A team of researchers at Chiba University in Japan has created a simple cell-based reporter tool to detect epigenetic alterations caused by environmental chemicals. Unlike traditional methods that rely on costly sequencing, this new cost-effective “epi-TK” assay evaluates gene expression changes by tracking methylation and acetylation at a key gene site. Where traditional sequencing techniques often require complex equipment and training, this new test offers a practical way to evaluate the long-term safety of substances used in food, agriculture, and other industries.
