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

RPM, radical pair mechanism: Click to Expand ⟱

Type:
The radical pair mechanism is a process that involves the interaction of two radicals (highly reactive molecules with unpaired electrons) and has been found to be sensitive to magnetic fields. In the presence of a magnetic field, the radical pair mechanism can be influenced, leading to changes in the reaction rates and yields.
The magnetic field effect on radical pair reactions can be explained by the following mechanisms:
Spin-correlated radical pairs: In the presence of a magnetic field, the spin-correlated radical pairs can be formed, which can lead to changes in the reaction rates and yields.

Spin relaxation: The magnetic field can influence the spin relaxation of the radicals, leading to changes in the reaction rates and yields.

Magnetic field-induced intersystem crossing: The magnetic field can induce intersystem crossing between the singlet and triplet states, leading to changes in the reaction rates and yields.

- in-vitro, Nor, NIH-3T3
Warburg↓, tNMR might have the potential to counteract the Warburg effect known from many cancer cells which are prone to glycolysis even under aerobic conditions.
Hif1a↓, combined treatment of tNMR and hypoxia (tNMR hypoxia) led to significantly altered HIF-1α protein levels, namely a further overall reduction in protein amounts
*Hif1a∅, Under normoxic conditions we did not find significant differences in Hif-1α mRNA and protein expression
Glycolysis↓, hypoxic tNMR treatment, driving cellular metabolism to a reduced glycolysis while mitochondrial respiration is kept constant even during reoxygenation.
*lactateProd↓, tNMR reduces lactate production and decreases cellular ADP levels under normoxic conditions
*ADP:ATP↓,
Pyruv↓, Intracellular pyruvate, which was as well decreased in hypoxic control cells, appeared to be further decreased after tNMR under hypoxia
ADP:ATP↓, tNMR under hypoxia further decreased the hypoxia induced decrease of the intracellular ADP/ATP ratio
*PPP↓, pentose phosphate pathway (PPP) is throttled after tNMR treatment, while cell proliferation is enhanced
*mt-ROS↑, tNMR under hypoxia increases mitochondrial and extracellular, but reduces cytosolic ROS
*ROS↓, but reduces cytosolic ROS
RPM↑, Because EMFs are known to affect ROS levels via the radical pair mechanism (RPM)
*ECAR↓, tNMR under normoxic conditions reduces the extracellular acidification rate (ECAR)

2244- MF,    Little strokes fell big oaks: The use of weak magnetic fields and reactive oxygen species to fight cancer
- Review, Var, NA
RPM↑, WEMFs affect multiple cellular processes through mechanisms such as the radical pair mechanism (RPM), which alters reactive oxygen species (ROS) levels, mitochondrial function, and glycolysis
Glycolysis∅, WEMF parallel to the magnetic field (does not enchance glycolysis)
ROS↑, WEMF can augment this effect by enhancing mitochondrial respiration, which increases ROS levels within cancer cells. This augmentation makes cancer cells more susceptible to treatment by promoting oxidative stress that can lead to apoptosis
ChemoSen↑, Chemotherapeutic agents, such as doxorubicin, primarily exert their effects by generating ROS to induce cell death. WEMF can augment this effect by enhancing mitochondrial respiration, which increases ROS levels
RadioS↑, Similarly, WEMF can enhance the efficacy of radiation therapy by increasing ROS production and sensitizing cancer cells to radiation-induced DNA damage
selectivity↑, primary advantage of WEMF is its non-invasive, non-ionizing nature, which minimizes collateral damage to healthy tissue.
