The increase in mobile technology has raised concerns about the potential health effects of mobile phone radiation. The biological impact of exposure to radiofrequency (RF) waves emitted by electronic devices has been extensively studied and is a concern for the public, policymakers, and health researchers. The study aimed to examine the impact of 900 MHz radiofrequency waves on biomarkers such as interleukin (IL)-1α, IL-1β, tumour necrosis factor (TNF)-α, homocysteine, nerve growth factor, and serotonin in rats' serum and brain tissue. Thirty adult male Sprague Dawley rats (200 ± 20g) were randomly assigned to three groups (n=10): control (not exposed to RF), exposed I (2 hours per day), and exposed II (4 hours per day). The exposed groups were exposed to 900 MHz RFW for 30 consecutive days. The results showed that only the exposed group II significantly increased serum serotonin levels compared to the control group (P=0.0496). IL-1α, TNF-α, and nerve growth factor levels in brain tissue increased significantly in both exposed groups compared to the control group (P<0.0001). The control group had significantly lower levels of IL-1β compared to exposed groups I (P=0.0289) and II (P=0.0004). Additionally, serotonin and homocysteine levels in the brains of exposed II were significantly higher compared to the other groups (P<0.0001). The results showed disruptions in all biomarkers, indicating the potential impacts of daily exposure to 900 MHz radiofrequency waves from mobile phones on brain function. This suggests that mobile phone radiation may affect brain function.

The aim of this work was to study the, so far, unexplored possibility that non-genetic inheritance of animal behavioral characteristics could depend on the state of the parents at the time of conception, by studying inheritance of high and low motor and exploratory activity in the first generation of rats. In this study, we measured the levels of motor and exploratory activity in rats at the ages of 2 and 5 months. Male and female rats were mated at the age of 5 months. The following groups were used: male and female rats with high motor activity at ages of 2 and 5 months (ACT+); male and female rats with high activity at the age of 2 months, but low activity at the age of 5 months (ACT–); male and female rats with low activity at the ages of 2 and 5 months (PAS–); male and female rats with low activity at the age of 2 months, but high activity at the age of 5 months (PAS+). Significant differences in the severity of exploratory activity were found between the offspring of ACT+ and ACT– rats. Moreover, these differences were observed only in males, and not in females. Differences between the offspring of PAS+ and PAS– rats were observed in both the male and female rats. The motor activity of animals in the period from 20 minutes after the start of registration did not differ between groups. Thus, it can be considered that individual characteristics of general motor activity are due to genetically inherited factors, while differences in the level of exploratory activity, apparently, are formed due to non-genetic influences from parents during mating.

“…In addition to genetic mechanisms of inheritance, various epigenetic factors can also influence the formation of individual behavioral characteristics in offspring. These factors on a pregnant female include physical [ 9 , 10 ], chemical [ 11 , 12 ], and stressful influences [ 13 , 14 ]. Other environmental factors present in the postnatal and adolescent periods have also been reported to affect the formation of behavioral characteristics such as physical [ 15 , 16 ], chemical [ 17 , 18 ], and social influences [ 19 , 20 , 21 ], along with emotional stress [ 22 ].…”

The aim of this work was to study whether epigenetic events at conception influence the formation of behavioral features found in adult rats. First generational inheritance of activity level, anxiety like behavior, and learning ability was studied. To separate genetic and non-genetic inheritance, mating of males and females with average motor activity was carried out in the presence anesthetized or conscious males with high or low activity. Our results show that offspring of parents who mated in the presence of males with a high motor activity were significantly more active than offspring of parents that were paired in the presence of males with low activity. Anxiety like behavior and learning ability were not inherited in this way. It is possible that the phenomenon we discovered is important for maintaining a certain level of activity of specific populations of animals. It counteracts natural selection, which should lead to a constant increase in the activity of animals.
