Study suggests possible way to halt cancer development in premalignant cells

Scientists have uncovered a survival mechanism that occurs in breast cells that have just turned premalignant-cells on the cusp between normalcy and cancers-which may lead to new methods of stopping tumors.

New research identifies mechanism to make cancer cells respond to chemotherapy

Breast cancer characterized as "triple negative" carries a poor prognosis, with limited treatment options. In some cases, chemotherapy doesn't kill the cancer cells the way it's supposed to. New research from Western University explains why some cancer cells don't respond to chemotherapy, and identifies a mechanism to rectify that.

EGFR gums up cell's miRNA-processing machinery under oxygen starvation conditions

Even while being dragged to its destruction inside a cell, a cancer-promoting growth factor receptor fires away, sending signals that thwart the development of tumor-suppressing microRNAs before it's dissolved, researchers reported in an early online publication at Nature.

Research findings reveal promising new anti-addiction drug

Researchers at Johns Hopkins have unraveled the molecular foundations of cocaine's effects on the brain, and identified a compound that blocks cravings for the drug in cocaine-addicted mice.

Researchers make gold nanoparticles more effective against ovarian cancer cells

Positively charged gold nanoparticles are usually toxic to cells, but cancer cells somehow manage to avoid nanoparticle toxicity. Mayo Clinic researchers found out why and determined how to make the nanoparticles effective against ovarian cancer cells.

Diachisis can occur during subacute phase of ischemic stroke, find USF researchers

While the effects of acute stroke have been widely studied, brain damage during the subacute phase of stroke has been a neglected area of research. Now, a new study by the University of South Florida reports that within a week of a stroke caused by a blood clot in one side of the brain, the opposite side of the brain shows signs of microvascular injury.

Scientists design 'fishing' technique to show health benefits of foods

New research suggests that a compound abundant in the Mediterranean diet takes away cancer cells' "superpower" to escape death.

Researchers pinpoint catalytic trigger for onset of Alzheimer's disease

Researchers have pinpointed a catalytic trigger for the onset of Alzheimer's disease - when the fundamental structure of a protein molecule changes to cause a chain reaction that leads to the death of neurons in the brain.

Researchers examine how BRD4 contributes to sustained presence of NF-kappa B in cancer cells

In a new study described in the journal Oncogene, researchers reveal how a key player in cell growth, immunity and the inflammatory response can be transformed into a primary contributor to tumor growth.

Researchers use new analysis method to determine genes that result in cell death

Lethal and rescuer genes are defined as genes that when inactivated result in cell death or enhanced cell growth, respectively. The ability to identify these genes in large-scale automated screening campaigns could lead to the discovery of valuable new drug targets.

Berlin scientists plan to research on neurodegenerative diseases

Now, both have signed a cooperation agreement to seal their close scientific collaboration. The objective is to combine existing expertise and to bring new outstanding researchers to Berlin.

Researchers demonstrate how EGF accelerates division of cell nucleus

Biologists at Heidelberg University have discovered new approaches for the treatment of cancer. They investigated how a special signalling molecule, the epidermal growth factor (EGF), stimulates the separation of chromosomes in the cell. The researchers were able to demonstrate that EGF accelerates the division of the cell nucleus, i.e. mitosis, as well as boosts precision in chromosome segregation.

Novel drug may increase the effectiveness of radiation therapy for brain cancer

A novel drug may help increase the effectiveness of radiation therapy for the most deadly form of brain cancer, report scientists at Virginia Commonwealth University Massey Cancer Center. In mouse models of human glioblastoma multiforme (GBM), the new drug helped significantly extend survival when used in combination with radiation therapy.

ALKBH7 protein plays key role in controlling programmed necrosis pathway

When cells suffer too much DNA damage, they are usually forced to undergo programmed cell death, or apoptosis. However, cancer cells often ignore these signals, flourishing even after chemotherapy drugs have ravaged their DNA.

Inherited mutations in p53 gene put people at high risk of developing cancers

The understanding of how a powerful protein called p53 protects against cancer development has been upended by a discovery by Walter and Eliza Hall Institute researchers. More than half of human cancers carry defects in the gene for p53, and almost all other cancers, with a normal p53 gene, carry other defects that somehow impair the function of the p53 protein. Inherited mutations in the p53 gene put people at a very high risk of developing a range of cancers.

Mouse study shows leukemia halts accumulation of toxic proteins linked to Parkinson's disease

Researchers at Georgetown University Medical Center have used tiny doses of a leukemia drug to halt accumulation of toxic proteins linked to Parkinson's disease in the brains of mice. This finding provides the basis to plan a clinical trial in humans to study the effects.

Researchers find a way the body can remove injured axons

Many medical issues affect nerves, from injuries in car accidents and side effects of chemotherapy to glaucoma and multiple sclerosis. The common theme in these scenarios is destruction of nerve axons, the long wires that transmit signals to other parts of the body, allowing movement, sight and sense of touch, among other vital functions.

Research opens door to new drug therapies for Parkinson's disease

McGill University researchers have unlocked a new door to developing drugs to slow the progression of Parkinson's disease. Collaborating teams led by Dr. Edward A. Fon at the Montreal Neurological Institute and Hospital -The Neuro, and Dr. Kalle Gehring in the Department of Biochemistry at the Faculty of Medicine, have discovered the three-dimensional structure of the protein Parkin.

Seven-year quest to understand how breast cancer cells resist treatment

A seven-year quest to understand how breast cancer cells resist treatment with the targeted therapy lapatinib has revealed a previously unknown molecular network that regulates cell death.
