Hs. Cho et al., AGE-RELATED-CHANGES OF MESSENGER-RNA EXPRESSION OF AMYLOID PRECURSOR PROTEIN IN THE BRAIN OF SENESCENCE-ACCELERATED MOUSE, Comparative biochemistry and physiology. B. Comparative biochemistry, 112(2), 1995, pp. 399-404
APP695 mRNA is only expressed in the brains of SAM. The expression of
APP mRNA in SAM P1 mice brains is more marked than that in SAM R1 mice
brain. APP mRNA expression was increased with advancing age in all br
ain regions of SAM P1 mice compared with SAM R1, Especially, the chang
es of the amount of APP mRNA in the prosencephalon and the mesencephal
on are significant at P value of 0.05. We suggest that overexpression
of APP mRNA may be related to accelerated aging phenomenon in the SAM
brain. This is the first report of age-related increase in the amount
of APP mRNA in the SAM brain.
