Title: Lithium
Post by: danialthomas on October 11, 2021, 03:51:44 pm
To help induce iron-mediated death of cancer cells (ferroptosis), besides blocking the ferroptosis-inhibiting carbonic anhydrase #9 (CAIX) protein, it is important to target the lymphatic system. Cancer cells often metastasize regionally through the lymphatic system before they metastasize systemically through the bloodstream. Exposure to lymph fluid has been found to protect cancer cells from ferroptosis and increase their ability to survive during subsequent metastasis through the blood. Differences between lymph fluid and blood plasma that may contribute to this include higher levels of glutathione and oleic acid and less iron in lymph fluid.

To help suppress the metastatic potential of cancer cells via the lymphatic system and promote ferroptosis, lithium has been found to:

a) decrease lymphatic density and surface contact with cancer cells
b) inhibit the migration of cancer cells to the lymphatic system
c) decrease lymphatic permeability, thereby inhibiting cancer cells from entering or exiting the lymphatic system.
