WWOX-Related Neurodevelopmental Disorders: Models and Future Perspectives

Area of Science:

• Genetics and Molecular Biology
• Neuroscience
• Developmental Biology

Background:

• The WW domain-containing oxidoreductase (WWOX) gene, initially identified at the FRA16D fragile site, exhibits diverse biological functions beyond its putative tumor suppressor role.
• WWOX is increasingly recognized for its involvement in various neurological conditions, particularly developmental and epileptic encephalopathies (DEEs).

Purpose of the Study:

• To review and analyze the diverse model systems employed to investigate the function and neuropathological roles of WWOX.
• To compare and contrast the utility and limitations of rodent and human models in WWOX research.
• To identify future research directions and promising avenues for studying WWOX in neuropathies.

Main Methods:

• Literature review of studies utilizing various model systems (e.g., cell cultures, animal models) to investigate WWOX.
• Comparative analysis of findings across different model systems, focusing on similarities and differences between rodent and human models.
• Synthesis of current knowledge and identification of research gaps.

Main Results:

• WWOX plays a significant role in neuronal development and function, with mutations linked to DEEs.
• Rodent models offer valuable insights into WWOX function but have limitations in fully recapitulating human neuropathologies.
• Human-derived models, while complex, provide more direct relevance to human disease.

Conclusions:

• WWOX is a critical gene implicated in neurological disorders, especially DEEs.
• A range of model systems are essential for comprehensively understanding WWOX's complex roles in neuropathies.
• Further research utilizing both established and novel models is needed to elucidate WWOX function and develop therapeutic strategies.
