Scientists discover three unexpected RNAs involved in diabetes cell-death pathway

Excess nutrients, such as fat and sugar, don't just pack on the pounds but can push some cells in the body over the brink. Unable to tolerate this "toxic" environment, these cells commit suicide.

Healthy diet might help reduce risk of macular degeneration

Eating a diet high in vitamin D, as well as the nutrients betaine and methionine, might help reduce the risk of macular degeneration, according to new research conducted by Tufts Medical Center scientists. Their study of identical twins from the US World War II Twin Registry also found that the more a person smoked, the higher their risk of developing macular degeneration.

Tel Aviv University researcher finds link between back pain and genetics

A common complaint, back pain is one of the many side effects of aging. Over three quarters of the population experience it at some point, and until now, researchers have had little conclusive proof of the causes and mechanisms of the pain.

Cleavage stage embryo with aneuploidy can undergo genetic normalisation process

Professor William G. Kearns told the annual meeting of the European Society of Human Reproduction and Embryology that a three-day-old embryo with an incorrect number of chromosomes was capable of undergoing "a dynamic process of genetic normalisation" so that by day five, when it had developed to the blastocyst stage, it had become euploid, with the correct number of chromosomes.

Autism Speaks announces significant findings from largest study of twins with ASD

Autism Speaks, the world's largest autism science and advocacy organization, joined in announcing significant findings from the largest known study of twins with autism spectrum disorder.

Fruit flies with poor posture help scientists understand human intellectual disability

Clumsy fruit flies with poor posture are helping an international team of scientists understand inherited intellectual disability in humans - and vice versa.

Research addresses chromosomal imbalance in embryos

Joint research between the University of Kent's Professor Darren Griffin, London Bridge Fertility Centre and BlueGnome Ltd has addressed chromosomal imbalance in embryos, a condition that is currently the major cause of pregnancy loss in IVF.

New insight into oocyte chromosome abnormalities

Ovarian stimulation undertaken by women of advanced maternal age receiving fertility treatment may be disrupting the normal pattern of meiosis - a critical process of chromosome duplication followed by two specialised cell divisions in the production of oocytes and sperm - and leading to abnormalities of chromosome copy numbers that result in IVF failure, pregnancy loss or, more rarely, the birth of affected children with conditions such as Down's syndrome, which is caused by the inheritance of three copies of chromosome 21.

Study: Diet soda negatively impacts waistline

You are making a healthier choice when opting for a diet soda instead of a calorie-laden drink, but beware that you don't sabotage your good behavior by indulging in fat-adding foods.

MGH researchers discover new plant compounds that block blood vessel growth

Massachusetts General Hospital (MGH) researchers have discovered the first of an entirely new class of antiangiogenesis drugs - agents that interfere with the development of blood vessels.

STSI receives NIH grant to conduct heart-based research

Researchers looking to find a root cause for heart attacks and coronary artery disease will soon begin using a novel investigative approach that borders on science fiction as they work toward the holy grail of American medicine: preventing the nation's No. 1 killer.

GWAS identifies 15 gene variants responsible for diversity of white blood cell counts

A trio of large-scale genome-wide association studies, or GWAS, have identified more than 15 gene variants responsible for the diversity of white blood cell counts among whites, African-Americans, and Japanese.

Potential new treatment for rare, inherited metabolic disease

The rare disorder alpha-mannosidosis can cause serious damage to the nervous system and other organ systems. In Tromsø, Norway, researchers have been studying the disease for 20 years - and a treatment may soon be available.

Two defective genes may cause telomere elongations in cancer cells: Study

Scientists at Johns Hopkins have provided more clues to one of the least understood phenomena in some cancers: why the "ends caps" of cellular DNA, called telomeres, lengthen instead of shorten.

Scientists discover enzyme that can regulate breast cancer development

Researchers at Cold Spring Harbor Laboratory (CSHL) have identified an enzyme that appears to be a significant regulator of breast cancer development. Called PTPN23, the enzyme is a member of a family called protein tyrosine phosphatases, or PTPs, that plays a fundamental role in switching cell signaling on and off.

Epigenetics affects whether or not stem cells differentiate

Adult stem cells and progenitor cells may not come with a clean genetic slate after all. That's because a new report in the FASEB Journal shows that adult stem or progenitor cells have their own unique "epigenetic signatures," which change once a cell differentiates. This is important because epigenetic changes do not affect the actual make up in a cell's DNA, but rather, how that DNA functions.

Ovarian cancer molecular updates

In a new study a genetic mutation was found in the most common form of ovarian cancer. This according to the US scientists could pave the way for a more effective treatment of the disease. The detailed genetic map already helped scientists identify existing drugs with the potential for treating the mutations found in ovarian cancer tumors and also identified mutations that could respond to new drugs.
