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

- most reports have ROS production increasing in cancer cells , while decreasing in normal cells.

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:

Hypoxia-inducible factor 1 (HIF-1) is a transcription factor that plays a crucial role in cellular responses to low oxygen levels (hypoxia). It is composed of two subunits: HIF-1α and HIF-1β. Under normal oxygen conditions, HIF-1α is rapidly degraded, but in hypoxic conditions, it stabilizes, translocates to the nucleus, and dimerizes with HIF-1β to activate the transcription of various genes involved in processes such as angiogenesis, metabolism, and cell survival.
HIF-1α is often overexpressed due to the hypoxic microenvironment created by rapid tumor growth and inadequate blood supply. This upregulation allows cancer cells to adapt to low oxygen levels. HIF-1 regulates the expression of numerous target genes involved in angiogenesis (e.g., VEGF), glucose metabolism (e.g., GLUT1), cell survival, and invasion. The activation of these genes promotes tumor growth and metastasis.
However, HIF-1 is expressed in pathological conditions such as cancer and obesity.
