Figure 3. Reduced expression of miR-378a-3p in clinical breast cancer tissues is associated with poor prognosis for tamoxifen-treated patients.
(a) Decreased miR-378a-3p expression levels in breast cancer tissues compared with those in paired adjacent normal tissues. miR-378a-3p expression levels were determined by qPCR and normalized to RNU48 levels. **P < 0.01. (b) Kaplan-Meier survival analysis according to miR-378a-3p levels in tamoxifen-treated breast cancer patients. The recurrence free survival of miR-378a-3p high-expressing group (n = 74) was significantly lower than that of the low-expressing group (n = 35; log-rank test; P = 0.012).
