To understand whether any human-specific new genes may be associated with human brain functions, we computationally screened the genetic vulnerable factors identified through Genome-Wide Association Studies and linkage analyses of nicotine addiction and found one human-specific de novo protein-coding gene, FLJ33706 (alternative gene symbol C20orf203).(More)
An inexorable loss of terminally differentiated heart muscle cells is a crucial causal factor for heart failure. Here, we have provided several lines of evidence to demonstrate that mitofusin-2 (Mfn-2; also called hyperplasia suppressor gene), a member of the mitofusin family, is a major determinant of oxidative stress-mediated cardiomyocyte apoptosis.(More)
Recent studies of adrenoceptors have revealed subtype-specific signaling, promiscuous G-protein coupling, time-dependent switching of intracellular signaling pathways, intermolecular interactions within or between adrenoceptor subfamilies, and G-protein-independent signaling pathways. These findings have extended the classical linear paradigm of(More)
Circulating endothelial progenitor cells (EPCs) have a critical role in endothelial maintenance and repair. Apolipoprotein A-I mimetic peptide D-4F has been shown to posses anti-atherogenic properties via sequestration of oxidized phospholipids, induction of remodeling of high density lipoprotein and promotion of cholesterol efflux from macrophage-derived(More)
PURPOSE To examine the effectiveness of threshold and polarized models in the training organization of Chinese top-level sprint speed skaters using a 2-y quasi-experimental design. METHODS Two years (2004-05 and 2005-06 seasons) of the Chinese national speed-skating team's daily training load (N = 9; 5 men, 23.6 ± 1.7 y, weight 76.6 ± 4.1 kg, competitive(More)
Mitsugumin 53 (MG53), a muscle-specific TRIM family protein, is an essential component of the cell membrane repair machinery. Here, we examined the translational value of targeting MG53 function in tissue repair and regenerative medicine. Although native MG53 protein is principally restricted to skeletal and cardiac muscle tissues, beneficial effects that(More)
Large conductance Ca(2+)-activated K(+) channels (BK(Ca)) play a critical role in blood pressure regulation by tuning the vascular smooth muscle tone, and hyposensitivity of BK(Ca) to Ca(2+) sparks resulting from its altered beta1 subunit stoichiometry underlies vasoconstriction in animal models of hypertension. Here we demonstrate hypersensitivity of(More)
RATIONALE Rad (Ras associated with diabetes) GTPase, a monomeric small G protein, binds to Ca(v)beta subunit of the L-type Ca(2+) channel (LCC) and thereby regulates LCC trafficking and activity. Emerging evidence suggests that Rad is an important player in cardiac arrhythmogenesis and hypertrophic remodeling. However, whether and how Rad involves in the(More)
Reebok Core Boards (RCB) used as a platform in training provide an unstable environment for resistance training. The objective of this study was to examine the effect of unstable surface on muscle electromyographic (EMG) activities during a deep squat task. Thirteen male subjects participated in the study. Electromyographic activities of soleus (SO), vastus(More)
Repair of injury to the plasma membrane is an essential mechanism for maintenance of cellular homeostasis and integrity that involves coordinated movement of intracellular vesicles to membrane injury sites to facilitate patch formation. We have previously identified MG53 as an essential component of the cell membrane repair machinery. In order for MG53 and(More)
