Interpreting the effects of DNA polymerase variants at the structural level

open access: yesMolecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Effects of Ca2+ on the Cross-linking of Sea Cucumber Collagen Fibers during Thermal Processing

open access: yesShipin gongye ke-ji
During the thermal processing of sea cucumbers, changes in the CFs structure affect their textural characteristics and can lead to certain nutritional losses.

Kinetics of the thapsigargin-induced Ca2+ mobilisation: A quantitative analysis in the HEK-293 cell line

open access: yesFrontiers in Physiology, 2023
Thapsigargin (TG) inhibits the sarco/endoplasmic reticulum Ca2+ ATPase (SERCA) pump and, when applied acutely, it initiates a Ca2+ mobilisation that begins with the loss of Ca2+ from the endoplasmic reticulum (ER) and culminates with store-operated Ca2 ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

The relaxant responses induced by ethanol in the smooth muscle: role of extracellular and intracellular Ca2+ [Duz kasta etanol ile induklenen gevseme cevaplari: ekstraseluler ve intraseluler Ca2+’un rolu]

open access: yesMedicine Science, 2016
Since worldwide alcohol consumption, the understanding the mechanism of action of ethanol is important in the gastrointestinal tract. In this study we aimed to clarify the role of extracellular and intracellular calcium (Ca2+) on relaxations induced by ...

Identification of functional murine mitochondrial formyl peptides and their effects on myeloid‐derived suppressor cell generation

open access: yesFEBS Open Bio, EarlyView.
We first identified functional murine mitochondrial N‐formyl peptides (MT‐FPs) and investigated their effects on the in vitro myeloid‐derived suppressor cell (MDSC) generation from bone marrow cells. We demonstrated that MT‐FPs acted directly on bone marrow cells to promote MDSC generation and modulated the polymorphonuclear (PMN)‐MDSC/monocyte (M ...

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Control of Ca2+ influx by manipulation of Ca2+ and/or Ca2+ antagonist in cardioplegic arrest.

open access: yesJapanese Circulation Journal, 1993
Maximum deactivation of the contractile elements using Ca2+ minimizes oxygen requirements during global ischemia, Ca2+ antagonists and Ca(2+)-free cardioplegia solutions are methods by which the Ca2+ flux can be manipulated. This study was performed with 5 experimental groups: 1) Standard cardioplegia (with Ca2+), 2) Ca(2+)-free cardioplegia, 3) Ca(2+)-
