STUDY QUESTION: Does PIEZO1 play any role in adenomyosis-associated dysmenorrhea? SUMMARY ANSWER: PIEZO1 downregulation in the myometrium reduces the expression of endothelial nitric oxide synthase (eNOS) and nitric oxide (NO) production, …

We investigated whether anogenital distance (AGD) is associated with adenomyosis, endometriosis and uterine leiomyomas (UL, also called uterine fibroids). We recruited 81 women with UL, 105 with ovarian endometrioma (OE), 116 with adenomyos…

So far, the pressing need for the development of non-hormonal therapeutics for endometriosis has been unfulfilled. In light of the evidence that platelets play important roles in the development of endometriosis and that tetramethylpyrazine…

CONTEXT: While fibrosis in endometriosis has recently loomed prominently, the sources of myofibroblasts, the principal effector cell in fibrotic diseases, remain largely obscure. Mesothelial cells (MCs) can be converted into myofibroblasts …

RESEARCH QUESTION: Do endometriotic lesions undergo endothelial-mesenchymal transition (EndoMT)? DESIGN: Lesion samples from 30 patients with ovarian endometriomas and deep endometriosis, and control endometrial tissue samples from 30 wome…

RESEARCH QUESTION: Does sodium tanshinone IIA sulfonate (STS) induce cellular senescence in endometriotic lesions and thus restrict lesional development and fibrogenesis in a recently established mouse model of deep endometriosis? DESIGN: …

Endometriotic lesions are known to be hyperinnervated, especially in lesions of deep endometriosis (DE), which are frequently in close proximity to various nerve plexuses. DE lesions typically have higher fibromuscular content than that of …

STUDY QUESTION: Do sensory nerves play any role in the development of endometriosis? SUMMARY ANSWER: Sensory nerves participate in all major steps (epithelial-mesenchymal transition (EMT), fibroblast-to-myofibroblast transdifferentiation (…

STUDY QUESTION: Is it possible to establish a mouse model of deep endometriosis (DE)? SUMMARY ANSWER: A mouse DE model that is macroscopically and microscopically similar to nodular lesions in humans can be constructed in as short as 3 wee…

Hyperinnervation in endometriosis is now well documented, but so far only a few neurotrophins have been identified. Since endometriotic stromal cells secrete thromboxane A2 (TXA2), we sought to determine whether TXA2, derived from endometri…

One of major objectives in treating endometriosis is to alleviate pain since dysmenorrhea and other types of pain top the list of complaints from women with endometriosis who seek medical attention. Indeed, endometriosis-associated pain (EA…
