Type: protein

Manganese superoxide dismutase (MnSOD, also known as SOD2).
SOD2 (Superoxide Dismutase 2) is a protein that is a member of the superoxide dismutase family of enzymes, which are involved in the detoxification of superoxide radicals.

-MnSOD is localized in the mitochondria and plays a key role in detoxifying superoxide radicals, thereby limiting oxidative damage and maintaining mitochondrial integrity.
• By modulating ROS levels, MnSOD influences cellular signaling pathways involved in proliferation, apoptosis, and metabolic adaptation—all of which are critical during tumorigenesis.

Typically low SOD2 expression in cancers, with poor prognosis.

-Increased MnSOD levels may help tumor cells manage the high levels of ROS resulting from rapid cell division and metabolic alterations, which can contribute to tumor progression.
- Some prognostic studies associate high levels of MnSOD with resistance to apoptosis and poorer patient outcomes; however, findings are not entirely consistent across all studies.

• Depending on the tumor type and the balance with other antioxidant systems, high MnSOD can be associated with either favorable or unfavorable clinical outcomes, reflecting its dual roles in cancer biology.

PEITC,

Phenethyl Isothiocyanate: A comprehensive review of anti-cancer mechanisms

Review,

Var,

Risk↓, strong inverse relationship between dietary intake of cruciferous vegetables and the incidence of cancer.
AntiCan↑, Phenethyl isothiocyanate (PEITC) is present as gluconasturtiin in many cruciferous vegetables with remarkable anti-cancer effects.
TumCP↓, PEITC targets multiple proteins to suppress various cancer-promoting mechanisms such as cell proliferation, progression and metastasis
TumMeta↓,
ChemoSen↑, combination of PEITC with conventional anti-cancer agents is also highly effective in improving overall efficacy
*BioAv↑, ITCs are released from glucosinolates by the action of the enzyme myrosinase. The enzyme myrosinase can be activated by cutting or chewing the vegetables, but heating can destroy its activity
*other↝, Although water cress and broccoli are known to be the richest source, PEITC can also be obtained from turnips and radish
*Dose↝, In a study conducted with human volunteers, approximately 2 to 6 mg of PEITC was found to be released by the consumption of one ounce of watercress
Dose↓, significant anti-cancer effects can be achieved at micromolar concentrations of PEITC.
*BioAv↑, PEITC is highly bioavailable after oral administration. A single dose of 10–100 μmol/kg PEITC in rats resulted in bioavailability ranging between 90–114%
*Dose↝, Furthermore, about 928.5±250nM peak plasma concentration of PEITC was achieved in human subjects, after the consumption of 100g watercress.
*Half-Life↝, time to reach peak plasma concentration was observed to be 2.6h±1.1h with a t1/2 4.9±1.1h
*toxicity↝, long term studies are required to establish the safety profile of PEITC, since regular intake of PEITC can cause its accumulation resulting in cumulative effects, which could be toxic.
GSH↓, The conjugation of PEITC with intracellular glutathione and the subsequent removal of the conjugate result in depletion of glutathione and alteration in redox homeostasis leading to oxidative stress
ROS↑, PEITC-mediated generation of reactive oxygen species (ROS) is known to be a general mechanism of action leading to cytotoxic effects, especially specific to cancer cells
CYP1A1↑, PEITC on one hand causes induction of CYP1A1 and CYP1A2; however, it inhibits activity of certain CytP450 enzymes, such as CYP2E1, CYP3A4 and CYP2A3
CYP1A2↑,
P450↓,

*GPx1↑,
*SOD1↑,
*SOD2↑,
Akt↓, PEITC inhibits Akt, a component of Ras signaling to inhibit tumor growth in several cancer types
EGFR↓, PEITC is also known to inhibit EGFR and HER2, which are important growth factors and regulators of Akt in different cancer models
HER2/EBBR2↓,
P53↑, PEITC-mediated activation of another tumor suppressor, p53 was observed in oral squamous cell carcinoma, causing G0/G1 phase arrest in multiple myeloma,
Telomerase↓, PEITC has been shown to inhibit telomerase activity in prostate and cervical cancer cells
selectivity↑, generation of reactive oxygen species (ROS), which also has been shown to be the basis of selectivity of PEITC toward cancer cells leaving normal cells undamaged [

DR4↑, induction of death receptors and Fas-mediated apoptosis
Fas↑,
XIAP↓, PEITC-mediated suppression of anti-apoptotic proteins like XIAP and survivin, which are up-regulated in cancer cells

angioG↓, is possible that PEITC can block angiogenesis by non-hypoxic mechanisms also.
MMPs↓, Various studies with PEITC have shown suppression of invasion through inhibition of matrix metalloproteinases along with anti-metastatic effects caused by suppression of ERK kinase activity and transcriptional activity of NFkB
ERK↓,
NF-kB↓,
EMT↓, PEITC was also known to inhibit processes, such as epithelial to mesenchymal transition (EMT), cell invasion and migration, which are essential pre-requisites for metastasis
TumCI↓,
TumCMig↓,
Glycolysis↓, reduced rates of glycolysis in PEITC-treated cells and depletion of ATP lead to death in prostate cancer cells
ATP↓,
selectivity↑, PEITC (5μM) treatment suppressed glycolysis in the cancer cells, but no changes were observed in normal cells.
*antiOx↑, the antioxidant effect is achieved at very low ITC levels in normal cells as shown in various animal models
Dose↝, At higher concentrations, ITCs may generate ROS by depleting antioxidant levels. PEITC is known to cause ROS generation, which is the major mechanism of toxicity in cancer cells
other↝, There is a continuous leakage of electrons from the electron transport chain (ETC), which is major source of ROS production. PEITC causes generation of endogenous ROS by disrupting mitochondrial respiratory chain
OCR↓, PEITC also inhibits mitochondrial complex III activity and reduces the oxygen consumption rate in prostate cancer cells
GSH↓, PEITC binds to GSH and causes its depletion in cancer cells leading to ROS-induced cell damage
ITGB1↓, PEITC was found to inhibit major integrins, such as ITGB1, ITGA2 and ITGA6 in prostate cancer cells
ITGB6↓,
ChemoSen↑, Using pre-clinical studies, improved outcomes were observed when the conventional agents, such as docetaxel, metformin, vinblastine, doxorubicin and HDAC inhibitors were combined with PEITC
