Identification of potential biomarkers for idiopathic pulmonary fibrosis and validation of TDO2 as a potential therapeutic target

Figure 3 Correlations between lung gene expression and forced vital capacity and diffusing capacity. A-M: TDO2, RET, TGFB3, SULF1, ASPN, ALDH1A3, COL3A1, COL1A2, KCNMA1, COL5A2, KCNN3, KCNN4 and AOX1 expression was negatively correlated with diffusing capacity of carbon monoxide (DLCO); N-P: HSD17B6, SDR16C5, and KCNMB4 were significantly positively correlated with DLCO. The Pearson correlation metric was computed by using the ‘stat_cor’ function in R. DLCO: Diffusing capacity of carbon monoxide.
