Figure Lengend Snippet: Comparison of RT4 cells and ALDH1L1-deficient clones based on all peaks from untargeted metabolomics data. PCA ( A ) and OPLS-DA ( B ) between all groups with the CRISPR and 572 clones clustered closely (R2X: 0.920, R2Y: 0.981, Q2: 0.808). ( C ) A heat map (generated using MetaboAnalyst 5.0 ) of measured metabolites (13,339 total, ) demonstrates significant differences between groups’ metabotypes, with WT RT4 cells and clone 506 being most distant and CRISPR and 572 clones being the farthest apart. The heatmap is auto-scaled (mean-centered and divided by standard deviation) for each variable; n = 5 per group (RT4 cells) and 6 per groups for each clone. Orange colors represent higher auto-scaled values whereas blue colors represent lower auto-scaled values. Colors for experimental groups are as follows: 506, red; 572, green; L1-CR, dark blue; WT, cyan. Hierarchical clustering was performed on samples in MetaboAnalyst 5.0 using Euclidean distance measures. Each sample number (as in ) is indicated at the bottom of the heatmap.
