Solving the mystery of a stubborn, and common, cancer gene

One of the major successes of decades of cancer research has been the development of drugs that specifically inactivate oncogenes, genes that function abnormally, causing cells to behave erratically, become malignant and ...

Tissue physics plays a key role in tumor growth

Cancer is a difficult disease to treat and to study, and can be caused by a range of genetic mutations. For instance, the mutated RAS gene causes a loss of structure in so-called epithelial tissue, a tissue type that lines ...

Uncovering epigenetic mechanisms regulating glioma growth

Northwestern Medicine investigators have discovered the epigenetic mechanisms involved in the regulation of multiple oncogenes in glioma cells, mechanisms that promote overall glioma tumor growth and resistance to therapy, ...

Oncogene

An oncogene is a gene that, when mutated or expressed at high levels, helps turn a normal cell into a cancer cell.

Many cells normally undergo a programmed form of death (apoptosis). Activated oncogenes can cause those cells to survive and proliferate instead. Most oncogenes require an additional step, such as mutations in another gene, or environmental factors, such as viral infection, to cause cancer. Since the 1970s, dozens of oncogenes have been identified in human cancer. Many cancer drugs target those DNA sequences and their products.
