Abstract EN

2,3,5,4′-Tetrahydroxystilbene-2-O-β-D-glucoside (TSG), an important monomer extracted from Polygonum multiflorum, can prevent a number of inflammation associated chronic diseases.

However, the mechanism involved in TSG inducing anti-inflammatory role remains unclear.

As an inducible antioxidant enzyme, Heme oxygenase-1 (HO-1), is crucial for protecting the mammalian cells against adverse stimuli.

Here, we found that the TSG treatment strongly induces the expression of HO-1 in an NRF2-depended manner.

Meanwhile, TSG increased the mitochondrial mass through upregulation of the mitochondrial biogenesis activators (PGC-1α, NRF1, and TFAM) as well as the mitochondrial complex IV.

Furthermore, TSG attenuated Lipopolysaccharide (LPS) mediated RAW264.7 cells activation and secretion of proinflammatory cytokines, including interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α).

Zinc Protoporphyrin (ZnPP), a selective inhibitor of HO-1 activity, was able to attenuate TSG mediated mitochondrial biogenesis and anti-inflammatory process.

Finally, we observed that LPS induced obvious mtDNA depletion and ATP deficiency, which indicated a severe damage of mitochondria.

TSG restored the LPS induced mitochondrial dysfunction via activation of the mitochondrial biogenesis.

ZnPP treatment markedly reversed the inhibitory effects of TSG on mitochondrial damage and oxidative stress in LPS stimulated macrophages.

Taken together, these findings suggest that TSG enhances mitochondrial biogenesis and function mainly via activation the HO-1.

TSG can be developed as a potential drug for treatment of inflammatory diseases.
