Correction to: Exosomes from tamoxifen-resistant breast cancer cells transmit drug resistance partly by delivering miR-9-5p

The Original Article was published on 15 January 2021

Correction to: Cancer Cell Int (2021) 21:55 https://doi.org/10.1186/s12935-020-01659-0

Following the publication of the original article [1], we were notified of an error in Fig. 4.

The corrected Fig. 4 can be found in this erratum.

Fig. 4
figure 1

miR-9-5p targets and negatively regulates ADIPOQ. a The prediction of binding sites between miR-9-5p and ADIPOQ. b Quantitation of the luciferase activity assay. c The expression pattern of miR-9-5p in each group measured by RT-qPCR. d The mRNA expression pattern of ADIPOQ in the cells of each group measured by RT-qPCR. e The protein expression pattern of ADIPOQ in cells of each group evaluated by Western blot analysis. *p < 0.05. Each experiment was conducted three times independently

Errors have subsequently been identified in the original publication, and the following correction should be noted:

While analyzing the results of “nanoparticles in the concentration and size of exosomes” in the research, the result analysis of the original Fig. 1b is inaccurate. The corrected Fig. 1 is given below.

Fig. 1
figure 2

Exosomes from MCF-7/TAM cells can be transferred into the parental MCF-7 cells. a TEM observation of exosomes (scale bar: 200 nm). b Nanoparticle tracking analysis of exosome concentration and size. c The expression patterns of marker proteins (CD63 and TSG101) of exosomes in MCF-7-exo and MCF-7/TAM-exo detected by Western blot analysis (normalized to β-actin). d MCF-7-exo and MCF-7/TAM-exo (labeled with PKH67 dye) could be internationalized by parental MCF-7 cells (scale bar: 25 μm)
