It has been known that O-linked beta-N-acetylglucosamine (O-GlcNAc) modification of proteins plays an important role in transcription, translation, nuclear transport and signal transduction. The increased flux of glucose through the hexosamine biosynthetic pathway (HBP) and increased O-GlcNAc modification of protein have been suggested as one of the causes(More)
MicroRNAs have been shown to play an important role in insulin signaling but their biological function in insulin resistance induced by saturated fatty acids (SFA) remains largely unknown. Here, we report that SFA palmitate and high fat diet (HFD) significantly increase expression of miR-29a in myocytes. miR-29a targets IRS-1 3'UTR directly and represses(More)
OBJECTIVE To examine the changes from a combined exercise intervention after radical prostatectomy (RP) in elderly patients with prostate cancer, because randomized controlled trials addressing exercise intervention after RP have been lacking. METHODS From May 2009 to May 2010, all patients who underwent laparoscopic RP were assessed for eligibility. A(More)
BACKGROUND Mitochondrial dysfunction induces insulin resistance in myocytes via a reduction of insulin receptor substrate-1 (IRS-1) expression. However, the effect of mitochondrial dysfunction on insulin sensitivity is not understood well in hepatocytes. Although research has implicated the translational repression of target genes by endogenous non-coding(More)
OBJECTIVES To analyze the characteristics and the prognostic significance of chromophobe renal cell carcinomas (chRCC). METHODS Data about 2981 patients with non-metastatic renal cell carcinomas (RCC) at the time of surgery were retrospectively collected from 26 institutions between 1998 and 2008. All patients had undergone partial or radical(More)
OBJECTIVE • To assess the feasibility and oncologic efficacy of laparoscopic radical nephrectomy (LRN) compared with open radical nephrectomy (ORN) in patients with large renal cell carcinomas (RCCs) > 7 cm in size. PATIENTS AND METHODS • We analysed the data from 255 patients who underwent radical nephrectomies at 26 institutions in Korea between January(More)
BACKGROUND/AIMS There are controversies on the efficacy and safety of endoscopic submucosal dissection (ESD) for un-differentiated early gastric cancer (EGC) despite the expansion of ESD indications. The aim of this study was to evaluate the long term outcome of ESD compared to that of surgical treatment in patients with undifferentiated EGC. METHODS A(More)
BACKGROUND/AIMS Although triple combination therapy containing a proton pump inhibitor (PPI) and two antibiotics is considered as a standard regimen for the first-line anti-Helicobacter pylori treatment, the recent trend of eradication rates following this therapy has been declined in the last few years. The purpose of this study was to investigate the(More)
Recently, we found that C1qTNF-related protein 5 (CTRP5) is involved in glucose and lipid metabolism. However, the transcriptional regulation of CTRP5 is largely unknown. Here we demonstrate the mechanism by which the CTRP5 gene is transcriptionally activated in the liver. CTRP5 is activated by HNF4alpha via the region -206/-167 of the human CTRP5 promoter.(More)
