XRCC6 and acute myeloid leukemia: To exclude the classical NHEJ pathway in generatingchromosomal translocations, we quantified the expressionlevel of KU70 and observed no evidence for significantdysregulation of this gene in AML patients based on absenceor presence of chromosomal translocations, suggesting thatformation of chromosomal translocation in AML patients isless likely to be exerted through the cNHEJ pathway.
