In order to develop an effective strategy of breast cancer therapy targeting survivin and its splice variants survivin-ΔEx3 and survivin-2B, the present study constructed four expression vectors by fusing the survivin antisense gene, the survivin (T34A) gene, the survivin-ΔEx3 antisense gene, and the survivin-2B gene with the enhanced green fluorescent protein (eGFP) gene. Each of these vectors...
OBJECTIVE This study was designed to determine the level of survivin expression and its clinical significance as a prognostic factor in Stage III gastric adenocarcinoma. METHODS We performed immunohistochemical staining for survivin, p53 and Bax in formalin-fixed, paraffin-embedded blocks from 157 surgically resected Stage III gastric cancer tissues. To determine the association with clinical...
Survivin is a member of the inhibitor of apoptosis gene family that has been implicated in both apoptosis inhibition and regulation of mitosis. However, the subcellular distribution of survivin has been controversial and variously described as a microtubule-associated protein or chromosomal passenger protein. Here, we show that antibodies directed to the survivin sequence Ala(3)-Ile(19) exclusi...
The role of Survivin in the pathogenesis of leukemia was explored in order to discover the effective avenues for gene therapy. Most primary leukemia cells isolated from patients as well as three leukemia cell lines (HL-60, K562, and U937) all expressed Survivin gene. To investigate the relationship between Survivin and chemotherapeutic resistance, HL-60 cells were treated with daunorubicin (DNR...
Loss of p53 function due to human papillomavirus (HPV) infection induces resistance to apoptosis in cervical cancer cells. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), which induces apoptosis in a p53-independent manner, may provide an alternative strategy for treating cervical cancer. Survivin, an antiapoptotic protein that is highly expressed in cancer cells, regulates apo...
Gastric cancer is the second leading cause of cancer-related death worldwide. Survivin overexpressed in many human cancers as a member of the inhibitor of apoptosis protein family. We found that all samples of normal gastric tissues did not express the protein of survivin, and however, 65% human gastric cancer samples expressed survivin. Positive expression of survivin correlated with different...
Rheumatoid arthritis (RA) is a highly heterogeneous disease with respect to its joint destructivity. The reasons underlying this heterogeneity are unknown. Deficient apoptosis in rheumatoid synovial tissue has been recently demonstrated. We have therefore decided to study the synovial expression of survivin, a key member of the apoptosis inhibitor family. The levels of survivin and antibodies a...
introduction: survivin, an inhibitor of apoptosis (iap) containing one baculoviral iap repeat (bir) domain, has been reported to be able to regulate both cellular proliferation and apoptotic cell death. in the present study, we evaluated the differential expression of different variants of survivin during prenatal and postnatal development of brain in mice. material and methods a total of 27 nm...
Survivin plays separate roles during different phases of the cell cycle. In mitosis, Survivin is a key regulator of cell division, while in interphase, Survivin is able to protect cells from apoptosis. Survivin shuttles between nucleus and cytoplasm under the influence of one or more nuclear export signals (NESs). Paradoxically, our data show that Survivin poorly binds CRM1 in vitro because hyd...
BACKGROUND Survivin is highly expressed in cancer cells but shows little or no expression in normal tissues. Little is known about antibody responses to survivin in patients with head and neck cancer. METHODS Anti-survivin antibody responses in patients with head and neck cancer were investigated by enzyme-linked immunosorbent assay. Anti-p53 antibody and squamous cell carcinoma antigen were ...
