Modified oligonucleotides having a conserved G
4
sequence and a sufficient number of flanking nucleotides to significantly inhibit the activity of a virus or phospholipase A
2
or to modulate the telomere length of a chromosome are provided. G
4
quartet oligonucleotide structures are also provided. Methods of prophylaxis, diagnostics and therapeutics for viral-associated diseases and diseases associated with elevated levels of phospholipase A
2
are also provided. Methods of modulating telomere length of a chromosome are also provided; modulation of telomere length is believed to play a role in the aging process of a cell and in control of malignant cell growth.
提供具有保守的G4序列和足够数量的侧翼核苷酸的修饰寡核苷酸,可以显著抑制病毒或
磷脂酶A2的活性或调节染色体端粒长度。还提供了G4四链体寡核苷酸结构。还提供了预防病毒相关疾病和与
磷脂酶A2
水平升高相关的疾病的诊断和治疗方法。还提供了调节染色体端粒长度的方法;调节染色体端粒长度被认为在细胞老化过程和恶性细胞生长的控制中起作用。
