Fig. 4From: Mice null for the deubiquitinase USP18 spontaneously develop leiomyosarcomasUSP18−/− leiomyosarcoma cell lines are sensitive to IFNβ and clinically-achievable concentrations of doxorubicin. a and b: Cell growth and apoptosis analysis of KHC-1 and KHC-2 cells treated with IFNβ (500 units/mL). c and d: Cell growth and apoptosis analysis of KHC-1 and KHC-2 cells treated with 0.2 μM doxorubicin (Dox). Analyses were done at 24, 48 and 72 h post-treatment for both doxorubicin and IFNβBack to article page
