Description
Decay of mRNAs initiates with shortening of the poly(A) tail. Although the CCR4-NOT complex participates in deadenylation, how it becomes activates remain obscure. We show that complete deficiency in CNOT3, subunit 3 of this complex, is lethal in mice, but that heterozygotes survive as lean mice with hepatic and adipose tissues containing reduced lipid levels. Cnot3+/- mice have enhanced metabolic rates and remain lean on high-fat diets. We further provide evidence suggesting that CNOT3, by changing its level in response to feeding conditions, affects the activity of the CCR4-NOT deadenylase against poly(A) tails of specific mRNAs coding for proteins involved in metabolism of carbohydrates and fats.

Description
To obtain insight into the genetic basis of the increase of functional activity of memory B cells over time, we compared the gene expression profiles of day 7 and day 40 NP-specific/IgG1 memory B cells, GC B cells and plasma cells in immunized WT mice and nave B cells, before and after activation in vitro.

Description
Bcl6 germline deletion causes a prominent inflammatory disease, owing to over-expression of Th2 cytokines, and affects the properties of B cells prior to immunization. Therefore we established the B cell-specific Bcl6 deletion mice and analyze the gene expression of naive B cells under physiological conditions.

Description
Gene expression in self-renewing epithelial tissues is controlled by cis- and trans-activating regulatory factors that mediate responses to exogenous agents capable of causing tissue damage, infection, inflammation, or tumorigenesis. We used network construction methods to analyze the genetic architecture of gene expression in normal mouse skin in a cross between tumor-susceptible Mus musculus and tumor-resistant Mus spretus. We demonstrate that gene expression motifs representing different constituent cell types within the skin such as hair follicle cells, haematopoietic cells, and melanocytes are under separate genetic control. Motifs associated with inflammation, epidermal barrier function and proliferation are differentially regulated in mice susceptible or resistant to tumor development. The intestinal stem cell marker Lgr5 is identified as a candidate master regulator of hair follicle gene expression, and the Vitamin D receptor (Vdr) links epidermal barrier function, inflammation, and tumor susceptibility.

Description
Embryogenesis is tightly regulated by multiple levels of epigenetic systems such as DNA methylation, histone modification, and chromatin remodeling. DNA methylation patterns are erased in primordial germ cells and in the interval immediately following fertilization. Subsequent reprogramming occurs by de novo methylation and demethylation. Variance of DNA methylation patterns between different cell types is not well understood. Here, using methylated DNA immunoprecipitation and tiling array technology, we have comprehensively analysed DNA methylation patterns at proximal promoter regions in mouse embryonic stem (ES) cells, ES cell-derived early germ layers (ectoderm, endoderm and mesoderm) and four adult tissues (brain, liver, skeletal muscle and sperm). Most of the methylated regions in the three germ layers and in the three adult somatic tissues are shared in common. This commonly methylated gene set is enriched in germ cell associated genes that are generally transcriptionally inactive in somatic cells. We also compared DNA methylation patterns with global mapping of histone H3 lysine 4/27 trimethylation, and found that gain of DNA methylation correlates with loss of histone H3 lysine 4 trimethylation. Taken together, our findings indicate that differentiation from ES cells to the three germ layers is accompanied by an increase in the number of commonly methylated DNA regions and that these tissue-specific alterations are present for only a small number of genes. Our findings indicate that DNA methylation at the proximal promoter regions of commonly methylated genes act as an irreversible mark which fixes somatic lineage by repressing transcription of germ cell specific genes.
