Cancer genes found to trigger normal cells into tumors
Researchers at a Houston meeting report discovery of cancer genes that transform normal cells. Weinberg and Wigler identify bladder, colon, and lung cancer genes, suggesting each cancer type may have its own gene. The finding reshapes views on genetics and promises progress in understanding cancer.
Cancer genes may trigger bladder cancer says Weinberg
Weinberg cautions against assuming one gene causes each cancer type but notes up to 50 genetic hot spots can initiate cancer. He explains these growth controlling genes drive normal cell and tissue growth and may be involved in embryo development or adult cell turnover. The bladder cancer gene is a mutation of a hot spot, potentially central to its formation. Wigler warns against claiming a single bladder or colon cancer gene exists, while remaining optimistic that the discovered gene could be common in other tumors and help early diagnosis and targeted therapies.
