The objective of this review is to summarize recent research advances in the detection and prevention of ovarian cancer and discuss the experts' opinions of future directions. The 12th Biennial Ovarian Cancer Research Symposium was held in Seattle, Washington, in September 2018. At this meeting, experts in ovarian cancer research gathered to present and discuss recent breakthroughs and their visions of future ovarian cancer research. Session 1 of the symposium focused on the detection and prevention of ovarian cancer. It included two invited oral presentations from Ranjit Manchanda, MD, PhD (Barts Cancer Institute) and Rosana Risques, PhD (University of Washington). Another eight oral presentations were selected from abstract submissions. Fifteen abstracts were presented in poster format. These presentations covered topics including cellular origin of high-grade serous cancer, risk factors for ovarian cancer, new methods for early detection of ovarian cancer, mechanisms underlying ovarian cancer development, and new therapeutic approaches for preventing ovarian cancer from forming or progressing. In conclusion, a clear understanding of the cellular origin and molecular mechanisms underlying the initiation of high-grade serous cancer is essential for developing effective means for early detection and prevention of this most devastating type of ovarian cancer. Recognizing the complexity of ovarian cancer and appreciating that ovarian cancer is not a single disease will help us to generate proper models, design rational experiments, and collect and analyze patient data in a meaningful way. A concerted effort in the field will help to bridge the basic science and clinical applications and lead to more precise and effective detection and treatment.

Up to 90% of high-grade serous ovarian cancer (HGSC) patients will develop resistance to platinum-based chemotherapy, posing substantial therapeutic challenges due to a lack of universally druggable targets. Leveraging BenevolentAI's AI-driven approach to target discovery, we screened potential AI-predicted therapeutic targets mapped to unapproved tool compounds in patient-derived 3D models. This identified TNIK, which is modulated by NCB-0846, as a novel target for platinum-resistant HGSC.

Background: High-grade serous ovarian cancer (HGSOC) accounts for 70-80% of all ovarian cancer-related deaths. Multiple studies have suggested that the fallopian tube epithelium (FTE) serves as the cell of origin of HGSOC. Phosphatase and tensin homolog () is a tumor suppressor and its loss is sufficient to induce numerous tumorigenic changes in FTE, including increased migration, formation of multicellular tumor spheroids (MTSs), and ovarian colonization.

Background: Ovarian cancer is the leading cause of death among gynaecological cancers. The identification of the fallopian tube epithelium as the origin of most ovarian cancers introduces a novel prevention strategy by removing the fallopian tubes during an already indicated abdominal surgery for another reason, also known as an opportunistic salpingectomy. This preventive opportunity is evidence based, recommended and established at the time of gynaecologic surgery in many countries worldwide.

Despite a high burden of osteoporosis and minimal trauma fractures worldwide, there is still a treatment gap in timely diagnosis and optimal treatment. There is also a lack of international consensus and guidelines on the management of bone fragility in premenopausal women. This review article provides an overview of the current understanding of factors impacting women's bone health across the adult lifespan, as well as dilemmas in the diagnosis, assessment and management of osteoporosis in premenopausal and postmenopausal women, premature ovarian insufficiency and bone health following breast cancer.

Background: Ovarian cancer (OC) remains a lethal gynecological malignancy with an alarming mortality rate, primarily attributed to delayed diagnosis and a lack of effective treatment modalities. Accumulated evidence highlights the pivotal role of reprogrammed lipid metabolism in fueling OC progression, however, the intricate underlying molecular mechanisms are not fully elucidated.
Methods: DLAT expression was assessed in OC tissues and cell lines by immunohistochemistry, western blot and qRT-PCR analysis.
