Adrenomedullin is a potent vasodilator peptide secreted by vascular endothelial and smooth muscle cells. Adrenomedullin stimulates the proliferation of quiescent rat vascular smooth muscle cells (VSMCs) via p42/p44 ERK/MAP kinase activation. Recently, receptor-activity-modifying proteins (RAMPs) have been shown to transport calcitonin-receptor-like-receptor(More)
We have studied whether activation of cell adhesion kinase beta (CAKbeta) is involved in stretch-induced signaling pathway in cultured rat vascular smooth muscle cells. Cyclic stretch (1 Hz) induced a rapid (within 1 min) phosphorylation of CAKbeta, whose effect was time and strength dependent. Both Ca(2+) and Na(+) ionophores (A23187 and monensin)(More)
RATIONALE Arginine methylation by protein N-arginine methyltransferases (PRMTs) is an important posttranslational modification in the regulation of protein signaling. PRMT2 contains a highly conserved catalytic Ado-Met binding domain, but the enzymatic function of PRMT2 with respect to methylation is unknown. The JAK-STAT pathway is proposed to be regulated(More)
Insulin signaling in skeletal L6 myotubes is known to be affected by arginine methylation catalyzed by protein N-arginine methyltransferase 1 (PRMT1), however, the mechanism by which this occurs has not yet been defined. This study aimed to determine the exact substrate involved in the methylation and regulating insulin signaling in cells. Insulin enhanced(More)
AIMS Arginine methylation catalyzed by protein N-arginine methyltransferase (PRMT) 1 is implicated in a variety of cellular processes, although the potential role of PRMT1-mediated methylation in glucose intolerance has not been defined. This study aims to investigate whether alteration of PRMT1 activity contributes to the clinical features of type 2(More)
BACKGROUND Asymmetric NG,NG-dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthase, is regulated by the enzymatic participants of synthetic and metabolic processes, i.e., type I protein N-arginine methyltransferase (PRMT) and dimethylarginine dimethylaminohydrolase (DDAH). Previous reports have demonstrated that circulating ADMA levels(More)
A 44-year-old male was pointed out liver function abnormality by medical check-up. Blood examination and computed tomography showed liver cirrhosis. Then, he was referred to our hospital for further examination. After blood test, viral markers revealed previous infection of hepatitis B virus (HBV). We estimated the etiology of his liver disease as previous(More)
UNLABELLED A 45-year-old female was referred for endocrine evaluation of an incidental mass (31×24 mm in diameter) on the right adrenal gland. The patient was normotensive and nondiabetic, and had no history of generalised obesity (body weight, 46 kg at 20 years of age and 51.2 kg on admission); however, her waist-to-hip ratio was 0.97. Elevated urinary(More)
