Background: Azo is a synthetic dye used in batik industries. It can be toxic to the tissue when exposed via inhalation, swallowing, or direct contact. Expression of cytokeratin will change in hyperplastic and cancer of the oral mucosa. Expression of Cytokeratin 8, 18, 19 is strong in the epithelial cells that undergo excessive hyperproliferation and oral mucosal changes in le...

Circulating tumor cells (CTCs) are important targets for treatment and critical surrogate markers when evaluating cancer prognosis and therapeutic response. A sensitive methodology for detecting CTCs in gastric cancer (GC) patients is needed. In this study we demonstrate a device for enrichment and cultivation of CTCs. In total, 22 patients with GC, all candidates for surgery, were enrolled in ...

Aminoflavone (AF) is an anticancer drug in early clinical trials, and its antiproliferative activity involves the induction of DNA-protein cross-links. To identify the proteins cross-linked to nucleic acids, cesium chloride (CsCl) gradient centrifugation was used to isolate proteins tightly bound to nucleic acids in AF-treated human breast carcinoma MCF-7 cells. The identified proteins included...

Mucinous cystadenocarcinoma is an extremely rare variant of primary breast tumor which is histologically similar to mucinous cystadenocarcinoma of the ovary and pancreas. Herein we report a case of a 63 years old woman diagnosed with diverse histological types of non-synchronous rare primary breast tumors, a medullary carcinoma of the right breast and a mucinous cystadenocarcinoma of the left b...

Glycogen rich clear cell carcinoma of the breast is a rare neoplasm with different morphological characteristics to ordinary breast carcinomas. However, it has some common features with clear cell carcinomas of other organs. This report describes a case of clear cell carcinoma of the breast with a solid papillary pattern centrally localised in the left breast of a 45 year old woman. Antibodies ...

Differentially expressed genes in human esophageal carcinoma/normal tissue pairs were identified by means of a modified differential display technique to overcome the limitations of the conventional technique. Out of the eight cDNAs isolated, three were novel. The other five clones consisted of cDNA encoding cytokeratin 13, complement 7, KIAA1160, expression sequence tag (EST)-Hs110855 and EST-...

BACKGROUND Malignant transformation of mature cystic teratoma is a rare complication. While any of the constituent tissues of a teratoma has the potential to undergo malignant transformation, squamous cell carcinoma is the most commonly associated malignancy. Renal carcinoid tumors are rare and frequently associated with horseshoe kidney and renal teratoma. Renal teratoma rarely presents togeth...

Rhino- and enteroviruses encode two proteinases, 2A and 3C, which are responsible for the processing of the viral polyprotein and for cleavage of several cellular proteins. To identify further targets of the 2A proteinase of human rhinovirus serotype 2 (HRV2), an in vitro cleavage assay followed by two-dimensional electrophoresis was employed. Cytokeratin 8, a member of the intermediate filamen...

Matrix metalloproteinases (MMPs) are group of enzymes thought to play an important role in trophoblastic and tumor invasion. The aim of our study was to investigate the trophoblastic expression of MMPs and p53 in normal trophoblast and hydatidiform moles (HM). Paraffin sections of 45 specimens, including 14 complete hydatidiform moles (CM), 15 partial hydatidiform moles (PM), 8 atypical partial...

OBJECTIVES Carcinoma of unknown primary origin (CUP) is heterogeneous group of cancers. Role of gastrointestinal (GI) endoscopy in this entity is under investigated. Aim of this study was to evaluate yield of Colonoscopy and Esophagogastroduodenoscopy (EGD) in localizing primary tumor in patients with CUP. METHODOLOGY Patients with histopathologically proven CUP who underwent colonoscopy / EG...
