Pyrroloquinoline quinone attenuates isoproterenol hydrochloride‑induced cardiac hypertrophy in AC16 cells by inhibiting the NF‑κB signaling pathway

Pyrroloquinoline quinone (PQQ) is a naturally occurring redox co‑factor that functions as an essential nutrient and antioxidant, and has been reported to exert potent anti‑inflammatory effects. However, the therapeutic potential of PQQ for isoproterenol hydrochloride (Iso)‑induced cardiac hypertrophy has not yet been explored, at least to the best of our knowledge. In the present study, the anti‑inflammatory effects of PQQ were investigated in...
