Epub 2014 May 9. PMID: 24813634 Abstract Title:  The protective effect of autophagy on mouse spermatocyte derived cells exposure to 1800MHz radiofrequency electromagnetic radiation. Abstract:  The increasing exposure to radiofrequency (RF) radiation emitted from mobile phone use has raised public concern regarding the biological effects of RF exposure on the male reproductive system. Autophagy contributes to maintaining intracellular homeostasis under environmental stress. To clarify whether RF exposure could induce autophagy in the spermatocyte, mouse spermatocyte-derived cells (GC-2) were exposed to 1800MHz Global System for Mobile Communication (GSM) signals in GSM-Talk mode at specific absorption rate (SAR) values of 1w/kg, 2w/kg or 4w/kg for 24h, respectively. The results indicated that the expression of LC3-II increased in a dose- and time-dependent manner with RF exposure, and showed a significant change at the SAR value of 4w/kg. The autophagosome formation and the occurrence of autophagy were further confirmed by GFP-LC3 transient transfection assay and transmission electron microscopy (TEM) analysis. Furthermore, the conversion of LC3-I to LC3-II was enhanced by co-treatment with Chloroquine (CQ), indicating autophagic flux could be enhanced by RF exposure. Intracellular ROS levels significantly increased in a dose- and time-dependent manner after cells were exposed to RF. Pretreatment with anti-oxidative NAC obviously decreased the conversion of LC3-I to LC3-II and attenuated the degradation of p62 induced by RF exposure. Meanwhile, phosphorylated extracellular-signal-regulated kinase (ERK) significantly increased after RF exposure at the SAR value of 2w/kg and 4w/kg. Moreover, we observed that RF exposure did not increase the percentage of apoptotic cells, but inhibition of autophagy could increase the percentage of apoptotic cells. These findings suggested that autophagy flux could be enhanced by 1800MHz GSM exposure (4w/kg), which is mediated by ROS generation. Autophagy may play an important role in preventing cells from apoptotic cell death under RF exposure stress. <p><a href="https://greenmedinfo.com/article/1800-mhz-increases-oxidative-stress-and-apoptosis-mouse-derived-sperm-cells-n-" target="_blank">read more</a></p> https://greenmedinfo.com/article/1800-mhz-increases-oxidative-stress-and-apoptosis-mouse-derived-sperm-cells-n-#comments Infertility Infertility: Male NAC (N-acetyl-L-cysteine) Oxidative Stress Radiation Induced Illness Sperm Count: Low Sperm Quality: Low Antioxidant Apoptotic Cell Phone Exposure Electromagnetic Field Harms Electromagnetic Radiation Electromagnetic Radiation: 1.8 GHz Microwave Radiation Mobile Phone Radiation Oxidant Autophagy Autophagy Up-regulation Cell Phones electromagnetic fields electromagnetic frequencies electromagnetic radiation EMF infertility male infertility Male Infertility and Cellular Phones Radio Frequency Electromagnetic Radiation Exposure In Vitro Study Fri, 02 Aug 2019 20:17:48 +0000 greenmedinfo 192634 at https://greenmedinfo.com 1800 MHz radiofrequency fields stimulates pro-inflammatory responses in microglia and astrocytes in vitro. https://greenmedinfo.com/article/1800-mhz-radiofrequency-fields-stimulates-pro-inflammatory-responses-microglia PMID:  PLoS One. 2014 ;9(9):e108318. Epub 2014 Oct 2. PMID: 25275372 Abstract Title:  Differential pro-inflammatory responses of astrocytes and microglia involve STAT3 activation in response to 1800 MHz radiofrequency fields. Abstract:  Microglia and astrocytes play important role in maintaining the homeostasis of central nervous system (CNS). Several CNS impacts have been postulated to be associated with radiofrequency (RF) electromagnetic fields exposure. Given the important role of inflammation in neural physiopathologic processes, we investigated the pro-inflammatory responses of microglia and astrocytes and the involved mechanism in response to RF fields. Microglial N9 and astroglial C8-D1A cells were exposed to 1800 MHz RF for different time with or without pretreatment with STAT3 inhibitor. Microglia and astrocytes were activated by RF exposure indicated by up-regulated CD11b and glial fibrillary acidic protein (GFAP). However, RF exposure induced differential pro-inflammatory responses in astrocytes and microglia, characterized by different expression and release profiles of IL-1β, TNF-α, IL-6, PGE2, nitric oxide (NO), inducible nitric oxide synthase (iNOS) and cyclooxygenase 2 (COX2). Moreover, the RF exposure activated STAT3 in microglia but not in astrocytes. Furthermore, the STAT3 inhibitor Stattic ameliorated the RF-induced release of pro-inflammatory cytokines in microglia but not in astrocytes. Our results demonstrated that RF exposure differentially induced pro-inflammatory responses in microglia and astrocytes, which involved differential activation of STAT3 in microglia and astrocytes. Our data provide novel insights into the potential mechanisms of the reported CNS impacts associated with mobile phone use and present STAT3 as a promising target to protect humans against increasing RF exposure. <p><a href="https://greenmedinfo.com/article/1800-mhz-radiofrequency-fields-stimulates-pro-inflammatory-responses-microglia" target="_blank">read more</a></p> https://greenmedinfo.com/article/1800-mhz-radiofrequency-fields-stimulates-pro-inflammatory-responses-microglia#comments Brain: Microglial Activation Inflammation Cell Phone Exposure Cycloogenase-2 enzyme upregulation Electromagnetic Field Harms Electromagnetic Radiation Electromagnetic Radiation: 1.8 GHz Inflammatory Interleukin-1 up-regulation Interleukin-6 up-regulation Microwave Radiation Mobile Phone Radiation Prostaglandin E2 up-regulation Tumor necrosis factorα (TNFα) up-regulation Brain Function Brain Inflammation Cell Phones electromagnetic fields electromagnetic frequencies electromagnetic radiation EMF Human In Vitro Fri, 02 Aug 2019 22:52:09 +0000 greenmedinfo 192680 at https://greenmedinfo.com 1800 MHz radiofrequency radiation impairs neurite outgrowth of embryonic neural stem cells which are essential for embryonic brain development. https://greenmedinfo.com/article/1800-mhz-radiofrequency-radiation-impairs-neurite-outgrowth-embryonic-neural-s PMID:  Sci Rep. 2014 May 29 ;4:5103. Epub 2014 May 29. PMID: 24869783 Abstract Title:  Exposure to 1800 MHz radiofrequency radiation impairs neurite outgrowth of embryonic neural stem cells. Abstract:  A radiofrequency electromagnetic field (RF-EMF) of 1800 MHz is widely used in mobile communications. However, the effects of RF-EMFs on cell biology are unclear. Embryonic neural stem cells (eNSCs) play a critical role in brain development. Thus, detecting the effects of RF-EMF on eNSCs is important for exploring the effects of RF-EMF on brain development. Here, we exposed eNSCs to 1800 MHz RF-EMF at specific absorption rate (SAR) values of 1, 2, and 4 W/kg for 1, 2, and 3 days. We found that 1800 MHz RF-EMF exposure did not influence eNSC apoptosis, proliferation, cell cycle or the mRNA expressions of related genes. RF-EMF exposure also did not alter the ratio of eNSC differentiated neurons and astrocytes. However, neurite outgrowth of eNSC differentiated neurons was inhibited after 4 W/kg RF-EMF exposure for 3 days. Additionally, the mRNA and protein expression of the proneural genes Ngn1 and NeuroD, which are crucial for neuriteoutgrowth, were decreased after RF-EMF exposure. The expression of their inhibitor Hes1 was upregulated by RF-EMF exposure. These results together suggested that 1800 MHz RF-EMF exposure impairs neurite outgrowth of eNSCs. More attention should be given to the potential adverse effects of RF-EMFexposure on brain development. <p><a href="https://greenmedinfo.com/article/1800-mhz-radiofrequency-radiation-impairs-neurite-outgrowth-embryonic-neural-s" target="_blank">read more</a></p> https://greenmedinfo.com/article/1800-mhz-radiofrequency-radiation-impairs-neurite-outgrowth-embryonic-neural-s#comments Cell Phone Exposure Electromagnetic Field Harms Electromagnetic Radiation Electromagnetic Radiation: 1.8 GHz Microwave Radiation Mobile Phone Radiation Neurotoxic Cell Phones electromagnetic fields electromagnetic frequencies electromagnetic radiation EMF Pregnancy Pregnancy And Fetal Growth Radio Frequency Electromagnetic Radiation Exposure Human In Vitro Fri, 02 Aug 2019 22:58:51 +0000 greenmedinfo 192686 at https://greenmedinfo.com 1800 MHz RF-EMF fields result in cell type-dependent DNA damage and a significant increase in reactive oxygen species level, however researchers conclude it doesn't contribute to cell dysfunction. https://greenmedinfo.com/article/1800-mhz-rf-emf-fields-result-cell-type-dependent-dna-damage-and-significant-i PMID:  PLoS One. 2013 ;8(1):e54906. Epub 2013 Jan 23. PMID: 23355902 Abstract Title:  Cell type-dependent induction of DNA damage by 1800 MHz radiofrequency electromagnetic fields does not result in significant cellular dysfunctions. Abstract:  BACKGROUND: Although IARC clarifies radiofrequency electromagnetic fields (RF-EMF) as possible human carcinogen, the debate on its health impact continues due to the inconsistent results. Genotoxic effect has been considered as a golden standard to determine if an environmental factor is a carcinogen, but the currently available data for RF-EMF remain controversial. As an environmental stimulus, the effect of RF-EMF on cellular DNA may be subtle. Therefore, more sensitive method and systematic research strategy are warranted to evaluate its genotoxicity.OBJECTIVES: To determine whether RF-EMF does induce DNA damage and if the effect is cell-type dependent by adopting a more sensitive methodγH2AX foci formation; and to investigate the biological consequences if RF-EMF does increase γH2AX foci formation.METHODS: Six different types of cells were intermittently exposed to GSM 1800 MHz RF-EMF at a specific absorption rate of 3.0 W/kg for 1 h or 24 h, then subjected to immunostaining with anti-γH2AX antibody. The biological consequences in γH2AX-elevated cell type were further explored with comet and TUNEL assays, flow cytometry, and cell growth assay.RESULTS: Exposure to RF-EMF for 24 h significantly inducedγH2AX foci formation in Chinese hamster lung cells and Human skin fibroblasts (HSFs), but not the other cells. However, RF-EMF-elevated γH2AX foci formation in HSF cells did not result in detectable DNA fragmentation, sustainable cell cycle arrest, cell proliferation or viability change. RF-EMF exposure slightly but not significantly increased the cellular ROS level.CONCLUSIONS: RF-EMF induces DNA damage in a cell type-dependent manner, but the elevatedγH2AX foci formation in HSF cells does not result in significant cellular dysfunctions. <p><a href="https://greenmedinfo.com/article/1800-mhz-rf-emf-fields-result-cell-type-dependent-dna-damage-and-significant-i" target="_blank">read more</a></p> https://greenmedinfo.com/article/1800-mhz-rf-emf-fields-result-cell-type-dependent-dna-damage-and-significant-i#comments DNA damage Oxidative Stress Cytotoxic Electromagnetic Field Harms Electromagnetic Radiation Electromagnetic Radiation: 1.8 GHz Genotoxic Microwave Radiation Mobile Phone Radiation Oxidant Cell Phones electromagnetic fields electromagnetic frequencies electromagnetic radiation EMF In Vitro Study Fri, 02 Aug 2019 22:15:17 +0000 greenmedinfo 192667 at https://greenmedinfo.com 2.1 GHz microwave radiation decreases cell viability, reduces mitochondrial membrane potential, and results in cell death in breast fibroblast cells in vitro. https://greenmedinfo.com/article/21-ghz-microwave-radiation-decreases-cell-viability-reduces-mitochondrial-memb PMID:  Cell Biochem Biophys. 2013 ;67(3):1371-8.

Abstract:  In the present study we aimed to investigate the effects of 2.1 GHz Wideband Code Division Multiple Access (W-CDMA) modulated Microwave (MW) Radiation on cell survival and apoptotic activity of human breast fibroblast cells. The cell cultures were exposed to W-CDMA modulated MW at 2.1 GHz at a SAR level of 0.607 W/kg for 4 and 24 h. The cell viability was assessed by MTT [3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] method. The percentage of apoptotic cells was analyzed by Annexin V-FITC and PI staining. 5,5&#039;,6,6&#039;-Tetrachloro-1,1&#039;,3,3&#039;- tetraethylbenzimidazolcarbocyanine iodide (JC-1) was used to measure Mitochondrial Membrane Potential (ΔΨm). sFasL and Fas/APO-1 protein levels were determined by ELISA method. 2.1 GHz MW radiation was shown to be able to inhibit cell proliferation and induce apoptosis in human breast fibroblast cells. The cell viability of MW-exposed cells was decreased significantly. The percentages of Annexin V-FITC positive cells were higher in MW groups. ΔΨm was decreased significantly due to MW radiation exposure. However, neither sFas nor FasL level was significantly changed in MW-exposed fibroblast cells. The results of this study showed that 2.1 GHz W-CDMA modulated MW radiation-induced apoptotic cell death via the mitochondrial pathway. <p><a href="https://greenmedinfo.com/article/21-ghz-microwave-radiation-decreases-cell-viability-reduces-mitochondrial-memb" target="_blank">read more</a></p> https://greenmedinfo.com/article/21-ghz-microwave-radiation-decreases-cell-viability-reduces-mitochondrial-memb#comments Mitochondrial Dysfunction Apoptotic Cytotoxic Electromagnetic Field Harms Electromagnetic Radiation Electromagnetic Radiation: 2.4 GHz Microwave Radiation electromagnetic fields electromagnetic frequencies electromagnetic radiation EMF Human In Vitro Fri, 02 Aug 2019 01:02:00 +0000 greenmedinfo 192588 at https://greenmedinfo.com 2.4 GHz electromagnetic field exposure increases DNA oxidation in brain and plasma and plasma protein oxidation in rats.

PMID: 24844368 Abstract Title:  Increased DNA oxidation (8-OHdG) and protein oxidation (AOPP) by low level electromagnetic field (2.45 GHz) in rat brain and protective effect of garlic. Abstract:  PURPOSE: To investigate the oxidative damage and protective effect of garlic on rats exposed to low level of electromagnetic fields (EMF) at 2.45 GHz Microwave radiation (MWR).METHODS: Thirty-six Wistar rats were divided into three groups. Group I was the control group and not exposed to EMF. Group II and III were exposed to low level EMF (3.68± 0.36 V/m) at 2.45 GHz MWR for 1 hour/day for 30 consecutive days. Daily 500 mg/kg garlic was given to Group III during the study period. At the end of the study, thiobarbituric acid reactive substances (TBARS), advanced oxidation protein products (AOPP) and 8-hydroxydeoxyguanosine (8-OHdG) levelswere investigated in brain tissue and blood samples.RESULTS: Exposure to low level of EMF increased 8-OHdG level in both plasma and brain tissue whereas it increased AOPP level only in plasma. Garlic prevented the increase of 8-OHdG level in brain tissue and plasma AOPP levels.CONCLUSIONS: It may be concluded that low level EMF at 2.45 GHz MWR increases the DNA damage in both brain tissues and plasma of the rats whereas it increases protein oxidation only in plasma. It may also be argued that the use of garlic decreases these effects. <p><a href="https://greenmedinfo.com/article/24-ghz-electromagnetic-field-exposure-increases-dna-oxidation-brain-and-plasma" target="_blank">read more</a></p> https://greenmedinfo.com/article/24-ghz-electromagnetic-field-exposure-increases-dna-oxidation-brain-and-plasma#comments DNA damage Garlic Oxidative Stress Antioxidant Electromagnetic Field Harms Electromagnetic Radiation Electromagnetic Radiation: 2.4 GHz Genoprotective Genotoxic Microwave Radiation Mobile Phone Radiation Oxidant Radioprotective Cell Phones electromagnetic fields electromagnetic frequencies electromagnetic radiation EMF Plant Extracts Radio Frequency Electromagnetic Radiation Exposure Animal Study Fri, 02 Aug 2019 23:38:27 +0000 greenmedinfo 192711 at https://greenmedinfo.com 2.45 GHz exposure leads to morphological changes in rat thyroid, which may indicate a glandular response to acute or repeated stress from radiation in the hypothalamic-pituitary-thyroid axis. https://greenmedinfo.com/article/245-ghz-exposure-leads-morphological-changes-rat-thyroid-which-may-indicate-gl PMID:  Exp Biol Med (Maywood). 2015 Sep ;240(9):1123-35.

Abstract:  Non-ionizing radiation at 2.45 GHz may modify the morphology and expression of genes that codify heat shock proteins (HSP) in the thyroid gland. Diathermy is the therapeutic application of non-ionizing radiation to humans for its beneficial effects in rheumatological and musculo-skeletal pain processes. We used a diathermy model on laboratory rats subjected to maximum exposure in the left front leg, in order to study the effects of radiation on the nearby thyroid tissue. Fifty-six rats were individually exposed once or repeatedly (10 times in two weeks) for 30 min to 2.45 GHz radiation in a commercial chamber at different non-thermal specific absorption rates (SARs), which were calculated using the finite difference time domain technique. We used immunohistochemistry methods to study the expression of HSP-90 and morphological changes in thyroid gland tissues. Ninety minutes after radiation with the highest SAR,the central and peripheral follicles presented increased size and the thickness of the peripheral septa had decreased. Twenty-four hours after radiation, only peripheral follicles radiated at 12 W were found to be smaller. Peripheral follicles increased in size with repeated exposure at 3 W power. Morphological changes in the thyroid tissue may indicate a glandular response to acute or repeated stress from radiation in the hypothalamic-pituitary-thyroid axis. Further research is needed to determine if the effect of this physical agent over time may cause disease in the human thyroid gland. <p><a href="https://greenmedinfo.com/article/245-ghz-exposure-leads-morphological-changes-rat-thyroid-which-may-indicate-gl" target="_blank">read more</a></p> https://greenmedinfo.com/article/245-ghz-exposure-leads-morphological-changes-rat-thyroid-which-may-indicate-gl#comments Cell Phone Exposure Electromagnetic Field Harms Electromagnetic Radiation Electromagnetic Radiation: 2.4 GHz Microwave Radiation Mobile Phone Radiation electromagnetic fields electromagnetic frequencies electromagnetic radiation EMF Radio Frequency Electromagnetic Radiation Exposure Thyroid Animal Study Fri, 02 Aug 2019 23:29:49 +0000 greenmedinfo 192705 at https://greenmedinfo.com 2450 MHz RF-EMF radiation causes changes in the endothelial permeability and vascularization of the rat thymus. https://greenmedinfo.com/article/2450-mhz-rf-emf-radiation-causes-changes-endothelial-permeability-and-vascular PMID:  Life Sci. 2015 Apr 15 ;127:1-11.

Abstract:  AIMS: Electromagnetic fields (EMFs) can act as inducers or mediators of stress response through the production of heat shock proteins (HSPs) that modulate immune response and thymus functions. In this study, we analyzed cellular stress levels in rat thymus after exposure of the rats to a 2.45 GHz radio frequency (RF) using an experimental diathermic model in a Gigahertz Transverse Electromagnetic (GTEM) chamber.MAIN METHODS: In this experiment, we used H&amp;E staining, the ELISA test and immunohistochemistry to examine Hsp70 and Hsp90 expression in the thymus and glucocorticoid receptors (GR) of 64 female Sprague–Dawley rats exposed individually to 2.45 GHz (at 0, 1.5, 3.0 or 12.0 W power). The 1 g averaged peak and mean SAR values in the thymus and whole body of each rat to ensure that sub-thermal levels of radiation were being reached.KEY FINDINGS: The thymus tissue presented several morphological changes, including increased distribution of blood vessels along with the appearance of red blood cells and hemorrhagic reticuloepithelial cells. Levels of Hsp90 decreased in the thymus when animals were exposed to the highest power level (12 W), but only one group did not show recovery after 24 h. Hsp70 presented no significant modifications in any of the groups. The glucocorticoid receptors presented greater immunomarking on the thymic cortex in exposed animals.SIGNIFICANCE: Our results indicate that non-ionizing sub-thermal radiation causes changes in the endothelial permeability and vascularization of the thymus, and is a tissue-modulating agent for Hsp90 and GR. <p><a href="https://greenmedinfo.com/article/2450-mhz-rf-emf-radiation-causes-changes-endothelial-permeability-and-vascular" target="_blank">read more</a></p> https://greenmedinfo.com/article/2450-mhz-rf-emf-radiation-causes-changes-endothelial-permeability-and-vascular#comments Endothelial Dysfunction Electromagnetic Field Harms Electromagnetic Radiation Electromagnetic Radiation: 2.4 GHz Microwave Radiation Cell Phones electromagnetic fields electromagnetic frequencies electromagnetic radiation EMF heat shock proteins Radio Frequency Electromagnetic Radiation Exposure Animal Study Fri, 02 Aug 2019 23:15:22 +0000 greenmedinfo 192695 at https://greenmedinfo.com 3G cell phone exposure impacts brain function by inducing oxidative stress, DNA fragmentation, and apoptosis through the p38 MAPK pathway. https://greenmedinfo.com/article/3g-cell-phone-exposure-impacts-brain-function-inducing-oxidative-stress-dna-fr PMID:  Cell Biochem Biophys. 2014 Mar ;68(2):347-58.

Abstract:  Cell phone radiation exposure and its biological interaction is the present concern of debate. Present study aimed to investigate the effect of 3G cell phone exposure with computer controlled 2-D stepper motor on 45-day-old male Wistar rat brain. Animals were exposed for 2 h a day for 60 days by using mobile phone with angular movement up to zero to 30°. The variation of the motor is restricted to 90° with respect to the horizontal plane, moving at a pre-determined rate of 2° per minute. Immediately after 60 days of exposure, animals were scarified and numbers of parameters (DNA double-strand break, micronuclei, caspase 3, apoptosis, DNA fragmentation, expression of stress-responsive genes) were performed. Result shows that microwave radiation emitted from 3G mobile phone significantly induced DNA strand breaks in brain.

Over the years multiple studies were published in order to investigate this issue using several approaches. The current study looks at secular trends of brain gliomas (low and high grade) incidence and changes in tumor&#039;s laterality over 30 years in a population extensively using this technology with a possible correlation to the spread of use of mobile phones.MATERIALS AND METHODS: All brain gliomas that were diagnosed from 1980-2009 were included and subdivided into two groups--low and high grade. Secular and periodic time trend analyses of incidence rates and changes in laterality were performed. Preferred side of head using mobile phones was assessed with a questionnaire in a sample of adult individuals.RESULTS: A decrease in incidence of low grade giomas (LGG) that correlated with introduction of mobile technology was found from 2.57, 2.34 and 2.79 for every 100,000 in the period 1980 to the end of 1994 to 1.72, 1.82 and 1.57, respectively, over the last three 5-years periods (1995-2009). High-grade glioma incidences increased significantly from 1980-2009 but in the period after mobile phones were introduced (1994-2009) a lower, non significant, rate of increase was observed in males and a lower one (significant) in females. A shift towards left sided tumor location for all adult gliomas combined and separately for LGG and HGG was noted from 1995 onward. The shift was more marked for those who were diagnosed in ages 20-49 (p=0.03).CONCLUSIONS: We found a statistically significant decrease in LGG&#039;s over 30-years period that correlates with introducing of mobile phones technology and a shift in laterality towards left-sided tumors, the latter occurred in both low and high-grade gliomas. <p><a href="https://greenmedinfo.com/article/shift-towards-left-sided-tumor-location-all-adult-gliomas-was-noted-study-foll" target="_blank">read more</a></p> https://greenmedinfo.com/article/shift-towards-left-sided-tumor-location-all-adult-gliomas-was-noted-study-foll#comments Brain Cancer Glioma Carcinogenic (suspected) Cell Phone Exposure Electromagnetic Field Harms Electromagnetic Radiation Microwave Radiation Mobile Phone Radiation Tumorigenic electromagnetic fields electromagnetic frequencies electromagnetic radiation EMF Radio Frequency Electromagnetic Radiation Exposure Human Study Sat, 03 Aug 2019 16:18:21 +0000 greenmedinfo 192791 at https://greenmedinfo.com According to this animal study, electromagnetic radiation may inhibit autophagy in certain brain regions. https://greenmedinfo.com/article/according-animal-study-electromagnetic-radiation-may-inhibit-autophagy-certain PMID:  Toxicol Ind Health. 2018 Jan ;34(1):23-35.

Abstract:  The exploding popularity of mobile phones and their close proximity to the brain when in use has raised public concern regarding possible adverse effects from exposure to radiofrequency electromagnetic fields (RF-EMF) on the central nervous system. Numerous studies have suggested that RF-EMF emitted by mobile phones can influence neuronal functions in the brain. Currently, there is still very limited information on what biological mechanisms influence neuronal cells of the brain. In the present study, we explored whether autophagy is triggered in the hippocampus or brain stem after RF-EMF exposure. C57BL/6 mice were exposed to 835 MHz RF-EMF with specific absorption rates (SAR) of 4.0 W/kg for 12 weeks; afterward, the hippocampus and brain stem of mice were dissected and analyzed. Quantitative real-time polymerase chain reaction (qRT-PCR) analysis demonstrated that several autophagic genes, which play key roles in autophagy regulation, were significantly upregulated only in the hippocampus and not in the brain stem. Expression levels of LC3B-II protein and p62, crucial autophagic regulatory proteins, were significantly changed only in the hippocampus. In parallel, transmission electron microscopy (TEM) revealed an increase in the number of autophagosomes and autolysosomes in the hippocampal neurons of RF-EMF-exposed mice. The present study revealed that autophagy was induced in the hippocampus, not in the brain stem, in 835 MHz RF-EMF with an SAR of 4.0 W/kg for 12 weeks. These results could suggest that among the various adaptation processes to the RF-EMF exposure environment, autophagic degradation is one possible mechanism in specific brain regions. <p><a href="https://greenmedinfo.com/article/according-animal-study-electromagnetic-radiation-may-inhibit-autophagy-certain" target="_blank">read more</a></p> https://greenmedinfo.com/article/according-animal-study-electromagnetic-radiation-may-inhibit-autophagy-certain#comments Cell Phone Exposure Electromagnetic Field Harms Electromagnetic Radiation Microwave Radiation Mobile Phone Radiation Autophagy Inhibitors Brain Function Cell Phones electromagnetic fields electromagnetic frequencies Electromagnetic Hypersensitivity electromagnetic radiation EMF Radio Frequency Electromagnetic Radiation Exposure Animal Study Sat, 03 Aug 2019 00:53:14 +0000 greenmedinfo 192730 at https://greenmedinfo.com
