Gut feelings: microRNAs tune protein quality control and ageing to odours

A new study in C. elegans identifies a microRNA-dependent mechanism that enables olfactory neurons to rapidly regulate protein degradation in the intestine and therefore organismal ageing.

    In the version of the article originally published, the study by Finger et al. was incorrectly described in one sentence in the third paragraph as implicating the microRNA mir-73 in the regulation of proteostasis; mir-71 was the correct microRNA. The error has been corrected in the HTML and PDF versions of the article.
