The purpose of this study was to identify novel marbling-related genes by comparison of the global gene expression in semitendinosus muscle of 15-month-old Limousin (LIM), Holstein-Friesian (HF) and Hereford (HER) bulls. Muscle of LIM was lean with low intramuscular fat (IMF) content (0.53%) unlike the marbled muscles of HER and HF characterized by higher(More)
Myostatin (GDF-8) is a key protein responsible for skeletal muscle growth and development, thus mutations in the mstn gene can have major economic and breeding consequences. The aim of the present study was to investigate myostatin gene expression and transcriptional profile in skeletal muscle of Holstein-Friesian (Black-and-White) bulls carrying a(More)
The molecular mechanism of the cell death-promoting effect of dexamethasone (Dex) was studied during myogenesis (10 days) in L6 muscle cells by making use of several indices such as cell viability (protein synthesis, mitochondrial respiration), mortality (DNA fragmentation, chromatin condensation, structural modifications) and immunocytochemical studies(More)
GDF8 (myostatin) is a unique cytokine strongly affecting the skeletal muscle phenotype in human and animals. The aim of the present study was to elucidate the molecular mechanism of myostatin influence on the differentiation of mouse C2C12 myoblasts, using the global-transcriptome analysis with the DNA microarray technique. Treatment with exogenous GDF8(More)
A cDNA microarray (18 263 probes) was used for transcriptome analysis of bovine skeletal muscle (m. semitendinosus) in 12-month-old bulls of the beef breed Limousin (LIM) and the typical dairy breed Holstein-Friesian (HF, used as a reference). We aimed to identify the genes whose expression may reflect the muscle phenotype of beef bulls. A comparison of(More)
The leucine metabolite β-hydroxy-β-methylbutyrate (HMB) has been studied by many researchers over the last two decades. In particular, the utility of HMB supplementation in animals has been shown in numerous studies, which have demonstrated enhanced body weight gain and carcass yield in slaughter animals; positive immunostimulatory effect; decreased(More)
Gamma-oryzanol (GO) is an abundant dietary antioxidant that is considered to have beneficial effects in cardiovascular disease, cancer and diabetes. Other potential properties of GO include inhibition of gastric acid secretion and decreased post-exercise muscle fatigue. GO is a unique mixture of triterpene alcohol and sterol ferulates present in rice bran(More)
Dexamethasone (Dex)-mediated cell death is associated with repression of survival factors (AP-1, c-myc, NF-kappaB). Dex suppressed the activity of genes encoding antioxidant enzymes leading to impaired viability and apoptotic cell death. These findings suggest that reactive oxygen species inhibit protein synthesis and amplify m-calpain-dependent(More)
The aim of the present study was to define the effect of TGF-beta1 on C2C12 myoblasts myogenesis. TGF-beta1 together with its receptor is a negative auto-paracrine regulator of myogenesis, which influences the proliferation, differentiation, and functions of muscle cells. TGF-beta1 exerts highly significant inhibitory effect on differentiation of C2C12(More)
The idea of the Internet of Things, which emerged in recent years, became one of the main fields of interest in industrial and academic research. The Constrained Application Protocol (CoAP) is one of the technologies aspiring to a standard in the IoT world. CoAP was designed to provide a low-overhead, machine-to-machine communication for constrained devices(More)
