Functional role of the Frizzled linker domain in the Wnt signaling pathway

open access: yesCommunications Biology, 2022
The linker domain of Frizzled receptors has a varying effect on the functional levels of canonical and non-canonical Wnt signaling, with FZD chimeras influencing the binding of Wnt proteins and the recruitment of proteins regulating downstream signaling.

2D hybrid analysis: Approach for building three-dimensional atomic model by electron microscopy image matching

open access: yesScientific Reports, 2017
In this study, we develop an approach termed “2D hybrid analysis” for building atomic models by image matching from electron microscopy (EM) images of biological molecules.

Active and water-soluble form of lipidated Wnt protein is maintained by a serum glycoprotein afamin/α-albumin

open access: yeseLife, 2016
Wnt plays important role during development and in various diseases. Because Wnts are lipidated and highly hydrophobic, they can only be purified in the presence of detergents, limiting their use in various in vitro and in vivo assays.

Sequencing refractory regions in bird genomes are hotspots for accelerated protein evolution

open access: yesBMC Ecology and Evolution, 2021
Background Approximately 1000 protein encoding genes common for vertebrates are still unannotated in avian genomes. Are these genes evolutionary lost or are they not yet found for technical reasons?

In vivo effect of dried chicory root (Cichorium intybus L.) on xenobiotica metabolising cytochrome P450 enzymes in porcine liver [PDF]

open access: yes, 2011
Cytochrome P450 (CYP) enzymes are widely studied for their involvement in metabolism of drugs and endogenous compounds. In porcine liver, CYP1A2,2Aand 2E1 are important for the metabolism of skatole.Feeding chicory roots to pigs is known to decrease the ...

Tissue environment, not ontogeny, defines murine intestinal intraepithelial T lymphocytes

open access: yeseLife, 2021
Tissue-resident intestinal intraepithelial T lymphocytes (T-IEL) patrol the gut and have important roles in regulating intestinal homeostasis. T-IEL include both induced T-IEL, derived from systemic antigen-experienced lymphocytes, and natural T-IEL ...

Quality control of protein reagents for the improvement of research data reproducibility

open access: yesNature Communications, 2021
Proteins and peptides are amongst the most widely used research reagents but often their quality is inadequate and can result in poor data reproducibility. Here we propose a simple set of guidelines that, when correctly applied to protein reagents should

Tadalafil modulates aromatase activity and androgen receptor expression in a human osteoblastic cell in vitro model [PDF]

open access: yes, 2016
Purpose Phosphodiesterase type-5 inhibitor (PDE5i) tadalafil administration in men with erectile dysfunction is associated with increased testosterone/estradiol ratio, leading to hypothesize a potential increased effect of androgen action on target ...
