Particles resembling oncornaviruses. Spontaneous release from cultured meningioma cells

|February 1, 1977
Abstract:
A cell culture from thoracic cord meningioma tissue obtained at surgery was maintained for several passages in cell culture. These cells spontaneously released particles with an RNA of high-molecular weight (90S to 95S) and a density similar to that of type C oncornaviruses. The implications of these results and similar findings by others are discussed.
Insights
Thoracic cord meningioma cells in culture released particles containing high-molecular weight RNA. These particles resemble type C oncornaviruses, suggesting potential viral involvement in meningiomas.
Area of Science:
- Oncology
- Virology
- Cell Biology
Background:
- Meningiomas are primary tumors of the meninges.
- Investigating the cellular and etiological basis of meningiomas is crucial for understanding tumor development.
Observation:
- A cell culture was established from surgically resected thoracic cord meningioma tissue.
- The meningioma cells were maintained through multiple passages in vitro.
Findings:
- Spontaneous release of virus-like particles was observed from the cultured meningioma cells.
- These particles contained high-molecular weight RNA (90S-95S).
- The particle density was similar to that of type C oncornaviruses.
Implications:
- The findings suggest a potential role for oncornavirus-like agents in meningioma pathogenesis.
- Further research is warranted to explore the viral etiology of meningiomas.
- This study contributes to the understanding of tumor virology and cell culture models.
