Silence the gene, save the cell: RNA interference as promising therapy for ALS

Scientists at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have used RNA interference in transgenic mice to silence a mutated gene that causes inherited cases of amytrophic lateral sclerosis (ALS), substantially delaying both the onset and the progression rate of the fatal motor neuron disease. Their results will be published in the April issue of Nature Medicine, and in the...

Used in a new way, RNA interference permanently silences key breast cancer gene

In laboratory mouse experiments, researchers at The University of Texas M. D. Anderson Cancer Center have developed a way to use RNA interference (RNAi) so that it permanently hampers breast cancer development. The technique permanently silences activated STAT3, a crucial gene found in some human breast tumors, thus reducing the cancer's ability to become invasive. The study, presented at...

Restoring silenced suppressor gene kills lung-cancer cells

A new study suggests that restoring a gene often silenced in lung cancer causes the cells to self-destruct. The findings could lead to a new strategy for treating the disease. The research focused on a gene known as WWOX, which is lost or silenced in a large majority of lung cancers, and in cancers of the breast, ovary, prostate, bladder, esophagus and pancreas. The work was led by scient...

Tool developed to silence genes in specific tissues using RNAi

Researchers at The University of Texas M. D. Anderson Cancer Center say they have jumped a significant hurdle in the use of RNA interference (RNAi), believed by many to be the ultimate tool to both decode the function of individual genes in the human genome and to treat disease. Reporting in the journal Genes and Development, investigators have developed a simple way to use the RNAi appro...

Silence of the amoebae

Freedom of expression is great, but silence is golden ?at least when it comes to amoebae, which are intestine-dwelling parasites that cause life-threatening dysentery in many parts of the world. Three years ago, scientists at the Weizmann Institute accidentally discovered a way to silence the expression of a key amoebic gene, one which codes for a toxic protein that kills human intestinal cells i...

Fluorescently Labeling Long dsRNA with the Silencer siRNA Labeling Kit

Although the <A href="http://www.ambion.com/catalog/CatNum.php?1632"> siRNA Labeling Kits were developed for labeling siRNA, they can be readily adapted for labeling long dsRNA. The following protocol can be used for this application. See "<A href="#visualizing">Visualizing In...

Silencer Validated siRNAs

Silencer Validated siRNAs are single siRNA duplexes that have been verified by real-time RT-PCR to reduce the expression of a number of important human genes. The cut-off for siRNA validation is a >70% reduction in target gene expression 48 hours post-transfection, though the average reduction in target gene expression in the inital set...

pSilencer 4.1-CMV: Versatile Vectors for Expression of siRNA, miRNA, and mRNA

4.1-CMV plasmid vectors are designed for long-term gene silencing experiments in a broad range of cell lines. The vectors carry an RNA polymerase II-type CMV promoter (human cytomegalovirus immediate-early promoter) and an optimized SV40...

Selecting siRNA Sequences to Incorporate into the pSilencer Vectors

The first step in preparing a plasmid for siRNA experiments is to identify target sequences in the gene of interest that are susceptible to siRNA-induced degradation. We have found that a little more than half of the siRNAs provide at least a 50% reduction in target mRNA levels and approximately 1 out of 4 siRNAs...

Australian Scientists 'Silence' Cancer Gene

This new treatment claims to treat the cancer by 'gene silencing.' This process apparently turns off a single gene in a cancer cell responsible for the continued development and spread of the cancer. This means that the other genes // are left unharmed. If successful, this new method promises to beat the conventional methods of treating cancer which include radiation and chemotherapy. These two t...

Silence Can Be Heard

Scientist proved that the brain is always alert even if there is no sound (silence). The brain is activated in people when they are listening out for a sound. Pierre Fonlupt and Julien Voisin conducted the research at Inserm, France's national research institute. He studied the brain activity of 11patients who were at rest with the help of Magnetic Resonance Imaging. // It showed that...

Silence Puts Comfort For Digestive Syndrome

Irritable bowel syndrome, by which 15% of Americans were suffered, was caused by distinctly personal habits and when medication doesn't help, there's often little left// to do but to suffer in silence. Others like constipation, bloating, diarrhea and gas, flatulence make their lives miserable, limiting some of their day-to-day activities. Researches believe that the most basic of treatm...

Commonplace Sugar Compound Silences Seizures

Though in clinical use for decades, a small, sweet-tasting compound is revealing a startling new face as a potential cure for epilepsy.// 2-deoxy-glucose, or 2DG, has long been used in radio labeling, medical scanning and cancer imaging studies in humans. But now, researchers at the University of Wisconsin-Madison have found the substance also blocks the onset of epileptic seizures in...

Intervention Needed to Break 'Silence' on Reproductive Health

There is "enormous silence" in India around adolescent sexual and reproductive health issues, and this can be overcome through involvement of parents, in-laws, spouses// and elders, says a new report by the International Center for Research on Women (ICRW) and partners. More than half the population in India is younger than 25, and many adolescents, particularly unmarried girls, suff...
