Abstract
Fragile sites were analyzed in normal peripheral lymphocytes from two acute nonlymphocytic leukemia patients with t(7;11)(p15-p13;p15) leukemic cells. To induce expression of fragile sites, cultures were exposed to folate deprivation (M-F10), BrdU, distamycin A, or Hoechst 33258. Fragility at 11p15.1 was induced by distamycin A and Hoechst 33258 but was not seen in M-F10, BrdU, and control cultures. Fra(11)(p15.1) was found neither in healthy Japanese subjects (0 in 845) nor in patients with leukemia or other hematologic disorders without the t(7;11) (0 in 126). From these results, fra(11)(p15.1) can now be classified as a rare distamycin A-inducible fragile site. Furthermore, this fra(11)(p15.1) coincided with one of the breakpoints of the t(7;11)(p15-p13;p15).Entities:
