1 Fluo-3 staining used in flow cytometry and video microscopy revealed an oxysterol-induced Ca(2+) influx, varying according to the oxysterol studied, leading to the activation of the MEK/ERK1/2 pathway as demonstrated by Western blot analysis. Oxysterols mitogen-activated protein kinase 3 Homo sapiens
