We set out to determine if the constitutive\r\nrelease of subendothelial VWF is actually regulated and if so, what functional consequences this might\r\nhave.\r\nConstitutive VWF secretion can be increased by a range of factors; changes in VWF expression, levels\r\nof TNF-alpha or other environmental cues. An RNAseq analysis revealed that expression of RGS4\r\n(Regulator of G protein signalling 4) was reduced in endothelial cells (HUVECs) grown under these\r\nconditions. si-RGS4 treatment of HUVECs increased constitutive basolateral secretion of VWF,\r\nprobably by affecting the anterograde secretory pathway. In a simple model of endothelial damage\r\nwe show that RGS4-silenced cells increased platelet recruitment onto the subendothelial matrix under\r\nflow. These results show that changes in RGS4 expression alter levels of subendothelial VWF, affecting\r\nplatelet recruitment. This introduces a novel control over VWF function."^^<http://www.w3.org/2001/XMLSchema#string> . <https://discovery.ucl.ac.uk/id/eprint/10103547> <http://purl.org/dc/terms/date> "2020-07" .
