RF-046Original abstract verified
Oxidative mitochondrial DNA markers in primary cortical neurons
The reported finding
Original abstract reports increased mitochondrial 8-OHdG and reduced mtDNA copy number/mtRNA transcripts, reversed by melatonin pretreatment.
Reading it carefully
No demonstrated clinical neurotoxicity. Abstract does not establish complete exposure duration or temperature controls. Antioxidant rescue alone does not establish RF specificity.
Inside the study
Exposure conditions
1,800 MHz pulsed RF with 217 Hz modulation,average SAR2 W/kg; primary rat cortical neurons assessed 24 h after exposure.
Design & controls
Primary culture experiment with melatonin pretreatment; full methods, replicate counts and thermometry unverified.
Related research & shared cohorts
Chongqing Third Military Medical University programme, linked to Liu 2013 oxidative germ-cell research.
The protection question raised
Could the mitochondrial changes impair neuronal function? Incomplete exposure and thermal information, and the limits of antioxidant rescue, leave the proposed pathway provisional rather than demonstrated neurological harm.
