A microRNA cluster believed to be important for suppressing colon cancer has been found to play a critical role in wound healing in the intestine, UT Southwestern cancer researchers have found. The findings, first discovered in mice and later reproduced in human cells, could provide a fresh avenue for investigating chronic digestive diseases and for potentially repairing damage in these and other disease or injury settings.

Researchers at the University of California, San Diego School of Medicine have successfully targeted T lymphocytes – which play a central role in the body’s immune response – with another type of white blood cell engineered to synthesize and deliver bits of non-coding RNA or microRNA (miRNA).

A small group of immune-regulating molecules, when overproduced even moderately, can trigger the blood cancers known as lymphomas, according to a new study led by scientists from The Scripps Research Institute (TSRI).

One of life’s most basic processes – transcription of the genetic code – resembles road traffic, including traffic jams, accidents and a police force that controls the flow of vehicles. This surprising finding, reported recently by Weizmann Institute researchers in Nature Communications, might facilitate the development of a new generation of drugs for a variety of disorders.

New research shows that a tiny piece of RNA has an essential role in ensuring that embryonic tissue segments form properly.  The study, conducted in chicken embryos, determined that this piece of RNA regulates cyclical gene activity that defines the timing of the formation of tissue segments that later become muscle and vertebrae.

It takes a lot to make a memory. New proteins have to be synthesized, neuron structures altered. While some of these memory-building mechanisms are known, many are not. Some recent studies have indicated that a unique group of molecules called microRNAs, known to control production of proteins in cells, may play a far more important role in memory formation than previously thought.
