Objective: The objective of this study was to determine if the Src tyrosine kinase is overexpressed and activated in late-stage human ovarian cancers.
Methods: Western analysis and immune complex kinase assays were performed on a panel of human ovarian cancer cell lines and normal ovarian epithelial cell cultures, and immunohistochemical analysis for Src and activated Src were performed on a panel of late-stage human ovarian tumors.
Results And Conclusions: Src is overexpressed and activated in a majority of late-stage ovarian tumors as well as in a panel of cultured malignant human ovarian epithelium grown in vitro, but not in normal ovarian epithelium (NOE) or immortalized NOE. Src overexpression was found to be frequently, but not always, associated with HER-2/neu overexpression, but no statistical association between Src and Her-2/neu overexpression could be demonstrated.
Polycystic ovary syndrome (PCOS), a major cause of female infertility, affects 4%-20% of reproductive-age women. Metabolic and hormonal alterations are key features of PCOS, potentially raising the risk of endometrial (EC) and ovarian (OVCA) cancers. This systematic review aims to summarise the proposed molecular mechanisms involved in the association between PCOS and EC or OVCA.

Background: Ovarian cancer (OC) is a heterogeneous malignancy with multiple histological subtypes, showing global variability in incidence. Temporal changes in diagnostic criteria and risk factors might influence the incidence and distribution of OC and its subtypes.
Methods: This study analyzed incidence patterns (2013-2017) and trends (1988-1992 to 2013-2017) of OC and its subtypes across 65 and 40 countries, respectively.
Objective: To investigate the association between thyroid dysfunction or thyroid autoimmunity (TAI) and diminished ovarian reserve (DOR).
Methods: A total of 2,867 women undergoing their first fertilization (IVF) cycle at Shenzhen Zhongshan Obstetrics & Gynecology Hospital between January 1, 2013 and June 30, 2021, were enrolled in this study. The participants had documented thyroid and ovarian reserve metrics.
Ovarian cancer (OC) is prone to adipose tissue metastasis. However, the underlying molecular mechanisms remain elusive. Here, we observed that omental adipocytes were induced into cancer-associated adipocytes (CAAs) by OC-derived TGF-β1 to establish a pre-metastatic niche (PMN) through collagen and fibronectin secretion.

Study Question: Is the probability of pregnancy different between women using biosimilars versus the originator of follitropin alfa for ovarian stimulation in ART?
Summary Answer: Meta-analysis of eight randomized clinical trials (RCTs) suggests that live birth, clinical, and ongoing pregnancy rates are significantly lower with biosimilars of follitropin alfa compared to the originator.
What Is Known Already: All biosimilars of follitropin alfa have received regulatory approval by demonstrating non-inferiority in the number of retrieved oocytes compared to the originator. Nevertheless, the most clinically relevant outcome in ART for both clinicians and patients is live birth.
