Description
Cdh1 regulates not only mitotic phase and G1 phase, but also G2 checkpoint under irradiation-induced DNA damage. Despite several reports indicating its potential as tumor suppressor, how Cdh1 affects tumorigenesis or tumor progression and its clinical implementation has yet to be evaluated. Considering the pivotal role of Cdh1 on DNA repair, we hypothesized that Cdh1 loss also causes fragility of tumor cells to DNA damage under oncogenic stress or chemotherapy. To test this hypothesis, we established a Cdh1 gene-trapped B cell acute lymphoblastic leukemia (B-ALL) mouse model. Cdh1-deficient B-ALL mice survived longer than Cdh1-intact group, with higher susceptibility to DNA damage. Consistently, reverse phase protein array-based analysis of more than 200 human adult B-ALL samples showed that low Cdh1 was associated with high complete remission rates and long remission durations. Furthermore, the clinical benefit with lower Cdh1 expression diminished after relapse, supported by mouse experiments showing that secondary/tertiary transplants of Cdh1-deficient B-ALL cells developed more progressive/resistant disease than Cdh1-intact group. This indicated that prolonged inactivation of Cdh1 eventually develops resistant clones. Our results collectively demonstrated that Cdh1 is a potential predictive biomarker of B-ALL chemosensitivity, but also alerting that synthetic lethality by targeting DNA repair system may eventually induce resistant disease due to genetic instability.

Description
Peripheral circadian clocks regulate many aspects of physiology. In this study we deleted the core circadian clock component Bmal1 specifically in mouse adipocytes in order to study the role of the adipocyte clock in energy homeostasis and body weight. We used microarrays to indentify changes in gene expression in the adipose tissue of mice lacking a functional adipocyte circadian clock and identified a small number of up- and down- regulated genes.

Description
In previous studies, human dental pulp stem cells (hDPSCs) were mainly isolated from adults. In this manuscript, we tried characterization of hDPSCs isolated from an earlier developmental stage to evaluate potential usage of these cells for tissue regenerative therapy. hDPSCs isolated at the crown-completed stage showed a higher proliferation rate than those isolated at the later stage. When the cells from either group were cultured in medium promoting differentiation towards cells of the osteo/odontoblastic lineage, both became alkaline phosphatase positive, produced calcified matrix, and were also capable of forming dentin-like matrix on scaffolds in vivo. However, during long-term passage, these cells underwent a change in morphology and lost their differentiation ability. The results of a DNA array experiment showed that the expression of a number of genes, such as WNT16, was markedly changed with increasing number of passages, which might have caused the loss of their characteristics as hDPSCs.

Description
Neutrophils provide immune protection against pathogens but also may promote tissue injury in inflammatory diseases. Although neutrophils are generally considered as a relatively homogeneous population, evidence for heterogeneity is emerging. Under steady-state conditions, neutrophil heterogeneity may arise from ageing and the replenishment by newly released neutrophils from the bone marrow.

Neutrophil ageing is regulated by the microbiome.

Description
The spectrum of genetic mutations differs among cancers in different organs, implying a cellular context-dependent effect of the genetic aberrations. However, the extent to which the cellular context affects the consequences of oncogenic mutations remains to be fully elucidated. We reprogrammed colon tumor cells in an Apc Min/+ mouse model, in which the loss of the Apc gene plays a critical role in tumor development, and established reprogrammed tumor cells (RTCs) that exhibit pluripotent stem cell (PSC)-like signatures of gene expression. We show that the majority of the genes in the RTCs that were affected by the Apc mutations did not overlap with the genes that were affected in the intestine or those that were affected by the accumulation of beta-catenin in PSCs. The RTCs lacked pluripotency but exhibited the increased expression of Cdx2 and a differentiation propensity that was biased toward the trophectoderm cell lineage. The genetic rescue of the mutated Apc allele conferred pluripotency on the RTCs and enabled their differentiation into various cell types in vivo. The re-disruption of Apc in the RTC-derived differentiated cells resulted in neoplastic growth that was exclusive to the intestine, yet the majority of intestinal lesions remained pre-tumoral microadenomas. These results highlight the significant influence of the cellular context on gene regulation, cellular plasticity, and cellular behavior in response to the loss of the Apc function. Our results also imply that transition from microadenomas to macroscopic tumors is reprogrammable, which underscores the importance of epigenetic regulation on colon tumor promotion.

Description
Cell cycle quiescence is a critical feature contributing to haematopoietic stem cell (HSC) maintenance. Although various candidate stromal cells have been identified as potential HSC niches, the spatial localization of quiescent HSC in the bone marrow (BM) remains unclear. Here, using a novel approach that combines whole-mount confocal immunofluorescence imaging technique and computational modelling to analyse significant tridimensional associations among vascular structures, stromal cells and HSCs, we show that quiescent HSCs associate specifically with small arterioles that are preferentially found in endosteal BM. These arterioles are ensheathed exclusively by rare Nestin-GFP-peri/NG2+ pericytes, distinct from sinusoid-associated Nestin-GFP-retic/LepR+ cells. The present RNA-seq study sought to obtain a comprehensive understanding of the differences between the two distinct HSC cellular niches. Overall design: mRNA profiles of sorted Nestin-GFP-peri and -GFP-retic bone marrow stromal cells were generated from pooled mice in triplicate by Illumina HiSeq 2000 sequencing.
