Ankrd1 as a potential biomarker for the transition from acute kidney injury to chronic kidney disease.

ABSTRACT: Ischemia-reperfusion injury (IRI) is one of the leading causes of acute kidney injury (AKI), predisposing patients to chronic kidney disease (CKD) due to maladaptive renal repair. Nevertheless, the molecular mechanisms and biomarkers that cause maladaptive repair remain unclear. In this study, we used single-nucleus RNA sequencing data from GEO database (GSE139107) to identify molecular markers during the transition from AKI to CKD caused by IRI. Analysis of intercellular crosstalk, trajectory and machine learning algorithms revealed hub cell clusters and genes. Proximal tubule (PT) cells, especially a new cluster (New PT2), significantly interacted with fibroblasts during the transition. The expression levels of hub genes were validated using the bulk RNA-seq data (GSE98622) and further c
