Previously we have shown that, unlike wild-type mice (WT), heme oxygenase-1 knockout (HO-1-/-) mice developed nitrate tolerance and were not protected from inflammation caused by ischemia-reperfusion (I/R) when preconditioned with a H2S donor. We hypothesized that stimulation (with BAY 41-2272) or
The effects of cilostazol on stimulating heme oxygenase (HO)-1 expression including signal pathways and suppression of inflammatory cytokines and molecules were studied. Cilostazol stimulation time (1-8 h)- and concentration (1-30 μM)-dependently increased the HO-1 mRNA and protein expression
In previous studies, we have shown that heme oxygenase (HO)-2 null [HO-2(-/-)] mice exhibit a faulty response to injury; chronic inflammation and massive neovascularization replaced resolution of inflammation and tissue repair. Endothelial cells play an active and essential role in the control of
1. It is well-established that inhibitors of cyclo-oxygenase (COX) and hence of prostaglandin (PG) biosynthesis reverse inflammatory hyperalgesia and oedema in both human and animal models of inflammatory pain. 2. Paw oedema and hyperalgesia in rats were induced by injecting carrageenan (250 micro g
Dalbergia odorifera T. Chen (Leguminosae) grows in Central and South America, Africa, Madagascar, and Southern Asia. D. odorifera possesses many useful pharmacological properties, such as antioxidative and anti-inflammatory activities in various cell types. 4-Methoxydalbergione (MTD) and
Epidemiological findings support the hypothesis that type 2 diabetes mellitus (T2DM) is a risk factor for osteoarthritis (OA). Moreover, OA cartilage from patients with T2DM exhibits a greater response to inflammatory stress, but the molecular mechanism is unclear. To investigate whether the
OBJECTIVE
Interleukin-6 (IL-6) is a key proinflammatory cytokine that has been considered to be important in the pathogenesis of periodontal disease. Therefore, host-modulatory agents directed at inhibiting IL-6 appear to be beneficial in terms of attenuating periodontal disease progression and
Heme oxygenase (HO) is well known as the rate-limiting enzyme in the oxidative degradation of heme to biliverdin, carbon monoxide (CO), and iron. Based on recent evidence that overexpression of HO-1 confers protection against various types of cell and tissue injury by regulating apoptotic cell death
Gut mucosal injury observed during ischemia-reperfusion is believed to trigger a systemic inflammatory response leading to multiple organ failure. It should be interesting to demonstrate this relationship between gut and multiple organ failure in a sepsis model. Intestinal preconditioning (PC) can
Deoxynivalenol (DON) is one of the most common mycotoxins which contaminate cereals and their by-products worldwide. Previous studies have stated toxic effects of DON on liver. Heme oxygenase-1 (HO-1) plays a potential role in protecting liver and maintaining gut microbiota homeostasis. Therefore, a
OBJECTIVE
To investigate the effect of sinomenine on lipopolysaccharide (LPS)-induced inflammation in RAW264.7 macrophages and the underlying mechanisms. Methods: The mouse RAW264.7 macrophages were treated with sinomenine and/or LPS with or without heme oxygenase-1 (HO-1) inhibitor Znpp. Real-time
Intrauterine inflammation affects fetal lung development. BTB and CNC homology 1 (Bach1) is a transcriptional repressor of heme oxygenase-1 (HO-1) and interleukin-6 (IL-6) genes. We investigated the role of Bach1 in the development of fetal mouse lungs exposed to lipopolysaccharide Toll-like receptors (TLRs) are involved in the progression of ischemic brain injury and hence vascular dementia; however, the underlying mechanisms are largely unknown. Here, we have investigated the interrelationship between stress-responsive heme oxygenase (HO)-1 isoenzyme and TLR4 during chronic
Infection during pregnancy can disrupt regulatory/effector immune system balance, resulting in adverse pregnancy and fetal-neonatal outcomes. Heme oxygenase-1 (HO-1) is a major regulatory enzyme in the immune system. We observed maternal immune response dysregulation during late gestational
Monocytes are composed of two distinct subpopulations in the peripheral blood as determined by their surface antigen expressions, profiles of cytokine production and functional roles played in vivo. We attempted to delineate the unique functional roles played by a minor CD16(high)CCR2(-)
