siRNA News and Research

RSS

Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded RNA molecules, 20-25 nucleotides in length, that play a variety of roles in biology. Most notably, siRNA is involved in the RNA interference (RNAi) pathway, where it interferes with the expression of a specific gene. In addition to their role in the RNAi pathway, siRNAs also act in RNAi-related pathways, e.g., as an antiviral mechanism or in shaping the chromatin structure of a genome; the complexity of these pathways is only now being elucidated.

Using spherical nucleic acids to track and treat disease

Spherical nucleic acids are structures that are made by taking a nanoparticle template and using chemistry to arrange short strands of DNA or RNA on the surface of those particles. The spherical core of the nanoparticle creates a spherical arrangement of DNA or RNA, similar to tiny little balls of nucleic acids.

Glowing mice could mark major step forward for new gene therapy

Timothy Blake, a postdoctoral fellow in the Waymouth lab, was hard at work on a fantastical interdisciplinary experiment. He and his fellow researchers were refining compounds that would carry instructions for assembling the protein that makes fireflies light up and deliver them into the cells of an anesthetized mouse. If their technique worked, the mouse would glow in the dark.

Overcoming gene silencing barriers to target neurological conditions: an interview with Dr Errol de Souza

Many gene mutations that cause neurological disorders have been identified. For example, in a rare neurological disorder such as Huntington’s disease, an autosomal dominant mutation through expansion of CAG (cytosine-adenine-guanine) triplet repeats in the gene coding for the Huntingtin protein results in abnormal protein production.
