Survivin is a critical regulator of mitosis, and an inhibitor of apoptosis which is overexpressed in almost all cancers. In the current study, cell cycle profiles of normal proliferating human umbilical vein endothelial cells, prostate cancer, and lung cancer cell lines expressing varying levels of survivin and its splice variants were compared using a novel functional complementation assay. De...

objective: because of the necessity of more effective treatments for the nervous system injuries and considering the role of survivin in cellular proliferation and apoptotic cell death, we have monitored survivin gene expression changes during the course of regeneration in injured sciatic nerves and also l4-l6 segments of spinal cord. materials and methods: we used adult male nmri mice as a mo...

Background: A total of 4 additional splice variants (survivinEx3, survivin 2 , survivin-2B, and survivin3B) have been described of survivin [baculoviral IAP repeat-containing protein (BIRC-5), approved gene symbol BIRC5], which has been implicated in both inhibition of apoptosis and regulation in mitosis in many tumor types. In this study, we assessed whether the survivin splice variants modula...

BACKGROUND Survivin is a small protein inhibitor of apoptosis and a tumor associated antigen. Survivin expression in multiple myeloma is associated with poor prognosis, disease progression, and drug resistance. The CD4+ response against survivin remains uncharacterized. METHODS In order to better understand the anti-tumor immune response to survivin, and optimize vaccination strategies, we ch...

background : mdm2, e-cadherin, survivin and her2 genes are involved in the regulation of normal cell growth. however, any crucial change in their expression levels can convert a normal cell into a cancer cell. numerous studies have identified alterations of these gene expression levels in various cancers, particularly in breast cancer. thus, they may be used as diagnostic biomarkers. in this ex...

INTRODUCTION Alternative splicing distinguishes normal and pathologic cells. High levels of oncoprotein survivin recognise patients with severe rheumatoid arthritis (RA). Here, we assess clinical relevance of alternative splicing of survivin in leukocytes of peripheral blood (PBMC) and bone marrow (BM) in RA patients. METHOD Transcription of survivin wild-type (survivin-WT), survivin-2B and s...

INTRODUCTION High levels of the oncoprotein survivin may be detected in the majority of patients with early rheumatoid arthritis (RA). Survivin is a sensitive predictor of joint damage and persistent disease activity. Survivin-positive patients are often poor responders to antirheumatic and biological treatment. The aim of this study was to investigate the reproducibility of survivin status and...

PURPOSE Recently, two alternatively spliced survivin variants, survivin-ΔEx3 and survivin-2B, were identified in a single copy of the survivin gene. It has been reported that the expressions of survivin splice variants significantly correlates with the clinical results in many types of human carcinoma. We investigated the transcription levels of survivin and its splice variants in human colorec...

Abstract Substantial evidence has shown that overexpression of the inhibitor apoptosis protein (IAP) survivin in human tumors correlates significantly with treatment resistance and poor patient prognosis. Survivin serves as a radiation factor impacts DNA damage response by interacting DNA-dependent kinase (DNA-PKcs). However, complexity, molecular determinants, functional consequences this inte...
