AB Objective: To study the expression levels of tachykinins and tachykinin receptors in uterine leiomyomas and matched myometrium.Design: Laboratory study.Setting: University research laboratories and academic hospital.Patient(s): Women undergoing hysterectomy for symptomatic leiomyomas.Intervention(s): Quantitative polymerase chain reaction, immunohistochemistry and Western blot.Main Outcome Measure(s): Expression and tissue immunostaining of substance P, neurokinin A, hemokinin-1, neurokinin 1 receptorfull-length (NK1R-Fl) and truncated (NK1R-Tr) isoforms, and neurokinin 2 receptor (NK2R) in paired samples of leiomyoma andadjacent normal myometrium.Result(s): TAC1 messenger RNA (mRNA) was significantly up-regulated in leiomyomas, whereas intense immunoreaction for the threepeptides was particularly abundant in connective tissue cells. Differential regulation of TACR1 mRNA was observed, and at the proteinlevel there was a significant increased expression of NK1R short isoform (NK1R-Tr). TACR2 mRNA was significantly up-regulated inleiomyomas, although levels of NK2R protein were similar in normal and tumor cells.Conclusion(s): These and our previous data demonstrate that the whole tachykinin system is differentially regulated in leiomyomas.The increased expression of NK1R-Tr might stimulate leiomyoma growth in a similar way to that observed in other steroid-dependenttumors.
