This, in turn, inhibited IL-1β-induced cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) expressions, thereby, indicating that ellagic acid could also modulate the oxidative stress (Lin et al., 2020), implicated in osteoarthritis (Sokolove and Lepus, 2013). The gene discussed is NOS2; the disease is osteoarthritis.
