Objective: To investigate the expression of metastasis-associated in colon cancer-1 (MACC1) in different International Federation of Gynecology and Obstetrics(FIGO)stages of epithelial ovarian cancer and its relationship with prognosis.
Methods: Between May 2008 and August 2010, 52 epithelial ovarian cancer patients were selected from the Department of Obstetrics and Gynecology of the First Affiliated Hospital of Zhengzhou University. Reverse transcription polymerase chain reaction (RT-PCR) and Western blotting were used to detect the expression of MACC1 mRNA and protein in the primary lesions of epithelial ovarian cancer patients, the levels of MACC1 in different stage patients were compared, and the relationship between expression of MACC1 and prognosis of ovarian cancer patients was analyzed by Kaplan-Meier analysis.
Results: The relative expression levels of MACC1 mRNA in epithelial ovarian cancer from 1 stage to 4 stage were 0.72±0.01, 0.75±0.01, 0.78±0.01, and 0.81±0.02, respectively (F=51.305, P=0.000). The expression levels of MACC1 protein from 1 stage to 4 stage were 0.71±0.04, 0.73±0.02, 0.76±0.01, and 0.84±0.05, respectively (F=65.142, P=0.000). At the end of the follow-up, the expression of MACC1 protein in recurrence and dead patients of 3-4 stages was obviously higher than that in the patients with stable disease (0.85±0.03 vs.0.74±0.05, F=72.324, P=0.000). Compared to 1-2 stage patients with lower MACC1 expression, the survival time of 3-4 stage patients with higher MACCC1 expression was significantly shorter (χ(2)=29.804, P=0.000).
Conclusions: Increased expression of MACC1 may indicate poor prognosis of ovarian cancer patients. Therefore, MACC1 may be a potential biomarker for advanced ovarian cancer.

Objective: He Shi Yu Lin Formula (HSYLF) is a clinically proven prescription for treating premature ovarian insufficiency (POI), and has shown a good curative effect. However, its molecular mechanisms are unclear. This study aimed to investigate the molecular mechanisms of HSYLF and clarify how network pharmacology analysis guides the design of animal experiments, including the selection of effective treatment doses and key targets, to ensure the relevance of the experimental results.

Ovarian cancer (OvCa) is the most lethal gynaecology malignancies worldwide. Neutrophil extracellular traps (NETs), net-like protein structures produced by activated neutrophils and DNA-histone complexes, have a central role in tumours, though haven't been fully explored in OvCa. We obtained transcriptome data from TCGA-OvCa database (n = 376) as training, ICGC-OvCa database (n = 111) as validation and GTEx database (n = 180) as controls.

Objective: The purpose of this study was to evaluate MRI findings of ovarian endometrioid carcinoma (OEC) as a predictor of histological grade.
Materials And Methods: This study included 60 patients with histopathologically confirmed OEC (20, 30, and 10 with grades 1, 2, and 3, respectively). Clinical and MRI results were retrospectively reviewed.

MYD88 is an IL-6 primary response gene and, its upregulation of expression has been shown to be a poor prognostic factor in epithelial ovarian cancer (EOC). We investigated the effects of CpG methylation at the proximal promoter/5'UTR and IL-6/SP1/IRF1 signaling on upregulation of MYD88 and prognosis in EOC. We assessed CpG methylation at the proximal promoter/5'UTR of MYD88 using bisulfite sequencing/PCR in 103 EOC patients, 28 normal ovarian tissues and two EOC cell lines with differential expression of MYD88 and identified the impact of the level of CpG methylation on MYD88 upregulation by SP1/IRF1 with knockdown or blockade of IL-6.

Ovarian cancer is known to be a challenging disease to detect at an early stage and is a major cause of death among women. The current treatment for ovarian cancer typically involves a combination of surgery and the use of drugs such as platinum-based cytotoxic agents, anti-angiogenic drugs, etc. However, current treatment methods are not always effective in preventing the recurrence of ovarian cancer.
