Expression and significance of transforming growth factor β-activated kinase 1 in uterine myoma tissue

摘要

Objective:To compare the expression of TAK1 in normal myometrium and uterine leiomyoma tissue, and explore the relationship between these molecules and pathogenesis of uterine leiomyoma. Methods:Formaldehyde-fixed, paraffin-embedded specimen from 76 patients with uterine leiomyoma and normal myometrium adjacent were obtained from our hospital. The expression of TAK1 was detected by immunohistochemical staining and PCR analysis. Results:The expression of protein and mRNA levels TAK1 in uterine leiomyoma tissues were significantly increased when compared with normal myometrium, but not related to the number of leiomyoma. Furthermore, TAK1 expression was associated with the size of uterine leiomyoma. Conclusion:The present results suggest that the abundant expression of TAK1 protein may have a molecular basis characteristic of leiomyomas in the human uterus, and TAK1 may be a therapeutic target for the treatment of uterine leiomyoma.
