MMP9 and asthma: We mainly presented the molecular docking results of the major hub genes for asthma, such as CASP3, PTGS2, EGFR, and MMP9 (Figure 3B), as well as the major hub genes for COPD, ESR1, PPARG, and CTSN (Figure 4B), with some of these phthalates (The detailed spatial structure of all dockings can be found in the Supplementary Material).
