The research suggests that reducing production of the protein, called myoferlin, affects cancer cells in two primary ways: by changing the activation of many genes involved in metastasis in favor of normal cell behavior, and by altering mechanical properties of cancer cells — including their shape and ability to invade — so they are more likely to remain nested together rather than breaking away to travel to other tissues.
