IL-13Rα2 expression is upregulated in pancreatic tumors but not in organs of mice after treatment with HDAC inhibitor, SAHA. A, qRT-PCR of human IL-13Rα2 in implanted pancreatic tumors after SAHA and IL-13-PE treatment. Tumors were harvested next day after IL-13-PE treatment and total RNA extracted. Data shown is ratio of human IL-13Rα2/β-actin expression and multiplied by 1000 for convenience. Bars, SD of triplicate determinations. B, qRT-PCR of mouse IL-13Rα2 in mice organs after SAHA and IL-13-PE treatment. Tissues were harvested at the same time point as in panel A and total RNA extracted. Data shown is ratio of mouse IL-13Rα2/β-actin expression and multiplied by 100 for convenience. C, IHC of human IL-13Rα2 in implanted pancreatic tumors after SAHA and IL-13-PE treatment. D, IHC of mouse IL-13Rα2 in mice organs after SAHA and IL-13-PE treatment. Liver, brain, kidney, pancreas, lung and spleen were fixed for immunostaining of mouse IL-13Rα2 as visualized by Alexa555. Nucleus was counterstained by DAPI.
