ILK KO hepatocytes are protected against Jo-2 induced apoptosis in vitro. A) Caspase 3/7 activity at 6 h after treatment of WT and ILK KO hepatocytes with Jo-2 (0.5 μg/ml) and Actinomycin D (0.05 μg/ml). Fold change is the ratio of luminescence value of treatment group with its corresponding no treatment group. B) Effect of ERK1/2 inhibition using a MEK inhibitor U0126 (20 μM). Representative Western blots of cleaved caspase and PARP 6 h after Jo-2, vehicle or Jo-2+inhibitor administration. (Akt Inh: Akt inhibitor LY-294002, ERK Inh: ERK inhibitor U0126) C) Representative Western blots showing inhibition of phosphorylation of ERK1/2 by U0126 in ILK KO hepatocytes after 6 h after treatment with U0126. D) Representative Western blots of PARP after inhibition of NFκB using a synthetic peptide 6 h after treatment with Control peptide (CP), CP+Jo-2 and NP+Jo-2 (NFκB peptide). (CP: control peptide, NP: NFκB peptide). E) Total FAK and p-FAK at 0 and 6 h after Jo-2 administration in vitro. F) Total FAK and p-FAK at 0 and 6 h after Jo-2 administration in vivo.
