Background: Overexpression of Inhibitor of DNA-binding 1 protein (ID-1) is correlated with poor prognosis in some malignancies and few studies have assessed its role in ovarian cancer. This led us to investigate its association with the microvessel density (MVD) in patients with ovarian cancer.
Materials And Methods: Fifty-six patients with epithelial serous ovarian cancer were selected. The early-stage group consisted of 14 patients and the advanced-stage group comprised 42 patients. ID-1 expression and MVD were evaluated by immunohistochemistry.
Results And Conclusion: The histoscore for ID-1 and MVD were significantly higher in advanced-stage cancer (p<0.05). The MVD was significantly higher in the high ID-1 expression group compared to the low ID-1 expression group (p<0.001). The mean follow-up time was 52 months. The survival period in patients with high ID-1 expression was not significantly shorter than for those with low ID-1 expression (p=0.62). The role of ID-1 protein requires further investigation.

Introduction Evidence suggests inflammation plays a key role in the development of ovarian malignancy. This study investigated the relationship between the C-reactive protein (CRP) to serum albumin (Alb) ratio and clinicopathological parameters in ovarian cancer patients. The goal was to determine if this readily measurable inflammatory marker could provide insights into disease severity.

Autoimmune cerebellar ataxia (ACA) is a cerebellar syndrome induced by autoimmune reactions and its onset is induced by malignant tumors, prodromic infection, and gluten allergy. Its clinical symptoms include gait disorder, limb ataxia, dysarthria, and dysphagia. According to , the diagnosis of ACA is based on the following points: 1.

Drug repositioning, the practice of identifying novel applications for existing drugs beyond their originally intended medical indications, stands as a transformative strategy revolutionizing pharmaceutical productivity. In contrast to conventional drug development approaches, this innovative method has proven to be exceptionally effective. This is particularly relevant for cancer therapy, where the demand for groundbreaking treatments continues to grow.

Background: Immune cells within tumor tissues play important roles in remodeling the tumor microenvironment, thus affecting tumor progression and the therapeutic response. The current study was designed to identify key markers of plasma cells and explore their role in high-grade serous ovarian cancer (HGSOC).
Methods: We utilized single-cell sequencing data from the Gene Expression Omnibus (GEO) database to identify key immune cell types within HGSOC tissues and to extract related markers via the Seurat package.
