Relative ethanolamine plasmalogens in DHAPAT-deficient cells (A). Plasmalogen content of CHO (C_V) and NRel-4 (N_V) cell lines. Values are an average of three independent experiments; error bars represent standard deviation. All transitions measured in NRel-4 cells were significantly different from control cells (p < 0.05). Cholesterol profile of DHAPAT-deficient cells (B). Values are an average of independent experiments; error bars represent standard deviation. Total, free and esterified cholesterol of N_V is significantly different from C_V ( p < 0.05).
