Fig. 3From: Untargeted metabolomics reveals alternations in metabolism of bovine mammary epithelial cells upon IFN-γ treatmentHeatmap of the differentially expressed metabolites (DEMs) in negative (a) and positive (b) ion modes. DEGs were screened out according to |log2Ratio|≥ 1 with false discovery rate (FDR) ≤ 0.01. Red rectangles indicate upregulated metabolites and blue rectangles indicate downregulated metabolites. (-), negative ion mode. ( +), positive ion modeBack to article page
