GC/MS-Based Metabolomics Reveals Biomarkers in Asthma Murine Model Modulated by Opuntia humifusa

Figure 4

PCA score plots derived from GC/MS data of serum samples between control and dexamethasone treatment group (a) and control and O. humifusa treatment group (b), suggesting metabolic differences according to different treatments after OVA induction. Panel (c) shows box plots of identified metabolites contributing to differentiation in the PLS-DA model (VIP > 1.2 and p < 0.05). The PLS-DA model was validated by a permutation test (n = 200). OH, Opuntia humifusa.
