摘要 信号转导及转录活化因子3(signal transducer and activator of transcription 3,STAT3)是STATs家族中的重要成员,其在多种肿瘤细胞中持续激活并过度表达,与肿瘤细胞的增殖、侵袭、转移等密切相关,已成为肿瘤治疗的热点靶分子之一。目前已发现的针对STAT3的抑制剂主要有核酸类抑制剂、蛋白类抑制剂以及小分子化合物抑制剂等,其中靶向STAT3核酸类抑制剂根据其作用方式可分为小分子干扰RNA(small interfering RNA,siRNA)、反义寡核苷酸(antisense oligonucleotide,AS-ON)、诱饵寡核苷酸(decoy oligonucleotide,Decoy ON)、G-四联体寡聚脱氧核苷酸(G-quartet oligodeoxynucleotides,GQ-ODN)和显性负性质粒(dominant-negative plasmids)等5种。这些核酸类抑制剂能够在DNA或RNA水平上,通过多种方式影响STAT3活性,抑制其下游信号分子的表达,发挥抗肿瘤的活性。此类抑制剂具有作用位点明确、特异性强以及可操作性强等优点,已成为分子靶向治疗肿瘤研究中不可或缺的工具,具有潜在的临床应用价值。
