Background & Objective: It was reported that vascular cell adhesion molecule-1 (VCAM-1) was highly expressed in ovarian carcinoma samples. The latest research showed that the concentration of serum soluble VCAM-1 (sVCAM-1) was increased in the patients with various tumors. The aim of this study was to investigate the biological effects of sVCAM-1 on epithelial ovarian carcinoma.
Methods: The concentration of serum sVCAM-1 was assayed in 130 normal cases, 50 benign ovarian tumors, and 67 epithelial ovarian carcinoma cases using enzyme-linked immunoadsorbent assay(ELISA).
Results: The serum sVCAM-1 level in epithelial ovarian carcinoma[(897+/-54) g/L,83.6%] was higher than those in benign ovarian tumor [(435+/-43) g/L, 8.0%] and normal cases [(420+/-40) microg/L,6.2%] (P< 0.01), while the former dropped post-operation [(532+/-46) microg/L,37.3%]. The serum sVCAM-1 levels in stage II-IV [(899+/-71) microg/L,93.3%], grade III [(982+/-66) microg/L,94.8%], and the cases combined with lymphatic metastasis [(895+/-58) microg/L,95.1%] were higher than those in stage I[(571+/-49) microg/L,63.6%], grade I [(641+/-51)microg/L,69.2%], grade II[(768+/-47)microg/L,66.7%], and the cases without lymphatic metastasis[(728+/-47) microg/L,65.4%](P< 0.05, P< 0.01, and P< 0.01, respectively); while no correlation was found between serum sVCAM-1 levels and histological types (P >0.5). No correlation was found between concentration of sVCAM-1 and prognosis by multiple factor analysis.
Conclusion: Dynamically monitoring the concentration of serum sVCAM-1 will hopefully become an index for early diagnosis and supervising the recurrence of epithelial ovarian carcinoma.

Reprogramming tryptophan metabolism (TRP) may be able to overcome immunosuppression and restore the immune checkpoint blockade (ICB) response in patients with epithelial ovarian cancer (EOC) resistant to ICB therapy because TRP metabolism is involved in the kynurenine/indole and serotonin pathways of tryptophan metabolism. Herein, employing amitriptyline (AMI), an antagonist of TLR4 and serotonin transporter (SERT), we revealed that AMI remodels the immunological landscape of EOC. In particular, AMI lowered the expression of IDO1, IL-4I1, and PD-L1, the quantity of KYN and indoles, and the level of immunosuppressive immune cells MDSC, Tregs, and CD8CD39+/PD-1+ T cell.

Mucinous ovarian cystadenomas are rare epithelial benign tumors that can reach significant sizes. They are often asymptomatic and are discovered incidentally during an ultrasound examination. We present two clinical cases of mucinous ovarian cystadenomas with abdominal distention.

Background: To assess the effectiveness of tumor biomarkers in distinguishing epithelial ovarian tumors (EOTs) and guiding clinical decisions across each Ovarian-Adnexal Reporting and Data System (O-RADS) MRI risk category, the aim is to prevent unnecessary surgeries for benign lesions, avoid delays in treating malignancies, and benefit individuals requiring fertility preservation or those intolerant to over-extensive surgery.
Methods: A total of 54 benign, 104 borderline, and 203 malignant EOTs (BeEOTs, BEOTs and MEOTs) were enrolled and retrospectively assigned risk scores. The role of tumor biomarkers in diagnosing and managing EOTs within each risk category was evaluated by combining receiver operating characteristic (ROC) curves with clinicopathological characteristics.

The fallopian tube undergoes extensive molecular changes during the menstrual cycle and menopause. We use single-cell RNA and ATAC sequencing to construct a comprehensive cell atlas of healthy human fallopian tubes during the menstrual cycle and menopause. Our scRNA-seq comparison of 85,107 pre- and 46,111 post-menopausal fallopian tube cells reveals substantial shifts in cell type frequencies, gene expression, transcription factor activity, and cell-to-cell communications during menopause and menstrual cycle.
