Endothelial Cell Characterization Protocol

Immortalized human endothelial cells (EAhy926, ATCC), mouse macrophage-like cells (RAW264.7, ATCC), and HEK293 cells were maintained in DMEM supplemented with 10% fetal bovine serum (FBS, Hyclone). Angiotensin II was purchased from Sigma. MRP8 promoter-luciferase constructs (Grebhardt et al., 2012 (link)) and BRG1 expression constructs (Li et al., 2019a (link)) have been previously described. Small interfering RNAs were purchased from Dharmacon. PFI-3 was purchased from Selleck. Transient transfections were performed with Lipofectamine 2000. Luciferase activities were assayed 24–48 h after transfection using a luciferase reporter assay system (Promega) as previously described (Li et al., 2019c (link)). For conditioned media (CM) collection, the cells were switched to and incubated with serum-free media overnight. The next day, the media were collected, centrifuged at 4000 × g for 30 min at 4°C using 3-kDa MW cut-off filter units (Millipore) and sterilized through a 0.4-μm filter.
