NCKIPSD and breast cancer: Taken together, our data collectively suggest that luminal A breast cancer patients with high-level miR-130b-3p expression show poor prognosis, and that miR-130b-3p shows an inverse correlation with SPIN90 in fibroblasts from human breast tumor tissues, with high significance (p = 1.88E−10, r = −0.6634) (Fig. 6D).
