Overexpression of miR-205-5p reverses gemcitabine resistance of MDA-MB-231/GEM cells via repression of ERp29. Compared with the miR-NC mimic + pcDNA3.1 group, protein expression level of ERp29 decreased in the miR-205-5p mimic + pcDNA3.1 group and this effect was reversed by transfection with miR-205-5p mimic + pcDNA3.1-ERp29 as demonstrated by (A) western blotting and (B) quantitative analysis. Cell apoptosis of the transfected cells was analyzed by (C) flow cytometry and (D) quantified. (E) Cell viability was measured using Cell Counting Kit-8. **P<0.01 and ***P<0.001. NC, negative control; miR, microRNA; ERp29, endoplasmic reticulum protein 29; PI, propidium iodide.
