Author mistakes during manuscript preparation resulted in errors in the images presented in Figure 4a, ERK1/2 (panel 3), and Figure 4b. For Figure 5, beta-actin was erroneously shown as part of the analysis which it was not and this has now been removed. The corrected figures are provided below. FIGURE 4Open in figure viewerPowerPoint BA inhibits LPS-induced phosphorylation of extracellular regulated kinase (ERK) 1/2 (A) and Akt (C) but not p38 (B) in hPBMCs. hPBMCs were pretreated with BA (1–2 μg.ml−1) for 30 min. LPS (1 μg.ml−1) was then added and incubated for 30 min. Cell lysates were subjected to Western blotting with their relevant antibodies against COX-2, Akt, 3phospho-ERK and phospho-p38. Membranes were cut and probed with different antibodies. To assess non-phosphorylated forms of ERK, p38, the membranes were stripped and reprobed with specific antibodies. Photographs of chemiluminescent detection of the blots, which were representative of three independent experiments, are shown. The relative abundance of each band to its own β-actin was quantified. Data are presented as mean SEM; n = 6. #Significantly different from basal values (P < .05). *Significantly different from LPS control (P < .05). BA, betulinic acid; hPBMCs, human peripheral blood mononuclear cells; LPS, lipopolysaccharide FIGURE 5Open in figure viewerPowerPoint The quantification as shown in Figures 2 and 4 in the article remain unchanged and the authors state that these mistakes do not affect the results or conclusions of this study. The authors sincerely apologize for these mistakes. The authors would also like to update the email address of the Corresponding Author to [email protected].
