Features: Therapy
Magnetic Fields can be Static, or pulsed. The most common therapy is a pulsed magnetic field in the uT or mT range.
The main pathways affected are:
Calcium Signaling: -influence the activity of voltage-gated calcium channels.
Oxidative Stress and Reactive Oxygen Species (ROS) Pathways
Heat Shock Proteins (HSPs) and Cellular Stress Responses
Cell Proliferation and Growth Signaling: MAPK/ERK pathway.
Gene Expression and Epigenetic Modifications: NF-κB
Angiogenesis Pathways: VEGF (improving VEGF for normal cells)
PEMF was found to have a 2-fold increase in drug uptake compared to traditional electrochemotherapy in rat melanoma models

Non-Static Magnetic Fields (AC / Pulsed / Oscillating MF)
Rank Pathway / Axis Cancer Cells Normal Cells TSF Primary Effect Notes / Interpretation
1 Reactive oxygen species (ROS) ↑ ROS (P→R); often sustained (G) ↑ ROS (P); ↔/↓ net ROS (R→G) P, R, G Upstream redox perturbation MF perturbs electron/radical dynamics: normal cells often adapt (ROS setpoint ↓), cancer cells less so
2 NRF2 antioxidant response ↔ / insufficient NRF2 induction (R→G) ↑ NRF2 activation (R→G) R, G Adaptive redox defense Explains mixed ROS direction in normal cells (initial ↑ then adaptive ↓)
3 Glutathione (GSH) homeostasis ↓ GSH (R→G) ↔ or transient ↓ (R) with recovery (G) R, G Redox buffering capacity GSH depletion reflects sustained oxidative load; recovery indicates successful adaptation
4 Superoxide dismutase (SOD) / antioxidant enzymes ↔ or inadequate enzyme upshift (G) ↑ SOD/GPx/CAT capacity (G) G Longer-term antioxidant remodeling Often the “endpoint” readout that correlates with ROS-normalization in normal tissue
5 Mitochondrial ETC / respiration ↓ ETC efficiency; ↑ electron leak (P→R) ↔ mild, reversible ETC perturbation (P→R) P, R Bioenergetic destabilization ETC perturbation is a mechanistic bridge between MF exposure and ROS/ΔΨm changes
6 Mitochondrial membrane potential (ΔΨm / MMP) ↓ ΔΨm (R); may progress (G) ↔ preserved or reversible dip (R) R, G Mitochondrial dysfunction thresholding ΔΨm loss typically follows ROS/ETC disruption rather than preceding it
7 Ca²⁺ signaling (VGCC / ER–mitochondria Ca²⁺ flux) ↑ dysregulated Ca²⁺ influx/transfer (P→R); overload may persist (G) ↑ transient Ca²⁺ signaling (P); homeostasis restored (R→G) P, R, G Stress signal amplification Ca²⁺ dysregulation links ROS/ETC perturbation to ER stress and mitochondrial dysfunction (amplifies ΔΨm loss and UPR commitment)
8 Mitochondrial permeability transition pore (MPTP) ↑ MPTP opening propensity (R); sustained opening possible (G) ↔ transient or closed (R→G) P, R, G Commitment point for mitochondrial failure MPTP opening integrates ROS, Ca²⁺ overload, and ΔΨm loss; acts as a threshold event converting reversible stress into irreversible mitochondrial dysfunction
9 ER stress / UPR ↑ ER stress (R); CHOP-commitment possible (G) ↑ adaptive UPR (R); resolves (G) R, G Proteostasis stress Often downstream of ROS + Ca²⁺ handling perturbations
10 DNA damage (oxidative) ↑ damage markers (R→G) ↔ or repaired (G) R, G Checkpoint pressure Generally secondary to ROS; interpret as stress consequence not “direct genotoxicity”
11 LDH / glycolytic flux ↓ glycolytic performance (R→G) ↔ flexible substrate switching (R→G) R, G Metabolic vulnerability Redox imbalance can destabilize high-rate glycolysis in cancer-biased contexts
12 Thioredoxin system (Trx / TrxR) ↓ functional reserve / overload (R→G) ↔ preserved capacity (G) R, G Parallel antioxidant system stress Useful when GSH-only does not explain redox phenotype 
Time-Scale Flag: TSF = P / R / G
  P: 0–30 min (physical / electron / radical effects)
  R: 30 min–3 hr (redox signaling & stress response)
  G: >3 hr (gene-regulatory adaptation)
MPTP: opening represents a mitochondrial commitment event integrating ROS and Ca²⁺ stress; sustained opening indicates irreversible bioenergetic failure.

Type:
Endonucleases are enzymes that play a crucial role in the maintenance of genome stability by cleaving the phosphodiester backbone of DNA. In the context of cancer, endonucleases can have both tumor-suppressing and tumor-promoting effects.

1. APEX1 (Apurinic/Apyrimidinic Endonuclease 1)
Cancers: Breast cancer, lung cancer, colorectal cancer Prognosis: High expression is often associated with poor prognosis due to its role in DNA repair and resistance to chemotherapy.
2. FEN1 (Flap Endonuclease 1)
Cancers: Breast cancer, prostate cancer, pancreatic cancer
Prognosis: Overexpression is linked to increased tumor aggressiveness and poor survival rates.
3. EXO1 (Exonuclease 1)
Cancers: Colorectal cancer, ovarian cancer
Prognosis: High levels of EXO1 expression can correlate with poor prognosis and increased risk of metastasis.
4. DNase I (Deoxyribonuclease I)
Cancers: Various solid tumors
Prognosis: Altered expression levels can be indicative of tumor progression and immune evasion. 5. Caspase-3 (an endonuclease involved in apoptosis)
Cancers: Various cancers, including leukemia and solid tumors
Prognosis: High levels of active caspase-3 are often associated with increased apoptosis and may correlate with better treatment responses.
6. Rad51 (a recombinase with endonuclease activity)
Cancers: Breast cancer, ovarian cancer
Prognosis: Elevated expression is often linked to resistance to DNA-damaging therapies and poor prognosis.
7. MRE11 (part of the MRN complex)
Cancers: Breast cancer, lung cancer
Prognosis: Altered expression can indicate defects in DNA repair mechanisms, influencing treatment outcomes.
8. TDP1 (Tyrosyl-DNA Phosphodiesterase 1)
Cancers: Glioblastoma, breast cancer
Prognosis: High expression levels may be associated with resistance to certain chemotherapeutic agents.
9. UNG (Uracil-DNA Glycosylase)
Cancers: Colorectal cancer, lung cancer
Prognosis: Its expression can influence the mutation rate and may correlate with tumor aggressiveness.
10. LIG3 (DNA Ligase III)
Cancers: Various cancers, including breast and prostate cancer
Prognosis: Overexpression may be linked to enhanced DNA repair capabilities, contributing to treatment resistance.
