Title: Analysis of the metabolic profile of humans naturally exposed to RF-EM radiation
Project Description: The world is experiencing exponential growth in communication, especially wireless communication. In recent times, wireless connectivity seems to become a part of daily life for everyone. Recent developments in low-cost, low-power, and miniature devices contribute to a significant rise in radiofrequency-electromagnetic field (RF-EM) radiation exposure in our environment, raising concern over its effect on biological systems. The inconsistent and conflicting research results make it difficult to draw definite conclusions about how RF-EM radiation affects living things. This study identified two micro-environments based on their level of exposure to cellular RF-EM radiation – one with significantly less exposure and another with very high exposure to RF-EM radiation. Emphasis is given to studying the metabolites in the urine samples of humans naturally exposed to these two different microenvironments to understand short-term metabolic dysregulations. The study found that the twenty-nine metabolites were dysregulated. Among them, 19 were downregulated, and 10 were upregulated. In particular, Glyoxylate and dicarboxylate and the TCA cycle metabolism pathway have been perturbed. The results indicated that high RF-EM radiation exposure is linked to oxidative stress. Further, the dysregulated metabolites were validated using the ROC curve analysis.
