miR-34/449 miRNAs are required for motile ciliogenesis by repressing cp110.

Project description:The mir-34/449 family consists of six homologous miRNAs at three genomic loci. Redundancy of miR-34/449 miRNAs and their dominant expression in multiciliated epithelia suggest a functional significance in ciliogenesis. Here we report that mice deficient for all miR-34/449 miRNAs exhibited postnatal mortality, infertility and strong respiratory dysfunction caused by defective mucociliary clearance. In both mouse and Xenopus, miR-34/449-deficient multiciliated cells (MCCs) exhibited a significant decrease in cilia length and number, due to defective basal body maturation and apical docking. The effect of miR-34/449 on ciliogenesis was mediated, at least in part, by post-transcriptional repression of Cp110, a centriolar protein suppressing cilia assembly. Consistent with this, cp110 knockdown in miR-34/449-deficient MCCs restored ciliogenesis by rescuing basal body maturation and docking. Altogether, our findings elucidate conserved cellular and molecular mechanisms through which miR-34/449 regulate motile ciliogenesis.

Identification of FOXJ1 effectors during ciliogenesis in the fetal respiratory epithelium and embryonic left-right organizer of the mouse - IMCD3 screen

Project description:Formation of motile cilia in vertebrate embryos is essential for proper development and tissue function. Key regulators of motile ciliogenesis are the transcription factors FOXJ1 and NOTO, which are conserved throughout vertebrates. Downstream target genes of FOXJ1 have been identified in a variety of species, organs and cultured cell lines; in murine embryonic and foetal tissues, however, FOXJ1 and NOTO effectors have not been comprehensively analysed and our knowledge of the downstream genetic programme driving motile ciliogenesis in the mammalian lung and ventral node is fragmentary. We compared genome-wide expression profiles of undifferentiated E14.5 vs. abundantly ciliated E18.5 micro-dissected airway epithelia as well as Foxj1+ vs. Foxj1-deficient foetal (E16.5) lungs of the mouse using microarray hybridisation. 326 genes deregulated in both screens are candidates for FOXJ1-dependent, ciliogenesis-associated factors at the endogenous onset of motile ciliogenesis in the lung, including 123 genes that have not been linked to ciliogenesis before; 46% of these novel factors lack known homologues outside mammals. Microarray screening of Noto+ vs. Noto null early headfold embryos (E7.75) identified 59 of the lung candidates as NOTO/FOXJ1-dependent factors in the embryonic left-right organiser that carries a different subtype of motile cilia. For several uncharacterised factors from this small overlap – including 1700012B09Rik, 1700026L06Rik and Fam183b – we provide extended experimental evidence for a ciliary function.
