Effects of catalpol on the activation of the extracellular signal-regulated kinase 1/2 (ERK1/2) pathway in PreOLs under OGD and KB-R7943 treatment. (A) Western blot probing for p-ERK1/2 and poly-ADP-ribose polymerase-1 (PARP-1) from the CTL, OGD, CAT, and KB+CAT groups. Total ERK1/2 and β-actin were used as loading controls. The blot shown is representative of six independent experiments. (B) Quantification of p-ERK1/2 and PARP-1 protein expression levels from Western blot analyses. Data are shown as means ± SEM (n = 6 in each group). * p < 0.05; ** p < 0.01.
