Our results indicate that for mesothelioma cell lines only, there was a positive correlation between CDH1 mRNA levels and PND-1186 IC50 values that was both statistically and clinically significant (Spearman’s rho value is 0.6432, p-value is 1.554 × 10−7, and slope of the linear regression fit is 0.1556). This evidence concerns the gene CDH1 and mesothelioma.
