Akt-dependent FOXO3a cytoplasmic translocation is an important tumorigenic mechanism for escaping from apoptosis in cancer cells. In the present study, we examined whether non-phosphorylatable FOXO3a can inhibit cell growth of various follicular thyroid carcinoma (FTC) cell lines. Adenovirus carrying the FOXO3a-triple mutant (TM) sequence including point(More)
A significant proportion of patients with papillary thyroid cancer (PTC) present with extrathyroidal extension (ETE) and lymph node metastasis (LNM). However, the molecular mechanism of tumor invasiveness in PTC remains to be elucidated. The aim of this study is to understand the role of Hedgehog (Hh) signaling in tumor aggressiveness in patients with PTC.(More)
Metabolic reprogramming has been regarded as an essential component of malignant transformation. However, the clinical significance of metabolic heterogeneity remains poorly characterized. The aim of this study was to characterize metabolic heterogeneity in thyroid cancers via the analysis of the expression of mitochondrial ribosomal proteins (MRPs) and(More)
BACKGROUND/AIMS Although magnetic resonance imaging (MRI) is a good visual modality for the evaluation of pituitary lesions, it has limited value in the diagnosis of mixed nodules and some cystic lesions. We evaluated the usefulness of (18)F-fluorodeoxyglucose positron emission tomography (FDG PET) for patients with pituitary lesions. METHODS (18)F-FDG(More)
OBJECTIVE We aimed to evaluate whether 4-week of dietary treatment with rice containing resistant starch reduces blood glucose and oxidative stress as well as improves endothelial function. METHODS Patients with impaired fasting glucose (IFG), impaired glucose tolerance (IGT) or newly diagnosed type 2 diabetes (n = 90) were randomly assigned to either a(More)
Progression to overt hypothyroidism and the associated adverse effects on lipid metabolism and the cardiovascular system are major concerns for patients diagnosed with subclinical hypothyroidism (SCH). No consensus regarding the clinical parameters associated with prognosis for this mild thyroid dysfunction has yet been established, although elevation of(More)
Excessive iodine intake is known to induce hypothyroidism in people who have underlying thyroid disorders. However, few studies have been performed on subjects with normal thyroid function without a history of autoimmune thyroid disease. We hypothesized that high iodine intake may cause a subtle change in thyroid function even in subjects with normal(More)
This study was designed to evaluate the effect of Korean red ginseng (KRG) supplementation on glucose control in subjects with impaired fasting glucose (IFG), impaired glucose tolerance (IGT), or newly diagnosed type 2 diabetes mellitus (T2DM). The study was a 12-week randomized, double-blinded, placebo-controlled (5 g of KRG [n=21] or placebo [n=20] in(More)
Recent functional genomic studies revealed that the oncogenic activity of focally amplified lncRNA on chromosome 1 (FAL1, ENSG00000228126) contributes to tumor growth by p21 repression in human cancers. However, the expression of FAL1 was not investigated in papillary thyroid cancer (PTC). We aimed to determine if FAL1 was up-regulated in PTC compared to(More)
OBJECTIVE To investigate clinical characteristics of patients with Graves' orbitopathy (GO) who showed discrepancies between levels of thyroid-stimulating immunoglobulin (TSI) and thyrotropin-binding inhibitory immunoglobulin (TBII). DESIGN Comparative case series. PATIENTS A total of 317 patients with GO in whom Mc4-TSI and M22-TRAb (third-generation(More)
