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.

Young mouse plasma found to reverse aging in older mice

Researchers demonstrate that small extracellular vesicles (sEVs) from young mice plasma can reverse aging effects in older mice by enhancing mitochondrial function and energy metabolism.

New model pinpoints drug interactions in the digestive tract

Any drug that is taken orally must pass through the lining of the digestive tract. Transporter proteins found on cells that line the GI tract help with this process, but for many drugs, it's unknown which of those transporters they use to exit the digestive tract.

New insights into the role of liver progenitor cells in liver cancer initiation

Primary liver cancers ranked as the sixth most commonly diagnosed cancers and the third leading cause of cancer-related death in 2020. Among all primary liver cancers, HCC is the most common cancer, accounting for more than 80% of cases with a 5-year survival rate of less than 10% in Western countries.
