The effects of 50 Hz magnetic field exposure on DNA damage and cellular functions in various neurogenic cells.
Published in: J Radiat Res 2017; 58 (4): 474-486
Aim of study (acc. to author)
- cell viability/cell division/proliferation: cell viability (directly, 24 h and 48 h after exposure; spectrophotometry), cell proliferation (directly, 24 h and 48 h after exposure; cell count with hemocytometer), cell cycle distribution (directly, 6 h and 24 h after exposure; propidium iodide stain, flow cytometry); only cortical neurons: neuron morphology (immunofluorescence stain of tau protein (after 2 days exposure; marker for axons), MAP2 (after 6 days exposure; marker for dendrites), PSD95 and gephyrin (after 13 days exposure; markers for excitatory and inhibitory synapses, respectively); fluorescence microscopy)
- genotoxicity/mutation: DNA double strand breaks (directly after exposure; immunofluorescence stain of gamma-H2AX foci, fluorescence microscopy)
- cell function: only astrocytes and microglia: cytokine release (directly after exposure; levels of TNF-α, IL-6 and IL-1β in culture medium, ELISA), only microglia: phagocytosis (fluorescent microspheres uptake, fluorescence microscopy)
Time of investigation:
- during exposure
- after exposure
