CUR, Curcumin: Click to Expand ⟱
Features:
Curcumin is the main active ingredient in Tumeric. Member of the ginger family.Curcumin is a polyphenol extracted from turmeric with anti-inflammatory and antioxidant properties.
- Has iron-chelating, iron-chelating properties. Ferritin. But still known to increase Iron in Cancer cells.
- GSH depletion in cancer cells, exhaustion of the antioxidant defense system. But still raises GSH↑ in normal cells.
- Higher concentrations (5-10 μM) of curcumin induce autophagy and ROS production
- Inhibition of TrxR, shifting the enzyme from an antioxidant to a prooxidant
- Strong inhibitor of Glo-I, , causes depletion of cellular ATP and GSH
- Curcumin has been found to act as an activator of Nrf2, (maybe bad in cancer cells?), hence could be combined with Nrf2 knockdown
-may suppress CSC: suppresses self-renewal and pathways (Wnt/Notch/Hedgehog).
Clinical studies testing curcumin in cancer patients have used a range of dosages, often between 500 mg and 8 g per day; however, many studies note that doses on the lower end may not achieve sufficient plasma concentrations for a therapeutic anticancer effect in humans.
• Formulations designed to improve curcumin absorption (like curcumin combined with piperine, nanoparticle formulations, or liposomal curcumin) are often employed in clinical trials to enhance its bioavailability.

-Note half-life 6 hrs.
BioAv is poor, use piperine or other enhancers
Pathways:
- induce ROS production at high concentration. Lowers ROS at lower concentrations
- ROS↑ related: MMP↓(ΔΨm), ER Stress↑, UPR↑, GRP78↑, Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑, HSP↓
- Lowers AntiOxidant defense in Cancer Cells: GSH↓ Catalase↓ HO1↓ GPx↓

2811- CUR,    Effect of Curcumin Supplementation During Radiotherapy on Oxidative Status of Patients with Prostate Cancer: A Double Blinded, Randomized, Placebo-Controlled Study
- Human, Pca, NA
*antiOx↑, Curcumin is an antioxidant agent with both radiosensitizing and radioprotective properties
radioP↑,
RadioS∅, In the present study we have failed to observe any radiosensitizing or prooxidant feature for curcumin in the prescribed dose;
*TAC↑, The present study showed that curcumin can increase TAC and decrease SOD activity in the plasma of patients with prostate cancer receiving radiotherapy; these observations are thought to be possibly brought about by the antioxidant effect of curcumin
*SOD↓, 3 mo after completion of radiotherapy, TAC increased significantly (P < 0.001) and the activity of SOD decreased significantly

1485- CUR,  Chemo,  Rad,    Curcumin, the golden spice from Indian saffron, is a chemosensitizer and radiosensitizer for tumors and chemoprotector and radioprotector for normal organs
- Review, Var, NA
ChemoSen↑, Such effects of curcumin were due to its ability to sensitize cancer cells for increased production of ROS
NF-kB↓, it downregulates various growth regulatory pathways and specific genetic targets including genes for NF-κB, STAT3, COX2, Akt
*STAT3↓, curcumin acts as a chemosensitizer and radiosensitizer has also been studied extensively. For example, it downregulates various growth regulatory pathways and specific genetic targets including genes for NF-kB, STAT3, COX2, Akt,
*COX2↓,
*Akt↓,
*NRF2↑, The protective effects of curcumin appear to be mediated through its ability to induce the activation of NRF2 and induce the expression of antioxidant enzymes (e.g., hemeoxygenase-1, glutathione peroxidase
*HO-1↑,
*GPx↑,
*NADPH↑,
*GSH↑, increase glutathione (a product of the modulatory subunit of gamma-glutamyl-cysteine ligase)
*ROS↓, dietary curcumin can inhibit chemotherapy-induced apoptosis via inhibition of ROS generation and blocking JNK signaling
*p300↓, inhibit p300 HAT activity
radioP↑, radioprotector for normal organs
chemoP↑, curcumin has also been shown to protect normal organs such as liver, kidney, oral mucosa, and heart from chemotherapy and radiotherapy-induced toxicity.
