Study provides insight into developing new treatment strategies for triple-negative breast cancer

A new study by University of Kentucky researchers provides insight into developing new treatment strategies for basal-like breast cancer, commonly known as triple-negative breast cancer. This cancer is associated with early metastasis and resistance to chemotherapy and occurs at women at a younger age.

Another role for protein Mer in novel, targeted cancer treatments

Since the mid-1990s, doctors have had the protein Mer in their sights - it coats the outside of cancer cells, transmitting signals inside the cells that aid their uncontrolled growth.

Researchers crack problem of predicting gene targets for PcG proteins

Cancer is usually attributed to faulty genes, but growing evidence from the field of cancer epigenetics indicates a key role for the gene "silencing" proteins that stably turn genes off inside the cell nucleus. A new study from Rice University and Baylor College of Medicine promises to speed research in the field by rapidly identifying the genes that epigenetic proteins can target for silencing.

Researchers discover over 500 genes that may contribute to pancreatic cancer

A global team led by scientists from The Methodist Hospital Research Institute has identified more than 500 genes that may cause or contribute to the development of pancreatic cancer.

JAK-STAT inhibitors reverse MS-like disease in mice

A new class of drugs completing clinical trials soon for rheumatoid arthritis should be examined as a treatment for multiple sclerosis, according to the authors of a University of Alabama at Birmingham study published today in the Proceedings of the National Academy of Sciences.

Researchers elucidate function of Codanin-1 protein

Within all our cells lies two meters of DNA, highly ordered in a structure of less than 10 micro meters in diameter. Special proteins called histones act as small building bricks, organising our DNA in this structure. Preservation of the structure is necessary to maintain correct function of our genes, making histones detrimental for maintaining a healthy and functional body.

Conference highlights studies on metabolism, aging and monarch butterfly migration

The Genetics Society of America's 53rd Annual Drosophila Research Conference, March 7-11 at the Sheraton Chicago Hotel & Towers, will showcase diverse efforts to understand basic biological processes through the easy-to-study fruit fly, Drosophila melanogaster, and other insects.

Genetically modified pig may hold keys to develop treatments for RP

A newly developed, genetically modified pig may hold the keys to the development of improved treatments and possibly even a cure for retinitis pigmentosa (RP), the most common inherited retinal disease in the United States.

Researchers discover mechanism by which lead alters nerve cells in the brain

Exposure to lead wreaks havoc in the brain, with consequences that include lower IQ and reduced potential for learning. But the precise mechanism by which lead alters nerve cells in the brain has largely remained unknown.

Aurora-A protein blocks proper functioning of tumor-suppressor p73

A protein abundantly found in treatment-resistant cancers holds an important tumor-suppressor out of the cell nucleus, where it would normally detect DNA damage and force defective cells to kill themselves, a team of scientists reports in the current Cancer Cell.

New RNA interference method holds promise for cancer, other diseases

For the past decade, scientists have been pursuing cancer treatments based on RNA interference - a phenomenon that offers a way to shut off malfunctioning genes with short snippets of RNA. However, one huge challenge remains: finding a way to efficiently deliver the RNA.

Elevated levels of two TLRs can trigger heart disease and diabetes

UC Davis scientists have uncovered a key suspect in the destructive inflammation that underlies heart disease and diabetes. The new research shows elevated levels of a receptor present on leucocytes of the innate immune response in people at risk for these chronic diseases.

Ventral striatum drives motivation during cognitive and motor actions

A team coordinated by Mathias Pessiglione, Inserm researcher at the -Centre de recherche en neurosciences de la Piti- Salp-tri-re- (Inserm/UPMC-Universit- Pierre and Marie Curie/CNRS) have identified the part of the brain driving motivation during actions that combine physical and mental effort: the ventral striatum.

Evolutionary biologist receives LRI grant for lupus research

Evolutionary biologist Harmit Singh Malik, Ph.D., of Fred Hutchinson Cancer Research Center, has received a $300,000 grant from the Lupus Research Institute to study the potential role of "genetic conflicts" in the development of lupus, an autoimmune disease.

Study reveals new guiding principles for cancer genomics

That our chromosomes can break and reshuffle pieces of themselves is nothing new; scientists have recognized this for decades, especially in cancer cells. The rules for where chromosomes are likely to break and how the broken pieces come together are only just now starting to come into view.

UCSF stem cell study suggests novel strategy for heart attack

A UCSF stem cell study conducted in mice suggests a novel strategy for treating damaged cardiac tissue in patients following a heart attack. The approach potentially could improve cardiac function, minimize scar size, lead to the development of new blood vessels - and avoid the risk of tissue rejection.

Deep brain stimulation can also affect respiratory function

Deep brain stimulation (DBS) has become a common treatment for patients with chronic pain or movement disorders. Now a unique set of experiments shows that electrical stimulation in some of the same brain areas can also affect respiratory function, according to a study in the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Researchers discover a connection of peroxisomal protein import and receptor export

The group of Prof. Dr. Ralf Erdmann at the Ruhr-Universit-t Bochum discovered a connection of peroxisomal protein import and receptor export. In the Journal of Biological Chemistry, they disclosed that enzymes only get imported into certain cell organelles (peroxisomes) upon coupling of their import to the recycling of their transport protein.

UC Riverside uncovers new insight into colon cancer

An international research team led by cell biologists at the University of California, Riverside has uncovered a new insight into colon cancer, the third leading cause of cancer-related deaths in the United States. The research provides potential new avenues for diagnosing and treating the disease.

Scientists search gene alterations in three-parent kids

Researchers from Australia want to find out if using the DNA of three parents will prevent children inheriting life-threatening diseases. They add that if the technique proves successful in preventing the transfer of mitochondrial DNA mutations from mothers to babies, then laws on the use of embryos will need to be changed to allow the procedure.
