Study demonstrated that PPM1D mutant astrocytes and patient-derived PPM1D mutant diffuse intrinsic pontine glioma lines are particularly sensitive to treatment with NAMPT inhibitors. Mutant PPM1D-induced NAMPT inhibitor sensitivity is driven by hypermethylation of CpG islands throughout the genome and the epigenetic silencing of NAPRT, a key gene involved in NAD biosynthesis. | PPM1D mutations silence NAPRT gene expression and confer NAMPT inhibitor sensitivity in glioma.

No correlation between IDH1/2 mutation status and sensitivity for NAMPT inhibitors was observed. Strikingly, higher methylation of the NAPRT promoter was observed in high-grade versus low-grade chondrosarcomas. In conclusion, this study identified NAMPT as a potential target for treatment of chondrosarcoma | NAD Synthesis Pathway Interference Is a Viable Therapeutic Strategy for Chondrosarcoma.
