肿瘤免疫——细胞增殖

细胞增殖

细胞增殖是生活细胞的重要生理功能之一,是生物体的重要生命特征,细胞以分裂的方式进行增殖。该细胞过程必须受到精准调控,即便是最小的改变也可能使该过程朝着无限增殖的方向进行,最终导致癌症的发生。为了使生物体维持动态平衡,防止出现细胞无限增殖,细胞增殖和凋亡会使生命机体维持一个动态平衡的状态。细胞增殖是是生活细胞的重要生理功能之一,是生物体的重要生命特征,细胞以分裂的方式进行增殖。该细胞过程必须受到精准调控,即便是最小的改变也可能使该过程朝着无限增殖的方向进行,最终导致癌症的发生。为了使生物体维持动态平衡,防止出现细胞无限增殖,细胞增殖和凋亡会使生命机体维持一个动态平衡的状态。

在真核细胞中,细胞周期可以分为三个主要阶段:

1. 分裂间期(Interphase):由G1期(DNA合成前期),S期(DNA合成期),G2期(DNA合成后期)组成,主要是DNA的复制过程。

2. 分裂期(Mitotic Phase):简称M期,由4个阶段组成(前期、中期、后期和末期)

3. 保质分裂(Cytokinesis):将细胞膜、细胞骨架、细胞器,以及可溶性的蛋白质等均分,形成两个新的子细胞

细胞增殖的标记物

A) MCM (微小染色体维持蛋白)。 MCM只存在于真核细胞中。 MCM在有丝分裂的晚期和G1期与染色质紧密结合,在S期和G2期分开。MCM蛋白只在细胞的增殖期才能检测到,它的表达在G1/S 转换点达到峰值,在分化期和静息期时,表达缺失,因此可以作为细胞增殖的特殊标志物。 B) 细胞核相关抗原Ki-67。 这个分子是经典的细胞增殖相关分子标志物,最早在1983年在增殖细胞中发现,目前在病理诊断中使用非常地广泛。 Ki-67的一级结构比较特殊,还没有发现与之同源的蛋白,所以目前对于 Ki-67 的功能了解得不多。 推测它可能具有如下的几个功能:1).推测 Ki-67 可以调节细胞周期; 2).Ki-67 能和 DNA 或者 RNA 发 生相互结合; 3).Ki-67 在细胞分裂期参与合成核糖体。 Ki-67 在细胞的G0期不表达,G1中期到后期出现表达,S期和G2期表达逐渐增加,有丝分裂期达到高峰,细胞分裂后迅速降解。

B) 细胞核相关抗原Ki-67。这个分子是经典的细胞增殖相关分子标志物,最早在1983年在增殖细胞中发现,目前在病理诊断中使用非常地广泛。 Ki-67的一级结构比较特殊,还没有发现与之同源的蛋白,所以目前对于 Ki-67 的功能了解得不多。推测它可能具有如下的几个功能:1).推测 Ki-67 可以调节细胞周期; 2).Ki-67 能和 DNA 或者 RNA 发 生相互结合; 3).Ki-67 在细胞分裂期参与合成核糖体。 Ki-67 在细胞的G0期不表达,G1中期到后期出现表达,S期和G2期表达逐渐增加,有丝分裂期达到高峰,细胞分裂后迅速降解。

C) 增殖细胞核抗原 PCNA。 PCNA 又称为周期素,它是DNA聚合酶δ的辅助蛋白。这个分子也是经典的增殖相关分子标志物,最早在 1978 年就有所报道。又因为PCNA出现在增殖期细胞的细胞核中,所以被称之为增殖细胞核抗原。PCNA的主要功能有:1).DNA 聚合酶δ的辅助蛋白; 2).参与 DNA 损伤的修复; 3).参与细胞周期的调控; 4).和 p21 相互作用。p21 是 CDK 的抑制因子,因此PCNA通过和p21相互作用,间接影响细胞周期和增殖。在增殖细胞的细胞周期中,PCNA的量会发生明显变化,它在G0/G1期几乎没有表达,G1晚期表达大幅度增加,S期达到高峰,G2/M 期表达下降。 PCNA 也已经广泛应用于临床病理诊断和相关的生物学研究中。
