RhoGDI2 protein helps prevent bladder cancer metastasis to the lungs

The diagnosis of localized bladder cancer carries an 80 percent five-year survival rate, but once the cancer spreads, the survival rate at even three years is only 20 percent. A major study published today in the Journal of Clinical Investigation not only shows how bladder cancer metastasizes to the lungs but pinpoints a method for stopping this spread.

Study addresses how human body controls gamma-herpesviruses

New research from the Trudeau Institute addresses how the human body controls gamma-herpesviruses, a class of viruses thought to cause a variety of cancers. The study, carried out in the laboratory of Dr. Marcia Blackman, awaits publication in The Journal of Immunology.

Researchers identify molecule that helps decrease acute GVHD severity

Researchers have identified a molecule that helps control the severity of graft-versus-host disease, a life-threatening complication for many leukemia patients who receive a bone-marrow transplant.

Human diseases with Drosophila counterparts discussed at annual conference

More than two-thirds of human genes have counterparts in the well-studied fruit fly, Drosophila melanogaster, so although it may seem that humans don't have much in common with flies, the correspondence of our genetic instructions is astonishing. In fact, there are hundreds of inherited diseases in humans that have Drosophila counterparts.

Pfizer’s Prevnar 13 Phase 3 study for pneumococcal disease meets all study endpoints

Pfizer Inc. announced today that data from a Phase 3 study of Prevnar 13 (Pneumococcal 13-valent Conjugate Vaccine [Diphtheria CRM197 Protein]) met all study endpoints, showing immunogenicity and establishing a safety profile in children and adolescents aged 5 through 17 years.

Insulin and nutrition keep blood stem cells from differentiating into mature blood cells

UCLA stem cell researchers have shown that insulin and nutrition keep blood stem cells from differentiating into mature blood cells in Drosophila, the common fruit fly, a finding that has implications for studying inflammatory response and blood development in response to dietary changes in humans.

Top-line results from Inviragen's INV21 Phase 1 trial on HFMD

Inviragen today reported top-line results of a placebo-controlled, randomized Phase 1 trial of INV21, the Company's highly purified virus particle vaccine against Hand, Foot and Mouth Disease (HFMD) caused by enterovirus 71.

Gastrointestinal progenitor cells could be coaxed into making insulin

A study by Columbia researchers suggests that cells in the patient's intestine could be coaxed into making insulin, circumventing the need for a stem cell transplant. Until now, stem cell transplants have been seen by many researchers as the ideal way to replace cells lost in type I diabetes and to free patients from insulin injections.

Researchers identify genetic signature for eosinophilic esophagitis

Researchers have identified a genetic signature for a severe, often painful food allergy – eosinophilic esophagitis – that could lead to improved diagnosis and treatment for children unable to eat a wide variety of foods.

Chlamydia has evolved more actively than previously thought

In a study released today in Nature Genetics, researchers have found that Chlamydia has evolved more actively than was previously thought. Using whole genome sequencing the researchers show that the exchange of DNA between different strains of Chlamydia to form new strains is much more common than expected.

Researchers produce extensive catalog of genes expressed in human islets

A new JDRF-funded study shows that many of the genes known to play a role in type 1 diabetes (T1D) are expressed in pancreatic beta cells, suggesting that the cell responsible for producing insulin may be playing a part in its own destruction to lead to T1D.

Sientra’s breast implant approved by the U.S. FDA

The implant, manufactured by Santa Barbara-based Sientra, can be used for breast tissue reconstruction for women of any age and for breast augmentation in women 22 or older. The approval resulted from three years of clinical studies on almost 1,800 patients. Tightening of the area around the implant, re-operation, implant removal, uneven appearance and infection were some of the complications experienced during the study. Sientra is required to continue studies on the implant's long-term safety, effectiveness and risks of rare diseases under the approval.

Five new genetic mutations linked with Crohn's disease in Ashkenazi Jews

In the largest study of its kind, researchers from Mount Sinai School of Medicine have discovered five new genetic mutations associated with Crohn's disease in Jews of Eastern European descent, also known as Ashkenazi Jews.

New vaccination strategy may effectively eradicate HIV-1 infection

In what may prove to be a major step forward for the treatment of HIV-1 infection, scientists have discovered an effective way to eliminate a notoriously persistent form of the virus that does not respond to current therapies. The research, published online by Cell Press on March 8th from the journal Immunity, describes a vaccination strategy that may be essential for successful eradication efforts and should therefore be considered for future clinical trials.

HDAC inhibitors flush latent HIV infection from hiding

A team of researchers at the University of North Carolina at Chapel Hill have successfully flushed latent HIV infection from hiding, with a drug used to treat certain types of lymphoma.

Some bone marrow cells could prevent rejection of transplanted kidney in recipients: Study

Researchers transplanted certain cells from the kidney donor’s bone marrow along with the new organ. Five of eight transplant recipients who tried the method so far were off immune-suppressing medication up to 2½ years later, the researchers reported Wednesday. The preliminary results were considered important enough to be published in the journal Science Translational Medicine even though the study still is under way, because the technique worked for patients who didn’t have well-matched or related donors.

Bellicum raises $20M in Series B financing

Bellicum Pharmaceuticals, Inc. today announced that it has raised $20 million in a Series B financing. The funding will be used to advance its lead CaspaCIDe and DeCIDe programs through Phase 2 clinical development.

MRF clinical trial to examine antigen-specific MS therapy

The Myelin Repair Foundation (MRF) announced today that its research might soon lead into a clinical proof-of-concept trial at the Department of Neuroimmunology and Multiple Sclerosis Research (nims), University Hospital Zürich, Switzerland, and the Institute for Neuroimmunology and Clinical Multiple Sclerosis Research (inims) in Hamburg, Germany.

CB2 receptor involved in regulating impulsive behaviour

A new study lead by the Neuroscience Institute of Alicante reveals how manipulating the endocannabinoid system can modulate high levels of impulsivity. This is the main problem in psychiatric illnesses such a schizophrenia, bipolar disorder and substance abuse.

Daylight-saving time may increase risk of heart attack

Daylight-saving time this year begins March 11, and while we all might look forward to another hour of sunshine a University of Alabama at Birmingham expert says the time change is not necessarily good for your health.
