Background

Kidney failure (end-stage renal disease) is one of the leading causes of death not only in patients with kidney disease but also other non-communicable diseases e.g. diabetes, cardiovascular disease, cancer. Nevertheless, effective treatments to halt the progression of kidney failure remain an unmet clinical need worldwide.

Methods

We recently discovered a novel phenomenon "Macrophage-Myofibroblast Transition" (MMT) as a key pro-fibrotic mechanism and ideal therapeutic target to prevent chronic renal failure. By single-cell RNA sequencing and unbiased bioinformatics analysis, we have identified a neural transcription factor as a key regulator of MMT [Tang et al., PNAS 2020]. Here, by using artificial intelligence (AI) drug discovery platform, we successfully identified a novel anti-fibrotic drug “ISO” for targeting the MMT-driven renal failure.

Results

We found that ISO specifically blocks DNA binding of the neural transcription factor at the molecular level, therefore preventing MMT formation on TGF-β1-stimulated macrophages in vitro. More importantly, by conducting macrophage-specific fate mapping with our unique LyzM-tdTomato transgenic mice, we demonstrated that ISO markedly prevents MMT-driven renal fibrosis induced by unilateral ureteral obstruction (UUO) and renal ischemia/reperfusion injury (IRI) without side effects in vivo.

Conclusion

Thus, our AI-guided novel anti-fibrotic drug ISO may represent a safe and effective MMT-targeted therapy for preventing chronic renal failure in clinics.
