background and objectives: involvement of lymph nodes is an important prognostic factor in the most cancers, including colorectal cancer. in the recent years, invasion to blood and lymphatic vessels has been shown to predict involvement of lymph nodes and the number of involved nodes has been less studied issue. the aim of this study was determination of the relationship between the size of col...

medicinal plants have been investigated for possible anti-cancer effects. the aim of the present study was to examine the cytotoxic activity of several medicinal plants on different tumor cell lines. 11 selected plant species which have been used in folkloric prescriptions were collected from different sites of hamedan district of iran. the methanolic extracts of the plants were prepared and th...

Four human colon adenocarcinoma cell line variants with different metastatic potential were used to examine whether a correlation exists between actin level, state of actin polymerization and invasiveness of tumour cells. Monomeric (G), total (T) and filamentous (F) actin were determined in the cytosolic fraction of these cells. A statistically significant decrease in G actin level and increase...

Four major carcinoembryonic antigen-related glycopeptides (Mr 180,000, 160,000, 50,000, and 40,000) were detected in SW948 colon carcinoma cells and in colon adenocarcinoma tissue using a monoclonal antibody (C(4)20-32) generated by immunizing mice with SW1222 human colon carcinoma cells. Only the Mr 50,000 polypeptide was immunoprecipitated from normal colon mucosa by this antibody. Binding st...

PURPOSE The present a novel adenocarcinoma model in athymic mice. METHODS Seven athymic mice were used. Colon diversion and distal fistula were made. Adenocarcinoma cells were inoculated in the submucosa of fistula. Tumor growth was monitored daily. Scintigraphy with 99mTc-MIBI was performed to identify the tumor. RESULTS The model of distal colon cancer is feasible. Tumor detection was pos...

background gastric cancer is the second most common cause of cancer death worldwide. lentinan was shown to induce apoptosis in gastric cancer cells and could be used for the treatment of gastric cancer. objectives in this study, we analyzed anticancer effect of lentinan, a fungal β-glucan, on the gastric adenocarcinoma cell line (ags). materials and methods we used the dna ladder and tunnel app...
