PROBLEM: Tokishakuyakusan (TSS) is a traditional Japanese Kampo medicine widely used to support pregnancy; however, its molecular mechanisms remain poorly understood. This study aimed to elucidate the progesterone-related immunomodulatory m…

Ovarian clear cell carcinoma (OCCC) is a chemoresistant subtype of epithelial ovarian cancer with limited therapeutic options and distinct molecular features. Histone methyltransferase SETD8 catalyzes the monomethylation of histone H4 at ly…

Tokishakuyakusan (TSS), a traditional Japanese Kampo medicine, is known for its anti-inflammatory and anti-angiogenic properties. This study examined the effects of TSS on fecundity and endometriosis-like lesions during pregnancy in a murin…

Although ovarian endometrioid carcinoma (OEC), frequently associated with endometrial endometrioid carcinoma (EEC), is often diagnosed at an early stage, the prognosis remains poor. The development of new, effective drugs to target these ca…

The cellular origin of clear cell ovarian carcinoma (CCOC), a major histological subtype of ovarian carcinoma remains elusive. Here, we explored the candidate cellular origin and identify molecular subtypes using integrated genomic/epigenom…

The purpose of this study is to clarify the metabolic dependence of ovarian clear cell carcinoma (CCC) by comparing normal tissues and to examine the applicability of fluorescence imaging probe to exploit these metabolic differences. Enhanc…

Recently, artificial intelligence (AI) has been applied in various fields due to the development of new learning methods, such as deep learning, and the marked progress in computational processing speed. AI is also being applied in the medi…

BACKGROUND: Endometriosis is assumed to be involved in ovarian cancer development, which is called endometriosis-associated ovarian cancer (EAOC). Uterine endometrial cells may be the cell of origin of EAOC. Accumulated carcinogenic changes…

Abstract Background: The purpose of this study was to establish a novel mouse model of adenomyosis suitable for longitudinal and quantitative analyses and perinatal outcome studies. Methods: Using a 30 G needle, the entire ute…

The purpose of this study was to establish a novel mouse model of adenomyosis suitable for longitudinal and quantitative analyses and perinatal outcome studies. Using a 30 G needle, the entire uterine wall of one horn was mechanically punct…

The purpose of this study was to establish a new mouse model of endometriosis that mimics real-world women's health problems, in which women continue to be affected by endometriosis long before they wish to become pregnant, and to evaluate …

OBJECTIVES: This study aimed to determine the systemic and local proportions, focal localization, and characteristics of polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) in endometriosis. STUDY DESIGN: Peripheral blood and pe…

OBJECTIVES: To evaluate the anti-inflammatory and anti-angiogenetic effects of Tokishakuyakusan (TSS), a traditional Japanese medicine (Kampo), and its ingredients, ferulic acid (FA) and paeoniflorin (PA) on endometriotic stromal cells (ESC…

Previous studies have suggested that histone methylation can modulate carcinogenesis and cancer progression. For instance, the histone methyltransferase SET and MYND domain containing 2 (SMYD2) is overexpressed in several types of cancer ti…

Non-hormonal therapeutic strategies for endometriosis are needed. The aim of this study was to characterize the effects of prostaglandin (PG)E2 receptor inhibitors to explore their potential as novel therapeutic strategies for endometriosis…

CONTEXT: The ovarian reserve is reduced in patients with endometriosis. We hypothesize that the phosphatidylinositol 3-kinase (PI3K)-phosphatase and tensin homolog deleted on chromosome 10 (PTEN) Akt-Forkhead box O (Foxo3) pathway is involv…

Uterine adenomyosis is a benign disorder that often co-occurs with endometriosis and/or leiomyoma, and impairs quality of life. The genomic features of adenomyosis are unknown. Here we apply next-generation sequencing to adenomyosis (70 ind…

A cotyledonoid dissecting leiomyoma (CDL) is a rare variant of a uterine smooth muscle cell tumor and is characterized by intramural and extrauterine growth patterns with dissection of the uterine myometrium.We encountered a case of a CDL w…

OBJECTIVE: The aim of this study was to clarify the expression of Ninj1 in endometriosis and adenomyosis lesions, and its inductive factor in human endometriotic stromal cells (ESCs). BACKGROUND: Nerve injury-induced protein 1 (Ninj1) is a…

Endometriosis is characterized by the implantation and growth of endometriotic tissues outside the uterus. It is widely accepted the theory that endometriosis is caused by the implantation of endometrial tissue from retrograde menstruation;…
