***CASE REPORT*** Gliosarcoma after diagnosis of fibrillary astrocytoma

Conversion of a Gemistocytic Astrocytoma to a Fibrillary Astrocytoma after Temozolomide and Radiation Therapy

In most instances, gemistocytic astrocytoma progresses to anaplastic astrocytoma at the time of recurrence. Here, we report an unusual case where a gemistocytic astrocytoma converted to a more benign fibrillary histology after temozolomide/radiation therapy. We present the case of a 26-year-old woman with a history of fibrillary astrocytoma that was followed over a span of eight years and under...

Cerebral astrocytoma in a sheep

Astrocytoma as one of the most common central nervous system (CNS) tumors is rarely reported in veterinary literature.

Acidic Protein Complementary DNA: Analysis of Expression, Transfection of Human Astrocytoma Cells with Glial Fibrillary

Glial fibrillary acidic protein (GFAP) is a A/, 50,000 intracytoplasmic filamentous protein that constitutes a portion of, and is spécifiefor the cytoskeleton of the astrocyte. GFAP appears to stabilize the astrocyte's cytoskeleton, and helps maintain normal astrocyte cell shape through complex interactions between it and the nuclear and plasma membranes. A critical observation from histopatho...
