Article Abstract
Background: Endometrial carcinoma (EC) is a malignant tumor of the female reproductive tract that has been associated with increased morbidity and mortality. This study aimed to identify biomarkers and potential therapeutic targets for EC.
Methods: A publicly available transcriptome data set comprising 587 EC cases was subjected to a comprehensive bioinformatics analysis to identify candidate genes responsible for EC occurrence and development. Next, we used clinical samples and cell experiments for validation.
Results: A total of 1,617 differentially expressed genes (DEGs) were identified. Analysis of patient survival outcomes revealed that BUB1, BUB1B, CCNA2, and CDCA8 were correlated with prognosis in patients with EC. Moreover, assessment of clinical samples confirmed that BUB1, BUB1B, CCNA2 and CDCA8 were strongly expressed in EC tissues. Additionally, bioinformatics and luciferase reporter assays confirmed that miR-524-5p can target and regulate these four genes. Overexpression of miR-524-5p significantly inhibited EC Ishikawa cells viability, migration and invasion. Inhibition of miR-524-5p showed the opposite results.
Conclusions: Expression of miR-524-5p reduced the migration and invasion of Ishikawa EC cells, and decreased BUB1, BUB1B, CCNA2, and CDCA8 expression. miR-524-5p, as well as BUB1, BUB1B, CCNA2, and CDCA8, may be clinically relevant biomarkers for the diagnosis and treatment of EC.

Radioresistance is a major obstacle to effective radiotherapy in breast cancer. BUB1 mitotic checkpoint serine/threonine kinase B (BUB1B) is involved in numerous biological processes associated with cancer; however, its specific role in mediating radioresistance in breast cancer remains poorly characterized. The present study first evaluated its expression profile and association with patient prognosis through bioinformatics analysis.

Wuding chicken, an indigenous avian breed native to China, is known for its high-quality meat and eggs. However, it has a low egg production rate, poor reproductive traits, and strong broody behavior. Ovarian follicle development is essential for egg production and reproduction, being regulated by the hypothalamus-pituitary-ovary (HPO) axis.

Background/aim: While normal cells are highly regulated, cancer cells take a dysregulated path which bolsters their survival. Currently, a limited number of uniform treatments are available for cancer cure. Our goal was to deprive cancer cells of the key nutrient methionine and determine what effect it would have on cell death and alterations in DNA methylation of prostate cancer cells.

Objective: To explore the genetic etiology of two fetuses with Mosaic variegated aneuploidy syndrome (MVA) in a pedigree.
Methods: A 30-year-old pregnant woman, who presented at the Center for Medical Genetics and Prenatal Diagnosis of Shandong Maternal and Child Health Care Hospital on November 16, 2023, was enrolled. Clinical data of the pedigree were collected, and peripheral blood samples from the parents and amniotic fluid samples from the two fetuses were obtained for genomic DNA extraction.
