Diagram illustrating the role of miRNAs in the rhizosphere. Whole plants are shown growing in situ with annotations to indicate the role of miRNAs in pathogen resistance, nodule formation and abiotic stressors.

Researchers hit the target: they transport #microRNAs against #MuscularDystrophy to muscle stem cells using nanoparticles.

🎯 Treated mice showed improved muscle strength.

Diagram to illustrate that--when challenged by the fungal pathogen Sclerotinia sclerotiorum--rice secretes microRNAs like Os-miR169y which targets and suppresses the pathogen ribosomal protein gene SsRPL19, impairing protein synthesis in the pathogen and suppressing pathogen growth and pathogenicity.

#microRNAs slow translating #ribosomes to prevent protein #misfolding in eukaryotes
Hiroaki Sako, Tadashi Yamamoto and colleagues
The unusual presence of #miRNAs targeting protein-coding sequences is shown to influence ribosome speed, thereby allowing time for accurate #polypeptide folding during protein translation.
