Amniotic fluid stem cells have potential to become specialized cell types, say researchers

For the first time, scientists have demonstrated that stem cells found in amniotic fluid meet an important test of potential to become specialized cell types, which suggests they may be useful for treating a wider array of diseases and conditions than scientists originally thought.

Overexpression of NCX1 does not by itself lead to contraction abnormalities in the heart

Researchers from the Center for Translational Medicine at Thomas Jefferson University have found that the overexpression of a sodium/calcium exchanger, without changes in other ion transport pathways commonly observed in heart failure, does not by itself lead to contraction abnormalities in the heart.

Winship-led team identifies a way to exploit cancer cells' taste for glucose

The pedal-to-the-metal signals driving the growth of several types of cancer cells lead to a common switch governing the use of glucose, researchers at Winship Cancer Institute of Emory University have discovered.

Study examines how dietary restriction and high-caloric diet influence biochemical responses

Researchers at Mount Sinai School of Medicine set out to address a question that has been challenging scientists for years: How do dietary restriction-and the reverse, overconsumption-produce protective effects against aging and disease?

Complicated flow of cellular messages can lead to self-destruction of brain cells, says new study

Scientists at the Brain Research Centre, a partnership of the University of British Columbia Faculty of Medicine and Vancouver Coastal Health Research Institute, have uncovered new information about the mechanism by which brain cells die following a stroke, as well as a possible way to mitigate that damage. The results of the study were recently published online in Nature Medicine.

Gene deletion can increase common complication of bone marrow transplants

A commonly inherited gene deletion can increase the likelihood of immune complications following bone marrow transplantation, an international team of researchers reports in the November 22 advance online issue of Nature Genetics.

New target may promote development of novel therapies for chronic sinusitis

A protein known to stimulate blood vessel growth has now been found to be responsible for the cell overgrowth in the development of polyps that characterize one of the most severe forms of sinusitis, a study by Johns Hopkins researchers suggests. The finding gives scientists a new target for developing novel therapies to treat this form of the disease, which typically resists all current treatments.

Experiments explain factors behind common malarial symptoms

When people have malaria, they are infected with Plasmodium parasites, which enter the body from the saliva of a mosquito, infect cells in the liver, and then spread to red blood cells. Inside the blood cells, the parasites replicate and also begin to expose adhesive proteins on the cell surface that change the physical nature of the cells in the bloodstream.

Genes from same 'family' interact with each other to prevent skin cancer, says new study

CANCER RESEARCH UK scientists have shown, for the first time, how two genes from the same 'family' can interact with each other to stop cancer in its tracks - according to new findings published in Molecular Cell.

Scientists discover new potential target for treating non-Hodgkin's lymphoma

Physician-scientists from Weill Cornell Medical College have discovered a molecular mechanism that may prove to be a powerful target for the treatment of non-Hodgkin's lymphoma, a type of cancer that affects lymphocytes, or white blood cells. By exploiting this mechanism, researchers have been able to powerfully suppress tumor formation in lab testing and in animal models.

Bacteria help in preventing inflammation after skin injury

On the skin's surface, bacteria are abundant, diverse and constant, but inflammation is undesirable. Research at the University of California, San Diego School of Medicine now shows that the normal bacteria living on the skin surface trigger a pathway that prevents excessive inflammation after injury.

Cancer promoting gene identified

Virginia Commonwealth University Massey Cancer Center and VCU Institute of Molecular Medicine researchers have identified a gene that may play a pivotal role in two processes that are essential for tumor development, growth and progression to metastasis. Scientists hope the finding could lead to an effective therapy to target and inhibit the expression of this gene resulting in inhibition of cancer growth.

Discovery holds promise in fighting cancer, AIDS and autoimmune disorders

Researchers at the University of Alabama at Birmingham (UAB) have uncovered the genetic identity of a cellular receptor for the immune system's first-response antibody, a discovery that sheds new light on infection control and immune disorders.

Protector of single cysteines discovered

We've all read studies about the health benefits of having a life partner. The same thing is true at the molecular level, where amino acids known as cysteines are much more vulnerable to damage when single than when paired up with other cysteines.

Emotionally abused children may face accelerated cellular aging as adults

Children who suffer physical or emotional abuse may be faced with accelerated cellular aging as adults, according to new research from Butler Hospital and Brown University.

Whole genome analysis identifies 43 genetic loci contributing to lipoprotein metabolism

Using highly precise measurements of plasma lipoprotein concentrations determined by nuclear magnetic resonance spectroscopy (NMR), researchers led by Daniel Chasman at Brigham and Women's Hospital and Harvard Medical School in Boston, MA, the Framingham Heart Study in Framingham, and the PROCARDIS consortium in Stockholm, Sweden and Oxford, England performed genetic association analysis across the whole genome among 17,296 women of European ancestry from the Women's Genome Health Study.

Study reveals effectiveness of radiation therapy in achieving local control and palliation in patients with PNTs

Radiation therapy is effective in achieving local control and palliation in patients with pancreatic neuroendocrine tumors (PNTs), despite such tumors being commonly considered resistant to radiation therapy, according to a largest of its kind study in the November 15 issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO).

Ligand Pharmaceuticals' SARM LGD-4033 study data presented at the Gerontology Society of America meeting

Ligand Pharmaceuticals Incorporated today announced that data from a preclinical study on its selective androgen receptor modulator (SARM) LGD-4033 was featured in a poster presentation at the 62nd Annual Meeting of the Gerontology Society of America in Atlanta. LGD-4033 exhibited desirable in vivo efficacy on skeletal muscle and bone measurements in animal models of male hypogonadism and postmenopausal osteoporosis.

SCF founder Sabrina Cohen recognized as a WebMD 2009 Health Hero

Sabrina Cohen, founder of The Sabrina Cohen Foundation for Stem Cell Research (SCF), was just recognized as a WebMD 2009 Health Hero. She will receive national media attention with a full-page article about her personal story of triumph and courage, and shares the spotlight with celebrity movie-star, Scarlett Johansson and other Health Heroes in the November/December issue.

Discovery of Th22 cells may help in developing effective therapies for chronic skin and respiratory diseases

The newly discovered Th22 cells are a previously unknown subset of T helper cells. T helper cells are white blood cells that help activate other immune cells when the body is infected by viruses or bacteria. At the same time they help the body to tolerate own tissue and to prevent or curb inflammation.
