Extremely low-frequency electromagnetic field (ELF-EMF) induced alterations in gene expression and cytokine secretion in clear cell renal carcinoma cells.
This in vitro study exposed three ccRCC cell lines and a healthy kidney cell line (HEK293) to 50 Hz ELF-EMF at 4.5 mT for 30 minutes daily over 5 days. The authors report exposure-associated changes in expression of several genes (names not fully visible in the abstract), with differences between primary tumor-derived lines and a metastatic-model line. Among 30 cytokines/chemokines assessed, only TGF-β1 decreased significantly in HEK293 and CAKI-1 supernatants. The authors emphasize caution in interpreting any potential inhibitory effect on ccRCC progression and call for standardized experimental models.
Key points
- Cells were exposed to 50 Hz ELF-EMF at 4.5 mT for 30 minutes per day for 5 days.
- Gene expression responses differed between primary tumor-derived ccRCC lines and the metastatic-model CAKI-1 line.
- One gene increased after exposure in primary tumor-derived lines, while another gene decreased in 769-P cells.
- Another gene was upregulated in HEK293 and primary tumor lines but not in CAKI-1.
- Of 30 cytokines/chemokines tested, only TGF-β1 showed a significant decrease after exposure in HEK293 and CAKI-1.
- The authors caution against strong conclusions about effects on ccRCC progression and highlight the need for model standardization.
