IntroductionTamoxifen (TAM) is a well-established treatment for hormone receptor-positive breast cancer with a known side-effect profile that includes hot flashes, genital bleeding, and diarrhea (0.1%-5%). Other notable side effects include…

The most common medical therapy for endometriosis suppresses ovulation, which is a barrier for patients planning pregnancy. To address this issue, we focused on the cell proliferation-suppressing effects of lactoferrin, which reportedly in …

Introductionvon Hippel-Lindau (VHL) disease is an autosomal dominant hereditary disorder characterized by the development of tumor-like lesions in multiple organs. While central nervous system hemangioblastomas, pancreatic neuroendocrine tu…

Endometriosis is an estrogen-dependent disorder defined as the deposition and growth of endometrial tissue outside the uterus, including but not limited to the pelvic peritoneum, rectovaginal septum, and ovaries. Endometriosis is a substant…

BACKGROUND: Cesarean scar defects (CSD) are caused by cesarean sections and cause various symptoms. Although there has been no previous consensus on the name of this condition for a long time, it has been named cesarean scar disorder (CSDi)…

Endometriosis is a common condition associated with debilitating pelvic pain and infertility. A genome-wide association study meta-analysis, including 60,674 cases and 701,926 controls of European and East Asian descent, identified 42 genom…

Uterine leiomyoma is one of the most common gynaecologic benign tumours, but its genetic basis remains largely unknown. Six previous GWAS identified 33 genetic factors in total. Here, we performed a two-staged GWAS using 13,746 cases and 70…

Ovarian clear cell carcinoma (OCCC) exhibits distinct phenotypes, such as resistance to chemotherapy, poor prognosis and an association with endometriosis. Biomarkers and imaging techniques currently in use are not sufficient for reliable d…

STUDY QUESTION: Are single-nucleotide polymorphisms (SNPs) at the interleukin 1A (IL1A) gene locus associated with endometriosis risk? SUMMARY ANSWER: We found evidence for strong association between IL1A SNPs and endometriosis risk. WHAT I…

PROBLEM: Endometriosis is recognized as a chronic inflammatory disease and is related to immune response. There have been reports that revealed the different distribution of macrophage within the eutopic endometrium of women with endometrio…

OBJECTIVE: To evaluate the association between endometriosis and chronic endometritis. METHODS: Endometrial specimens were obtained from 71 patients, 34 with endometriosis (endometriosis group) and 37 without endometriosis (non-endometriosi…

Age at menarche (AAM) is a complex trait involving both genetic and environmental factors. To identify the genetic factors associated with AAM, we conducted a large-scale meta-analysis of genome-wide association studies using more than 15,0…

Peptic ulcer is one of the most common gastrointestinal disorders with complex etiology. Recently we conducted the genome wide association study for duodenal ulcer and identified disease susceptibility variations at two genetic loci corresp…

Although the pathogenesis of endometriosis is not well understood, genetic factors have been considered to have critical roles in its etiology. Through a genome-wide association study and a replication study using a total of 1,907 Japanese …
