Abstract
The Filamin C (FLNC) gene, pivotal for cellular structure and function, holds significance in cancer biology. We conducted a comprehensive study using various analytical approaches, including survival analysis, immune response assessment, methylation profiling, and single-cell analysis. Our findings indicate that abnormal FLNC expression correlates with unfavorable prognosis across multiple cancer types, suggesting its potential as a prognostic biomarker. FLNC dysfunction influences the tumor microenvironment, promoting immunosuppressive conditions and disease progression. Methylation profiling reveals a strong correlation between increased methylation, FLNC downregulation, and patient survival, highlighting the role of epigenetic regulation in cancer development. Single-cell analysis uncovers spatial and temporal variations in FLNC expression, identifying distinct cancer cell subsets with unique functional implications. Finally, immunohistochemistry was used to verify the results in different tumors. In conclusion, our research provides insights into the versatile role of FLNC in cancer biology, emphasizing its clinical significance and potential applications as a diagnostic, prognostic, and therapeutic target across diverse cancer types. These findings offer valuable insights for personalized therapeutic interventions and precision medicine approaches.
