Cell protection by polyphenols

Dr. Shawn Talbott (Ph.D., CNS, LDN, FACSM, FACN, FAIS) has gone from triathlon struggler to gut-brain guru! With a Ph.D. in Nutritional Biochemistry, he's on a mission to boost everyday human performance through the power of natural solutions and the gut-brain axis.

Have you ever wondered why Amare Global’s VitaGBX is so high in polyphenol-rich phytonutrients?

One reason is because they can help to protect delicate neurons (brain cells) from damage – and another is because they can help to improve blood flow to the brain, thus improving delivery of oxygen and nutrients for optimal brain performance.

But – did you also know that polyphenols can activate intracellular protection pathways like Nrf2 (to increase antioxidant enzyme production) AND inhibit inflammatory pathways like NF-KB (to reduce inflammatory cytokine production)?

This means that polyphenol-rich diets and supplements (like VitaGBX) have the potential to not just “protect” cells – but to help cells to actively “protect themselves” whenever they’re exposed to stress. No other multivitamin does what VitaGBX can do…

I though this recent paper (from 16 scientists in 7 countries) about NF-kB signaling by polyphenols was interesting? This research focuses on cancer, but the concept applies to any aspect of improved cellular protection – such as anti-aging effects.

Abstract

Being a transcription factor, NF-?B regulates gene expressions involving cell survival and proliferation, drug resistance, metastasis, and angiogenesis. The activation of NF-?B plays a central role in the development of inflammation and cancer. Thus, the down-regulation of NF-?B may be an exciting target in prevention and treatment of cancer. NF-?B could act as a tumor activator or tumor suppressant decided by the site of action (organ). Polyphenols are widely distributed in plant species, consumption of which have been documented to negatively regulate the NF-?B signaling pathway. They depress the phosphorylation of kinases, inhibit NF-?B translocate into the nucleus as well as interfere interactions between NF-?B and DNA. Through inhibition of NF-?B, polyphenols downregulate inflammatory cascade, induce apoptosis and decrease cell proliferation and metastasis. This review highlights the anticancer effects of polyphenols on the basis of NF-?B signaling pathway regulation.
