The present study describes the preliminary evaluation of the cytotoxicity from Gleditsiae Semen extracts. G. Semen was extracted with methanol, ethanol, and acetone, and then cytotoxic effect of these extracts was measured by the MTT reduction assay and phasecontrast microscopy on the HT-29 human colon carcinoma cells. Among these extracts, methanol extract showed the highest cytotoxic activit...

Tumor infiltrating lymphocytes (TILs) were evaluated in many cancers like ovarian tumors, endometrial colon cancer and melanoma. Now there is increasing trend evaluating TILs breast cancer. gives the patients immune response to tumor. 100 cases of Modified radical mastectomy specimen chosen from surgical pathology records. The representative formalin fixed paraffin embedded tissue samples colle...

By ALEX BERENSON Published: February 15, 2006 Doctors are excited about the prospect of Avastin, a drug already widely used for colon cancer, as a crucial new treatment for breast and lung cancer, too. But doctors are cringing at the price the maker, Genentech, plans to charge for it: about $100,000 a year. That price, about double the current level as a colon cancer treatment, would raise Avas...

The current study was assigned to evaluate the total phenol, total flavonoid content (TPC, TFC) and antioxidant properties of extracts from the aerial parts of Scrophularia frigida (S. frigida). Extracts were also tested by preliminary phytochemical screening as well as cytotoxic activity against Artemia salina, MCF-7 (human breast carcinoma) and SW-480 (colon carcinoma) and L-929 (normal) cell...

BACKGROUND Fascin is an actin-bundling protein that is absent from most normal epithelia yet is upregulated in multiple forms of human carcinoma, where its expression correlates clinically with a poor prognosis. How fascin-1 transcription is activated in carcinoma cells is largely unknown, although the hypothesis of regulation by beta-catenin signaling has received attention. The question is im...

adenocarcinomas. Adenosquamous carcinomas with consisting of both glandular and squamous histologic components are a rare malignancy of the colon and rectum. This tumor type was originally described by Herheimer in 1907. Subsequent reports of adenosquamous carcinomas of the rectum and/or colon are limited as the estimated incidence of adenosquamous carcinomas of the colon and rectum is approxim...

Development of normal colon epithelial cells proceeds through a systematic differentiation of cells that emerge from stem cells within the base of colon crypts. Genetic mutations in the adenomatous polyposis coli (APC) gene are thought to cause colon adenoma and carcinoma formation by enhancing colonocyte proliferation and impairing differentiation. We currently have a limited understanding of ...

As the prevalence of gastric carcinoma decreases in Japan, the prevalence of colon cancer has been increasing. Examination of the screening practices for colon cancer in the United States can offer insight into practices that may be useful in Japan. This paper will review the epidemiology and risk factors for colon cancer, the genetics of colon cancer, prevention issues, screening modalities, a...
