Strontium Ranelate Elevates Expression of Heme Oxygenase-1 and Decreases Alveolar Bone Loss in Rats

eJournal of Oral Maxillofacial Research, 2018
Objectives: The purpose of this study was to determine the effects of strontium ranelate on ligature-induced periodontitis in rats and assess the putative involvement of heme oxygenase-1 (HO-1) pathway in these effects.

The silent information regulator 1 pathway attenuates ROS-induced oxidative stress in Alzheimer's disease [PDF]

Journal of Integrative Neuroscience, 2020
We show that down-regulation of circular ribonucleic acid 0001588 with small interfering-circular ribonucleic acid 0001588 mimics promoted caspase-3 and caspase-9 activity levels, increased lactate dehydrogenase activity levels, and reduced cell growth ...

Regulation of haem oxygenase-1 nitrosative stress in cardiac cells. [PDF]

, 2005
The reactive nitrogen species (RNS) nitric oxide (NO), nitroxyl anion (NO") and nitrosonium cation (NO+), modulate a myriad of biological processes. The microsomal haem oxygenases (HO-1, HO-2 and HO-3) oxidatively catabolise haem to bilirubin, carbon ...

Gm26550 Modulates Learning and Memory by Increasing IGF1 mRNA Expression and Stability in Nrf2−/− Mice

Advanced Science, EarlyView.
The present study shows that Nrf2 directly binds to the Gm26550 promoter, thereby activating Gm26550 transcription and increasing its expression. Mechanistically, Gm26550 promotes IGF1 expression by functionally antagonizing miR‐26a‐5p‐mediated repression and sequestering the RBP KHSRP, thereby enhancing hippocampal neuronal synaptic plasticity and ...

Role of sphingosine-1-phosphate receptor 1 and downstream heme oxygenase-1 induction in alternative macrophage activation induced by apoptotic cells [PDF]

, 2010
Macrophages show a remarkable functional plasticity, which enables them to change their phenotype in response to environmental signals. They are key players during infection by initiating inflammation through the release of proinflammatory mediators ...

SIRT5‐Mediated Desuccinylation of ACAA2 Protects Against Calcium Oxalate‐Induced Kidney Injury by Regulating Fatty Acid Oxidation to Suppress Mitochondrial Oxidative Injury and Ferroptosis

Advanced Science, EarlyView.
The SIRT5/ACAA2 axis maintains lipid metabolic homeostasis in RTECs by promoting ACAA2 desuccinylation and preserving its stability and enzymatic activity, thereby sustaining FAO and limiting PUFA and PUFA‐containing phospholipid accumulation. Under CaOx stress, SIRT5 downregulation impairs FAO, promotes oxidative stress and ferroptosis, and enhances ...

Fibroblast growth factor 21 inhibits ferroptosis following spinal cord injury by regulating heme oxygenase-1

Neural Regeneration Research
Interfering with the ferroptosis pathway is a new strategy for the treatment of spinal cord injury. Fibroblast growth factor 21 can inhibit ferroptosis and promote neurofunctional recovery, while heme oxygenase-1 is a regulator of iron and reactive ...

Cytoprotective role of heme oxygenase-1 upregulation in progressive renal disease [PDF]

Einstein (São Paulo), 2009
Objective: This study evaluated the ability of heme oxygenase-1 to prevent or reverse renal fibrosis. Methods: Sprague-dawley male rats were submitted to unilateral ureteral obstruction and divided into groups: non-treated and hemin.

A ROS‐Responsive and Mucoadhesive Thermosensitive Hydrogel Encapsulated with Mizoribine for Synergistic Dry Eye Therapy

Advanced Science, EarlyView.
The ROS‐responsive in situ thermosensitive MZR@SPPP hydrogel system enables dual‐stage drug loading and sustained ocular delivery. Upon administration, it gelates at ocular surface temperature, enhancing ocular adhesion. By scavenging free radicals, restoring NRF2‐mediated antioxidant defense and mitochondrial homeostasis, and suppressing inflammatory ...
