(c) High-content analysis of poly-Ub and CHOP induction upon treatment with VCP inhibitors. HeLa cells were treated with increasing doses of the indicated compounds. Cells were then fixed and immunostained with the indicated antibodies. Cell numbers and mean fluorescence intensity (MFI) were determined using the ArrayScan platform. Data were collected in triplicate (n = 3), and error bars represent s.d. AU, arbitrary units.
