Background: WWOX (WW domain-containing oxidoreductase) gene, located on chromosome 16q 23.3-24.1 in the region recognized as the common fragile site FRA16D is considered to be a tumor suppressor gene involved in various cancers: breast, ovarian, prostate, esophageal, lung, pancreatic, gastric and hepatic. The aim of this study was to describe (i) putative protein interactions of WWOX (ii) the molecular mechanisms of tumor suppressor activity (iii) present an overview of WWOX in relation to nervous system and breast, prostate and ovarian cancers. Methods and Results: WWOX expression is up-regulated in endocrine organs indicating its importance in these tissues. In many cancers WWOX expression is down-regulated and low WWOX expression is related to poor prognosis. Conclusion: All the evidence suggest that WWOX can be considered as a new tumor suppressor gene and target for gene therapy due to the association of high WWOX expression with improved disease free survival.

    Despite the fact that tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) can selectively induce apoptosis in cancer cells, TRAIL resistance in cancer cells has challenged the use of TRAIL as a therapeutic agent. First, prostate carcinoma cell lines (DU145, LNCaP and PC3) were...

    To develop a gene therapy that would selectively kill prostate cancer cells while sparing normal cells, we have constructed lentiviral vectors that contain a therapeutic gene with a short DNA sequence in the 5′-untranslated region (UTR) that is recognized by the translation initiation...

    The use of conditionally replicating adenoviruses offers an attractive complementary treatment strategy for localized prostate cancer. We have produced a replicating adenovirus, Ad[I/PPT-E1A], where E1A gene expression is controlled by a recombinant regulatory sequence designated PPT. The PPT...

    Background: Mining novel breast cancer genes is an important task in breast cancer research. Many approaches prioritize candidate genes based on their similarity to known cancer genes, usually by integrating multiple data sources. However, different types of data often contain varying degrees of...
