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.
OCR, Oxygen consumption rate: Click to Expand ⟱

Type:
Oxygen consumption rate (OCR) is a measure of the rate at which cells consume oxygen, and it has been found to be altered in cancer cells. Cancer cells often exhibit increased glycolysis, a process in which glucose is converted into energy without the use of oxygen, even in the presence of oxygen. This is known as the Warburg effect.
Cancer cells often exhibit increased glycolysis, which leads to a decrease in OCR.
-When mitochondrial function is impaired (resulting in lower OCR), cells may compensate by upregulating glycolysis to meet their energy needs (known as the Pasteur effect).
-Instruments such as the Seahorse Analyzer allow simultaneous measurement of OCR (reflecting mitochondrial respiration) and Extracellular Acidification Rate (ECAR, which is commonly used as a proxy for glycolysis). This dual measurement helps researchers understand how shifts in one pathway correlate with compensatory changes in the other.
