Correlation analysis between these DEGs and AKI biomarkers (Cystatin C, NGAL, NAG, and KIM-1) was conducted using the GEPIA tool, revealing significant correlations (p < 0.05) for CDK1, STAT1, COL1A2, and COL1A1, as illustrated in Figures 1A–C. The gene discussed is COL1A2; the disease is acute kidney injury.
