RNA in cells performs an astounding number of functions. Messenger RNA carries the sequences of active genes to cellular machinery that turns it into proteins. And transfer RNA molecules are an ...

Cells move their genetic material from one place to another in the form of RNA. Christoph Burgstedt/Science Photo Library via Getty Images Before 2020, when my friends and acquaintances asked me what ...

Scientists have uncovered a new role for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals ...

A new study has explored the RNA-binding mechanisms of the antiviral protein TRIM25. TRIM25 (green, left) finds its way to the same locations in the cell where a virus (red, middle) replicates. The ...

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered that SARS-CoV-2, the virus that causes ...

Messenger RNA carries genetic information from DNA in the highly protected nucleus out to the rest of the cell, where structures called ribosomes can build proteins according to the DNA blueprint.

BUFFALO, N.Y. — RNA has been in the limelight for its starring role in cutting-edge vaccine technology, but RNA molecules are also key players in the inner workings of cells. This lesser explored RNA ...

A tiny chemical modification commonly found on messenger RNAs plays a surprisingly large role in how cells respond to stress, according to a study led by Weill Cornell Medicine investigators. The ...

The innate immune system is the body's first line of defence against pathogens like bacteria or viruses. TRIM25 is a protein that is important in the innate immune response against RNA viruses, such ...
