Expression of PG receptors mRNA in rat hippocampus (n = 4). The mRNA expression of PG receptors was measured by RT-PCR. The middle band on the PCR images is a marker. The relative mRNA level of PG receptors was standardized to endogenous β-actin mRNA for each sample. Data are expressed as mean ± SD of four individual experiments. Al administration induced a significant increase of EP2, EP4, DP1 and IP levels and a significant decrease of EP3, FP and TP levels compared with the control group (∗P < 0.05).
