NDRG (N-Myc downstream-regulated gene)-2 is a member of the NDRG family. Although it has been suggested that NDRG2 is involved in cellular differentiation and tumor suppression, its intracellular signal and regulatory mechanism are not well known. Here, we show the differential expression of NDRG2 in human colon carcinoma cell lines and tissues by reverse(More)
NDRG (N-Myc downstream-regulated gene)-2 is a member of the NDRG family. Although it has been suggested that NDRG2 is involved in cellular differentiation and tumor suppression, its in-tracellular signal and regulatory mechanism are not well known. Here, we show the differential expression of NDRG2 in human colon carcinoma cell lines and tissues by reverse(More)
A 50-year-old male patient presented with a right scrotal mass that had been growing rapidly for more than one year. A heterogeneous enhancing right scrotal mass (12×9 cm) with para-aortic and peri-caval lymphadenopathies was found on abdominal computed tomography (CT). Right orchiectomy was performed and the gross finding had shown intact testis with a(More)
BACKGROUND/AIMS Tumor angiogenesis, a major requirement for tumor growth and metastasis, is regulated by pro- and anti-angiogenic factors. Hepatocellular carcinoma (HCC) has become a common malignant tumor worldwide. It is characterized by a high vascularity. METHODS We studied the immunohistochemical expression of angiostatin, vascular endothelial cell(More)
BACKGROUND There is subjective disagreement regarding nuclear clearing in papillary thyroid carcinoma. In this study, using digital instruments, we were able to quantify many ambiguous pathologic features and use numeric data to express our findings. METHODS We examined 30 papillary thyroid carcinomas. For each case, we selected representative cancer(More)
The diagnostic role of (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET)/computed tomography (CT) for gallbladder small cell carcinoma has not been reported. A knowledge of the imaging characteristic features of this malignancy can be useful. Here we report a rare case of a patient who had various diagnostic imaging modalities,(More)
BACKGROUND Thymosin β4 is a multi-functional hormone-like polypeptide, being involved in cell migration, angiogenesis, and tumor metastasis. This study was undertaken to clarify the clinicopathologic implications of thymosin β4 expression in human colorectal cancers (CRCs). METHODS We investigated tissue sections from 143 patients with CRC by(More)
Primary clear cell tumors of the breast are uncommon and often present a diagnostic challenge. We describe an extremely rare case of glycogen-rich clear cell malignant myoepithelioma in a 43-year-old woman. Histologically, this tumor is composed of clear cells with abundant cytoplasmic glycogen particles. Immunohistochemically, these tumor cells show(More)
