Implication of TRPC3 channel in gustatory perception of dietary lipids
Aim The pathogenesis of obesity has been associated with high intake of dietary fat, and some recent studies have explored the cellular mechanisms of oro-sensory detection of dietary fatty acids. We further assessed the role of transient receptor potential canonical (TRPC) channels in oro-sensory perception of dietary lipids. Methods We determined by RT-qPCR and western blotting the expression of TRPC3/6/7 channels in mouse fungiform taste bud cells (mTBC). Immunocytochemistry was used to explore whether TRPC3 channels were co-expressed with fatty acid receptors. We employed wild-type (WT) mTBC, and those transfected with small interfering RNAs (siRNAs) against TRPC3 or STIM1. Ca2+ signalli…
