Light-induced depigmentation in planarians models the pathophysiology of acute porphyrias

open access: yeseLife, 2016
Porphyrias are disorders of heme metabolism frequently characterized by extreme photosensitivity. This symptom results from accumulation of porphyrins, tetrapyrrole intermediates in heme biosynthesis that generate reactive oxygen species when exposed to ...

Heme oxygenase-1 accelerates erastin-induced ferroptotic cell death

open access: yesOncoTarget, 2015
The oncogenic RAS-selective lethal small molecule Erastin triggers a unique iron-dependent form of nonapoptotic cell death termed ferroptosis. Ferroptosis is dependent upon the production of intracellular iron-dependent reactive oxygen species (ROS), but

Bioinspired Tissue Transparency: Achieving Sclera‐to‐Cornea Transplantation

open access: yesAdvanced Science, EarlyView.
A bioinspired decellularization‐compression‐locking tactic (DCLT) is developed to transform human sclerae into transparent corneal substitutes. These clear, robust, and pro‐regenerative substitutes are capable of repairing complex corneal injuries, including chemical burns, keratoconus, and penetrating wounds, demonstrating their clinical potential to ...

Quantification of labile heme in live malaria parasites using a genetically encoded biosensor

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2017
Significance Malaria parasites degrade substantial quantities of hemoglobin to release heme within a specialized digestive vacuole. Most of this heme is sequestered in an inert crystal.

Esketamine/Ketamine: Dual‐Action Mechanisms and Clinical Prospects beyond Anesthesia in Psychiatry, Immunology, and Oncology

open access: yesAdvanced Science, EarlyView.
Esketamine and ketamine are widely used for perioperative analgesia and anesthesia. Despite their established roles in analgesia, sedation, and anesthesia, as well as emerging antidepressant, anti‐tumor, and anti‐inflammatory effects, their clinical use is limited due to side effects and addiction potential.

Characterization of plasma labile heme in hemolytic conditions

open access: yesThe FEBS Journal, 2017
Extracellular hemoglobin, a byproduct of hemolysis, can release its prosthetic heme groups upon oxidation. This produces metabolically active heme that is exchangeable between acceptor proteins, macromolecules and low molecular weight ligands, termed ...

Mechanisms of Direct Electron Transfer Governed by Redox‐Active Conductive Carrier with Superior Wettability in Anaerobic Biofilms

open access: yesAdvanced Science, EarlyView.
A redox‐active conductive carrier of tannic acid‐modified iron‐biochar with superior wettability is demonstrated to regulate direct electron transfer at the anaerobic biofilm‐carrier interface by enhancing the cytochrome c‐mediated pathway. For the first time, integrated evidence from spectroscopy, electrochemical analyses, and metatranscriptomics ...

Heme dynamics and trafficking factors revealed by genetically encoded fluorescent heme sensors

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2016
Significance All heme-dependent functions require the mobilization of labile heme (LH), of which there is little understanding of its nature and dynamics.
