The effects of other potential AhR ligands (or mixtures containing AhR ligands) such as polychlorinated biphenyls (Wahlang et al. 2013, 2014; Shan et al. 2015), cigarette smoke (Mallat and Lotersztajn 2009), and diesel particles (Arciello et al. 2013) have been tested on different mouse models of obesity. This evidence concerns the gene AHR and obesity disorder.
