The long-distance flight of locusts is greatly facilitated by a muscle-abundantly expressed Hif-1α splice variant, which remains active in normoxia and scavenges flight-induced reactive oxygen species by upregulating the expression of DJ-1 (PARK 7).
Prolonged β-adrenergic stimulation causes ryanodine receptor clusters to disperse, drastically altering the frequency and kinetics of Ca2+ release events called ‘Ca2+ sparks’ in a process that is dependent on CaMKII and PKA.
Genetic, proteomic, and structural analyses provide insight into the role of Brl1 during nuclear pore complex biogenesis, suggesting a function in the fusion of outer and inner nuclear membranes.
IL-33 plays an important role in the initiation of labor by leading to stress of the ER via an influx of calcium ions in human uterine smooth muscle cells.

A biophysical model in which kinetochore microtubules nucleate at kinetochores and growth polward along nematic streamlines quantitatively explains kinetochore microtubule lengths, orientations, and spatially varying dynamics in metaphase human spindles.
The phagocytic receptor CED-1 is kept at the appropriate level by E3 ligase trim-21-mediated ubiquitination-proteasomal degradation for apoptotic cell clearance, which is independent of retromer-dependent recycling and lysosomal degradation.
HaloTag becomes resistant to lysosomal proteolysis upon ligand binding, enabling us to measure various types of autophagic flux easily and precisely by using HaloTag-containing reporters for processing assays.
