Possible effects of melatonin and omega-3 on the obesity-related hypothalamic nuclei of the electromagnetic field-exposed offspring rats: a stereological and immunohistochemical analysis.
This animal study examined whether prenatal exposure to a 900 MHz electromagnetic field affects obesity-related hypothalamic nuclei in male rat offspring and whether melatonin or omega-3 modifies these effects. The EMF-exposed group showed fewer neurons in the arcuate nucleus, stronger NPY immunoreactivity, and behavioral differences on open field and elevated plus maze tests compared with controls. The authors conclude prenatal mobile-phone-like exposure may induce hypothalamic neurodegeneration and affect obesity-related markers, while melatonin and omega-3 effects were not apparent.
Key points
- Pregnant rats were exposed to 900 MHz EMF for 2 hours per day throughout pregnancy.
- Offspring in the EMF group had a significantly lower neuron number in the arcuate nucleus compared with the sham group.
- Behavioral testing indicated differences in the EMF group versus control in open field and elevated plus maze measures.
- Stronger anti-NPY immunoreactivity was reported in the EMF group.
- Oxidative stress markers differed across groups, including higher SOD activity in the omega-3 group and higher catalase activity in the EMF group versus some comparators.
- The abstract states that melatonin and omega-3 did not show apparent therapeutic effects against EMF-related changes.
