California teen finds blocking one pathway stops cancer cells from spreading
Jonathan Yan, an 18-year-old student from California, studied data from 479 human cancer cell lines to understand how cancer spreads. His research found that the transsulfuration pathway was highly active in metastatic cancers. When he blocked the pathway in cancer cell lines, the cells stopped spreading, pointing to a possible area for further research into cancer metastasis.
Jonathan Yan, an 18-year-old student from Irvine, California, has discovered a way to prevent cancer cells from spreading by blocking a specific pathway within the cells. As part of his computational biology and bioinformatics project for the 2026 Regeneron Science Talent Search, Yan examined data from 479 human cancer cell lines, focusing on the process of metastasis - the spread of cancer cells to other organs.
Metastatic cancers, which have formed secondary tumors in different parts of the body, are notoriously difficult to treat. Yan's research identified a biological process called the transsulfuration pathway that was highly active in these metastatic cells. By blocking this pathway in cancer cell lines, Yan successfully halted the cells' ability to spread.
The transsulfuration pathway is involved in the processing of amino acids, the building blocks of proteins, and in the production of antioxidants that protect cells from damage. Yan's groundbreaking work could lead to new strategies for preventing the spread of cancer cells, potentially improving treatment outcomes for patients with metastatic cancer.
