PDF file, 96K, 1A. Expression of HH pathway components in non-tumoral pleural tissue and mesothelioma tumors. Quantitative real-time PCR analysis of SMO, GLI2, IHH, DHH gene expression in non-tumoral pleural tissue (NT) and tumor (T). 1B. Overall survival is inversely correlated with high GLI1 expression (delta Ct below the median) (p=0.042, low GLI1: median survival 22.9 months, 95% confidence interval 0.4- 45.4 months; high GLI1: median survival 17.0 months, 95% confidence interval 9.0- 25.1 months ).
