Role of NF-kappaB in the anti-inflammatory effects of tocotrienols.

The NF-kappaB family of transcription factors regulates genes that are critical for inflammation and immunity. In most cells, NF-kappaB function is induced upon activation of cells by various stimuli. However, constitutive NF-kappaB activity is an equally important aspect of NF-kappaB function that is particularly relevant to chronic inflammation and cancer. Here, we provide a brief overview of NF-kappaB biology and discuss the role of NF-kappaB in mediating the anti-inflammatory effects of tocotrienols The NF-kappaB family of transcription factors is a central player in the regulation of inflammation and immune responses. Consequently, NF-kappaB dysregulation has been implicated in diverse human pathologies ranging from autoimmune diseases to cancers. Additionally, there is considerable interest in the contribution of NF-kappaB-mediated chronic inflammation in aging. Because NF-kappaB-dependent gene regulation is important in virtually all mammalian cell types, it is critical to keep in mind some basic features of its functions when considering interventional therapeutics.
