Trx2 Cancer Research Results

Trx2, thioredoxin 2: Click to Expand ⟱
Source:
Type:
Trx2 is an essential component of the mitochondrial thioredoxin system, working closely with thioredoxin reductase 2 (TrxR2) to reduce oxidized proteins and protect cells from oxidative stress.
- Mitochondrial thioredoxin (TRX-2).
• By preserving mitochondrial integrity and regulating reactive oxygen species (ROS) levels, Trx2 contributes to cell survival, apoptosis regulation, and metabolic adaptation—all of which are critical in cancer biology.

• Elevated levels of Trx2 may protect tumor cells against oxidative damage, potentially contributing to chemoresistance.
- Overexpression of Trx2 might be associated with more aggressive phenotypes and poorer clinical outcomes, although further studies are needed for definitive prognostic conclusions.

1981- CUR,    Mitochondrial targeted curcumin exhibits anticancer effects through disruption of mitochondrial redox and modulation of TrxR2 activity
- in-vitro, Lung, NA
eff↑, Mitocurcumin, showed 25-50 fold higher efficacy in killing lung cancer cells as compared to curcumin
ROS↑, Mitocurcumin increased the mitochondrial reactive oxygen species (ROS
mt-GSH↓, decreased the mitochondrial glutathione levels
Bax:Bcl2↑, increased BAX to BCL-2 ratio
Cyt‑c↑, cytochrome C release into the cytosol
MMP↓, loss of mitochondrial membrane potential
Casp3↑, increased caspase-3 activity
Trx2↓, mitocurcumin revealed that it binds to the active site of the mitochondrial thioredoxin reductase (TrxR2) with high affinity
TrxR↓, In corroboration with the above finding, mitocurcumin decreased TrxR activity in cell free as well as the cellular system.
mt-DNAdam↑, mitochondrial DNA damage

1973- GamB,    Gambogic acid deactivates cytosolic and mitochondrial thioredoxins by covalent binding to the functional domain
- in-vitro, Liver, SMMC-7721 cell
Apoptosis↑, selectively induces apoptosis in cancer cells, at least partially, by targeting the stress response to reactive oxygen species (ROS).
ROS↑,
Trx↓, deactivates TRX-1/2 proteins by covalent binding to the active cysteine residues in the functional domain via Michael addition reactions.
Trx1↓,
Trx2↓,
Mich↑, can react with small nucleophilic molecules, such as GSH and a cysteine-containing peptide, via a Michael addition reaction.

8006- JG,  VitC,    Juglone-ascorbate treatment enhances reactive oxygen species mediated mitochondrial apoptosis in pancreatic cancer
- in-vitro, PC, PANC1 - in-vitro, PC, Bxpc-3
TumCP↓, Juglone was shown to prevent cell proliferation and induce ROS-mediated mitochondrial apoptosis.
ROS↑,
antiOx⇅, Ascorbate with both antioxidant and oxidant features, shows selective cytotoxicity in cancer cells.
Bcl-2↓, Jug-NaAsc treatment decreased the expressions of antiapoptotic genes Bcl-2 and Birc5 while the apoptotic gene Bax expression increased at all doses.
survivin↓,
BAX↑,
Trx2↓, decreases of Trx2 enzyme levels at all treatments in both cell lines supported gene expression results.
eff↑, Our results suggest that Juglone is a potential anticancer agent especially when combined with ascorbate.
