  "summary": "This animal study examined whether long-term 2.4 GHz Wi-Fi radiofrequency exposure affects brain miRNA expression and fatty acid composition. Sixteen rats were assigned to sham or exposure, with the exposure group receiving 24 h/day Wi-Fi radiation for one year. The study reports increases in rno-miR-181a-5p, phosphatidylserine, and triacylglycerol in the brain after exposure, and the authors suggest such changes could be relevant to disease risk.",
  "key_points": [
    "Animal experiment with 16 Wistar Albino rats split into sham and exposure groups (n=8 each).",
    "Exposure was 2.4 GHz RFR from a Wi-Fi generator for 24 hours per day over one year.",
    "Outcomes included expression of 10 miRNAs and 19 fatty acid patterns in brain cells.",
    "The study reports increased rno-miR-181a-5p in the brains of exposed rats.",
    "The study reports increased phosphatidylserine (PS) and triacylglycerol (TAG) in the brain after exposure.",
    "The abstract does not report SAR or other quantitative exposure/dosimetry metrics.",
    "Authors frame the findings as potentially relevant to future disease risk from uncontrolled RFR use."
