Myostatin is a transforming growth factor beta superfamily member and is known as an inhibitor of skeletal muscle cell proliferation and differentiation. Exposure to myostatin induces G1 phase cell cycle arrest. In this study, we demonstrated that myostatin down-regulates Cdk4 activity via promotion of cyclin D1 degradation. Overexpression of cyclin D1(More)
OBJECTIVE We examined trends in incidence of treatment for diabetes-related end-stage renal disease (ESRD) in the U.S. RESEARCH DESIGN AND METHODS Using the U.S. Renal Data System, we obtained the number of individuals having diabetes listed as primary diagnosis who initiated ESRD treatment between 1990 and 2006. Incidence was calculated using the(More)
IMPORTANCE Although the prevalence and incidence of diabetes have increased in the United States in recent decades, no studies have systematically examined long-term, national trends in the prevalence and incidence of diagnosed diabetes. OBJECTIVE To examine long-term trends in the prevalence and incidence of diagnosed diabetes to determine whether there(More)
Mitochondrial preproteins destined for the matrix are translocated by two channel-forming transport machineries, the translocase of the outer membrane and the presequence translocase of the inner membrane. The presequence translocase-associated protein import motor (PAM) contains four essential subunits: the matrix heat shock protein 70 (mtHsp70) and its(More)
Polypeptides in bee venom (PBV) produced a significant growth inhibition against SMMC-7721 human hepatoma cell line. Analysis of the mechanisms of cell death indicated that PBV induced an apoptotic cell death. SMMC-7721 cells exposed to PBV (10.0 microg mL(-1)) produced an insignificant morphological change. Analysis of the cytotoxicity with the MTT(More)
OBJECTIVE Childhood overweight and obesity have increased substantially in the past two decades, raising concerns about their psychosocial and cognitive consequences. We examined the associations between academic performance (AP), cognitive functioning (CF), and increased BMI in a nationally representative sample of children. METHODS AND PROCEDURES(More)
In mouse skeletal muscles, Pax7 uniquely marks muscle satellite cells and plays some important yet unknown functions at the perinatal stage. To elucidate its in vivo functions, we initiated a yeast two-hybrid screening to look for Pax7-interacting proteins and identified a previously uncharacterized Pax7- and Pax3-binding protein (Pax3/7BP). Pax3/7BP is a(More)
OBJECTIVE Patients with diabetes are at an increased risk for developing corneal complications and delayed wound healing. This study investigated the effects of high glucose on epidermal growth factor receptor (EGFR) signaling and on epithelial wound healing in the cornea. RESEARCH DESIGN AND METHODS Effects of high glucose on wound healing and on EGFR(More)
Transport of preproteins into the mitochondrial matrix requires the presequence translocase of the inner membrane (TIM23 complex) and the presequence translocase-associated motor (PAM). The motor consists of five essential subunits, the mitochondrial heat shock protein 70 (mtHsp70) and four cochaperones, the nucleotide exchange-factor Mge1, the(More)
In present study, a facile prepared nano-sized magnetic support was successfully synthesized. Then this support was applied for lipase immobilization using glutaraldehyde as a coupling agent. Experimental data showed that the immobilized lipase exhibited good thermal stability and reusability. The lipase loading amount and activity recovery were found to be(More)
