Description
Autophagy is a homeostatic cellular process involved in the degradation of long-lived/damaged cellular components. The role of autophagy in adipogenesis is well recognized, but its role in mature adipocyte function is largely unknown. We show that the autophagy proteins Atg3 and Atg16L1 are required for proper mitochondrial function in mature adipocytes. In contrast to previous studies, we found that post-developmental ablation of autophagy causes peripheral insulin resistance independently of diet or adiposity. Finally, lack of adipocyte autophagy reveals a - cross talk between fat and liver mediated by lipid peroxide-induced Nrf2 signaling. Our data reveal a - role for autophagy in preventing lipid peroxide formation and their transfer in insulin-sensitive peripheral tissues Overall design: Epididymal adipose tissue from 4 WT and 4 Adiponectin-Cre Atg3f/f male mice fed chow diet

Description
In order to identify differentially expressed genes in developing seeds of Arabidopsis thaliana three different stages of seed development were analysed (9-10, 10-11 and 12-13 days after flower opening) for two Arabidopsis thaliana accessions, Col-0 and C24. For each stage and accession three biological replicates were analysed.

Description
Some aquaporins do not show a pronounced function as water diffusion facilitators but act as small molecule transport facilitators for substances such as urea, glycerol, boron or gases such as CO2 . Transcriptome analysis provided distinguishable, specific profiles for water stress or for conditions of increased or decreased CO2 concentrations
Publication Title
T-DNA insertion in aquaporin gene AtPIP1;2 generates transcription profiles reminiscent of a low CO2 response.

Description
We identify regulatory mechanisms that influence inflammation and metabolism during metabolic disease development. In addition to the other data represented in our paper, we performed RNA-seq to demonstrate a role for miR-146a, an anti-inflammatory miRNA, in regulating both inflammation and cellular metabolism during obesity. Overall design: Each sample represents pooled cells from three mice of the same genotype and treatment group. Samples were pooled before FACS to ensure sufficient cell numbers for sorting and RNA collection. WT or miR-146a-/- mice were treated with either high fat diet or normal chow diet for 14 weeks starting from 6 weeks of age. Mice were sacrificed and live, singlet CD45+ CD11b+ F4/80+ cells were sorted from the stromal vascular fraction of adipose tissue using FACS Aria. RNA was collected from the sorted cells via Qiazol/RNeasy Kit (Qiagen) and library preparation used Illumina TruSeq Stranded RNA Kit with Ribo-Zero Gold. RNA-seq was performed using Illumina HiSeq 50 cycle single-read sequencing version 4. Sequence alignment was performed through the University of Utah Bioinformatics Core Facility.

Description
The lungs are a frequent target of metastatic breast cancer cells, but the underlying molecular mechanisms are unclear. All existing data were obtained either using statistical association between gene expression measurements found in primary tumors and clinical outcome, or using experimentally derived signatures from mouse tumor models. Here, we describe a distinct approach that consists to utilize tissue surgically resected from lung metastatic lesions and compare their gene expression profiles with those from non-pulmonary sites, all coming from breast cancer patients.

Description
The Cdk7/cyclin H/mnage--trois 1 (MAT1) heterotrimer has proposed functions in transcription as the kinase component of basal transcription factor TFIIH and is activated in adult hearts by hypertrophic pathways. Using cardiac-specific Cre, we ablated MAT1 in myocardium. Despite reduced Cdk7 activity, MAT1-deficient hearts grew normally. However, fatal heart failure ensued at 6-8 weeks. By microarray profiling, quantitative RT-PCR, and Western blotting at 4 weeks, genes for energy metabolism were found to be suppressed selectively, including targets of peroxisome proliferator-activated receptor-gamma coactivator-1 (PGC-1). Cardiac metabolic defects were substantiated in isolated perfused hearts and isolated mitochondria. In culture, deleting MAT1 with Cre disrupted PGC-1 function: PGC-1 failed to activate PGC-1-responsive promoters and nuclear receptors, GAL4-PGC-1 was functionally defective, and PGC-1 likewise was deficient. PGC-1 was shown to interact with MAT1 and Cdk7, in co-precipitation assays. Thus, we demonstrate an unforeseen essential role for MAT1 in operation of the PGC-1 family of co-activators.
