mGluR1 and mGluR5 mRNA expression in the hippocampus and cortex in rats.

<p>The bars indicate the mean ± SD (<i>n</i> = 8). ^a<i>p</i><0.05, ^b<i>p</i><0.01, compared with control rats;^c<i>p</i><0.05, compared with fluoride group; ^d<i>p</i><0.05, compared with arsenic group. Panels a, b and c represent mGluR1, mGluR5 and β-actin mRNA expression in the hippocampus. Panels d, e and f represent mGluR1, mGluR5 and β-actin mRNA expression in the cortex. M: marker. The size from top to bottom is 600, 500, 400, 300, 200, and 100 bp, respectively. The PCR product for mGluR1, mGluR5 and β-actin was 100, 138 and 115 bp, respectively.
