Genetically engineered stem cells may be advantageous for gene therapy against various human cancers due to their inherent tumor-tropic properties. In this study, we employed human neural stem cells (HB1.F3; hNSCs) transduced with genes expressing Escherichia coli cytosine deaminase (HB1.F3.CD) and human interferon-beta (HB1.F3.CD.IFN-β) as a treatment strategy for human lymph node metastatic colorectal cancer. CD can convert the prodrug 5-fluorocytosine (5-FC) to its act...

Objective: The exogenous somatostatin inhibits insulin secretion in pancreatic cell and could lead to hyperglycemia. But, Glucagon-like peptide-1 (GLP-1) has insulinotropic actions despite stimulating somatostatin secretion in δ cell. So, we examined whether there is a time difference of insulin and somatostatin secretion after GLP-1 stimulation or secretion rate difference of insulin and somatostatin depending on GLP-1 concentration and glucose concentration ins...

Aims: Previous reports have demonstrated that the adipocyte-derived peptide adiponectin is closely associated with insulin resistance due to its insulin-sensitizing and anti-inflammatory properties in peripheral tissues; however the autocrine effects of adiponectin remain elusive. This study investigated regulatory effects of adiponectin on glucose transport and insulin signalling in insulin-sensitive or insulin-resistant 3T3-L1 adipocytes.Methods: 3T3-L...

LHX3 is a LIM homeodomain transcription factor necessary for proper development of the pituitary and central nervous system. Patients with mutations in coding regions of the LHX3 gene have complex syndromes including combined pituitary hormone deficiency and nervous system defects resulting in symptoms such as dwarfism, thyroid insufficiency, infertility, and developmental delay. Although previous studies from our group and others have identified promoter and intronic elements...

Patients with type 2 diabetes have an increased risk of premature coronary heart disease (CHD). One of the underlying reasons for this increased risk is atherogenic dyslipidemia. Current management strategies focus on the initial use of statin or fibrate therapy (the latter approach indicated in patients with pronounced hypertriglyceridemia).American Diabetes Association recognizes serum triglycerides as a surrogate for atherogenic triglyceride-rich lipo...

Backgrounds: As the average lifespan in human increases, osteoporosis and osteoporosis-related fractures have been major health care problems. Despite recent advances in medical treatment, few studies have assessed the recognition of osteoporosis by general adults. This study examined the recognition of osteoporsosis and analysed the relating factors.Methods: We made one to one questions in a rural area called chunjunlee in chunchon city. The questionnai...

Purpose: To evaluate the association between ultrasonography (US) feature of thyroid gland and thyroid function in pediatric and adolescent populations with autoimmune diffuse thyroid diseases (AITD).Methods: From 2000 to 2020, we reviewed thyroid ultrasound (US) images and thyroid function statuses in 133 children and adolescent AITD patients. Our review of the images focused on decreased echogenicity and heterogeneity, which were classified into four g...

Growth hormone (GH) excess is extremely rare in children. It can be associated with endocrine syndromes including MEN1, Carney complex and Mc Cune Albright syndrome. We describe two cases of GH excess and their management. Patient A (15yr M) presented with fibrous dysplasia affecting his cranium and a large café-au-lait spot covering his right scapula. His height was 193cm (2.6 SDS) and BMI 29.6kg/m2(2.3SDS). His IGF1 was 84.1nmol/L (22.5 – 65.9) and GH did not suppr...

Background: Sarcopenia is associated with mortality in patients with chronic kidney disease (CKD). However, the extent to which sarcopenia contributes to this risk, either independently or in conjunction with metabolic abnormalities and frailty, remains unclear. Therefore, this study aimed to explore the associations among sarcopenia, frailty, central obesity, metabolic abnormalities, cardiovascular risks, and mortality.Methods: This study used data from...

Calbindin-D9k (CaBP-9k), one of the major calcium-binding and calcium-buffering proteins, is important in the physiological functioning of organs. The neuroanatomical localization of CaBP-9k in the rodent brain has not been reported; thus, this study investigated the neuroanatomical distribution of CaBP-9k and the regulation of CaBP-9k expression on steroid hormones in the immature rat brain. To confirm the influence of steroid hormones on CaBP-9k expression, immatu...
