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

- 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

Type:

MAPK3 (ERK1)
ERK proteins are kinases that activate other proteins by adding a phosphate group. An overactivation of these proteins causes the cell cycle to stop.
The extracellular signal-regulated kinase (ERK) signaling pathway is a crucial component of the mitogen-activated protein kinase (MAPK) signaling cascade, which plays a significant role in regulating various cellular processes, including proliferation, differentiation, and survival. high levels of phosphorylated ERK (p-ERK) in tumor samples may indicate active ERK signaling and could correlate with aggressive tumor behavior

EEk singaling is frequently activated and is often associated with aggressive tumor behavior, treatment resistance, and poor outcomes.
