PPM1D Mutations Silence NAPRT Gene Expression and Confer NAMPT Inhibitor Sensitivity in Glioma

Genome wide DNA methylation profiling of wild type and PPM1D mutant astrocytes and patient-derived DIPG cell lines. The Illumina Human EPIC Bead Array (850k) platform was used to obtain methylation beta values of over 850k CpG sites throughout the genome across a panel of DIPG cell lines. 50-500ng of genomic DNA was bisulfite-converted and analyzed for genome-wide methylation patterns using the Illumina Human EPIC Bead Array (850k) platform at the Yale Center for Genome Analysis (Astrocyte and SU-DIPG lines) or University College London Genomics Centre (HSJD DIPG lines), according the manufacturer’s instructions.
