Neural stem cells (NSCs) are considered to be the cell of origin glioblastoma multiforme (GBM). However, genetic alterations that transform NSCs into glioma-initiating remain elusive. Using a unique transposon mutagenesis strategy mutagenizes in culture, followed by additional rounds generate tumors vivo, we have identified genes and signaling pathways can cells. Mobilization Sleeping Beauty transposons induced immortalization astroglial-like cells, which were then able with characteristics...
Neurodegeneration has been shown to induce microglial activation and the infiltration of monocyte‐derived macrophages into CNS, resulting in coexistence these two populations within same lesion, though their distinct features remain elusive. To investigate impact rod photoreceptor degeneration on activation, we generated a toxin‐mediated genetic model degeneration. Rod injury induced proliferation migration toward photoreceptors. Bone marrow transplantation revealed invasion retina, with...
Abstract Background Model checking approaches were applied to biological pathway validations around 2003. Recently, Fisher et al . have proved the importance of model approach by inferring new regulation signaling crosstalk in C. elegans and confirming with experiments. They took a discrete state-based explore all possible states system underlying vulval precursor cell (VPC) fate specification for desired properties. However, since both continuous features appear be an indispensable part...
The derivation of induced pluripotent stem (iPS) cells from individuals genetic disorders offers new opportunities for basic research into these diseases and the development therapeutic compounds. Severe congenital neutropenia (SCN) is a serious disorder characterized by severe at birth. SCN associated with heterozygous mutations in neutrophil elastase [elastase, neutrophil-expressed (ELANE)] gene, but mechanisms that disrupt have not yet been clarified because current lack an appropriate...
Abstract To analyze cell lineage-specific transitions in global transcriptional and epigenetic changes during retinogenesis, we purified retinal cells from normal mice postnatal development into two fractions, namely, photoreceptors other cells, based on Cd73 expression, performed RNA sequencing ChIP of H3K27me3 H3K4me3. Genes expressed the photoreceptor lineage were marked with H3K4me3 Cd73-positive fraction; however, level was very low both -negative populations. may be involved...
Primary biliary cholangitis (PBC) is a chronic and cholestatic autoimmune liver disease caused by the destruction of intrahepatic small bile ducts. Our previous genome-wide association study (GWAS) identified six susceptibility loci for PBC. Here, in order to further elucidate genetic architecture PBC, GWAS was performed on an additional independent sample set, then meta-analysis with our based whole-genome single nucleotide polymorphism (SNP) imputation analysis total 4,045 Japanese...
Recent studies have documented various roles of adrenal corticosteroid signaling in cardiac physiology and pathophysiology. It is known that glucocorticoids aldosterone are able to bind glucocorticoid receptor (GR) mineralocorticoid receptor, these ligand-receptor interactions redundant. It, therefore, has been impossible delineate how nuclear receptors couple with ligands differentially regulate gene expression for operation their distinct functions the heart. Here, particularly define role...
Using quantitative PCR-based miRNA arrays, we comprehensively analyzed the expression profiles of miRNAs in human and mouse embryonic stem (ES), induced pluripotent (iPS), somatic cells. Immature cells were purified using SSEA-1 or SSEA-4 used for profiling. Hierarchical clustering consensus by nonnegative matrix factorization showed two major clusters, ES/iPS other cell groups, as previously reported. Principal components analysis (PCA) to identify that segregate these groups identified...
Recent advances have enabled the direct induction of human tissue-specific stem and progenitor cells from differentiated somatic cells. However, it is not known whether hepatic (hHepPCs) can be generated other cell types by lineage reprogramming with defined transcription factors. Here, we show that a set three factors, FOXA3, HNF1A, HNF6, induce umbilical vein endothelial to directly acquire properties hHepPCs. These induced hHepPCs (hiHepPCs) propagate in long-term monolayer culture...
We propose a state space representation of vector autoregressive model and its sparse learning based on L1 regularization to achieve efficient estimation dynamic gene networks time course microarray data. The proposed method can overcome drawbacks the model; assumption equal interval lack separation ability observation systems noises in former modularity network structure latter method. However, simple implementation requires calculation large inverse matrices number times during parameter...
