Metastasis, invasion and angiogenesis are major features of advanced prostate cancer, which contribute to its poor prognosis. The RUNX3 gene, encoding a transcription factor, has been identified as a novel tumor suppressor gene in various human cancers. Previous studies have indicated that RUNX3 gene expression is decreased in prostate cancer tissues, and its downregulation is associated with tumor progression and metastasis. However, the precise roles and molecular mechanisms of RUNX3 gene in prostate cancer cell migration, invasion and angiogenesis remain largely unknown.Objectives:1. To investigate the expression levels of RUNX3 gene in prostate cancer tissues and its correlation with clinicopathological parameters.2. To explore the effects of RUNX3 gene overexpression or knockdown on prostate cancer cell migration, invasion and angiogenesis in vitro.3. To elucidate the underlying molecular mechanisms of RUNX3 gene-mediated regulation of prostate cancer progression.Methods:1. Quantitative RT-PCR and Western blotting will be used to detect the expression levels of RUNX3 gene in prostate cancer tissues and cell lines.2. Cell migration and invasion assays will be performed to assess the effect of RUNX3 gene overexpression or knockdown on prostate cancer cell motility and invasiveness.精品文档---下载后可任意编辑3. Tube formation assay will be used to evaluate the effect of RUNX3 gene on angiogenesis.4. Immunofluorescence staining and co-immunoprecipitation will be performed to investigate the potential molecular mechanisms of RUNX3 gene in regulating prostate cancer progression.Expected outcomes:This study will provide a comprehensive understanding of the role and molecular mechanisms of RUNX3 gene in prostate cancer cell migration, invasion and angiogenesis, which may provide a potential therapeutic target for the treatment of advanced prostate cancer.
