Project description:Utilizing glycerol and cardiotoxin (CTX) injections in the tibialis anterior muscles of M. musculus provides models of skeletal muscle damages followed by skeletal muscle regeneration. In particular, glycerol-induced muscle regeneration is known to be associated with ectopic adipogenesis. We characterized genome-wide expression profiles of tibialis anterior muscles from wild-type mice injured by either glycerol or CTX injection. Our goal was to detect gene expression changes during the time course of glycerol-induced and CTX-induced muscle regeneration models, that can lead to ectopic adipocyte accumulation. Tibialis anterior muscle of 12 week old wildtype C57BL/6J male mice injected i.m with either glycerol or CTX were collected 3, 7, 14 or 21 days after injection. 6 biological replicates were used for each time points. Please note that a few replicate samples did not pass QC test, thus, were removed from the submission. Unchallenged tibialis anterior muscles from a group of 5 wildtype C57BL/6J mice were also as a control. Total RNA was extracted, QCed and hybridized to Affymetrix microarrays.

Project description:Mice had a volumetric muscle loss (VML) injury inflicted on their left tibialis anterior (TA), while the right tibialis anterior was left uninjured as a control. Mice were split into groups based on how long post injury the muscles were harvested (4, 7, 11 and 15 days) Tissue samples were shipped to BGI for RNA-seq and then gene expression profiling analysis was performed using data obtained from RNA-seq from mouse tibialis anterior muscles.
Project description:To investigate the role of the circadian clock gene Bmal1 in skeletal muscle, we compared the circadian transcriptomes of fast tibialis anterior (TA) and slow soleus (SOL) skeletal muscles from muscle-specific Bmal1 KO (mKO) and their control Cre- littermates (Ctrl). Keyword: Circadian Transcriptome, time course
Project description:This project includes RNA-sequencing data from human FSHD and control skeletal muscle biopsies. This project includes data from 28 FSHD patients (total 37 samples, including vastus lateralis and tibialis anterior muscles) and 12 control individuals (total 24 samples, including vastus lateralis and tibialis anterior muscles).

Project description:Mice were electrically stimulated by implanting a pacer. The hindlimb muscles received low frequency stimulation for three hours and the tibialis anterior muscle was harvested at different time points after the stimulation. Sham operated control mice were included in the experiment. mRNA was pooled from 6 mice at each time point and hybridized to the arrays together with mRNA from untreated mice (reference). Keywords: time-course

Keyword: Circadian Transcriptome, time course 72 samples were analyzed, comprised of 4 experimental groups (Ctrl SOL, mKO SOL, Ctrl TA, mKO TA), with 3 biological replicates for each time point sampled every 4 hours for 24 hours. SOL and TA muscles were collected from the same animals, as indicated by Source Animal ID data column
Project description:PGC1b transgenic mice were generated to selectively over-express PGC1b in skeletal muscles using human skeletal alpha-actin gene promoter. The gene expression profiles were collected from Tibialis anterior (TA) muscles of wild type (WT) and PGC1b transgenic (TG) mice. Tibialis anterior muscles from three month old WT and PGC1b transgenic male mice.
