F-box proteins are key components of SCF (Skp1-Cullin1-F-box protein) complexes, which exert E3 ubiquitin ligase activity and participate in cell cycle and signal transduction. F-box proteins interact with Skp1 through the F-box domain and with proteins to be ubiquitinated through other interaction domains. We have characterized a novel muscle-specific(More)
Myostatin is a strong inhibitor of muscle growth, and its expression is increased in several types of muscle atrophy. However, whether or not myostatin expression is altered in muscle atrophy associated with type 1 diabetes (T1D) remains uncertain. In this study, we provided experimental evidence to show that myostatin mRNA increased in the early stage of(More)
Myostatin is a negative regulator of skeletal muscle growth and affects numerous genes expression involved in cell proliferation, differentiation and metabolism. However, the molecular mechanisms underlying myostatin-regulated genes expression remain to be elucidated. In this study, we showed that myostatin blocked the recruitment of p300 to the cyclin D1(More)
Myostatin (Mstn) is a secreted growth factor predominately expressed in skeletal muscle that negatively regulates skeletal muscle mass. Recent studies have indicated that loss function of myostatin not only increases muscle mass but also improves insulin sensitivity in vivo. In the present report, we demonstrated that myostatin regulates glucose metabolism(More)
BACKGROUND Limb-girdle muscular dystrophy (LGMD) is a group of heterogeneous muscular disorders with autosomal dominant and recessive inheritance, in which the pelvic or shoulder girdle musculature is predominantly or primarily involved. Although analysis of the defective proteins has shed some light onto their functions implicated in the etiology of LGMD,(More)
OBJECTIVE To detect polymorphisms of glucocorticoid receptor gene (NR3C1) in Chinese population with the technique of denaturing high-performance liquid chromatography (DHPLC). METHODS Genomic DNA was isolated from peripheral blood of 2 healthy volunteer doctors and umbilical cord blood of 62 normal neonates. All the NR3C1-coding exons along with their(More)
Dysregulation of microRNAs has been demonstrated to contribute to malignant progression of cancers, including hepatocellular carcinoma (HCC). MiR-24-3p was previously reported to be significantly upregulated in HCC. However, the potential role and mechanism of action of miR-24-3p in the initiation and progression of HCC remain largely unknown. Quantitative(More)
Previous studies have demonstrated that the genetic variations of glucocorticoid receptor gene (NR3C1) are associated with both familial steroid resistance and acquired steroid resistance in some diseases, such as Cushing's disease, leukemia, lupus nephritis, and female pseudohermaphroditism. In this study, we examined the genetic variations of NR3C1 in 35(More)
