Protocol outline. Confluent cells (HUVEC, Cav-1 siRNA transfected HUVEC and HCAEC) were exposed to either helium (70%) or control gas for 20 minutes in a specialised temperature controlled gas chamber. Cells were harvested either directly after treatment or after 2, 4, 6, 12 and 24 hours respectively. HUVEC = human umbilical vein endothelial cells. HCAEC = human coronary artery endothelial cells.
