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.

Liver alterations associated with MASLD can directly affect the brain and behavior

A multidisciplinary research team has discovered that liver alterations associated with metabolic dysfunction-associated fatty liver disease (MASLD) can directly cause cognitive and neurological impairments, and that these effects can be reversed by a therapy exclusively targeting the liver.

Harnessing extracellular vesicles for targeted lung cancer treatment

In the quest for more targeted lung cancer treatments, a researcher at the University of Missouri thinks the solution may lie in tiny bubble-shaped packages that cells use to talk to each other.

What happens when microplastics reach the testes? Study shows autophagy and cell loss

Researchers found that microplastics from everyday plastic tableware accumulate in human semen and, although not linked to semen quality in the full cohort, were associated with altered sperm parameters in specific subgroups. Experimental models confirmed that 50 nm polystyrene particles trigger autophagy and apoptosis via the FOXA1/MAP3K1/p38 pathway, impairing sperm structure and function.
