MiRNAs play important roles in tumorigenesis. This study focused on exploring the effects and regulation mechanism of miRNA-137 on the biological behaviors of gastric cancer. Total RNA was extracted from tissues of 100 patients with gastric cancer and from four gastric cancer cell lines. Expression of miR-137 was detected by real-time PCR from 100 patients. The effects of miR-137 overexpression...

background: prostate cancer is one of the leading causes of cancer deaths among men. new gene expressed in prostate (ngep), is a prostate-specific gene expressed only in normal prostate and prostate cancer tissue. because of its selective expression in prostate cancer cell surface, ngep is a potential immunotherapeutic target. to target the ngep in prostate cancer, it is essential to investigat...

EBV-associated gastric carcinoma is a distinct subset of gastric carcinoma infected with EBV, which shows latency I type expression of EBV latent genes (EBNA1, EBER, BARF0, and LMP2A). To clarify the role of EBV in this type of gastric carcinoma, the cell biological characteristics (growth, apoptosis, and migration) were evaluated in gastric carcinoma cell lines (MKN-1, TMK1, MKN-74 and MKN-7) ...

Cancer stem cells (CSCs) possess the ability of self-renewal and tumor initiation. Targeting key signaling pathways that are active in CSC self-renewal is one approach to cancer therapy. Abnormal activation of the Wnt/β-catenin pathway has been described in a wide variety of human cancers and in CSCs; however, the role of this pathway in gastric CSCs has not been reported. In our study, we inve...

Recent evidence shows that v-ets erythroblastosis virus E26 oncogene homolog 1 (Ets1) is implicated in tumor development and progression. However, the clinical potentials and underlying mechanisms of Ets1 in gastric cancer progression and metastasis remain largely unknown. In this study, Ets1 immunostaining was identified in 56 of 84 (66.7%) gastric cancer tissues, which was correlated with tum...

The aim of the present study was to assess the anticancer effect of several naftopidil analogues on human malignant mesothelioma cell lines NCI-H28, NCI-H2052, NCI-H2452, and MSTO-211H, human lung cancer cell lines A549, SBC-3, and Lu-65, human hepatoma cell lines HepG2 and HuH-7, human gastric cancer cell lines MKN-28 and MKN-45, and human bladder cancer cell lines 253J, 5637, KK-47, TCCSUP, T...

We have previously demonstrated the ability of I-Trp to disrupt the protein-protein interaction of β-tubulin with chaperonin-containing TCP-1β (CCT-β). This caused more severe apoptosis in multidrug-resistant MES-SA/Dx5, compared to MES-SA, due to its higher CCT-β overexpression. In this study, we screened a panel of cancer cell lines, finding CCT-β overexpression in the triple-negative breast ...

shiga toxins (stxs) are bacterial virulence factors produced by shigella dysenteriae serotype 1 and escherichia coli strains. stxs are critical factors for the development of diseases such as severe bloody diarrhea and hemolytic uremic syndrome. additionally, stxs trigger the secretion of pro- inflammatory cytokines and chemokines, particularly in monocytes or macrophages. the inflammatory cyto...
