Berkeley Lab researchers resolve EGFR activation mystery

Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have provided important new details into the activation of the epidermal growth factor receptor (EGFR), a cell surface protein that has been strongly linked to a large number of cancers and is a major target of cancer therapies.

RNF20 protein required for MLL-rearranged leukemia amplification

Acute myeloid leukemia (AML) is an aggressive blood cancer that is currently incurable in 70% of patients. In a bold effort, CSHL scientists are among those identifying and characterizing the molecular mechanisms responsible for this cancer in order to generate potential new therapeutics.

MicroRNA can be used to define four subtypes of triple-negative breast cancer

A new, large-scale study of triple-negative breast cancer shows that small molecules called microRNA can be used to define four subtypes of this aggressive malignancy.

Tumor suppressor mutant may predict poor outcome in breast cancer

An oncogenic variant of the Krüppel-like family 6 tumor suppressor gene appears to play a role in driving breast cancer metastasis and may be a prognostic marker for poor patient outcome, report researchers.

Previously poorly investigated signalling pathway crucial for proliferation of prostate cancer cells

A previously poorly investigated signalling pathway is crucial for the growth and proliferation of prostate cancer cells. An international research team discovered this when studying the enzyme "soluble adenylyl cyclase" that produces the second messenger molecule cAMP.

Study provides new insight on cancer prevention

Clear communication between cells is essential to every aspect of the body's internal function. But since cells can't talk, or send emails, how do they communicate?

Scientists uncover key mechanism that links obesity and diabetes with cancer

Sugars are needed to provide us with energy and in moderate amounts contribute to our well-being. Sustained high levels of sugars, as is found in diabetics, damages our cells and now is shown that can also increase our chance to get cancer: The dose makes the poison as Paracelsus said.

Bioelectric signals can identify cells that are likely to develop into tumors

Biologists at Tufts University School of Arts and Sciences have discovered a bioelectric signal that can identify cells that are likely to develop into tumors. The researchers also found that they could lower the incidence of cancerous cells by manipulating the electrical charge across cells' membranes.

Existing cardiomyocytes contribute to formation of new heart cells after attack

Injecting specialized cardiac stem cells into a patient's heart rebuilds healthy tissue after a heart attack, but where do the new cells come from and how are they transformed into functional muscle?

Biomaterials as neural stem cell niches can help repair damage in the CNS

Despite recent advances in understanding the mechanisms of nerve injury, tissue-engineering solutions for repairing damage in the central nervous system (CNS) remain elusive, owing to the crucial and complex role played by the neural stem cell (NSC) niche. This zone, in which stem cells are retained after embryonic development for the production of new cells, exerts a tight control over many crucial tasks such as growth promotion and the recreation of essential biochemical and physical cues for neural cell differentiation.
