Here, we aimed to systematically investigate the genetic regulatory mechanisms of hepatic steatosis in laying hens.Methods Ninety individuals with the most prominent characteristics were selected from 686 laying hens according to the accumulation of lipid droplets in the liver, and were graded into three groups, including the control, mild hepatic steatosis and severe hepatic steatosis groups. A combination of transcriptome, proteome, acetylome and lipidome analyses, along with bioinformatics analysis were used to screen the key biological processes, modifications and lipids associated with hepatic steatosis.Results The rationality of the hepatic steatosis grouping was verified through liver biochemical assays and RNA-seq. Hepatic steatosis was characterized by increased lipid deposition and multiple metabolic abnormalities. Integration of proteome and acetylome revealed that differentially expressed proteins(DEPs) interacted with differentially acetylated proteins(DAPs) and were involved in maintaining the metabolic balance in the liver. Acetylation alterations mainly occurred in the progression from mild to severe hepatic steatosis, i.e., the enzymes in the fatty acid oxidation and bile acid synthesis pathways were significantly less acetylated in severe hepatic steatosis group than that in mild group(P < 0.05). Lipidomics detected a variety of sphingolipids(SPs) and glycerophospholipids(GPs) were negatively correlated with hepatic steatosis(r ≤-0.5, P < 0.05). Furthermore, the severity of hepatic steatosis was associated with a decrease in cholesterol and bile acid synthesis and an increase in exogenous cholesterol transport.Conclusions In addition to acquiring a global and thorough picture of hepatic steatosis in laying hens, we were able to reveal the role of acetylation in hepatic steatosis and depict the changes in hepatic cholesterol metabolism. The findings provides a wealth of information to facilitate a deeper understanding of the pathophysiology of fatty liver and contributes to the development of therapeutic strategies.展开更多

文摘During seed germination,the cotton chaperone protein HSP24.7 regulates the release,from the mitochondrial electron transport chain,of reactive oxygen species(ROS),a stimulative signal regulating germination.The function of HSP24.7 during vegetative stages remains largely unknown.Here we propose that suppression of Gh HSP24.7 in cotton seedlings increases tolerance to heat and drought stress.Elevation of Gh HSP24.7 was found to be positively associated with endogenous levels of ROS.We identified a new client protein of Gh HSP24.7,cotton lysine deacetylase(Gh HDA14),which is involved in mitochondrial protein modification.Elevated levels of Gh HSP24.7 suppressed deacetylase activity in mitochondria,leading to increased acetylation of mitochondrial proteins enriched in the subunit of Ftype ATPase,V-type ATPase,and cytochrome C reductase,ultimately reducing leaf ATP content.Consequently,in combination with altered ROS content,Gh HSP24.7 transgenic lines were unable to coordinate stomatal closure under stress.The regulation circuit composed of Gh HSP24.7 and Gh HDA14 represents a post-translation level mechanism in plant abiotic stress responses that integrates the regulation of ROS and ATP.
