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.

Microbes in the guts of carpenter ants could lead to better drugs

Scientists have discovered two key proteins that guide one of the two groups of pathogenic bacteria to make their hardy outer shells -- their defense against the world.

Standard low-dose birth control pill can actually help women conceive

Women who have tried to conceive using in vitro fertilization (IVF) methods are painfully aware that timing is of the essence.

Research to lead to brain tumor therapies

Unique human in vitro model (cell culture) research currently underway at the Peninsula Medical School in the South West of England is set to identify and develop therapies for the treatment of multiple tumours in the brain.

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.
