Kynurenine metabolites in plasma of CMM (PRE&TRM) compare to healthy controls. (A) The concentrations of KYN, TRP and (B) KYNA, 3-HK, AA, 3HAA, and XA were determined on plasma samples derived from healthy volunteers (HC, n = 5) and metastatic CMM patients, before (PRE) and during the first treatment (TRM) with MAPKIs (n = 5). TRP, tryptophan; KYN, L-kynurenine; KYNA, kynurenic acid; AA, anthranilic acid; 3-HK, 3-hydroxykynurenine; 3HAA, 3-hydroxyanthranylic acid; XA, xanthurenic acid; CMM, cutaneous; UM, Unknown Melanoma. **p < 0.005; Corrected P-Values (Bonferroni).
