Lack or loss of SIRT3 protein induces proliferation of breast cancer cells

Research published in the Cancer Cell journal in March was a significant step in knowing the causes of cancer better, especially breast cancer, revealing that the lack or loss of a protein in the cells known as SIRT3, induces the proliferation of this disease and thereby, this protein can be an may be a therapeutic target in the development of effective therapies for cancer. The research was led by Dra. Marcia Haigis of the Harvard Medical School, with the participation of Dr. Arkaitz Carracedo, from the Proteomics Laboratory at CIC bioGUNE.

Adipocytes associated with breast cancer could amplify 'aggressive' effect of tumors in obese patients

Apart from its direct effect on health (such as cardiovascular diseases and diabetes), obesity is increasingly suspected of playing a role in the prognosis of breast cancer and, in particular, its propensity to spread. However, no direct cause and effect relationship had been demonstrated until now. This breakthrough has finally been made through the collaborative work of two teams of researchers from Inserm, CNRS and the Université Paul Sabatier.

Huntingtin protein is responsible for metabolic imbalances in hypothalamus

In Huntington's disease, the mutant protein known as huntingtin leads to the degeneration of a part of the brain known as the basal ganglia, causing the motor disturbances that represent one of the most defining features of the fatal disease.

Scientists uncover SREBP-2 role in autophagy and cholesterol generation

Not all cholesterol is bad. Every cell requires it for growth - they either have to get cholesterol somewhere or they die. In a new study published April 6 in the journal Cell Metabolism, researchers from Sanford-Burnham Medical Research Institute and their collaborators found that a protein sensor known to balance cholesterol sources can also access a previously underappreciated cellular fat storage depot.

NIAID awards Aragen Bioscience with three subcontracts to advance preclinical studies

Aragen Bioscience, Inc., today announced it is a subcontractor on a National Institute of Allergy and Infectious Diseases contract for the preclinical development of monoclonal antibodies for the prevention and treatment of infectious diseases.

OSU chemist developing solution to nerve agent exposure

Scientists are working to develop a new drug that will regenerate a critical enzyme in the human body that “ages” after a person is exposed to deadly chemical warfare agents.

Post-infection treatment with NanoViricides FluCide reduces lung lesions caused by lethal influenza infection

NanoViricides, Inc. reports that post-infection treatment with its optimized FluCide™ drug candidates resulted in dramatic reduction in the number of lung lesions that are caused by a lethal influenza virus infection. These findings were seen in the most recent H1N1 influenza animal study.

NIPH study finds NDMA as one of the most carcinogenic compounds formed during CO2 capture

CO2 capture by means of amines is considered to be the most appropriate method to quickly begin with CO2 removal. During this capture process, some of the amines escaping the recycling process will be emitted into the air and will also form other compounds such as nitrosamines and nitramines.

Ubiquitine D gene may be linked to celiac disease

Celiac disease (CD) involves intolerance to gluten and, consequently, suffering chronic illness in the small intestine. It is a genetic disorder, the immunological indications of which can be traced in the human body prior to the everyday activities of future sufferers being affected. For example, persons with genetic antecedents for CD develop antibodies against the gene tTG (the enzyme known as tissue transglutaminase), even before the illness becomes active, due to a cell reaction against gluten.

Previously unknown mechanism blocks rewarding effects of alcohol on the brain

In order to develop new medications for alcoholism, researchers need to understand how alcohol acts on the brain's reward system. A previously unknown mechanism has been shown to block the rewarding effects of alcohol on the brain, reveals a thesis from the University of Gothenburg, Sweden.

Scientists effectively combine two methods used as vehicles to carry DNA into cell nuclei

Scientists at Polytechnic Institute of New York University (NYU-Poly) and at the NYU College of Dentistry have discovered a biochemical version of a principle well known among confectioners. Call it the "peanut butter and chocolate" rule: Sometimes two things work better together than alone.

Researchers identify genetic anomaly that may drive rare subset of prostate cancers

Researchers at the University of Michigan Comprehensive Cancer Center have identified a genetic anomaly that may drive the aggressive spread of a rare subset of prostate cancers.

Physical activity may moderate impact of stress on telomeres

UCSF scientists are reporting several studies showing that psychological stress leads to shorter telomeres - the protective caps on the ends of chromosomes that are a measure of cell age and, thus, health. The findings also suggest that exercise may prevent this damage.

Tumor cryoablation coupled with immunotherapy amplifies tumor immunity

Scientists at the Barbara Ann Karmanos Cancer Institute in Detroit today presented data at the American Association for Cancer Research's 102nd Annual Meeting 2011 showing that when tumor cryoablation – or the freezing of tumor tissue while preserving tumor-associated antigens – is coupled with immune system modulation, the procedures have the potential to initiate or amplify tumor immunity.

Certain microparticles help terminate inflammation

Scientists at Barts and The London School of Medicine and Dentistry and Harvard Medical School, Boston have found a way of mimicking the body's natural mechanism of fighting inflammation. During inflammation cells release very small particles termed 'microparticles' that retain features of their parent cell.

Preliminary discovery may help individualize prostate cancer screening in the future

Prostate cancer is the second leading cause of cancer-related death among American men. Yet population-wide screening programs have not reduced the number of deaths from the disease. By focusing screening programs on the men who are at greatest risk for aggressive disease or diagnosis at a young age, researchers think they could improve mortality rates and personalize the screening approach.

Scientists identify gene influencing levels of alcohol consumption

Scientists have identified a gene that appears to play a role in regulating how much alcohol people drink, in a study of over 47,000 people published today in Proceedings of the National Academy of Sciences.

Cocaine-addicted individuals show heightened response to drug-related images

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory and Stony Brook University (SBU) have conducted the most comprehensive study to date of how cocaine users respond to drug-related and other emotional stimuli, making use of comparisons with a matched control group and exploring the effects of recent cocaine use and abstinence. The findings appear in a paper published online in the European Journal of Neuroscience.

Scientists suggest genetic differences in breast tissue across ethnicities

Scientists from Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine are working on a series of genetic analyses that suggest the underlying differences among racial groups are present not just in tumors, but in normal tissue as well. Lisa Baumbach, Ph.D., associate research professor, and colleagues will present the full study results at the AACR 102nd Annual Meeting 2011, held here April 2-6.
