富含GC的序列可以折叠成G-四链体和i-基序,并且已知在许多生物体中控制基因表达。有效的G-quadruplex实验抗癌药物QN-302下调了许多癌症相关基因,特别是S100 P。在这里,我们表明这种配体具有强烈的相反的影响与i-基序DNA结构,是迄今为止报道的最有效的i-基序不稳定剂之一。QN-302通过泛四链体靶向下调许多癌症相关基因的表达。与许多其他G-四链体和i-基序相互作用化合物相比,QN-302表现出特殊的组合协同效应。这项工作进一步强调了考虑G-四链体和i-基序DNA结构作为一个动态系统的重要性。有效的G-四链体实验药物QN-302与S100 P启动子处的i基序DNA结构具有强烈的相反作用。
GC-rich sequences can fold into G-quadruplexes and i-motifs and are known to control gene expression in many organisms. The potent G-quadruplex experimental anticancer drug QN-302 down-regulates a number of cancer-related genes, in particular S100P. Here we show this ligand has strong opposing effects with i-motif DNA structures and is one of the most potent i-motif destabilising agents reported to date. QN-302 down-regulates the expression of numerous cancer-related genes by pan-quadruplex targeting. QN-302 exhibits exceptional combined synergistic effects compared to many other G-quadruplex and i-motif interacting compounds. This work further emphasises the importance of considering G-quadruplex and i-motif DNA structures as one dynamic system. The potent G-quadruplex experimental drug QN-302 has strong opposing effects with i-motif DNA structures at the promoter of S100P.
