Shared and Distinctive Transcriptomic and Proteomic Pathways in Adult and Juvenile Dermatomyositis

Arthritis RheumatolPublished Mechanistic study

Authors' conclusion

The combination of proteomics and transcript expression by multi-enrichment analysis broadened the identification of up- and down-regulated pathways among active DM and juvenile DM patients.

Study context

Population
Active adult dermatomyositis (DM) and JDM patients receiving immunosuppressive therapies; peripheral blood
Comparison
Adult DM and JDM patients vs matched healthy controls
  • DMn = 14
  • Juvenile DMn = 12
Outcome
Transcript and protein expression: gene locus and pathway regulation in peripheral blood
Methodological detailsmatched healthy controls, multi-enrichment analysis
  • Matched healthy controls
  • Multi-enrichment analysis

Main finding
