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)

Type:
Phosphatidylinositol 3-kinase (PtdIns3K or PI3K) is a family of enzymes that play a crucial role in cell signaling pathways, particularly in the regulation of cell growth, survival, and metabolism. The PI3K pathway is one of the most frequently altered pathways in human cancer. Inhibition of the PI3K pathway has been explored as a therapeutic strategy for cancer treatment. Several PI3K inhibitors have been developed and are currently being tested in clinical trials. These inhibitors can target specific components of the pathway, such as PI3K, AKT, or mTOR.

Class I phosphoinositide 3-kinase (PI3K)
Class III PtdIns3K
In contrast to the class III PtdIns3K as a positive regulator of autophagy, class I PI3K-AKT signaling has an opposing effect on the initiation of autophagy.

PI3K inhibitors include:
-Idelalisib , Copanlisib, Alpelisib
-LY294002?
-Wortmannin: potent PI3K inhibitor, has some associated toxicity.
-Quercetin:
-Curcumin
-Resveratrol
-Epigallocatechin Gallate (EGCG)
