Introduction

GC and SK sent samples to Arraystar, Rockville MD for miRNA analysis. What follows is an attempt to make sense of the results.

outline of pipeline

  • miRNA Expression Profiling
  • Novel miRNA detection
  • Differentially expressed miRNAs
  • miRNA target prediction
  • Pathway Analysis
