Study: microRNAs are Key to Evolution of Complex Octopus Brain

Dec 30, 2022 by News Staff

Octopuses and their cephalopod relatives are exceptionally intelligent invertebrates with a highly complex nervous system that evolved independently from...

Zhou et al. revealed that the miR-183/96/182 cluster has functional impacts on circadian rhythms in mammals; they can modulate circadian systems either by direct targeting of the core clock machinery or through a more indirect mechanism that ultimately feeds into the circadian clock.
