A Call for Gene Expression Analysis in Whole Blood of Patients With Rheumatoid Arthritis (RA) as a Biomarker for RA-Associated Interstitial Lung Disease

J RheumatolPublished Mechanistic study

Authors' conclusion

All gene products of these genes (except for LINC02967) are known from the literature to be involved in the pathogenesis of fibrosis.

Study context
