Figure 6From: Intermittent hypoxia-induced protein phosphatase 2A activation reduces PC12 cell proliferation and differentiation Possible molecular mechanisms for intermittent hypoxia (IH)-induced activation of protein phosphatase 2A (PP2A) and inhibition of extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation contribute to inhibiting PC12 cell proliferation through G 0 /G 1 phase arrest and nerve growth factor (NGF)-induced neuronal differentiation.
