New research shows that the male X chromosome is silenced in some types of cancer. Researchers evaluated how a certain gene affects the male X chromosome in cancer cells. Experts explain why these new ...

New progress has been made on the road to understanding the origins of genetic changes in tumor cells. The prevalent theory has been that genetic changes in tumor cells come about in multiple stages ...
