Substratum stiffness tunes membrane voltage in mammary epithelial cells.

J Cell Sci 2021 07 12;134(13). Epub 2021 Jul 12.

Department of Molecular Biology, Princeton University, Princeton, NJ 08544, USA.

Membrane voltage (Vm) plays a critical role in the regulation of several cellular behaviors, including proliferation, apoptosis and phenotypic plasticity. Many of these behaviors are affected by the stiffness of the underlying extracellular matrix, but the connections between Vm and the mechanical properties of the microenvironment are unclear. Here, we investigated the relationship between matrix stiffness and Vm by culturing mammary epithelial cells on synthetic substrata, the stiffnesses of which mimicked those of the normal mammary gland and breast tumors.

Feminising Wolbachia disrupt Armadillidium vulgare Insulin-like signalling pathway.

Cell Microbiol 2021 Jul 27:e13381. Epub 2021 Jul 27.

Université de Poitiers, UMR CNRS 7267 Écologie et Biologie des Interactions, Poitiers, France.

The endosymbiont Wolbachia feminizes male isopods by making them refractory to the insulin-like masculinising hormone, which shunts the autocrine development of the androgenic glands. It was therefore proposed that Wolbachia silences the IR receptors, either by preventing their expression or by inactivating them. We describe here the two IR paralogs of Armadillidium vulgare.

[Clinical and molecular genetic features of 3 family cases of the central precocious puberty, due to gene defects].

Probl Endokrinol (Mosk) 2021 May 11;67(3):55-61. Epub 2021 May 11.

Endocrinology Research Centre; Research Centre for Medical Genetics.

Gonadotropin-dependent precocious puberty (central) is a condition resulting from the early (up to 8 years in girls and 9 years in boys) reactivation of the hypothalamic-pituitary-gonadal axis. An increase in the secretion of sex steroids by the gonads in this form is a consequence of the stimulation of the sex glands by gonadotropic hormones of the pituitary gland. In the absence of central nervous system abnormalities, CPP is classified as idiopathic and as familial in some cases, emphasizing the genetic origin of this disorder. Read More

Expression of the ACE2 Virus Entry Protein in the Nervus Terminalis Reveals the Potential for an Alternative Route to Brain Infection in COVID-19.

Front Cell Neurosci 2021 5;15:674123. Epub 2021 Jul 5.

L. Rydygier Collegium Medicum, Nicolaus Copernicus University, Bydgoszcz, Poland.

Previous studies suggested that the SARS-CoV-2 virus may gain access to the brain by using a route along the olfactory nerve. However, there is a general consensus that the obligatory virus entry receptor, angiotensin converting enzyme 2 (ACE2), is not expressed in olfactory receptor neurons, and the timing of arrival of the virus in brain targets is inconsistent with a neuronal transfer along olfactory projections. We determined whether nervus terminalis neurons and their peripheral and central projections should be considered as a potential alternative route from the nose to the brain. Read More
