Livin is one of the most important members of the inhibitor of apoptosis protein family. It is overexpressed in several types of tumors and may have prognostic significance. The present study investigated the biological role of Livin in the oncogenic behavior of gastric cancer cells, the expression of Livin in gastric cancer tissue and the relationship of(More)
Myeloid cell leukemia-1 (Mcl-1) is a highly expressed anti-apoptotic Bcl-2 protein in cancer. Therefore, inhibition of its expression induces apoptosis in cancer cells and enhances sensitivity to cancer treatment. The aims of this study were to evaluate whether Mcl-1 affects the oncogenic behaviors of colorectal cancer cells, and to document the(More)
AIMS AND BACKGROUND The aims of the current study were to evaluate whether recepteur d'origine nantais (RON) affects tumor cell behavior and oncogenic signaling pathways in colorectal cancer, and to examine the relationship of its expression with various clinicopathological parameters and patient survival. METHODS Immunohistochemistry, Western blot and(More)
The expression of myeloid cell leukemia-1 (Mcl‑1), a member of the anti-apoptotic Bcl-2 protein family, has been associated with tumor progression and adverse patient outcome. The aims of current study were to evaluate whether Mcl-1 affects the survival or death of gastric cancer cells, and to investigate the prognostic value of its expression in gastric(More)
BACKGROUNDS Expression of Livin, a member of the inhibitors of apoptosis protein family, is associated with tumor development and progression. The aims of this study were to evaluate whether Livin affects oncogenic biological behavior of colorectal cancer cells, and to document the relationship between its expression and various clinicopathological(More)
Early growth response-1 (Egr-1) is implicated in the regulation of cell growth, proliferation, differentiation and apoptosis. Egr-1 is considered tobe either a tumor-suppressor or tumor-promoter, depending on the cell type and environment. The aim of the present study was to evaluate the expression of Egr-1 in colorectal cancer and its correlation with(More)
AIM Livin, a member of the inhibitors of apoptosis proteins, is expressed in variable cancers, and its expression is considered a poor prognostic marker. The aims of this study were to observe the effect of Livin on the behaviors of hepatocellular carcinoma (HCC) cells and to evaluate its expression in HCC tissues and its relation to prognosis. METHODS(More)
BACKGROUND/AIMS Gastric schwannoma (GS), a rare neurogenic mesenchymal tumor, is usually benign, slow-growing, and asymptomatic. However, GS is often misdiagnosed as gastrointestinal stromal tumors (GIST) on endoscopic and radiological examinations. The purpose of this study was to evaluate EUS characteristics of GS distinguished from GIST. METHODS A(More)
The early growth response-1 (Egr-1) is crucial in many cell regulatory processes related to the progression of human cancers. Its overexpression has been demonstrated in variable human cancers and may have prognostic significance. The aims of this current study were to evaluate whether Egr-1 affects invasive and oncogenic phenotypes of human gastric cancer(More)
Variceal bleeding is the most serious complication of portal hypertension, and it accounts for approximately one fifth to one third of all deaths in liver cirrhosis patients. Currently, endoscopic treatment remains the predominant method for the prevention and treatment of variceal bleeding. Endoscopic treatments include band ligation and injection(More)
