Profile of small RNA transcriptome during cortical development in the Rat

ABSTRACT: Small non-coding RNAs play important roles in regulating gene expression during development and disease. However, a comprehensive analysis of small RNAs in developing brain is largely lacking. By using next-generation sequencing technique, we carried out a systematic analysis of small RNA transcriptome of rat neocortex from early developmental stage till adult. Our results revealed an extraordinary degree of stage-specific profiling of miRNA, and other classes of small RNAs including snoRNA, rasRNA, scRNA and unexpectedly piRNA, which was considered to be solely expressed in germline tissues. Developmentally regulated miRNA editing was also observed. This study further showed the effectiveness of the high through-put sequencing in genome-wide analysis of small RNAs. The dataset described here will greatly contribute to our understanding of the divergence, variation, and function of small RNAs and may be a valuable resource in clarifying new regulatory mechanisms of cortical development.

<h4>Background</h4>The morphogenesis of the cerebral cortex depends on the precise control of gene expression during development. Small non-coding RNAs, including microRNAs and other groups of small RNAs, play profound roles in various physiological and pathological processes via their regulation of gene expression. A systematic analysis of the expression profile of small non-coding RNAs in developing cortical tissues is important for clarifying the gene regulation networks mediating key develop ...[more]

Project description:MicroRNA (miRNA) is a class of functional non-coding small RNA with 19-25 nucleotides in length. Amur grape (Vitis amurensis Rupr.) is an important wild fruit crop with the strongest cold resistance in the Vitis genus and is used as an excellent breeding parent for grapevine, and with growing interest in terms of wine production. To date, there is a relatively large number of grapevine miRNAs (vv-miRNAs) from cultivated grapevine varieties such as Vitis vinifera L. and hybrids of V. vinifera and V. labrusca, but there is no report on miRNAs from Vitis amurensis Rupr, a wild grapevine species. In this study, a small RNA library from Amur grapes was constructed and Solexa technology used to perform deep sequencing of the library followed by subsequent bioinformatics analysis to identify new miRNAs. In total, 126 conserved miRNA belonging to 27 miRNA families were identified, and 34 known but non-conserved miRNAs were also found. Significantly, 72 new potential Amur grapevine-specific miRNAs were discovered. The sequences of these new potential va-miRNAs were further validated through miR-RACE, accumulation of 18 new va-miRNAs in seven tissues of grapevines were also confirmed by real time RT-PCR (qRT-PCR) analysis, and expression levels of va-miRNAs in flowers and berries were basically consistent in identity to those from deep sequenced sRNAs libraries of independent corresponding tissues. We also describe the conservation and variation of va-miRNAs using miR-SNPs and miR-LDs during plant evolution based on comparison of orthologous sequences, and revealed the number and sites of miR-SNP of diverse miRNA families exhibited distinct divergence. Finally, 346 target genes for the new miRNAs were predicted and they include a number of Amur grapevine stress tolerance genes and many genes regulating anthocyanin systhesis and sugar metabolism. Deep sequencing of short RNAs from Amur grapes flowers and fruits identified 72 new potential miRNAs and 34 known but non-conserved miRNAs, indicating that specific miRNAs exist in Amur grapes. These results show that a number of regulatory miRNAs exist in Amur grapes and play an important role in Amur grape growth, development, and response to abiotic or biotic stress. High throughput sequencing was employed to identify miRNAs in Amur grapevine and try to describe their functions in Amur grapevine growth and development.

Project description:Honeybees are very important eusocial insects and are involved in the pollination of many plants. Queen bees and worker bees develop from the same fertilized eggs, and are thus genetically identical despite their substantial behavioural and physiological differences. The mechanism governing developmental differences between worker and queen bees has always attracted much interest. While there are several reports on mRNA expression related to caste differentiation, no systematic investigation of small RNAs has thus far been carried out. Results: Using deep sequencing we systematically profiled small RNA expression in 4th-6th day worker larvae and queen larvae (the critical stages at which the fates of workers and queens are determined), and found that 38 miRNAs were differentially expressed between worker and queen larvae. In addition, 639 mature miRNA candidates were identified in our work for the first time, of which, 526 were expressed only in workers (318) or queens (208). Conclusion: We present the first profile of honeybee small RNAs and explore the mechanism of caste differentiation between worker and queen bees. Caste-specific expression patterns and large discrepancies in small RNA profiles between worker and queen bees indicate that small RNAs may be related to the differential development of worker and queen bee larvae. Results presented here will make a valuable contribution to understanding the caste switch between worker and queen bees. Three healthy 10-frame colonies of ‘Zhenongda No.1’- a high-yielding royal jelly breed of Apis mellifera ligustica , were maintained at the Huajiachi campus of Zhejiang University. In each colony, the queen laid eggs over a period of 24 hours in one empty frame which was subsequently moved to an egg-free super-chamber. After 66 hours (less than 18 hours after hatching), we transferred 150 larvae into queen cups to rear queens in each colony and put the queen cup frames into their corresponding colonies. 40-60 worker larvae and queen larvae were collected from each colony after 4 days (73~90 h after hatching), 5 days (97~114 h after hatching) and 6 days (121~138 h after hatching). The larval samples were collected into 50 ml tubes, immediately frozen in liquid nitrogen and stored at -80C until being used for RNA extraction. After total RNA was extracted and quantified , relative equal amounts of total RNAs from each of the three sampling days were pooled into respectively worker and queen samples, and the fraction of small RNAs less than 30nt long was retained and sequenced on the Illumina/Solexa high-throughput platform (HTP).

Project description:In plants, MicroRNAs (miRNAs) are a new class of endogenous small RNAs that play essential regulatory roles in plant growth, development and stress response. Extensive studies of miRNAs have been performed in model plants such as rice, Arabidopsis thaliana and other plants. However, the number of miRNAs discovered in maize is relatively low and little is known about miRNAs involved in the four stages during maize ear development. Here, we use deep-sequencing, miRNA microarray assays and computational methods to identify, proM-oM-,M-^Ale, and describe conserved and non-conserved miRNAs at four developmental stages. A total of 27 conserved miRNA families were identiM-oM-,M-^Aed in all four stages, In addition to known miRNAs, we also found 23 new maize-specific miRNAs together with their star strands. We have also shown that almost all of them originated from single genes. We have found that many known and new miRNAs showed temporally expression. Finally, a total of 251 transcripts (140 genes) targeted by 102 small RNAs including 98 miRNAs and 4 ta-siRNAs were identified by genomic-scale high-throughput sequencing of miRNA cleaved mRNAs.This study led to the confirmation of the authenticity of 27 conserved miRNA families and the discovery of 23 novel miRNAs in maize. In addition, we have identified 130 targets of known and new miRNAs and ta-siRNA using recently developed tools for the global identification of miRNA targets. Identification and characterization of this important class of regulatory genes in maize may improve our understanding of molecular mechanism controlling flower development. The seeds of maize inbred line B73 were first sterilized and germinated in an incubator, then grown in a controlled environment with 28M-BM-0C/21M-BM-0C (day/night) under a 16-h day/8-h night photoperiod with a relative humidity of 70%. Ear development can be divided into four stages: the growth point elongation phase, spikelet differentiation phase, the floret primordium differentiation phase and floret organ differentiation phase. Plant materials (ears) were collected as described previously. In brief, ears were manually collected at the four developmental stages according to the plant features (number of visible leaves, leaf age index, and number of unfolded and folded leaves) combined with microscopic observation.
