Meningiomas are tumors arising from meninges, the membranes surrounding the brain and the spinal cord. Majority of meningiomas (grade-1) are benign and grow slowly. However, atypical meningiomas (grade-2) exhibit increased cellular abnormalities, and grow at a faster rate than benign meningiomas. Moreover, atypical meningiomas prone to recurrence and show resistance to radiotherapy. Atypical meningiomas show higher 18F-FDG uptake in PET scans. No prior reports are available on investigating metabolic fate of glucose in atypical meningiomas. The goal of this study is to probe the metabolic fate of glucose using NMR based [U-13C]glucose isotopic tracing methods in patient-derived atypical meningioma cells.
