study is the first RNA-Seq transcriptional study of TCE vs. PCE in both liver and kidney, enabling a detailed comparison of the chemicals and effects on different organs. Our results show strong commonalities of effects, although PCE shows stronger transcriptional responses than TCE for the same equimolar doses.
Project description:We use RNA-Seq to investigate gene expression differences in response to saltwater exposure by the larval stages of the obligate freshwater mosquito Anopheles coluzzii (formerly An. gambiae "M" form), and the euryhaline An. merus. After rearing in freshwater, both young and old larval instars of each species were briefly (6 h) exposed to either saltwater (SW) or freshwater (FW) conditions to test the impact of salinity on mRNA levels.
Project description:Feed additives aiming to improve gastrointestinal health are frequently supplied to piglets after weaning but might be more effective when administered before weaning. In this period, feed additives can either be administered directly to neonates, or indirectly via sow’s feed. It is yet unknown what the effect of the administration route is on gut functionality and health. Therefore, we compared the effect of different dietary interventions on gut functionality after maternal administration (lactation feed) to the neonatal administration route (oral gavage). These feed interventions included medium chain fatty acids (MCFA), beta-glucans (BG), and galacto-oligosaccharides (GOS). We measured intestinal gene expression and microbiota composition after birth (d1) and after weaning (d31). Our results show that the type of intervention and the administration route influence gut functionality (microbiome and gene expression profiles). MCFA administration led to a more differentially orchestrated response when comparing the neonatal and maternal administration route then the other two additives, indicating the route of administration of the feed interventions is determinative for the outcome. This implies that for each nutritional intervention in early life of a pig the optimal route of administration needs to be determined.
