This study introduces a novel multischeme system for cancer research, using gene expression data and clinical knowledge. It employs unsupervised clustering and supervised classification for accurate cancer diagnosis and prognosis.

Area of Science:

  • Bioinformatics
  • Genomics
  • Computational Biology

Background:

  • Traditional single-gene studies like reverse transcriptase-polymerase chain reaction (RT-PCR) are limited for high-throughput gene expression analysis.
  • Microarray technology generates vast gene expression datasets, posing challenges for cancer research, particularly in identifying diagnostic and prognostic biomarkers.
  • Analyzing large gene expression datasets with small patient cohorts is a significant hurdle in precision cancer medicine.

Purpose of the Study:

  • To develop a novel multischeme system for analyzing gene expression data in cancer research.
  • To identify signature genes (biomarkers) for precise cancer diagnosis, treatment, and prognosis.
  • To establish a foundation for future drug target discovery through advanced data analysis.

Main Methods:
