CD177 Deficiency Defines a Stable Subtype of Human Neutrophil Granulocytes with Tumor Promoting Activity

open access: yesAdvanced Science, EarlyView.
Human neutrophils exist as two epigenetically imprinted subtypes defined by stable CD177 expression or absence — a ratio that persists across time, circadian rhythms, and inflammation. CD177− neutrophils display a distinct molecular landscape enriched in arginase 1 and lipid metabolism markers, accumulate in head‐and‐neck tumors, and associate with ...

Loss of Frataxin induces iron toxicity, sphingolipid synthesis, and Pdk1/Mef2 activation, leading to neurodegeneration

open access: yeseLife, 2016
Mutations in Frataxin (FXN) cause Friedreich’s ataxia (FRDA), a recessive neurodegenerative disorder. Previous studies have proposed that loss of FXN causes mitochondrial dysfunction, which triggers elevated reactive oxygen species (ROS) and leads to the

Nano‐Backpack Engineered Probiotics with Reactive Oxygen Species–Responsive Tungsten Release for Synergistic Therapy of Inflammatory Bowel Disease

open access: yesAdvanced Science, EarlyView.
An integrated probiotic system is engineered to execute a programmed therapeutic cascade against inflammatory bowel disease. Upon pathological signals, the system sequentially performs ROS scavenging, tungsten release, and selective pathogen suppression, thereby breaking the oxidative stress–dysbiosis cycle to remodel gut microbiota and reinforce ...

Sphingolipid Signaling in Metabolic Disorders

open access: yes, 2012
Sphingolipids, ubiquitous membrane lipids in eukaryotes, carry out a myriad of critical cellular functions. The past two decades have seen significant advances in sphingolipid research, and in 2010 a first sphingolipid receptor modulator was employed as ...

Orm family proteins mediate sphingolipid homeostasis [PDF]

open access: yes, 2010
Despite the essential roles of sphingolipids both as structural components of membranes and critical signalling molecules, we have a limited understanding of how cells sense and regulate their levels.

Mechanistic investigation of Liujing Toutong tablet in the treatment of cerebral ischemia–reperfusion injury in rats by the integration of serum pharmacochemistry and metabolomics

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The research strategy for pharmacodynamics, serum pharmacochemistry, metabolomics, and network pharmacology analysis method in intervention effects of LTT are illustrated. Abstract Background Liujing Toutong tablet (LTT) is a traditional Chinese patent medicine.

UHPLC–MS based metabolomics study of the ErZhi formula on skeletal muscle against osteosarcopenia focusing on energy metabolism

open access: yesAnimal Models and Experimental Medicine, EarlyView.
ErZhi formula (EZF) is composed of Ligustri Lucidi Fructus (LLF) and Ecliptae herba (EH). Ovariectomized (OVX) and sham rats received 12‐week intragastric treatment with EZF, alendronate, and vehicle saline. Gastrocnemius tissues were harvested to systematically evaluate pharmacodynamic changes in skeletal muscle morphology, mitochondrial ...

Use of isotopically labeled substrates reveals kinetic differences between human and bacterial serine palmitoyltransferase

open access: yesJournal of Lipid Research, 2019
Isotope labels are frequently used tools to track metabolites through complex biochemical pathways and to discern the mechanisms of enzyme-catalyzed reactions.

Comparison of Receptor‐Mediated Endocytosis and Its Application to Enhance DNA Transfection by TFAMoplex

open access: yesAdvanced NanoBiomed Research, EarlyView.
We developed an assay to distinguish cellular binding from internalization. Compatible with microscopy and high‐throughput screening, the method identifies ligand‐mediated uptake. Applying top candidates to a protein‐based DNA carrier enhanced transfection efficiency, providing a rational strategy to improve non‐viral gene delivery systems.
