Figure 5. LDL increases p38MAPK phosphorylation. A: This panel shows representative western immunoblots from one experiment, and densitometric data from three experiments (mean±SD) describing the time course of LDL-induced p38 MAPK phosphorylation (P-p38MAPK and T-p38MAPK means phosphorylated and total p38 MAPK). B: This panel shows representative western immunoblots from one experiment, and densitometric data from three experiments (mean±SD) describing dose effects of LDL on p38 MAPK phosphorylation. N-LDL and HOG-LDL had similar effects on p38 MAPK phosphorylation. Control immunosignal (T-p38MAPK) bands were detected in the same gels as P-p38MAPK after stripping and re-probing. In both panels, densitometric calculations of P-p38MAPK were corrected for T-p38MAPK. Asterisk represents p<0.05 compared to control (Time 0 or Dose 0).
