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)

Mitochondrial respiration plays a crucial role in the development and progression of cancer. Cancer cells often exhibit altered metabolic profiles, including changes in mitochondrial respiration, to support their rapid growth and proliferation.

In cancer cells, mitochondrial respiration is often downregulated, and instead, they rely on glycolysis for energy production, even in the presence of oxygen. This phenomenon is known as the "Warburg effect."

There are several key players involved in the regulation of mitochondrial respiration in cancer cells, including:

Pyruvate dehydrogenase (PDH): a critical enzyme that converts pyruvate into acetyl-CoA, which is then fed into the citric acid cycle.
Citrate synthase: an enzyme that catalyzes the first step of the citric acid cycle.
Succinate dehydrogenase (SDH): an enzyme that participates in both the citric acid cycle and the electron transport chain.
Cytochrome c oxidase (COX): the final enzyme in the electron transport chain, responsible for generating ATP.
Alterations in the expression and activity of these enzymes can impact mitochondrial respiration in cancer cells. For example, increased expression of PDH and citrate synthase can enhance mitochondrial respiration, while decreased expression of SDH and COX can impair it.

Additionally, various transcription factors and signaling pathways regulate mitochondrial respiration in cancer cells, including:

HIF-1α (hypoxia-inducible factor 1 alpha): a transcription factor that promotes glycolysis and suppresses mitochondrial respiration in response to hypoxia.
c-Myc: a transcription factor that regulates the expression of genes involved in mitochondrial respiration and biogenesis.
PI3K/Akt/mTOR: a signaling pathway that promotes cell growth and proliferation, in part by regulating mitochondrial respiration.
