The tongue is a heavily innervated and vascularized striated muscle that plays an important role in vocalization and swallowing. The surface of the tongue is lined with papillae which contain gustatory cells expressing various taste receptors. There is growing evidence to suggest our perceptions of taste and food preference are remodelled following chronic consumption of western diets rich in carbohydrate and fats. Our sensitivity to taste and also metabolism western diets may be a key factor in the rising prevalence of obesity but a systems-wide analysis is lacking. Here, we defined the proteomic landscape of the mouse tongue and quantified changes following chronic consumption of a chow or western diet for 7 months. We observed a dramatic remodelling of the tongue proteome including changes in fatty acid and mitochondrial metabolism. The expression of several receptors, and metabolic enzymes and hormones were also differentially regulated which is exciting as these may serve as novel therapeutic targets to potentially alter taste perception and food preference to combat obesity.
