"Because asparaginase is so widely used to treat ALL, this new insight into how mesenchymal cells protect leukemic cells is very important," said Ching-Hon Pui, M.D., chair of the Oncology department and American Cancer Society Professor at St. Jude. "The more we learn about the molecular interactions between these cells, the more likely we'll be able to enhance the anti-leukemic action of asparaginase and perhaps other anti-leukemic drugs as well," said Pui, a co-author of the paper. "That would reduce the rate of recurrence of ALL and continue our successful efforts to increase the survival rate of ALL."
The experiments for this study were performed primarily by Shotaro Iwamoto, M.D., first author of the paper, and Keichiro Mihara, a co-author, postdoctoral fellows in Campana's laboratory.
