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.


PI3K, Phosphatidylinositide-3-Kinases: Click to Expand ⟱
Source: HalifaxProj(inhibit) CGL-CS
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)

JNK↑,
p38↑,
eff↓, ontrarily, when cells are exposed to ELF‐EMF, a new source of ROS production is introduced in cells which can at least partially reverse anticancer effects observed with cell's treatment with melatonin.
*toxicity?, More importantly, ELF‐EMF exposure to normal cells in most cases has shown to be safe and un‐harmful.
