Although chemotherapy can fight back cancer, it also has been associated with increased risk of leukemia years after the treatment. What leads to that association is not clear, but a recent report has provided some answers. The answers involve a gene calledPPM1D, whose function in blood production was unknown. Furthermore, the implications of these findings can affect the choice of chemotherapies. The journey that led to these findings began on the bedside and then moved into the research lab, highlighting the importance of collaboration between clinical and basic science researchers. Baylor M.D./Ph.D. student, Joanne Ino Hsu participated in this research.
