Multiple myeloma (MM) is a type of blood cancer that affects plasma cells, which are responsible for producing antibodies. MM is characterized by the accumulation of abnormal plasma cells in the bone marrow, leading to bone damage, kidney failure, anemia, and increased susceptibility to infections. MM is a heterogeneous disease with different subtypes and genetic mutations that affect the prognosis and response to treatment. Therefore, there is a need for new biomarkers and therapeutic targets that can improve the outcomes of MM patients. One of the potential targets that has recently emerged is the fatty acid binding protein (FABP) family. FABPs are proteins that bind and transport fatty acids, which are essential for energy production, cell signaling and membrane synthesis. FABPs are expressed in various tissues and organs, and have different roles depending on their location and type. There are nine members of the FABP family, but FABP5 seems to be the most relevant for MM. In a recent editorial paper, researchers Heather Fairfield and Michaela R. Reagan from Maine Health Institute for Research, University of Maine and Tufts University School of Medicine summarized previous findings from their 2023 study and the current evidence on the role of FABPs in MM. On June 19, 2023, their editorial was published in Oncotarget, entitled, “The hope for targeting fatty acid binding proteins in multiple myeloma.” Full blog - https://www.oncotarget.org/2023/09/21/targeting-fatty-acid-binding-proteins-in-multiple-myeloma/ Paper DOI - https://doi.org/10.18632/oncotarget.28437 Correspondence to - Michaela R.
