Extended Data Fig. 1: De novo serine synthesis pathway in human B cell lymphoma.

a, Bar graphs presenting the functional gain (red) or loss (blue) of SHMT2 located on chromosome 12 by DNA copy number analysis of 568 DLBCL and 176 FL tumors. b, The frequency of loss (blue), gain (red) or diploid (black) status of serine synthesis pathway genes in 568 human DLBCL and 176 human FL tumors. c, Diagrams demonstrating the overlaps of amplification (red) and loss (blue) of SHMT2 vs other serine biosynthesis pathway enzymes (PSPH, PHGDH, PSAT1, SHMT1) in 568 DLBCL and 176 FL tumors. d, Bar graph showing the frequency of SHMT2 amplification in different subtype (GC-like, ABC-like or unclassified) of 249 human DLBCL tumors.
