Article Abstract
Adriamycin (ADR)-induced nephropathy is frequently utilized in rodent models of podocytopathy. However, the application of this model in mice is limited to a few strains, such as BALB/c mice. The most commonly used mouse strain, C57BL/6 (B6), is resistant to ADR-induced nephropathy, as are all mouse strains with a B6 genetic background. Reportedly, the R2140C variant of the Prkdc gene is the cause of susceptibility to ADR-induced nephropathy in mice. To verify this hypothesis, we produced Prkdc mutant B6 mice, termed B6-Prkdc, that possess the R2140C mutation. After administration of ADR, B6-Prkdc mice exhibited massive proteinuria and glomerular and renal tubular injuries. In addition, there was no significant difference in the severity between B6-Prkdc and BALB/c. These findings demonstrated that B6-Prkdc show ADR-induced nephropathy susceptibility at a similar level to BALB/c, and that the PRKDC R2140C variant causes susceptibility to ADR-induced nephropathy. In future studies, ADR-induced nephropathy may become applicable to various kinds of genetically modified mice with a B6 background by mating with B6-Prkdc.

Parietal epithelial cells (PECs) that line the Bowman's capsule are considered progenitor cells for podocytes, which exhibit limited regeneration capacity following injury. Notch3 receptor has been found to be co-expressed in both podocytes and PECs in focal segmental glomerulosclerosis (FSGS), suggesting a distinct regulatory role in this context. Our previous research indicated that Notch3 signaling is significantly negatively correlated with the cAMP-PKA-CREB-KLF15 pathway in adriamycin (ADR)-injured podocytes.

encodes an actin-binding protein involved in kidney development and has been associated with chronic kidney disease through genome-wide association studies. However, its regulatory role in proteinuric kidney diseases and its mechanistic contributions to podocyte homeostasis remain poorly defined. Here, we analyzed single-cell transcriptomic datasets and the Nephroseq database to delineate expression patterns in proteinuric kidney diseases.
