View Original AbstractRat brain tissue exposed to mobile phone electromagnetic waves showed more p53 and Bcl-2 positive stained cells than controls, suggesting a possible effect on apoptosis.
Plain English Summary
Researchers exposed rats to electromagnetic waves from mobile phones at frequencies between 1900 and 2100 MHz for a four-week period to study effects on apoptosis-related proteins in brain tissue. Immunohistopathological examinations showed that the study group had more p53 and Bcl-2 positive stained cells, and they were stained denser, with statistically significant differences between the study and control groups (p < 0.003). The researchers concluded that electromagnetic waves from mobile phones may have an effect on apoptosis.
Why This Matters
The study included a group of 10 rats exposed to mobile phone electromagnetic waves, a sham group (n=10) that was only immobilized without EMW exposure, and a control group (n=10) with no application. Exposure was designed to simulate daily mobile phone use, with phones attached to rat ears 7 times a day during 5 minutes for a four-week period. Each session consisted of 3 seconds in dialing mode and 4 minutes and 47 seconds in calling mode. The Specific Absorption Rate of the phones ranged between 0.005 W/kg and 0.288 W/kg in dialing mode, and between 0.004 W/kg and 0.029 W/kg in calling mode. For Bcl-2, there was also a statistically significant difference between the study group and the sham group (p < 0.005), but for p53 the difference between those two groups was not statistically significant (p > 0.005). The researchers noted that more realistic application of mobile phones during experiments is more important as expected.

Where This Falls on the Concern Scale
Study Details
Aim of this report was to investigate the effects of the mobile phones on the Bcl-2 gene and p53 proteins in rat brains.

Our results showed that the electro-magnetic waves emitted by the mobile phones may have effect on apoptosis. Besides, obtained data revealed that more realistic application of mobile phones during experiments is more important as expected.
