cAMP-dependent protein kinase (PKA) activity in the extracts of Alzheimer disease (AD) and control brains. (a) PKA activity of the 16 000 g extract of the medial temporal cortex from six AD and seven age-matched control brains was assayed in the absence or presence of 5 μmol/L cAMP. (b) Ratio of PKA activity in the absence or in the presence of cAMP. *p < 0.05 as compared with the control group.
