1 Here, we report that the DNA-dependent protein kinase (DNA-PK) and p53 are able to form a protein complex that interacts with the gemcitabine-containing DNA and plays a role in signaling to apoptotic pathways. gemcitabine tumor protein p53 Homo sapiens
2 DNA-PK/Ku and p53 were copurified in a protein fraction that binds to gemcitabine-containing DNA in preference to normal DNA. gemcitabine tumor protein p53 Homo sapiens
3 Treatment with gemcitabine resulted in an increase of DNA-PK and p53 protein and an increase in the phosphorylation of p53 at Ser15. gemcitabine tumor protein p53 Homo sapiens
4 Treatment with gemcitabine resulted in an increase of DNA-PK and p53 protein and an increase in the phosphorylation of p53 at Ser15. gemcitabine tumor protein p53 Homo sapiens
5 Furthermore, confocal microscopy demonstrated a colocalization of DNA-PK and p53 to the nucleus in cells treated with gemcitabine. gemcitabine tumor protein p53 Homo sapiens
6 Although the wild-type p53 present in the protein complex exhibited 3"-5" exonuclease activity, it was incapable of excising the incorporated gemcitabine from DNA. gemcitabine tumor protein p53 Homo sapiens
