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)


E2Fs, E2F family of transcription factors: Click to Expand ⟱
Source: HalifaxProj(inactivate)
Type:
E2Fs have been classified as transcriptional activators (E2F1-3) or transcriptional repressors (E2F4-8), and are thus predicted to play a dual role in human cancers.
Activators: E2F1,2,3a,3b
Repressors: E2F4,5,6,7a,7b,8
As a tumor suppressor and oncogene, the transcription factor E2F1 is a downstream regulator of the Rb pathway.
The role of E2Fs in CSCs is widely regarded as an activator gene. Up-regulation of E2Fs is reported to be involved in proliferation promotion (21), maintenance and acquisition of self-renewal (22, 23), invasion and metastatic progression (24) and resistance to chemotherapy and radiotherapy (25) in many CSCs.
