Figure 6From: Presenilin-1 regulates induction of hypoxia inducible factor-1α: altered activation by a mutation associated with familial Alzheimer's diseaseNormal activation by IGF-1 and insulin of PI3K/Akt in Psen1-/- fibroblasts. Immortalized fibroblast cell lines were treated with IGF-1 (A) or insulin (B) for the indicated times. Western blotting was performed for p-Akt (Ser473) followed by reprobing for total Akt. Panels show representative blots from experiments that were performed multiple times.Back to article page
