BACKGROUND TNF-related apoptosis-inducing ligand (TRAIL) is an immune effector molecule that functions as a selective anti-tumor agent. However, tumor cells, especially metastatic tumor cells often exhibit a TRAIL-resistant phenotype, which is currently a major impediment in TRAIL therapy. The aim of this study is to investigate the synergistic effect of TNFα and IFN-γ in sensitizing metastatic...

slug (snai2), a regulator of epithelial-to-mesenchymal transition (emt), is a zinc finger transcription factor involved in neurulation. intriguingly, snai2 gene expression has been linked to the aggressiveness of neuroblastoma, melanoma and lung, colon, ovarian and breast carcinoma. of note, many metastatic cancers recapitulate emt to enhance cell motility and invasion. moreover, metastasis is ...

RON is a receptor tyrosine kinase belonging to the MET proto-oncogene family. The purposes of this study are to determine the expression and activation of RON in a panel of human colon carcinoma cell lines. Western blotting showed that RON is barely detectable in normal and SV-40-transformed colon epithelial cells, but highly expressed and constitutively activated in several colon carcinoma cel...

A 67-year-old woman who was presented to the gynecologist with a two-month history of heavy vaginal bleeding, after an excisional biopsy of vulvar mass, was diagnosed with the right colon adenocarcinoma metachronous metastasis to the vulva. Pathological examination preliminarily revealed by primary adenosquamous carcinoma of vulva. The original submitting pathologist and gynecologist were conta...

doi:10.1067/mge.2001.112747 including oral and isolated lymphomas involving the central nervous system have been reported in association with CD. Treatment of celiac disease with a gluten-free diet is thought to reduce the chance of CD-associated malignancies.3 Colon malignancies are generally not considered to be associated with CD. However, the results of one study suggest an association betw...

Short-chain fatty acids, metabolites produced by colonic microbiota from fermentation of dietary fiber, act as anti-inflammatory agents in the intestinal tract to suppress proinflammatory diseases. GPR109A is the receptor for short-chain fatty acids. The functions of GPR109A have been the subject of extensive studies; however, the molecular mechanisms underlying GPR109A expression is largely un...

Peroxisomes and the activities of their enzymes have been reported to be significantly reduced in various types of tumors including the colon carcinoma. Therefore, the present study was designed to investigate the gene expression of several peroxisomal proteins in human colon carcinoma and additionally those of the peroxisome proliferator activated receptor alpha (PPARalpha) and PEX5, a recepto...

Viral therapy of cancer (viral oncolysis) is dependent on selective destruction of the tumor tissue compared with healthy tissues. Several factors, including receptor expression, extracellular components, and intracellular mechanisms, may influence viral oncolysis. In the present work, we studied the potential oncolytic activity of herpes simplex virus type 1 (HSV-1), using an organ culture sys...

aim : this study aims to investigate some clinical and pathologic factors associated with the prognosis of patients with colon and rectum cancers separately. background : colorectal cancer is the most common cancer of the digestive system and also the fourth cause of cancer-related deaths around the world. different studies indicate that survival of patients with colorectal cancer has improved ...
