Progression from low- to high-grade astrocytoma is characterized by transcriptomal heterogeneity and genomic number copy alterations (part 2)

(Submitter supplied) We used genetically-engineered mice (GEM) to target constitutive RTK effector pathway (KrasG12D and/or Pten deletion) mutations in G1/S checkpoint-defective adult mouse astrocytes. Genetic lineage tracing showed that these mutations potentiated tumor initiation in cortical, diencephalic, brainstem, and olfactory bulb astrocytes, producing low-grade astrocytomas (LGA). LGA lacked copy number abnormalities (CNA), but showed oncogenic driver- and astrocyte location-specific transcriptome profiles, suggesting that both driver mutations and cellular origin contribute to LGA genomic heterogeneity. more...
