The new test analyzes RNA molecules in the bloodstream. This type of RNA is called cell-free RNA because the tiny molecules no longer inhabit a cell. There are always fragments of both DNA and RNA ...

Stanford Medicine researchers have developed a blood test capable of detecting cancers, the ways cancer resists treatments and tissue injury caused by non-cancerous conditions. The new test analyzes ...

The crystal structure of a large portion of the E. coli Ffh M domain bound to a 49 nucleotide fragment of 4.5S RNA 1 now demonstrates that the protein and RNA are indeed united in a rather unusual ...

Overview of RNA repair – There is an emerging appreciation of the existence of “RNA repair” pathways that rely on RNA ligases to maintain or manipulate RNA structure in response to purposeful RNA ...

This so-called cell free DNA can be used to identify cancer at very early stages. In a breakthrough, scientists have now developed a method for detecting small amounts of cell-free RNA. When a cell is ...

The new test, which measures levels of certain RNA fragments in the blood, depends on a striking but powerful biological phenomenon. It targets transfer RNA fragments (tRFs)—tiny molecules that ...
