摘要
Hand-foot syndrome (HFS) is a major adverse reaction to capecitabine (CAP). The exact pathogenesis of this disease remains unclear. In this study, metabolomics combined with cell RNA sequencing was used to study the mechanisms of CAP-induced HFS. The murine model of HFS was constructed by intragastric administration of CAP or its metabolites. Quantitative reverse transcription polymerase chain reaction and enzyme-linked immunosorbent assays were used to verify the mechanisms. Metabolomics showed the phosphatidylinositol signaling pathway and amino acid and fatty acid metabolism to be the major metabolic alterations related to the occurrence of HFS. Transcriptomics profiles further revealed that the cytokine-cytokine receptor interaction, IL17 signaling pathway, Toll-like receptor signaling pathway, arachidonic acid metabolism, MAPK signaling pathway, and JAK-STAT3 signaling pathway were the vital steps in skin toxicity induced by CAP or its metabolites. We also verified that the inflammation mechanisms were primarily mediated by the abnormal expression of interleukin (IL) 6 or IL8 and not exclusively by COX-2 overexpression. Finally, the P38 MAPK, NF-κB, and JAK-STAT3 signaling pathways, which mediate high levels of expression of IL6 or IL8, were identified as potential pathways underlying CAP-induced HFS.
