1 After 3-4 days of IH, extracellular signal-regulated kinases 1/2 (ERK1/2) protein phosphorylation decreased, which could be reversed by superoxide dismutase (SOD), 1,10-phenanthroline (Phe), the PP2A phosphorylation inhibitors, okadaic acid (OKA) and cantharidin, and the ERK phosphorylation activator nicotine (p < 0.05). 1,10-phenanthroline Eph receptor B1 Rattus norvegicus

3 In particular, the significantly reduced cell proliferation and increased proportions of cells in the G0/G1 phase after 1-4 days of IH (p < 0.05), which resulted in decreased numbers of PC12 cells, could be reversed by treatment with SOD, Phe, PP2A inhibitors and an ERK activator. 1,10-phenanthroline Eph receptor B1 Rattus norvegicus
