Project description:Analysis of gene expression in both muscle and liver due to the lost of one copy of the gene ADCK2. Heterocygous mouse ADCK2(+/-) present an altered gene expression that explain the adult phenotype, including myopathy in muscle and steatosis and inflamation in liver.
Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to evaluate the effects of liver-specific E4BP4 overexpression under mouse albumin promoter on the muscle glucose and lipid metabolism. Methods: We generated transgenic mice (TG) with liver-specific E4BP4 overexpression. Gasrocnemius muscles were isolated at Zeitgeber Time (ZT) 0 or 12 from transgenic mice and WT littermates, and total RNA was extracted. Muscle RNA profiles were generated by deep sequencing for four groups with three mouse samples each. Results: There were no significant differences between WT and transgenic mice at both ZT0 and 12. Conclusions: Muscle metabolism was not altered at the transcription level by liver specific overexpression of E4BP4.
Project description:Gestational protein restriction is a model for low birth size. We hypothesized that taurine supplementation would protect against changes in newborn liver and muscle caused by a maternal low protein diet. Pregnant mouse dams were subjected to different diet schemes from day 1 of pregnancy until birth. Pups were killed following birth and liver and hindleg skeletal muscle taken out and frozen at -80C until analysis. Diet schemes: Normal Protein (20% casein; NP), Normal Protein + taurine (1% taurine supplementation in water ad libitum; NP+tau), Low Protein (8% casein; LP) and LP+tau The liver and muscle samples were normalized separately.
