Project description:To investigate the collective role of zinc finger proteins in adipogenesis, we induced adipogenesis using human mesenchymal stem cells (MSC) and compared the gene expression profiles using human Illumina beads arrays. We performed three independent experiments of time-series analysis (0h, 1h, 12h, 24h, 2d, 4d, 6d, 9d, 12d, 15d after induction of adipogenesis) in order to comprehensively capture the dynamic profiles of transcriptome during differentiation. Statistical filtering based on Analysis of Variance (ANOVA; p-value < 0.001, FDR 5%) and Gene Ontology classification using the Human Gene Nomenclature Database (HGNC) identified 618 out of 678 zinc finger proteins (ZFPs) that were significantly expressed during adipogenesis. Moreover, 34 out of 618 genes were differentially expressed more than 2-fold up or down regulated. The K-means clustering analysis further revealed four dynamic expression patterns: one gene in early-response, seven genes in transient, twenty genes in progressively-induced and four genes in the down-regulated, demonstrating the dynamic involvement of ZFPs in the process of adipocyte differentiation and maturation. Total RNA obteind from 10 different time points (0h, 1h, 12h, 24h, 2d, 4d, 6d, 9d, 12d, 15d) during adipogenesis from human Mesenchymal stem cell (MSC) to Adipocyte (ADP). Adipogensis was induced by the different cocktail of chemical compunds containing human-insulin, dexamethasone, indomethacin and IBMX.

Project description:C2H2 zinc finger proteins represent the largest and most enigmatic class of human transcription factors. Their C2H2 arrays are highly variable, indicating that most will have unique DNA binding motifs. However, most of the binding motifs have not been directly determined. We have determined the binding sites and motifs of 119 C2H2 zinc finger proteins and the expression pattern of 80 cell lines overexpressing C2H2 zinc finger proteins in order to study the role of C2H2 zinc finger proteins in gene regulation. We expressed GFP-tagged C2H2-ZF proteins in stable transgenic HEK293 cells. Total RNA was isolated using Trizol and sequencing libraries were constructed using TruSeq Stranded Total RNA Library Prep Kit with Ribo-Zero Gold or TruSeq RNA Library Preparation Kit v2.

Project description:Zinc dyshomeostasis has been involved in the pathogenesis of cardiac hypertrophy; however, the dynamic regulation of intracellular zinc and its downstream signaling in cardiac hypertrophy remain largely unknown. Here we screened ZIP (SLC39) family members that were responsible for zinc uptake in a phenylephrine (PE)-induced cardiomyocyte hypertrophy model. We found that Slc39a2 was the only member that was altered at mRNA level by PE treatment in neonatal rat ventricular myocytes (NRVMs), but its protein level was not affected. Zincpyr1 staining showed a significant decrease in zinc uptake after PE treatment or after Slc39a2 knockdown in NRVMs, indicating an inhibition of its transport activity during hypertrophy. Slc39a2 deficiency caused spontaneous hypertrophy in NRVMs, and further exacerbated the hypertrophic responses after PE treatment. RNA sequencing analysis confirmed a largely aggravated pro-hypertrophic transcriptome reprogramming after Slc39a2 knockdown. Interestingly, the innate immune pathways, including NOD signaling, TOLL-like receptor, NFB, and IRFs, were substantially enriched after Slc39a2 knockdown. Whereas IRF7, the most sensitive among all IRFs, did not mediate the effect of Slc39a2 in hypertrophy, pro-hypertrophy phosphorylations of NFB and STAT3 were significantly enhanced after Slc39a2 knockdown, in parallel with degradation of IkBα protein. Our data demonstrate that SLC39A2-mediated zinc homeostasis contributes to the remodeling of innate immune signaling in cardiomyocyte hypertrophy, and provide novel insights into the pathogenesis of heart failure and its treatment.

Project description:Zinc Finger Nucleases (ZFNs) facilitate precise editing of DNA enabling targeted genomic modifications in vivo. ZFNs have been employed to obtain genetically modified plants and animals, and cell-based therapies utilizing ZFNs are undergoing clinical trials. However, many ZFNs display dose-dependent toxicity presumably due to the generation of undesired double stranded breaks at off-target sites within the genome. To evaluate the parameters influencing the functional specificity of ZFNs, we compared the in vivo activity of ZFN variants targeting the zebrafish kdrl locus, which display both high on-target activity and dose-dependent toxicity. We evaluated their functional specificity by assessing lesion frequency at 141 potential off-target sites within the zebrafish genome using Illumina sequencing. Only a minority of these off-target sites displayed significant lesion frequency with kdrl ZFNs. Furthermore, we find that active off-target sites appear to be defined by the thermodynamics of zinc finger-DNA recognition. Surprisingly, we observed that the zinc finger protein specificity and the choice of the engineered dimerization domain of the FokI nuclease could independently influence the fidelity of these ZFNs. The results of this study have implications for the assessment of likely off-target sites within a genome and point to both ZFP-dependent and –independent mechanisms of potential improvement for engineering ZFNs with higher levels of precision. Examined lesions at 141 off-target sites for various treatments of ZFNs and compare to the untreated sample stage 1: raw read but missing quality values stage 2: fastq files available from SRA

Project description:Programmable regulation of gene expression promises to be a powerful therapeutic venue for diseases caused by the misexpression of genes, haploinsufficiencies, or gain of function mutations. While dCas9-effector domain fusions have been used to alter expression levels, their in vivo application is limited by size and immunogenicity. Conversely, the Cys2His2 Zinc Finger domain offers ideal characteristics for in vivo use. However, their intricate engagement with the DNA has made the design of Zinc Finger arrays challenging. We here describe the screening of 49 billion protein-DNA interactions and development of the first deep learning model that solves Zinc Finger design for any genomic target. We demonstrate the versatility of designed Zinc Fingers as nucleases and as activators or repressors by seamlessly reprogramming human transcription factors.

Project description:Cys2-His2 Zinc finger genes (ZNFs) form the largest family of transcription factors in metazoans. Zebrafish posess a subfamily characterized by the presence of a domain dubbed Fish N-terminal Zinc finger associated (FiNZ). FiNZ-ZNFs are expressed at the onset of zygotic genome activation in zebrafishh, and blocking FiNZ-ZNF translation using morpholinos during early zebrafish embryogenesis results in a broad de-repression of young, transcriptionally active TEs.
