TQ, Thymoquinone: Click to Expand ⟱
Features: Anti-oxidant, anti-tumor
Thymoquinone is a bioactive compound found in the seeds of Nigella sativa, commonly known as black seed or black cumin.
Pathways:
-Cell cycle arrest, apoptosis induction, ROS generation in cancer cells
-inhibit the activation of NF-κB, Suppress the PI3K/Akt signaling cascade
-Inhibit angiogenic factors such as VEGF, MMPs
-Inhibit HDACs, UHRF1, and DNMTs

-Note half-life 3-6hrs.
BioAv low oral bioavailability due to its lipophilic nature. Note refridgeration of Black seed oil improves the stability of TQ.
DIY: ~1 part lecithin : 2–3 parts black seed oil : 4–5 parts warm water. (chat ai)

- Selectivity: Cancer Cells vs Normal Cells

Rank Pathway / Target Axis Direction Label Primary Effect Notes / Cancer Relevance Ref
1 Reactive oxygen species (ROS) ↑ ROS Driver Upstream cytotoxic trigger Primary studies show TQ rapidly increases ROS; antioxidant/ROS modulation attenuates downstream effects, supporting ROS as an initiating mechanism in multiple cancer contexts (ref)
2 Glutathione (GSH) redox buffering ↓ GSH Driver Redox-collapse amplification Same prostate cancer study reports early GSH depletion alongside ROS rise; together these form a redox “one-two punch” that helps explain selective stress in tumor cells (ref)
3 Mitochondrial integrity (ΔΨm) ↓ ΔΨm Driver Mitochondrial dysfunction (MOMP axis) Primary leukemia/cancer study reports disruption of mitochondrial membrane potential after TQ exposure (mitochondrial events central to TQ-mediated death) (ref)
4 Intrinsic apoptosis (caspase-9 → caspase-3; PARP) ↑ caspases / ↑ apoptosis Driver Execution-phase cell death Same primary paper reports activation of caspases (8/9/3) with mitochondrial involvement—core evidence for apoptosis as the major outcome pathway (ref)
5 NF-κB signaling ↓ NF-κB activity Secondary Reduced pro-survival / inflammatory transcription Colon cancer work: TQ induces cell death and chemosensitizes cells by inhibiting NF-κB signaling (explicit pathway-direction support) (ref)
6 STAT3 signaling ↓ p-STAT3 / ↓ STAT3 activation Secondary Reduced survival/proliferation signaling Gastric cancer study explicitly reports TQ suppresses constitutive STAT3 activation and related signaling readouts (ref)
7 NRF2 antioxidant-response axis (NRF2/HO-1 program) ↑ NRF2 pathway (often as stress-response) Adaptive Cellular antioxidant counter-response In TNBC context, a primary study reports TQ upregulates NRF2 (and evaluates downstream immune/checkpoint consequences), consistent with NRF2 acting as an adaptive response to redox stress (ref)
8 HIF-1α hypoxia signaling ↓ HIF-1α protein / ↓ HIF-1α program Adaptive Loss of hypoxia survival signaling Renal cancer hypoxia paper identifies TQ as suppressing HIF-1α and links this to selective killing under hypoxia (ref)
9 Glycolysis / Warburg output (hypoxia-linked) ↓ glycolysis (↓ HIF-1α–mediated glycolytic genes; ↓ glycolytic metabolism) Phenotypic Metabolic suppression In hypoxic renal cancer, TQ suppresses HIF-1α–mediated glycolysis; in CRC, TQ inhibits glycolytic metabolism alongside tumor growth limitation (ref)  |  (ref)


HDAC3, Histone Deacetylase 3: Click to Expand ⟱
Source:
Type:
HDAC3 is an enzyme belonging to the class I histone deacetylases and plays a key role in transcriptional regulation by removing acetyl groups from histone tails.
This deacetylase activity leads to chromatin condensation and generally results in transcriptional repression.
HDAC3 is involved in multiple cellular processes, including cell cycle regulation, apoptosis, and differentiation.

HDAC3 is frequently found to be overexpressed in several cancer types, including breast, colorectal, liver, lung, and hematological malignancies.
Elevated HDAC3 levels have been associated with the repression of tumor suppressor genes and deregulation of proliferative pathways.
