Figure 6

Western blots of the 80 kDa Notch-1 intracellular domain (NICD) and N-cadherin/CTF2.A) Notice that, with the exception of 3 PSEN mutation cases (Y115C/PSEN1, N141I/PSEN2 and P264L/PSEN1), all the PSEN mutations have reduced quantities of NICD transcription factor. In the SAD cases, there is a heterogeneous distribution of NICD, being almost negligible in one SAD case, elevated in a second case and diminished in the remaining two, relative to the ND controls. B) The amount of N-Cadherin holoprotein detected at 110 kDa is reduced in all PSEN cases relative to the ND controls. A similar pattern is observed for the SAD cases. The N-Cad/CTF2 band at 28 kDa is decreased in all PSEN mutations with the exception of A260V and M146L mutations that displayed higher values. The quantities of the N-Cad/CTF2 were variable in the SAD relative to the ND levels. SAD = sporadic Alzheimer's disease; ND = non-demented.
