OBJECTIVE The sensitivity of cytologic examination of pleural effusions is variable and not predictive of prognosis. Survivin is an inhibitor of apoptosis that may be a novel diagnostic/prognostic marker of cancers. This study aimed to determine the diagnostic and prognostic value of measuring survivin mRNA levels in pleural effusions. METHODS Eighty-eight consecutive pleural effusion samples...

Survivin, an inhibitor of apoptosis (IAP) protein detected in many tumors but not in most normal differentiated tissues, has been widely recognized as an attractive target for cancer therapy. We previously showed that survivin expression is associated with cell proliferation. Although liposome-mediated transfection of survivin-specific siRNA decreases survivin expression and cell proliferation,...

MG-63 human osteosarcoma cells were transfected with short hairpin RNA (shRNA) against livin and survivin using monomethoxypolyethylene glycol‑chitosan (mPEG‑CS) nanoparticles (NPs) as carriers, with the aim of evaluating the effect on cell proliferation and apoptosis. mPEG‑CS NPs sized ~100 nm were prepared by ionic crosslinking. mPEG‑CS‑livin shRNA, mPEG‑CS‑survivin shRNA and mPEG‑CS‑(livin s...

OBJECTIVE To determine matrix metalloproteinase-2 and survivin expressions in endometrial cancers, their relation to clinical and histologic parameters and to investigate any difference in the expression of these markers between endometrioid and nonendometrioid cancers. METHODS Ninety-five patients with endometrial cancer, were included. Matrix metalloproteinase-2 and survivin expressions wer...

Survivin is a unique inhibitor of apoptosis, which is frequently present within degenerated human nucleus pulposus (NP) cells. Survivin has been extensively investigated using proliferation and apoptosis assays in tumor cells; however, studies conducted on survivin in degenerative NP cells remain limited to date. The aim of the present study was to investigate survivin expression and its effect...

Internal tandem duplication mutations in the Flt3 tyrosine kinase gene (ITD-Flt3) and overexpression of Survivin are frequently found in patients with acute myeloid leukemia (AML). We investigated whether Survivin mediates the enhanced survival of primary hematopoietic progenitor cells (HPCs) resulting from ITD-Flt3 signaling. Ectopic ITD-Flt3 mutants increased Survivin expression in Ba/F3 cell...

BACKGROUND Survivin is a mammalian protein that carries a motif typical of the inhibitor of apoptosis (IAP)proteins, first identified in baculoviruses. Although baculoviral IAP proteins regulate cell death, the yeast Survivin homolog Bir1 is involved in cell division. To determine the function of Survivin in mammals, we analyzed the pattern of localization of Survivin protein during the cell cy...

Survivin is an apoptotic and mitotic regulator that is overexpressed in melanoma and a poor prognostic marker in patients with metastatic disease. We recently showed that Survivin enhances melanoma cell motility through Akt-dependent upregulation of α5 integrin. However, the functional role of Survivin in melanoma metastasis is not clearly understood. We found that overexpression of Survivin in...

Survivin is a member of the family of proteins, which inhibit apoptosis (inhibitor of apoptosis proteins - IAP). Expression of survivin was found in colorectal cancer, neuroblastoma, bladder cancer, non-small cell lung cancer, and breast cancer. There is some recent data indicating the correlation of poor prognosis and worse response to chemotherapy in patients with oesophageal squamous cell ca...

Although erythroid cells and megakaryocytes arise from a common progenitor, their terminal maturation follows very different paths; erythroid cells undergo cell-cycle exit and enucleation, whereas megakaryocytes continue to progress through the cell cycle but skip late stages of mitosis to become polyploid cells. In our efforts to identify genes that participate in this process, we discovered t...
