Project description:Using quantitative proteomics we identified group of synaptic genes with decreased protein synthesis during homeostatic plasticity. To obtain further information about their mRNA levels/sequences (3’UTR) we performed polyA RNAseq. Using EISA analysis of Ribominus RNAseq dataset we could further differentiate between transcriptional respective post-transcriptional dependent alterations in mRNA levels. In addition Ribominus RNAseq from cell body and processes (dendrites, axons) RNA samples showed us local changes in mRNA levels during homeostatic plasticity. At the end, small RNAseq helped us to identify miRNAs that are increased during homeostatic plasticity and might regulate downregulated genes.
Project description:Ba/F3 cells were transformed after transfection with CRISPR/CAS9 + gRNA vs target gene. Oligoclonal cell population was flow sorted into single cells and processes for RNAseq.
Project description:The goal of this study was to assay the extent of variation in chromatin organization between 3 ant castes (major and minor female workers and males) in one colony of Camponotus floridanus carpenter ant using ChIPseq. 45 samples total: 30 ChIP samples and 3 inputs for total histone H3, 7 histone H3 PTMs and RNA Pol II in major, minor, and male ants; CBP in major and minor ants; the major H3K27ac sample was replicated. 4 ChIP samples for H3 and H3K27ac in brains of majors and minors, and 2 inputs. 2 RNAseq samples for major and minor ants head+thorax; 4 RNAseq samples for brain (majors and minors with 2 replicates each).
Project description:In this study we have used ChIPseq analysis to perform comprehensive mapping of the binding profile of the cAMP receptor protein (CRPMt) of M. tuberculosis combined with RNAseq studies to further investigate the transcriptional response following crp gene deletion and under alternative growth conditions.
Project description:CD34 positive hematopoietic stem cells were differentiated into erythroid lineage. Next generation sequencing (NGS) of 5hmC affinity pulldown and RNAseq were performed in four time point of different stages of erythroid differentiation. 4 RNA-Seq Samples (d0, d3, d7 and d10); 4 affinity-pulldown (d0, d3, d7 and d10), and 4 input samples (d0, d3, d7 and d10).
Project description:Mutations in Bicaudaul C 1 (BICC1), evolutionary conserved RNA-binding protein, cause renal cysts in mice and humans. These renal cysts are reminiscent of Polycystic Kidney Disease (PKD). How BICC1 is involved in the pathogenesis of polycystic kidney disease is still unknown. Recent studies highlighted that HNF4A plays a role in the regulation of metabolic pathways deregulated in this renal disease. Moreover, Menezes et al. [2012, https://doi.org/10.1371/journal.pgen.1003053] showed that combined kidney inactivation of Hnf4a and Pkd1 in mice significantly worsened the cystic phenotype. Here we investigated whether the DNA binding and transcriptional activity of HNF4A might be deregulated in kidneys from Bicc1 mouse model of polycystic kidney disease. HNF4A, H3K27ac, H3K4me1 ChIPseq experiments were performed in kidneys from male and female Bicc1 WT and KO mice. From the contralateral kidneys of the same animals used for the ChIPseq experiments, the total RNA was extracted for gene expression profiling by RNAseq. The RNAseq data was used to support the ChIP-seq analysis and to reveal deregulated pathways in BICC1 mutants.
