Project description:Purpose: To evaluate transcriptome-wide alterations in CD4+ T cells cultured under Th1-polarizing conditions in the absence of the Ikaros zinc finger transcription factor Eos via RNA-seq analysis.
Project description:Zinc finger transcriptional factor CASZ1b suppresses neuroblastoma growth. We have generated a tetracycline inducible CASZ1b expression neuroblastoma cell line (SY5YtetCASZ1b), in which CASZ1b has been transfected into SY5Y cells and its expression could be induced by treating the cells with tetracycline. Using gene expression profiling assay for the cells treated with tetracycline (Tet+) or without tetracycline (Tet-), we identified CASZ1b target genes and downstream transcriptional pathways in neuroblastoma cells.
Project description:Asthma is a chronic inflammatory airway disease characterized by airway inflammation and remodeling. The role of 15-oxo-5Z,8Z,11Z,13E-eicosatetraenoic acid (15-oxoETE), a 15-HETE metabolite catalyzed by 15-prostaglandin dehydrogenase (15-PGDH), has been relatively unexplored in asthma. In this study, we used RNA-seq to explore the effect of 15-KETE on the transcriptome of airway epithelial cells, aiming to identify its potential downstream targets and mechanisms of action.

Project description:The zinc finger transcription factor BbSmr1 regulates conidial development
Project description:Ikaros is a zinc finger (ZnF) transcription factor critical for B-cell development. The C2H2 zinc finger is the most prevalent DNA-binding motif in the mammalian proteome, with DNA-binding domains usually containing more tandem fingers than are needed for stable sequence-specific DNA recognition. To examine the reason for the frequent presence of multiple zinc fingers, we recently generated mice lacking finger 1 or finger 4 of the 4-finger DNA-binding domain of Ikaros. Each mutant strain exhibited a specific subset of the phenotypes observed with Ikaros null mice, and revealed that different subsets of fingers within multi-finger transcription factors can regulate distinct target genes and biological functions. We here study the effect of these mutants on mature B-cells with transcriptome profiling of sorted IgM+ B-cells from BM of wt and the two ZnF mutants (RNA-Seq).
Project description:Genome-wide studies have uncovered multiple independent signals at the RREB1 locus associated with altered type 2 diabetes risk and related glycemic traits. However, little is known about the function of the zinc finger transcription factor RREB1 in glucose homeostasis or how changes in its expression and/or function influences diabetes risk.
