categorization of miRNA and miRNA star

Question

[Sam]

Hi all

I handled some smallRNA-seq libraries which obtained from lukemic samples but after differential expression analysis I have some 3p and 5p miRNAs with very similar expression profile and in some case 3p and 5p miRNAs shows contrary expression compare to miRbase reads. For instance :

              mean reads

  mir-139-3p    75.56
  mir-139-5p    44.13

but in mirgenedb mir-139-3p reported as star mir , so how I should categorized these miRNAs as miRNA/miRNAstar ?
