Study: Kidney cancer growth depends on autophagy

New research at the University of Cincinnati (UC) suggests that kidney cancer growth depends on autophagy, a complex process that can provide cells with nutrients from intracellular sources. Researchers say in certain circumstances autophagy can protect tumor cells from chemotherapy, allowing them to survive for long periods of time in a hidden, dormant, metastatic state.

UCSF scientists assemble high-value genetic resource to help researchers

One of the ultimate ways of understanding what impact any particular gene has in human health or disease is to disrupt it-knocking it down or wiping it out in a worm, fly or mouse and gauging what happens next. Now scientists at the University of California, San Francisco (UCSF) Diabetes Center and the Gladstone Institute for Cardiovascular Disease have assembled a large publicly available resource to help researchers determine the importance of genes in mice and better gauge what roles they might play in disease.

MTR can prevent cell death in patients with TBI

Wake Forest Baptist Medical Center researchers seeking a successful treatment for traumatic brain injury have found that the size and extent of damaged tissue can be reduced by using a new device to prevent cell death.

T-FET biosensor can detect biomolecules at ultra-low concentrations

A new quantum mechanical-based biosensor designed by a team at University of California, Santa Barbara offers tremendous potential for detecting biomolecules at ultra-low concentrations, from instant point-of-care disease diagnostics, to detection of trace substances for forensics and security.

Nurr1 gene plays a fundamental role in neuron survival

Researchers at the Institute of Neurosciences at Universitat Aut-noma de Barcelona (INc-UAB) identified the fundamental role played by the Nurr1 gene in neuron survival associated with synaptic activity. The discovery, published in the Journal of Biological Chemistry, allows scientists to study a new target that could help to understand the relationship between alterations in neural connections, which are known to cause early cognitive deficit, and the neurodegeneration characteristic of Alzheimer's disease.

Lack of mLin41 gene regulator can cause neural tube defects

Researchers at the University of Colorado School of Medicine have found that lack of a specific gene interrupts neural tube closure, a condition that can cause death or paralysis.

Two related enzymes play a key role in development of T-ALL

Columbia University Medical Center (CUMC) scientists have demonstrated that two related enzymes - phosphoinositide-3 kinase (PI3K) gamma and delta - play a key role in the development of T-cell acute lymphoblastic leukemia (T-ALL), a highly aggressive childhood leukemia that is difficult to treat.

Researchers identify 56 genetic variants that influence BMD

Researchers at The Institute for Aging Research at Hebrew SeniorLife, an affiliate of Harvard Medical School, have co-authored the largest meta-analysis of genome-wide association studies of osteoporosis as part of an international consortium and have identified dozens of genetic variants found to be linked to an increased risk of developing osteoporosis and of suffering broken bones.

Abnormal protein accumulation in the brain may lead to onset, severity of Parkinson's

Injection of a small amount of clumped protein triggers a cascade of events leading to a Parkinson's-like disease in mice, according to an article published online this week in the Journal of Experimental Medicine.

Study pinpoints compounds that repress cancer gene’s activity

A research team pursuing one of the most commonly altered genes in cancer has laid a critical foundation for understanding this gene that could point the way toward developing drugs against it. A recent study of cancer genetics pointed to the gene MCL1, which encodes a protein that helps keep cells alive

Immunotherapy may also help elderly cancer patients

Cancer is much more likely in the elderly than the young, and their bodies often are less prepared to fight the disease and the often-toxic side effects of treatment.

Keck Foundation awards UF $1M to study how proteins in cells are made

The Center for NeuroGenetics at the University of Florida has received a competitive $1 million grant from the W.M. Keck Foundation to study a new idea that challenges conventional understanding of how proteins in cells are made, and their impact on inherited diseases.

New drug to detect beta-amyloid plaques may help diagnose AD earlier

Use of a new drug to detect the beta-amyloid plaques in the brain that are hallmark signs of Alzheimer's disease may help doctors diagnose the disease earlier, according to research that will be presented as part of the Emerging Science program (formerly known as Late-Breaking Science) at the American Academy of Neurology's 64th Annual Meeting in New Orleans April 21 to April 28, 2012.

High blood sugar in combination with high insulin levels causes fatty deposits in the heart

The impaired substrate metabolism of diabetes patients is often expressed in an increase in fatty deposits in the cells of the heart muscle. Until now, the exact cause of this was unknown. Now, researchers at the MedUni Vienna in the Division of Endocrinology and Metabolism of MedUni Vienna in cooperation with the MR Centre of Excellence Vienna have shown that high blood sugar in combination with high levels of insulin - not an influx of fats - results in such deposits within a few hours.

Gene function preserved despite structural differences in the DNA

Chloroplasts, the plant cell's green solar power generators, were once living beings in their own right. This changed about one billion years ago, when they were swallowed up but not digested by larger cells. Since then, they have lost much of their autonomy.
