Hydroxytyrosol promotes autophagy by regulating SIRT1 against advanced oxidation protein product-induced NADPH oxidase and inflammatory response

Sun T, Chen Q, Zhu SY, Wu Q, Liao CR, Wang Z, Wu XH, Wu HT, Chen JT · International Journal of Molecular Medicine

Restores autophagy through SIRT1 and blunts NADPH-oxidase-driven inflammation — the autophagy arm of the olive-polyphenol case, which is what distinguishes it from a plain antioxidant story.

Population

Primary chondrocytes from newborn rats exposed to advanced oxidation protein products, framed as a rheumatoid arthritis model

Intervention

Hydroxytyrosol at 75 μM for 30 minutes before the stressor

Comparator

Untreated

Limitations

Rat cell culture; the stressor is a chemical oxidation product rather than a joint condition, and the framing is rheumatoid. Funded by China's National Natural Science Foundation.
