Comparative profiling of microRNA transcriptome in different developmental phases and analysis of microRNAs associated with reproductive development in the Brown Planthopper, Nilaparvata lugens

ABSTRACT: In the present study, small RNA libraries derived from three developmental phases (1st day after eclosion, 3rd day after eclosion and 5th day after eclosion) of short-winged morphs female adults were constructed and sequenced. A total of 15,571,298, 16,362,568 and 15,147,276 raw reads were obtained from three BPH small RNA libraries, respectively. Moreover, we identified 905 miRNAs, including 263 conserved (belonging to 37 families) and 642 novel miRNAs. In addition, the expression profiles of these miRNAs were assessed across different developmental stages Specifically, 22, 19, and 12 miRNAs were differentially expressed between3d and 1d, 5d and 1d, and 5d and 3d, respectively. A total of 43 miRNAs were differentially expressed in the three developmental phases, and 7 miRNAs were validated using quantitative RT-PCR. Target Scan and miRanda predicted14568 putative targets for 43 differentially expressed miRNAs within the 3’UTRs sequences of BPH transcriptome. Moreover, GO and KEGG pathway analysis of the predicted miRNA targets further illustrate the likely roles for these differentially expressed miRNAs in reproduction.

MicroRNA expression profiles in pigeon(Columba livia) skeletal muscle satellite cells during differentiation

Project description:A comparative profile of miRNAs in pre- and post-differentiated pigeon SMSCs (SMSC-1d and SMSC-5d) was performed by using high-throughput sequencing. We identified known porcine miRNAs, novel miRNAs, and miRNAs that are conserved in other birds and mammals. Our findings demonstrated that miRNAs are extensively involved in the differentiation of SMSCs in pigeons, and provide a valuable resource for the pigeon breeding.

Identification and analysis of brown planthopper-responsive microRNAs in the resistant and susceptible rice plants

Project description:MicroRNAs (miRNAs) regulate a spectrum of development and defense response processes in plants. The brown planthopper (BPH) is the most devastating insect pest of rice, BPH resistance gene BPH15 has a strong resistance to BPH. In this study, we analyzed six miRNA profiles of BPH15 introgression line (P15) and susceptible recipient line (PC) in 3 time points (0h, 6h and 48h) after BPH attacked, and identified 464 known miRNAs and 183 novel miRNAs. Before BPH feeding we identified 23 miRNAs expressed differently in P15 and PC. Then after BPH feeding, 104 miRNAs were found expressed differently in P15, and 80 miRNAs were found expressed differently in PC. Among them, miR167, miR444d, miR1846e, miR3979-3p, miR531 were found to be involved in BPH stress response. The response to BPH of P15 was much wider and more rapidly than PC. The levels of a subset of miRNAs were confirmed by qRT-PCR. The targets of miRNAs were predicted and validated by gene expression profiling. Additionally, the target genes of 2 differently expressed miRNAs (miR160f-5p and miR167a-5p) were confirmed by detecting YFP fluorescence and western blotting. Our data provide an important basis for evaluating the role of miRNA in the regulation of BPH interactions in rice.

Expression data from brown planthhoper (BPH) infested and non-infested rice

Project description:KMD is genetically engenered to be highly resistant to lepidopteran pests through expressing a synthetic cry1Ab gene and its parent non-transgenic rice is Xiushui 11.The developmental duration of BPH feeding on KMD2 was significantly delayed. And moreover, the fecundity of BPH was significantly lower when fed on Bt rice than on the non-Bt parental plants.To investigate unintended effects in KMD2 that causes changes in BPH performance, we performed microarray (GeneChip) analysis to compare the gene expression profiles between Bt rice and non-transgenic parental plants in response to BPH infestation. We used microarrays to detect Bt-independent variation, which might render Bt rice more defensive or less nutritious to BPH. For BPH treatment, 10 second-instar nymphs were infested onto each 30-day-old seedling. After 72 h, the BPH nymphs were carefully removed and rice shoots of both BPH-infested and non-infested plants were sampled for microarray analysis. There were four treatments: Xiushui 11-non infested, Xiushui 11-BPH infested, KMD2-non infested, KMD2-BPH infested, three biological replications.

Identification of microRNAs differentially expressed in prostatic secretions of patients with prostate cancer

Project description:In this study, we aimed to identify a miRNA expression signature that could be used to distinguish PCa from BPH. We have shown for the first time in the literature the presence of miRNAs in the PSS. We suggest PSS as a powerful non-invasive source for evaluation of prognosis in PCa, since prostate massages can be easily applied during routine examination. Our results showed that certain differentially expressed miRNAs in PSS could be used as diagnostics markers. Prostate secretion samples (PSS) from 23 PCa and 25 benign prostate hyperplasia (BPH) patients were obtained from Urology Department of Bagcilar Educational and Research Hospital (Istanbul). MicroRNA (miRNA) profiling of eight PSS (four from BPH, four from PCa patients) were performed using microarray. Four of significantly deregulated miRNAs were further confirmed using quantitative reverse-transcription PCR (qRT-PCR). Statistical analysis was performed using Student’s t-test. ROC curves were plotted with SPSS-15.0.

A combined small RNA and transcriptome sequencing analysis illuminates the response of resistance to brown planthopper in rice [miRNA-seq]

Project description:Here, a combined small RNA and transcriptome sequencing analysis was performed on the BPH6-transgenic and Nipponbare plants sheath samples at the different feeding stage by BPH, and differentially expressed microRNAs (DEMs) and genes (DEGs) were identified and further analyzed for a possible involvement in BPH6 mediated resistance mechanism. A total of 217 DEMs and 7,874 DEGs were identified in the BPH6-transgenic and Nipponbare plants after BPH feeding. At the miRNA level, 29 miRNAs, including the members of miR160, miR166, miR169, miR1861, miR319 and miR390 family and other miRNAs, appeared opposite expression at early or late feeding stages between the two varieties, and 9 miRNAs specially expressed in the BPH6-transgenic plans, suggesting these miRNAs might play an important role in BPH6-mediated resistance to BPH. For the transcriptome, 949 DEGs appeared opposite expression at early or late feeding stages of two rice genotypes were identified and enriched in metabolic process, cellular development, cell wall organization, cellular component movement and hormone transport, and in involved in certain kinds of primary and secondary metabolite synthesis by GO and KEGG enrichment analysis. 24 genes were further selected to be considered as BPH resistance related gene candidates. Finally, integrated analysis of DEMs and DEGs showed that 34 miRNAs corresponding to 42 target genes were selected as BPH resistance related miRNA-mRNA interaction candidates.
