Although endocannabinoid signaling is important for certain aspects of gastrointestinal homeostasis, the role of the cannabinoid receptors (CB) in colorectal cancer has not been defined. Here we show that CB1 expression was silenced in human colorectal cancer due to methylation of the CB1 promoter. Our genetic and pharmacologic studies reveal that loss or inhibition of CB1 accelerated intestina...

objective: inhibition of apoptosis may favor the onset and progression of cancer. survivin is an inhibitor of apoptosis that has been considered as a potential marker for diagnostic and/or prognostic of bladder cancer. the survivin protein regulates both cell division and cell death and is overexpressed in the vast majority of human cancers. in this study, the expression pattern and potential p...

We reported earlier that exposure to exogenous bone morphogenetic protein 7 (BMP7) could strongly inhibit serum starvation-induced apoptosis to C4-2B cell line, a variant of the LNCaP human prostate cancer cell line with propensity for bone metastasis. Whereas serum starvation suppressed the expression of survivin, a member of the inhibitor of apoptosis protein family, its expression was sustai...

Objectives: Considerable differences are known between proximal and distal colon, these include embryological, anatomical, histological, biochemical, physiological characteristics. Above mentioned distinctions may influence development of variable clinico-morphological entities. Multifunctional antiapoptotic protein survivin participates in regulation cell cycle, apoptotic cascades, stimulates ...

BACKGROUND A total of 4 additional splice variants (survivin-DeltaEx3, survivin 2alpha, survivin-2B, and survivin-3B) have been described for 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 vari...

background: the aim of this study was to detect the prognostic significance of survivin level and the expression of total p53 in acute lymphoblastic leukemia (all) and its correlation to patients' outcome. methods: sixty two children newly diagnosed with acute lymphoblastic leukemia were treated with chemotherapy and followed up for 2 years or until death. twenty apparently healthy volunteers w...

Incomplete abolition of tumorigenicity creates potential safety concerns in clinical trials of regenerative medicine based on human pluripotent stem cells (hPSCs). Here, we demonstrate that conditionally replicating adenoviruses that specifically target cancers using multiple factors (m-CRAs), originally developed as anticancer drugs, may also be useful as novel antitumorigenic agents in hPSC-b...

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...
