%X <B>BACKGROUND: </B>The association between acquired ADAMTS13-deficient thrombotic thrombocytopenic purpura (aTTP) and systemic lupus erythematosus (SLE) has been studied; however, the underlying molecular causes remain poorly understood. This research aimed to employ bioinformatics approaches to elucidate potential molecular mechanisms contributing to the pathogenesis of SLE and aTTP.<BR><B>METHODS: </B>The Gene Expression Omnibus (GEO) database yielded GSE121239 and GSE36418 to get mutual different expression genes (DEGs). Subsequently, DEGs were subjected to process Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Then, the DEGs were used for protein-protein interaction (PPI) analysis and screened for hub genes and drugs by the DGIDB drug database.<BR><B>RESULTS: </B>A total of 87 DEGs between the SLE and TTP datasets were identified. In the GO and KEGG analyses, DEGs were mainly enriched in the "regulation of transcription by RNA polymerase II" and "signaling pathways regulating pluripotency of stem cells." After a PPI analysis, three hub genes (BMPR2, SMAD5, and ATF2) were identified. Finally, two drugs targeted to ATF2 were predicted by the DGIDB drug database.<BR><B>CONCLUSIONS: </B>Three core genes were linked to the molecular pathogenesis of SLE and aTTP, and two drugs may be viable treatments for both diseases.
