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

GRP78/BiP, HSPA5: Click to Expand ⟱

Type:
GRP78 (Pgp, BiP or ERp72) is a central regulator of endoplasmic reticulum (ER) function due to its roles in protein folding and assembly, targeting misfolded protein for degradation, ER Ca(2+)-binding and controlling the activation of trans-membrane ER stress sensors.
-GRP78 protein, a marker for endoplasmic reticulum stress
-GRP78’s role as a master regulator of the unfolded protein response (UPR) and cellular stress responses
The association of P-gp and inhibition of cell death in cancerous cells has also been reported in several studies including in hepatocellular, colorectal, prostate cancer, and gastric cancer. Although counterintuitive due to its prominent role in cancer resistance, P-gp has been linked to favorable prognosis.
ERp72 can promote cancer cell proliferation, migration, and invasion by regulating various signaling pathways, including the PI3K/AKT and MAPK/ERK pathways. Additionally, ERp72 can also inhibit apoptosis (programmed cell death) in cancer cells, which can contribute to tumor progression. Overexpressed in: Breast, lung colorectal, prostrate, ovarian, pancreatic.

-GRP78 is frequently upregulated in a variety of solid tumors and hematological malignancies.
-Overexpression of GRP78 in cancer cells is often regarded as a marker of increased ER stress due to the reduced oxygen and nutrient supply typically encountered in the tumor microenvironment.
-Elevated GRP78 levels can contribute to tumor cell survival by enhancing the adaptive UPR, allowing cancer cells to cope with therapeutic and metabolic stress.

3459- MF,    EFFECT OF PULSED ELECTROMAGNETIC FIELDS ON ENDOPLASMIC RETICULUM STRESS
- in-vitro, Cerv, HeLa
GRP78/BiP↑, the expression of BiP, Grp94 and CHOP were increased in HeLa cells upon PEMF exposure.
GRP94↑,
CHOP↑,
ER Stress↓, Our main findings are that PEMF exposure (8 Hz and meant flux density of 0.56 mT) is able to reduce the elevated activity of ER stress markers induced by tunicamycin, in HepG2 cell line.

3458- MF,    Magnetic Control of Protein Expression via Magneto-mechanical Actuation of ND-PEGylated Iron Oxide Nanocubes for Cell Therapy
- 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.
