Project description:Transcriptional profiling of mouse lung tumors comparing Dnmt3a KO/K-ras G12D mutant with Dnmt3a WT/K-ras G12D mutant. The goal is to search for the difference of mRNA abundance between Dnmt3a KO and WT tumors. Two-condition experiment, KO vs. WT tissure. Biological replicates: 12.

Project description:Gains and losses in DNA methylation are prominent genomic features of all mammalian cell types. To gain insight into mechanisms that could promote shifts in DNA 5-hydroxymethylation (5hmc) patterns and thus contribute to cell fate, including malignant transformation, we performed genome-wide mapping of 5hmc in purified wild type and Dnmt3a conditional knockout hematopoietic stem cells (HSCs) using cytosine-5-methylenesulphonate sequencing (CMS-seq). Comparing anti-CMS pulldown to input control, we identified 107,549 and 175,682 peaks of 5hmc enrichment in control and Dnmt3a knockout HSCs, respectively.

Project description:To identify soluble factors released from Dnmt3a KO macrophages that might drive differences in osteoclast differentiation, we performed RNA sequencing on unstimulated BMDMs from WT and Dnmt3a KO mice. To investigate the mechanistic basis for the inflammatory phenotype. of myeloid cells with loss of Dnmt3a,we performed reduced representation bisulfite sequencing (RRBS) on Dnmt3a KO and WT BMDMs to assess methylation changes. Concurrently, we performed ATAC-sequencing (ATAC-seq) to assess differences in chromatin accessibility between WT and Dnmt3a KO BMDMs in the context of changes in methylation. We performed chromatin immunoprecipitation sequencing (CHIP-seq) for Irf3 and Rela based on ATAC-seq analysis.
Project description:Transcriptional profiling of mouse postnatal SVZ NSCs comparing WT NSCs with KO NSCs under proliferating/undifferentiated states as well as differentiating conditions. Goal was to determine Dnmt3a-dependent gene expression changes in postnatal SVZ NSCs Two-condition experiment with a dye-swap design, WT NSCs vs. KO NSCs. Biological replicates: 4 replicates under proliferating/undifferentiation conditions, 2 replicates under differentiating conditions.
