Sepsis-induced long-term muscle weakness was reproduced using a refined murine model, which was accompanied by mitochondrial dysfunction in the absence of sustained atrophy, suggesting the promise of mitochondria-targeted post-sepsis therapies.
The polarity protein crumbs controls apical secretion and the architecture of the apical domain by modulating PI(4,5)P2 levels and the organization of apical Rab6-, Rab11-, and Rab30-dependent trafficking.
An ensemble of the ubiquitin-activating enzyme UBA6 and ubiquitin-conjugating enzyme/ubiquitin-ligase BIRC6 mediates ubiquitination of LC3, targeting the latter for proteasomal degradation and thus attenuating autophagic degradation of cellular substrates.
Cellularization in Sphaeroforma arctica generates a self-organized structure that morphologically resembles an epithelium, and is associated with tightly regulated expression of cell adhesion pathways.
Heme accumulation is toxic, but deficiency of the heme transporter HRG1/SLC48A1 causes heme sequestration and crystallization into hemozoin within enlarged lysosomes of macrophages, thereby conferring heme tolerance to mammals.
