Frontiers in Physiology retracted a diabetic kidney disease article after concerns were raised about image integrity in published figures. The retraction notice targets a 2021 paper describing a TRIM18-regulated STAT3 signaling pathway purported to drive renal EMT, inflammation and fibrosis in diabetic kidney disease. The journal cited an investigation into figures and noted that the authors were given an opportunity to respond during the process. For readers, the retraction reinforces the importance of raw data availability and figure provenance checks in preclinical mechanistic work. For industry teams using the literature for target selection, this also functions as a reminder to re-evaluate key assumptions tied to retracted mechanistic pathways.
