TACR1 and breast cancer: Among them, miR‐34b/c‐5p and NK1R‐FL were significantly overexpressed in normal breast tissues (P < 0.001).35 Conversely, NK1R‐Tr expression was significantly overexpressed in breast cancer tissues (P = 0.0023).22 As shown in Table 1, we quantified miR‐34b/c‐5p and NK1R expression in tumour samples from 50 breast cancer patients.
