Oncogene News and Research

RSS

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

Class of cells that arises in mammary glands during maternity has stem cell-like properties

These parity-induced mammary epithelial cells (PI-MEC) have the ability to self-renew over many generations and to differentiate into numerous cellular subtypes.

Bcl-6 oncogene - genetic target for lymphoma treatment

Results from a pre-clinical study show that the gene designated Bcl-6 is an oncogene -- that is, one with the potential to cause a normal cell to become cancerous -- but that certain peptide inhibitors can in effect inactivate it, according to a study to be presented today during the 46th Annual Meeting of the American Society of Hematology (ASH).

High levels of a protein called LRP6 can make cancer cells more aggressive

The protein's ability to enhance tumor development suggests that the gene that codes for LRP6 is an oncogene--a gene that contributes to tumor development when overactivated.

Significant steps to fight a deadly childhood muscle cancer

University of Utah scientists have taken significant steps to fight a deadly childhood muscle cancer by identifying some of the genetic events that cause the disease and then engineering mice that develop the tumors.

First whole-genome survey of where three commonly used retroviruses into human DNA

Retroviruses are one of the most common vehicles for delivering therapeutic payloads via gene therapy in animal models of disease and human patients.

Possible role for BK virus in development of prostate cancer

Now, new research by scientists at the University of Michigan Medical School suggests the intriguing possibility that this common virus also may play a role in prostate cancer – the second-leading cause of deaths from cancer in American men.

Identification of PIK3CA as an oncogene associated with brain cancers opens the door to new screening processes

Hotspots in two areas of a gene that encodes a specific signaling enzyme, or kinase, are vulnerable to a variety of mutations found in five types of brain cancers, according to a report published in the August 1 issue of the journal Cancer Research.

The p53 transcription factor plays a vital role in preventing cancer onset

Researchers at the Uppsala Branch of the Ludwig Institute for Cancer Research have discovered that the transcription factor Yin Yang 1 (YY1) is a novel regulator of the tumor suppressor p53, which is inactivated in at least half of all human cancers.

Microchip to track genetic signature of cancer and normal tissue

MicroRNAs (miRNAs), tiny pieces of genetic material that can serve as stop signs for gene expression and protein synthesis, are thought to be important in the development of cancer.

Cancer-causing gene identified that may play a key role in the development of leukemia and other cancers

Using genetically engineered mice, researchers at the Johns Hopkins Children's Center have identified a gene that functions as a cancer-causing gene (or oncogene) and may play a key role in the development of leukemia and other cancers in children and adults.

World's first gene therapy trial aimed at preventing cancer

The concept seems straightforward. If, at its heart, cancer is a disease of genes, then giving patients new genes should disarm cancer. Such treatment would replace missing or faulty genes that keep cell growth in check, or would flush the body with "super genes" that could attack and destroy cancer.

New gene presents a potent new target for breast cancer therapy

A gene known to promote longevity in animals has now been discovered to encode a tumor suppressor – a protein that helps prevent cancer, according to a study by a team of scientists from The University of Texas M. D. Anderson Cancer Center. The new gene, which was inactivated in two-thirds of patients studied, presents a potent new target for breast cancer therapy, the researchers say.
