Figure 3. LDL increases ERK 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 ERK phosphorylation (P-ERK and T-ERK means phosphorylated and total ERK). B: This panel shows representative western immunoblots from one experiment, and densitometric data from three experiments (mean±SD) describing dose effects of LDL on ERK phosphorylation. N-LDL and HOG-LDL had similar effects on ERK1/2 phosphorylation. Control immunosignal (T-ERK) bands were detected in the same gels as P-ERK after stripping and re-probing. In both panels, densitometric calculations of P-ERK were corrected for T-ERK. Asterisk represents p<0.05 compared to control (Time 0 or Dose 0).
