WWOX

WWOX is a proapoptotic protein and a tumor suppressor protein. It is found in all eukaryotes and involved in the regulation of a broad range of cellular functions such as protein degradation, transcription, and RNA splicing. WWOX functions synergistically with TP53/p53 to control genotoxic stress-induced cell death. WWOX takes part in tumor necrosis factor (TNF)-mediated cell death.

 Loss of WWOX expression is associated with pancreatobiliary cancers. Reduced expression levels of WWOX protein is associated with the pathogenesis of basal-like differentiation in breast cancer. Loss of WWOX expression is associated with extrahepatic cholangiocarcinoma.

In addition, protein levels of WWOX, its Tyr33-phosphorylated form, and WOX2 are significantly down-regulated in the neurons of Alzheimer's hippocampi.
