Cholesterol precursor suppresses inflammatory response genes, causes atherosclerosis

Atherosclerosis - the hardening of arteries that is a primary cause of cardiovascular disease and death - has long been presumed to be the fateful consequence of complicated interactions between overabundant cholesterol and resulting inflammation in the heart and blood vessels.

Elevated c-Myc expression amplifies gene activity in tumor cells of multiple cancer types

For a cancer patient, over-expression of the MYC oncogene is a bad omen. Scientists have long known that in tumor cells, elevated levels of MYC's protein product, c-Myc, are associated with poor clinical outcomes, including increased rates of metastasis, recurrence, and mortality. Yet decades of research producing thousands of scientific papers on the subject have failed to consistently explain precisely how c-Myc exerts its effects across a broad range of cancer types. Until now, that is.

Fear hard to extinguish from the teenage brain

A new study by Weill Cornell Medical College researchers shows that adolescents' reactions to threat remain high even when the danger is no longer present. According to researchers, once a teenager's brain is triggered by a threat, the ability to suppress an emotional response to the threat is diminished which may explain the peak in anxiety and stress-related disorders during this developmental period.

Researchers identify genetic origins in 10% of aortic valve malformations

Researchers at the Sainte-Justine University Hospital Center and University of Montreal have identified genetic origins in 10% of an important form of congenital heart diseases by studying the genetic variability within families.

New understanding about function of MYC proteins

Scientists may have discovered why a protein called MYC can provoke a variety of cancers. Like many proteins associated with cancer, MYC helps regulate cell growth. A study carried out by researchers at the National Institutes of Health and colleagues found that, unlike many other cell growth regulators, MYC does not turn genes on or off, but instead boosts the expression of genes that are already turned on.

Intellectual disability often results from genetic causes that are not inherited

New research published Online First in The Lancet suggests that a high proportion of severe intellectual disability results from genetic causes that are not inherited. These findings are good news for parents, indicating a low risk of passing on the disorder to further children.

Inhibiting TRPV4 protects against diet-induced obesity, inflammation and insulin resistance

Ember Therapeutics, Inc., a company harnessing breakthroughs in brown fat biology and insulin sensitization to revolutionize the treatment of metabolic disease, today announced the publication of key preclinical data demonstrating that inhibition of the Transient Receptor Potential Vanilloid (TRPV) family of ion channels - specifically TRPV4 - resulted in activation of brown/beige fat and protection from diet-induced obesity, inflammation and insulin resistance. Ember holds an exclusive option to license these TRPV4 findings and technology.

Molecular link between thermogenesis and development of inflammation in fat cells

Flipping a newly discovered molecular switch in white fat cells enabled mice to eat a high-calorie diet without becoming obese or developing the inflammation that causes insulin resistance, report scientists from Dana-Farber Cancer Institute.

UNMCC researcher to investigate possible mechanism for cancer tumor development

Most of us think of DNA mutations as the culprits that cause cancer. Scott Ness, PhD, University of New Mexico Professor of Molecular Genetics and Microbiology and Associate Director at the UNM Cancer Center, thinks there may be another, more elusive culprit. If Dr. Ness is right his research, funded as part of the National Cancer Institute's Provocative Questions Project, might open a whole new arena in which to target anticancer drugs.

UCSD receives NCI grant to continue research into chronic lymphocytic leukemia

An international consortium of scientists studying chronic lymphocytic leukemia (CLL), based at the University of California, San Diego School of Medicine, has been awarded a 5-year, $20 million grant by the National Cancer Institute, part of the National Institutes of Health.

Study finds new regulator for heart formation

A new regulator for heart formation has been discovered by studying how embryonic stem cells adjust the packaging of their DNA. This approach to finding genetic regulators, the scientists say, may have the power to provide insight into the development of any tissue in the body - liver, brain, blood and so on.

Hundreds of new genes are involved in function and development of T-cells

A research team led by investigators at New York University and NYU School of Medicine has determined how cells that cause inflammatory ailments, such as Crohn's disease, multiple sclerosis, and arthritis, differentiate from stem cells and ultimately affect the clinical outcome of these diseases.

Type 2 diabetes may be derived from composition of specific intestinal flora

Whether you have an increased risk of developing type 2 diabetes, in the future may be derived from the composition of your intestinal flora. That according to new metagenomics research of an international consortium of scientists, including Jeroen Raes, connected to VIB and Vrije Universiteit Brussel. Metagenomics is the study of the genetic material of complete ecosystems, in this case the human intestine. This study appears in the leading journal Nature.

DNp63a protein employs epigenetics to keep cancer cells alive

Squamous cell carcinoma (SCC) is diagnosed in about 700,000 people in the United States every year. Commonly contributing to SCC is a protein called DNp63a - it goes abnormally high and the ability of a patient's body to kill cancer cells goes abnormally low. In many cases of SCC, it's just that simple. And science thought the function of DNp63a was simple, as well: the tumor suppressor gene p53 is responsible for recognizing and killing cancer cells, and in SCC, it's usually inactivated. It looked like high DNp63a repressed p53, made SCC.

Scientists discover 12 genetic markers for ED in prostate cancer patients after radiotherapy

In the first study of its kind, a research team led by Mount Sinai School of Medicine and Albert Einstein College of Medicine of Yeshiva University discovered 12 genetic markers associated with the development of erectile dysfunction (ED) in prostate cancer patients who were treated with radiation.

NCI-funded sequencing project aims to identify genetic links to colorectal cancer

Uncovering colon cancer's genetic roots is the focus of a new $13 million, four-year, National Cancer Institute-funded project at Fred Hutchinson Cancer Research Center. Ulrike (Riki) Peters, Ph.D., M.P.H., a member of the Hutchinson Center's Public Health Sciences Division, will lead the effort. She and her colleagues will use next-generation sequencing, a technique that captures entire genome sequences, to identify genetic links to colorectal cancer.

Fly neurons may uncover secrets of Alzheimer's disease

Although they're a common nuisance in the home, fruit flies have made great contributions to research in genetics and developmental biology. Now a Tel Aviv University researcher is again turning to this everyday pest to answer crucial questions about how neurons function at a cellular level - which may uncover the secrets of neurological disorders such as Alzheimer's disease.

Parts of the brain can evolve independently from each other

An Evolutionary Biologist at The University of Manchester, working with scientists in the United States, has found compelling evidence that parts of the brain can evolve independently from each other. It's hoped the findings will significantly advance our understanding of the brain.

Researchers identify several kinase inhibitors that help generate many iPSCs

The process researchers use to generate induced pluripotent stem cells (iPSCs)-a special type of stem cell that can be made in the lab from any type of adult cell-is time consuming and inefficient. To speed things up, researchers at Sanford-Burnham Medical Research Institute (Sanford-Burnham) turned to kinase inhibitors.
