Abstract
Background: Disease entities such as diabetes, neurodegeneration and cardiovascular disorders affect a significant portion of the world's population. Objective: Given that cellular survival and longevity in multiple disorders are tied to oxidative stress, apoptotic cell injury and immune system deregulation, the development of robust therapeutic strategies rests heavily upon the ability to balance each of these parameters. Methods: Here we discuss two exciting signaling pathways, namely Wnt and mammalian forkhead transcription factors predominantly of the O class superfamily, which can share integrated cytoprotective pathways during oxidative stress but may also adversely influence cellular survival and promote cancer cell proliferation. Conclusion: Future investigations must elucidate the cellular determinants that govern the ability of Wnt and forkhead proteins to promote cellular longevity and possible disease remission but also allow for detrimental biological consequences and clinical compromise.
