Description
The zinc finger factor Insm1 is known to regulate differentiation of pancreatic cells during development, Here we show that Insm1 is essential for the maintenance of functionally mature pancreatic cells in mice.
Publication Title
Insm1 cooperates with Neurod1 and Foxa2 to maintain mature pancreatic β-cell function.

Description
Dorsomorphin is a small molecule inhibitor of type I bone morphogenic protein receptors (BMPRs). We have found that dorsomorphin affects a wide range of T cell function. In order to obtain the bigger picture of the effects of DM in T cell activation. transcriptomic analysis was performed using mouse primary CD25-CD4+ T cells with either DM (4 M) or vehicle in the presence or absence of stimulation by anti-CD3 and -CD28 antibodies.

Description
To clarify how Foxp3 regulates its target genes, we performed co-immunoprecipitation experiments and found that Foxp3 physically bound to AML1/Runx1 (Ono, M. et al, Nature, 2007). In this series of study, we compared gene regulations by AML1, wild type Foxp3, and a Foxp3 mutant with defective binding to AML1.

Description
Pseudoautosomal regions (PAR1 and PAR2) in eutherians retain homologous regions between the X and Y chromosomes that play a critical role in the obligatory X-Y crossover during male meiosis. Genes that reside in the PAR1 are exceptional in that they are rich in repetitive sequences and undergo a very high rate of recombination. Remarkably, murine PAR1 homologs have translocated to various autosomes, reflecting the complex recombination history during the evolution of the mammalian X chromosome. We now report that the SNF2-type chromatin remodeling protein ATRX controls the expression of eutherians ancestral PAR1 genes that have translocated to autosomes in the mouse. In addition, we have identified two potentially novel mouse PAR1 orthologs. We propose that the ancestral PAR1 genes share a common epigenetic environment that allows ATRX to control their expression.

The role of Gata2 in regulating uterine function including fertility, implantation, decidualization and P4 signaling in the mouse was investigated by the conditional ablation of Gata2 in the uterus using the (PR-cre) mouse and ChIP-seq for in vivo GATA2 binding sites in the murine uterus upon acute P4 administration.

Lung cancer remains the leading cause of cancer death. Genome sequencing of lung tumors from patients with Squamous Cell Carcinoma has identified SMAD4 to be frequently mutated. Here we used a novel mouse model to determine the molecular mechanisms regulated by loss of Smad4 which lead to lung cancer progression. Mice with ablation of Pten and Smad4 in airway epithelium developed metastatic adenosquamous tumors. Comparative transcriptomic and in vivo cistromic analyses determined that loss of PTEN and SMAD4 resulted in activation of the ELF3 and the ErbB2 pathway due to decreased ERRFI1s expression, a negative regulator of ERBB2 in mice and human cells. The combinatorial inhibition of ErbB2 and Akt signaling attenuated tumor progression and cell invasion, respectively. Expression profiles analysis of human lung tumors substantiated the importance of the ErbB2/Akt/ELF3 signaling pathway as both prognostic biomarkers and therapeutic drug targets for treating lung cancer.

Description
Interleukin (IL)-27 is a key immunosuppressive cytokine that counters T helper 17 (Th17) cell-mediated pathology. To identify mechanisms by which IL-27 might exert its immunosuppressive effect, we analyzed genes in T cells rapidly induced by IL-27. We found that IL-27 priming of nave T cells upregulated expression of programmed death ligand 1 (PD-L1) in a signal transducer and activator of transcription (STAT)1-dependent manner. When co-cultured with nave CD4+ T cells, IL-27-primed T cells inhibited the differentiation of Th17 cells in trans through a PD-1-PD-L1 interaction. In vivo, co-administration of nave TCR transgenic T cells (2D2 T cells) with IL-27-primed T cells expressing PD-L1 inhibited the development of Th17 cells and protected from severe autoimmune encephalomyelitis. Thus, these data identify a suppressive activity of IL-27, by which CD4+ T cells can restrict differentiation of Th17 cells in trans.
