Crohn's disease and ulcerative colitis are inflammatory bowel diseases (IBDs)
with high prevalence in humans. Carnosic acid (CA) has been reported to possess
antioxidative properties; however, its role in IBDs has not been determined. In
the present study, we found that CA significantly prevented the loss of body
weight and shortening of colon length in acute colitis induced by dextran sodium
sulfate (DSS). Pronounced infiltration of immune cells and a loss of crypt
architecture and goblet cells were ameliorated by CA. CA significantly decreased
the activity of MPO and infiltration of F4/80(+) macrophages in the colon.
DSS-induced pro-inflammatory cytokine mRNA and protein levels in the colon were
also attenuated by CA. CA decreased the activation of p65 and c-Jun signalling.
CA inhibited DSS-induced NLRP3 inflammasome activation by reducing caspase 1
activity. In addition, CA increased the level of Nrf2 and prevented the
degradation of Nrf2 via ubiquitination by blocking the interaction between
Cullin3 and Keap1, which resulted in the decrease of Nrf2 target genes. Finally,
GSH levels and SOD activity were increased after CA treatment, while MDA and iNOS
levels were significantly reduced. Taken together, our data showed that CA may be
useful as a potential therapeutic candidate for IBDs.
