Pleiotropic Functions of Tumor Suppressor WWOX in Normal and Cancer Cells

Area of Science:

• Molecular Biology
• Genetics
• Neuroscience

Background:

• The WW domain-containing oxidoreductase (WWOX) was initially identified as a potential tumor suppressor.
• Emerging evidence reveals WWOX's involvement in diverse cellular functions, extending beyond its initial classification.
• Understanding WWOX's structure, binding partners, and phenotypic effects is key to deciphering its biological roles.

Purpose of the Study:

• To provide an overview of research methodologies employed to study the WWOX gene.
• To emphasize recent findings on WWOX's functions in metabolic regulation and CNS development.
