Description
Novel analytic tools are needed to elucidate the molecular basis of leukemia-relevant gene mutations in the post-genome era. We generated isogenic leukemia cell clones in which the FLT3 gene was disrupted in a single allele using TALENs. Isogenic clones with mono-allelic disrupted FLT3 were compared to an isogenic wild-type control clone and parental leukemia cells for transcriptional expression, downstream FLT3 signaling and proliferation capacity. The global gene expression profiles of mutant K562 clones and corresponding wild-type controls were compared using RNA-seq. The transcriptional levels and the ligand-dependent autophosphorylation of FLT3 were decreased in the mutant clones. TALENs-mediated FLT3 haplo-insufficiency impaired cell proliferation and colony formation in vitro. These inhibitory effects were maintained in vivo, improving the survival of NOD/SCID mice transplanted with mutant K562 clones. Cluster analysis revealed that the gene expression pattern of isogenic clones was determined by the FLT3 mutant status rather than the deviation among individual isogenic clones. Differentially expressed genes between the mutant and wild-type clones revealed an activation of nonsense-mediated decay pathway in mutant K562 clones as well as an inhibited FLT3 signaling. Our data support that this genome-editing approach is a robust and generally applicable platform to explore the molecular bases of gene mutations. Overall design: Global gene expression profiles of three isogenic K562 mutant clones (clones k20, k112, k324) and three randomly selected wild-type clones (clones kw1, kw2, kw3) were generated by RNA-seq, using Illumina Hiseq 2000.

Description
The pancreatic beta cell function failure is the core event of type 2 diabetes mellitus. High levels of free fatty acid and glucose are two main factor that induced pancreatic beta cell function failure. Long term exposure to palmitate can induced pancreatic beta cell apoptoss and impaired insulin secretion in vivo and in vitro, called lipotoxicity. The lipotoxicity often coupled with high glucose, their combination form called glucolipotoxcity. We carried out temporal transcriptome and proteome studies investigating the evolution of molecular events in Ins1 cells stimulated by palmitate for different times. And through compared the transcriptome and proteome between lipotoxicity and glucolipotoxicity explain the mechanism of glucolipotoxicity more harmfull to beta cell. Overall design: we performed a time-course large-scale transcriptome of INS1 cells induced by 0.5 mM palmitate and 0.5 mM palmitate with 27.8 mM glucose at four time points (8, 16, 24 and 48 h) using MAPS method

Description
To design an effective antibody therapy to improve clinical outcomes in leukemia, the identification of novel cell surface antigens is needed. Herein, we demonstrate a role for transmembrane tumor necrosis factor-in leukemia. To characterize tmTNF- expression in acute leukemia, normal hematopoietic cells, and non-hematopoietic tissues, we used a monoclonal antibody, termed C1, which specifically recognizes the tmTNF- domain. We found that tmTNF- was preferentially expressed by acute leukemia and leukemia stem cells. More abundant expression correlated with poor risk stratification, extramedullary infiltration, and adverse clinical parameters. Moreover, knockdown of tmTNF-+ expression rendered leukemia cells more sensitive to chemotherapy in vitro and delay regeneration of leukemia in NODSCID mice. Targeting tmTNF- by C1 resulted in leukemia cell killing via antibody-dependent cell-mediated and complement -dependent cytotoxicity in vitro, and inhibited leukemia cell growth in vivo while simultaneously sparing normal hematopoietic cells. Notably, C1 administration impaired the regeneration of leukemia in secondary serial transplantationin to NOD-SCID mice.

Description
Reprogramming to pluripotency after overexpression of OCT4, SOX2, KLF4 and MYC is accompanied by global genomic and epigenomic changes. Histone modification and DNA methylation states in iPSCs have been shown to be highly similar with embryonic stem cells (ESCs). However, epigenetic differences still exist between iPSCs and ESCs. In particular, aberrant DNA methylation states found in iPSCs are a major concern for using iPSCs in a clinical setting. Thus, it is critical to find factors that regulate DNA methylation states in reprogramming. Here, we found that the miR-29 family is an important epigenetic regulator during human somatic cell reprogramming. Our global DNA methylation and hydroxymethylation analysis shows that DNA demethylation is a major event mediated by miR-29a depletion during early reprogramming, and that iPSCs derived from miR-29a depletion are epigenetically closer to ESCs. Our findings uncover an important miRNA-based approach to generate clinically robust iPSCs. Overall design: Bisulphite converted gDNAs of D551 fibroblasts transduced for 3 days with overexpression of DNMTs, TETs, TDG and OSKM or miR29a/b/c and control sponge were hybridized into Illumina Infinium HumanMethylation 450K Beadchip.

Description
Little is known about the roles of methyl-CpG-binding domain protein 2 (MBD2), a reader of DNA methylation, in T-cell acute lymphoblastic leukemia (T-ALL). Here, we investigated the role of MBD2 in T-ALL by using an Mbd2 knockout mouse model. We found that MBD2 ablation impeded the progression and maintenance of Notch1-driven T-ALL.Our data reveals essential roles for MBD2 in lymphopoiesis and T-ALL and support an intriguing potential of MBD2 as a therapeutic target for T-ALL.

Description
Prostate cancer is the most common cancer in men and cardiac glycosides inhibit prostate cancer cell proliferation. In order to investigate the mechanism by which cardiac glycosides inhibit prostate cancer cells, we observed genome-wide RNA expression in prostate cancer LNCaP-abl cells, hormone resistant cells, after the cardiac glycoside treatment using RNA-Seq. In addition, we profiled LNCaP-abl cells after androgen receptor (AR) knockdown to observe whether cardiac glycoside effect on RNA expression is similar to that of AR knockdown. Overall design: Observation of three cardioglycosides, Digoxin, Peruvoside and Strophanthidin, and AR knockdown regulated RNA expression in LNCaP-abl with RNA-Seq (each triplicates)
