Cancer-induced bone pain (CIBP) treatment remains a clinical challenge because the pathophysiological mechanisms are not fully understood. Recently, it was verified that shifting microglial polarization toward the M2 phenotype reveals a potential strategy for CIBP treatment. Naringenin, a natural flavone flavonoid, has been reported to have antioxidant, anti-inflammatory and neuroprotective properties. However, the role of naringenin on regulating microglial polarization in CIBP rats and the molecular mechanisms participating in this process have not been fully clarified. Herein, we investigated the potential effect of naringenin on M1/M2 microglial polarization and further explored the potential mechanisms of this action. Our study demonstrated that intraperitoneal administration of naringenin could upregulate the antioxidative molecule glutathione peroxidase 4 (GPx4) level in the spinal cord, as well as bone cancer-induced mechanical allodynia in rats. Moreover, naringenin treatment also suppressed microglia-mediated neuroinflammation by downregulating the phosphorylation of nuclear factor xB (NF-xB) p65 expression and promoting microglial polarization toward the M2 phenotype in CIBP rats. The promoting effects mediated by naringenin on M1/M2 microglial polarization are dependent on the serine/threonine protein kinase adenosine monophosphate-activated protein kinase (AMPK)/ proliferator-activated receptor gamma coactivator-1 alpha (PGC-1 alpha) signaling pathway. Inhibition of AMPK activation with the classical AMPK inhibitor Compound C attenuated this effect of naringenin. These results improved the understanding of the anti-inflammatory property of naringenin on microglial polarization, which might provide new alternative avenues for CIBP treatment.
