DNA POLYMERASE STOP ASSAY FOR DETECTION OF G-QUADRUPLEXES
Petr, Marek ; Bažantová, Pavla ; Adámik, Matěj ; Kejnovská, Iva ; Dvořáková, Zuzana ; Vorlíčková, Michaela ; Pečinka, Petr ; Brázdová, Marie
In this work we performed DNA polymerase stop assays while using template DNA derived from promoter regions of VEGF and c-Myc proto-oncogenes under variety of experimental conditions. Partial stopping of DNA synthesis along the template strand was observed in the presence of K+ ions due to formation of stable G-quadruplex structures. In contrast, Na+ ions alone were unable to stabilize G-quadruplexes to stop the reaction at their site. These data suggest that K+ and Na+ ions, which are both known to stabilize G-quadruplexes, do this in different manner or extent.
ANALYSIS OF SEQUENCE SPECIFIC INTERACTIONS BETWEEN DNA AND P53 FAMILY PROTEINS BY ELISA, SLOT-BLOT AND EMSA

DNA-protein interactions of core domains of p53, p63 and p73, members of tumor suppressor p53 family, were investigated by multiple methods with regard to verifying the sequence specificity with which short target oligonucleotides/long DNA fragments can be recognized. The sequence specificity of core domains and wtp53 full protein binding to specific sequence in both types of DNA substrates was confirmed in solution, on surface and in gels by ELISA, slot-blot and EMSA.
