Weaned Wistar rats were divided into four groups and exposed to EMF (1,760 MHz, 2 h/day) and/or 15% fructose solution for 8 weeks. In the hypothalamic tissue of the combined exposure group, expressions of SIRT1, FOXO1, p-PI3K, p-AKT, Complex III, UCP2, MnSOD, and catalase and activities of OXPHOS and GSH were significantly decreased compared to the normal, EMF-only, and fructose-only groups. In hepatic tissue of the combined exposure group, expressions of p-AMPKα, SIRT1, FOXO1, IRS1, p-PI3K, Complex I, II, III, IV, V, UCP2, and MnSOD and activities of OXPHOS, SOD, catalase, and GSH were significantly reduced compared to the normal group.

Researchers exposed growing rats to mobile phone radiation (1,760 MHz) and high-fructose diets for 8 weeks, finding that the combination significantly disrupted metabolic regulation in the brain and liver. The dual exposure impaired insulin signaling, mitochondrial function, and antioxidant defenses more severely than either stressor alone. This suggests that common modern exposures may work together to increase metabolic dysfunction risk during critical developmental periods.

Researchers exposed two-week-old immature male chickens to non-thermal low-level 2.45 GHz microwave radiation for two hours per day over 30 days. Exposed chickens showed decreased testicular weight, volume, and gonado-somatic index, as well as a substantial reduction in seminiferous tubule diameter. Radiation exposure increased oxidative stress parameters, increased IL-1β immunoreactivity, decreased IL-10 immunoreactivity, and reduced ERα expression in testes.

Researchers exposed young male chickens to WiFi-frequency radiation (2.45 GHz) for 2 hours daily over 30 days and found significant damage to their reproductive systems. The radiation caused testicular shrinkage, increased inflammation, and reduced hormone receptor activity linked to fertility. This study reveals concerning biological mechanisms by which common wireless frequencies may impact male reproductive health.

Researchers exposed young male chickens to 2.45 GHz microwave radiation (the same frequency as WiFi and microwave ovens) for 2 hours daily over 30 days. The radiation caused testicular shrinkage, increased inflammation, and reduced hormone receptor activity linked to male fertility. This study provides biological evidence that common microwave frequencies may impair reproductive development.

Researchers exposed human HEK293 cultured cells to a 1.8 GHz carrier frequency at amplitudes typical of household telecommunications. ROS concentrations increased significantly after 15 minutes of exposure and were localized to both nuclear and cytosolic compartments. qPCR analysis revealed altered gene expression of anti-oxidative enzymes SOD, GPX, and CAT, and oxidative enzyme Nox-2. Multiple genes responsive to static magnetic fields were also regulated by RF, suggesting common response mechanisms. Many RF effects showed evidence of hormesis with biphasic dose-response curves and blind spots at certain amplitudes.

Researchers exposed human cells to 1.8 GHz radiofrequency radiation (similar to cell phone signals) and found it triggered the formation of harmful reactive oxygen species (ROS) within just 15 minutes. The study revealed that cellular damage doesn't increase linearly with signal strength - instead, certain amplitudes caused no measurable effects while others triggered significant responses. This suggests that even everyday wireless exposures can disrupt normal cellular function through oxidative stress.

Rats were exposed to 900 MHz RFR at 2 h/day, 5 days/week for 1 week (acute) or 10 weeks (chronic). The study measured histopathology, PCNA, Bcl-xL, cleaved caspase-3, p-JNK, p-p38, and TUNEL in testis tissue. No histopathological differences or PCNA changes were observed between sham and RFR groups in either period. Cleaved caspase-3 and Bcl-xL showed period-dependent alterations, TUNEL-positive cells increased significantly only after acute exposure, and both p-p38 and p-JNK protein expressions increased significantly in both acute and chronic RFR groups.

Researchers exposed fruit flies to 2.4 GHz WiFi radiation at non-thermal levels and found it caused DNA damage, increased oxidative stress, behavioral changes, and accelerated tumor growth. The study demonstrated that WiFi signals triggered genetic instability by disrupting normal chromosome structure and silencing mechanisms in both brain and reproductive tissues. These findings suggest WiFi radiation may have biological effects beyond heating that warrant further investigation in humans.

Researchers exposed miR-34a-transfected DLD1 colorectal cancer cells to 2.4 GHz RF-EMF for 24 hours and evaluated effects using real-time PCR, scratch assay, and MTS test. Administration of miR-34a decreased expression of per2, bmal1, sirtuin1, and survivin and inhibited proliferation and migration of DLD1 cells. RF-EMF exposure increased cry1 mRNA expression, weakened miR-34a's inhibition of per2, abolished its inhibition of survivin, and eliminated miR-34a's effects on proliferation and migration. The authors concluded that RF-EMF strongly influenced miR-34a-mediated regulation of the peripheral circadian oscillator in DLD1 cells.

Researchers exposed rats to 1800 MHz LTE electromagnetic fields for 2 hours under acute neuroinflammation induced by lipopolysaccharide. The mean specific absorption rate in the auditory cortex was 0.5 W/kg. Exposure reduced neuronal response strength to pure tones and natural vocalizations and increased acoustic thresholds at low and medium frequencies, while microglial coverage did not change. In healthy rats without neuroinflammation, the same exposure did not alter response strength or acoustic thresholds.

The study created four groups (sham, irradiated female, irradiated male, and irradiated male and female) with one male and three females each. The irradiated groups were whole-body exposed to 2450 MHz continuous wave radiofrequency radiation for 12 hours per day across four generations. The researchers examined fetal brain development, histopathological changes in female rats, and hippocampal MAPK protein levels in male rats. In exposed groups, hemorrhagic areas, irregular cellular localization, and vascular structures were observed in the brains of fetal and adult female rats across all generations. In adult male rats, phosphorylated ERK, tau, JNK, and p38 were significantly increased in the brain across all generations.

Turkish researchers exposed rats to WiFi-frequency radiation (2450 MHz) for 12 hours daily across four generations, starting before conception. They found brain hemorrhaging and irregular cell patterns in fetuses and adult females, plus elevated stress proteins linked to memory problems in males. The effects persisted and potentially worsened across generations.

The study used 24 adult male Swiss-Albino mice divided into Four groups of 6. The radiofrequency and adaptive response groups were exposed to a 900 MHz GSM signal at 0.339 W/kg for 4 h/day over 7 days. After the final exposure, bleomycin was injected intraperitoneally at 37.5 mg/kg and the mice were sacrificed 30 minutes later. Oxidative damage and antioxidant mechanisms were examined in blood, DNA-repair gene expression was measured in liver, and apoptosis was assessed in liver using the TUNEL method. The adaptive response group showed increased ROS and p53 and OGG-1 expression, decreased SOD, CAT and TAC levels, and reduced apoptosis.

Researchers continuously exposed pregnant Sprague-Dawley rats and their offspring to 900 MHz GSM-modulated RF-EMR for 24 hours per day and assessed liver oxidative stress at postnatal days 1, 9, and 21. Exposure significantly raised MDA levels at PND9 and PND21, lowered catalase activity at all ages, reduced catalase amount and mRNA at PND1 and PND9, and decreased GPx activity at PND21. CytoSOD levels increased at PND9 and 21 while mitoSOD levels decreased at PND21, and both GPx level and mitoSOD activity were elevated at all ages. SOD1 mRNA expression rose at PND1 but fell at PND9 and 21, whereas GPx1 expression was consistently reduced in the exposed group.

Scientists exposed mice to 900 MHz cell phone radiation for 7 days, then administered a DNA-damaging drug called bleomycin. The RF-exposed mice showed increased DNA repair activity and reduced cell death compared to unexposed mice. This suggests low-level RF exposure may trigger protective cellular responses.

Researchers exposed pregnant and newborn rats to 900 MHz radiofrequency radiation (the same frequency used by many cell phones) 24 hours per day and found significant liver damage in the offspring. The radiation caused oxidative stress, reduced protective antioxidant enzymes, and altered gene expression in the developing liver. This suggests continuous RF exposure during pregnancy and early development may harm liver function in offspring.

Researchers randomly assigned pregnant Sprague-Dawley rats to a control group or a 900-MHz EMF exposure group, with the EMF group exposed daily until birth. Newborn rats were sacrificed by anesthesia on days 7, 10, 15, and 30. Structural damage in cochlear nuclear neurons and oligodendrocytes and increased caspase-3 activity were observed in the EMF groups compared to controls. However, no significant difference was found between groups in structural damage or caspase-3 activity across postnatal stages, and auditory brainstem response latencies did not differ. The authors concluded that prenatal 900-MHz EMF exposure has no harmful effects on ventral cochlear nucleus development.

Eighteen Sprague-Dawley male rats were divided into three groups of six each. Two groups were exposed to 1800 MHz or 2100 MHz microwave radiation for 2 hours per day over 7 months, while a third group served as sham control. After exposure, liver tissue was analyzed for DNA damage, malondialdehyde, 8-hydroxydeoxyguanosine, and total oxidant-antioxidant parameters. Both exposure frequencies significantly increased MDA, 8-OHdG, total oxidant status, oxidative stress index, and comet assay tail intensity, while decreasing total antioxidant status.
