Cell Phone Radiation of Effects on Cancer Risk

Several studies demonstrate strong links between electromagnetic wave radiation exposure and adversehealth effects. Given the functional importance of the hippocampus, this study aimed to investigate theeffects of electromagnetic waves radiated by mobile phones on hippocampal expression of P21 and P53genes as regulators of cellular apoptosis. Forty-eight male BALB/c mice were randomly divided into sixgroups (n=8 each). Animals in the four experimental groups were respectively exposed for 30 minutes,one, two and four hours to electromagnetic waves radiated twice a day at the frequencies of 900 and 1800megahertz for a period of 30 consecutive days. One of experimental group was radiated for 4 hours oncea day, while the control group remains constant during the experiment. The hippocampal expression ofP21and P53 mRNAs were evaluated using Real-Time PCR.The ratio expression of P53 and P21 geneswas increased to greater than one (P53/P21> 1) in allexperimental groups compared to controls, except forthe group with 2 hours twice a day exposure. However, there was not significant differences between theexpression level of P53 and P21 genes among the experimental groups using paired t test (p> 0.05).In fact, radio frequencies of mobile phones damage brain cells depending on the duration of theconversation (the duration of radiation). While further investigation is recommended, our results revealedthat the mobile phone radiation had no effect on the hippocampus expression of P53 and P21 genes in themice.
