text: Yo, check it, let me break it down for ya,
  RNA interference, RNAi, that's the game,
  MicroRNA, miRNA, regulating genes, it's the same,
  Evolutionary mechanism, conserved in every eukaryote,
  Posttranscriptional control, that's how it goes, no joke.
  
  Drosha, the key player, in miRNA's maturation,
  In this study, we dive into shrimp's situation,
  Marsupenaeus japonicus, that's the name,
  Analyzing Drosha, shedding light on the game.
  
  The gene encodes a peptide, 1081 amino acids strong,
  Two ribonuclease III C terminal domains, that's where it belongs,
  Double-stranded RNA binding motif, it's got the groove,
  Homologous to other animals, that's the move.
  
  Quantitative RT-PCR, we got the analysis,
  Drosha highly expressed in the lymphoid organ, no fallacy,
  When faced with WSSV, it's up-regulated, you see,
  Drosha's in the antiviral immunity, that's the key.
  
  Knocking down Drosha, miRNA maturation's gone,
  Resulting in higher virus loads, shrimp can't carry on,
  Our study reveals, Drosha's role is clear,
  In shrimp's antiviral defense, it's the pioneer.
