In our modern environment, humans are constantly exposed to a vast array of pollutants and synthetic chemicals, many of which interact directly with our DNA and cellular processes. These substances can influence how genes are expressed —including important genes like TP53 and BRCA1 —potentially altering critical biological functions without changing the underlying genetic code itself. Over time, these subtle modifications can accumulate, impacting health, development, and even future generations. Scientists have discovered that certain toxins can activate or deactivate genes, a process known as epigenetic regulation , affecting genes such as DNMT1 and MECP2 . Unlike permanent mutations in the DNA sequence, these epigenetic changes are reversible, yet their effects can be profound, influencing not only cellular function but also long-term health outcomes, including disease susceptibility, metabolic regulation, and developmental pathways. Epigenetic alterations provide criti...
