Abstract：
:We investigated whether the levels of the DNA-dependent protein kinase (DNA-PK) activity and content correlate with drug sensitivity in different tumour materials and if this can be utilised in predicting treatment outcome. DNA-PK activity and expression were investigated in tumour cells from 8 patients with chronic lymphocytic leukaemia (CLL) and 18 patients with acute myeloid leukaemia (AML), using Western blot and DNA-PK kinase activity assay. Tumour cells from the patients were investigated for their drug sensitivity to topoisomerase II inhibitors (doxorubicin and etoposide), DNA reactive agents (melphalan, 4-hydroxycyclophosphamide and cisplatinum), an antimetabolite (cytosine arabinoside) and an antimicrotubule agent (vincristine) by fluorometric microculture cytotoxicity assay (FMCA). Within each group of leukaemia there was a large variation in both DNA-PK activity and DNA-PKcs expression, while the Ku subunits were expressed more homogeneously. In CLL cells, sensitivity to topoisomerase II inhibitors correlated with DNA-PKcs protein expression (r=0.7174, p=0.0452). In AML samples, sensitivity to DNA cross-linking alkylating agents correlated with Ku86 (r=-0.7512, p=0.0031) and Ku70 (r=-0.6134, p=0.0258) expression. Unexpectedly, DNA-PK activity was found to correlate with sensitivity to vincristine in both CLL (r=0.8557, p=0.0067) and AML (r=0.5480, p=0.0228) cells. The results indicate that DNA-PK is not only involved in the recognition of DNA double-strand breaks (DSB), but also other DNA lesions.
