miRNA expression profiling of kidney collecting duct from mice lacking Dicer1 in AQP2 expressing cells.

To investigate the role of miRNAs in the principal cell of kidney collecting duct, a Cre-LoxP recombination strategy was used to generate a mouse model lacking the endoribonuclease Dicer in AQP2 expressing cells (DicerAQP2Cre+). To identify miRNAs altered in DicerAQP2Cre+ mice, small RNA-sequencing analysis was performed on inner medulla tissue from 1-month-old DicerAQP2Cre+ mice and controls (n=3+3 mice). Small RNA-sequencing was used as, relative to probe-based microarrays or RT-qPCR plate arrays, this approach allows both the identification of miRNAs when they have been differentially processed and it offers the possibility to identify novel miRNAs. Overall design: miRNA expression profiles of 1-month-old DicerAQP2Cre+ mice and controls (n=3+3 mice).
