Gene expression data from Melan-a cells expressing reduced level of Dicer and control Melan-a cells [24 hours]

Project description:To investigate the molecular mechanism of the hypopigmentation observed in Dicer KO mice, Dicer knockdown was realised in vitro in normal C57BL/6 mouse melanocyte Melan-a cells. Transient transfection of Melan-a cells with siRNA directed against Dicer reduced Dicer protein levels to approximately 40% of that of siScr Melan-a cells 24 hours after transfection. We analyzed the transcriptome of Melan-a cells 24 hours after transfection with siDicer or siScr to understand the molecular mechanisms involved in Dicer-dependent melanocyte migration.

microRNA levels data from Melan-a cells expressing reduced level of Dicer and control Melan-a cells

Project description:To investigate the molecular mechanism of the hypopigmentation observed in Dicer KO mice, Dicer knockdown was realised in vitro in normal C57BL/6 mouse melanocyte Melan-a cells. Transient transfection of Melan-a cells with siRNA directed against Dicer reduced Dicer protein levels to approximately 40% of that of siScr Melan-a cells 24 hours after transfection. We analyzed the miRnome of Melan-a cells 24 and 48 hours after transfection with siDicer or siScr to understand the molecular mechanisms involved in Dicer-dependent melanocyte migration.

DICER-interacting partners in juvenile mouse testes

Project description:DICER has a well-characterized role in the processing of microRNAs (miRNAs) and small interfering RNAs (siRNA) that are important for post-transcriptional gene regulation. Emerging evidence suggests that DICER also has several non-canonical functions beyond miRNA/siRNA biogenesis, for example in transcriptional gene silencing at the chromatin level, as well as in RNA degradation and maintenance of genomic integrity. We have shown that the function of DICER in germ cells is essential for normal spermatogenesis; male mice lacking DICER in postnatal male germ cells are infertile due to severe defects in haploid differentiation. To better understand the function of DICER in male germ cells, we immunoprecipitated DICER from juvenile mouse testes and performed mass spectrometric analysis to identify DICER-interacting proteins.

Phosphoproteomic analysis of liver of Dicer knockout mice

Project 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.

mRNA expression analysis of undifferentiated Dicer -/- (27H10) embryonic stem cells after miRNA transfection

Project description:We have analyzed the transcript expression levels in Dicer knock-out embryonic stem (ES) cells 24 hours after transfection with either control siRNA agains Renilla luciferase or miRNA Mimics (Dharmacon) of mmu-miR-290 cluster members in order to identify primary targets of miR-290 cluster miRNAs. Keywords: Comparison of effect of two different transfections on transcriptome of Dicer-KO ES cells
