Novel antiviral technology inhibits RSV infection in mice

...antiviral treatment combiningnanoparticle and gene silencing technologies thwarts attacks ofrespiratory syncytial virus (RSV) -- a virus associated with severebronchitis and asthma, an animal study by University of South Floridaresearchers found. The study was reported in the January 2005 issue ofthe journal N...

TEL2 gene cooperates with MYC gene to provoke B-cell lymphomas

...hey succeed in eliminating p53 activity, in effect silencing the command to commit suicide. This situation occurs when increased TEL2 activity reduces the cell's ability to trigger apoptosis in response to relentless prodding by MYC to keep multiplying. As the process of apoptosis becomes sluggish, the populat...

Variation in women's X chromosomes may explain differences among individuals, between sexes

...that the inactivation process resulted in complete silencing of the genes on the second X chromosome, Willard said, in order to leave both sexes with the same activity level, or dosage, of the genes encoded by the X chromosome. Scientists had also implicitly assumed that the X chromosomes in all women would be...

50-year-old Mystery Solved: Protein Tags Regulate Key Ion Channel

...." The problem was that some hidden mechanism was silencing the channel, plugging the pipeline, but no known method of channel regulation seemed to be involved. Goldstein and colleagues began to suspect sumoylation [SUE-mow-e-LAY-shun]. In this process, an enzyme attaches a small peptide called SUMO (for sma...

UCSD-Salk Team Show Protein’s Gene-Silencing Role In Development of Nervous System

...uired for maintenance of neural stem cells and for silencing expression of neuronal genes in non-nervous system tissues. Published in the January 28, 2005 issue of the journal Science, the study found that the phosphatases, called small carboxyl-terminal domain phosphatases (SCPs) are expressed in almost all ...

Novel gene-silencing nanoparticles shown to inhibit Ewing's sarcoma

A novel delivery system that transports gene silencing nanoparticles into tumor cells has been shown to inhibit Ewing's sarcoma in an animal model of the disease. In this classic "Trojan horse" approach, a protein called transferrin that normally delivers iron into cells is modified to also smuggle into...

Protein helps regulate the genes of embryonic stem cells

...mpact on gene expression - either by activating or silencing a gene. "Diversity is determined by different types of chemical modifications and also by the number of modifications," Montgomery said. "And those modifications are the unit of epigenetic information, just as the DNA sequence is the unit of genetic...

U. Iowa researchers improve Huntington's disease symptoms in mice

...r regarding whether the normal gene is critical by silencing the normal gene in adult brain cells of HD models. Despite the remaining hurdles, Davidson is optimistic about the potential of RNAi to treat HD and similar neurodegenerative diseases. "If the benefit is confirmed in other mouse models of Huntingto...

Gene silencing technique offers new strategy for treating, curing disease

...tly, the researchers also employed RNA itself as a silencing agent. Previous work by other scientists had shown that RNA might be able to target chromosomal DNA, so once Dr. Corey and his team saw that PNAs were working, they decided to try RNA as well. "The RNA is more important because it may reflect the bo...

Molecular steps involved in the creation of gene-silencing microRNAs identified

... directly through to the molecules responsible for silencing genes," says Ramin Shiekhattar, Ph.D., an associate professor at Wistar and senior author on both Nature studies. "The miRNAs provide specificity for those molecules, which do the actual work of gene silencing." Intriguingly, the research also links...

Montreal researchers probe the genetic basis of memory

Now that Sánchez Alvarado and his colleagues have opened the door to understanding regeneration by identif...

How cell suicide protects plants from infection

...ess. Dinesh-Kumar first developed a technique for silencing or inactivating plant genes -- a technique that is now used by several research groups. His group studies the interaction between plants and viruses using tobacco as a model system. They identified and silenced a "pro-survival" gene, BECLIN-1, that ...
