Single and Combined Effects of 5ghz Frequency Waves and Computed Tomography(ct) Scan Doses on Whole Blood Parametres, Memory and P53 Gene Expression in Rats

Abstract

BackgroundExponential increase has emerged globally in the use of non‐ionizing and ionizing radio‐frequency electromagnetic fields(Rf‐emfs) for a wide range of applications, daily activities, communication, diagnostics , therapeutics to mention but a few. However, a significant public concern is how these technologies interacts and affects the biota as electromagnetic field (EMF) emissions is linked to dysregulation of genes involved in neurotransmission,oxidative stress and normal cellular function.MethodsStandard methods (y‐maze, novel object recognition tests, automated hematology analyzer, PCR etc), were used to study how the combination of EM waves from 5Ghz radio and CT irradiation affects whole blood parameters, neurobehavioural profiles (memory and cognition), DNA fragmentation and p53 gene expression in Wistar rats which were grouped into five namely: I‐Negative control, II‐sham, III‐5Ghz only , IV‐ 5Ghz+CT, V‐CT only for fourteen days. Genomic DNA was isolated from rats’ cerebral cortex while target gene and internal control primers (GAPDH) were synthesized for p53 gene exons expression and electrophoresed on a 2.5% agarose gel.ResultsWe found that CT irradiation had higher modulatory effects on platelets, white blood cell counts and memory impairments compared to 5GHz only group. However, there was gross DNA damage and complete loss of p53 (exons 5‐7) gene expression profiles in the 5GHz while the CT irradiated rats expressed mutant p53 gene. The effect of CT irradiation in pre‐exposed 5GHz rats revealed mutant p53(exons 5‐7), elevated memory and cognition impairments amongst others .ConclusionDeleterious single effects of 5GHz was observed in p53 gene expression profiles and cognition with an interferential interaction in its combination with CT irradiation leading to mutant p53 gene expression . The impaired neurobehavioural and p53 gene profiles as a result of the single and combined 5GHz and CT exposure predicts functional radiation waves emission effects, changes in resultant protein and dysregulated cellular functions.
