AI Decodes Hidden 'Initiator' Sequence in Human DNA Healthy cell function depends on genes turning on at the precise time and location. Researchers at UC San Diego have used machine learning to decode the "initiator"—a fundamental DNA sequence element that marks where gene expression begins. By searching human genomic data with the AI model, the team discovered that this activation code is present in roughly 60% of human genes. Predicting Disease Mutations and Designing Synthetic DNA To train the model, researchers measured gene expression across 500,000 synthetic initiator variants. Decoding this signature allows scientists to predict how specific mutations alter gene expression to trigger cellular malfunctions and diseases such as cancer. Furthermore, the findings provide a blueprint for engineering synthetic promoters with custom gene-activation functions. Mapping the Human Gene Expression Code This study represents a significant step toward decoding the full multi-billion-base gene expression code governing human biology. Combining high-throughput laboratory experiments with predictive AI models bridges a major gap between raw genomic sequencing and functional molecular biology, advancing the future of personalized medicine. https://lnkd.in/evK6bzKW
