# RF-047 — Earlier Newcastle male-germline mouse experiment

Why this matters
An earlier Newcastle experiment reported changes in selected DNA targets in exposed mice without changes in sperm function. It helps trace how the later reproductive studies developed. The full methods still need review, and several papers from this group must not be mistaken for several independent laboratory confirmations.

Topic: Reproductive DNA integrity

Verification Group: Original abstract verified

Record Role: Original abstract verified

Featured: False

Exposure: 900 MHz,12 h/day for 7 days; reported whole-body SAR approximately 0.09 W/kg still needs full-method verification.

Design: Mouse exposure; gene-specific quantitative PCR, electrophoresis and sperm-function assays.

Finding: Original abstract reports damage at mitochondrial and nuclear β-globin PCR loci, without gross electrophoresis strand breaks or sperm-function changes.

Boundary: PCR amplification endpoints are not interchangeable with comet/TUNEL or infertility. SAR calculation and thermal controls not rechecked in full.

Related: Foundational Newcastle/Aitken-King programme behind RF-006/007/008; not an independent network.

Protection Question: How do the selected DNA-amplification endpoints relate to later sperm findings? The unchanged sperm function and related research lineage prevent counting this as independent confirmation of reproductive injury.

Access: Original PubMed abstract reviewed. Retrieval lead.

Locator: Abstract.

Notice: No editorial notice surfaced in the Scite/primary-record checks used for this record; this is not a comprehensive clean-bill certification.
