Exploring mitochondrial and ferroptotic mechanisms for systemic lupus erythematosus biomarker identification and therapy.

ABSTRACT: Systemic lupus erythematosus (SLE) is a complex autoimmune disease with heterogeneous clinical manifestations. Understanding the molecular mechanisms of SLE is crucial for developing effective therapeutic strategies. This study downloaded microarray datasets from the Gene Expression Omnibus (GEO) database. Single-cell RNA sequencing (scRNA-seq) data was processed to identify 19 clusters and annotated five major cell types. Then we calculated mitochondrial-related genes (MRGs) and ferroptosis-related genes (FRGs) scores. FRGs scored the highest in Megakaryocytes, while MRGs scored the highest in B cells. By employing pseudotime analysis, cell-cell communication analysis, and Single-Cell Regulatory Network Inference and Clustering (SCENIC) analysis, we explored the heterogeneity of cells in
