Gprotein-coupled receptor kinases (GRKs) are known to be involved in the development of cardiac hypertrophy. Their exact role and subcellular distribution during cardiac hypertrophy and failure remain to be elucidated. We examined expression and subcellular distribution of GRK2 and GRK5 in the left ventricle of female spontaneously hypertensive heart(More)
PURPOSE As the proportion of early gastric cancer (EGC) has recently been increased, minimally invasive treatment is currently accepted as main therapy for EGC. Accurate preoperative staging is very important in determining treatment options. To know the accuracy of endoscopic ultrasonography (EUS), we compared the depth of invasion of the tumor with(More)
α-amy gene amplified from barley genome was cloned into MCS of pGAP9K to generate pGAP9K-α-amy which was then transformed into Pichia pastoris GS115 by electroporation. Transformants with multi-copies and high expression for the foreign gene were selected on G418 containing plate and expression analysis. The fermentation was carried out in a 50 l bioreactor(More)
Focal adhesion kinase (FAK) and focal adhesion kinase-related nonkinase (FRNK) are likely involved in mechanical signaling during hypertension. We investigated expression, subcellular distribution, and phosphorylation of FAK, as well as FRNK in left ventricles of spontaneously hypertensive heart failure rats. Compared with normotensive controls, FAK and(More)
Beta-catenin is not only an adhering junction protein, but also the central player of the canonical Wnt signalling pathway. In order to investigate the roles of β-catenin in the mechanism of myocardial hypertrophy, we determined the expression and distribution of β-catenin in the cardiomyocytes of spontaneously hypertensive heart failure (SHHF) rats and(More)
PURPOSE Gastric cancer surgery is a common operation in East Asia, such as Korea and Japan, and there has been a significant increase in the need for this procedure due to the aging population. As a result, surgery for the treatment of gastric cancer for elderly patients is expected to increase. This study examined the effect of old age on gastric cancer(More)
The objective of the present study is to determine the role of prostaglandin E2 (PGE2) and downstream EP receptors in the development of human papillary thyroid carcinoma (PTC). A total of 90 thyroid specimens excised from patients undergoing total or subtotal thyroidectomy in the Department of General Surgery, the Fifth Affiliated Hospital of Sun Yat-sen(More)
Hemangioma is a tumor that causes vascular endothelial cell hyperplasia, which commonly occur in newborns. Angiogenesis inhibitor targets the processes of angiogenesis, including the proliferation of vascular endothelial cells. A DNA sequence named Scl was designed, recombined into Pichia Pastoris, expressed by fermenting the engineered strain in a(More)
