CUR, Curcumin: Click to Expand ⟱
Features:
Curcumin is the main active ingredient in Turmeric. 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).

Curcumin — Curcumin is a turmeric-derived polyphenolic curcuminoid and diarylheptanoid from Curcuma longa, functionally best classified as a natural-product small molecule / nutraceutical candidate with pleiotropic redox, inflammatory, transcriptional, metabolic, and chemosensitizing activity. The standard abbreviation is CUR. It is the principal active pigment of turmeric rhizome, usually studied as purified curcumin, curcuminoid mixtures, turmeric extract, phytosomal curcumin, liposomal curcumin, nanoparticle curcumin, or piperine-enhanced formulations. Its oncology relevance is mechanistically broad but clinically constrained by poor aqueous solubility, rapid metabolism, low free systemic exposure, formulation variability, and insufficient well-powered cancer outcome trials.

Primary mechanisms (ranked):

  1. Suppression of NF-κB / STAT3 inflammatory-survival signaling, reducing cytokine, COX-2, iNOS, anti-apoptotic, invasion, and treatment-resistance programs.
  2. Biphasic redox modulation: ROS buffering in normal/inflamed tissue but ROS↑, GSH depletion, thioredoxin reductase disruption, and oxidative stress amplification in susceptible cancer models at sufficient exposure.
  3. Mitochondrial injury and intrinsic apoptosis, including mitochondrial membrane potential loss, cytochrome-c release, caspase activation, PARP cleavage, and ER-stress/UPR involvement.
  4. PI3K/AKT/mTOR and MAPK pathway modulation, contributing to growth arrest, autophagy modulation, apoptosis sensitization, and reduced survival signaling.
  5. Wnt/β-catenin, Hedgehog/GLI, Notch, and cancer-stem-cell suppression, reducing stemness, EMT, invasion, and recurrence-associated phenotypes in models.
  6. Hypoxia / HIF-1α and glycolysis inhibition, including reduced GLUT1, HK2, LDHA, PKM2, lactate/ECAR, and Warburg-like metabolic support in selected models.
  7. Anti-angiogenic and anti-metastatic modulation, including VEGF, MMPs, uPA, CXCR4/SDF-1, TGF-β/α-SMA, FAK, and EMT-related axes.
  8. Epigenetic and transcriptional reprogramming, including reported HDAC, DNMT, EZH2, Sp-family, p53, and microRNA-related effects.
  9. NRF2 modulation: generally cytoprotective in normal cells but potentially protective for cancer cells when NRF2 is activated; NRF2 suppression/knockdown can increase curcumin-induced ROS stress in some tumor models.
  10. Chemosensitization and radiosensitization, with parallel normal-tissue protective signals reported in some mucositis, dermatitis, oxidative-stress, and radioprotection contexts.

Bioavailability / PK relevance: Conventional oral curcumin has poor systemic bioavailability because of low solubility, low absorption, rapid conjugation, and rapid elimination. Oral trials have used doses up to gram-level daily dosing, but circulating free curcumin is typically low; measured plasma exposure often reflects conjugated curcumin. Piperine, phospholipid/phytosome, micellar, liposomal, nanoparticle, and other enhanced formulations can raise exposure, but each formulation should be treated as a distinct translational entity. Delivery constraints are central for oncology interpretation.

In-vitro vs systemic exposure relevance: Common in-vitro anticancer concentrations, often in the low-to-mid micromolar range and sometimes higher, frequently exceed achievable free plasma exposure from standard oral curcumin. Therefore, direct systemic anticancer claims from cell culture should be weighted cautiously unless supported by tissue-local exposure, enhanced formulation data, local delivery, IV/liposomal delivery, or clinically measured pharmacodynamic biomarkers.

Clinical evidence status: Preclinical evidence is extensive; human oncology evidence is mainly small human, biomarker, pilot, chemoprevention, adjunctive, symptom-management, and formulation trials. Current authoritative oncology summaries judge evidence inadequate to recommend curcumin-containing products as cancer treatment or as routine adjunct anticancer therapy, although symptom-support areas such as oral mucositis, radiation dermatitis, oxidative-status measures, and quality of life have more suggestive but still confirmatory-level evidence.


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.

HDAC, Histone deacetylases: Click to Expand ⟱
Source:
Type:
Enzymes involved in regulating gene expression by removing acetyl groups from histones, the proteins around which DNA is wrapped.
-Many cancers exhibit altered expression levels of HDACs, which can contribute to the dysregulation of genes involved in cell growth, survival, and differentiation.
-HDACs can repress the expression of tumor suppressor genes, leading to uncontrolled cell proliferation and survival. This repression can be a key factor in the development and progression of cancer.
-HDAC inhibitors (HDACi) have been developed and are being investigated for their ability to reactivate silenced genes, induce cell cycle arrest, and promote apoptosis in cancer cells.
-HDAC1, HDAC2): Often overexpressed in various cancers, including breast, prostate, and colorectal cancers. Their overexpression is associated with poor prognosis.
-HDAC4, HDAC5): These may have both oncogenic and tumor-suppressive roles depending on the context and cancer type.
-While HDACs are not classified as traditional oncogenes, their overexpression and activity can contribute to oncogenic processes.
-HDAC inhibitor works by preventing the removal of acetyl groups from histones, thereby modulating gene expression, influencing cell behavior, and potentially reversing aberrant gene silencing seen in various diseases.
-HDAC inhibitors can help reactivate these genes, thereby inhibiting growth and inducing apoptosis in cancer cells.
