To study the pathological contribution of fatty acid (FA) metabolism regulators including fatty acid binding protein 4 (FABP4), FABP5, peroxisome proliferator-activated receptor alpha (PPARα), and PPARγ in ovarian carcinoma, non-cancerous h…

The bicellular tight junction molecule cingulin (CGN) binds to microtubules in centrosomes. Furthermore, CGN contributes to the tricellular tight junction (tTJ) proteins lipolysis-stimulated lipoprotein receptor (LSR) and tricellulin (TRIC)…

PURPOSE: Following the COVID-19 pandemic, group A Streptococcus (GAS) infection has been surging worldwide. We aimed to compare the disease burden between notified cases of streptococcal toxic shock syndrome (STSS) and unreported GAS infect…

PURPOSE: The NY-ESO-1 antigen is highly immunogenic and often spontaneously induces an immune response in patients with cancer. We conducted a large-scale multicenter cohort study to investigate the utility of serum NY-ESO-1 and p53 antibod…

It is known that there are abnormalities of tight junction functions, cell migration and mitochondrial metabolism in human endometriosis and endometrial carcinoma. In this study, we investigated the effects of growth factors and their inhib…

Among drug-induced adverse events, pancreatitis is life-threatening and results in substantial morbidity. A prototype example is the pancreatitis caused by asparaginase, a crucial drug used to treat acute lymphoblastic leukemia (ALL). Here,…

A uteroperitoneal fistula (UPF) is a rare disorder that can lead to infertility and has never been reported. UPFs can cause infertility and perinatal complications. A 34-year-old woman (gravida 0) with a history of three gynecological surge…

BACKGROUND: Endometrial cancer (EC) is one of the leading causes of cancer death among women and early detection is crucial for its successful treatment. We previously showed that cytological examination combined with genetic analysis using…

Lipolysis-stimulated lipoprotein receptor (LSR), a lipid metabolism-related factor localized in tricellular tight junctions (tTJs), plays an important role in maintaining the epithelial barrier. LSR is highly expressed in well-differentiate…

INTRODUCTION: Infertility is estimated to affect 8% to 12% of reproductive-aged couples worldwide. While approximately 85% of infertile couples have an identified cause, the remaining 15% suffer physically and emotionally from unexplained i…

BACKGROUND: Menstrual blood-derived cells show regenerative potential as a mesenchymal stem cell and may therefore be a novel stem cell source of treatment for refractory infertility with injured endometrium. However, there have been few pr…

OBJECTIVES: The aim of this study was to compare preoperative imaging evaluation results and postoperative histopathology examinations of patients who underwent laparoscopic- or robot-assisted surgery for suspected Stage IA endometrial carc…

Tight junction proteins play roles beyond permeability barriers functions and control cell proliferation and differentiation. The relation between tight junctions and the signal transduction pathways affects cell growth, invasion and migrat…

Apoptosis-stimulating p53 protein 2 (ASPP2) is an apoptosis inducer that acts via binding with p53 and epithelial polarity molecule PAR3. Lipolysis-stimulated lipoprotein receptor (LSR) is an important molecule at tricellular contacts, and …

Claudin-2 (CLDN-2) is a leaky-type tight junction protein, and its overexpression increases tumorigenesis of some types of cancer cells. In the present study, to examine the possibility of targeting CLDN-2 in the therapy for endometrioid en…

Low-grade endometrial stromal sarcoma (LG-ESS) is a rare uterine tumor that sometimes recurs and advances. Hormonal treatment, especially high-dose progestins and aromatase inhibitors (AIs), has demonstrated efficacy against these tumors. B…

PURPOSE: To evaluate the efficacy of silicone sheet as a new type of barrier for preventing adhesion reformation following hysteroscopic adhesiolysis of intrauterine adhesions (IUAs). METHODS: Hysteroscopic adhesiolysis was performed for 3…

BACKGROUND: The incidence of postoperative nausea and vomiting (PONV) is higher in patients receiving volatile anesthetics than those receiving total intravenous anesthesia (TIVA) with propofol. However, it is unclear whether its incidence …

We herein report two cases of miliary lung metastases from genital carcinoma in uterine cervix and endometrium. Notably, these patients were unable to receive any anti-tumor chemotherapy due to rapid progression causing respiratory failure,…

BACKGROUND: Chronic pancreatitis (CP) is a fibro-inflammatory disease of the pancreas. Early diagnosis and intervention, before CP becomes established and irreversible, are essential to improve the long-term outcomes. The world's first diag…

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…

Although liquid-based cytology (LBC) has increased the sensitivity of cytological diagnosis of endometrial cancer (EC) compared with conventional smear cytology, the sensitivity of LBC for the detection of EC is between 70% and 96% and rema…

Uterine leiomyoma is the most common benign tumour in women, and an appropriate animal model for leiomyoma would be useful for exploring new therapeutic strategies. Therefore, we have been challenged to develop a new simple mouse model for …

BACKGROUND: Vulvar cancer and vaginal cancer are relatively rare tumors, and there had been no established treatment principles or guidelines to treat these rare tumors in Japan. The first version of the Japan Society of Gynecologic Oncolog…
