Microwave induced alteration in the neuron specific enolase gene expression
Cancer Biochemistry Biophysics
|September 1, 1993
Summary
Electromagnetic radiation exposure increased neuron specific enolase (NSE), a cancer marker, in cells. Researchers also observed changes in non-neuronal enolase (NNE) expression, suggesting potential clinical applications.
Area of Science:
- Biochemistry
- Cell Biology
- Oncology
Background:
- Neuron specific enolase (NSE) is a biomarker for neurological disorders and cancers.
- Cellular responses to electromagnetic radiation (EMR) are not fully understood.
- Understanding EMR effects on gene expression is crucial for safety and clinical applications.
Purpose of the Study:
- To investigate the effect of specific electromagnetic radiation parameters on neuron specific enolase (NSE) and non-neuronal enolase (NNE) expression.
- To analyze alterations in NSE and NNE activity following EMR exposure.
- To discuss potential clinical implications of these findings.
Main Methods:
- Exposure of pNGE7 cells (expressing neuron specific enolase gene) to 915 MHz, 16 Hz Amplitude Modulated EMR at a SAR of 0.05 mW/kg.
- Separation of NSE and NNE activities using ion-exchange chromatography.
- Quantification of NSE and NNE expression levels.
Main Results:
- EMR exposure led to a significant elevation in neuron specific enolase (NSE) levels.
- Alterations in the expression of both neuron specific enolase (NSE) and non-neuronal enolase (NNE) were observed.
- Ion-exchange chromatography successfully differentiated NSE and NNE activities.
Conclusions:
- Electromagnetic radiation can modulate the expression of neuron specific enolase and non-neuronal enolase.
- The observed changes in NSE and NNE suggest potential roles in cancer diagnostics or treatment.
- Further research is warranted to explore the clinical applications of these findings.
