SC79 induces the shedding of the RAGE ectodomain. HAECs were incubated with 10 µM SC79 for various times (5, 10, 30, and 60 min) (n = 4) (A) or different concentrations of SC79 (0.1, 1, 5, and 10 µM) for 30 min (n = 3) (B). The cell lysate and culture supernatant were immunoblotted with a monoclonal antibody to the extracellular domain of human RAGE and an anti-actin antibody. To compare the size of RAGE in cell lysate and culture supernatant, untreated cell lysate (a) and conditioned media from cells treated with 10 µM SC79 for 30 min (b) were run on the same gel and immunoblotted with the RAGE antibody (C). The cell lysates of HAECs treated with different concentrations of SC79 (0.1, 1, 5, and 10 µM) for 30 min were immunoblotted with an antibody to the C-terminal domain of human RAGE and an anti-actin antibody (n = 4) (D).
