丝氨酸/苏氨酸磷酸酶2C型(PPM 1A)具有广泛的底物范围,并且其在调节应激反应中的作用已被充分确立。我们研究了PPM 1A在PC6-3细胞(PC 12细胞系的亚克隆)的存活和分化过程中的参与。该细胞系在暴露于神经生长因子(NGF)后可分化成神经元样细胞。PPM 1A在幼稚PC 6 -3细胞中的过表达导致细胞周期停滞在G2/M期,随后发生凋亡。有趣的是,PPM 1A过表达并不影响完全分化的细胞。使用PPM 1A过表达细胞和PPM 1A敲低细胞,我们发现这种磷酸酶影响PC6-3细胞中的NGF信号传导,并参与神经突生长。此外,在PC6-3细胞分化过程中,PPM 1A的消融干扰了NGF诱导的生长停滞。
The serine/threonine phosphatase type 2C (PPM1A) has a broad range of substrates, and its role in regulating stress response is well established. We have investigated the involvement of PPM1A in the survival and differentiation processes of PC6-3 cells, a subclone of the PC12 cell line. This cell line can differentiate into neuron like cells upon exposure to nerve growth factor (NGF). Overexpression of PPM1A in naive PC6-3 cells caused cell cycle arrest at the G2/M phase followed by apoptosis. Interestingly, PPM1A overexpression did not affect fully differentiated cells. Using PPM1A overexpressing cells and PPM1A knockdown cells, we show that this phosphatase affects NGF signaling in PC6-3 cells and is engaged in neurite outgrowth. In addition, the ablation of PPM1A interferes with NGF-induced growth arrest during differentiation of PC6-3 cells.
