Molecular Dynamics Simulations Based on Newly Developed Force Field Parameters for Cu2+ Spin Labels Provide Insights into Double-Histidine-Based Double Electron–Electron Resonance [PDF]

open access: yes, 2020
Electron paramagnetic resonance (EPR) in combination with the recently developed double-histidine (dHis)-based Cu2+ spin labeling has provided valuable insights into protein structure and conformational dynamics.

A yeast model of 5‐oxoproline accumulation reveals a general toleration to 5‐oxoproline

open access: yesFEBS Open Bio, EarlyView.
Using a yeast model, we show that even high accumulation of 5‐oxoproline causes only mild cellular stress and does not trigger oxidative stress. Instead, cells adapt by activating efflux pumps and diverse protective pathways, suggesting that previously proposed harmful effects of 5‐oxoproline may arise from indirect metabolic imbalances rather than the

Effects of reduced metabolizable protein diets supplemented with rumen-protected His under adequate Met and Lys supply on production, nutrient digestibility, N utilization, and manure ammonia emissions in lactating cows

open access: yesJournal of Dairy Science
: Balancing for limiting AA may prevent reduced production when deficient MP is provided. The objective of the study was to determine the effects of rumen-protected (RP) His supplementation at different levels of MP when Lys and Met supplies meet the ...

Histidine-Rich Cell-Penetrating Peptide for Cancer Drug Delivery and Its Uptake Mechanism [PDF]

open access: yes, 2019
In this work, we report a drug delivery system based on the pH-responsive self-assembly and -disassembly behaviors of peptides. Here, a systematically designed histidine-rich lipidated peptide (NP1) is presented to encapsulate and deliver an anticancer ...

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

open access: yesFEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Global regulation and virulence mediated by the histidine-responsive local transcription factor HutC in Pseudomonas aeruginosa

open access: yesmBio
Host-derived nutritional substrates fuel infection in invading bacteria, yet their potential as signaling molecules for host perception remains largely unexplored.

Histidine limitation alters plant development and influences the TOR network [PDF]

open access: yes
Plant growth depends on growth regulators, nutrient availability, and amino acid levels, all of which influence cell wall formation and cell expansion. Cell wall integrity and structures are surveyed and modified by a complex array of cell wall integrity

Coordinative peptide recognition. Making intermolecular processes intramolecular [PDF]

open access: yes, 2006
The design of synthetic receptors that function under physiological conditions is still a challenge. A successful strategy is the use of reversible coordination of Lewis-basic guest molecules to Lewis-acidic metal complexes to provide high and selective ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Small RNA pathways in mammalian oocytes

open access: yesFEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...
