New insights into anti-cancer effects of NSAIDs

Researchers at the National Sun Yat-Sen University and Kaohsiung Medical University, Kaohsiung, Taiwan have revealed a new mechanism by which nonsteroidal anti-inflammatory drugs (NSAIDs) attenuate tumor invasion and metastasis.

Potential new genetic markers for Crohn's disease

What is believed to be the largest study of its kind for the genetic roots of inflammatory bowel diseases has suggested new links to Crohn's Disease as well as further evidence that some people of Jewish descent are more likely to develop it.

Key factor in brain development revealed, offers insight into lissencephaly

In the earliest days of brain development, the brain's first cells - neuroepithelial stem cells - divide continuously, producing a population of cells that eventually evolves into the various cells of the fully formed brain.

Environmental factors linked to development of autoimmune diseases

Scientists working at the MRC National Institute for Medical Research have shown that environmental factors can influence the development of autoimmune diseases like multiple sclerosis.

Anticancer siRNA therapy advances, thanks to nanoparticles

Small pieces of nucleic acid, known as siRNAs (short interfering RNAs), can turn off the production of specific proteins, a property that makes them one of the more promising new classes of anticancer drugs in development. Indeed, at least two siRNA-based anticancer therapies, both delivered to tumors in nanoparticles, have begun human clinical trials. Now, three new reports highlight the progress that researchers are making in developing broadly applicable, nanoparticle-enabled siRNA anticancer therapeutics.

Astrotechnology brings nanoparticle probes into sharper focus

While pondering the challenges of distinguishing one nanosize probe image from another in a mass of hundreds or thousands of nanoprobes, two investigators at Emory University and the Georgia Institute of Technology made an interesting observation. The tiny, clustered dots of light looked a lot like a starry sky on a clear night.

Targeting aggressive breast cancers by putting them to sleep

It is well established that Id1, a gene normally produced only in embryonic development, is reactivated in many 'solid' cancers, or carcinomas.

Study examines association between type of genetic characteristics and cancer

Persons with a certain type of homozygosity (having two identical copies of the same gene, one inherited from each parent), may have a greater predisposition to cancer, according to a study in the March 26 issue of JAMA.

New understanding of how color vision is processed

New York University biologists have mapped the medulla circuitry in fruit flies, setting the stage for subsequent research on how color vision is processed.

Luna discovers nanomedicine prototype aids in the growth of new hair follicles

Scientists at Luna's nanoWorks Division in Danville, VA, have been developing a portfolio of new candidates based on antioxidant nanomaterials which could lead to a platform technology for treating a wide range of diseases. “One of our new nanomedicine prototypes, after only two weeks of treatment, was found to increase the number of hair follicles fourfold in mice which are born genetically hairless,” said Robert Lenk, President of Luna's nanoWorks Division.

REST protein protects embryonic stem cells' versatility and self-renewal

A protein known as REST blocks the expression of a microRNA that prevents embryonic stem cells from reproducing themselves and causes them to differentiate into specific cell types, scientists at The University of Texas M. D. Anderson Cancer Center report in the journal Nature.
