Figure 5.
Effect of hypoxia (1% O2, 24 hr) on abundance of pPP2Ac (a, b), DPP2Ac (c, d), PME‐1 (e, f), and LCMT‐1 (g, h) in HASMC and AC16 ventricular cardiomyocytes. Representative immunoblots are inset. Normalized data are presented relative to abundance at 24 hr (mean ± SEM, n = 5) under normoxic conditions and were analysed using an unpaired Student t‐test. *P < 0.05, significantly different as indicated. DPP2Ac, demethylated protein phosphatase 2A; LCMT‐1, leucine carboxyl methyltransferase‐1; PME‐1, protein phosphatase methylesterase 1; pPP2Ac, phosphorylated catalytic subunit of protein phosphatase 2A
