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

- 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:
Caspases are a cysteine protease that speed up a chemical reaction via pointing their target substrates following an aspartic acid residue.1 They are grouped into apoptotic (caspase-2, 3, 6, 7, 8, 9 and 10) and inflammatory (caspase-1, 4, 5, 11 and 12) mediated caspases.
Caspase-1 may have both tumorigenic or antitumorigenic effects on cancer development and progression, but it depends on the type of inflammasome, methodology, and cancer.
Catalase is an enzyme found in nearly all living cells exposed to oxygen. Its primary role is to protect cells from oxidative damage by catalyzing the conversion of hydrogen peroxide (H₂O₂), a potentially damaging byproduct of metabolism, into water (H₂O) and oxygen (O₂). This detoxification process is crucial because excess H₂O₂ can lead to the formation of reactive oxygen species (ROS) that damage proteins, lipids, and DNA.

Catalase and Cancer
Oxidative Stress and Cancer:
Cancer cells often experience increased levels of oxidative stress due to rapid proliferation and metabolic changes. This stress can lead to DNA damage, promoting tumorigenesis.
Catalase helps mitigate oxidative stress, and its expression can influence the survival and proliferation of cancer cells.
Expression Levels in Different Cancers:
Overexpression: In some cancers, such as breast cancer and certain types of leukemia, catalase may be overexpressed. This overexpression can help cancer cells survive in oxidative environments, potentially leading to more aggressive tumor behavior.
Downregulation: Conversely, in other cancers, such as colorectal cancer, reduced catalase expression has been observed. This downregulation can lead to increased oxidative stress, contributing to tumor progression and metastasis.
Prognostic Implications:
Survival Rates: Studies have shown that high levels of catalase expression can be associated with poor prognosis in certain cancers, as it may enable cancer cells to resist apoptosis (programmed cell death) induced by oxidative stress.

Some types of cancer cells have been reported to exhibit lower catalase activity, possibly increasing their vulnerability to oxidative damage under certain conditions. This vulnerability has even been exploited in some therapeutic strategies (for example, approaches that generate excess H₂O₂ or other ROS specifically targeting cancer cells have been researched).
