Title	Phosphoproteomic analysis of liver of Dicer knockout mice
Description	Dicer is an essential ribonuclease involved in the biogenesis of miRNA. Previous studies have reported that Dicer is dysregulated in multiple types of cancers. To investigate the downstream phosphoproteome of Dicer, we carried out phosphotyrosine profiling of the liver of Dicer knockout of mice. We employed antibody-based enrichment of phosphotyrosine containing peptides coupled with spike-in SILAC-based quantitation. Over 400 phosphoisites were identified in each condition while 290 phosphosites were quantitated in common. Amongst these, several key signaling molecules like receptor tyrosine kinase MET, MET, PDGFR, EPHA2, EPHB4 and IGF1R/INSR were hyperphosphorylated. Also, non-receptor tyrosine kinases of Src family and their downstream effector signaling partners including IRS2 and STAT3were found to be hyperphosphorylated. Our study indicates that there is significant alteration in the signaling pathways upon ablation of Dicer.
