IFITM1 and dermatomyositis: In the current research, a large number of bioinformatic analysis tools have been used to identify five hub genes (TRIM22, IFI6, IFITM1, IFI35, and IRF9) between PM/DM and health control subjects on the basis of gene expression profiles attained from GSE1551 (DM), GSE3112 (PM), GSE39454 (DM), GSE39454 (PM), GSE46239 (DM), GSE128470 (DM), and GSE128470 (PM) datasets.
