Abstract
Dicer siRNA significantly reduced maturation rates increased abnormal spindle and chromosomal organization and reduced the transcripts of Dicer miRNAs spindle formation proteins plk1 and AURKA and spindle check points Bub1 Bublb Depletion of bulb16 markedly prohibited the first polar body extrusion and increased the incidence of misaligned chromosomes and abnormal meiotic spindle assemblyDicer siRNA triggered a cascade reduction for gene expressions starting from Dicer to miRNAs than to spindle assembly proteins and checkpoints which led to abnormal spindle and chromosomal organization Thus Dicer and miRNA appeared to play an important role during oogenesis and were essential for meiotic completion
