Plasma free fatty acid levels influence Zn2+-dependent histidine-rich glycoprotein-heparin interactions via an allosteric switch on serum albumin [PDF]

open access: yes, 2014
Background: Histidine-rich glycoprotein (HRG) regulates coagulation, through its ability to bind and neutralize heparins. HRG associates with zinc ions (Zn2+) to stimulate HRG-heparin complex formation. Under normal conditions the majority of plasma Zn2+

Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

Lipolytic degradation, water and flavor properties of low sodium dry cured beef

open access: yesInternational Journal of Food Properties, 2019
The high sodium diet is harmful to the human body. In this study, beef was cured with some salt substitutes, namely SS, 39.7% NaCl, 51.3% KCl, 7% L-lysine and 2% L-histidine, in order to reduce the Na content for the final products, and salt substitute ...

Transcription Factor Promiscuity Drives Regulatory Rewiring and Evolvability in Gene Networks in Bacteria

open access: yesAdvanced Science, EarlyView.
When a master transcription factor (TF) is lost, bacteria can rapidly rewire gene regulatory networks by co‐opting related regulators. Using experimental evolution in Pseudomonas fluorescens, we show that TF promiscuity (low‐level, non‐cognate binding) provides the raw material for rewiring. Successful co‐option follows a predictable hierarchy governed

Alleviation of Ischemia-Induced Brain Edema by Activation of the Central Histaminergic System in Rats

open access: yesJournal of Pharmacological Sciences, 2008
We have reported that facilitation of central histaminergic activity prevents the development of ischemia-induced brain injury. Since cerebral edema is a major cause of brain damage, we studied effects on brain edema of postischemic administration of l ...

Low levels of hydrogen peroxide and L-histidine induce DNA double-strand breakage and apoptosis.

open access: yes, 1996
The results presented in this study demonstrate that L-histidine triggers a lethal response in U937 cells exposed to nontoxic, albeit growth-inhibitory, levels of H2O2.

TRAIP Mediates Alcohol‐Induced Liver Injury through Regulating β‐catenin Ubiquitin Degradation via Direct Interaction

open access: yesAdvanced Science, EarlyView.
This study reveals that NF‐κB1‐driven TRAIP upregulation in ALD correlates with disease severity. Mechanistically, TRAIP directly binds β‐catenin via its CC domain and promotes its K48‐linked ubiquitination and degradation, which is independent of the GSK3β/β‐TrCP pathway.

The Adaptive Degradation of L-Histidine by Paracolobactrum aerogenoides [PDF]

open access: yesJournal of General Microbiology, 1960
SUMMARY: The characteristics of an induced enzyme system responsible for the degradation of l-histidine by a soil organism were studied. Induction could be achieved by exposing cells to l-histidine, d-histidine, urocanate, β-alanyl-l-histidine or l-histidyl-l-histidine, but not by exposure to a variety of other imidazoles.

Auto‐Downregulation of the Florigen FT Production Prevents Precocious Flowering in Plants

open access: yesAdvanced Science, EarlyView.
This study shows that the leaf vein‐expressed FD complexes with the florigen FT to bind DNA motifs in FT promoter, which antagonizes CONSTANS‐mediated FT activation to feedback down‐regulate FT expression. This prevents an excessive induction of FT expression by inductive photoperiods, thereby precluding precocious transition to flowering in ...

Biofilm‐Binding Phages Enhance Biofilm Eradication by Synergistic Photothermal and Photodynamic Therapy

open access: yesAdvanced Science, EarlyView.
Engineered phage‐based trifunctional nanofibers are developed for synergistic biofilm eradication. Biofilm‐binding phages, armed with AuNPs and TCPP, serve as both warheads and scaffolds, endowing the phototherapy agents with biofilm‐anchoring ability. Upon light irradiation, AuNPs induce photothermal therapy, while TCPP generates 1O2 for photodynamic ...
