BACKGROUND The aim of this study was to investigate the correlation between Hector Battifora mesothelial-1 (HBME-1) expression and the clinical pathological characteristics and prognosis of osteosarcoma (OS). MATERIAL AND METHODS HBME-1 expression was assessed using immunohistochemistry in OS tissues (n=152), osteochondroma tissues (n=91), and normal bone tissues (n=74). We carried out a follow...

The cytologic diagnosis of papillary thyroid carcinoma is straightforward in most instances. However, there are some mimics including goitrous nodules and Hurthle cell neoplasms. Many studies have shown the combination of HBME-1 and CK19 expression to be useful in reaching a correct histologic diagnosis on tissue sections. We aim to assess the value of these markers in the setting of cell block...

OBJECTIVE Due several overlapping histomorphological features and pitfalls in thyroid pathology, there is need to establish a panel of immunomarkers that would aid in proper diagnosis. This study was carried out to investigate the ability of HBME-1, CK19, and S100 in differentiating between hyperplastic, benign and malignant thyroid lesions. MATERIALS AND METHODS Immunohistochemical analysis ...

BACKGROUND HBME-1 has been recognized as a useful marker for diagnosing thyroid carcinoma. In this study, we investigated whether it has a diagnostic value for discriminating follicular carcinoma from adenoma. MATERIALS AND METHODS We investigated HBME-1 expression in 138 follicular carcinomas, 155 follicular adenomas, 98 adenomatous nodules and 37 papillary carcinomas, using anti-HBME-1 mono...

We investigated expression of the protein human bone marrow endothelial cell marker-1 (HBME-1) in differentiated thyroid carcinoma tissues, and analyzed its correlation with ultrasonic manifestation of thyroid. The immunohistochemistry (IHC) staining method was used to measure the expression of HBME-1 in patient with nodular goiter (control group), papillary differentiated thyroid carcinoma (pa...

Understanding the regulation of endothelial cell (EC) gene expression has important implications for angiogenesis, tumor growth, and metastasis. The transcription factor runt-related gene 2 (RUNX2)/core binding factoralpha-1/acute myeloid leukemia 3/polyoma enhancer-binding protein 2alphaA/osteoblast-specific transcription factor 2 regulates osteoblast differentiation, increases lymphomagenesis...

Nearly 85% of the men who will die of prostate cancer (PCa) have skeletal metastases present. The ability of PCa cells to interact with the microenvironment determines the success of the tumor cell to form metastatic lesions. The ability to bind to human bone marrow endothelial (HBME) cells and undergo transendothelial cell migration are key steps in allowing the PCa cell to extravasate from th...

HBME-l is an antimesothelial monoclonal antibody that recognizes an unknown antigen on microvilli of mesothelial cells. The antibody is only relatively specific for mesothelium and is used in the differential diagnosis of mesothelioma and adenocarcinoma within the context of an appropriate immuno-histochemical panel. HBME-l has also been reported to strongly and uniformly stain papillary and fo...

OBJECTIVES To evaluate the expression and significance of CK19, TPO, and HBME-1 in the differential diagnosis of papillary thyroid carcinoma (PTC) and nonmalignant nodules. METHODS Tissue samples were obtained from 257 patients with PTC and 149 patients with nonmalignant thyroid specimens, and immunohistochemical staining for CK-19, TPO, and HBME-1 was performed. RESULTS The expression of C...

Pleural effusions occur in many benign and malignant conditions. The differentiation of mesothelial hyperplasia, malignant epithelial mesothelioma and metastatic adenocarcinoma in cytologic specimens is often difficult. Because many immunohistochemical studies had suggested that HBME-1 has a high sensibility but a low specificity for mesothelial differentiation, the authors investigate its util...
