Abstract :

Oxidative stress signifi cantly aff ects multiple cellular pathways that can lead to the onset and progression of dysfunction in the vascular system and related disorders such as those that involve immune system function. It therefore is essential to understand the basis of the cellular components that can be targeted against oxidative stress in the vascular system and associated cellular pathways. In this regard, we investigated in vascular models of oxidative stress the role of the ?O? class forkhead transcription factors that also are closely linked to the immune system. We show that forkhead is a necessary element in the control of early and late apoptotic injury programs that involve membrane phosphatidylserine externalization and nuclear DNA degradation. Furthermore, prior to the onset of apoptotic injury, forkhead leads to the activation and proliferation of infl ammatory cells as early as 3 hours following oxidative stress that occurs in conjunction with the traffi cking of the unphosphorylated and active post-translational form of forkhead transcription factors from the cytoplasm to the cell nucleus. Forkhead also controls apoptotic mitochondrial signal transduction pathways that involve the release of cytochrome c and the activation of caspase 3, 8, and 9. Interestingly, forkhead transcription factors function not only as therapeutic targets, but also as biomarkers of disease onset and progression. Here we present the exciting role of forkhead in the vascular system, but also outline the sometimes unexpected and detrimental outcomes for these transcription factors that highlight the need for future studies to develop safe and effi cacious platforms for vascular disease.
