Shorter sleep provides more permissive environment for expression of obesity related genes

Toss out another old wives' tale: Sleeping too much does not make you fat. Quite the opposite, according to a new study examining sleep and body mass index (BMI) in twins, which found that sleeping more than nine hours a night may actually suppress genetic influences on body weight.

Experts identify new gene that could help development of human fertility treatments

Experts from Durham University have identified a new gene that could help the development of fertility treatments in humans in the future.

Beta-carotene-derived molecules have opposite effect in the body

New research suggests that there could be health hazards associated with consuming excessive amounts of beta-carotene.

Scientists are working out how sequencing the human genome can help treat disease

Though the human genome has been sequenced, scientists are still trying to figure out how the accomplishment can help people, for example, how it can be used to treat disease. As University of Massachusetts Amherst geneticist Jacob Mayfield notes, "It was easy to think of the human genome as the big prize, but what we realize now is, it's just a foot in the door."

CHR-3996 pill shows promise against advanced cancers

Scientists have shown that a brand new type of cancer pill that exploits the emerging field of epigenetics is safe for human use, according to a Phase I trial reported today in Clinical Cancer Research.

FANCM gene plays key role in recombination of genetic information during inheritance

Scientists of KIT and the University of Birmingham have identified relevant new functions of a gene that plays a crucial role in Fanconi anemia, a life-threatening disease. The FANCM gene is known to be important for the stability of the genome.

Human iPS cells accrue genetic changes at about the same rate as replicating cells

A team of researchers from Johns Hopkins University and the National Human Genome Research Institute has evaluated the whole genomic sequence of stem cells derived from human bone marrow cells—so-called induced pluripotent stem (iPS) cells—and found that relatively few genetic changes occur during stem cell conversion by an improved method.

New class of drugs hold promise against aggressive forms of pancreatic cancer

Cancer Research UK-funded scientists have shown how a promising new class of drugs might be used to treat aggressive forms of pancreatic cancer, according to a study published in Nature.

Memory aging and brain maintenance

Aging may seem unavoidable, but that's not necessarily so when it comes to the brain. So say researchers in the April 27th issue of the Cell Press journal Trends in Cognitive Sciences explaining that it is what you do in old age that matters more when it comes to maintaining a youthful brain not what you did earlier in life.

Mirror-microRNAs control multiple aspects of brain function

Our genes control many aspects of who we are - from the colour of our hair to our vulnerability to certain diseases - but how are the genes, and consequently the proteins they make themselves controlled? Researchers have discovered a new group of molecules which control some of the fundamental processes behind memory function and may hold the key to developing new therapies for treating neurodegenerative diseases.

Breast-fed babies may have healthy gut microbial population

Early colonization of the gut by microbes in infants is critical for development of their intestinal tract and in immune development. A new study, published in BioMed Central's open access journal Genome Biology, shows that differences in bacterial colonization of formula-fed and breast-fed babies leads to changes in the infant's expression of genes involved in the immune system, and in defense against pathogens.

Detrimental effect of tetracycline on male reproductive function, sperm viability of pseudoscorpions

In a paper published today in Nature's open access journal Scientific Reports, researchers at the University of Nevada, Reno report that male pseudoscorpions treated with the antibiotic tetracycline suffer significantly reduced sperm viability and pass this toxic effect on to their untreated sons. They suggest that a similar effect could occur in humans and other species.

Researchers use Moffitt's Total Cancer Care to create designer lymph nodes

Researchers at Moffitt Cancer Center are in the first phase of creating "designer lymph nodes." Designer lymph nodes are built with specialized gene-modified cells that are injected into patients and produce a pre-planned immunologic response for cancer patients locally and then throughout their bodies. The researchers are examining a cancer vaccine "boosting" effect of the manufactured lymph nodes in patients with advanced melanoma.

Researchers discover gene for new form of intellectual disability

Researchers at the Centre for Addiction and Mental Health (CAMH) led a study discovering a gene for a new form of intellectual disability, as well as how it likely affects cognitive development by disrupting neuron functioning.

Gas NO plays a fundamental regulatory role in controlling bacterial function

Bacteria provide a well-known playground for scientists and the evolution of these earliest life forms has shed important perspective on potential therapies for some of the most common, deadly diseases. Researchers at Case Western Reserve University School of Medicine have now discovered that, the gas nitric oxide (NO), produced in all cells of the human body for natural purposes, plays a fundamental regulatory role in controlling bacterial function, via a signaling mechanism called S-nitrosylation (SNO), which binds NO to protein molecules.

Kras gene triggers metabolic changes that fuel cancer cells

Researchers at Dana-Farber Cancer Institute have shown that advanced pancreatic cancers in mice can't survive without continued expression of a mutant oncogene that "rewires" key metabolic pathways to fuel the cancer cells.

Combination of Velcade and Fasudil could treat NSCLC

A common cancer drug and a drug used for a rare condition affecting the heart could together treat an aggressive form of lung cancer called non-small cell lung cancer (NSCLC), according to a study published in Cell today.

FDA approves Novartis’ Afinitor for treatment of renal angiomyolipomas and TSC

Novartis Pharmaceuticals Corporation announced today that the US Food and Drug Administration (FDA) approved Afinitor (everolimus) tablets for the treatment of adult patients with kidney tumors known as renal angiomyolipomas and tuberous sclerosis complex (TSC), who do not require immediate surgery.

Experimental drug for autism works effectively in laboratory mice: Study

A new experimental drug has shown promise in autism symptoms in mice. Researchers from the National Institutes of Mental Health and Pfizer reported Wednesday that an experimental compound, called GRN-529, increased social interactions and lessened repetitive self-grooming behavior in a strain of mice bred to display autism-like behaviors.

Fragile-X gene linked with disrupting de novo mutations in children with autism

A team led by scientists at Cold Spring Harbor Laboratory (CSHL) publishes research today indicating a striking association between genes found disrupted in children with autism and genes that are targets of FMRP, the protein generated by the gene FMR1, whose dysfunction causes Fragile-X syndrome.
