The brain could recognizethe cell phone radiation as environmental stress and may alter stress-related gene expression levels. Heat shock proteins (HSP) are a family of proteins that are produced by cells in response to the exposure of stressful conditions. We investigated whether exposure to 1800MHz Radiofrequency Electromagnetic Radiation (RF-EMR) recognize the expression levels of some HSPs (Cryaa, Crybb, Hsp20, Hsp25, Hsp70) in mature rats brain tissue. The experimental group was exposed to 1.800MHz RF-EMR in restrainer for eight weeks with 2 h/day. The specific absorption rate (SAR) was 0.06 W/kg. The sham group was kept in restrainer but not exposed to radiation. The Control group was kept under their condition. Whole brain was homogenized.ViA7 Real-Time-PCR software was used to measure CT values of the genes and ΔΔCT values were also calculated. Cryaa (p=0.02), Crybb (p=0.01), and Hsp20 (p
