Abstract:
We report a case of acute myeloid leukemia (AML) subtype M2, with t(5;11)(q35;q13), in a 30-year-old man. Conventional cytogenetic, spectral karyotyping, and fluorescence in situ hybridization (FISH) studies on bone marrow sample obtained at diagnosis revealed an abnormal karyotype in all cells examined. FISH analysis demonstrated absence of translocations in the region of the cyclin D1 gene and real-time quantitative reverse transcriptase-polymerase chain reaction revealed normal expression of this gene. Similar to the 11q23 region, 11q13 changes can be found in both myeloid and lymphoid neoplasias with different chromosomes serving as donors in translocations.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
