| 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 Pathways: - most reports have ROS production increasing in cancer cells , while decreasing in normal cells. - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, UPR↑, GRP78↑, Ca+2↑, Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑, HSP↓, Prx, - Raises AntiOxidant defense in Normal Cells: ROS↓, NRF2↑, SOD↑, GSH↑, Catalase↑, - lowers Inflammation : NF-kB↓, COX2↓, Pro-Inflammatory Cytokines : NLRP3↓, IL-1β↓, TNF-α↓, IL-6↓, IL-8↓ - inhibit Growth/Metastases : TumMeta↓, TumCG↓, VEGF↓(mostly regulated up in normal cells), - cause Cell cycle arrest : TumCCA↑, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, TNF-α↓, - inhibits glycolysis /Warburg Effect and ATP depletion : HIF-1α↓, PKM2↓, GLUT1↓, LDH↓, HK2↓, PFKs↓, PDKs↓, ECAR↓, OXPHOS↓, GRP78↑, Glucose↓, GlucoseCon↓ - inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, Notch↓, FGF↓, PDGF↓, EGFR↓, Integrins↓, - Others: PI3K↓, AKT↓, STAT↓, Wnt↓, β-catenin↓, ERK↓, JNK, - SREBP (related to cholesterol). - Synergies: chemo-sensitization, chemoProtective, cytoProtective, RadioSensitizer, RadioProtective, Others(review target notes), Neuroprotective, Hepatoprotective, CardioProtective, - Selectivity: Cancer Cells vs Normal Cells Non-Static Magnetic Fields (AC / Pulsed / Oscillating MF)
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. |

| Mitogen-activated protein kinases (MAPKs) are a group of proteins involved in transmitting signals from the cell surface to the nucleus, playing a crucial role in various cellular processes, including growth, differentiation, and apoptosis (programmed cell death). MAPK Pathways: The MAPK family includes several pathways, the most notable being: 1.ERK (Extracellular signal-Regulated Kinase): Often associated with cell proliferation and survival. 2.JNK (c-Jun N-terminal Kinase): Typically involved in stress responses and apoptosis. 3.p38 MAPK: Associated with inflammatory responses and apoptosis. Inhibitors: Targeting the MAPK pathway has become a strategy in cancer therapy. For example, BRAF inhibitors (like vemurafenib) are used in treating melanoma with BRAF mutations. Altered Expression Levels: Overexpression: Many cancers exhibit overexpression of MAPK pathway components, such as RAS, BRAF, and MEK. This overexpression can lead to increased signaling activity, promoting cell proliferation and survival. Downregulation: In some cases, negative regulators of the MAPK pathway (e.g., MAPK phosphatases) may be downregulated, leading to enhanced MAPK signaling. The expression levels of MAPK pathway components can serve as biomarkers for cancer diagnosis, prognosis, and treatment response. For example, high levels of phosphorylated ERK (p-ERK) may indicate active MAPK signaling and poor prognosis in certain cancers. Numerous reports indicate that the MAPK pathway plays a major role in tumor progression and invasion, while inhibition of MAPK signaling reduces invasion. |
