Beschreibung: Article Blood supply to the heart is crucial for cardiac function. Here, the authors show that the mitochondrial tryptophanyl-tRNA synthetase, WARS2, drives blood vessel generation in zebrafish and rats and that inhibition of Wars2 diminishes blood vessel growth both within and outside in the heart, suggesting a new target for manipulating angiogenesis.

Beschreibung: Article Alveoli are the lung’s functional units composed of two major epithelial cell types, type I and type II. Type II cells are adult lung stem cells, but this study shows that differentiated Type I cells can also self-renew and give rise to Type II cells, revealing a bidirectional relationship between lung epithelial cell types.

Beschreibung: Article lt has been debated for decades if there is a genetic aetiology underlying Möbius syndrome, a neurological disorder characterized by facial paralysis. Here Tomas-Roca et al . use exome sequencing and identify de novo mutations in PLXND1 and REV3L , representing converging pathways in hindbrain development.

Beschreibung: Article Semaphorin ligands and cognate receptors are important in patterning the vasculature. Here, Aghajanian et al. report an unexpected role for ErbB2 in endothelial cells where it partners with Nrp1 to form a novel semaphoring holoreceptor required for embryonic vascular patterning.

Beschreibung: Article It is unclear how often genetic mosaicism of chromosome X arises. Here, the authors examine women with cancer and cancer-free controls and show that X chromosome mosaicism occurs more frequently than on autosomes, especially on the inactive X chromosome, but is not linked to non-haematologic cancer risk Nature Communications doi: 10.1038/ncomms11843 Authors: Mitchell J.

Beschreibung: The Sigma-1 receptor (S1R) is known to play a protective role in the central nervous system including the retina. A major barrier for understanding the underlying mechanism is an ambiguity of S1R subcellular localizations. We thus conducted the first electron microscopy (EM) study of S1R subcellular distribution in the mouse retina. Immuno-EM imaging showed previously under-appreciated S1R presence in photoreceptor cells. Unlike in other cell types in previous reports, in photoreceptor cells S1R was found in the nuclear envelope but not localized in the endoplasmic reticulum (ER), raising a possibility of S1R-mediated modulatory mechanisms different than conventionally thought. While in bipolar cells S1R was detected only in the nuclear envelope, in ganglion cells S1R was identified predominantly in the nuclear envelope and found in the ER as well. A predominant localization of S1R in the nuclear envelope in all three retinal neurons implicates a potential role of S1R in modulating nuclear activities. Moreover, its absence in the plasma membrane and presence in the subsurface ER cisternae that are juxtaposed to the plasma membrane in ganglion cells may lend mechanistic insights generally important for frequently reported S1R modulations of ion channels in neurons.

Beschreibung: Article Bile acids are important for the absorption of nutrients. Here the authors provide a molecular explanation for the oscillatory release of bile acids, showing that diurnal expression of the transcription factor KLF15 regulates FGF15 secretion from enterocytes, which then inhibits bile acid synthesis in the liver.
