Abstract:

 This study aimed to find tissue-specifically expressed miRNAs in ovine adipose tissues.Three small RNA (sRNA) libraries from perirenal,subcutaneous and tail adipose tissues were built for Solexa sequencing.The sequencing results were validated by Stem-loop qRT-PCR technology and further analyzed by bioinformatics methods.The PCR results shown that seven in eight randomly selected miRNAs were consistent with the sequencing results.In perirenal and subcutaneous adipose tissues,128 and 112 conserved miRNAs were obtained,198 and 196 novel miRNAs were found,respectively.Combined with the previous analysis results of miRNAs detected in tail adipose tissue,12 conserved and 66 novel miRNAs were specifically expressed in perirenal adipose tissue;one conserved and 30 novel miRNAs were specifically expressed in subcutaneous adipose tissue;and one conserved and 34 novel miRNAs were specifically expressed in tail adipose tissue.These results provide scientific bases for further research on the regulatory role of miRNA in fat metabolism.
