Fig 7. Hook3 knockdown increases production of endogenous β-amyloid in N2A cells.
(a) N2A cells were transfected with two different siRNAs targeting Hook3 and with non-target siRNA as control (n = 3). Beta-amyloid accumulated for 48h in cell culture media was quantified by a murine amyloid-specific ELISA. Hook3 downregulation by two different siRNAs causes a 35% increase in secreted β-amyloid. * p < 0.05 compared to control group with student’s t-test. Data are means ± SD. (b) Western blot analysis of cell lysates demonstrate that transfection with Hook3 siRNA does not alter the levels of intracellular APP, BACE1 and PS1.
