Pathogen‐Centric Activation of an Azoreductase‐Responsive Antibody‐Antibiotic Conjugate for the Targeted Eradication of MRSA

open access: yesAdvanced Science, EarlyView.
A pathogen‐centric antibody‐antibiotic conjugate (AZO‐AAC) releases antibiotics via bacterial azoreductase, independent of host‐lysosomal function. This mechanism achieves nanomolar eradication of both planktonic and intracellular methicillin‐resistant Staphylococcus aureus (MRSA).

PIEZO1 is Required for Acute Myeloid Leukemia Progression and Leukemia Stem Cell Maintenance via HIF1A‐SLC7A11 Axis‐Mediated Ferroptosis Defense

open access: yesAdvanced Science, EarlyView.
This study identifies the mechanosensor PIEZO1 as a key factor in promoting acute myeloid leukemia progression and uncovers a ferroptosis defense system mediated by PIEZO1‐HIF1A‐SLC7A11 axis that is essential for leukemia stem cell maintenance. This ferroptotic defense system may represent a unique vulnerability for leukemia stem cells, providing a ...

Glutathione Reductase Deficiency in Saudi Arabia

open access: yesAnnals of Saudi Medicine, 1989
Glutathione reductase [GR]is a ubiquitous enzyme required for the conversion of oxidized glutathione [GSSG] to reduced glutathione [GSH] concomitantly oxidizing reduced nicotinamide adenine dinucleotide phosphate [NADPH]in a reaction essential for the stability and integrity of red cells.

Natural History of Chronic Kidney Disease in Sickle Cell Disease

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Kidney complications, referred to as nephropathy, develop early in sickle cell disease (SCD). In addition to its known morbidity, abundant data show that chronic kidney disease (CKD) is associated with an increased mortality risk in SCD. Increasing evidence suggests that the natural history of SCD nephropathy is progressive. Initial glomerular

Exogenous sucrose influences antioxidant enzyme activities and reduces lipid peroxidation in water-stressed cucumber leaves

open access: yesBiologia Plantarum, 2015
To investigate whether exogenous sucrose can protect cucumber from water stress, cucumber (Cucumis sativus L.) seedlings were pretreated with 90 mM sucrose or 90 mM mannitol for 1 d and then were dehydrated with 10 % (m/v) polyethylene glycol (PEG) 6000 ...

Rat liver antioxidant response to iron and copper overloads [PDF]

open access: yes, 2014
The rat liver antioxidant response to Fe and Cu overloads (0–60 mg/kg) was studied. Dose- and time-responses were determined and summarized by t1/2 and C50, the time and the liver metal content for half maximal oxidative responses.

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

open access: yesAdvanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

Activation of 3-Mercaptopyruvate Sulfurtransferase by Glutaredoxin Reducing System

open access: yesBiomolecules, 2020
Glutaredoxin (EC 1.15–1.21) is known as an oxidoreductase that protects cysteine residues within proteins against oxidative stress. Glutaredoxin catalyzes an electron transfer reaction that donates an electron to substrate proteins in the reducing system
