Previous study from our and other laboratory reported that Aurora‐A plays an important role in drug resistance.46, 47, 48 Aurora‐A stabilizes survivin in gastric cancer to promote drug resistance.49 High expression level of Aurora‐A was involved in tamoxifen resistance.46 In the present study, we demonstrated that high levels of Aurora‐A offer TNBC cells an additional growth advantage and protection against paclitaxel. Here, BIRC5 is linked to gastric cancer.
