Elusive human protein outsmarted

A team of researchers is being recognized for devising a new way to study a human protein that long has evaded close scrutiny by scientists investigating its role in the communication of important genetic messages inside a cell's nucleus to workhorse molecules found elsewhere.

Scientists discover a new family of giant virus

After Mimivirus, Mamavirus and the virophage, the group of giant viruses now has a new member called Marseillevirus. Discovered in an amoeba by the team led by Didier Raoult at the Unité de Recherche sur les Maladies Infectieuses et Tropicales Emergentes research group (CNRS/Université Aix-Marseille 2), a description of this new virus was published this week on the website of the Proceedings of the National Academy of Sciences (PNAS).

Successful RNA interference to turn off multiple genes raises hope for new liver disease treatments

Researchers at MIT and Alnylam Pharmaceuticals report this week that they have successfully used RNA interference to turn off multiple genes in the livers of mice, an advance that could lead to new treatments for diseases of the liver and other organs.

Grant of $2 million awarded to understand PIGD in Parkinson's disease

The Michael J. Fox Foundation for Parkinson's Research has awarded a total of $2 million to five research teams carrying out clinical studies to refine understanding of postural instability and gait disturbances (PIGD) in Parkinson's disease, and help speed the development of urgently needed treatments.

IKK phosphorylate: A double-edged sword in Huntington's disease

The kinase IKK phosphorylates the protein mutated in Huntington's disease to promote its removal and neuron survival, but IKK may be a double-edged sword that increases neurotoxicity in later stages of the disease. The study, led by researchers from the University of California, Irvine, will be published online December 21 in the Journal of Cell Biology (www.jcb.org).

Researchers determine structures of two enzymes that customize histones

Researchers at Emory University School of Medicine have determined the structures of two enzymes that customize histones, the spool-like proteins around which DNA coils inside the cell.

Influence of key transcription factor is less widespread than thought and varies over time

For decades, science texts have told a simple and straightforward story about a particular protein-a transcription factor-that helps the embryo of the fruit fly, Drosophila melanogaster, pattern tissues in a manner that depends on the levels of this factor within individual cells.

Genes work together by huddling in clusters inside nucleus, research reveals

Research from the Babraham Institute has revealed for the first time that genes work together by huddling in clusters inside the nucleus - the information centre of a cell. These findings, published in the online edition of the journal Nature Genetics, represent a paradigm shift in our understanding of how the genome is spatially organised in relation to gene expression.

RORalpha protein revealed as an essential regulator of inflammatory factors

How do the brain cells called astrocytes ensure the protection of neurons? By studying the protagonists in the protection and satisfactory functioning of neurons, scientists at the Laboratoire Neurobiologie des Processus Adaptatifs (CNRS/UPMC) have found a mechanism that clarifies the role of astrocytes.

Rice, TMC team wins stimulus funds for nanoparticle standardization

One of the promises of nanomedicine is the design of tiny particles that can home in on diseased cells and get inside them. Nanoparticles can carry drugs into cells and tag cells for MRI and other diagnostic tests; and they may eventually even enter a cell's nucleus to repair damaged genes. Unfortunately, designing them involves as much luck as engineering.

Xanthohumol compound may aid in preventing prostate cancer

The natural compound xanthohumol blocks the effects of the male hormone testosterone, therefore aiding in the prevention of prostate cancer.

Applied Spine Technologies: Two Stabilimax surgeries performed in South Africa

Applied Spine Technologies announced today the first two Stabilimax surgeries performed outside of the United States. The surgeries were performed in Johannesburg, South Africa, by Ajay Maharaj, MD, at Sunninghill Hospital. The Stabilimax Dynamic Spine System is currently part of an IDE multi-center, randomized, controlled clinical trial in the U.S.

Gene positions may offer a new method of cancer diagnosis

Certain genes switch their nuclear position in tumor cells, offering a potential new method of diagnosing cancer, say researchers from the National Cancer Institute. The study by Meaburn et al. will be published online December 7, 2009 (www.jcb.org) and in the December 14, 2009 print issue of the Journal of Cell Biology (JCB).

Social isolation and stress can raise breast cancer risk

Social isolation and related stress could contribute to human breast cancer susceptibility, research from a rat model designed at the University of Chicago to identify environmental mechanisms contributing to cancer risk shows.

DBS therapy offers hope for epilepsy patients

Long-term data from an investigational study of Deep Brain Stimulation (DBS) Therapy for Epilepsy was released this week by Medtronic, Inc. (NYSE:MDT) at the American Epilepsy Society Meeting (AES) in Boston.

Discovery of cell fibrous structure may provide clues to diagnose and treat medical disorders

Researchers from the Johns Hopkins Engineering in Oncology Center have shown that in healthy cells, a bundled "cap" of thread-like fibers holds the cell's nucleus, its genetic storehouse, in its proper place.

Protein ERK oscillates between two major compartments in breast tissue cells

Time-lapsed video of individual breast tissue cells reveals a never-before-seen event in the life of a cell: a protein that cycles between two major compartments in the cell. The results give researchers a more complete view of the internal signals that cause breast tissue cells to grow, events that go awry in cancer and are targets of drug development.

Scientists provide the first comprehensive picture of minimal cell

What are the bare essentials of life, the indispensable ingredients required to produce a cell that can survive on its own? Can we describe the molecular anatomy of a cell, and understand how an entire organism functions as a system? These are just some of the questions that scientists in a partnership between the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, and the Centre de Regulacio Genòmica (CRG) in Barcelona, Spain, set out to address.

Wnt and EGFR signaling pathways interact to promote tumor cell invasion and metastasis

Two signaling pathways essential to normal human development - the Wnt/Wingless (Wnt) and epidermal growth factor receptor (EGFR) pathways - interact in ways that can promote tumor cell invasion and metastasis, researchers from The University of Texas M. D. Anderson Cancer Center report in the Nov. 25 issue of Molecular Cell.

Image of a water flea wins top prize in the 2009 Olympus BioScapes Digital Imaging Competition

A glowing, eerily beautiful image of a water flea with its radiant green "crown of thorns" took top prize in the 2009 Olympus BioScapes Digital Imaging Competition®, the world's foremost forum for showcasing microscope photos and movies of life science subjects. Dr. Jan Michels, a zoologist at the University of Albrecht, Kiel, Germany, took top honors for the image of a water flea, with its defensive "crown of thorns" to protect it against predators. The image reveals not only the exoskeleton, but also interior detail down to the nuclei within its cells, seen as tiny, glowing blue dots. This
