Correction: Improving the inhibitory effect of CXCR4 peptide antagonist in tumor metastasis with an acetylated PAMAM dendrimer

Abstract

Correction for ‘Improving the inhibitory effect of CXCR4 peptide antagonist in tumor metastasis with an acetylated PAMAM dendrimer’ by Changliang Liu et al., RSC Adv., 2018, 8, 39948–39956.

The authors regret that the term “CXCL12” was incorrectly displayed as “CXCR12” in Scheme 1 and Fig. 6(a)–(c) in the original article. The correct versions of Scheme 1 and Fig. 6(a)–(c) are presented below.

Scheme 1. Schematic illustration of the preparation of the P_AC80–E5 complex and the process of anti-tumor metastasis of the E5 peptide in the presence of P_AC80.

Fig. 6. (a–c) The inhibitory effect of E5 and P_AC80–E5 on: (a) MCF-7; (b) MDA-MB-231; and (c) 4T1 cells detected by transwell assay. The CXCL12 supplemented sample without E5 or P_AC80–E5 was set as 100% as the control. Error bars represent the standard deviation (n = 3).

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
