Project description:Pericytes(PCs) are mural cells embedded in the capillary basal lamina. Some PC populations exhibit multipotency, similar to mesenchymal stem cells. Here, the the process of adaptation was investigated by determining changes in transcript profiles when NG2 positive PCs were deleted. PC-deletion was induced by using NG2CreER(+/-)/diphtheria toxin flagment A(DTA) transgenic mice. Cre recombinase was induced by tamoxifen(Tam) treatment(intraperitoneally, 100mg/kg body weight per day) for 5days. Samples were collected at 1month after Tam treatment.
Project description:Analysis of soleus (SOL) muscle isolated from wildtype (WT) and Mettl21cLacZ/LacZ mice (KO). Results provide unbiased gene expression profile of SOL muscle after Mettl21c deletion.
Project description:We used phosphoproteomic profiling of slow-twitch (soleus, SOL) and fast-twitch (biceps femoris, BF) muscle to identify differences between these muscle types.
Project description:The effect of acetyl-L-carnitine (ALCAR) supplementation to hindlimb suspended rats has been analyzed in order to test whether this would promote the differentiation towards an oxidative phenotype of muscle fibers in soleus muscle and prevent the transformation of this slow tonic muscle towards a glycolytic, low-oxidative phenotype due to unloading condition. 3 month-old rats were daily supplemented with ALCAR concomitantly with hindlimb suspension. Validated microarray analysis for a broad range of muscle-relevant processes delineated an ALCAR-induced adjustment of the expression profile. In particular, transcript elevations of factors underlying oxidative metabolism in mitochondria and protein turnover by ribosomal and proteasomal components as well as an adaptation of voltage-gated ion channel expression were identified as an ALCAR response in soleus muscle. Keywords: ALCAR effect
Project description:Gene expression changes induced by acute skeletal muscle unloading, which leads to physiological changes including muscle atrophy, fibre-type switching, and loss of ability to transition between lipid and glucose as energy source (metabolic inflexibility), was investigated by hind-limb suspension (HLS) treatment of Male ICR mice (28–32 g body wt; Harlan, Indianapolis, IN). Agilent Whole Mouse Genome Oligo Microarrays were utilised to examine the effects of HLS on mRNA expression profiles of the soleus muscle and the gastrocnemius muscle in the hindlimbs of freely ambulating control and 24h HLS treated mice. Keywords: treatment vs control, tissue type comparison
