View SamplesFus is the gene for a member of the FET family of RNA-binding proteins often involved in chromosomal translocations to generate oncogenic fusion genes in human cancers. Fus participates in multiple cellular functions, including RNA processing and transport, transcriptional regulation, and genome integrity. We uncovered its critical role in the maintenance of hematopoietic stem cells (HSCs). Fus-/- fetal livers developed normally except for a mild reduction in numbers of colony-forming cells compared to the wild type. The proliferation and differentiation of Fus-/- hematopoietic progenitors were normal in vitro. However, the number of colony-forming cells present in long-term cocultures of Fus-/- hematopoietic progenitors and stromal cells was significantly reduced. Fus-/- HSCs had an impaired long-term repopulating capacity and failed to repopulate in tertiary recipient mice. Fus-/- HSCs were highly susceptible to radiation both in vitro and in vivo and showed retardation of radiation-induced DNA damage repair. These findings define Fus as a novel regulator of HSCs and implicate it in stress-resistance and maintenance of the genomic integrity of HSCs. Therefore, it would be of importance to analyze the gene expression profiles of Fus-knockout hematopoietic stem/progenitor cells to understand its role in HSCs.
FET family proto-oncogene Fus contributes to self-renewal of hematopoietic stem cells.

View SamplesRegulation of spatiotemporal gene expression in higher eukaryotic cells is critical for the precise and orderly development of undifferentiated progenitors into committed cell types of the adult. Recently, dynamic epigenomic regulation, including chromatin remodeling and histone modifications by transcriptional coregulator complexes, has been shown to be involved in transcriptional regulation. Precisely how these coregulator complexes exert their cell-type and developing stage-specific activity is largely unknown. In this study, we aimed to isolate the histone demethylase LSD1 complex from neural cells by biochemical purification. In so doing, we identified MyT1 as a novel LSD1 complex component. MyT1 is a neural cell-specific zinc finger factor and it forms a stable multiprotein complex with LSD1 through direct interaction. Target gene analysis using microarray and ChIP assays revealed several genes, including PTEN, that were directly regulated by the LSD1-MyT1 complex. Knockdown of either LSD1 or MyT1 derepressed the expression of endogenous target genes and inhibited cell proliferation of a neuroblastoma cell line, Neuro2a. We propose that formation of tissue-specific combinations of coregulator complexes is a critical mechanism for tissue-specific transcriptional regulation.

View SamplesUnder steady-state conditions, eosinophils are abundantly found in the small intestinal lamina propria, but their physiological function is largely unexplored. We performed a global gene expression analysis to examine which genes are highly expressed by small intestinal eosinophils (CD11b+CD11c(int)MHCII-SiglecF+) compared with dendritic cells (CD11c+MHCII+).
