PGR and neoplasm: NK1R‐Tr was significantly overexpressed in oestrogen receptor (ER)− and progesterone receptor (PR)− positive tumours (P = 0.041 and P = 0.047, respectively); however, there was no difference in miR‐34b/c‐5p expression (miR‐34b‐5p, P = 0.581, P = 0.791; miR‐34c‐5p, P = 0.771, P = 0.265) or in NK1R‐FL expression (P = 0.864, P = 0.338).
