N6-methyladenosine (m6A) has been implicated in immune regulation and disease progression, yet its role in disrupting immune homeostasis in SLE, particularly in CD4+ T-cell differentiation, remains poorly understood. In the present study, m6A-modified RNA immunoprecipitation sequencing (m6A-seq) and RNA sequencing (RNA-seq) of peripheral blood mononuclear cells from patients with SLE identified serine/threonine protein kinase 25 (STK25) as a candidate gene exhibiting abnormal m6A modification, and its expression was subsequently validated using reverse transcription-quantitative (RT-q)PCR. CD4+ T cells isolated from MRL/lupus-prone mice underwent lentiviral-mediated STK25 knockdown, and glycolytic activity was evaluated through measuring glucose uptake and lactate production. Western blotting and RT-qPCR demonstrated that STK25 knockdown reduced the expression of glycolysis-associated genes (glucose transporter 1, hexokinase 2, pyruvate kinase M2 and lactate dehydrogenase A) and the Treg-specific transcription factor Foxp3, while increasing the expression of the Th17- and Th2-associated transcription factors, RORγt and Gata3. Flow cytometry further confirmed enhanced differentiation of Th17 and Th2 cells accompanied by a reduction in Treg cells, indicating disruption of immune homeostasis. Collectively, these findings suggested that aberrant m6A modification contributes to the downregulation of STK25 expression, thereby promoting glycolytic reprogramming and CD4+ T-cell subset imbalance in SLE. STK25 may therefore represent a potential therapeutic target for restoring immune homeostasis in SLE.","dates":{"publication":"2026/06/04"},"accession":"GSE334206","cross_references":{"GSM":["GSM9783360","GSM9783364","GSM9783353","GSM9783363","GSM9783352","GSM9783351","GSM9783362","GSM9783361","GSM9783350","GSM9783346","GSM9783357","GSM9783356","GSM9783355","GSM9783354","GSM9783365","GSM9783349","GSM9783348","GSM9783359","GSM9783358","GSM9783347"],"GPL":["24676"],"GSE":["334206"],"taxon":["Homo sapiens"]}}
