Description
"Omics" technologies have been developed to understand the whole complex microbial systems; however, most omics studies reported so far were utilized to analyze the living matters of single-species. To understand the cell-cell interaction in the gut microbial complex, we selected to examine the interaction of Escherichia coli O157:H7 (O157) and Bifidobacterium longum (BL), known as a pathogenic and a commensal bacteria, as a first step for understanding the whole gut microbial complex. We have developed a novel time-lapse 2D-NMR metabolic profiling system in order to measure the extracellular metabolites, which are considered a key factor to understand the bacterial crosstalk. Furthermore, in combination with transcriptome and proteome analysis, we found that the relationship between BL and O157 could be partially regarded as the producer and the consumer of nutrients, especially in the case of serine and aspartate metabolism. These findings suggest that our novel profiling systems could be a powerful tool toward understanding crosstalk of the whole microbial complex such as the gut, industrial bioreactors or environmental microbial communities.

Description
Pompe disease is caused by autosomal recessive mutations in the GAA gene, which encodes acid alpha-glucosidase. Although enzyme replacement therapy has recently improved patient survival greatly, the results in skeletal muscles and for advanced disease are still not satisfactory. Here, we report the derivation of Pompe disease induced pluripotent stem cells (PomD-iPSCs) and their potential for pathogenesis modeling, drug testing and disease marker identification. PomD-iPSCs maintained pluripotent features, and had low GAA activity and high glycogen content. Cardiomyocyte-like cells (CMLCs) differentiated from PomD-iPSCs recapitulated the hallmark Pompe disease pathophysiological phenotypes, including high levels of glycogen, abundant intracellular LAMP-1- or LC3-positive granules, and multiple ultrastructural aberrances. Drug rescue assessment showed that exposure of PomD-iPSC-derived CMLCs to rhGAA reversed the major pathologic phenotypes. Further, L-carnitine and 3- methyladenine treatment reduced defective cellular respiration and buildup of phagolysosomes, respectively, in the diseased cells. By comparative transcriptome analysis, we identified glycogen metabolism, lysosome and mitochondria related marker genes whose expression robustly correlated with the therapeutic effect of drug treatment in PomD-iPSC-derived CMLCs. Collectively, these results demonstrate that PomD-iPSCs are a promising in vitro disease model for development of novel therapeutic strategies for Pompe disease.

Tankyrase enhances beta-catenin signaling via PARsylation and subsequent degradation of Axin, a negative regulator of beta-catenin. Tankyrase inhibitors stabilize Axin and suppress beta-catenin signaling. We developed a novel tankyrase inhibitor, RK-287107.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
We have found that histone H2B is GlcNAcylated at residue S112 by O-GlcNAc transferase and that H2B S112 GlcNAcylation fluctuates in response to extracellular glucose level. We have also found that H2B S112 GlcAcylation promotes H2B K120 ubiquitination. To investigate whether these histone modification correlate to transcriptional activation, we performed comprehensive gene expression analysis using Affymetrix GeneChip in HeLa cell cultured with different conditions, i.e. without glucose, with glucose and with FBS.

Description
Mounting evidence points to a link between a cancer possessing stem-like properties and a worse prognosis. To understand the biology, a common approach is to integrate network biology with signal processing mechanics. That said, even with the right tools, predicting the risk for a highly susceptible target using only a handful of gene signatures remains very difficult. By compiling the expression profiles of a panel of tumor stem-like cells (TSLCs) originating in different tissues, comparing these to their parental tumor cells (PTCs) and the human embryonic stem cells (hESCs), and integrating network analysis with signaling mechanics, we propose that network topologically-weighted signaling processing measurements under tissue-specific conditions can provide scalable and predicable target identification.

Description
The adaptor protein LNK (SH2B3) has emerged as an important protein in regulating B cell development B cell leukemia. Loss-of-function mutations in LNK (SH2B3) are found in Philadelphia chromosomelike acute lymphoblastic leukemia (Ph-like ALL), but how LNK regulates normal B cell development or promotes leukemogenesis remains unclear. We found that combined loss of Lnk and tumor suppressors Tp53 in mice triggers a highly aggressive and transplantable precursor B-ALL. This study aims to investigate the molecular mechanism by which LNK regulates B-ALL development. We performed expression profiling of bone marrow proB progenitors from WT, Tp53-/-, Lnk-/- and preleukemic healthy Tp53/Lnk double knockout (DKO) mice, as well as leukemic bone marrow cells from DKO mice that have developed B-ALL. Results suggest that Tp53-/-Lnk-/- B-ALLs display similar gene expression profiles to human Ph-like B-ALLs, suggesting this model for preclinical and molecular studies.
