5G-exposed human skin cells do not respond with altered gene expression and methylation profiles [methylation]

ABSTRACT: Due to the ever-increasing wirelessly transmitted data, the development of new transmission standards and higher frequencies in the 5G band is required. Despite basic biophysical considerations that argue against health effects, there is public concern about this technology. Because the skin penetration depth at these frequencies is only 1 millimeter or less, we exposed fibroblasts and keratinocytes to electromagnetic fields up to ten times the permissible limits, for 2 and 48 hours in a fully blinded experimental design. Sham-exposed cells served as negative, and UV-exposed cells as positive controls. Differences in gene expression and methylation due to exposure were small and not higher than expected by chance. These data strongly support the assessment that there is no evidence for exposure-induced damage to human skin cells.

Repeated head-exposures to a 5G-3.5 GHz signal do not alter behavior but modify intracortical gene expression in adult male mice.

Project description:The fifth generation (5G) of mobile communications promotes human exposure to electromagnetic fields exploiting the 3.5 GHz frequency band. We analyzed behaviors, cognitive functions, and gene expression in mice submitted to asymmetrical head exposure to a 5G-modulated 3.5 GHz signal. The exposures were applied for 1 h daily, 5 days per week over a six-week period, at a specific absorption rate (SAR) averaging 0.19 W/kg over the brain. Locomotor activities in an open field, object location, and object recognition memories were assessed repeatedly after four weeks of exposure and did not reveal any significant effect on the locomotion/exploration, anxiety level, or memory processes. mRNA profiling was performed at the end of the exposure period in two symmetrical areas of the right and left cerebral cortex, in which the SAR values were 0.43 and 0.14 W/kg, respectively. We found significant changes in the expression of less than 1% of the expressed genes, with over-representations of genes related to glutamatergic synapses. The right cortical area differed from the left one by an over-representation of responsive genes encoded by the mitochondrial genome. Our data show that repeated head exposures to a 5G-3.5 GHz signal can trigger mild transcriptome alterations without changes in memory capacities or emotional state.

In vivo evaluation of the 94 GHz-chronic exposure effect on Hairless rat skin gene expression [C2]

Project description:Millimeter waves are new broadband frequencies that start to be used in several applications such as future wireless communications, medical, and also non-lethal weapons (the 94-GHz band in Active Denial Systems). However, low information are available on their potential effects on human. These frequencies belong to radiofrequency and they have the property to be stopped by the first layer of the skin. Therefore our studies have aimed to evaluate 94 GHz effects on skin cells whole gene expression. Chronic long term 94 GHz MMW exposures were performed on two rat populations constituted by 17 young animals and 14 adult ones. Each group of animals were equally split in Exposed and Sham exposed subgroup. This two independent exposure experiments were conducted during 5 months, with rats exposed 3 h per day, 3 days per week, to an incident power density of 10 mW/cm², which correspond to twice the ICNIRP limit of exposure for professional. At the end of the experiment, skin explant were taken and RNA were extracted. Then, the modification of the whole gene expression were analyzed with gene expression microarray. Without modification of the animal’s temperature, long term chronic 94 GHz-MMW exposure did not significantly modify the rat’s skin gene expression on both young and adult rats.

Combined effects of EMP and RF exposure on mouse hippocampus LC-MSMS

Project description:Recently, concerns about the combined effects of electromagnetic field (EMF) in daily living and occupational environment are rapidly growing. 4.9 GHz radiofrequency (RF) is commonly used in 5G telecommunication in daily life, EMP is common is occupational environment. Till now, the biological effects of combined exposure to EMP and 4.9 GHz RF have not been fully understood. We used LC-MSMS quantitative proteomics method to investigate the potential effects of EMP and RF field exposure in adult male mice model.

Gene expression profiling of Mycobacterium tuberculosis H37Rv in response to compound CDRI-5g

Project description:Gene expression profiling of Mycobacterium tuberculosis H37Rv in response to compound CDRI-5g (Saquib, M. et al. Eur. J. Med. Chem. 46 (2011) 2217-2223) was studied by administration of compound at 10 µg/ml in broth culture. RNA was extracted at two time points 12 h and 24 h of growth from replicating phase and compound added culture. Replicating phase culture was incubated for the same time and used as a control. Experiment was repeated three times and for each time points triplicate culture was pelleted to isolate total RNA using Qiagen RNA isolation kit.

Gene expression analysis in the zebrafish fractured scale exposed to ELF-EMFs

Project description:The zebrafish scale is a thin membranous bone embedded in the skin and consists of osteoblasts, osteoclasts, and bone matrix, providing an elegant model to understand bone metabolisms. we developed an in vivo model system using zebrafish scales to investigate the effect of extremely low-frequency-electromagnetic fields (ELF-EMFs) on fracture healing. In this study, we have performed RNA-seq analysis on intact scales, fractured scales not exposed to ELF-EMFs, and fractured scales exposed to 10 militesra (mT) of ELF-EMFs.
