GPx, Glutathione peroxidases: Click to Expand ⟱

Source:

Type:

Glutathione peroxidases (GPXs) are crucial antioxidant enzymes, counteracting reactive oxygen species (ROS).
Glutathione peroxidase (GPx) refers to a family of antioxidant enzymes that play a crucial role in protecting cells from oxidative stress by catalyzing the reduction of hydrogen peroxide and organic peroxides. There are several isoforms of GPx, including GPx1, GPx2, GPx3, and GPx4, each with distinct tissue distributions and functions.
GPX overexpression promotes proliferation and invasion in cancer cells. Glutathione peroxidase-1 (GPX1), the most abundant isoform, contributes to invasion, migration, cisplatin resistance, and proliferation in various cancers.

GPx expression is often elevated in various cancers and is generally associated with poorer prognosis due to its role in protecting cancer cells from oxidative stress and contributing to treatment resistance.

PEITC,

Selective killing of oncogenically transformed cells through a ROS-mediated mechanism by β-phenylethyl isothiocyanate

vitro+vivo,

Ovarian,

SKOV3

 5 μM

ROS↑, Here, we show that such abnormal increases in ROS can be exploited to selectively kill cancer cells using β-phenylethyl isothiocyanate (PEITC).
GSH↓, malignant cells highly sensitive to PEITC, which effectively disables the glutathione antioxidant system and causes severe ROS accumulation preferentially in the transformed cells due to their active ROS output
selectivity↑, Our study showed that PEITC has a superior selectivity compared to cisplatin. The ability to preferentially kill malignant cells is a promising feature of PEITC.
mtDam↑, Excessive ROS causes oxidative mitochondrial damage, inactivation of redox-sensitive molecules, and massive cell death.
TumCD↑,
OS↑, In vivo, PEITC exhibits therapeutic activity and prolongs animal survival.
eff↑, Furthermore, because PEITC has low toxicity in nonmalignant cells and exhibits anticancer selectivity superior to cisplatin,
*toxicity↓,
H2O2↑, t ROS induced by PEITC were mainly DCF-DA-reactive species such as hydrogen peroxide (H2O2) and nitric oxide (NO)
NO↑,
eff↓, 5 μM PEITC significantly increased DAF-FM fluorescence, which was reversed by the antioxidant N-acetyl-L-cysteine (NAC) but not by the H2O2-scavenging enzyme catalase
GPx↓, 500 μM PEITC inhibited GPX by approximately 50% and 90%, respectively. These concentrations could be achieved intracellularly when cells were incubated with 5–10 μM PEITC.
Dose↝, Interestingly, incubation of cells with 5–10 μM PEITC led to a depletion of cellular GSH, which is in the mM range. The explanation for this stoichiometric discrepancy is that PEITC can be concentrated in the cells. A
eff↑, combination of PEITC with curcumin was effective, suggesting that combination of PEITC with other agents may enhance anticancer activity.

PL,

Piperlongumine rapidly induces the death of human pancreatic cancer cells mainly through the induction of ferroptosis

in-vitro,

PC,

ROS↑, Piperlongumine (PL) is a natural product with cytotoxic properties restricted to cancer cells by significantly increasing intracellular reactive oxygen species (ROS) levels.
Ferroptosis↓, at least in part, the induction of ferroptosis,. requires the accumulation of ROS in an iron-dependent manner
GSH↓, Since we actually found that PL markedly depleted GSH (Fig. 1H), these results suggest that PL may inhibit GPX activity.
GPx↓,
cl‑PARP∅, PL did not induce the expression of typical apoptotic markers, such as cleaved PARP and cleaved caspase-3
cl‑Casp3∅,
eff↑, PL (15 uM) plus CN-A resulted in a further increase in the population of ROS-positive cells
eff↑, SSZ enhances the PL-induced ferroptotic death of pancreatic cancer cells.

Review,

IBD,

*Imm↑, Selenium is essential for the maintenance of the immune system, conversion of thyroid hormones, protection against the harmful action of heavy metals and xenobiotics as well as for the reduction of the risk of chronic diseases
*GutMicro↑, Selenium is able to balance the microbial flora avoiding health damage associated with dysbiosis.
*BioAv↑, highlighting their role in improving the bioavailability of selenocompounds
*Risk↓, Selenium deficiency may result in a phenotype of gut microbiota that is more susceptible to cancer, thyroid dysfunctions, inflammatory bowel disease, and cardiovascular disorders.
*Dose↝, highest sources of Se with concentrations that range from 1.80 to 320.80 μg Se/g
Risk↓, serum Se greater than or equal to 135 μg/L were associated with reduced cancer mortality
