The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...

In 1998, scientists discovered that petunias, nematodes, fruit flies, mice, and even humans use a built-in cellular mechanism to protect their genome (set of genes) from attacks by viruses. Normally, ...

Researchers have catalogued thousands of sites in the brain where RNA is modified throughout the human lifespan in a process known as adenosine-to-inosine (A-to-I) editing, offering important new ...

University of Connecticut Health Center scientist, Robert Reenan, has uncovered new rules of RNA recoding--a genetic editing method cells use to expand the number of proteins assembled from a single ...

Genes provide the instructions that cells use to produce, or synthesize, proteins, which are necessary for the proper functioning of an organism. Protein synthesis from genes occurs in two basic steps ...

Researchers have discovered RNA mechanisms that may lead to more effective, durable and targeted treatments for conditions like high cholesterol, liver diseases and cancers. RNA interference (RNAi) ...

Insects and plants have an important ancient defense mechanism that helps them to fight viruses. This is encoded in their DNA. Scientists have long assumed that vertebrates - including humans - also ...

RNA interference regulates the target RNA gene through small pieces of RNA that tend to be between 21-24 nucleotides (nt) long. Small RNAs, such as miRNAs and siRNAs, are essential for animal and ...

Discover six RNAi biotech companies helping to drive momentum in a field that can precisely target disease at its genetic root.
