Article Title: c-Myc Quadruplex-forming Sequence Pu-27 Induces Extensive Damage in Both Telomeric and Nontelomeric Regions of DNA *
doi: 10.1074/jbc.M113.505073
Figure Lengend Snippet: Pu-27 inhibits the molecules related to DNA damage repair machinery in U937. A, RT-PCR of U937 and ΔB-U937 cells treated with Pu-27 for 3 days. Pu-27 inhibits ATM, RAD17, RAD50, CHK14, and CHK2 but not H2AX, BRCA1, and telomerase reverse transcriptase in U937 cells. B, ΔB-U937 cells showed no changes of TRF2, TRF1, POT1, TIN2, RAD17, RAD50, and 53BP1; down-regulation of ATM; up-regulation of CHK1 and CHK2; and H2AX and BRCA1.
Article Snippet: Aliquots of 0.4 ml of cells were transfected with 2 μg of the plasmid pLPC TRF2 ΔB (Addgene), which contains the TRF2 gene in which the basic domain of amino acids 1–44 is deleted.
Techniques: Reverse Transcription Polymerase Chain Reaction
