Injuries activate the oral identity-specifying canonical Wnt signaling pathway in Hydra, which can trigger head regeneration in permissive tissue contexts created by the absence of pre-existing organizers.
Proximity labeling-based proteomic strategies applied in zebrafish identify new insights into protein network changes in heart muscle cells during regeneration and implicate Rho A as a target of ErbB2 signaling during zebrafish heart regeneration.
Early postmortem autopsy of COVID-19 patients shows high viral loads and damage of the lung, although extrapulmonary cells demonstrate no injury, they contribute to inflammation, hyper-coagulation, and multiple organ dysfunction.
A computational tool developed to construct three-dimensional anatomical atlases from two-dimensional data generates volumetrically complete and aligned atlases for all stages of development in the Allen Developing Mouse Brain Atlas.
A mutant impaired for ribosome recycling exhibits translational reprogramming wherein strong mRNAs outcompete weak mRNAs, also observed when preinitiation complexes are diminished by eIF2α phosphorylation or 40S ribosomal subunit depletion.
