Differential metabolites were annotated to metabolic pathways using the KEGG database (https://www.kegg.jp/kegg/pathway.html). Pathway enrichment analysis was performed using the Python scipy.stats package, and the biological pathways most associated with the experimental treatment were identified via Fisher's exact test.

Mobile phase A consisted of water/acetonitrile (95/5, v/v) with 0.1% formic acid, while mobile phase B was acetonitrile/isopropanol/water (47.5/47.5/5, v/v/v) containing 0.1% formic acid. The flow rate was maintained at 0.40 mL/min, and the column temperature was set at 40.

Simultaneously, the MS and MS/MS spectral information was matched against public metabolomics databases, including HMDB (http://www.hmdb.ca/) and METLIN (https://metlin.scripps.edu/), as well as the Majorbio in-house library, to obtain metabolite identification.
The searched data matrix was uploaded to the Majorbio Cloud Platform (cloud.majorbio.com) for further analysis. First, the data matrix underwent preprocessing as follows: Missing values were filtered using the 80% rule, meaning variables with non-zero values in at least 80% of the samples within one group were retained. Subsequently, missing values were imputed using the minimum value from the original matrix. To mitigate errors arising from sample preparation and instrument instability, the response intensity of the mass spectrometry peaks was normalized using the sum normalization method, yielding a normalized data matrix. Variables with a relative standard deviation (RSD) in QC samples exceeding 30% were removed, and the data were log10 transformed to obtain the final data matrix used for subsequent analysis.
Second, the processed data matrix was subjected to Principal Component Analysis (PCA) and Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA) using the ropls package (Version 1.6.2) in R software. Model stability was evaluated using 7-fold cross-validation. Significantly differential metabolites were selected based on the Variable Importance in Projection (VIP) derived from the OPLS-DA model and Student’s t-test p-values; metabolites with VIP > 1 and p < 0.05 were defined as significantly differential.
