FFAR2 and Alzheimer disease: Western blotting and qRT-PCR analyses revealed statistically significant decrease in GPR43 expression in the AD group compared to controls, in both cortex (Western blot: 0.57 ± 0.04; qRT-PCR: 0.46 ± 0.12) and hippocampus (Western blot: 0.58 ± 0.04; qRT-PCR: 0.44 ± 0.13) (Fig. 1B-G).
