Human cells repair RNA breaks induced by a programmable CRISPR system, paving the way for temporary treatments for genetic diseases.

RNA editing

Infographic showing endogenous adenosine enzymes acting on RNA (ADARs) edit genetic material in the cell by attaching to naturally occurring double-stranded RNAs, including mRNAs, and switching out A bases with I bases (left). Therapeutic RNA editing platforms based on this mechanism fall into one of two categories: either they use engineered enzymes, which generally consist of the editing part of the ADAR enzyme attached to another protein such as Cas13 that boosts specificity, alongside a guide RNA that targets the enzyme to the desired location (middle); or they consist of a guide RNA alone, which recruits an endogenous ADAR to edit the target sequence (right).

Image of a woman with her hands across her stomach. She has a look of discomfort on her face. There is a blown up image of her stomach next to her and it has colorful butterflies and gut bacteria all swarming within the gut.

Why Do We Feel Butterflies in the Stomach?

These fluttering sensations are the brain’s reaction to certain emotions, which can be amplified or soothed by the gut’s own “bugs".
