U-M researchers discover gene switched off in cancer can be turned on

...answer, but in principle this tells us we can turn our gene back on. If we can turn the gene back on, it may not be a cure for cancer, but it could slow it down or make it responsive to existing drugs,” Reisman says. The researchers targeted lung cancer cell lines in particular, although they found si...
