Curcumin / chemoPv Cancer Research Results

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
curcumin can act as a pro-oxidant when blue light is applied

- Selectivity: Cancer Cells vs Normal Cells

Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Driver Suppression of survival and inflammatory transcription NF-κB is a primary, repeatedly validated curcumin target explaining pleiotropic downstream effects
2 STAT3 signaling ↓ STAT3 phosphorylation / activity ↔ or mild suppression Driver Loss of pro-survival and proliferative signaling STAT3 inhibition contributes to growth arrest, apoptosis sensitization, and reduced cytokine signaling in tumors
3 Reactive oxygen species (ROS) ↑ ROS (dose- & context-dependent) ↓ ROS / buffered Conditional Driver Biphasic redox modulation Curcumin can act as a pro-oxidant in cancer cells with high basal stress while acting antioxidant in normal cells
4 Mitochondrial integrity / intrinsic apoptosis ↓ ΔΨm; ↑ caspase activation ↔ preserved Driver Execution of intrinsic apoptosis Mitochondrial dysfunction and caspase activation occur downstream of NF-κB/STAT3 and ROS effects
5 PI3K → AKT → mTOR axis ↓ AKT / ↓ mTOR ↔ or adaptive suppression Secondary Reduced growth and anabolic signaling AKT/mTOR inhibition contributes to growth suppression and autophagy induction in cancer cells
6 Autophagy ↑ autophagy (protective or pro-death) ↑ adaptive autophagy Secondary Stress adaptation vs cell death Autophagy may be cytoprotective or cooperate with apoptosis depending on context and dose
7 HIF-1α / VEGF hypoxia–angiogenesis axis ↓ HIF-1α; ↓ VEGF ↔ minimal effect Secondary Anti-angiogenic pressure Suppression of hypoxia-driven transcription limits angiogenesis and tumor adaptation
8 Cell cycle regulation ↑ G2/M or G1 arrest ↔ largely spared Phenotypic Cytostatic growth control Cell-cycle arrest reflects upstream signaling and epigenetic effects rather than direct CDK inhibition
9 Migration / invasion (EMT, MMP axis) ↓ migration & invasion ↔ Phenotypic Anti-metastatic phenotype Reduced EMT markers and protease activity limit invasive behavior
10 Epigenetic regulation (p300/CBP HAT activity) ↓ histone acetylation ↔ modest Secondary Transcriptional reprogramming Curcumin modulates chromatin via HAT inhibition rather than classic HDAC inhibition
