CHr, Chrysin: Click to Expand ⟱

Features:

Chrysin is found in passion flower and honey. It is a flavonoid.
-To reach plasma levels that might more closely match the concentrations used in in vitro studies (typically micromolar), considerably high doses or advanced delivery mechanisms would be necessary.
Chrysin is widely summarized as modulating PI3K/Akt and MAPK pathways in cancer.

-Note half-life 2 hrs, BioAv very poor often <1%

- Selectivity: Cancer Cells vs Normal Cells

Rank	Pathway / Axis	Cancer Cells	Normal Cells	TSF	Primary Effect	Notes / Interpretation
1	PI3K → AKT (± mTOR) survival axis	↓ PI3K/AKT (often ↓ p-AKT; downstream growth signals ↓)	↔	R, G	Growth/survival suppression	Frequently reported hub effect; contributes to reduced proliferation and sensitization to stress/apoptosis programs.
2	Intrinsic apoptosis (p53/Bcl-2 family → caspase-9/3)	↑ p53 axis (context); Bax↑/Bcl-2↓; ↑ caspase-9/3; apoptosis ↑	↔ (generally less activation)	G	Apoptosis execution	Common endpoint across many tumor models; often downstream of survival-pathway suppression and stress signaling.
3	ER stress / UPR (PERK and related arms)	ER stress ↑; UPR activation ↑	↔	R, G	Stress-to-death coupling	ER stress has been directly shown in chrysin-treated cancer cells and can couple to apoptosis.
4	JAK / STAT3 signaling	↓ STAT3 signaling (context)	↔	R, G	Anti-survival transcription	STAT3 inhibition is reported in cancer models and often aligns with reduced proliferation and increased apoptosis.
5	ROS / oxidative stress (context-dependent)	ROS modulation (often ↑ mitochondrial ROS in tumor models)	↔ / antioxidant behavior in some contexts	P, R, G	Stress amplifier (variable)	Direction depends on dose/model; avoid absolute “ROS always ↑/↓”. Oxidative stress + DDR has been linked to anti-angiogenic effects in vivo in melanoma models.
6	MAPK re-wiring (ERK / JNK / p38)	MAPK shifts; JNK/p38 often stress-activated; ERK variable	↔	P, R, G	Signal reprogramming	MAPK effects differ by cell line; chrysin can suppress JNK/ERK signaling to reduce MMP-9 in some models.
7	Cell-cycle arrest / proliferation control	Cell-cycle arrest ↑; proliferation ↓	↔	G	Cytostasis	Often observed as later phenotype-level outcomes, downstream of signaling changes.
8	Invasion / metastasis (MMP-9; EMT programs)	MMP-9 ↓; migration/invasion ↓ (context)	↔	G	Anti-invasive phenotype	Chrysin can reduce MMP-9 expression via AP-1 suppression and MAPK pathway effects in certain cancer models.
9	Angiogenesis (VEGF/angiogenic outputs)	Angiogenesis outputs ↓ (context)	↔	G	Anti-angiogenic support	In melanoma models, chrysin has been associated with angiogenesis regression linked to oxidative stress and DNA damage response.
10	Bioavailability constraint (oral PK limitation)	Systemic exposure often low without formulation	—	—	Translation constraint	Native chrysin oral bioavailability is extremely low due to poor solubility and extensive glucuronidation/sulfation with efflux; formulation strategies are commonly required for systemic effects.

Time-Scale Flag (TSF): P / R / G

P: 0–30 min (primary/physical–chemical effects; rapid signaling / phosphorylation shifts)
R: 30 min–3 hr (acute stress-response and redox signaling)
G: >3 hr (gene-regulatory adaptation and phenotype-level outcomes)

TrxR, Thioredoxin Reductase: Click to Expand ⟱

Source:

Type:

TrxR is an enzyme that reduces Trx, allowing it to perform its reducing functions. It has been shown to have a role in cancer cell metabolism and survival.
TrxR is overexpressed in various types of cancer, including breast, lung, colon, and prostate cancer.

- Part of the thioredoxin system, which regulates reactive oxygen species (ROS).
- TrxR is a major antioxidant systems that maintains the intracellular redox homeostasis.
- Inhibition causes an increase in ROS.
- TrxR is often upregulated in cancer cells to help manage increased oxidative stress, it is seen as a potential therapeutic target. Inhibiting TrxR may result in increased ROS in cancer cells, pushing them toward apoptosis.
- TrxR is a selenoprotein—meaning it incorporates the trace element selenium in the form of the amino acid selenocysteine.

TrxR inhibitors:
-Piperlongumine
-Withania somnifera (Ashwagandha)
-Parthenolide
-EGCG
-Curcumin
-Myricetin
-Gambogic Acid
