Features:
Natural compound found in apples and rosemary.
Ursolic acid (UA) is a pentacyclic triterpenoid found in many plants (notably apple peel, rosemary, thyme, holy basil, and other herbs). In cancer models it is best described as a multi-target signaling modulator with prominent effects on NF-κB inflammation/survival transcription, STAT3, PI3K/AKT/mTOR, and MAPK pathways, with downstream outcomes including cell-cycle arrest, apoptosis, anti-angiogenesis, and reduced invasion/EMT. A practical translational constraint is poor aqueous solubility and low oral bioavailability, so many strong in-vitro µM effects may not map cleanly to typical oral exposure without formulation.

Rank Pathway / Axis Cancer Cells Normal Cells TSF Primary Effect Notes / Interpretation
1 NF-κB inflammatory / survival transcription NF-κB ↓; COX-2/iNOS/cytokines/Bcl-2 family/MMPs ↓ (reported) Inflammation tone ↓ (context) R, G Anti-inflammatory + anti-survival transcription One of the most frequently reported UA effects across tumor models; downstream impacts include reduced pro-survival and pro-metastatic gene programs.
2 STAT3 axis (JAK/STAT3 signaling) STAT3 activity ↓ (reported); downstream targets ↓ R, G Oncogenic transcription suppression UA is often reported to suppress STAT3 signaling, contributing to reduced proliferation/survival signaling.
3 PI3K → AKT (± mTOR) survival axis PI3K/AKT ↓; mTORC1 tone ↓ (reported; model-dependent) R, G Growth/survival modulation Commonly listed mechanism; direction and strength vary by cell line and exposure.
4 MAPK re-wiring (ERK / JNK / p38) Stress-MAPK modulation (context-dependent) P, R, G Signal reprogramming JNK/p38 activation and ERK modulation are reported variably; avoid fixed arrows unless tied to a specific model.
5 Cell-cycle checkpoints (Cyclins/CDKs; p21/p27) Cell-cycle arrest ↑ (G1/S or G2/M; reported); Cyclin D1/CDKs ↓ (context) G Cytostasis Often downstream of NF-κB/STAT3/PI3K signaling suppression.
6 Intrinsic apoptosis (mitochondrial/caspase linked) Apoptosis ↑; Bax ↑; Bcl-2 ↓; caspases ↑ (reported) ↔ (generally less activation) G Cell death execution Common downstream endpoint; can be coupled to stress signaling and survival pathway suppression.
7 Angiogenesis signaling (VEGF / HIF-1α outputs) VEGF ↓; angiogenic outputs ↓ (reported) G Anti-angiogenic support Typically phenotype-level effects tied to NF-κB/PI3K/HIF programs.
8 Invasion / metastasis programs (MMPs / EMT) MMP2/MMP9 ↓; EMT markers ↓; migration/invasion ↓ (reported) G Anti-invasive phenotype Often downstream of NF-κB/STAT3 changes; not universal across all tumors.
9 ROS / redox modulation ROS direction variable; redox stress or buffering reported (context) Oxidative injury ↓ in some non-tumor stress models P, R, G Stress modulation UA is not a reliable “pro-oxidant killer”; redox effects depend on dose, model, and baseline oxidative state.
10 Bioavailability / formulation constraint Systemic exposure often limited (poor solubility) Translation constraint UA is highly lipophilic with poor aqueous solubility; many formulations (e.g., nanoparticles, phospholipid complexes) are explored to improve exposure.

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

  • P: 0–30 min (rapid signaling interactions)
  • R: 30 min–3 hr (acute stress-response + transcription signaling shifts)
  • G: >3 hr (gene-regulatory adaptation and phenotype-level outcomes)


STAT3, Signal transducer and activator of transcription 3: Click to Expand ⟱
Source:
Type: Oncogene
Stat3 (Signal Transducer and Activator of Transcription 3) is a transcription factor that plays a crucial role in various cellular processes, including cell growth, survival, differentiation, and immune response.
Stat3 is frequently found to be constitutively activated in many types of cancers, including breast, prostate, lung, and head and neck cancers. (associated with poor prognosis and reduced survival.)

-STAT3 is typically activated by cytokines (such as IL-6) and growth factors binding to their respective receptors.
-Activated STAT3 upregulates the expression of genes that promote cell cycle progression (e.g., cyclin D1) and anti-apoptotic proteins (e.g., Bcl-2, Bcl-xL).
