Epigenetic alterations may play an important role in autism

Scientists at the University of Massachusetts Medical School are the first to map epigenetic changes in neurons from the brains of individuals with autism, providing empirical evidence that epigenetic alterations-changes in gene expression caused by mechanisms other than changes in the underlying DNA sequence-may play an important role in the disease.

X-ray crystallography identifies structure of apoA-I molecule

Using a sophisticated technique of x-ray crystallography, researchers Xiaohu Mei, PhD, and David Atkinson, PhD, from Boston University School of Medicine (BUSM) have for the first time obtained an "image" of the structure and the precise arrangement of the atoms in a truncated form of the apolipoprotein A-I (apoA-I) molecule.

'Medicine that grows' confronts antibiotics resistance

It's been called "the trots," "Montezuma's Revenge," "the runs" and worse. But no matter the name, when it strikes, victims wish for a medicine that could go straight to the offending bacteria to quickly knock it dead.

IP-K and Sanofi form new HBV research collaboration

One of the most common and serious infectious diseases, Hepatitis B, is to be targeted in a new collaborative venture between the internationally-renowned translational research institute, Institut Pasteur Korea (IP-K), and the Korean arm of the leading global healthcare company, Sanofi-Aventis Korea. The goal is to develop and validate a high throughput assay to screen IP-K's chemical libraries for novel compounds that can be developed as new drugs.

Scientists identify distinct tobacco transporter for nicotine metabolism

A team of Virginia Tech and Purdue University scientists have identified a distinct transporter used by tobacco plant cells for nicotine metabolism. The research appears in the Oct. 17 online before print issue of the Proceedings of the National Academy of Sciences (PNAS) in the article, "A tobacco nicotine uptake permease effects alkaloid metabolism."

TERE1 gene mutation also contributes to invasive bladder cancer

Research conducted by Dr. Jayne S. Weiss, Professor and Chair of Ophthalmology at LSU Health Sciences Center New Orleans, and colleagues has found that a defect in a gene involved in a rare disease of the cornea also contributes to the progression of invasive bladder cancer.

Elevated body temperature helps certain types of immune cells to work better

With cold and flu season almost here, the next time you're sick, think twice before taking something for your fever. That's because scientists have found more evidence that elevated body temperature helps certain types of immune cells to work better.

Ultra-sensitive techniques for early detection of breast cancer

A team of scientists at Tufts University will develop ultra-sensitive techniques at the single-molecule and single-cell levels designed to detect breast cancer earlier, and treat it with greater precision, through a $6.6 million Innovator Award from the Department of Defense Breast Cancer Research Program made to Tufts chemist David R. Walt, Ph.D.

Researchers identify FMRP protein as key player in RNA editing

The most common form of heritable cognitive impairment is Fragile X Syndrome, caused by mutation or malfunction of the FMR1 gene. Loss of FMR1 function is also the most common genetic cause of autism. Understanding how this gene works is vital to finding new treatments to help Fragile X patients and others.

Research focuses on JQ1 molecule that tricks NUT midline carcinoma cancer cells

NUT midline carcinoma (NMC) is a cancer without a cure, and one that affects all age groups. NMC is a rapid-growth disease with an average survival time of four and a half months after diagnosis, making the development of clinical trials for potential therapies or cures for this cancer difficult, to say the least.

Scientists identify nicotinamidase enzyme as new drug target for Leishmaniasis

IRD scientist and their research partners recently identified the key role of nicotinamidase, an enzyme in the parasite Leishmania, essential for its survival but which does not exist in humans. The pathogen is incapable of developing in mammals In the absence of this enzyme. Specific targeting of this enzyme could lead to more effective ways of controlling this neglected tropical disease.

Scientists describe how protein acts as courier in cell signaling pathways

Normal development, from fertilized egg to adult organism, depends on each cell receiving proper instructions from its environment. In response to such incoming information, receptors on a cell's surface send signals to the nucleus that tweak gene expression and control cellular function.

AD risk genes impact Aβ toxicity in neurons

In a development that sheds new light on the pathology of Alzheimer's disease (AD), a team of Whitehead Institute scientists has identified connections between genetic risk factors for the disease and the effects of a peptide toxic to nerve cells in the brains of AD patients.

Study provides details on genetics behind many metabolic diseases

In what is so far the largest investigation of its kind, researchers uncovered a wide range of new insights about common diseases and how they are affected by differences between two persons' genes. The results from this study could lead to highly targeted, individualized therapies.

NIH awards DNASU $6.5M grant to expand Protein Structure Initiative-Materials Repository

Arizona State University's Biodesign Institute- is home to a rich trove of biological material. Known as DNASU, this growing storehouse-a sort of genetic Library of Congress-holds over 147,000 plasmids, (circular DNA samples that can be used to produce individual proteins), as well as full genome collections from numerous organisms and proteins associated with many leading human diseases.
