Inhibition of the cleavage of domain D1 from domain D1D2D3 of u-PAR by BB94 in the supernatants and on the cell surface of hMVECs.
(A) The hMVECs were stimulated with or without 10−8 M phorbol ester PMA in the absence or presence of 10 μg/mL BB94 for 24, 48, or 72 hours or (B) the combination of 10 ng/mL bFGF and 10 ng/mL TNF-α in the absence or presence of 10 μg/mL BB94 for 72 hours. Supernatants were collected, and Triton X-100 cell lysates were prepared (only after 72 hours [C]). Immunoprecipitation and Western blot analysis were performed as described in “Materials and methods.” CM indicates conditioned medium.
