Abstract
Adenomyosis is a prevalent gynecologic benign disease in women. Despite its significance, there is only a limited understanding of its pathological mechanisms. Talin1, a cytoskeletal protein, plays an important role in cell survival, proliferation, invasion and migration. The objective of this study was to investigate the mRNA and protein expression of talin1 in both the eutopic and ectopic endometria of women with adenomyosis. Higher talin1 mRNA levels were observed in both ectopic and eutopic endometria from the adenomyosis subjects compared with the eutopic endometria from women without adenomyosis. Immunohistochemistry revealed increased epithelial expression of talin1 in the ectopic and eutopic endometria from patients with adenomyosis compared with those without adenomyosis. When tests were performed on matched samples of eutopic and ectopic endometria of adenomyosis subjects, the mRNA and protein expression of talin1 was much higher in the ectopic endometria than in the eutopic endometria. The results reveal that the expression pattern of talin1 in the eutopic and ectopic endometria is enhanced in women with adenomyosis. Increased talin1 expression may play a role in the pathogenesis and development of adenomyosis.
