Rank Pathway / Axis Cancer Cells Normal Cells TSF Primary Effect Notes / Interpretation
1 Intrinsic apoptosis (mitochondrial-mediated) ↑ mitochondria depolarization; ↑ cytochrome-c; ↑ caspase-9/3 activation ↔ limited activation (higher exposure required) R, G Execution of apoptosis Betulinic acid (BA) is well known to engage the intrinsic apoptotic cascade, typically downstream of redox and signaling perturbations.
2 ROS / redox stress ↑ ROS (P→R) ↔ basal or antioxidant adaptation in some contexts P, R Stress induction Many studies report ROS elevation in tumor cells exposed to BA; the direction and magnitude vary by cell type and exposure.
3 Mitochondrial permeability transition / ΔΨm loss ΔΨm ↓ (R→G) ↔ maintained R, G Mitochondrial failure Often observed as an early event preceding caspase activation in apoptosis studies.
4 PI3K / AKT / mTOR survival axis ↓ PI3K/AKT signaling; ↓ phospho-mTOR ↔ R, G Survival/growth suppression Betulinic acid often downregulates pro-survival kinase signaling, sensitizing cells to apoptosis and cytostasis.
5 NF-κB signaling ↓ NF-κB activity ↔ R, G Pro-survival/inflammatory transcription suppression Reduction in NF-κB activity limits pro-survival gene expression; supports sensitization to stressors.
6 MAPK re-wiring (JNK / ERK / p38) Stress-MAPK shifts; JNK/p38 often ↑; ERK context-dependent ↔ P, R Early stress signaling MAPK responses vary by model, with stress-associated p38/JNK often activated and ERK modulation variable.
7 Cell-cycle checkpoints (p21, p27, cyclins) ↑ p21/p27; ↑ G1/S or G2/M arrest ↔ G Proliferation arrest BA often induces cell-cycle blockade, slowing proliferation before apoptosis commitment.
8 Angiogenic signaling (VEGF & related) ↓ VEGF; anti-angiogenic outputs ↔ G Anti-angiogenic support Typically seen at the level of reduced pro-angiogenic factor expression or secretion in longer-term assays.
9 EMT / invasion / migration programs (MMPs) ↓ MMP2/MMP9; ↓ migration/invasion ↔ G Anti-invasive phenotype Often measured as reduced invasive capacity and decreased expression of EMT markers in later time points.
10 Autophagy modulation ↑ LC3-II; ↑ autophagic flux (model dependent) ↔ G Adaptive clearance / cell fate shift BA can modulate autophagy, which may either sensitize cells to death pathways or reflect adaptive stress responses.

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

  • P: 0–30 min (primary/physical-chemical effects; rapid kinase/redox signaling)
  • R: 30 min–3 hr (acute redox and stress-response activation)
  • G: >3 hr (gene-regulatory adaptation and phenotypic outcomes)
ECAR, Extracellular Acidification Rate: Click to Expand ⟱

Type:
ECAR (Extracellular Acidification Rate) is a measure of the rate at which cells release acidic byproducts, such as lactic acid, into the extracellular environment. In the context of cancer, ECAR is often used as a proxy for glycolytic activity, as cancer cells often exhibit increased glycolysis, even in the presence of oxygen.

Studies have shown that cancer cells often have a higher ECAR compared to normal cells, indicating that they are producing more acidic byproducts. This is thought to be due to the fact that cancer cells often rely more heavily on glycolysis for energy production, even in the presence of oxygen.
-ECAR reflects the glycolysis activity
