Pang X, Zhang L, Bai F, et al. Drug Des Devel Ther. 15;9:6043–6054.The authors have advised there is an error in theWestern blot bands shown in Figure 6 on page 6050, pSmad2 at 2 weeks.Each band shown in Figure 6 represents one animal, and six or seven animals were used for each group. The statistical difference was calculated from the protein analysis using every animal tissue sample. Once the overall group statistical difference was found, three bands were chosen to represent the difference more closely between the control (Con) and curcumin (Cur) groups. The authors acknowledge the error in using the same bands in lanes two and three to show pSmad 2 at 2 weeks in the Con group. The data have been newly and independently validated from additional samples, and the results have demonstrated symmetrical expression of pSmad2 in the Con group as shown in the correct Figure 6 below.The authors apologize for this error.Read the original article
