In order to revel potential hub genes involved in the pathogenesis of Chinese type 1 diabetic patients, GSE55100 has been also downloaded to identify DEGs, and thirteen hub genes (MMP9, ARG1, CAMP, CHI3L1, CRISP3, SLPI, LCN2, PGLYRP1, LTF, RETN, CEACAM1, CEACAM8, and MS4A3) were retrieved by module analysis [32]. Here, CHI3L1 is linked to type 1 diabetes mellitus.
