Project description:All vertebrates have multiple genes encoding for different CASQ isoforms. Increasing interest has been focused on mammalian and human CASQ genes since mutations of both cardiac (CASQ2) and skeletal (CASQ1) isoforms cause different, and sometime severe, human pathologies Danio rerio (zebrafish) is a powerful model for studying function and mutations of human proteins. In this work expression, biochemical properties and cellular and sub-cellular localization of Danio rerio native CASQ isoforms are investigated. By quantitative PCR three mRNAs were detected in skeletal muscle and one mRNA in heart. Three zebrafish CASQs were identified by mass spectrometry and they share properties with mammalian skeletal and cardiac CASQs. Skeletal calsequestrins were found primarily, but not exclusively, at the sarcomere Z-line level where Terminal Cisternae of Sarcoplasmic reticulum are located.

Project description:Low temperatures may cause severe growth inhibition and mortality in fish. In order to understand the mechanism of cold tolerance, a transgenic zebrafish Tg (smyd1:m3ck) model was established to study the effect of energy homeostasis during cold stress. The muscle-specific promoter Smyd1 was used to express the carp muscle form III of creatine kinase (M3-CK), which maintained enzymatic activity at a relatively low temperature, in zebrafish skeletal muscle. In situ hybridization showed that M3-CK was expressed strongly in the skeletal muscle. When exposed to 13°C, Tg (smyd1:m3ck) fish maintained their swimming behavior, while the wild-type could not. Energy measurements showed that the concentration of ATP increased in Tg (smyd1:m3ck) versus wild-type fish at 28°C. After 2 h at 13°C, ATP concentrations were 2.16-fold higher in Tg (smyd1:m3ck) than in wild-type (P < 0.05). At 13°C, the ATP concentration in Tg (smyd1:m3ck) fish and wild-type fish was 63.3% and 20.0%, respectively, of that in wild-type fish at 28°C. Microarray analysis revealed differential expression of 1249 transcripts in Tg (smyd1:m3ck) versus wild-type fish under cold stress. Biological processes that were significantly overrepresented in this group included circadian rhythm, energy metabolism, lipid transport, and metabolism. These results are clues to understanding the mechanisms underlying temperature acclimation in fish.

Gene expression in triplicate samples of m3ck-13M-BM-0C, m3ck-28M-BM-0C, wt-13M-BM-0C, and wt-28M-BM-0C was assessed. Twelve microarray experiments were performed, each with three fish.

Project description:To assess the effects of histone deacetylase (HDAC) inhibitor, HDACi 4b, treatment on muscle function on a molecular level, we performed microarray analysis on skeletal muscle (gastrocnemius) samples from wt and N17182Q mice treated with the HDAC inhibitor 4b for 3 months (50 mg/kg; s.c. injection 3x weekly; n=4 per group). The transcriptome pattern in N17182Q mice compared to wt controls consisted of deficits in the expression of genes related to mitochondrial function and oxidative metabolism. In addition, we noted that numerous genes associated with basal contractile function were altered in HD N17182Q mice. These include genes related to the muscle contractile complex, Tnnt3 and Myh8, as well as several additional myosin genes: myosin heavy chain genes, Myh10 and Myh4, and myosin light chain genes, Myl1, Mylc2 and Mylk. These findings implicate deficits in the underlying contractile function in skeletal muscle from HD mice. Further, we found robust effects of 4b treatment on the expression of genes in skeletal muscle, with 556 genes showing significantly altered expression, at p<0.005, in 4b-treated N17182Q muscle compared to vehicle-treated control mice. n=4 vehicle-treated WT mice, n=5 HDACi 4b-treated WT mice, n=4 vehicle-treated N17182Q transgenic mice, and n=3 HDACi 4b-treated N17182Q transgenic mice.

Project description:Fluoride toxicity in multiple organs has been extensively reported in several decades of research. In-depth study coverage is available on teeth and bone tissues. But studies addressing skeletal muscle fluorosis are scanty. C57BL/6 mice were provided with sodium fluoride in drinking water for 60 days. Histological analysis, primary culture of skeletal muscle was performed. Protein expressions were analyzed by Immunocytochemistry, qRT-PCR, and western blotting techniques. Proteomic approach was considered to overview the entire proteome response. Exposure to sodium fluoride resulted in the loss of body weight in C57BL/6 mice. The compactness of the myofibre arrangement was distorted due to the treatment. Major reduction of contractile proteins such as actinin, troponin, and myosin further loss of mitochondrial proteins were confirmed by proteomic approach. Sodium fluoride treatment altered mitochondrial function. Further, loss of contractile proteins triggered skeletal muscle weakness.
