MPO and colitis: We further studied the antioxidant and anti-inflammatory activity of OJe through an animal model resembling colitis (Fusco et al., 2017) in which it counteracted cytokine generation, nuclear factor kappa B (NF-kB) activation, nitrotyrosine and poly ADP-ribose (PAR) formation, as well as enhanced myeloperoxidase (MPO) activity, increased manganese-dependent superoxide dismutase (MnSOD) expression and modulated both pro- and anti-apoptotic factors.
