The authors agree to withdraw the Fig. 5J and replace Fig. 5 as given below. In addition, on page 8, left column, the last four lines “However, the expression of pi-p53 in RGO-treated cells was significantly increased compared to that in GO-treated cells. Furthermore, RGO-9- or RGO-12- treated cells expressed nearly 1.5 times more pi-p53 than the RGO-3- or RGO-6-treated cells (Fig. 5J). There was little statistical difference between RGOS-3 and RGO-6 or between RGO-9 and RGO-12.” should read as “However, the expression of pi-p53 in RGO-treated cells was increased compared to that in GO-treated cells”.
