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.

UPR, Unfolded Protein Response: Click to Expand ⟱
Source:
Type:
Cellular stress response related to the endoplasmic reticulum (ER) stress, which involves protein folding, quality control, and signaling pathways. The unfolded protein response (UPR) is the cells' way of maintaining the balance of protein folding in the endoplasmic reticulum. (UPR) is triggered by the presence of misfolded proteins in the endoplasmic reticulum.
The UPR is a cellular stress response activated by the accumulation of unfolded or misfolded proteins in the endoplasmic reticulum (ER).
- It is primarily mediated by three ER-resident sensors: IRE1α, PERK, and ATF6.

Cancer cells often experience high levels of protein synthesis, hypoxia, nutrient deprivation, and oxidative stress, all of which can activate the UPR.
– Numerous studies have reported that key UPR components (e.g., GRP78/BiP, IRE1α, PERK, CHOP) are overexpressed in various malignancies such as breast, pancreatic, lung, and prostate cancers.

Unfolded Protein Response is typically upregulated in cancers and is associated with poorer prognosis due to its role in promoting cell survival, adaptation to stress, and therapeutic resistance. Although the UPR harbors the potential for tumor-suppressive (apoptotic) effects under severe stress conditions, its predominant activation in tumors supports an adaptive, protumorigenic state that facilitates cancer progression. Targeting UPR components and modulating this balance remain promising therapeutic strategies.

- in-vitro, GBM, NA
ER Stress↑, Western blot studies indicated actuated, intracellular cubic ND-PEG-SPIONs can cause mild ER stress at short periods (up to 3 h) of postmagnetic field treatment thus leading to the unfolded protein response
UPR↑,
Ca+2↑, Studies have shown that applying low-frequency magnetic fields (50 Hz) to young rats leads to stimulation of Ca2+ channel transport and therefore increases intracellular Ca2+ levels.
TRAIL↓, n the present study, we observed a similar effect where MMA caused ER stress, which resulted in a decrease in TRAIL secretion in tC17.2 stem cells
GRP78/BiP↑, A slight expression increase was also noted for the other chaperone, GRP78, for all treatment conditions.
