Syndecan-2 is a transmembrane heparan sulfate proteoglycan whose function at the cell surface is unclear. In this study, we examined the function of syndecan-2 in colon cancer cell lines. In several colon cancer cell lines, syndecan-2 was highly expressed compared with normal cell lines. In contrast, syndecan-1 and -4 were decreased. Cell biological studies using the extracellular domain of rec...
Colorectal cancer is the third most common malignancy in the United States. Improved detection sensitivity of early colorectal neoplasms would have important clinical applications. Herein, we report on using phage display to generate peptide libraries that detect colon carcinoma tissues. To accomplish this, we employed positive selection of a peptide-bearing phage library on poorly differentiat...
Distant metastasis of a colon carcinoma in situ has not yet been reported. We experienced a case of a sigmoid colon carcinoma in situ with common hepatic lymph node metastasis. After the first operation, we diagnosed dual intramucosal adenocarcinomas of the sigmoid colon without any regional lymph node metastasis. After the second operation, a metastatic adenocarcinoma was found in the common h...
Duodenal lesions are being reported in cases with familial polyposis of the colon. A case is described presenting with duodenal obstruction and pancreatitis complicating a peri-ampullary carcinoma in a patient with familial polyposis (adenomatosis of the colon and rectum). Upper gastrointestinal lesions notably in the duodenum include duodenal polyps and carcinoma and peri-ampullary malignancy....
Colon cancer is one of the leading causes morbidity and mortality throughout world. Some most common presenting signs are a change in bowel habits, alteration fecal contour or consistency, blood stool, fatigue, weight loss. However, it may present insidiously. This case an 81-year-old female with Clostridium septicum bacteremia as primary sign metastatic colon cancer. In further literature revi...
AIM Tumours of the right and left colon are suggested to be different entities with different prognosis. The aim was to explore differences related to the location of a colonic tumour. PATIENTS AND METHODS A single-centre retrospective analysis of all patients treated for colon cancer during 1999-2008 (n=1558) was carried out. Assessed data included demography, pathology and survival by cance...
Adenosquamous carcinoma of the colon consisting of both glandular and squamous histopathologic features is a rare colorectal neoplasm. Metastasis commonly occurs in right and transverse colon. A 71-year-old Caucasian man presented with a four-month history of intermittent rectal bleeding. Pathologic analysis of biopsy specimen revealed an adenosquamous carcinoma of sigmoid colon. Sigmoid resect...
Background: 4-Aryl-4H-chromenes are novel anticancer agents which induce apoptosis in cancer cells. These compounds were found to induce apoptosis by targeting the tubulin/microtubule system in cell proliferation process. The aim of this study was to report cyototoxic and apoptosis inducing activities of a new series of synthesized 4-aryl-4H-chromenes compounds. Methods: The in vitro cytotoxic...
The connective tissue stroma of malignant tumors is a newly formed tissue that supports the growth and progression of neoplastic cells. Proteoglycans are intrinsic components of this complex structure and molecular changes in this class of macromolecules can significantly affect behavioral properties of transformed cells. We report that human colon carcinoma contained increased levels of a chon...
