OBJECTIVE To evaluate the prognosis after esophagectomy for squamous cell carcinoma of the thoracic esophagus and its prognostic factors. METHODS Six hundred five patients with primary squamous cell carcinoma of the thoracic esophagus who underwent curative esophagectomy between June 1997 and June 1998 were collected from 3 medical centers. Among them, 26(More)
We investigated the effects of troglitazone on human cervical cancer SiHa cells and its mechanisms of action. SiHa cells were incubated with different concentrations of troglitazone (100, 200, or 400 μg/mL) for 24, 48, and 72 hours. Cell viability was measured by 3-(4,5-dimethylthiazol-2-yl) 2,5-diphenyltetrazolium bromide (MTT) assay; cell cycle and(More)
Dishevelled-2 (Dvl2) was associated with tumor cell proliferation and migration. We aimed to examine the mechanism of Dvl2 in esophageal squamous cell carcinoma (ESCC). Dvl2 was overexpressed in human ESCC tissues and cell lines ECA109 and TE1 cells. CCK-8 and colony formation assay was performed to evaluate the proliferation in ECA109 cells transfected(More)
Many long non coding RNAs have been identified as key modulators in cancer development. A lncRNA, DBCCR1-003, derived from the locus of tumor suppressor gene DBCCR1 (deleted in bladder cancer chromosome region 1), has unknown function. In the present study, we explored function and molecular mechanism of DBCCR1-003 in bladder cancer (BC) development. We(More)
miR-186 has been reported to be implicated in tumorigenesis and chemoresistance in a few cancer types. However, its role in regulating chemoresistance has not been investigated in non-small cell lung cancer (NSCLC). To examine the effects of miR-186 on chemosensitivity in NSCLC, an miR-186 mimic and inhibitor were transfected, followed by CellTiter-Glo®(More)
Accumulating evidence has pointed to a role of the CpG island hypermethylation in the regulation of cancer-related genes in tumor progression. However, the biological impacts in cancer pathogenesis associated with down-regulation of such gene targets remains elusive. Here we focused on a potential target of hypermethylation, DBCCR1 (deleted in bladder(More)
Sepia ink oligopeptide (SIO), as a tripeptide extracted from Sepia ink, could be used as an inducer of apoptosis in human prostate cancer cells. We designed a cyclo-mimetic peptide of SIO by introducing a disulfide bond to stabilize the native peptide into beta turn structure, and produced a peptide with higher cell permeability and stability. Through(More)
PCBP2 (Poly(C)-binding protein 2) is a member of PCBP family, which has many functions including mRNA stabilization, translational silence and translational enhancement performed by their poly(C)-binding ability. The abnormal expression of PCBP2 was correlated with various carcinomas. However, the significance and mechanism of PCBP2 in esophageal squamous(More)
