Application of 23Na MRI at 7 Tesla in distinguishing IDH genotype, P53 phenotype, and Ki‐67 LI in adult‐type diffuse gliomas

VIEW, EarlyView.
Notes: Their molecular characteristics—such as IDH genotype, P53 phenotype, and Ki‐67 labeling index—are critical determinants of treatment strategies and prognosis for patients of adult‐type diffuse gliomas. In this study, we employed 7‐tesla sodium magnetic resonance imaging (23Na MRI) and demonstrated that total sodium concentration (TSC) and ...

Prognostic Roles of Central Carbon Metabolism–Associated Genes in Patients With Low-Grade Glioma

Frontiers in Genetics, 2019
Purpose: Metabolic alterations are crucial for tumor progression and response to therapy. The comprehensive model of combined central carbon metabolism–associated genes that contribute to the outcomes of glioma and astrocytoma is not well understood ...

Trisomy 19 ependymoma, a newly recognized genetico-histological association, including clear cell ependymoma [PDF]

, 2007
Ependymal tumors constitute a clinicopathologically heterogeneous group of brain tumors. They vary in regard to their age at first symptom, localization, morphology and prognosis. Genetic data also suggests heterogeneity.

Meflin/ISLR is a meningeal cell‐specific marker involved in the development of meninges and meningioma progression

Brain Pathology, EarlyView.
Mesenchymal stromal cell‐and fibroblast‐expressing Linx paralogue (Meflin) is expressed in embryonic meninges and contributes to meningeal homeostasis. In meningiomas, elevated Meflin correlates with higher grade and recurrence. Single‐cell RNA sequencing revealed a Meflin‐high tumor cell subset marked by reduced proliferation, WNT6 expression, and ...
