A new study shows that a gene involved in pancreatic cancer may also play a role in melanoma. The researchers found that when mice lack a gene called PDK1, their melanomas are smaller and less likely to spread. These mice also live longer. Likewise, when mice that have this gene are treated with a PDK1 inhibitor, melanomas are slower to form and hardly ever spread. If this gene is also linked to melanoma in people, it could provide a new target for treating this cancer.
