Survivin, a member of the inhibitor of apoptosis protein family, is widely expressed in a variety of human cancer tissues. Survivin inhibits activation of caspases, and its overexpression can lead to resistance to apoptotic stimuli. In this study, survivin protein expression was assessed by immunohistochemical staining of 195 invasive breast cancer specimens. Overall, 79.5% of the tumors were p...

The present study examined the downregulation of survivin expression by hypoxia-inducible factor-1α (HIF-1α) miRNA and its effect in the inhibition of A549 cell growth in vitro and in vivo. Survivin expression, apoptosis, proliferation and migration under normoxic and hypoxic conditions were assessed by standard methods. Cotransfection and chromatin immunoprecipitation were used to observe the ...

PURPOSE The present study examined the clinicopathological impact of survivin expression in oesophageal squamous cell carcinoma (ESCC). In addition, the biological role of anti-apoptosis parameter in ESCC was examined immunohistochemically. PATIENTS AND METHOD Subjects comprised 71 patients followed up for 5 years after surgery for ESCC and analysed immunohistochemically to examine the clinic...

OBJECTIVES Inflammatory macrophage apoptosis is critical to atherosclerotic plaque formation, but its mechanisms remain enigmatic. We hypothesized that inhibitor of apoptosis protein (IAP) survivin regulates macrophage death in atherosclerosis. METHODS AND RESULTS Western blot analysis revealed discrete survivin expression in human aorta lipid streaks but virtually none in advanced atheroscle...

Survivin is an independent prognostic factor for joint destruction in rheumatoid arthritis (RA). However, the expression and function of survivin in RA synoviocytes remain unclear. We certified the expression of survivin in RA synovial tissues and performed the experiment using RA fibroblast-like synoviocytes (RA-FLS) treated with siRNA. As a result, the expression levels of wild type (WT) surv...

Survivin, a 16.5 kDa tumor associated antigen, is the smallest member of the inhibitor of apoptosis family that is abundantly expressed during development but essentially absent in normal adult tissues. Interestingly, survivin expression is up-regulated in virtually all types of cancers studied, as well as in vascular endothelial cells during tumor associated angiogenesis. Survivin links apopto...

965 Survivin is a bifunctional protein that suppresses apoptosis and regulates cell division (1). This protein has garnered great interest as a potential drug target because its expression is among the most tumor-specific of all human gene products (2). While fetal tissues contain abundant Survivin mRNA and protein, most normal adult tissues do not. In contrast, the vast majority of tumors expr...

BACKGROUND The identification of biomarkers that predict optimal and individual choices of treatment for patients with rheumatoid arthritis gains increasing attention. The purpose of this study was to investigate if the proto-oncogene survivin might aid in treatment decisions in early rheumatoid arthritis. METHODS Serum survivin levels were measured in 302 patients who completed the Swedish p...

Survivin is a tumor marker for bladder cancer; however the role of urinary survivin levels has not been fully elucidated due to the limitations of current detection methods. Based on two survivin-specific monoclonal antibodies (McAbs) already confirmed through enzyme linked immunosorbent assays, the present study aimed to establish a microplate magnetic chemiluminescence immunoassay (CLIA) for ...

Castration-resistant prostate cancer (CRPC) remains an obstacle in the current treatment provided for prostate cancer (PCa). Survivin, an apoptosis inhibitor, has been found to be involved in the progression of PCa, and is a promising candidate target for CRPC therapy. Micro (mi)RNAs are involved in the progression of PCa through the regulation of multiple genes. One of the objectives of the pr...
