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 ...

Thanks to increasingly efficient and affordable gene sequencing technologies, we can now chart our genetic blueprint in unprecedented detail. But what does each gene do? Of the roughly 20,000 genes ...

Feb. 20, 2025 -- Genetic testing can be both illuminating and intimidating. What exactly is genetic testing, and who might benefit most? We spoke with Huma Q. Rana MD, MPH, Clinical Director of the ...

Definition: Gene expression is the process by which a cell turns the information in a gene into a functional product, such as an RNA molecule or a protein. In simple terms: gene expression is how a ...

The United States Food and Drug Administration has just approved the first-ever clinical trial that uses CRISPR-Cas13 RNA editing. Its aim is to treat an eye disease called wet age-related macular ...

In the 1990s, Lee Sweeney, a physiologist at the University of Pennsylvania, demonstrated that inserting the gene encoding insulin-like growth factor 1 (IGF-1) into the muscle cells of mice increased ...
