Ependymal astrocytoma: subependyoma or subependymal glomerate astrocytoma [PDF]
Arquivos de Neuro-Psiquiatria, 1982 The histological study of four cases and one by electron microscopy of subependyomomas allowed us to obtain morphostructural characteristics of ependymocytes and astrocytes. Comparing these findings to those of the present day literature, we propose to name these tumours ependymal astrocytomas.

Expression of P53 and Ki-67 in Different Grades of Astrocytomas [PDF]
International Journal of Medical Arts, 2022 Background: Astrocytomas are considered the most prevalent central nervous system [CNS] tumors. Diffuse astrocytomas are evaluated by a three-tiered system [II, III, and IV] according to the 2007 WHO classification. The WHO grading scheme is based on the

Inhibition of STAT3 reduces astrocytoma cell invasion and constitutive activation of STAT3 predicts poor prognosis in human astrocytoma. [PDF]
PLoS ONE, 2013 Astrocytoma cells characteristically possess high invasion potentials. Recent studies have revealed that knockdown of signal transducers and activators of transcription 3 (STAT3) expression by RNAi induces apoptosis in astrocytoma cell. Nevertheless, the

Glutamate Signaling and Filopodiagenesis of Astrocytoma Cells in Brain Cancers: Survey and Questions
Cells, 2022 Astrocytes are non-excitable cells in the CNS that can cause life-threatening astrocytoma tumors when they transform to cancerous cells. Perturbed homeostasis of the neurotransmitter glutamate is associated with astrocytoma tumor onset and progression ...

A 16-gene signature distinguishes anaplastic astrocytoma from glioblastoma. [PDF]
PLoS ONE, 2014 Anaplastic astrocytoma (AA; Grade III) and glioblastoma (GBM; Grade IV) are diffusely infiltrating tumors and are called malignant astrocytomas. The treatment regimen and prognosis are distinctly different between anaplastic astrocytoma and glioblastoma ...
