background: proliferation and expansion of cancer stem cells as spheroids were proved in previous studies. but, capability of primary tumor-derived stem cells to keep their unique properties in vitro is still disputed. so, the goal of this study was to isolate, expand and characterize of colon cancer-derived stem cells. material and methods: in the present work, colon cancer stem cells markers ...
cancer has been always in a great attention in the field of molecular biology. by applying large-scale tools such as advanced proteomics, cancer diagnosis and treatment have been improved greatly since. cancers of esophagus, gastric, and colon accounted for major health problem globally. biomarker panel could bring out the accuracy for cancer evaluation tests as it can suggest a group of can...
Colonic lipoma is a benign neoplasm that can lead to colonic obstruction but concomitant intussusception is rare in adults. In this case, colocolic intussusception due to a lipoma in the descending colon had occurred. By laparatomy, we diagnosed the problem , but reduction was impossible . So resection of the colon with mass was done and anastomosed. After surgery and 3 years follow up the pati...
A 68 year old female housewife working occasionally in her own garden, sustained abdominal pain, discomfort and sometimes passing gaseous. Her complaints started 25 years ago. She has been seen by many physicians in her hometown Kermanshah and Karand and having medical treatments almost with no effects. The pain continued on and off until became worse. She came to Tehran and had an abdominal X-...
Soybean isoflavone genistein has multiple anticancer properties and its pro-apoptotic and anti-proliferative effects have been studied in different cancer cells. However, the mechanisms of action of genistein and its molecular targets on human colon cells have not been fully elucidated. Therefore, caspase-3 and p38 mitogen-activated protein kinase (p38 MAPK) as the main therapeutic targets...
Introduction: Ulcerative colitis is a chronic inflammation of the large intestine (colon). In patients with ulcerative colitis, ulcers and inflammation of the inner lining of the colon lead to symptoms such as abdominal pain, diarrhea, and rectal bleeding. Previous studies have shown that Matricaria recutita L. have a series of physiological effects for example spasmolytic, carminative, anti...
Introduction: The imbalance of the microbial ecosystem causes biological changes associated with colorectal cancer and cell proliferation and their planned death, as well as the immune responses. The aim of this study was to determine the effect of probiotic bacteria on the expression of genes associated with growth, metastasis and apoptosis in cancer cells of the HT29 colon. Materials & Me...
Introduction: We report a case of a 64-year old man with a history of colon carcinoma. He underwent fine-needle aspiration by CytoFoam-core and diagnosis of metastatic colon cancer to the thyroid gland. Case presentation: In this case report, a solid thyroid nodule in the right lobe of a 64-year-old male was aspirated. The cytological smears showed a small group of atypical cells with the obvi...
dear editors: adenocarcinoma of colon and rectum is the second most common cancer of the gastrointestinal (gi) tract in children. the development of carcinoma of colon in general appears to be associated with several predisposing factors such as familial polyposis, hereditary non-polyposis syndromes, ulcerative colitis, previous ureterosigmoidostomy or radiation therapy and dietary factors (hig...
