Area of Science:

  • Oncology
  • Molecular Biology
  • Genomics

Background:

  • Tumor DNA is static, while RNA profiles reflect dynamic tumor behavior and characteristics.
  • Messenger RNA (mRNA) and long non-coding RNA (lncRNA) are key RNA types studied in prostate cancer.
  • RNA biomarkers assess tumor aggressiveness and predict treatment sensitivity.

Purpose of the Study:

  • To review RNA types, gene expression technologies, and available signatures for prostate cancer.
  • To highlight the role of RNA profiles in understanding tumor behavior and treatment response.
  • To discuss the development and clinical application of RNA-based biomarkers.

Main Methods:

  • Review of existing literature on RNA types and their roles in prostate cancer.
  • Discussion of microarray and RNA sequencing (RNAseq) for transcriptomic analysis.
  • Analysis of gene expression signatures for prognostic and predictive applications.

Main Results:

  • Over 30 prognostic gene expression signatures have been developed for prostate cancer.
  • Three prognostic signatures are commercially available and used in clinical trials.
  • Transcriptomic analysis enables discovery of predictive signatures for treatment sensitivity/resistance.

Conclusions:

  • RNA profiles provide crucial insights into tumor behavior and clinical outcomes.
  • Gene expression signatures are valuable tools for prostate cancer prognostics and treatment selection.
  • Advancements in RNA analysis technologies are expanding biomarker discovery and clinical utility.
