摘要

Four putative G-quadruplex sequences (PGSs) in the HIF1α promoter and the 5′ UTR were evaluated for their G-quadruplex-forming potential using ESI-MS, CD, FRET, DMS footprinting, and a polymerase stop assay. An important G-quadruplex (S1) has been proven to inhibit HIF1α transcription by blocking AP2 binding. A benzo [c] phenanthridine derivative was found to target the S1 G-quadruplex and induce its conformational conversion from ...
