New study finds brain tumors can arise from neurons

(Medical Xpress)—Researchers from the US and Japan have shown that an aggressive type of brain tumor can arise from normal cells in the central nervous system such as neurons. The cells revert to an earlier, undifferentiated ...

Scientists ID gene responsible for deadly glioblastoma

Scientists have identified an oncogene (a cancer-causing gene) responsible for glioblastoma, the deadliest brain tumor. The discovery offers a promising new treatment target for a cancer that is always fatal.

New compound discovered that rapidly kills liver cancer

Scientists have identified a new compound that rapidly kills hepatocellular carcinoma (HCC) cells, the most common form of liver cancer and fifth most common cancer worldwide, while sparing healthy tissue. The compound, Factor ...

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 ...

Novel math formula predicts success of certain cancer therapies

Carefully tracking the rate of response of human lung tumors during the first weeks of treatment can predict which cancers will undergo sustained regression, suggests a new study by researchers at the Stanford University ...

Cancer cells and stem cells share same origin: study

Oncogenes are generally thought to be genes that, when mutated, change healthy cells into cancerous tumor cells. Scientists at the Keck School of Medicine of the University of Southern California (USC) have proven that those ...

Study identifies a cause of resistance to colon cancer treatment

Doctors and researchers of Hospital del Mar and its research institute, the IMIM, have lead a study describing a new pharmacological resistance to cancer. This new mechanism is a mutation in an oncogene called EGFR (epidermal ...

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.
