Exosome-Mediated Transfer of miR-3613-5p Enhances Doxorubicin Resistance by Suppression of PTEN Expression in Breast Cancer Cells

Figure 1

miR-3613-5p is upregulated in drug-resistant tissue and breast cancer cells. (a) The expression level of miR-3613-5p in GEO chip (GSE73736) of drug-sensitive tissue and drug-resistant tissue. , . (b) Cell viability of doxorubicin nonresistant and resistant breast cancer cell lines (MCF-7 and MDA-MB-231, MCF-7/DOX, and MDA-MB-231/DOX, respectively) after different doses of doxorubicin treatments was assessed with CCK8. (c) qRT-PCR was performed to assess the relative levels of miR-3613-5p in MCF-7, MCF-7/DOX, MDA-MB-231, and MDA-MB-231/DOX. . Data are of 3 independent experiments.
