Enrichment plots of gene expression signatures for NF-κB and MAPK signaling pathways. SY5Y cells were stimulated with 0 and 5 µmol/l STLC for 72 h. Gene-set enrichment analysis of the NF-κB and MAPK signaling pathways in SY5Y-treated cells. The green line represents enrichment score (GSEA gene set enrichment analysis), red represents more enrichment and blue represents less enrichment. STLC, S-trityl-L-cysteine; NF-κB, nuclear factor κB; MAPK, mitogen-activated protein kinase; 5U, 5 µmol/l; 0U, 0 µmol/l.
