Researchers discover genomic causes of acute lymphoblastic leukemia relapse

Scientists at St. Jude Children's Research Hospital have identified distinctive genetic changes in the cancer cells of children with acute lymphoblastic leukemia (ALL) that cause relapse.

Research identifies cell receptor as target for anti-inflammatory immune response

Cell reception. By comparing normal mice (left) with mice that are genetically engineered to lack certain receptors in their spleen (right), scientists have shown SIGNR1 receptors (blue) are required to facilitate an anti-inflammatory action.

Breakthrough for dialysis patients

Suffering from end-stage renal disease (ESRD), a growing number of patients at the Centre hospitalier de l'Université de Montréal (CHUM), have become the beneficiaries of a North American breakthrough: high efficacy hemodiafiltration (HDF).

Discovery of new way in which epigenetic information is inherited

Hereditary information flows from parents to offspring not just through DNA but also through the millions of proteins and other molecules that cling to it.

First study showing how protein fine-tunes the heart

Dr Andrew Whitten, Dr Cy Jeffries and Professor Jill Trewhella, from the School of Molecular and Microbial Biosciences, University of Sydney, with Samantha Harris, from the University of California, USA, have the first data showing how a protein in heart muscle cells works to maintain regular heart function.

Yale researchers find molecule that may help regulate how much animals and people eat

In the battle against obesity, Yale University researchers may have discovered a new weapon - a naturally occurring molecule secreted by the gut that makes rats and mice less hungry after fatty meals.

Researchers provide new evidence that aging can be slowed

New evidence may explain why it is that we lose not only our youthful looks, but also our youthful pattern of gene activity with age.

Noninvasive test for urine protein detects kidney dysfunction in transplant patients

A noninvasive test that analyzes proteins in the urine can correctly identify patients whose transplanted kidneys are failing, according to a study appearing in the February 2009 issue of the Journal of the American Society Nephrology (JASN).

Study compares strategies for BK virus nephropathy

For kidney transplant recipients with a serious complication called BK virus-associated nephropathy (BKVAN), promptly cutting back on anti-rejection drugs reduces the risk of losing the kidney (graft loss), according to a report in the November Clinical Journal of the American Society of Nephrology (CJASN).

Researchers uncover a critical link between taste and body weight

Obesity gradually numbs the taste sensation of rats to sweet foods and drives them to consume larger and ever-sweeter meals, according to neuroscientists.

Researchers provide new insight into adaptive ability of cells

The Stowers Institute's Rong Li Lab has published findings that shed light on the ability of cells to adapt to disruptions to their basic division machineries - findings that may help explain how cancer cells elude the body's natural defense mechanisms or chemotherapy treatment.

Researchers identify a potentially universal mechanism of aging

Like our current financial crisis, the aging process might also be a product excessive deregulation.

Discovery of mechanism linking serotonin with regulation of food intake

Genetic mouse models have provided surprising insight into mechanisms linking serotoninergic compounds with the regulation of feeding behavior and body weight.

NSF grant puts talented undergraduates into research labs

Thirty undergraduate college students from around the nation will have the chance to spend a summer getting paid to explore the world of biological research, thanks to the efforts of scientists at the University of Rochester's Medical Center and River Campus.

Mouse model of prion disease mimics diverse symptoms of human disorder

A comprehensive mouse model of inherited prion disease exhibits cognitive, motor, and neurophysiological deficits that bear a striking resemblance to the symptoms experienced by patients with the human version of "mad cow disease," Creutzfeldt-Jakob disease (CJD).

Researchers identify molecule that tells your brain your stomach is full

In studies with mice and rats, researchers have found that a chemical messenger called NAPE is made in the small intestine after the animals ate a greasy meal. After eating, NAPE - N-acylphosphatidylethanolamine, a mouthful in itself -- enters the blood and travels to the brain, where it quashes hunger signals.
