- Abstract
- The aim of this work was to evaluate the effect of stratospheric radiations on neural tumour cells. ADF
human glioblastoma cells were hosted on a stratospheric balloon within the 2002 biological experiment campaign
of the Italian Space Agency. The flight at an average height of 37 km lasted about 24 hrs. Cell morphology,
number and viability, cell cycle and apoptosis, some antioxidant enzymes and proteins involved in cell cycle
regulation, DNA repair and gene expression were studied. Stratospheric radiations caused a significant
decrease in cell number, as well as a block of proliferation, but not apoptosis or necrosis. Radiations also induced
activation and induction of some antioxidant enzymes, increase in DNA repair-related proteins (p53 and
Proliferating Cell Nuclear Antigen) and variations of the transcription factors Peroxisome Proliferator-Activated
Receptors. Morphologically, test cells exhibited more electron dense cytoplasm and less condensed chromatin
than controls and modification of their surfaces. Our results indicate that glioblastoma cells, exposed to
continuous stratospheric radiations for 24 hrs, show activation of cell cycle check point, decrease of cell number,
variations of Peroxisome Proliferator-Activated Receptors and increase of Reactive Oxygen Species-scavenging
enzymes. (literal)
