Figure 4. Pdro knockdown increases plasma membrane projections and cholesterol esterification.
(A) Images of Filipin staining of SHEP cells treated for 72h with siPdro or scramble siRNA. Cholesterol-rich plasma membrane ruffles are indicated by arrows and filipodia by arrowheads. (B) Rate of cholesterol esterification in SHEP cells pre-treated for 72h with the indicated siRNA, followed by loading or not with 100 µg/ml AcLDL for 8h in the presence of [3H]oleate in lipoprotein-deficient serum. One representative experiment in triplicate wells is shown (*, p≤0.05 using Mann Whitney test).
