Researchers reveal surprising link between cell's skeleton and organ size

A group of scientists at the Instituto Gulbenkian de Ci-ncia, in Portugal, have uncovered a surprising link between the cell's skeleton and organ size. The team, led by Florence Janody, show in the journal Development, that one of the proteins that regulates the skeleton of the cell also acts to blocks activation of genes that promote cell survival and proliferation.

Light exposure can enhance brain's visual circuits

Any parent knows that newborns still have a lot of neurological work to do to attain fully acute vision. In a wide variety of nascent animals, genes provide them with only a rough wiring plan and then leave it to the developing nervous system to do its own finish work.

Cancer risk assessment in Lynch syndrome

Among various genetic mutations for individuals with Lynch syndrome, a hereditary cancer syndrome that carries a high risk of colon cancer and an above-normal risk of other cancers, researchers have identified mutations associated with a lower cancer risk and mutations associated with an increased risk for ovarian and endometrial cancer, according to a study in the June 8 issue of JAMA, a theme issue on cancer.

Weight loss following bariatric surgery may reduce risk of Alzheimer's

Obesity is a risk factor for Alzheimer's disease, but weight loss due to bariatric surgery may reduce the risk of this common dementia, a new study suggests. The results will be presented Sunday at The Endocrine Society's 93rd Annual Meeting in Boston.

Screening unhelpful in lowering deaths from ovarian cancer

New research shows that women regularly screened for ovarian cancer are just as likely to die from the disease. This comes as no surprise as there are still no adequate detection methods, says Ovarian Cancer Australia. Of the 1,200 Australian women diagnosed with ovarian cancer each year, 800 die, often because it is diagnosed too late to be treated.

Study links loss of PTEN gene with patient's response to melanoma therapy

Genetic analysis of the tumors from patients with advanced melanoma can clue researchers in to how well patients will respond to a therapy that targets the growth-promoting protein called BRAF, a researcher from the Perelman School of Medicine at the University of Pennsylvania will report on Monday, June 6 at the annual meeting of the American Society of Clinical Oncology.

Preliminary data from Ion PGM sequencer reveals German E. coli outbreak is a new hybrid strain

Life Technologies Corporation today announced that preliminary data from DNA sequencing performed in cooperation with the University Hospital Muenster, Germany, on the Ion Personal Genome Machine strongly suggests that the bacterium at the root of the deadly outbreak in Germany is a new hybrid type of pathogenic E. coli strains.

BGI genome sequencing identifies new super-toxic bacteria as cause of current European epidemic

The recent outbreak of an E. coli infection in Germany has resulted in serious concerns about the potential appearance of a new deadly strain of bacteria.

Researchers identify 'epigenetic fingerprints' of healthy volunteers, patients with common diseases

Until a decade, it was believed that differences between people were due solely to the existence of genetic changes, which are alterations in the sequence of our genes. The discoveries made during these last ten years show that beings with the same genetics like the twins and cloned animals may have different characteristics and disease due to epigenetic changes.

Enzyme Research journal publishes new peer-reviewed article involving Protandim

LifeVantage Corporation, the maker of Protandim, a clinically demonstrated, science-based therapy for the reduction of oxidative stress by the synergistic activation of Nrf2, announced today that a new peer-reviewed review article involving Protandim was published in the scientific journal Enzyme Research.

Johns Hopkins researchers solve long-standing mystery of Warburg effect

It's long been known that cancer cells eat a lot of sugar to stay alive. In fact, where normal, noncancerous cells generate energy from using some sugar and a lot of oxygen, cancerous cells use virtually no oxygen and a lot of sugar.

Scientists demonstrate why B cells exposed to chronic HIV shut down, how they can be reactivated

Scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have demonstrated why certain immune cells chronically exposed to HIV shut down, and how they can be reactivated.

Response Genetics' clinical approaches to improve cancer care to be presented at ASCO 2011

Response Genetics, Inc., a company focused on the development and sale of molecular diagnostic tests for cancer, announced today five presentations to be held during the 2011 American Society of Clinical Oncology Annual Meeting in Chicago, IL from June 3 to June 7, 2011.

Scientists identify chromosomal mutation responsible for excessive hair growth

Researchers in the Keck School of Medicine of the University of Southern California (USC), together with scientists in Beijing, China, have discovered a chromosomal mutation responsible for a very rare condition in which people grow excess hair all over their bodies.

FSU assistant professor unlocks mysteries of KSHV infection

In the early days of the AIDS epidemic, a once-rare form of cancer known as Kaposi's sarcoma emerged as a frequent harbinger of HIV. Its stigma was best illustrated by Tom Hanks, who portrayed a gay man trying to conceal the cancerous skin lesions from his co-workers in the 1993 movie "Philadelphia."

Researchers discover genomic control system that regulates gut formation in sea-urchin embryos

For all animals, development begins with the embryo. It is here that uniform cells divide and diversify, and blueprints are laid for future structures, like skeletal and digestive systems. Although biologists have known for some time that signaling processes-messages that tell a cell to express certain genes so as to become certain parts of these structures-exist at this stage, there has not been a clear framework explanation of how it all comes together.

Study provides insights into evolution and origins of MRSA

A distinctly new type of methicillin resistant Staphylococcus aureus (MRSA) that is not detected by traditional genetic screening methods has been discovered in patients in Irish hospitals according to research to be published in the journal Antimicrobial Agents and Chemotherapy.

KGI scientists identify new gene regulator that keeps hearts healthy even under intense exercise

Providing a medical explanation for why exercise is good for the heart, a team of scientists from Brazil pursuing a study that started in Dr. Ian Phillips' lab at Keck Graduate Institute (KGI) has discovered a new gene regulator called MicroRNA 29 that keeps hearts healthy even under intense exercise.

Johns Hopkins researchers solve mystery of Warburg effect

It’s long been known that cancer cells eat a lot of sugar to stay alive. In fact, where normal, noncancerous cells generate energy from using some sugar and a lot of oxygen, cancerous cells use virtually no oxygen and a lot of sugar. Many genes have been implicated in this process and now, reporting in the May 27 issue of Cell, researchers at the Johns Hopkins University School of Medicine have discovered that this so-called Warburg effect is controlled.

Microscopic worms in space

A space flight by millions of microscopic worms could help us overcome the numerous threats posed to human health by space travel. The Caenorhabditis elegans (C. elegans) have also given experts an insight into how to block muscle degradation in the sick and elderly.
