The molecular basis of programmed cell death (PCD) of neurons during early metamorphic development of the central nervous system (CNS) in Drosophila melanogaster are largely unknown, in part owing to the lack of appropriate model systems. Here, we provide evidence showing that a group of neurons (vCrz) that express neuropeptide Corazonin (Crz) gene in the(More)
MOTIVATION The power of a microarray experiment derives from the identification of genes differentially regulated across biological conditions. To date, differential regulation is most often taken to mean differential expression, and a number of useful methods for identifying differentially expressed (DE) genes or gene sets are available. However, such(More)
Periostin is a matricellular protein that interacts with various integrin molecules on the cell surface. Although periostin is expressed in inflamed colonic mucosa, its role in the regulation of intestinal inflammation remains unclear. We investigated the role of periostin in intestinal inflammation using Postn-deficient (Postn-/-) mice. Intestinal(More)
Although the corazonin gene (Crz) has been molecularly characterized, little is known concerning the function of this neuropeptide in Drosophila melanogaster. To gain insight into Crz function in Drosophila, we have investigated the developmental regulation of Crz expression and the morphology of corazonergic neurons. From late embryo to larva, Crz(More)
BACKGROUND We evaluated the effects of two dipeptidyl peptidase-4 (DPP-4) inhibitors, sitagliptin and vildagliptin, on metabolic parameters in patients with type 2 diabetes mellitus. METHODS A total of 170 type 2 diabetes patients treated with sitagliptin or vildagliptin for more than 24 weeks were selected. The patients were separated into two groups,(More)
Stearoyl-coenzyme A desaturase 1-deficient (SCD1(-/-)) mice have impaired MUFA synthesis. When maintained on a very low-fat (VLF) diet, SCD1(-/-) mice developed severe hypercholesterolemia, characterized by an increase in apolipoprotein B (apoB)-containing lipoproteins and the appearance of lipoprotein X. The rate of LDL clearance was decreased in VLF(More)
BACKGROUND This study compared the glycemic effectiveness of three metformin-based dual therapies according to baseline hemoglobin A1c (HbA1c) to evaluate the appropriateness of the guideline enforced by the National Health Insurance Corporation of Korea for initial medication of type 2 diabetes (T2D). METHODS This prospective observational study was(More)
Treatment of lung cancer in patients with idiopathic pulmonary fibrosis (IPF) is difficult because the mortality rate after surgery or chemotherapy is high for these patients. Spontaneous regression of cancer is rare, especially in lung cancer. A 62-year-old man, previously diagnosed with IPF, presented with stage IIIC (T2N3M0) non-small cell lung cancer.(More)
In the age of personalized medicine stratifying tumors into molecularly defined subtypes associated with distinctive clinical behaviors and predictable responses to therapies holds tremendous value. Towards this end, we developed a custom microfluidics-based bladder cancer gene expression panel for characterization of archival clinical samples. In silico(More)
BACKGROUND/AIMS The aim of this study was to evaluate the prevalence of colorectal neoplasia in subjects with fundic gland polyps (FGPs) and the relationship between FGPs and colorectal neoplasia in Korea. METHODS We analyzed 128 consecutive patients with FPGs who underwent colonoscopy between January 2009 and December 2013. For each case, age- (±5 years)(More)
