Mass spec imaging reveals elevated pathways driving tumor growth in brain cancer

Researchers from Washington University in St. Louis have developed a novel approach that allows them to study tumor growth in a new dimension. By combining mass spectrometry imaging with other techniques, they can now observe the spatial distribution and rates of nutrient usage within a tissue, providing valuable insights into the biochemical processes that drive tumor growth and potential targets for therapy. The study, published in Nature Communications, focuses on brain cancer and identifies pathways that are uniquely elevated in this type of cancer.
