Project description:Genome wide methylation profiling of SUM159PT NNMT WT, KOs and KOd cells. The Illumina human Infinium Methylation EPIC BeadChip was used to measure global DNA methylation on CpG from 850 k probes. Samples include three experimental replicates from each cell line.
Project description:Genome-wide gene expression pattern of E47 KO versus WT HSCs from primary and secondary recipient mice were analysis using Agilent one-color micro-array analysis.
Project description:Genome-wide gene expression pattern of E47 KO versus WT HSCs from primary and secondary recipient mice were analysis using Agilent one-color micro-array analysis. Two replicates from 4 samples are analyzed. The sample from the WT mouse were set as their reference sample.
Project description:Gene profiling, using microarray technology, was used to identify differentially expressed genes in bone marrow-differentiated macrophages of Hem1 KO versus Hem1 WT mice
Project description:The cellular heterogeneity within a tumor can be determined by core genetic and epigenetic programs that operate in certain cells (tumor initiating cells – TICs), providing them with the degree of plasticity needed for induction of metastasis and resistance to therapy. Here we show that the metabolic enzyme nicotinamide N-methyl transferase (NNMT) promotes TIC plasticity in Estrogen Receptor (ER) alpha negative breast cancer. NNMT downregulation delays tumor formation and its full depletion impairs metastasis formation in mice. Mechanistically, NNMT loss increases deposition of H3K9-me2/3 and H3K27-me3 at the promoter of genes involved in stem cell regulation, shutting down their expression and upregulating luminal differentiation genes. This study reveals a major function of NNMT in maintaining core epigenetic programmes that promote TIC self-renewal and metastasis and that repress luminal differentiation.
Project description:We generated NUP133 WT and KO podocytes to model human hereditary SRNS in vitro. A subtype of SRNS is caused by monogenetic mutations of the nuclear pore complex including NUP133. Immortalized human podocytes were genome edited applying the CRISPR/Cas9 technique and two independent NUP133 sgRNAs. Two monoclonal cell backgrounds were used to create two matching sets of NUP133 WT and KO cells (WT-1 versus KO-1 and WT-2 versus KO-2). Transcriptome profiling (RNA-Sequencing) and differential gene expression analysis was performed in duplicate for each cell line. NUP133 KO podocytes exhibit vast transcriptional changes compared to WT cells.
