Three lines of investigation have suggested that interactions between Survivin and the chromosomal passenger proteins INCENP and Aurora-B kinase may be important for mitotic progression. First, interference with the function of Survivin/BIR1, INCENP, or Aurora-B kinase leads to similar defects in mitosis and cytokinesis [1-7] (see [8] for review). Second, INCENP and Aurora-B exist in a complex ...

Metastasis constantly occurs in the majority of cases of primary breast cancer at late stage or following surgical treatment. Survivin, a member of the inhibitor of apoptosis protein family, has long been recognized as a promising anticancer target, but its antitumor effects remain largely unexplored. In order to elucidate the role of survivin in breast cancer metastasis, short interfering RNA ...

Survivin, which is a member of the inhibitor of apoptosis protein family, was found originally in immature cells and cancer cells but not in non-neoplastic adult tissues. The subsequent identification of four other alternative splice variants that possess distinct functions and localizations suggested the diverse roles of survivin isoforms. An unspecified isoform of survivin was found recently ...

PURPOSE Survivin is a member of the inhibitor-of-apoptosis gene family and is known to be overexpressed in a number of tumor types. The aim of this study was to evaluate the prognostic value of survivin protein expression in tumor tissue extracts in a group of well-characterized soft-tissue sarcoma (STS) patients. EXPERIMENTAL DESIGN In this investigation, malignant tissue samples from 63 STS...

Background: Expression of survivin, a member of the inhibitor of apoptosis protein family, is commonly detected in cancers but not in normal differentiated tissues. Survivin is usually localized in the cytoplasm of cancer cells, but nuclear localization has also been described, and we recently reported that survivin is a nuclear–cytoplasmic shuttling protein. Patients and methods: Fifty-three t...

Integrins are cell surface heterodimeric transmembrane receptors that, in addition to mediating cell adhesion to extracellular matrix proteins modulate cell survival. This mechanism may be exploited in cancer where evasion from apoptosis invariably contributes to cellular transformation. The molecular mechanisms responsible for matrix-induced survival signals begin to be elucidated. Here we rep...

Canine histiocytic sarcoma (CHS) is an aggressive malignant neoplasm that originates from histiocytic lineage cells, including dendritic cells and macrophages, and is characterized by progressive local infiltration and a very high metastatic potential. Survivin is as an apoptotic inhibitory factor that has major functions in cell proliferation, including inhibition of apoptosis and regulation o...

Conway et al recently reported that alternatively spliced forms of mouse survivin exhibit different antiapoptotic properties.1 This was inferred from inhibition of recombinant caspase-3 catalytic activity using a standard chromogenic assay in the presence of increasing concentrations of mammalian-expressed murine survivin isoforms of 140, 121, and 40 amino acids, respectively.1 If confirmed, th...

Survivin is a member of the inhibitor-of-apoptosis proteins (IAPs) family; its overexpression has been widely demonstrated to occur in various types of cancer. Overexpression of survivin also correlates with tumor progression and induces anticancer drug resistance. Interestingly, recent studies reveal that survivin exhibits multiple pro-mitotic and anti-apoptotic functions; the differential fun...
