Neutrophil gelatinase-associated lipocalin (NGAL), also known as lipocalin 2, is a 25-kDa lipocalin initially purified from neutrophil granules. It is thought to play a role in regulating cellular growth since its expression is highly upregulated in a variety of proliferative cells such as cancer cells. However, experimental evidence showing a clear causal(More)
CONTEXT A significant number of papillary thyroid microcarcinomas (PTMCs), despite excellent prognosis, show aggressive features such as extrathyroidal extension (EE) and lymph node metastasis (LNM) that may not always be detected preoperatively or intraoperatively. The relapse rate appears also substantial. OBJECTIVE To assess the value of(More)
Apolipoprotein(a) [apo(a)] contains the largest numbers of kringle domains identified to date. Of these, apo(a) kringle V shows significant sequence homology with plasminogen kringle 5, which is reported to be a potent angiogenesis inhibitor. To determine the effects of apo(a) kringle V on angiogenesis, it was expressed as a soluble protein (termed rhLK8)(More)
HRPT2, the gene associated with hyperparathyroidism-jaw tumor (HPT-JT) syndrome, was previously mapped to 1q24-q32. It was recently cloned, and several germline mutations were found to predispose to HPT-JT syndrome. We sequenced the complete HRPT2 coding sequence and splice-junctional regions in a Korean family with HPT-JT syndrome and identified a novel(More)
BACKGROUND Human cytomegalovirus (HCMV) major immediate early (MIE) promoter, which is involved in viral reactivation, is specifically activated by androgen in LNCaP prostate cancer cells. METHODS Androgen-dependent transcriptional activities of the HCMV MIE promoter were measured by transient transfection assay. Expression levels of genes related to(More)
BACKGROUND Anti-angiogenesis therapy has been regarded as a promising treatment of cancer based on the fact that most tumors and their metastasis are angiogenesis-dependent. Gene therapy can potentially expand the horizons of tumor angiogenesis therapy by virtue of its ability to produce high concentrations of therapeutic agents in a local area for a(More)
The formation of hepatic metastases in colorectal cancer is the main cause of patient death. Current therapies directed at hepatic metastasis of colorectal cancer have had minimal impact on outcome. Therefore, alternative treatment strategies for liver metastasis require development. The present study was performed to evaluate the application of cDNA of(More)
To evaluate the roles of 4 putative downstream molecules (ERK, p38 MAPK, JNK and AKT) of the RET signal pathway in the tumorigenesis of papillary carcinomas, the expression patterns of RET and phosphorylated forms of ERK, p38 MAPK, JNK and AKT were evaluated in 115 cases of papillary thyroid carcinomas by 3 mm-core tissue microarray based(More)
This study aimed to determine the incidence and characteristics of HER-2 gene heterogeneity in invasive breast cancer in a single institution. Included were 971 cases of primary invasive breast cancer diagnosed between 2008 and 2010. Fluorescence in situ hybridization (FISH) image files were retrospectively reviewed and HER-2 gene heterogeneity was defined(More)
Unlike simple images processed by the existing image-based search engines, flowers have wider and more irregular range of shapes and patterns. In this paper we present an automatic recognition system of flowers for smartphone users. After a user transmits a flower image to the server, the image processing and searching is performed only by the server,(More)
