Communication usually applies feedback loop-based filters and amplifiers to ensure undistorted delivery of messages. Such an amplifier acts during Drosophila melanogaster midoogenesis, when oskar messenger ribonucleic acid (mRNA) anchoring depends on its own locally translated protein product. We find that the motor regulator Klar β mediates a gain-control process that ...

In skeletal muscle, autophagy is activated in multiple physiological and pathological conditions, notably through the transcriptional regulation of autophagy-related genes by FoxO3. However, recent evidence suggests that autophagy could be also regulated by post-transcriptional mechanisms. The purpose of the study was therefore to determine the temporal regulation of transcriptional and ...
