Background: Ovarian cancer is one of the most common tumors affecting females, significantly disrupting their quality of life. Agrimonolide, an extract derived from Agrimony (Agrimonia pilosa Ledeb.), has been shown to exert various regulatory effects on several diseases. Notably, recent studies indicate that Agrimonolide may attenuate the progression of ovarian cancer. However, the detailed regulatory mechanisms of Agrimonolide in this context require further investigation.
Purpose: To determine the significance of HIF1A as a key target in ovarian cancer and its potential underlying signaling pathway.
Methods: Cell viability and proliferation were assessed using CCK-8 and colony formation assays. Glucose uptake and lactate production were measured using commercial kits, and the extracellular acidification rate (ECAR) was evaluated. Protein expression levels were analyzed through western blotting.
Results: Our network pharmacology analysis identified HIF1A as a crucial target and signaling pathway in ovarian cancer. Furthermore, treatment with Agrimonolide (20 μM and 40 μM) inhibited the growth of ovarian cancer cells. Agrimonolide also reduced glycolytic activity in these cells. Additionally, Agrimonolide treatment led to decreased expression levels of HIF1A, HK2, and LDHA in ovarian cancer cells. Rescue assays revealed that glucose uptake and lactate production were diminished following Agrimonolide treatment; however, these effects were reversed upon overexpression of HIF1A.
Conclusion: This study showed that Agrimonolide can suppress glycolysis in ovarian cancer cells by modulating HIF1A, supporting Agrimonolide as a promising therapeutic agent for ovarian cancer treatment.

Purpose: Signal transducer and activator of transcription 3 (STAT3) is a transcription factor that is essential for the survival and immune sequestration of cancer cells. We conducted a phase 1 study of TTI‑101, a first-in-class, selective small-molecule inhibitor of STAT3, in patients with advanced metastatic cancer.
Patients And Methods: Patients were treated with TTI-101 orally twice daily in 28-day cycles at 4 dose levels (DLs): 3.

Purpose: Ovarian clear cell carcinoma is a highly malignant gynecological tumor characterized by a high rate of chemotherapy resistance and poor prognosis. The PI3K/AKT/mTOR pathway is well-known to be closely related to the progression of various malignancies, and recent studies have indicated that this pathway may play a critical role in the progression and worsening of OCCC.
Methods: In this study, we investigated the combined effects of WX390, a dual inhibitor of PI3K/mTOR, and cisplatin on OCCC through both in vitro and in vivo experiments to further elucidate their therapeutic effects.

Ubiquitin-conjugating enzyme E2 T (UBE2T) is a crucial E2 enzyme in the ubiquitin-proteasome system (UPS), playing a significant role in the ubiquitination of proteins and influencing a wide range of cellular processes, including proliferation, differentiation, apoptosis, invasion, and metabolism. Its overexpression has been implicated in various malignancies, such as lung adenocarcinoma, gastric cancer, pancreatic cancer, liver cancer, and ovarian cancer, where it correlates strongly with disease progression. UBE2T facilitates tumorigenesis and malignant behaviors by mediating essential functions such as DNA repair, apoptosis, cell cycle regulation, and the activation of oncogenic signaling pathways.
