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)
The insulin-like growth factor binding protein (IGFBP) family is a critical component of the insulin-like growth factor (IGF) system which regulate the biological actions of the IGFs and may also be capable of IGF-independent actions. To date, seven distinct IGFBPs have been described. Among these IGFBPs, IGFBPs-1-6 bind IGFs with high affinity, while only(More)
Metabolic syndrome is associated with visceral obesity, insulin resistance and an increased risk of cardiovascular diseases. Visceral fat tissue primarily consists of adipocytes that secrete cytokines leading to a state of systemic inflammation in obese conditions. One of the IGF-independent functions of IGFBP-3 is its role as an anti-inflammatory molecule.(More)
which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Longitudinal standards for height and height velocity are essential to monitor for appropriate linear growth. We aimed to construct standards in Korean children and adolescents through the population-based longitudinal(More)
Kisspeptin/G-protein couple receptor-54 (GPR54) system plays a key role in the activation of the gonadotropic axis at puberty. Central precocious puberty (CPP) is caused by the premature activation of hypothalamic gonadotropin-releasing hormone secretion. This study was aimed to identify KISS1 gene variations and to investigate the associations between(More)
Exposure to endocrine disrupting chemicals (EDCs), particularly during developmental periods, gives rise to a variety of adverse health outcomes. Bisphenol A (BPA) is a well-known EDC commonly found in plastic products including food and water containers, baby bottles, and metal can linings. This study investigates infant exposure to BPA and the effect of(More)
Growth hormone (GH) treatment has been increasingly widely used for children with GH deficiencies as the survival rate of pediatric patients with malignancies has increased. Both GH and insulin-like growth factor-I have mitogenic and antiapoptotic activity, prompting concern that GH treatment may be associated with tumor development. In this review, the(More)
Insulin-like growth factor binding protein (IGFBP)-3 has roles in modulating the effect of IGFs by binding to IGFs and inhibiting cell proliferation in an IGF-independent manner. Although recent studies have been reported that IGFBP-3 has also roles in metabolic regulation, their exact roles in adipose tissue are poorly understood. In this review, we(More)
which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Longitudinal standards for height and height velocity in Korean children and adolescents: the Kangwha cohort study. The official name of this population based cohort study is the 'Kangwha Study. ' Therefore, the title is(More)
When evaluating the underlying causes of tall stature, it is important to differentiate pathologic tall stature from familial tall stature. Various pathologic conditions leading to adult tall stature include excess growth hormone secretion, Marfan syndrome, androgen or estrogen deficiency, testicular feminization, and sex chromosome anomaly, such as(More)
