From: Metabolomic profiling identifies distinct phenotypes for ASS1 positive and negative GBM
Cross-validated scores, first predictive score (tcv[1]), based on the final OPLS-DA models showing an almost complete separation of ASS+ve cell lines (T98G and U118; grey) and ASS-ve cell lines (GAMG, LN229 and SNB19; black) for (a) 1D GC-TOFMS data cell supernatant (p = 1.84*10− 5) and (b) 1D GC-TOFMS data cell pellet (p = 0.03) and (c) 2D GC-TOFMS data cell supernatant (p = 0.0007) and (d) 2D GC-TOFMS data cell pellet (p = 0.004)
