Description
miR-34a and miR-34b/c genes are frequently epigenetically silenced in primary CRCs. However, the in vivo relevance of miR-34a/b/c for suppression of intestinal tumor formation has not been analyzed by genetic approaches. ApcMin/+ mice with deletion of the miR-34a and miR-34b/c genes were generated and analyzed. The mRNA expression profiles of intestinal adenomas with and without functional miR-34a/b/c genes were compared. Overall design: miR-34a/b/c deficient ApcMin/+ mice and wild-type ApcMin/+ mice were sacrificed at 18 weeks of age. 3 tumor RNA samples were obtained for each genotype; each tumor RNA sample represented a pool of 3 tumors isolated from the same mouse.

Description
We employ mRNA-seq to investigate transcriptome of Pum1-Knockout, Pum2-Knockout and WT conditons Overall design: In order to investigate whether Pum1 and Pum2 regulate their targets at their RNA levels, we used 1/10 of the samples from the Pum1 and Pum2 iCLIP experiments (four biological repeats of WT, P1KO, and P2KO neonatal brains) to extract total RNAs for RNA deep sequencing. And we also collected three Ndcko neonatal brains for RNA deep sequencing.

Description
Activity-dependent gene expression is central for sculpting neuronal connectivity in the brain. Despite the importance for synaptic plasticity, a comprehensive analysis of the temporal changes in the transcriptomic response to neuronal activity is lacking. In a genome wide survey we identified genes that were induced at 1, 4, 8, or 24 hours following neuronal activity in the hippocampus.

Description
The gut microbiota has been implicated in obesity and cardiometabolic diseases, although evidence in humans is scarce. We investigated how gut microbiota manipulation by antibiotics (7-day administration of amoxicillin, vancomycin, or placebo) affects host metabolism in 57 obese, prediabetic men. Vancomycin, but not amoxicillin, decreased bacterial diversity and reduced Firmicutes involved in short-chain fatty acid and bile acid metabolism, concomitant with altered plasma and/or fecal metabolite concentrations. Adipose tissue gene expression of oxidative pathways was upregulated by antibiotics, whereas immune-related pathways were downregulated by vancomycin. Antibiotics did not affect tissue-specific insulin sensitivity, energy/substrate metabolism, postprandial hormones and metabolites, systemic inflammation, gut permeability, and adipocyte size. Importantly, energy harvest, adipocyte size, and whole-body insulin sensitivity were not altered at 8-week follow-up, despite a still considerably altered microbial composition, indicating that interference with adult microbiota by 7-day antibiotic treatment has no clinically relevant impact on metabolic health in obese humans.

Description
Aging and neurodegeneration are often accompanied by a functionally impaired ubiquitin-proteasome system (UPS). In tauopathies and polyglutamine diseases a mutant form of Ubiquitin B, UBB+1, accumulates in disease-specific aggregates. UBB+1 mRNA is generated at low levels in vivo during transcription from the Ubiquitin B locus by molecular misreading. The resulting mutant protein has been shown to inhibit proteasome function. To elucidate causative effects and neuropathological consequences of UBB+1 accumulation, we used a UBB+1 expressing transgenic mouse line, that models UPS inhibition in neurons and exhibits behavioral phenotypes reminiscent of Alzheimers disease (AD). In order to reveal affected organs and functions, young and aged UBB+1 transgenic mice were comprehensively phenotyped for more than 240 parameters. This revealed unexpected changes in spontaneous breathing patterns and an altered response to hypoxic conditions. Our findings point to a central dysfunction of respiratory regulation in transgenic mice in comparison to wildtype littermate mice. Accordingly, UBB+1 was strongly expressed in brainstem regions of transgenic mice controlling respiration. These regions included, for example, the medial part of the nucleus of the tractus solitarius and the lateral subdivisions of the parabrachial nuclei. In addition, UBB+1 was also strongly expressed in these anatomical structures of AD patients (Braak stage #6) and was not expressed in non-demented controls. We conclude that long-term UPS inhibition due to UBB+1 expression causes central breathing dysfunction in a transgenic mouse model of AD. The UBB+1 expression pattern in humans is consistent with the contribution of bronchopneumonia as a cause of death in AD patients.

Description
To characterize the transcriptome of the transcription factor AP4 DLD-1 cells were infected with AP4 coding viruses for different periods of time. Adenovirus amplification and purification was performed as previously described (He et al., 1998). The minimal amount of virus needed to reach more than 90% infection efficiency was determined by monitoring GFP signals with fluorescence microscopy. DLD-1 cells were infected in serum-free medium with adenovirus for 3 hours. After removal an equal amount of medium containing 20% FBS was added.
