Aim of study (acc. to editor)

To study the effect of mobile phone exposure on the EBV-EA gene expression (EBV-EA gene has been identified as a cancer-related gene).

Background/further details

The cells were divided into four groups (3 flasks per group): group A and group B were not exposed, group C and group D were exposed. Group B and Group D were cultured in TPA (as a tumor promoter) for 48 h before each test.

Time of investigation:
  • during exposure
  • after exposure

Main outcome of study (acc. to author)

The data indicated that mobile phone exposure could induce the expression of EBV-EA in Raji cells and the induction was even more evident with the presence of the tumor promoter TPA.
