Animal development fundamentally relies on the precise control, in space and time, of genome expression. Whereas we have a wealth of information about spatial patterning, the mechanisms underlying temporal control remain poorly understood. Here we show that Pri peptides, encoded by small open reading frames, are direct mediators of the steroid hormone ecdysone for the timing of developmental programs in Drosophila. We identify a previously uncharacterized enzyme of ecdysone biosynthesis, GstE14, and find that ecdysone triggers pri expression to define the onset of epidermal trichome development, through post-translational control of the Shavenbaby transcription factor. We show that manipulating pri expression is sufficient to either put on hold or induce premature differentiation of trichomes. Furthermore, we find that ecdysone-dependent regulation of pri is not restricted to epidermis and occurs over various tissues and times. Together, these findings provide a molecular framework to explain how systemic hormonal control coordinates specific programs of differentiation with developmental timing. - Yuji Kageyama, Takefumi Kondo, Yoshiko HashimotoBIOCHIMIE 93 11 1981 - 1986 2011年11月 [査読有り][通常論文]
Genome analysis has identified a number of putative non-protein-coding transcripts that do not contain ORFs longer than 100 codons. Although evidence strongly suggests that non-coding RNAs are important in a variety of biological phenomena, the discovery of small peptide-coding mRNAs confirms that some transcripts that have been assumed to be non-coding actually have coding potential. Their abundance and importance in biological phenomena makes the sorting of non-coding RNAs from small peptide-coding mRNAs a key issue in functional genomics. However, validating the coding potential of small peptide-coding RNAs is complicated, because their ORF sequences are usually too short for computational analysis. In this review, we discuss computational and experimental methods for validating the translatability of these non-coding RNAs. (C) 2011 Elsevier Masson SAS. All rights reserved. - T. Kondo, S.

A substantial proportion of eukaryotic transcripts are considered to be noncoding RNAs because they contain only short open reading frames (sORFs). Recent findings suggest, however, that some sORFs encode small bioactive peptides. Here, we show that peptides of 11 to 32 amino acids encoded by the polished rice (pri) sORF gene control epidermal differentiation in Drosophila by modifying the transcription factor Shavenbaby (Svb). Pri peptides trigger the amino-terminal truncation of the Svb protein, which converts Svb from a repressor to an activator. Our results demonstrate that during Drosophila embryogenesis, Pri sORF peptides provide a strict temporal control to the transcriptional program of epidermal morphogenesis. - Yoshiko Hashimoto, Takefumi Kondo, Yuji KageyamaDEVELOPMENT GROWTH & DIFFERENTIATION 50 Suppl 1 S269 - S276 2008年06月 [査読有り][通常論文]
Generally, bioactive small peptides are derived from precursors with signal sequences at their N-terminal ends, which undergo modification and proteolysis through a secretory pathway. By contrast, small peptides encoded in short open reading frames (sORF) lack signaling sequences and therefore are released into the cytoplasm, which may result in their having functions distinct from those of secreted peptides. Several small peptides encoded by sORF are involved in the morphogenesis of multicellular organisms. POLARIS, ROTUNDIFOLIA4, and Enod40 are plant peptides that are involved, respectively, in root formation, leaf shape control, and cortical cell division during nodule formation. Brick1/HSPC300 is an evolutionarily conserved component of the actin reorganization complex. polished rice/tarsal-less and mille-pattes encode related small peptides that are required for epithelial morphogenesis in Drosophila and segmentation in Tribolium. There are only a few known examples of small peptides encoded by sORF, and their molecular functions are still largely obscure. Nevertheless, an increasing number of sORF genes is being identified, and further research should reveal their roles in novel molecular mechanisms underlying developmental events. - Takefumi Kondo, Yoshiko Hashimoto, Kagayaki Kato, Sachi Inagaki, Shigeo Hayashi, Yuji KageyamaNATURE CELL BIOLOGY 9 6 660 - U87 2007年06月 [査読有り][通常論文]
Transcriptome analyses in eukaryotes, including mice and humans, have identified polyA- containing transcripts that lack long open reading frames (ORFs; > 100 amino acids) 1,2. These transcripts are believed most likely to function as non-coding RNAs, but their translational capacities and biological activities have not been characterized in detail. Here, we report that polished rice (pri), which was previously identified as a gene for a non-coding RNA in Drosophila3,4, is in fact transcribed into a polycistronic mRNA that contains evolutionarily conserved short ORFs that encode 11 or 32 amino acid-long peptides. pri was expressed in all epithelial tissues during embryogenesis. The loss of pri function completely eliminated apical cuticular structures, including the epidermal denticles and tracheal taenidia, and also caused defective tracheal-tube expansion. We found that pri is essential for the formation of specific F-actin bundles that prefigures the formation of the denticles and taenidium. We provide evidences that pri acts non-cell autonomously and that four of the conserved pri ORFs are functionally redundant. These results demonstrate that pri has essential roles in epithelial morphogenesis by regulating F-actin organization. - Y Hashimoto, H Suzuki, Y Kageyama, K Yasuda, K InoueGENE EXPRESSION PATTERNS 6 2 201 - 205 2006年01月 [査読有り][通常論文]
Maternally supplied germ plasm is essential for germ lineage establishment in many species, but the molecular details are still largely unknown, especially in vertebrates, and identification of novel factors that localize to germ plasm is desirable. We previously reported that one of the components of zebrafish germ plasm is mRNA of the bruno-like (brul) gene, a homologue of bruno, which, in Drosophila, is known to participate in germ lineage establishment. Here, we show that not only mRNA but also protein of brul is localized to the zebrafish germ plasm at the ends of the cleavage furrows. In 4- and 8-cell stage embryos, Brul protein is localized to the periphery of the blastomeres, as well as to the ends of the cleavage furrows, forming numerous minute particles. These particles appear at the cortex of the fertilized egg within 10 min after fertilization. Surprisingly, these distinctive localizations, as well as the minute particles, completely disappeared by the 16-cell stage, although relatively weak expression was detected ubiquitously throughout embryogenesis. This is the first report of a protein that localizes to the germ plasm in zebrafish. (C) 2005 Elsevier B.V.

Maternally supplied factors in fertilized eggs play essential roles in the establishment of primordial germ cells. In zebrafish, cytoplasm at the distal ends of the first and second cleavage furrows has been assumed to contain germ lineage determinants, since maternal transcripts of genri lineage-specific genes are localized to ends of the cleavage furrows. To investigate whether these parts of cytoplasm are required for germ cell formation, we removed all four regions of the cytoplasm by glass capillary at the 4-cell stage. Histological analysis revealed that the ablation of cytoplasm at the ends of the cleavage planes resulted in a severe reduction in the number of germ cells. In addition, the expression of germ lineage markers was eliminated by cytoplasmic ablation. These results demonstrated that cytoplasm at the distal ends of cleavage furrows is essential for germ cell formation. We also found novel localization patterns for zDazl and brul mRNAs along the cleavage planes. Our findings provide the first direct evidence that localized cytoplasmic factors are indispensable for germ cell establishment in zebrafish. (C) 2004 Elsevier Inc. All rights reserved.
