Western blot of sLOX-1 released from cells treated with MβCD and different protease inhibitors.
LOX-1-V5-COS transfected cells were incubated with MβCD, GM6001, PMSF, Pepstatin A and the protease inhibitor cocktail (PI mix) (Calbiochem), as indicated (upper panel). Histogram shows the densitometric analysis expressed as percentage of reduction of sLOX-1 released in the presence of different protease inhibitors. 100% refers as sLOX-1 released in the presence of 5mM MβCD for 30 min (lower panel). Data in histograms represent the average ± SEM of three experiments, P < 0.05 (*), P < 0.01 (**) or P < 0.001 (***).
