Oncogenes and tumor suppressor genes: therapeutic implications
Abstract:
Genetic instability is a hallmark of cancer. Alterations in DNA through mutations, deletions, and translocations affect genes that are fundamental to normal cell growth differentiation and programmed cell death. Here, we discuss these alterations as they relate to oncogenes and tumor suppressor genes. In addition, we describe the implications the changes in oncogenes and tumor suppressor genes have on designing new therapeutic strategies for the treatment of cancer.
