NOX4, NADPH oxidase 4: Click to Expand ⟱
Source:
Type:
NOX4 (NADPH oxidase 4) is a member of the NADPH oxidase (NOX) family of enzymes, which are responsible for generating reactive oxygen species (ROS) in various cell types. NOX4 is regulated by hypoxia, which can activate its expression and activity.
NOX4 (NADPH oxidase 4) is an enzyme that produces reactive oxygen species (ROS), particularly hydrogen peroxide (H₂O₂).
NOX4 is a cytoplasmic enzyme that catalyzes the transfer of electrons from NADPH to oxygen, resulting in the production of superoxide anion (O2-) and other ROS. NOX4 is expressed in a variety of tissues, including the kidney, lung, and vascular smooth muscle cells.
NOX4 is generally expressed in cancer.
In general, high NOX4 expression is associated with:
      Poor prognosis
      Increased tumor size
      Metastasis
      Resistance to chemotherapy and radiation therapy
      Poor response to treatment
Low NOX4 expression is associated with:
      Better prognosis
      Smaller tumor size
      Less metastasis
      Better response to chemotherapy and radiation therapy
      Better response to treatment

The combination of NOX4-driven ROS and available iron can lead to a synergistic increase in oxidative stress, setting the stage for ferroptotic cell death.

TumCCA↑, A similar S phase cell cycle arrest was also observed for 800 μM HT, and induction of apoptosis also took place after 24 h incubation of HT-29 cells with 600 μM and 800 μM HT

Half-Life↝, HT added to extra virgin olive oil produced a plasma peak of 3.79 ng/mL after 30 min, followed by a rapid decline in HT plasma concentration
BioAv↓, On the basis of these pieces of data, it becomes evident that cytotoxicity and anti-cancer effects of OLE and HT were recorded at concentrations largely exceeding those reachable with diet/olive oil consumption
BioAv↓, Thus, it is difficult to imagine how OLE and HT may be used as cancer-preventive/treating agents if the route of administration is ingestion.
selectivity↑, However, even at high concentrations, OLE and HT seem to be selectively cytotoxic for cancer cells, with no or negligible/minimal effects on non-cancer cells,
RadioS↑, 200 μM OLE enhanced cell radiosensitivity in vitro and in vivo after injection in BALB/C nude mice
*ROS↓, A lot of experimental data in vivo and in vitro have definitively demonstrated the ROS scavenger ability of OLE and HT, which can also act on antioxidant cellular mechanisms restoring ROS homeostasis,
*GSH↑, including promotion of the increase in reduced glutathione levels (GSH), depletion of lipid peroxidation product malondialdehyde (MDA), intensification of the expression and/or activity of detoxicating enzymes SOD, CAT, glutathione-S-transferase (GST
*MDA↓,
*SOD↑,
*Catalase↑,
*NRF2↑, and nuclear factor E2-related factor 2 (Nrf2) upregulation/transactivation,
*chemoP↑, OLE and HT have shown an important ability to mitigate the toxicity elicited by chemotherapeutic agents mainly through their largely demonstrated antioxidant and ROS scavenger activity.
*Inflam↓, OLE and HT exhibit an anti-inflammatory activity that has been demonstrated in multiple in vivo and in vitro models,
PPARγ↑, HT-dependent anti-inflammatory effect was also mediated by HT-elicited increase in protein levels of PPARγ
