RT-PCR analysis of α-secretase ADAM17, the γ-secretase components and β-secretase BACE1 in presence of PC-PL 18 : 1 and PC-PL 20 : 4 compared to the corresponding phospholipids PC 18 : 1 and PC 20 : 4 as control. The abbreviations set are ADAM17 = α-secretase, PSEN1 = presenilin1, PSEN2 = presenilin2, APH1a = anterior pharynx-defective 1a, APH1b = anterior pharynx-defective 1b, NCSTN = nicastrin, PSENEN2 = presenilin enhancer 2, and SEM = standard deviation of the mean. Statistical significance was determined by two-tailed Student's t-test.
