Evidences p(HGNC:BACE1, frag("67_78")) to a(HBP:"sAPP-alpha")

BI-1 treatment dose-dependently inhibited the release of both sAPPa and sAPPb in the conditioned medium (Figs. 2A and 3A). The 50% inhibitory concentrations (IC50) of BI-1 were about 1.5 mM for sAPPa and 0.9 mM for APPb, respectively. But BI-2, which is mainly composed of the core region BACE1 69–73, did not show the inhibitory effects

Surprisingly, BI-1 treatment resulted in a drastic, dose-dependent increase in the level of intracellular APPa (Figs. 2A and 3A). BI-3 also induced the accumulation of intracellular APPa until the concentration of BI-3 was raised to 12.5 mM; however, treatment of BI-3 with 25 mM decreased the level of intracellular APPa.

Taken together, these results show that BI-1 and BI-3 not only selectively reduce the level of APPbeta but also lead to the accumulation of APPalpha in cells with no change of full-length APP level.
