Cellular RNA as a Key Modulator of Mitochondrial Antiviral Signaling

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 are part of the intricate coordination of immune responses against virus invasion.

Engineering Yeast Promoters for Biologic Manufacturing

When introducing genes into yeast to make it produce drugs and other useful substances, it is also necessary to reliably switch the production on or off. A Kobe University team found three gene regulation design principles that provide a flexible guideline for the effective control of microbiological production.
