Project description:Reef-building corals play an important role in the marine ecosystem, and analyzing their proteomes from a structural perspective will exert positive effects on exploring their biology. Here we integrated mass spectrometry with newly published AI systems to obtain digital structural proteomes of dominant reef-building corals.

Project description:Unraveling the Impact of Genome Assembly on Bacterial Typing: A One Health Perspective
Project description:Aconitate decarboxylase 1 (ACOD1) is the enzyme synthesizing itaconate, an immuno-regulatory metabolite tuning host-pathogen interactions. Such functions are achieved by affecting metabolic pathways regulating inflammation and microbe survival. However, at the whole-body level, metabolic roles of itaconate remain largely unresolved. By using multiomics-integrated approaches, here we show that ACOD1 responds to high-fat diet consumption in mice by promoting gut microbiota alterations supporting metabolic disease. Genetic disruption of itaconate biosynthesis protects mice against obesity, alterations in glucose homeostasis and liver metabolic dysfunctions by decreasing meta-inflammatory responses to dietary lipid overload. Mechanistically, fecal metagenomics and microbiota transplantation experiments demonstrate such effects are dependent on an amelioration of the intestinal ecosystem composition, skewed by high-fat diet feeding towards obesogenic phenotype. In particular, unbiased fecal microbiota profiling and axenic culture experiments point towards a primary role for itaconate in inhibiting growth of Bacteroidaceae and Bacteroides, family and genus of Bacteroidetes phylum, the major gut microbial taxon associated with metabolic health. Specularly to the effects imposed by Acod1 deficiency on fecal microbiota, oral itaconate consumption enhances diet-induced gut dysbiosis and associated obesogenic responses in mice. Unveiling an unrecognized role of itaconate, either endogenously produced or exogenously administered, in supporting microbiota alterations underlying diet-induced obesity in mice, our study points ACOD1 as a target against inflammatory consequences of overnutrition.

Project description:High risk clones of Klebsiella pneumoniae resistant to broad spectrum Beta-lactams: A One Health perspective
Project description:Esophageal cancer is one of the most serious health problems globally because of its high incidence and mortality rate. Cisplatin (CDDP) is the primary treatment but limited by the drug resistance. However, the mechanism of cisplatin resistance remains unclear. Herein, the CDDP-resistant cell line TE-1/CDDP was established to compared with TE-1, the expression profiles of circRNAs mRNA and lncRNA were compared between TE-1/CDDP and TE-1 using microarray analysis, and used this as a basis for exploring possible mechanisms of drug resistance in genes such as HDAC9.
