- Selectivity: Cancer Cells vs 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.


TumCI, Tumor Cell invasion: Click to Expand ⟱
Source:
Type:
Tumor cell invasion is a critical process in cancer progression and metastasis, where cancer cells spread from the primary tumor to surrounding tissues and distant organs. This process involves several key steps and mechanisms:

1.Epithelial-Mesenchymal Transition (EMT): Many tumors originate from epithelial cells, which are typically organized in layers. During EMT, these cells lose their epithelial characteristics (such as cell-cell adhesion) and gain mesenchymal traits (such as increased motility). This transition is crucial for invasion.

2.Degradation of Extracellular Matrix (ECM): Tumor cells secrete enzymes, such as matrix metalloproteinases (MMPs), that degrade the ECM, allowing cancer cells to invade surrounding tissues. This degradation facilitates the movement of cancer cells through the tissue.

3.Cell Migration: Once the ECM is degraded, cancer cells can migrate. They often use various mechanisms, including amoeboid movement and mesenchymal migration, to move through the tissue. This migration is influenced by various signaling pathways and the tumor microenvironment.

4.Angiogenesis: As tumors grow, they require a blood supply to provide nutrients and oxygen. Tumor cells can stimulate the formation of new blood vessels (angiogenesis) through the release of growth factors like vascular endothelial growth factor (VEGF). This not only supports tumor growth but also provides a route for cancer cells to enter the bloodstream.

5.Invasion into Blood Vessels (Intravasation): Cancer cells can invade nearby blood vessels, allowing them to enter the circulatory system. This step is crucial for metastasis, as it enables cancer cells to travel to distant sites in the body.

6.Survival in Circulation: Once in the bloodstream, cancer cells must survive the immune response and the shear stress of blood flow. They can form clusters with platelets or other cells to evade detection.

7.Extravasation and Colonization: After traveling through the bloodstream, cancer cells can exit the circulation (extravasation) and invade new tissues. They may then establish secondary tumors (metastases) in distant organs.

8.Tumor Microenvironment: The surrounding microenvironment plays a significant role in tumor invasion. Factors such as immune cells, fibroblasts, and signaling molecules can either promote or inhibit invasion and metastasis.
