P450, cytochrome P450 (CYP) family: Click to Expand ⟱

Source:

Type:

The cytochrome P450 (CYP) family includes many isoenzymes that play key roles in metabolizing endogenous substances (like hormones) and xenobiotics (including drugs and toxins). Changes in the expression of these enzymes in various cancers can affect carcinogen activation, drug metabolism, and overall tumor biology, influencing both cancer risk and prognosis.

CYP1B1
– Frequently overexpressed in several cancers including breast, ovarian, prostate, and colorectal cancers.
– Its expression is often low in normal tissues, making it a potential target for selective cancer therapies.

2. CYP3A4 and CYP3A5
These enzymes are highly expressed in the liver, but their expression is also observed in extrahepatic tissues.
– In cancer, CYP3A enzymes can be variably expressed; for instance, CYP3A4 may be upregulated in some liver cancers but downregulated in others.

3. CYP2E1
– CYP2E1 is expressed in the liver and extrahepatic tissues.
– Elevated CYP2E1 activity can lead to increased production of reactive oxygen species (ROS), contributing to DNA damage and cancer progression.

4. CYP19A1 (Aromatase)
– Aromatase converts androgens to estrogens and is expressed in adipose tissue as well as in certain tumors such as breast cancer.
– Its local expression in breast tumors can increase estrogen levels, promoting hormone-dependent tumor growth.

5. CYP2C Family (e.g., CYP2C8, CYP2C9, CYP2C19)
– These enzymes are involved in metabolizing various drugs and are expressed in the liver and intestines.
– Their expression levels can be altered in different tumor types, potentially affecting drug metabolism.

CYP450 enzymes are a large family with diverse roles in cancer biology.
• Their expression in cancers (e.g., CYP1B1, CYP3A4/5, CYP2E1, CYP19A1) has been linked to both the development and progression of tumors, as well as influencing responses to therapy.

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

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 [
MMP↓, ROS generation by PEITC leads to mitochondrial deregulation and modulation of proteins like Bcl2, BID, BIM and BAX, causing the release of cytochrome c into cytosol leading to apoptosis
Cyt‑c↑,

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

*BioAv↑, Urinary levels of both PEITC-NAC and total isothiocyanates (ITC) were significantly elevated in the PEITC treatment periods compared with the placebo periods among all subjects by a magnitude of more than 150 times
*BioAv↑, PEITC is fat soluble. Thus, delivery of PEITC in olive oil avoids concerns about bioavailability;
*BioAv↑, urinary excretion of PEITC equivalents (measured as PEITC-NAC) averaged 13.5 mg in 24 hours in the study participants, which was approximately only one-third the amount of PEITC equivalents (36.6–37.7 mg) excreted
*Dose↝, phase I study with a daily dose of 120 mg PEITC, the maximum amount of PEITC-NAC in the urine was not reached until 2 weeks of daily dosing
Dose↝, watercress consumption is an attractive way to deliver PEITC because of the relatively high concentrations of the PEITC precursor gluconasturtiin in this vegetable, which can be consumed in a more pleasing way than the dosing form used here
