| 生化机理 | Succinic acid is a byproduct of anaerobic fermentation in microbes. It is a dicarboxylic acid and an intermediate in Kreb′s cycle. Polymorphism in succinate dehydrogenase leads to succinate accumulation. High levels of succinate impairs 2-oxoglutarate epigenetic signalling. Succinate levels may modulate tumor progression. Succinate inhibits histone demethylation and may contribute to epigenetic changes. Succinate is crucial for interleukin-1 β (IL-1β) synthesis during inflammation and immune signalling. |
