title: Electrospray ionization mass spectrometry probing of formation and recognition of the G-quadruplex in the proximal promoter of the human vascular endothelial growth factor gene.
abstract: The formation of the G-quadruplex of the vascular endothelial growth factor (VEGF) gene was probed by electrospray ionization mass spectrometry (ESI-MS). It found that cations (K(+) and NH(4)(+)), CH(3)OH and pH influence significantly the formation of the G-quadruplex structure. Additionally, a perylene derivative (P3) and polydatin (P4) have shown to be potential G-quadruplex binding agents with structurally specific recognition.
