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)

Type: pro-survival proteins
The proteins of BCL-2 family are classified into three subgroups, i.e., the anti-apoptotic/pro-survival proteins represented by BCL-2 and BCL-XL.
BCL-XL overexpressing cells exhibited higher tumors sphere formation capacity and expressed higher levels of some stem cell markers, supporting the concept that BCL-XL plays essential roles in the maintenance of cancer stem cell phenotype.
