Correction of cholesterol accumulation in βarr2-overexpressing cells with Rp-cAMPS (50 μM). (A) Representative image of untreated GFP-expressing (control-GFP) cells stained for endogenous free cholesterol (filipin). (B) Representative image of untreated βarr2-GFP cells stained for cholesterol (filipin). (C) Representative image of βarr2-GFP cells treated with Rp-cAMPS (50 μM) for 72 h and stained for cholesterol (filipin). Images are representative of at least 15 images for each condition taken over four separate experiments.
