Researchers at Skoltech have developed an innovative application of generative artificial intelligence to address a long-standing challenge in genetic research. By leveraging AI, they can now reconstruct missing data on the distances between gene pairs within DNA molecules, a crucial step in understanding the 3D structure of DNA. This breakthrough enables scientists to accurately visualize DNA architecture, which is vital for diagnosing genetic diseases and developing targeted therapies.

The study, published in Scientific Reports, marks the first successful attempt to use AI for filling in incomplete microscopy data. Previously, scientists relied on fragmentary information obtained through fluorescence microscopy—a technique that highlights specific gene sequences with fluorescent tags. However, limitations like repetitive sequences made it impossible to label every gene, resulting in incomplete datasets that hindered comprehensive analysis.

Assistant Professor Kirill Polovnikov from Skoltech explained that knowing the distances between certain genes allows the use of mathematical models to determine the remaining, unmeasured distances. The team demonstrated how generative models, a subset of AI typically used for image and text creation, could efficiently solve this problem—an unconventional but promising approach in chromatin research.

This advancement has significant implications for medicine. A detailed understanding of DNA's 3D structure in healthy versus diseased cells can reveal biomarkers for early diagnosis, suggest new drug targets, and inform gene-editing strategies. The work also opens new pathways for applying AI beyond traditional uses, potentially accelerating discoveries in the field of genetics and molecular biology.

By enhancing the interpretation of fluorescence microscopy data, this technology paves the way for more precise diagnostics and personalized treatments for genetic disorders. It exemplifies how AI can contribute to unraveling the complex physical principles governing chromosome organization, ultimately improving our ability to combat genetic diseases.
