Cancer of the esophagus is the seventh leading cause of cancer death worldwide. Esophageal carcinoma cell lines are useful models to study the biological and genetic alterations in these tumors. An important prerequisite of cell line research is the authenticity of the used cell lines because the mistaken identity of a cell line may lead to invalid conclusions. Estimates indicate that up to 36%...
We examined 170 formalin-fixed paraffin-embedded samples from esophageal squamous cell carcinoma patients. All subjects live in Mazandaran province, a region with high incidence rate of esophageal cancer and have become known as the “Asian Esophageal Cancer Belt”. Samples were tested for HPV-DNA by MY09/11 and Gp5+/6+ general primers using nested PCR. Of the 170 ESCC samples, 86 (50.6%) were ma...
Background: The MET receptor is a critical member of cancer-associated RTKs and plays an important role in different biological activities, including differentiation, migration, and cell proliferation. Methods: In this study, novel MET inhibitors were introduced and applied on esophageal squamous carcinoma cell line KYSE-30, and the level of proliferation and migration, as well as the activated...
BACKGROUND Chemokine receptors have been shown to play an important role in the development and metastatic spread of various malignancies. In this study, the gene expression profile of some key chemokine receptors involved in metastasis has been investigated in esophageal and breast cancer cell lines. METHODS In a descriptive study, gene expression profile of CCR1, CCR6, CCR7, CCR9, CXCR1, an...
abstract background: esophageal cancer is one of the major malignancies, with various epidemiological aspects in recent years in developing countries, including increased prevalence and variations of pathologic patterns. this may be due to increasing rates of barrett’s esophagus, gastroesophageal reflux, smoking and obesity. this study was performed from 1991 to 2005 in order to evaluate variou...
esophageal squamous cell carcinoma is a rather common cancer in northern iran. incidence of adenocarcinoma of esophagus has an increasing trend in iran. co-existence of both cancers in one patient is very rare. we report a middle age woman from northern iran with a typical presentation of esophageal cancer, who was found to have a dual esophageal cancer. the disease was found in the advanced st...
objective(s): development of molecules that specifically recognize cancer cells is one of the major areas in cancer research. human epidermal growth factor receptor 2 (her2) is specifically expressed on the surface of breast cancer cells. her2 is associated with an aggressive phenotype and poor prognosis. in this study we aimed to isolate rna aptamers that specifically bind to her2 overexpressi...
PURPOSE To establish effective antitumor immunotherapy for esophageal cancer, we tried to identify an useful target antigen of esophageal cancer. EXPERIMENTAL DESIGN We did cDNA microarray analysis to find a novel candidate antigen, proliferation potential-related protein (PP-RP). We examined cytotoxicity against tumor cells in vitro and in vivo of CTLs specific to PP-RP established from esop...
background little is known about the possible influence of demographic and histological risk factors on the survival of patients with esophageal and gastric cancer. objectives based on the available registry and follow-up information, this study compares 1-5 year survival rate of gastric and esophageal cancer. patients and methods through a concurrent (prospective) cohort study, all 366 patient...
objective: nucleostemin (ns) is a recently identified gene that is expressed mainly in the nucleoli of neuronal, embryonic and mesenchymal stem cells which plays a role in their self renewal. over expression of this gene has been reported in several cancer cell lines tumoral tissues including gastric, hepatic and prostate cancer. in this study, we investigated the effects of suppression of this...
