The amazing travels of small RNAs

In most organisms, small bits of RNA play a key role in gene regulation by silencing gene expression. They do this by targeting and docking onto complementary sequences of gene transcripts (also RNA molecules), which stop ...

High-tech gel aids delivery of drugs

Drugs that help prevent the formation of unwanted or harmful proteins are currently being developed to treat a number of diseases, including cancer. The drugs are based on small interfering RNA, or siRNA, which are pieces ...

New nanomedicine slips through the cracks

In a recent study in mice, researchers found a way to deliver specific drugs to parts of the body that are exceptionally difficult to access. Their Y-shaped block catiomer (YBC) binds with certain therapeutic materials forming ...

Green tea compound helps siRNA slip inside cells

Drinking green tea has been linked to health benefits ranging from cardiovascular disease prevention to weight loss. Although many of these claims still need to be verified in the clinic, an antioxidant in green tea called ...

Shining a light on gene regulation

Cancer treatments—from radiation to surgery to chemotherapy—are designed to remove or kill cancerous cells, but healthy cells often become collateral damage in the process. What if you could use lasers to pinpoint the ...

Self-assembled nanostructures hit their target

A tiny therapeutic delivery system that can control the body's ability to manufacture proteins has been developed by Saudi Arabia's King Abdullah University of Science and Technology (KAUST) researchers.
