Esophageal squamous cell carcinoma and esophageal adenocarcinoma are cancers of high mortality. EAC develops through Barrett's esophagus (BE) and columnar dysplasia, preceded by gastro-esophageal reflux disease. The risk of esophageal squamous cell carcinoma is increased by smoking and alcohol consumption. New treatment options for esophageal cancer are desperately needed. Toll-like receptors (...

Background & Aims: Esophageal Cancer is the sixth fatal cancer in the world. Squamous and adenocarcinoma account for 95% of esophageal cancer. The expression of EGFR has a role in the pathophysiology of epidermal-based malignancies such as esophageal cancer. EGFR is also an important criterion in the evaluation of disease staging and prognosis. The aim of this study was to survey the prevalence...

background: ß-carbolines, harmaline and harmine, are the major alkaloids presenting in the seeds of the peganum harmala l. these alkaloids are known as herbal active principals with potential use in pharmaceutical and medicine. objectives: to assess the growth inhibitory effect of phyto-alkaloids, harmaline and harmine, on cancer cell lines. methods: the p. harmala l.’s alkaloids were extracted...

Esophageal cancer is a serious malignancy with regards to mortality and prognosis. Current treatment options include multimodality therapy mainstays of current treatment including surgery, radiation, and chemotherapy. Cell therapy for esophageal cancer is an advancing area of research. We report a case of esophageal cancer following cord blood-derived cytokine-induced killer cell infusion and a...

We examined AIS status in digestive tract cancers and found that all eight esophageal cancer cell lines (100%) showed AIS/TA-AIS gene overexpression, whereas 1 of 12 (8%) gastric cancer and 0 of 14 (0%) colon cancer cell lines showed AIS/TA-AIS gene expression. We then confirmed that the AIS gene, not the TA-AIS gene, was dominantly expressed in esophageal cancers by reverse transcriptionPCR. A...

BACKGROUND Esophageal cancer is recognized as one of the most refractory pernicious diseases. In addition, it is an aggressive malignancy with a propensity for local progression and distant dissemination. Because of the poor long-term prognosis for patients with esophageal cancer, increasing attention has focused on the integration of targeted agents into current therapeutics. Nevertheless, the...

The Toll-like receptor 9 (TLR9) plays a crucial role in both innate and adaptive immune responses against infection and danger signals. Stimulation of TLR9 has been linked to invasion in various cancer cells in vitro. The present study evaluated the expression of TLR9 in human esophageal cancer (EC) cells and normal and malignant esophageal squamous epithelium, and examined the association betw...

Arachidonic acid (AA) is the major precursor of several classes of signal molecules and the alteration of its metabolism is involved in human carcinogenesis. For instance, 5-lipoxygenase (5-LOX) converts AA to hydroxyeicosatetraenoic acids or leukotrienes (LTs), which are able to enhance proliferation, increase survival and suppress the apoptosis of human cells. To determine the potential use o...

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...
