An international research group from Israel and Scotland has reported in <\/span>Nature Cancer <\/span><\/i>a breakthrough that may influence the treatment of metastatic leukemia spreading to the brain. The researchers include hematological-oncological experts from Schneider Children\u2019s Medical Center and Tel Aviv University, and scientists from Technion – Israel Institute of Technology and the University of Glasgow.<\/span><\/p>\n

Their research focuses on acute lymphoblastic leukemia (ALL), which is the most common type of cancer among children. Although the recovery rates for this disease are relatively high, the treatment is harsh and accompanied by numerous side effects that can persist years after the patient is cured.\u00a0<\/span><\/p>\n

Since one of the main risks of ALL is that the cancer will metastasize to the brain, children diagnosed with this disease receive a prophylactic treatment that protects the brain from metastasized cells. Currently, this treatment consists of injecting chemotherapy drugs into the spinal fluid, and sometimes also radiation to the skull, which carries the risk of side effects for damaged brain function since these chemotherapy drugs also harm healthy brain cells. For this reason, a worldwide effort is underway to develop more selective treatments that will only affect the leukemia cells and not the brain cells. The current research reveals for the first time that the solution lies in fatty acids.\u00a0<\/span><\/p>\n

Fatty acids are an essential resource for cells, including leukemia cells. Leukemia cells obtain sufficient fatty acids in the bone marrow and blood, but when they travel to the brain in a metastatic process, they reach an area that is very poor in fatty acids. According to the recently published research, in order to continue to thrive and flourish in the brain, the ALL cells develop an ability to produce fatty acids on their own.\u00a0<\/span><\/p>\n

Based on these findings, the researchers infer that treating the patient with drugs that block the production of fatty acids will prevent the leukemia cells from producing fatty acids and will thereby \u201cstarve\u201d them and stop them from flourishing in the brain. Indeed, the use of such drugs in mice has stopped the spread of metastatic leukemia to their brains.\u00a0<\/span><\/p>\n

The drugs used in the current research are still being developed and therefore not yet approved for use in humans. However, the research findings provide hope for more precise treatment that will most likely be less toxic for preventing the spread of leukemia to the brain.<\/span><\/p>\n

The article is the result of collaboration among the research groups of three scientists. The work was carried out by three young female scientists: <\/span>Dr. Angela Maria Savino<\/b> from <\/span>Professor Shai Izraeli<\/b>\u2019s lab in the Department of Hematology-Oncology at the Schneider Children\u2019s Medical Center, part of the Clalit Group, and the Department of Human Molecular Genetics and Biochemistry at Tel Aviv University\u2019s Sackler Faculty of Medicine; <\/span>Dr. Sara Isabel Fernandes<\/b> from the lab of <\/span>Professor Eyal Gottlieb<\/b> from the Rappaport Institute and Rappaport Faculty of Medicine at Technion-Israel Institute of Technology; and <\/span>Dr. Orianne Olivares<\/b> from the lab of <\/span>Professor Christina Halsey<\/b> at the Wolfson Wohl Cancer Research Centre, University of Glasgow. Part of the research was also carried out in the lab of <\/span>Professor Michael Kharas<\/b> at Memorial Sloan Kettering Cancer Center in New York.\u00a0<\/span><\/p>\n

The research findings are also relevant for several other types of cancer in children and adults in addition to acute lymphoblastic leukemia, since most mortalities from cancer are not caused by the primary tumor but, rather, by the spread of metastasized cells to distant organs. This research, which demonstrates that cancer cells adapt to the organs to which they spread, paves the way for biological treatments that block these adaptation mechanisms, thereby stopping the cancer cells from metastasizing.\u00a0<\/span><\/p>\n

The research is supported by the Chief Scientist of Israel\u2019s Ministry of Science and Technology, the Italian Foundation for Cancer Research (FIRC), the William and Elizabeth Davies Foundation, the Laura and Ike Perlmutter Fund, the German-Israeli Foundation for Scientific Research, the Norman and Sadie Lee Foundation, the Israel Science Foundation, the European Union (the ERA-NET TRASCALL program), the Israel Cancer Research Fund and Cancer Research UK. In addition, the project received funding from the European Union\u2019s Horizon\u00a02020 Research and Innovation Programme under the Marie Sk\u0142odowska-Curie grant\u00a0agreement META-CAN No 766214.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
