Gene expression data of NMDAR-E Associated with Ovarian Teratoma

Purpose: To identify significantly differentially expressed genes and to investigate the intricate molecular regulatory network underlying anti-NMDA receptor encephalitis associated with ovarian teratoma. Methods: This retrospective study analyzed ovarian teratoma samples from patients with and without NMDAR-E. We employed RNA sequencing for gene expression profiling. qPCR and Western blotting were used for gene and protein expression validation. Results: We identified 2524 significantly differentially expressed genes. The changes were notable in mRNA levels in ovarian teratomas associated with NMDAR-E. Functional enrichment analysis highlighted extracellular matrix and immune activation pathways. Key genes and proteins involved in ferroptosis and immune activation, including SLC40A1, GGH, FKBP11, CCDC80, and ANK3, showed significant expression differences.Conclusions: Our findings offer deeper insights into the pathophysiology of NMDAR-encephalitis associated with ovarian teratomas. The identified biomarkers, particularly in ferroptosis and immune activation pathways, provide potential targets for diagnosis and treatment.
