MPO, myeloperoxidase (MPO): Click to Expand ⟱
Source:
Type:
Myeloperoxidase (MPO) is a heme-containing peroxidase most commonly associated with neutrophils and certain other myeloid cells. It plays a critical role in the innate immune response by generating reactive oxygen species (ROS) during the respiratory burst, which can destroy pathogens.

MPO is predominantly expressed in neutrophils and monocytes, where it catalyzes the formation of hypochlorous acid (HOCl) and other ROS from hydrogen peroxide and chloride ions.
The generation of ROS by MPO is essential for antimicrobial defense; however, these reactive molecules can also induce oxidative stress in the tumor microenvironment.

MPO is not typically expressed by tumor cells themselves, but high levels can be found in tumor-infiltrating immune cells (e.g., neutrophils) or in areas of chronic inflammation.

2508- H2,    Molecular hydrogen is a promising therapeutic agent for pulmonary disease
- Review, Var, NA - Review, Sepsis, NA
*ROS↓, inhalation of 2% molecular hydrogen results in the selective scavenging of hydroxyl free radical (·OH) and peroxynitrite anion (ONOO-), significantly improving oxidative stress injury caused by cerebral ischemia/reperfusion (I/R)
eff↝, Molecular hydrogen can exert biological effects on almost all organs, including the brain, heart, lung, liver, and pancreas.
*Inflam↓, including roles in the regulation of oxidative stress and anti-inflammatory and anti-apoptotic effects
*NRF2↑, By stimulating nuclear factor erythroid 2-related factor 2 (Nrf2), which regulates the basal and induces expression of many antioxidant enzymes
*HO-1↑, hydrogen can increase the expression of heme oxygenase-1 (HO-1)
*SOD↑, increases the activity of the antioxidant enzymes SOD, CAT, and myeloperoxidase (MPO)
*Catalase↑,
*MPO↑,
*ASK1↓, Molecular hydrogen can block the apoptosis signal-regulating kinase 1 (ASK1) signaling pathway
*NADPH↓, thereby inhibiting nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity and decreasing free radical production
*Sepsis↓, Emerging evidence suggests that hydrogen can prevent sepsis, providing a novel treatment strategy for sepsis-induced ALI.
*HMGB1↓, Hydrogen attenuates tissue injury and dysfunction by inhibiting HMGB-1.
ROS↑, it has been shown that hydrogen pretreatment enhances ROS and the expression of pyroptosis-related proteins, stimulates NLRP3 inflammasome/gasdermin D (GSDMD) activation, and inhibits endometrial cancer
NLRP3↑,
GSDMD↑,
chemoP↑, Hydrogen can alleviate the side effects of conventional anti-cancer therapies, such as chemotherapy and radiotherapy, and improve quality of life
eff↑, It significantly improves the physical status of patients, reduces fatigue, insomnia, anorexia, and pain, and decreases elevated tumor markers.

2100- TQ,    Dual properties of Nigella Sative: Anti-oxidant and Pro-oxidant
- Review, NA, NA
ROS⇅, Pubmed data indicated that NS has both anti-oxidant and pro-oxidant properties in different cell types
*antiOx↑, NS acts as an anti-oxidant by scavenging ROS [4]. It can ameliorate ischemic reperfusion injury conditions and attenuated ROS in heart [5] intestine [6] and kidney [7]
*SOD↑, improved the activities of various enzymes like superoxide dismutase [SOD] and myeloperoxidase (MPO)
*MPO↑,
*neuroP↑, NS oil has been found to be neuroprotective against oxidative stress in epileptogenesis, pilocarpine-induced seizures [25] and opioid tolerance
*chemoP↑, Anticancer drugs leave toxic effect due to over-production of ROS. NS oil or TQ can potentially up-regulate anti-oxidant mechanisms caused by anticancer drug
*radioP↑, NS seed extracts can protect normal tissue from oxidative damage during radiotherapy of cancer patients [35,36]
NF-kB↓, TQ has been shown to exhibit down regulation of NF-κB expression in lung cancer cells
IAP1↓, Anti-apoptotic (IAP1, IAP2, XIAP Bcl-2, Bcl-xL, survivin), proliferative (cyclin D1, cyclooxygenase-2, and c-Myc) and angiogenic genes (matrix metalloproteinase-9 orMMP-9) and vascular endothelial growth factor (VEGF) were down-regulated
IAP2↓,
XIAP↓,
Bcl-xL↓,
survivin↓,
COX2↓,
MMP9↓,
VEGF↓,
ROS↑, TQ causes release of ROS in ABC cells which in turn inhibits NF-κB activity
P21↑, TQ up regulated the expression of p21 and down regulated the histone deacetylase (HDAC) activity and induced histone hyperacetylation causing induction of apoptosis and inhibition of proliferation in pancreatic cancer cell
HDAC↓,
GSH↓, TQ was found to decrease glutathione (GSH) levels in prostate cancer cells resulting in up-regulated expression of GADD45 alpha (growth arrest and DNA damage inducible gene) and AIF
GADD45A↑,
AIF↑,
STAT3↓, TQ suppressed the STAT 3; the signal transducer and activator of transcription which is involved in the abnormal transformation of a number of human malignancies [53].
