Common and dissociable effects of oxytocin and lorazepam on the neurocircuitry of fear [Neuroscience]
Benzodiazepines (BZDs) represent the gold standard of anxiolytic pharmacotherapy; however, their clinical benefit is limited by side effects and addictive potential. Consequently, there is an urgent need to develop novel and safe anxiolytics. The peptide hormone oxytocin (OXT) exhibits anxiolytic-like properties in animals and humans, but whether OXT and BZDs…

A pervasive magnetic field effect on an aromatic molecule is…

ZBED2 is an antagonist of interferon regulatory factor 1 and modifies cell identity in pancreatic cancer [Cell Biology]
Lineage plasticity is a prominent feature of pancreatic ductal adenocarcinoma (PDA) cells, which can occur via deregulation of lineage-specifying transcription factors.

Spatiotemporal regulation of PEDF signaling by type I collagen remodeling [Biophysics and Computational Biology]
Dynamic remodeling of the extracellular matrix affects many cellular processes, either directly or indirectly, through the regulation of soluble ligands; however, the mechanistic details of this process remain largely unknown.

Dynamics in a simple evolutionary-epidemiological model for the evolution of an initial asymptomatic infection stage [Ecology]
Pathogens exhibit a rich variety of life history strategies, shaped by natural selection. An important pathogen life history characteristic is the propensity to induce an asymptomatic yet productive (transmissive) stage at the beginning of an infection. This characteristic is subject to complex trade-offs, ranging from immunological considerations to population-level social…

RNA-binding motifs of hnRNP K are critical for induction of antibody diversification by activation-induced cytidine deaminase [Immunology and Inflammation]
Activation-induced cytidine deaminase (AID) is the key enzyme for class switch recombination (CSR) and somatic hypermutation (SHM) to generate antibody memory. Previously, heterogeneous nuclear ribonucleoprotein K (hnRNP K) was shown to be required for AID-dependent DNA breaks. Here, we defined the function of major RNA-binding motifs of hnRNP K, GXXGs…

Collateral fitness effects of mutations [Evolution]
The distribution of fitness effects of mutation plays a central role in constraining protein evolution.

Reprogrammability offers further opportunities for tuning structural and material…

Histone H3K9 methylation promotes formation of genome compartments in Caenorhabditis elegans via chromosome compaction and perinuclear anchoring [Cell Biology]
Genomic regions preferentially associate with regions of similar transcriptional activity, partitioning genomes into active and inactive compartments within the nucleus. Here we explore mechanisms controlling genome compartment organization in Caenorhabditis elegans and investigate roles for compartments in regulating gene expression. Distal arms of C. elegans chromosomes, which are enriched for..

Individualized mosaics of microbial strains transfer from the maternal to the infant gut
Researchers have used a microbiome 'fingerprint' method to report that an individualized mosaic of microbial strains is transmitted to the infant gut microbiome from a mother giving birth through vaginal delivery. They detailed this transmission by analyzing existing metagenomic databases of fecal samples from mother-infant pairs, as well as analyzing mouse dam and pup transmission in a germ-free,

Seahorse and pipefish study opens window to marine genetic diversity
The direction of ocean currents can determine the direction of gene flow in rafting species, but this depends on species traits that allow for rafting propensity. This is according to a study focusing on seahorse and pipefish species. And it could explain how high genetic diversity can contribute to extinction in small populations.

Protein shredder regulates fat metabolism in the brain
A protein shredder that occurs in cell membranes of brain cells apparently also indirectly regulates the fat metabolism. The shredder, known as gamma-secretase, is considered a possible target for drugs against cancer and Alzheimer's disease. However, the results suggest that such agents may have long-range effects that need to be watched closely.
