Step 3: Interactive Visualization

Visualization Plot
  • X-Axis: DNA Methylation (Beta Value)
  • Y-Axis: Gene Expression (log2 normalized)
  • Correlation: Negative correlation implies methylation silences gene expression.

miRNA eQTM Analysis

Explore how methylation at miRNA loci affects the expression of downstream target genes.
