Random DNA mix-ups not so random in cancer development

Researchers have pinpointed a mechanism that may help explain how chromosomal translocations -- the supposedly random shuffling of large chunks of DNA that frequently lead to cancer -- aren't so random after all. They have developed a model of such chromosomal mix-ups in prostate cancer which indicates that the male sex hormone (androgen) receptor unexpectedly plays a key role in driving specific translocations in the development of cancer.
