Better RNA interference, inspired by nature

New MIT nanoparticles offer best-ever gene silencing, could help treat liver diseases. Inspired by tiny particles that carry cholesterol through the body, MIT chemical engineers...

New MIT tool speeds gene discovery

Since the completion of the Human Genome Project, which identified nearly 20,000 protein-coding genes, scientists have been trying to decipher the roles of those...

Researchers Discover Innate Virus-killing Power in Mammals

Scientists have a promising new approach to combating deadly human viruses thanks to an educated hunch by University of California, Riverside microbiology professor Shou-Wei...

Protein may be key to new treatment in a childhood cancer

After analyzing hundreds of proteins produced by the DNA of tumor cells, researchers have identified one protein that may be central to a new treatment for the often-fatal childhood cancer neuroblastoma. Oncologists hope to translate the finding int...

MicroRNA-TP53 circuit connected to chronic lymphocytic leukemia

HOUSTON - The interplay between a major tumor-suppressing gene, a truncated chromosome and two sets of microRNAs provides a molecular basis for explaining the less aggressive form of chronic lymphocytic leukemia, an international team of researchers...

Tiny molecules protect from the dangers of sex

DURHAM, N.C. -- Pathogenic fungi have been found to protect themselves against unwanted genetic mutations during sexual reproduction, according to researchers at Duke University Medical Center. A gene-silencing pathway protects the fungal genome fr...

Virtual research institute needed to unlock RNA’s promise

Strasbourg, 11 October 2010 - A Europe-wide network of labs focusing on RNA research is needed to make the most of RNA's high potential for treating a wide range of diseases. The recommendation for this virtual research institute comes from a panel ...

Rice study examines how bacteria acquire immunity

HOUSTON -- (Sept. 15, 2010) -- In a new study this week, Rice University scientists bring the latest tools of computational biology to bear in examining how the processes of natural selection and evolution influence the way bacteria acquire immunity...

Scientists find what type of genes affect longevity

Tracing all the genetic changes that flow from a single mutation, UCSF scientists have identified the kinds of genes and systems in the body that ultimately allow a doubling of lifespan in the roundworm, C. elegans. Humans share many of these genes, and the researchers think the new findings offer clues to increasing human youthfulness and longevity as well.

Researchers silence genes with new approach

Researchers have developed a way to exploit RNA interference for the first time to silence genes in a wide variety of mammalian cells, including embryonic cells. The study will appear in the Feb. 17 edition of Nature Genetics. This new approach allows genes to be switched off by inserting short pieces of ribonucleic acid (RNA) into developing cells. It is currently being used to help researchers uncover the function of the more than 30,000 genes found in humans, as well as in animal models of important diseases.
