摘要 细胞的增殖受到细胞周期的精密调控,正调控因子可促进细胞通过调定点,负调控因子则抑制细胞通过调定点。p27kip1属于G1/S期负调控因子,可抑制细胞进入S期,而Skp2通过降解磷酸化的p27kip1从而促使细胞进入S期。Skp2在许多恶性肿瘤呈高表达,p27kip1低表达,且两者呈负相关,与肿瘤的发生及预后关系密切。干扰Skp2-p27kip1通路可作为肿瘤治疗的一条途径。但是在有些肿瘤中也检测到二者并无相关性,且与预后无关。可能还存在其他机制参与p27kip1的降解,或Skp2在肿瘤中表达增高的意义不仅局限于降解p27kip1。现主要对Skp2-p27kip1的研究进展以及二者相互关系作一综述。
