Recent progress of aptamer inhibitors targeting c-Met / 中国生化药物杂志

c-Met is one member of the receptor tyrosine kinases (RTKs).It is closely related between the over-expression of c-Met and a wide variety of tumor occurrence, development, invasion, metastasis, prognosis and drug resistance.Therefore, c-Met is a potential target for oncotherapy, and researches on its inhibitors have become a hot spot in the field of tumor treatment.Aptamers targeting c-Met are gained from systematic evolution of ligands by exponential enrichment (SELEX).They can bind to c-Met with high specificity and affinity, resulting in the activation or inhibition of c-Met.We envision that anti-c-Met aptamers would be ideal new c-Met inhibitors after optimization, and could be developed into potential targeted drugs for cancers.
