Correlation of chromosome patterns in human leukemic cells with exposure to chemicals and/or radiation. Final report, January 1--December 31, 1997
It has been clear for the last 15 years that cloning translocation breakpoints in both AML de novo and t-AML would provide the DNA probes required to determine whether the breakpoints in cytogenetically apparently similar translocations were identical at the level of DNA. Therefore the author has pursued an analysis of rearrangements in both types of leukemia simultaneously. She has also cloned and sequenced several translocations in acute lymphoblastic leukemia and in chronic lymphatic leukemia. Recently she cloned the breakpoint in a number of translocations involving chromosome bands 11q23 and 21q22. She has cloned the gene which she called MLL, that is located in 11q23 that is involved in the 6;11, 9;11, and 11;19 translocations that are seen in AML de novo as well as in t-AML. She has evidence that the breakpoint in 11q23 and in the t(9;11) is relatively similar in de novo and secondary AML. In addition, she has cloned the gene at the breakpoint in chromosome 21 in the t(3;21). These studies have provided DNA probes that will be very important for diagnosis and for monitoring the patient`s response to treatment.
