Aims: We investigated the interrelationship between HbA1c, fructosamine, glycoalbumin (GA), 1,5-anhydroglucitol (1,5-AG) with glycemic variability data from continuous glucose monitoring system (CGMS).Methods: Seventy diabetic patients (mean age of 54 years including seven type 1 diabetes mellitus subjects) were enrolled, and all wore a CGMS for 72 hours. For the parameters of glucose excursion, mean glucose, standard deviation (SD) of glucose, the area ...

A Randomized controlled trial of the effect of internet based mentoring program for type 1 diabetes patients with inadequate glycemic control

Suh S. , Park S. , Cho Y. , Joung J. , Jin S. , Kim S. , Kim H. , Bae J. , Kim S. , Chung J. , Min Y. , Lee M. , Lee M. , Kim K. , Kim J.

Introduction: Widespread availability of internet makes it an attractive communication tool among patients and providers. However, the clinical benefit of telemedical support on diabetes care remains inconclusive. This study is to determine whether an internet based mentoring program can improve glycemic control in type 1 diabetes (T1DM) patients with inadequate glycemic control.Methods: Patients with T1DM on intensive insulin therapy and with HbA1c &#x2...

Bisphenol A and phthalate stimulated the growth of human prostate cancer cells and altered downstream target genes of ras signaling pathway

Kim K. , Lee H. , Choi K.

Prostate cancer have been most cause of cancer death to men in recent, but there are not effective treatments for this cancer. In growth of prostate cancer, steroid hormones such as androgen play a role in their growth and survival. However, endocrine disrupting chemicals (EDCs) intend to bind the hormone receptor and induce the abnormal hormone response. EDCs have potency to activate estrogen receptor (ER) and androgen receptor (AR) mediated signaling pathways, and they cause...

Regulation of adiponectin by free fatty acids in lean and obese subjects

Kim K. , Nam S. , Ahn C. , Yu J. , Kim K. , Cha B. , Lee H. , Richelsen B.

Objective: To evaluate the effects of free fatty acids (FFAs) on the regulation of plasma and adipose tissue mRNA adiponectin expression in lean and obese subjects.Methods: Seven obese men (31.3±1.1 kg/m2) and eight lean men (21.3±0.4 kg/m2) were studied. Subjects received an Intralipid 20% infusion over 180-min with sodium heparin. Blood sampling and abdominal subcutaneous adipose tissue biopsy were taken before and after...

PTTG binding factor (PBF) can transform cells independently of interaction with PTTG

Stratford AL , Boelaert K , Kim DS , Franklyn JA , McCabe CJ

We have previously shown PTTG and PBF to be over-expressed in differentiated thyroid cancer and to be prognostic indicators for recurrence. Subsequently we reported PBF to be a transforming gene in vitro and tumourigenic in vivo. Since over-expression of PTTG results in the same findings, we examined whether PBF-induced tumourigenesis was an independent effect, or else a result of increased PTTG activity. Two HA-tagged mutants of PBF were generated, firstly subst...

Somatostatin Abrogates GH-Induced Hepatocyte IGF-I Transcription by Inhibiting STAT5b Phosphorylation & Nuclear Translocation

Murray RD , Kim K , Umehara Y , Melmed S

Use of somatostatin (SRIF) analogs in acromegaly indicates greater lowering of IGF-I than predicted from GH reduction. Studies using hypophysectomized rats suggest a direct SRIF action on GH-induced IGF-I, however, interpretation is complicated by effects of SRIF on other hormonal axes. In isolated rat hepatocytes we showed SRIF and octreotide to have a direct inhibitory effect, via hepatic SSTRs, on GH-induced IGF-I production. GH (500 ng/ml) caused ~4 fold induction of IGF-I...

The level of Osterix expression in osteoblasts is important to prevent IL6-induced inflammatory-prone state

Baek W. , Kim Y. , Park S. , Kwon T. , Park K. , Kim J.

Osterix (Osx) is an essential transcription factor for osteoblast differentiation and bone formation. Osx null mutants died perinatally with a complete absence of bone formation and Osx conditional knockouts in osteoblasts showed the osteopenic phenotype after birth. Even in Osx heterozygous mice with normal bone morphology, the reduced cortical thickness and osteoblast differentiation were observed by QCT and in vitro cell culture, respectively. This result exhibited t...

Prevalence of elevated glycated hemoglobin in women with polycystic ovary syndrome: according to the recently defined criteria

Chae S. , Kim J. , Choi Y. , Hwang K. , Yoon S. , Kim K.

Background: Insulin resistance is a core pathophysiology of polycystic ovary syndrome (PCOS). The screening recommendations for type 2 diabetes in PCOS patients have varied according to organizations, but the AE-PCOS Society recommended that a OGTT be performed in obese patients or in lean patients with advanced age (>40 year), with a history of gestational diabetes, or with a family history of type 2 diabetes. Recently, the American Diabetes Association (ADA) newly includ...

Most of type 2 diabetes associated loci identified in genome-wide association studies are not associated with polycystic ovary syndrome

Yoon S. , Kim J. , Choi Y. , Hwang K. , Chae S. , Kim K.

Objective: Insulin resistance is a core feature of polycystic ovary syndrome (PCOS), thus, it may be the common link between PCOS and type 2 diabetes (T2DM).Although the etiology of PCOS has not been elucidated, a number of studies have suggested that genetic factors may play important roles in its etiology and pathogenesis. If PCOS and T2DM share a common genetic background, genetic variants determining the risk of T2DM may also be associated with PCOS....

Metabolic characteristics in women with polycystic ovary syndrome by phenotypes based on various diagnostic criteria

Sung Y. , Kim D. , Baik S. , Won K. , Kim H. , Oh J. , Lee H.

The metabolic features of Polycystic ovary syndrome (PCOS) can vary based on the definition used. The aim of this study is to compare the metabolic characteristics of PCOS according to the phenotypes from various diagnostic criteria and help to establish a optimal diagnostic criteria.Subjects with PCOS defined by the NIH criteria (n=494) and the Rotterdam criteria (n=568) and regular cycling non-hirsuite control women (n=1000) were r...
