TGF-β1 reduces VEGFR2 expression via multiple mechanisms. a Western blot showing TGF-β1 induced loss of cell associated VEGFR2 protein and concomitant increase in full-length VEGFR2 detected in conditioned medium. b Quantitative PCR analysis showed that there was no change in the relative ratio of full length VEGFR2 mRNA to alternative spliced sVEGFR2 mRNA upon TGF-β1 treatment. c TGF-β1 treatment induced increased expression of ADAM family sheddase enzyme ADAM 10. TGF-β1 treatment had no effect on the expression of ADAM 17 or the membrane-associated metalloproteinase MMP-14. d Ultracentrifugation of endothelial conditioned medium demonstrated that soluble VEGFR2 is associated with the extracellular vesicle/exosome marker HSP90 in TGF-β1 treated cells
