Peptides: A new clue on the origins of life

Emory University scientists have discovered that simple peptides can organize into bi-layer membranes. The finding suggests a "missing link" between the pre-biotic Earth's chemical inventory and the organizational scaffolding essential to life.

New study may help design better vaccines for dengue fever

Some of the human immune system's defences against the virus that causes dengue fever actually help the virus to infect more cells, according to new research published today in the journal Science.

The emerging science of epigenetics

Human embryonic stem cells (hESCs) possess remarkable properties of self-renewal and pluripotency, the ability to become almost any kind of cell within the body. And yet they share the same genome or set of genes with lineage-committed cells, cells fated to be or do one thing.

Imprinted genes may be the root cause of gender specific diseases, says study

Pregnancy places competing demands on a mother's physiology: Her body wants to produce a strong healthy baby but not at the expense of her own health. Some of the genes that she passes on to her child therefore try to protect her own body from excessive demands from her child.

Scientists catch new mediators to develop novel treatments for diseases linked to inflammatory processes

Scientists at the University of Pittsburgh School of Medicine went on a molecular fishing trip and netted a catch of new mediators that not only can explain how omega-3 fatty acids reduce inflammation, but also hint at novel treatments for a host of diseases linked to inflammatory processes. Their findings were published today in the online version of Nature Chemical Biology.

Study aims to clarify expression patterns of CD24 in NSCLC

The May edition of the Journal of Thoracic Oncology features a study aimed to clarify expression patterns of a novel cancer biomarker, CD24, in non-small cell lung carcinomas (NSCLC) and to correlate the findings to clinicopathologic variables, such as performance status, age, gender and prognostic significance.

Neuroscientist Snyder presents annual Ellis S. Grollman Lecture at UMB

If a drug was developed to block a key protein linked to the onset of Huntington's Disease, it could have a clear path to the part of the brain most affected by the disease, while not bothering other parts of the brain and body, said distinguished neuroscientist Solomon H. Snyder, MD, to an audience of about 300 students and faculty at the University of Maryland, Baltimore (UMB).

Multistage nanovector system for siRNA delivery lengthens therapeutic effects of ovarian cancer treatment

New research by scientists at The University of Texas Health Science Center at Houston (UTHealth) and The University of Texas M. D. Anderson Cancer Center could make it easier for patients to use a family of promising experimental cancer therapeutics known as small interfering RNA (siRNA).

RayBiotech announces biomarker grant winners

RayBiotech, Inc. has announced the winners of its Biomarker Discovery Pilot Grant program. In total, 18 award recipients were chosen for grants of up to $20,000 each, redeemable for RayBiotech products and services. "By offering these grants," states Dr. Ray (Ruopan) Huang, Founder and President of RayBiotech, "we intend to demonstrate that any researcher with a modest research budget can successfully discover and validate disease-related biomarkers using our antibody arrays."

Researchers to identify rare genetic mutation to produce histamine against TS

A single, very unusual family with Tourette syndrome has led Yale School of Medicine researchers to identify a rare mutation in a gene that is required to produce histamine. The finding provides a new framework to understand many years of data on the role of histamine function in the brain and points to a potentially novel approach to treatment of tics and Tourette.

New research suggests tPA can act as neuroprotectant against stroke

New research on the properties of the clot-busting stroke drug tPA (tissue-type plasminogen activator) suggests that tPA can act as a neuroprotectant and may form the keystone of an adaptive response to a reduction in blood flow.

Scientists use specialized fluorescent protein to study nerve cell activity

Electrical currents are invisible to the naked eye - at least they are when they flow through metal cables. In nerve cells, however, scientists are able to make electrical signals visible. Working with fellow experts from Switzerland and Japan, scientists from the Max Planck Institute for Medical Research in Heidelberg successfully used a specialized fluorescent protein to visualize electrical activity in neurons of living mice.

Acceleron Pharma commences Phase 2 clinical trial of ACE-031 protein therapeutic in DMD patients

Acceleron Pharma, Inc., a biopharmaceutical company developing novel therapeutics that modulate the growth of cells and tissues including muscle, bone, fat, red blood cells and the vasculature, today announced the initiation of a Phase 2 clinical trial with ACE-031 in patients with Duchenne Muscular Dystrophy (DMD), a fatal neuromuscular disease. ACE-031 is an investigational protein therapeutic that builds muscle and increases strength by inhibiting signaling of a cell surface receptor called the activin receptor type IIB (ActRIIB).

Cryo-EM images shed light on virus structure, function

UCLA researchers report in the April 30 edition of the journal Cell that they have imaged a virus structure at a resolution high enough to effectively "see" atoms, the first published instance of imaging biological complexes at such a resolution.
