MTTP large subunit protein in IPEC-1 cells overexpressing native swine apo A-IV (top, left) and piglike human mutant apo A-IV (top, right) incubated for 24 h with and without 0.8 mM OA and with and without 400 ng/ml DOX as assessed by Western blot analysis using β-actin to control for protein loading. Graph at bottom depicts results of densitometric analysis of the Western blots. Bars represent mean values for the MTTP large subunit/β-actin ratio ± SE from 3 Transwells as described under methods. Statistical significance is indicated by 2-tailed P values. NS, not significant.
