Autophagy is a cellular mechanism that maintains cellular homeostasis. It declines in aging and is associated with osteoarthritis. MicroRNAs regulate autophagy, but only a few are involved in osteoarthritis. Epigenetic modifications could be a therapeutic opportunity for osteoarthritis. Polyphenols have the potential to reverse epigenetic alterations and modify autophagy in cartilage.
Autophagy is an intracellular mechanism that maintains cellular homeostasis in different tissues. This process declines in cartilage due to aging, which is correlated with osteoarthritis (OA), a multifactorial and degenerative joint disease. Several studies show that microRNAs regulate different steps of autophagy but only a few of them participate in OA. Therefore, epigenetic modifications could represent a therapeutic opportunity during the development of OA. Besides, polyphenols are bioactive components with great potential to counteract diseases, which could reverse altered epigenetic regulation and modify autophagy in cartilage. This review aims to analyze epigenetic mechanisms that are currently associated with autophagy in OA, and to evaluate whether polyphenols are used to reverse the epigenetic alterations generated by aging in the autophagy pathway.
