Solubility phase transition of maternal RNAs during vertebrate oocyte-to-embryo transition.

The oocyte-to-embryo transition (OET) is regulated by maternal products stored in the oocyte cytoplasm, independent of transcription. How maternal products are precisely remodeled to dictate the OET remains largely unclear. In this work, we discover the dynamic solubility phase transition of maternal RNAs during Xenopus OET.

Phase transition of maternal RNAs during vertebrate oocyte-to-embryo transition.

The oocyte-to-embryo transition (OET) is regulated by maternal products stored in the oocyte cytoplasm, independent of transcription. How maternal products are precisely remodeled to dictate the OET remains an open question. In this work, we discover the dynamic phase transition of maternal RNAs during OET.

Localized Proteolysis for the Construction of Intracellular Asymmetry in .

Protein-level regulations have gained importance in building synthetic circuits, as they offer a potential advantage in the speed of operation compared to gene regulation circuits. In nature, localized protein degradation is prevalent in polarizing cellular signaling. We, therefore, set out to systematically investigate whether localized proteolysis can be employed to construct intracellular asymmetry in .

Temperature rise curtails activity period predicted for a winter-active forest lizard, Scincella formosensis, from subtropical areas in Taiwan.

1. Temperature rise due to climate change affects seasonal activity times, leading to a discordance of phenology among species and changing the strength of interaction between species. Understanding how temperature changes will affect the length of a species' activity period is essential in order to forecast its response to climate warming.
