Electromagnetic field (50 Hz) enhance metabolic potential and induce adaptive/reprogramming response mediated by the increase of N6-methyladenosine RNA methylation in adipose-derived mesenchymal stem cells in vitro.

Research RF Safe Research Library Jan 1, 2024

This in vitro study exposed adipose-derived mesenchymal stem cells to a 50 Hz electromagnetic field (1.5 mT) for 24 and 48 hours and assessed cellular responses. After 24 hours, the authors report increased N6-methyladenosine RNA methylation, increased expression of multiple stem cell markers, and changes in p21 and…

P53 status, and G2/M cell cycle arrest, are determining factors in cell-death induction mediated by ELF-EMF in glioblastoma.

Research RF Safe Research Library Jan 1, 2023

This in vitro study tested ELF-EMF exposure in U87 and U251 glioblastoma cell lines and assessed apoptosis, cell-cycle distribution, cell size, and mRNA expression of cell-cycle genes. The authors report higher apoptosis induction and increased G2/M arrest in U87 compared with U251, alongside increased U87 cell size…

Impact of ketamine administration on chronic unpredictable stress-induced rat model of depression during extremely low-frequency electromagnetic field exposure: Behavioral, histological and molecular study.

Research RF Safe Research Library Jan 1, 2023

This animal study evaluated ketamine administration combined with extremely low-frequency electromagnetic field (ELF-EMF) exposure in a chronic unpredictable stress (CUS) rat model. The authors report that the combined treatment increased depression-like behavior and neuronal degeneration, reduced GFAP(+) cells in…

Anticancer and antibacterial potentials induced post short-term exposure to electromagnetic field and silver nanoparticles and related pathological and genetic alterations: in vitro study.

Research RF Safe Research Library Jan 1, 2022

This in vitro study evaluated short-term extremely low frequency electromagnetic field (ELF-EMF) exposure and silver nanoparticles (AgNPs), alone and combined, for antibacterial effects and apoptosis induction in MCF-7 breast cancer cells. The authors report time-dependent reductions in bacterial viable counts, with…

Pulsed and Discontinuous Electromagnetic Field Exposure Decreases Temozolomide Resistance in Glioblastoma by Modulating the Expression of O-Methylguanine-DNA Methyltransferase, Cyclin-D1, and p53.

Research RF Safe Research Library Jan 1, 2021

This in vitro study evaluated 50 Hz, 70 G electromagnetic field exposure in combination with temozolomide (TMZ) in T98 and A172 glioblastoma cell lines. The authors report that EMF plus TMZ increased cell death and reduced migration potential compared with controls. They also report increased p53 gene expression and…

Exposure to long-term evolution radiofrequency electromagnetic fields decreases neuroblastoma cell proliferation via Akt/mTOR-mediated cellular senescence.

Research RF Safe Research Library Jan 1, 2021

This in vitro study examined LTE RF-EMF exposure effects on SH-SY5Y neuroblastoma cells. The authors report reduced cell proliferation and a G0/G1 cell-cycle delay after 1760 MHz exposure at 4 W/kg for 4 hr/day over 4 days. They report no marked DNA damage signal (γH2AX) and no apoptosis activation, but increased…

Effect of Rehabilitation with Extremely Low Frequency Electromagnetic Field on Molecular Mechanism of Apoptosis in Post-Stroke Patients.

Research RF Safe Research Library Jan 1, 2020

This study evaluated whether adding extremely low frequency electromagnetic field (ELF-EMF) exposure to a rehabilitation program affects apoptosis-related gene expression in post-stroke patients. Forty-eight patients (3–4 weeks post-incident) were divided into ELF-EMF and non-ELF-EMF groups, with the ELF-EMF group…

Effect of Modified Wuzi Yanzong Pill () on Tip60-Mediated Apoptosis in Testis of Male Rats after Microwave Radiation.

Research RF Safe Research Library Jan 1, 2019

This animal study exposed male rats to a single 15-minute microwave radiation session and assessed testicular apoptosis, histopathology, and related proteins. The radiation group showed increased apoptosis and testicular structural alterations versus controls at multiple time points, while a modified Wuzi Yanzong…

2.45 GHz microwave radiation induced oxidative and nitrosative stress mediated testicular apoptosis: Involvement of a p53 dependent bax-caspase-3 mediated pathway.

Research RF Safe Research Library Jan 1, 2018

This animal study exposed 12-week-old male mice to 2.45 GHz continuous-wave microwave radiation (average power density 0.0248 mW/cm; whole-body SAR 0.0146 W/kg) for 2 hours/day over 15, 30, or 60 days. The authors evaluated testicular histology, testosterone, oxidative/nitrosative stress markers, antioxidant enzymes,…

2.45 GHz Microwave Radiation Impairs Learning and Spatial Memory via Oxidative/Nitrosative Stress Induced p53-Dependent/Independent Hippocampal Apoptosis: Molecular Basis and Underlying Mechanism

Research RF Safe Research Library Jan 1, 2015

This animal study exposed male Swiss mice to 2.45 GHz continuous-wave microwave radiation for 2 hours/day over 15, 30, or 60 days. The authors report increased hippocampal oxidative/nitrosative stress and increased apoptosis in neuronal and nonneuronal hippocampal subfields. They also report duration-dependent…
