AHR and renal fibrosis: Our previous publications have demonstrated that some compounds such as matairesinol, rhoifolin, 5,6,7,8,3′,4′-hexamethoxyflavone, 5,7,3′,4′,5′-pentahydroxy flavanone and erythro-guaiacylglycerol-β-ferulic acid ether attenuated renal fibrosis by suppressing AHR signalling (Miao et al., 2020; Cao et al., 2022; Miao et al., 2022).
