Oncogene addiction: setting the stage for molecularly.
What does oncogene mean? oncogene is defined by the lexicographers at Oxford Dictionaries as A gene which in certain circumstances can transform a cell into a tumor cell.
An oncogene is a gene that has the potential to cause cancer. Or, equally good, an oncogene is a gene which brings about uncontrolled cell division. Oncogenes in tumor cells are often mutated or expressed at high levels. Most normal cells undergo a programmed form of death ().Activated oncogenes can cause those cells designated for apoptosis to survive and proliferate instead.
Oncogene Definition. In a cell with normal control regulation (non-cancerous), genes produce proteins that provide regulated cell division. Cancer is the disease caused by cells that have lost their ability to control their regulation. The abnormal proteins allowing the non-regulated cancerous state are produced by genes known as oncogenes. The normal gene from which the oncogene evolved is.
Oncogene definition, any gene that is a causative factor in the initiation of cancerous growth. See more.
Cancer epigenetics is the study of epigenetic modifications to the DNA of cancer cells that do not involve a change in the nucleotide sequence, but instead involve a change in the way the genetic code is expressed. Epigenetic alterations may be just as important, or even more important, than genetic mutations in a cell's transformation to cancer. In cancers, loss of expression of genes occurs.
