Quercetin induces mitochondrial biogenesis in experimental traumatic brain injury via the PGC-1α signaling pathway.

Quercetin, a dietary flavonoid used as a food supplement, has been found to have protective effect against mitochondria damage after traumatic brain injury (TBI) in mice. However, the mechanisms underlying these effects are still not well understood. The aim of the present study was to investigate the effect of quercetin on the potential mechanism mediating these effects in the weight-drop model of TBI in male mice that were treated with quercetin or vehicle via intraperitoneal injection administration 30 min after TBI. Brain samples were collected 24 h later for analysis. Quercetin treatment upregulated the expression of PGC-1α and restored the level of cytochrome c, malondialdehyde (MDA) and superoxide dismutase (SOD). These results demonstrate that quercetin improves mitochondrial function in mice by improving the level of PGC-1α following TBI.
