Cell-surface markers for colon adenoma and adenocarcinoma

Cell-surface markers for colon adenoma and adenocarcinoma

Early detection of colorectal cancer (CRC) is crucial for effective treatment. Among CRC screening techniques, optical colonoscopy is widely considered the gold standard. However, it is a costly and invasive procedure with a low rate of compliance. Our long-term goal is to develop molecular imaging agents for the non-invasive detection of CRC by molecular imaging-based colonoscopy using CT, MRI...

Possible Involvement of a Specific Cell Surface Receptor for Calprotectin-Induced Apoptosis in Colon Adenocarcinoma and Carcinam Cell Lines (SW742 and HT29/219)

Calprotectin, a calcium-bound protein complex, is abundant in the cytosol of neutrophils. It has been reported that this protein has an apoptotic activity in tumor cells. Since calprotectin increases in colorectal cancer, this study was conducted to investigate, for the first time, the cytotoxicity/apoptotic effect of calprotectin on HT29/219 and SW742 colon carcinoma and adenocarcinoma cell li...

Apoptosis in adenoma and early adenocarcinoma of the colon.

Twenty-six specimens of tubular adenoma and 7 specimens of adenocarcinoma in adenoma of the colon were examined to evaluate apoptosis between adenoma and early adenocarcinoma. Cell proliferation and cell death seemed to be balanced in adenoma with mild and moderate atypia, but unbalanced in adenoma with severe atypia and cancer. Apoptosis was considered to be suppressed at cancer in some cases....

Cancer Stem Cell Markers CD44, CD133 in Primary Gastric Adenocarcinoma

Cancer stem cells (CSCs) are unique subpopulations that have the capacity to drive malignant progression with renewal abilities. Recently the role of some of CSCs in gastric adenocarcinoma has been studied. This study was performed in order to evaluate CD44 and CD133 expressions by immunohistochemistry in 95 primary gastric adenocarcinoma and their relation to clinical and pathological paramete...
