# RF-046 — Oxidative mitochondrial DNA markers in primary cortical neurons

Why this matters
Mitochondria supply cells with energy and contain their own DNA. In rat nerve cells grown in the laboratory, the abstract reports changes in that DNA after RF exposure. It identifies a possible dysfunction pathway; incomplete methods and temperature information prevent a conclusion about neurological harm in people.

Topic: Neuronal mitochondrial response

Verification Group: Original abstract verified

Record Role: Original abstract verified

Featured: False

Exposure: 1,800 MHz pulsed RF with 217 Hz modulation,average SAR2 W/kg; primary rat cortical neurons assessed 24 h after exposure.

Design: Primary culture experiment with melatonin pretreatment; full methods, replicate counts and thermometry unverified.

Finding: Original abstract reports increased mitochondrial 8-OHdG and reduced mtDNA copy number/mtRNA transcripts, reversed by melatonin pretreatment.

Boundary: No demonstrated clinical neurotoxicity. Abstract does not establish complete exposure duration or temperature controls. Antioxidant rescue alone does not establish RF specificity.

Related: Chongqing Third Military Medical University programme, linked to Liu 2013 oxidative germ-cell research.

Protection Question: 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.
