Genome-wide RNA-seq analysis of single cells of the developing mouse endolymphatic sac reveals its molecular-cellular architecture and a model for salt and fluid absorption required for acquisition of normal inner ear structure and function.

TBX5-loss associated cardiomyocyte ectopy and atrial fibrillation is prevented by augmentation of SERCA2 activity, establishing a mechanism underlying the genetic basis for a Ca2+-dependent pathway for AF risk.

Identification of Cl−-induced folding advances the field’s understanding of prestin’s unique voltage-sensing mechanism and its involvement in mammalian hearing sensation.

Imaging studies of connexin-coupled networks of colorectal cancer cells reveal that cells carrying a genetic defect in an essential metabolic pathway can be rescued by diffusive exchange with neighboring wild-type cells via gap junctions, particularly Cx26, thereby evading negative selection.
Globotriaosylcermide directly impacts neuronal integrity and ion channel function as potential mechanism underlying small fiber pathology in Fabry disease.

Colorectal tumors down-regulate the mitochondrial Na+/Ca2+/Li+ exchanger (NCLX) to alter mitochondrial Ca2+ signaling and initiate transcriptional and metabolic reprogramming that drives tumor chemo-resistance and metastasis.
Functional and computational studies reveal that the allosteric inhibition mechanism is conserved between glutamate and neutral amino acid transporters of the SLC1 family, and identify a novel allosteric inhibitor.

The high-resolution x-ray structure of an asymmetrical SeCitS dimer, present in the inward- and outward-facing state, provides a complete mechanism of substrate and ion translocation in a sodium-dependent symporter.
Acidification and salt, which are two major stresses caused by environmental changes, swiftly and drastically alter the microtubule system in green algae and likely many other organisms.

Whether deforming cells behave as elastic balls (deforming at constant volume) or as sponges (loosing volume as they deform) depends on how fast they change their shape, because the cell volume depends on the tension of the plasma membrane.
