Project description:Specific pathogen free wild-type C57Bl/6 male mice fed ketogenic diet (Bio-Serv AIN-76-A) for 4 weeks Keywords: RNA Expression Array Hearts from 12 week-old mice that were maintained on a standard polysacchardide-rich chow until the age of 8 weeks, at which time they were switched to a ketogenic diet (ad libitum) and maintained for 4 additional weeks prior to collection of tissues
Project description:To investigate the translatome in the pancreatic tumor inresponse to ketogenidc diet and the combination of ketogenic diet with an inhibitor targeting eIF4E phosphorylation. We generated pancreatic tumor xenograftmice model, treated mice with regular chow, ketogenic diet or ketogenic diet with eFT508, an inhibitor targeting eIF4E phosphorylation. Then we performed Poly-RNAseq on the tumor isolated from mice upon different treatments.
Project description:Diets influence metabolism and susceptibility to disease. We have previously demonstrated that a ketogenic diet alleviates cardiac pathology, with its cardioprotective effects linked to increased lysine acetylation in the heart. To identify acetylated proteins associated with this diet, we conducted a proteomic analysis using liquid chromatography-tandem mass spectrometry in the hearts of mice fed either a ketogenic diet or a normal chow diet under hypertension. We identified 966 acetylated peptides corresponding to 320 acetylated proteins in the hearts of mice fed a normal chow diet (group A), while 1597 acetylated peptides corresponding to 425 acetylated proteins were identified in the hearts of mice fed a ketogenic diet (group M).
Project description:To investigate the translatome in the ketogenic diet fed condition and the role of phosphoralated eIF4E in it We performed polysome sequencing on chow fed and 24h ketogenic diet fed wild type mice and chow fed eIF4E S209A/S209A mice
Project description:Analysis of liver gene transcription during feeding of a ketogenic diet. Ketogenic diets may alter physiologic and metabolic profiles in a direction that favors weight loss. C57BL/6J mice were maintained for six weeks on either chow or ketogenic diet. Mice eating KD had lower weights, 90% reduction in insulin levels and increased energy expenditure compared to animals fed chow. Despite consumption of a very high fat diet serum lipids remained normal. Here we show that consumption of KD shifted liver metabolism to drastically increased fatty acid oxidation. Concurrently, expression of genes involved in fatty acid synthesis were markedly suppressed. Reference: A high fat, ketogenic diet induces a unique metabolic state in mice.

Experiment Overall Design: Eight week old C57BL/6 mice were fed either chow (Labdiet 5008, Pharmserv) or KD (F3666, Bio-Serv) for six weeks. Livers were harvested in the morning in ad lib fed animals. Total RNA from 2-3 animals in each group was used for Affymetrix analysis.
