To survive adverse and ever-changing environmental conditions, an organism must be able to adapt. It has long been established that the cellular reaction to stress includes the upregulation of genes coding for specific stress-responsive factors. In the present study, we demonstrate that during the early steps of the heat stress response, 25% of the Arabidopsis seedling transcriptome is targeted for rapid degradation. Our findings demonstrate that this process is catalyzed from 5' to 3' by the cy ...[more]

Project description:Long interspersed elements 1 (LINE-1 or L1) are retrotransposons that dominate the mouse genomic landscape, and are expressed in Embryonic Stem Cells (ESCs), germ cells, and during early development. Based on clear precedents in plants and fission yeast, we investigated in this study a role for RNAi and other RNA degradation pathways in the regulation of L1 expression and mobilization. We uncovered the existence of novel small (s)RNAs that map to active L1 elements. Some of these sRNAs have characteristics of cognate short-interfering RNA populations, while others display length heterogeneity that evokes a biogenesis through a RNA surveillance pathway, in a Dicer-independent manner. We additionally found that genetic ablation of Dicer and the sRNA effector protein AGO2 has complex and profound consequences on L1 transcription and mobilization in ESCs, indicating that endogenous RNA interference (RNAi) pathway indeed maintain genomic integrity against L1 proliferation. Finally, we investigated the implication of L1 retrotransposition during ESC differentiation and propose that the mobilization of L1 elements in Dicer mutant ESCs could partially explain the inability of these cells to differentiate. 2 samples examined: WT E14 and Dicer mutant mouse ESCs

Project description:Methods: CaMKIIa-creERT2 (Erdmann et al., 2007) and Dicer1f/f (Harfe et al., 2005) were crossed to produce inducible forebrain-restricted Dicer1 knockout mice (Dicer-ifKO) mice. Hippocampal mRNA profiles of 3-month-old wild-type (WT) and (Dicer-ifKO) mice were generated by deep sequencing, in triplicate, using Illumina HiSeq 2500. Each sample included total RNA isolated from the hippocampus of 3 mice. In total, 12 mice per genotype were used. The sequence reads that passed quality filters were mapped to reference genome (GRCm38/mm10) using Bowtie 2 (2.0.5) and TopHat (2.0.6). SAM/BAM files were further processed with Samtools (0.1.18). Read count quantitations were obtained using Seqmonk (0.26.0). Normalization of read counts and differential expression analysis between genotypes was carried out using DESeq2 R package from Bioconductor (Release 2.13). qRT–PCR validation was performed using SYBR Green assays. Results: We mapped about 13-14 million sequence reads per sample to the mouse genome (build GRCm38/mm10) and quantified 76,938 annotated transcripts. DESeq2 R package was used to normalize the counts and perform the differential expression. Differential analysis output was filtered by FDR threshold (padj < 0.1). This approach led us to identify 641 gene isoforms, corresponding to 314 genes that were differentially regulated in the mouse hippocampus upon Dicer ablation. Conclusions: We extend here the characterization of inducible forebrain-restricted Dicer1 mutants confirming the initial memory improvement. Moreover, we describe several novel phenotypes associated with early Dicer loss in the mature brain including an exacerbated response to seizures, increased CA1 neuron excitability, a pronounced weight gain and enhanced induction of immediate early genes (IEGs) in relevant neuronal nuclei. To identify candidate genes that could explain these phenotypes, we conducted two complementary genomic screens for the miRNAs primarily affected and their targets. Overall, our results explain both the initial and late consequences of Dicer loss in excitatory neurons and indicate that Dicer and the miRNA system play a critical role regulating neuronal homeostasis and responsiveness. Hippocampal mRNA profiles of 3-month-old wild-type (WT) and Dicer-ifKO (3 weeks upon tamoxifen administration) male mice were generated by deep sequencing, in triplicate, using Illumina HiSeq 2500. Each sample included total RNA isolated from the hippocampus of 3 mice. In total, 12 mice per genotype were used.

Each sample included total RNA isolated from the hippocampus of 3 mice. In total, 12 mice per genotype were used. After trimming of the adapter sequences and masking for low-complexity or low-quality sequence, the inserts were sorted in separated files according to their lengths. The reads in which no match of the adapter sequences is found were discarded. Inserts of length 18-50 were pooled together and mapped to reference genome (GRCm38/mm10) using Burrows-Wheeler Alignment Tool (BWA) v.0.5.9. We used BWA to map the inserts with a maximum of 2 mismatches. Inserts mapping to several positions on the reference sequences with the same mapping quality were attributed at random to one of the position with a mapping quality of 0. Files were further processed using Samtools v.0.1.18 to get binary files (BAM). Read count quantitations were obtained using Seqmonk (0.26.0). We counted reads that mapped to annotated features (miRNAs, 2035; miscRNA, 491; mRNA 76938; rRNA, 341; snoRNA, 1602; snRNA, 1431; tRNAs, 26248; tRNA, 22). The DESeq2 R package from Bioconductor was used to normalize the counts and perform the differential expression analysis. Results: We mapped about 17-22 million sequence reads per sample to the mouse genome (build GRCm38/mm10) and quantified 109,108 annotated features. DESeq2 R package was used to normalize the counts and perform the differential expression. Differential analysis output was filtered by FDR threshold (padj < 0.1). This approach led us to identify 119 annotated features (including 96 miRNAs) that were differentially regulated in the mouse hippocampus upon Dicer ablation.

Project description:In response to infection, viral genomes are processed by Dicer-like (DCL) ribonuclease proteins into viral small RNAs (vsRNAs) of discrete sizes. vsRNAs are then used as guides for silencing the viral genome. The profile of vsRNAs produced during the infection process has been extensively studied for some group of viruses. However, nothing is known for members of the economically important family Luteoviridae, a group of phloem-restricted viruses. Here, the population of vsRNAs from cotton plants infected with Cotton leafroll dwarf virus (CLRDV), a member of the genus Polerovirus, family Luteoviridae, is characterized.Deep sequencing of small RNAs (sRNAs) from CLRDV-infected cotton leaves was performed. Results showed 21-nt to 24-nt long vsRNAs matching all the viral genome, with a higher frequency of matches in the 3M-CM-"M-BM-^@M-BM-^Y region. Equivalent amounts of sense and antisense vsRNAs were found, and the 22-nt long small RNA class was the most prominent one. Looking for cotton Dcl transcripts levels during infection, we could observe that Dcl4 seems to be up-regulated, while Dcl2 seems to be down-regulated.This is the first report on the profile of sRNAs coming from a plant infected with a member of the family Luteoviridae. Our sequence data strongly suggest that virus-derived double-stranded RNA functions as one of the main precursors of vsRNAsOur results indicate that secondary structures of the viral RNAs are not the main source of the viRNAs observed, as suggested for other viruses. Judging by the profiled size classes, all cotton DCLs might be working to silence the virus. The possible causes for the unexpected high accumulation of 22-nt viRNAvsRNAs are discussed. CLRDV is the causal agent of worldwide cotton pathology named Cotton blue disease. Our results are an important contribution for understanding the molecular mechanisms involved in this and related diseases.

Project description:Bacteria are extremely versatile organisms which rapidly adapt to changing environments. When Escherichia coli cells switch from planktonic growth to biofilm, flagellum formation is turned off, and the production of fimbriae and extracellular polysaccharides is switched on. Here we show that BolA protein is a new bacterial transcription factor which modulates the switch from planktonic to sessile lifestyle. BolA negatively modulates flagella biosynthesis and thus swimming capacity. Furthermore, BolA overexpression favors biofilm formation and involvesinvolving fimbriae-like adhesins and curli production. Our results unraveled for the first time that BolA is a protein with high affinity to DNA, involved in the regulation of several genes of E. coli at a genome-wide scale level. Moreover, this observation further demonstrated that the most significant targets of this protein involved a complex network of genes encoding proteins extremely necessary in biofilm development processes. Herein we propose that BolA is a motile/adhesive transcriptional switch, specifically involved in the transition between the planktonic and the attachment stage of biofilm formation process. In the study presented here DNA enrichment was analyzed in 2 different strains, a strain containing bolA-3xflag-tag and a deletion mutant for this gene, which was used as the control sample.

Project description:DNA replication requires the faithful propagation of both genetic and epigenetic information. There is evidence that DNA polymerases play a role in transcriptional silencing, but the extent of their contribution and how it relates to heterochromatin maintenance is unclear. Analyzing a new hypomorphic pol2a mutant allele, we find that POL2A, the catalytic subunit of the DNA polymerase epsilon, maintains heterochromatin silencing and nuclear organization. We also found that POL2 inhibits DNA methylation and histone H3 lysine 9 methylation, which both correlate with 24-nucleotide small RNA accumulation. In this experiment, we sequenced small-RNA libraries generated from immature inflorescences of pol2a-10 and pol2a-12 mutants and wild-type plants.

Project description:We report that ancestral zinc-finger-domain transcriptional regulators, previously reported to control virulence/symbiosis, implement a cell cycle (SM-bM-^FM-^RG1) transcriptional switch. To unravel how this G1-phase transcriptional program is reinstated during a primitive cell cycle, we first defined G1-specific promoters in the model bacterium Caulobacter crescentus by comparative ChIP-Seq analysis. We then exploited one such promoter as genetic proxy, to identify two conserved developmental regulator paralogs, MucR1/2, that constitute a quadripartite and homeostatic regulatory module directing the switch from SM-bM-^FM-^RG1-phase transcription. Surprisingly, MucR orthologs that regulate virulence and symbiosis gene transcription in Brucella, Agrobacterium or Sinorhizobium support the G1 transcriptional switch in Caulobacter. Pan-genomic ChIP-Seq analyses in Sinorhizobium and Caulobacter show that this module targets orthologous genes. Thus, this ancestral bacterial lineage from which eukaryotic organelles descended may coordinate virulence/symbiosis with other cell cycle functions using a primordial transcription factor fold that is now primarily found in the eukaryotic domain of life.

Project description:Atlantic salmon at their 2nd year in sea were fed with a low, medium or high histidine diet (L, M, and H, respectively) for several months. Samples were taken at three time points, after the first, second and third period, and a number of fishes were assigned to a new feed group following a crossover experimental design. The feeding experiment was carried out in duplicates in cages in sea water. A number of 6 fishes of each nutritional group and from each replicate were sampled at each time point, and weight, length and cataract development were monitored of the sampled fish and an additional number of fishes (18-34). Fish developed cataracts with different severity in response to dietary histidine levels. Lens N-acetylhistidine contents reflected the dietary histidine levels and were negatively correlated to cataract scores. This experiment contains four dietary groups of fish, named LM, HM, LLL and MMM. <br>LM: Low histidine diet in the first period, Medium histidine diet in the second period<br>HM: High first, Medium second period<br>LLL: Low diet in all three periods<br>MMM: Medium diet in all three periods<br>In the analysis LM and HM is compared for early effects, while LLL vs MMM is compared for stable long time effects. Each feeding period is roughly a month each. Each dietary group contains 11 biological replicates. The RNA samples were labelled and hybridised to two channel 16K cGRASP salmonid arrays using a common reference design. The common reference was made from a pool of all samples.
