Principal component analysis (PCA) plots for lung tissue RNA sequencing data and volcano plots of differential expression results. Principal component analysis (PCA) plots for lung tissue RNA sequencing data and volcano plots of differential expression results. A PCA plot for control samples (orange) vs. IPF samples (blue). B PCA plot for control samples (orange) vs. COPD samples (blue). C Volcano plot of IPF vs. control differential expression results. FDR < 0.01 results shown in blue and results that did not meet FDR threshold are shown in orange. D Volcano plot of COPD vs. control differential expression results
