Gene expression altered by high-fructose diet feeding and Chrebp deficiency

Project description:Epidemiologic and animal studies implicate overconsumption of fructose in the development of non-alcoholic fatty liver disease, but the molecular mechanisms underlying fructose-induced chronic liver diseases remains largely unknown. We present evidence supporting the essential function of the lipogenic transcription factor ChREBP in mediating adaptation response to fructose and protecting against fructose-induced hepatotoxicity. High-fructose diet (HFrD) activates hepatic lipogenesis via a ChREBP-dependent manner in wildtype mice, while inducing steatohepatitis in Chrebp-KO mice. In Chrebp-KO mouse livers, HFrD reduces levels of molecular chaperones and activates the CHOP-dependent unfolded protein response, whereas administration of chemical chaperone or Chop shRNA rescues liver injury. Gene expression profiling revealed elevated expression of cholesterol biosynthesis genes in Chrebp-KO livers after HFrD, in parallel with increased abundance of nuclear SREBP2. genes expression were compared between livers of wildtype mice fed 70%-fructose-diet v.s. regular chow, and between livers of Chrebp-/- mice v.s. wildtype mice fed 70%-fructose-diet.

Effect ofhepatocyte-specific Chrebp knockout on model of high-fructose diet during pregnancy

Project description:During pregnancy, a high-fructose diet (HFrD) exacerbates gestational insulin resistance and is associated with an increased risk of gestational diabetes. The relationship between liver ChREBP and gestational insulin resistance remains unknown. To address this question, we fed pregnant hChrebp-KO mice and wild-type mice a high-fructose diet, and on the 17th day of pregnancy, we extracted liver tissue from the mice and conducted comparative transcriptomic analysis to elucidate the role of liver ChREBP in gestational insulin resistance."

Expression data of liver with ChREBP gene knockout from mice fed with 60% sucrose diet for 1 week.

Project description:Carbohydrate response element binding protein (ChREBP) is one of the major transcription factors regulating carbohydrate metabolism and lipogenesis.It expresses highly in several tissues including liver, adipose tissue, small intestine,kidney and muscles. Mice with global knockout of ChREBP exhibit intolerance to carbohydrate including glucose and fructose. However, the exact role of liver ChREBP in high carbohydrate stress is not well defined. We used microarrays to exame the changes of gene expression pfofile upon high sucrose (50% glucose and 50% fructose) stress when liver ChREBP was deleted.

Activation of skeletal ChREBP increases IMFlevel in mice and Broiler Chickens

Project description:Intramuscular fat (IMF) content is one of the key factors affecting meat quality. Carbohydrate response element binding protein (ChREBP) can promote glucose metabolism and fat synthesis by activating the expression of glycolysis and lipogenesis-related genes, but its function and regulatory mechanism in IMF are still unclear. This study evaluated the correlation between TG content and ChREBP expression level in muscles of different species to reveal the relationship between ChREBP and IMF. RNA-seq analysis showed that overexpressing ChREBP in C2C12 cells can significantly up-regulate fatty acid synthesis pathways, while significantly down-regulate the expression levels of muscle development pathways and related genes. In vivo, we found that overexpression of ChREBP or activation by fructose significantly increased the triglyceride content of the tibialis anterior muscle (TA) and the IMF content of yellow feather chicken leg and breast muscle in mice. And lipidomics data also found that feeding fructose can change the lipid composition of yellow feather broiler breast muscle and improve the flavor substances. This study demonstrated that ChREBP is a key gene regulating IMF deposition, providing a new target for genetic selection and nutritional regulation of IMF content.

RNA-sequencing analysis of liver tissue from mice subjected to high-fructose or normal diets during pregnancy.

Project description:During pregnancy, a high-fructose diet (HFrD) exacerbates gestational insulin resistance and is associated with an increased risk of gestational diabetes. The relationship between liver ChREBP and gestational insulin resistance remains elusive. To address this question, we fed pregnant mice either a high-fructose diet or a normal diet. On the 17th day of pregnancy, we extracted liver tissue from the mice and conducted comparative transcriptomic analysis to elucidate the alterations in liver ChREBP during gestational insulin resistance.

Proline hydroxylation of ChREBP

Project description:This project investigated proline hydroxylation of ChREBP. Proline hydroxylation was investigated in flag-IP enriched protein extracts from ChREBP-flag overexpressing HEK293 cells (A) and in ChREBP-IP enriched mouse liver protein (male, C57BL6/J) (B).
