Title : PMA treatment to stimulate EC secretion
Abstract :
- Treatment of HUVECs with PMA, a commonly used secretagogue, resulted in a characteristic morphological change indicative of activation
- A, immunofluorescence staining of vWF (green) and VE-cadherin (red) shows the exocytotic effect of PMA
- B, PMA increased protein secretion in the conditioned media as confirmed via immunoblotting
- C, relative to previous studies, more than twice as many secreted and plasma membrane proteins were identified
- D, overlay of intracellular and secreted proteins by means of difference gel electrophoresis
- In the left-hand panel, proteins in conditioned media of HUVECs are stained in green (+PMA) and red (−PMA), and cellular proteins are stained in blue
- Results were reproduced with different biological replicates using reverse-labeling (right-hand panel: red, +PMA; green, −PMA)
- The protein corresponding to von Willebrand antigen 2 is highlighted with a box
- Common proteins in the secretome and the cellular proteome are numbered in supplemental Fig
- S2 and listed in supplemental Table S3
