Project description:Purpose: Recombinant human erythropoietin administration studies involving “omics” approaches have demonstrated a gene-expression signature that could aid detection of blood doping. However, current anti-doping testing does not involve blood collection into tubes with RNA preservative. This study investigated if whole blood in long-term storage could be used for transcriptomic analysis despite lacking RNA preservation. Methods: Whole blood samples were collected from thirteen male healthy individuals. Long-term storage: whole blood collected into Tempus™ tubes and K2EDTA tubes and subjected to long-term (i.e., −80°C) storage and RNA extracted. After storage, Tempus and K2EDTA tubes were thawed and extracted using Tempus™ Spin RNA Isolation Kit (Life Technologies, Carlsbad, CA, USA). Samples from seven subjects that presented higher RIN value (≥7) were selected for RNA_Seq analysis. Results: The experiment provided RNA quality and purity for gene expression analysis. Total of 19239 genes were mapped and the gene expression analysis showed that 658 genes were differentially expressed (which means 3.4% of mapped genes). With 269 being up-regulated and 389 down-regulated. None of the transcripts described in previous studies as biomarkers for blood doping (Durussel et al. 2016; Wang, Durussel, et al. 2017) were differently expressed. Conclusion: RNA quantity, purity and integrity was not significantly compromised from long-term storage in blood storage tubes lacking RNA stabilisation, indicating that transcriptomic/omics analysis could be conducted using anti-doping samples collected or biobanked without RNA preservation.

Project description:Recombinant human erythropoietin administration studies involving transcriptomic approaches have demonstrated a gene-expression signature that could aid detection of blood doping. However, current anti-doping testing does not involve blood collection into tubes with RNA preservative. This study investigated if whole blood in long-term storage and whole blood leftover from standard haematological testing in short-term storage could be used for transcriptomic analysis despite lacking RNA preservative. Whole blood samples were collected from thirteen and fourteen healthy males, for long-term and short-term storage experiments. Long-term storage: whole blood collected into Tempus™ tubes and K2EDTA tubes and subjected to long-term (i.e., −80°C) storage and RNA extracted. After storage, K2EDTA tubes were thawed and extracted using GeneJET RNA Purification Kit (Thermo Fisher Scientific, Vilnius, Lithuania) or Tempus™ Spin RNA Isolation Kit (Life Technologies, Carlsbad, CA, USA). RNA quality and purity was sufficient for gene expression analysis. Principle Component Analysis of microarray and RNA-seq gene expression data for long-term storage: When comparing gene expression between blood tubes with and without RNA preservation, 6% (4058 transcripts) were differentially expressed. RNA quantity, purity and integrity was not significantly compromised from long-term storage in blood storage tubes lacking RNA preservative, indicating that transcriptomic analysis could be conducted using anti-doping samples collected or biobanked without RNA preservation.

Project description:Purpose: Recombinant human erythropoietin administration studies involving “omics” approaches have demonstrated a gene-expression signature that could aid detection of blood doping. However, current anti-doping testing does not involve blood collection into tubes with RNA preservative. This study investigated if whole blood in short-term storage could be used for transcriptomic analysis despite lacking RNA preservation. Methods: Whole blood samples were collected from fourteen male healthy individuals. Short-term storage: whole blood collected into K2EDTA tubes and subjected to short-term (i.e., at 4°C) storage for 6 hours, 12 hours, 24 hours and 48 hours. After storage, blood from K2EDTA tubes were transferred into Tempus™ Blood tubes, and then extracted using Tempus™ Spin RNA Isolation Kit (Life Technologies, Carlsbad, CA, USA). Samples from four subjects of each time point that presented higher RIN value (≥7) were selected for RNA_Seq analysis. Results: The experiment provided RNA quality and purity for gene expression analysis. Considering 6-hours storage as a reference group, the number of differentially expressed genes were 19, 45 and 70 in comparison to 12, 24 and 48-hours, respectively (which means 0.37, 0.88 and 1.37% of mapped genes). Of the 19 differentially expressed genes in the comparison 6 vs. 12-hours, 9 overlapped with the 45 in the comparison 12 vs. 24-hours. Furthermore, 40 of those 45 overlapped with the 70 differentially expressed in the comparison 6 vs. 48-hours. None of the transcripts described in previous studies (Durussel et al. 2016; Wang, Durussel, et al. 2017) were differently expressed. Conclusion: RNA quantity, purity and integrity was not significantly compromised from short-term storage in blood storage tubes lacking RNA stabilisation, indicating that transcriptomic/omics analysis could be conducted using anti-doping samples collected without RNA preservation.

Project description:Seed aging is a complex biological process attracting the scientists’ attention for many years. High-throughput small RNA sequencing was applied to examine microRNAs contribution in barley seeds senescence. Unique samples of seeds that despite the same genetic makeup differed in viability after over 45 years of storage in a dry state were investigated. In total, 61 known and 81 novel miRNA were identified in dry seeds. The highest level of expression was found in four conserved miRNA families i.e. miR159, miR156, miR166 and miR168. However, the most astonishing result was the lack of significant differences in the level of almost all miRNAs in seed samples with significantly different viability. This result reveals that miRNAs in dry seeds are extremely stable. This is also the first identified RNA fraction that is not deteriorating along to the loss of seed viability. Moreover, the novel miRNA hvu-new41, with higher expression in seeds with the lowest viability was detected by RT-qPCR, has the potential to become an indicator of the decreasing viability of seeds during storage in a dry state. It might be responsible for the removal of (1-3.1-4)-beta-D-glucanase transcripts and lowering or completely blocking the synthesis of this key enzyme for seed germination.

Project description:Analysis of long-term freezing on the stability of transcriptome profiles in PAXgene stabilized whole blood samples. In the present study it was tested if long-term freezing of PAXgene RNA tubes (up to one year) has an influence on the transcriptome profile of peripheral whole blood samples. Results indicated that gene expression profiles of whole blood samples stabilized with PAXgene RNA tubes remain stable for at least 1 year. Total RNA was obtained from peripheral whole blood samples collected in PAXgene RNA tubes of healthy human subjects. RNA was either isolated after 24h storage at room temperature or after freezing of PAXgene RNA tubes for up to 1 year (6 weeks, 6 months and 12 months).

Project description:Purpose: To elucidate the physiological and molecular mechanisms underlying seed development, we conducted a genome-wide transcriptional profiling of developing seeds of ‘Sarsyun’ at four different time points (21, 28, 35, and 42 DAF). 34,423 contigs from four different developing seeds (21, 28, 35, and 42 DAF) were analyzed for transcript abundance and changes to the timing of transcript abundance in relation to the accumulation of seed storage products. Most genes involved in seed photosynthesis and carbohydrate metabolism were highly expressed at 21 or 28 DAF and were subsequently downregulated. Expression of genes coding for oleosins and fatty acid synthesis and elongation markedly increased at 28 DAF through 35 DAF, respectively, remaining high thereafter. Expression of major storage protein genes increased at 28 or 35 DAF. Overall, our results showed that dynamic changes to transcript abundance of most genes in relation to seed storage products occurred between 28 and 35 DAF.
