Expansion of extracellular matrix with fibrosis occurs in many tissues, including skin, as part of the end-organ complications in diabetes. Advanced glycosylation end-products (AGEs) have been implicated as a pathogenic factor in diabetic tissue fibrosis. Connective tissue growth factor (CTGF), also known as IGF-binding protein-related protein-2, induces(More)
Insulin-like growth factor-binding protein-3 (IGFBP-3), a major regulator of endocrine actions of IGFs, is a p53-regulated potent apoptotic factor and is significantly suppressed in a variety of cancers. Recent epidemiologic studies suggest that IGFBP-3 contributes to cancer risk protection in a variety of cancers, and a polymorphic variation of IGFBP-3(More)
Central precocious puberty (CPP) is caused by premature activation of hypothalamic gonadotropin-releasing hormone (GnRH) secretion. Kisspeptin and G-protein coupled receptor-54 system is the essential gatekeeper of the reproductive system, playing a key role in the activation of the gonadotropic axis at puberty. We aimed to determine whether serum(More)
Thirty-eight obese Korean children (21 boys, 17 girls), whose ages were between 9 and 15, were divided into either the intervention group (19 obese children: BMI>95P) or the age- and sex-matched obese control group. The intervention group performed an intensive exercise program under the supervision of educated instructors for 12 weeks (90 minutes/day, two(More)
OBJECTIVE Exercise can enhance growth and development in children, but recent investigations have revealed an intriguing paradox. Namely, the early (4-5 weeks) response to training programs in children lead to a catabolic, growth hormone (GH)-resistant state rather than the expected anabolic activation of the GH-->insulin-like growth factor-I (IGF-I) axis.(More)
Spot urinary albumin to creatinine ratio (ACR) measurement has been suggested as a surrogate to 24-hr urine collection for the assessment of microalbuminuria, and cystatin C (cysC) is known as an advantageous marker for renal function. The aim of this study was to evaluate the clinical values of spot urinary ACR and serum cysC for the assessment of diabetic(More)
The understanding of the reconstruction and calibration of electrons and photons is one of the key steps at the start-up of data-taking with ATLAS [1] at the LHC (Large Hadron Collider). The calorimeter cells are electronically calibrated before being clustered. Corrections to local position and energy measurements are applied to take into account the(More)
Insulin-like growth factor-binding protein (IGFBP)-3 has been shown to potently inhibit cell proliferation in various cell systems. However, the specific mechanisms involved in the antiproliferative action of IGFBP-3 have yet to be elucidated. In the present study, we demonstrate that IGFBP-3 induces apoptosis in an insulin-like growth factor(More)

OBJECTIVE Measurements of serum insulin-like growth factor-I (IGF-I) and IGF binding protein-3 (IGFBP-3) are utilized in the diagnostic work-up and clinical management of children with growth disorders. We designed this study to establish the reference values of serum IGF-I and IGFBP-3 levels according to age, sex and pubertal stage in Korean children and(More)
