Microglia regulate blood clearance in subarachnoid hemorrhage by heme oxygenase-1.

Journal of Clinical Investigation, 2015
Subarachnoid hemorrhage (SAH) carries a 50% mortality rate. The extravasated erythrocytes that surround the brain contain heme, which, when released from damaged red blood cells, functions as a potent danger molecule that induces sterile tissue injury ...

Protein‐Like Polymers Targeting Keap1/Nrf2 as Therapeutics for Myocardial Infarction

Advanced Materials, EarlyView.
We describe a Keap1 targeting protein‐like polymer (PLP) which activates Nrf2, an important cytoprotective transcription factor for relieving myocardial infarction‐induced oxidative stress. This PLP increases cell survival in vitro in multiple relevant cardiac cell types and elicits pro‐reparative responses, improving cardiac function in a preclinical ...

Immunohistochemical Expression of COX2 in Urothelial Carcinoma of the urinary bladder

Advanced Medical Journal
Background and objectives: Urothelial carcinoma of urinary bladder constitutes 90% of bladder cancer cases. Cyclo-oxygenase 2 as an immune-histochemical marker, is not expressed in normal tissues, while it is expressed in some cancers including ...

Impairment of neutrophil oxidative burst in children with sickle cell disease is associated with heme oxygenase-1

Haematologica, 2015
Sickle cell disease is a risk factor for invasive bacterial infections, and splenic dysfunction is believed to be the main underlying cause. We have previously shown that the liberation of heme in acute hemolysis can induce heme oxygenase-1 during ...

RoxB Is a Novel Type of Rubber Oxygenase That Combines Properties of Rubber Oxygenase RoxA and Latex Clearing Protein (Lcp)

Applied and Environmental Microbiology, 2017
Only two types of rubber oxygenases, rubber oxygenase (RoxA) and latex clearing protein (Lcp), have been described so far. RoxA proteins (RoxAs) are c-type cytochromes of ≈70 kDa produced by Gram-negative rubber-degrading bacteria, and they cleave ...

Macrophage HM13/SPP Enhances Foamy Macrophage Formation and Atherogenesis

Advanced Science, EarlyView.
Previous research suggests that AIP may prevent atherogenic foamy macrophage formation. This study reveals that AIP, via its chaperone interaction with AHR, inhibits p38‐c‐JUN‐mediated transactivation of HM13, which encodes the ERAD protease HM13/SPP. HM13/SPP promotes foamy macrophage formation in addition to atherogenesis and plaque foamy macrophage ...

Mechanisms of cell protection by heme oxygenase-1.

Annual Review of Pharmacology and Toxicology, 2010
Heme oxygenases (HO) catabolize free heme, that is, iron (Fe) protoporphyrin (IX), into equimolar amounts of Fe(2+), carbon monoxide (CO), and biliverdin. The stress-responsive HO-1 isoenzyme affords protection against programmed cell death.

CO‐Releasing Polyoxometalates Nanozyme with Gut Mucosal Immunity and Microbiota Homeostasis Remodeling Effects for Restoring Intestinal Barrier Integrity

Advanced Science, EarlyView.
A CO‐releasing polyoxometalates nanozyme (PMC) is engineered by coordinating pentacarbonyl manganese bromide with molybdenum‐based polyoxometalates nanoclusters. PMC exhibits targeted accumulation at IBD sites, efficient ROS scavenging, and responsive CO release.

The protective effects of rutin on the liver, kidneys, and heart by counteracting organ toxicity caused by synthetic and natural compounds

Food Science &Nutrition, Volume 11, Issue 1, Page 39-56, January 2023., 2023
Rutin is a flavonoid present in many plant species. Because of its antioxidant, anti‐inflammatory, and anti‐apoptotic properties, rutin is of interest for its potential protective effects against toxic agents. Rutin has potential therapeutic effectiveness against several toxicants, and its beneficial effects are more than likely mediated by its ...

Patchouli Ethanol Extract Pogostemon cablin Benth. Against Aging Profiles in Doxorubicin‐Induced 3T3‐L1 Fibroblast Cell Lines

AGING MEDICINE, EarlyView.
Pogostemon cablin Benth. (PCEE) is a promising antiaging agent that inhibits ROS, decreases the senescence‐associated β‐galactosidase (SA‐β‐gal) gene, and maintains telomere length in doxorubicin‐induced 3T3‐L1 fibroblast cells. The researchers extend their gratitude to www.freepik.com for providing Figure telomer.
