Introduction: Occurrence of follicular thyroid carcinoma (FTC) is limited almost within thyroid gland, but distant metastasis is discovered uncommonly as first presentation. We experienced a rare case about recurrent bone metastasis of FTC with unknown primary site.Case report: A 58-year-old woman complained about back pain for 3 years. A 5 cm sized mass in right 8th posterior rib was discovered and performed resection. The result of pathology was bone m...

Background: Endothelial progenitor cells (EPCs) play an important role in neovascularization and endothelial regeneration, and the number and function of circulating EPCs is decreased in patients with diabetic retinopathy and type 1 diabetic nephropathy. However, the number and function of EPCs in patients with type 2 diabetes nephropathy is unknown.Methods: Participants were divided into three groups: 1) type 2 diabetes with overt nephropathy (DN group,...

Runx2 and Osterix(Osx) have been known as the master transcription factors for bone formation. However, genes that act downstream of both Runx2 and Osx have not been fully studied. To investigate downstream target genes of Runx2 and Osx, DNA microarray was conducted in calvaria of WT, Runx2ΔC/+, Osx+/−, and Runx2ΔC/+; Osx+/− double heterozygous mice designated WT, Runx2het, Osxhet, and Doub...

Introduction: ACTH-producing pheochromocytoma has been rarely reported, ranging from 3 to 25% of the ectopic ACTH syndrome. Moreover, a few cases of Cushing’s syndrome (CS) accompanied with opportunistic infections have been reported. We experienced a case of pheochromocytoma with ectopic CS, complicated by invasive aspergillosis.Case report: A 35-year-old woman visited our hospital because of headache for 2 months. She presented with typical cushin...

Background and aims: Recently, a metabolic syndrome severity score (MS score) using a dataset of the Korea National Health and Nutrition Examination Surveys has been developed. We aimed to determine whether the newly developed score is a significant predictor of cardiovascular (CV) events among the Korean population.Methods: From the Korean National Health Insurance System, 2,541,364 (aged 40–59 years) subjects with no history of CV events (ischemi...

Objective: Menopausal transition contributes to sarcopenia, but the effects of hormone replacement therapy (HRT) on sarcopenia in postmenopausal women have not been determined. This study assessed the effect of HRT on sarcopenia in postmenopausal women.Methods: The present study included 4,254 postmenopausal women who participated in the Korea National Health and Nutritional Examination Surveys in 2008–2011. Appendicular skeletal muscle mass divide...

Accepted dogma once stated that G protein-coupled receptors (GPCRs) function as monomers, however, over the last decade in vitro experiments have shown GPCRs to function as dimers and higher order oligomers. We have recently reported the first in vivo evidence for the physiological importance of Class A GPCR homodimerisation using the LHCGR as a model receptor. Transgenic co-expression of binding deficient LHCGR (LHCGR-LH) and signalling deficient ...

G protein-coupled receptors (GPCRs) are one of the largest families of the mammalian genome, mediating the effects of approximately 40% of prescribed drugs. Until recently, accepted dogma stated that GPCRs exist as monomers, however, it is becoming evident that GPCRs can form higher order dimer/oligomer complexes which provide important mechanisms for the diversification of receptor function. The LHCGR is a class A family GPCR, primarily coupling to the Gαs pat...

3beta-hydroxysteroid dehydrogenase (3beta-HSD) expression is essential for the synthesis of all classes of steroid hormones, converting delta5-3beta-hydroxysteroids into hormonally active delta4-3-ketosteroids in NAD+-dependent reactions. A variety of 3beta-HSD isoforms have been described in primate, rodent and other mammals, often exhibiting distinct kinetic properties, preferential subcellular localization, as well as alternative substrate s...

Objective: Despite beneficial effect of FGF-21 on metabolic disease, there were concerns about adverse effect on bone metabolism, supported by animal studies. However, a recent human study showed the positive association between FGF-21 and bone mineral density (BMD) in health premenopausal women. This study was undertaken to examine the association between FGF-21 and BMD in healthy postmenopausal Korean women who are susceptible to osteoporosis.<p class="a...
