Abstract:
Due to their location, the malignant gliomas of the brain in humans are very difficult to treat in advanced stages. Blood-based biomarkers for glioma are needed for more accurate evaluation of treatment response as well as early diagnosis. However, biomarker research in primary brain tumors is challenging given their relative rarity and genetic diversity. It is further complicated by variations in the permeability of the blood brain barrier that affects the amount of marker released into the bloodstream. Inspired by recent temporal data indicating a possible decrease in serum glucose levels in patients with gliomas yet to be diagnosed, we present an ordinary differential equation model to capture early stage glioma growth. The model contains glioma-glucose-immune interactions and poses a potential mechanism by which this glucose drop can be explained. We present numerical simulations, parameter sensitivity analysis, linear stability analysis and a numerical experiment whereby we show how a dormant glioma can become malignant.

Project description:Diffuse midline gliomas (DMGs) are uniformly fatal pediatric central nervous system cancers, refractory to standard of care therapeutic modalities. The primary genetic drivers are a set of recurrent amino acid substitutions in genes encoding histone H3 (H3.3 and H3.1, K27M), which are currently undruggable. These H3K27M oncohistones perturb normal chromatin architecture, resulting in an aberrant epigenetic landscape, which we interrogated here for epigenetic dependencies using a CRISPR screen in patient-derived H3K27M-glioma neurospheres. We show that H3K27M-glioma cells are dependent on core components of the mammalian SWI/SNF (BAF) chromatin remodeling complex for maintaining glioma stem cells in a cycling, oligodendrocyte precursor cell (OPC)-like state. Genetic perturbation of the BAF catalytic subunit SMARCA4 (BRG1), as well as pharmacological suppression opposes proliferation, promotes differentiation, and improves overall survival of patient-derived xenograft (PDX) models. In summary, we demonstrate that therapeutic inhibition of BAF complex has translational potential for children with H3K27M-gliomas.
