BACKGROUND Survivin is an inhibitor of apoptosis protein and is involved in the occurrence and progression of human malignancies. Recently, a functional polymorphism (-31G>C, rs9904341) in the promoter of survivin has been shown to influence its expression and confer susceptibility to different types of cancer. The present study was aimed to investigate whether the polymorphism also influences ...

Gene therapy is a promising adjuvant therapeutic strategy for cancer treatment. To overcome the limitations of current gene therapy, such as poor transfection efficiency of vectors, low levels of transgene expression and lack of tumor targeting, the Survivin promoter was used to regulate the selective replication of oncolytic adenovirus in tumor cells, and the heat shock protein 70 (Hsp70) gene...

We previously reported that Sp1-dependent Cdc2 gene expression is inhibited by tetra-O-methyl nordihydroguaiaretic acid (M(4)N) and that M(4)N is likely responsible for causing growth arrest in M(4)N-treated transformed C3 cells. Here, we show that after M(4)N treatment and cell-cycle arrest, expression of the Sp1-dependent survivin gene, a member of the inhibitor of apoptosis family, is also s...

Osteosarcoma is the most frequent malignant bone tumor with a peak incidence in the second and third decades of life. Diagnosis of patients with osteosarcoma is limited to clinico-pathological parameters whereas molecular markers of tumor initiation and promotion have not yet been identified. We aimed to study the expression of the anti-apoptotic survivin gene in osteosarcoma specimens. A total...

Statins are used widely to lower serum cholesterol and the incidence of cardiovascular diseases. Growing evidence shows that statins also exhibit beneficial effects against cancers. In this study, we investigated the molecular mechanisms involved in lovastatin-induced cell death in Fadu hypopharyngeal carcinoma cells. Lovastatin caused cell cycle arrest and apoptosis in FaDu cells. Lovastatin i...

Abstract Objectives The accumulation of genetic damages in onset cancer induce activation protooncogenes or inactivation tumor suppressor genes thus cause disruption the balance between cell proliferation and programmed death. As a member apoptosis inhibitory protein family (IAP), survivin play important roles carcinogenesis process. evidence suggests that polymorphisms located promoter region ...

The aim of this study was to investigate the selective killing effect of the herpes simplex virus-thymidine kinase/ganciclovir (TK/GCV) suicide gene system controlled by the survivin promoter on hepatocellular carcinoma (HCC) cells in vitro. Recombinant plasmid vectors driven by the survivin promoter were constructed. HepG2 HCC and LO2 normal huma...
