Member of the driver protein family 18B (KIF18B) is a potential prognostic marker and highly expressed in variety cancers. However, its function glioblastoma (GBM) remains unclear. The expression data KIF18B were obtained by accessing TCGA, CGGA GEPIA databases, verified Western blot assay immunohistochemistry.

Decoding the Role of CDCA Genes in Breast Cancer Progression: Insights From in Silico and Functional Assay

Asia-Pacific Journal of Clinical Oncology, Journal Year: 2025, Volume and Issue: unknown

Published: April 17, 2025

ABSTRACT Background The cell division cycle‐associated (CDCA) genes regulate key cellular processes like cycle progression and division. This study evaluates the diagnostic clinical relevance of CDCA in breast cancer. Methodology Breast cancer normal lines were cultured analyzed for gene expression using RT‐qPCR further validated public databases. Functional assays, including proliferation, colony formation, wound healing, performed following siRNA‐mediated knockdown CDCA2 CDCA3. Mutational, CNV, methylation, survival analyses, along with miRNA regulation PPI network construction, conducted to explore role progression. Results Our findings revealed significant upregulation compared controls, all these exhibiting highest potential based on AUC values ROC analysis. Pathological stage analysis indicated that CDCA5 CDCA7 significantly varied across different stages. Mutational showed had mutation rate, missense mutations being most common. CNV amplification events several genes, particularly CDCA2, CDCA3, CDCA4, CDCA7. Promoter methylation hypomethylation cancer, which correlated negatively their expression. Survival demonstrated high CDCA5, CDCA7, CDCA8 was associated worse overall survival, highlighting prognostic significance. Furthermore, immune infiltration correlations between types, suggesting a modulation. identified specific miRNAs targeting showing as biomarkers. Lastly, CDCA3 cells reduced migration, indicating critical roles tumor growth metastasis. Conclusion highlights promising biomarkers Their correlates poor impairs growth, emphasizing therapeutic targets. These suggest could be integrated into practice improved management.
