Altered expression of miR-620 and DCTD contributes to gemcitabine resistance in patients with TNBC. (A) Compared with tumor tissues from patients with gemcitabine-sensitive TNBC, miR-620 expression levels were elevated in tumor tissues from patients with gemcitabine-resistant TNBC. (B) DCTD expression levels were increased in tumor tissues from patients with gemcitabine-resistant TNBC patients. (C) A negative correlation between miR-620 and DCTD mRNA expression levels in tumor tissues from patients with TNBC. **P<0.01 and ***P<0.001 vs. gemcitabine-sensitive. TNBC, triple negative breast cancer; miR, microRNA; RT-qPCR, reverse transcription-quantitative polymerase chain reaction.
