Research reveals how RNA elements control cleavage activity of DICER enzyme in pre-miRNA and shRNAs

A research team led by scientists from the Hong Kong University of Science and Technology has revealed how secondary structure RNA elements control the cleavage activity of the DICER enzyme in both pre-miRNA and short-hairpin RNAs, improving the understanding of the DICER cleavage mechanism and providing a foundation for the design of accurate and efficient short-hairpin RNAs for gene-silencing.

Exceptional research recordings display RNA switching “on” and “off”

RNA switches (also known as riboswitches) control which genes are turned “on” and “off”, much like a light switch. Although this appears to be a straightforward process, biologists have been astonished by the inner workings of these switches for decades.

New method helps distinguish bacterial DNA from human and other non-bacterial cells

For decades, a small group of cutting-edge medical researchers have been studying a biochemical, DNA tagging system, which switches genes on or off. Many have studied it in bacteria and now some have seen signs of it in, plants, flies, and even human brain tumors.
