Description
Consumption of a protein containing meal by a fasted animal promotes protein accretion in skeletal muscle, in part through leucine stimulation of protein synthesis and indirectly through repression of protein degradation mediated by its metabolite, a-ketoisocaproate. Mice lacking the mitochondrial branched-chain aminotransferase (BCATm/Bcat2), that interconverts leucine and a-ketoisocaproate, exhibit elevated protein turnover. Here, the transcriptomes of gastrocnemius muscle from BCATm knockout (KO) and wildtype mice were compared using Next Generation RNA-Sequencing (RNA-Seq) to identify potential adaptations associated with their persistently altered nutrient signaling. Statistically significant changes in the abundance of 1486/~39,010 genes were identified. Bioinformatics analysis of the RNA-Seq data indicated that pathways involved in protein synthesis (eIF2, mTOR, eIF4 and p70S6K pathways including 40S and 60S ribosomal proteins), protein breakdown (e.g., ubiquitin mediated), and muscle degeneration (apoptosis, atrophy, myopathy and cell death) were up-regulated. Also in agreement with our previous observations, the abundance of mRNAs associated with reduced body size, glycemia, plasma insulin, and lipid signaling pathways were observed in BCATm KO mice. Consistently, genes encoding anaerobic and/or oxidative metabolism of carbohydrate, fatty acids and BCAAs were modestly but systematically reduced. Although there was no indication that muscle fiber type was different between KO and wildtype mice, a difference in the abundance of mRNAs associated with a muscular dystrophy phenotype was observed, consistent with the published exercise intolerance of these mice. The results suggest transcriptional adaptations occur in BCATm KO mice that along with altered nutrient signaling may contribute to their previously reported protein turnover, metabolic and exercise phenotypes. Overall design: Comparison of wildtype and BCATm KO gastrocnemius biological replicates

Description
The purpose of this study was to examined the acute actions of the second generation antipsychotic (SGA), olanzapine, on skeletal muscle (gastrocnemius) of Sprague Dawley Rats. SGAs cause metabolic side effects including leading to metabolic inflexibility, hyperglycemia, adiposity and diabetes. These effects are preceded by glucose intolerance and increased FFA flux and metabolism in peripheral tissues. Skeletal muscle is a likely target of glucose intolerance, therefore understanding how olanzapine affects the skeletal muscle transcriptome could elucidate approaches for mitigating these side effects. Male Sprague-Dawley rats freely fed on normal chow with comparable body weights (vehicle: 373±9g, olanzapine: 388±11g, p=0.34) were infused with vehicle or olanzapine for 24h using a dosing regimen leading to mild hyperglycemia (vehicle, 98±2mg/dl; olanzapine 127±4mg/dl, p=0.0023). For the olanzapine group, the venous catheter was attached to a syringe pump (Model NE-300) filled with olanzapine (Dr. Reddy’s Laboratories Ltd, Hyderabad, India) in sterile saline (infusion: 1mg/100g BW loading dose for 0.5h and then 0.04mg/100g/h continuously for 23.5h). Gastrocnemius was then surgically removed under isoflurane anesthesia (carried with 100% O2), and frozen between two aluminum blocks cooled to the temperature of liquid nitrogen and then stored at -80oC until RNA was isolated. With anesthesia gas flow continuing, the animals were euthanized by cutting the diaphram and removing the heart. The mRNA was isolated from from these muscles and used for RNA-Seq followed by alignment of the data with the rat genome assembly 5.0. To determine significant differences in FPKM values between control and olanzapine groups, the DEGexp function of the DEGseq 1.18.0 R package was used with the Likelihood Ratio Test (LRT) and default parameters. In the uploaded excel file, P values with p<0.05 and p<0.001 are shown for each row in different columns indicated by the number 1. The value 0 indicates the row is not significantly different. Overall design: Comparison of vehicle (n=3) and olanzapine infused (n=3) rats.

Description
The hallmark of the cerebral neocortex is its organization into six distinct layers, each containing a characteristic set of neural cell types and synaptic connections. The transcriptional events involved in laminar development and function still remain elusive. Here we employed deep sequencing of mRNA and small RNA species to gain insights into transcriptional differences among layers and their temporal dynamics during postnatal development of the mouse primary somatosensory neocortex. A number of novel coding and noncoding transcripts were identified with specific spatiotemporal expression and splicing patterns across layers or time points. We also identified gene co-expression networks associated with distinct biological processes and transcriptional sharing between distinct biological processes, as well as, potential microRNA and mRNA interactions. Overall, this study provides an integrated view of the laminar and temporal expression dynamics of coding and noncoding transcripts in the mouse neocortex and a resource for future studies of neurodevelopment and transcriptome.
