Project description:Mouse tibialis anterior muscles were electroporated with Nr2f6-myc plasmid or pCMV6 empty vector in the contralateral leg. After 9 days, muscles were collected, and the RNA extracted and processed for microarray analysis.
Project description:This project contains proteomics data obtained from 8 weeks old tibialis anterior and psoas skeletal muscles from c57bl6 and BlaJ male mice.
Project description:We generated transgenic mice expressing constitutively SOCS-3 specifically in skeletal muscle. SOCS proteins are implicated in the negative regulation of various pathways including insulin signaling pathway. Our transgenic mice are predisposed to obesity and systemic insulin resistance compared to control mice. We used microarrays to detail the variations of gene expression in muscle from transgenic mice versus controls. Keywords: transgenic, tibialis anterior, SOCS-3
Project description:Proteomic study of tibialis anterior muscle harvested at 1 day and 7 days post-injection with novel polyurethane nanoparticles compared to water sham and non-injected controls
Project description:Genome-wide gene expression analysis on tibialis anterior muscle from 2-month-old nebulin SH3 domain deleted (Neb∆SH3) mice compared to wildtype. Total RNA was obtained from biological triplicates of tibialis anterior muscle from 2-month-old nebulin SH3 domain deleted (Neb∆SH3) mice compared to wildtype.
Project description:Transcription profiling of skeletal muscle (tibialis anterior) of 5-week-old male wild type and myostatin null mice given ad libitum access to 20ppm clenbuterol hydrochloride in drinking water or plain tap water for 2 weeks. The objective of the study was to determine overlap in the mechanisms of muscle hypertrophy of the two models.
Project description:Resistance training (RT) promotes muscle protein accretion and myofiber hypertrophy, driven by dynamic processes of protein synthesis and degradation. While molecular studies have focused on acute signalling or long-term hypertrophy and strength gains, a critical gap remains in understanding the intermediate processes of muscle adaptation. Acute signalling does not always correlate directly with long-term outcomes, highlighting the need for a time-course analysis of protein abundance and turnover rates. To address this, we utilised deuterium oxide labelling and peptide mass spectrometry to quantify absolute protein content and synthesis rates in skeletal muscle. A daily programmed resistance training regimen was applied to the rat tibialis anterior (TA) via electrical stimulation of the left hind limb for 10, 20, and 30 days (5 sets of 10 repetitions daily). Muscle samples from stimulated (Stim) and contralateral control (Ctrl) limbs were analysed, quantifying 658 protein abundances and 215 protein synthesis rates.
