Project description:The goal of this experiment is to evaluate the potential for utilising this oligonucleotide microarray in other species and genera of the Pinaceae family by using comparative RNA hybridizations in four different spruces (Picea spp), two pines (Pinus spp.) and a larch (Larix laricina), across two tissues, xylem and phelloderm.

One-color comparison of 7 conifer species in 2 tissue types: xylem and phelloderm. Between 4 and 28 biological repetitions per sample type, depending on the species, for a total of 142 slides.
Project description:Purpose: The goal of this study is to compare endothelial small RNA transcriptome to identify the target of OASL under basal or stimulated conditions by utilizing miRNA-seq. Methods: Endothelial miRNA profilies of siCTL or siOASL transfected HUVECs were generated by illumina sequencing method, in duplicate. After sequencing, the raw sequence reads are filtered based on quality. The adapter sequences are also trimmed off the raw sequence reads. rRNA removed reads are sequentially aligned to reference genome (GRCh38) and miRNA prediction is performed by miRDeep2. Results: We identified known miRNA in species (miRDeep2) in the HUVECs transfected with siCTL or siOASL. The expression profile of mature miRNA is used to analyze differentially expressed miRNA(DE miRNA). Conclusions: Our study represents the first analysis of endothelial miRNA profiles affected by OASL knockdown with biologic replicates.
Project description:Masson pine (Pinus massoniana) has evolved some adaptations for growth in low P soils. To elucidate these mechanisms, we investigated global gene expression profiles of the masson pine responding to long-term phosphorus starvation and different Pi levels (P1, 0.01 mM P; P2, 0.06 mM P). Analysis used phosphorus-sufficient treatment RNA as control samples for comparison to the experimental samples (P1 and P2) taken at 12, 24, 48 and 60 day. Indirect comparisons were made across multiple arrays with raw data pulled from different channels for data analysis and comparison to the control data.
Project description:We report the application of ATACseq to differentiating ATDC5 cells with the aim of identifying how chromatin architecture is changing as these cells move from pre-chondrocytes to differentiated chondrocytes. Raw data was generated by sequencing using the Novaseq6000 with 50bp single end reads. Trimming to remove adapters or poor-quality reads was performed with no sequence below 30 nucleotides in length used in the analysis. We found that there were significant changes in chromatin accessibility at both days 3 and 10 of differentiation. Using diffBind, differential peaks were identified at day 3 and 10. These peaks were further analyzed for enriched transcription factor binding sites and identified motifs for the RUNX family transcription factors as well as SOX9.
