Summary

This summary is machine-generated.

Cyclin-dependent kinase 1 (CDK1) is overexpressed in most cancers and linked to poor prognosis. High CDK1 expression correlates with tumor mutational burden, immune cell infiltration, and poorer survival, suggesting its potential as a prognostic biomarker and immunotherapy target.

Area Of Science

  • Oncology
  • Immunology
  • Molecular Biology

Background

  • Cyclin-dependent kinase 1 (CDK1) is crucial for cell cycle regulation.
  • Elevated CDK1 expression is frequently observed in various tumors and associated with adverse clinical outcomes.
  • Understanding CDK1's role in pan-cancer is vital for developing targeted therapies.

Purpose Of The Study

  • To evaluate the prognostic significance of CDK1 across multiple cancer types.
  • To investigate the relationship between CDK1 expression and tumor immune microenvironment.
  • To explore CDK1's association with tumor mutational burden and microsatellite instability.

Main Methods

  • Bioinformatic analysis of CDK1 expression and survival data from pan-cancer databases.
  • Assessment of immune cell infiltration using ESTIMATE and CIBERSORT algorithms.
  • Correlation analysis of CDK1 with tumor mutational burden (TMB), microsatellite instability (MSI), and immune-related genes.

Main Results

  • CDK1 is overexpressed in most tumors, particularly gastrointestinal cancers, and linked to poor survival in several types (e.g., KIRP, LIHC, LUAD, PAAD, PRAD, SARC).
  • CDK1 expression correlates with TMB in 22 cancers and MSI in 8 cancers, notably in UCEC, STAD, SARC, READ, MESO, HNSC, and COAD.
  • CDK1 levels are associated with infiltrating immune cells (macrophages, T cells, B cells) and show significant co-expression with 47 immune-related and immune checkpoint genes.

Conclusions

  • CDK1 plays a significant role in cancer development and metastasis across various tumor types.
  • CDK1 serves as a potential prognostic biomarker for patient outcomes.
  • CDK1 represents a promising therapeutic target for cancer immunotherapy.
