"We examined the effect of the three human isoforms of apolipoprotein E (ApoE2, ApoE3, and ApoE4) on the canonical Wnt signaling pathway in undifferentiated PC12 cells," wrote A. Caruso and colleagues, Roma La Sapienza University.
"Addition of recombinant ApoE4 reduced Wingless-Int7a-stimulated gene expression at concentrations of 80 and 500 nm. Recombinant ApoE2 and ApoE3 were virtually inactive. Recombinant ApoE4 also inhibited Wnt signaling when combined with very low density lipoproteins (VLDLs) or in cells...
