Figure 4From: Effects of dietary Na+ deprivation on epithelial Na+ channel (ENaC), BDNF, and TrkB mRNA expression in the rat tongueNormalized expression of BDNF and TrkB mRNA in the rat fungiform, vallate and foliate taste buds. Expression levels were normalized to each sample's respective GAPDH expression and reported as a fold of control. In sodium deprived rats, BDNF mRNA expression in fungiform taste buds was significantly downregulated. n indicates the number of animals used in the experiments. * p < 0.05.Back to article page
