This article previews a mechanistic research study examining how loss of a key R-loop regulator in podocytes links nuclear RNA:DNA hybrid dysregulation to innate inflammatory signaling in diabetic kidney disease.
Key Takeaways
- Single-cell analysis identified selective collapse of the R-loop regulatory network in diabetic podocytes
- SSB was pinpointed as a dominant podocyte R-loop resolver and showed strong diagnostic performance (AUC = 0.983)
- SSB loss caused R-loop accumulation that activated cGAS inflammation, reversible by RNase H1 or cGAS depletion
