  "textContent": "Researchers at Umeå University show that the protein METTL3 helps breast cancer cells spread. By regulating the release of molecules, METTL3 makes it easier for tumors to invade surrounding tissue and form metastases. The discovery reveals a previously unknown function of METTL3 and could influence future cancer treatments. The study has been published in Science Advances.",
