Biophysical characterization and ion transport with cell‐based and proteoliposome reconstitution assays of invertebrate K+‐Cl− cotransporters

open access: yesFEBS Open Bio, EarlyView.
The K+‐Cl− cotransporters (KCCs) facilitate the symport of ions across the plasma membrane. They participate in physiological processes including neuronal regulation. Here, we characterized KCCs from Drosophila and Hydra vulgaris. Comparative analyses of transporters provide insights into the mechanism of KCC ion transport, regulation, and evolution ...

Regional and local patterns of genetic variation and structure in yellow‐necked mice ‐ the roles of geographic distance, population abundance, and winter severity

open access: yesEcology and Evolution, 2018
The goal of this study, conducted in seven large woodlands and three areas with small woodlots in northeastern Poland in 2004–2008, was to infer genetic structure in yellow‐necked mouse Apodemus flavicollis population and to evaluate the roles of ...

The intrinsic factors in the act of progression in the mammal

open access: yes, 1911
Whilst the act of progression is being performed, the several limbs exhibit rhythmic movements of flexion and of extension. When any limb is in contact with the ground, it extends, and thus serves to propel the animal forwards. At the end of this act the

Heterochromosomes in mammals [PDF]

open access: yesExperimental Biology and Medicine, 1912
Heterochromosomes have now been reported for the male germ cells of the following mammals: man and rat (Guyer, '10); armadillo (Newman and Patterson, '10); opossum (Jordan, '11); guinea-pig (Stevens, '11); and bat (Jordan, '12). Winiwarter and Sainmont, '09, report a longitudinally split “monosome” in the oocyte of the cat.A comparative study of ...

Co‐overexpression of the caloric restriction‐induced mitochondrial factors PGC‐1α and MIPEP upregulates Phospho1 expression in adipocytes

open access: yesFEBS Open Bio, EarlyView.
Caloric restriction that extends lifespan induces the expression of PGC‐1α and MIPEP in white adipose tissue. In this study, co‐overexpression of Pgc‐1α and Mipep upregulated the gene expression of PHOSPHO1. These findings provide new insights into mitochondria‐related mechanisms underlying the effects of caloric restriction in adipocytes.

Characterization of ribosome heterogeneity during endothelial to hematopoietic transition

open access: yesFEBS Open Bio, EarlyView.
The panorama of ribosome heterogeneity during embryonic hematopoiesis has not yet been portrayed. In this study, utilizing dual‐omics data, the heterogenous dynamic of ribosome during endothelial‐to‐hematopoietic transition has been systemically described. Moreover, stage‐specific upregulation and peripheral localization of RPL27 and RACK1 in hemogenic

The E3 ubiquitin ligase, RNF219, suppresses CNOT6L expression to exhibit antiproliferative activity

open access: yesFEBS Open Bio, EarlyView.
We identified RNF219 as a CCR4‐NOT complex‐interacting E3 ubiquitin ligase that targets the CCR4‐NOT subunit CNOT6L for ubiquitination. RNF219 directly binds to the DUF3819 domain of CNOT1 through its putative α‐helix spanning amino acids 521–542. Our findings also suggest that antiproliferative activity of RNF219 is at least partially mediated by ...
