SPN and systemic lupus erythematosus: We consider the gene expression pattern of FOXM1, which is a master regulator for cell cycle and cell survival (19), as a prototype of SLE plasmablast-specific genes; hence, we conducted an analysis of find similar entities for FOXM1 from DEGs in the CD38+CD43+ B cell subset to determine the genes that are significantly/uniquely upregulated in CD38+CD43+ B cells of SLE patients.
