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)

TP53 is the most commonly mutated gene in human cancer. TP53 is a gene that encodes for the p53 tumor suppressor protein ; TP73 (Chr.1p36.33) and TP63 (Chr.3q28) genes that encode transcription factors p73 and p63, respectively, are TP53 homologous structures.
p53 is a crucial tumor suppressor protein that plays a significant role in regulating the cell cycle, maintaining genomic stability, and preventing tumor formation. It is often referred to as the "guardian of the genome" due to its role in protecting cells from DNA damage and stress.
TP53 gene, which encodes the p53 protein, is one of the most frequently mutated genes in human cancers.
Overexpression of MDM2, an inhibitor of p53, can lead to decreased p53 activity even in the presence of wild-type p53.
In some cancers, particularly those with mutant p53, there may be an overexpression of the p53 protein.
Cancers with overexpression: Breast, lung, colorectal, overian, head and neck, Esophageal, bladder, pancreatic, and liver.
