Description
We previously found that mice with heterozygous knockout of the alpha-isoform of calcium/calmodulin-dependent protein kinase II (alpha-CaMKII HKO mice) show various dysregulated behaviors, including cyclic variations in locomotor activity (LA), suggesting that alpha-CaMKII HKO mice may serve as an animal model showing infradian oscillation of mood. We performed gene expression microarray analysis of dentate gyrus from alpha-CaMKII HKO mice. Mice were selected for the sampling such that their LA levels varied among the mice.

Description
To generate an unbiased view of changes to the retinal gene network in Neurog2 retinal mutants, we generated and compared the P2 transcriptomes from control, heterozygote and mutant mice. A pair of P2 retinas from each biologic replicate were used to produce libraries for high throughput sequencing (n = 5 biologic replicates/genotype). Reads were aligned with BWA and Bowtie programs to the mm10 genome. Aligned reads were then analyzed for differentially expressed transcripts using the CuffDiff program in the Galaxy online bioinformatics package (www.usegalaxy.org). Overall design: Total RNA from Neurog2CKO/CKO(wildtype; n = 5), Chx10Cre;Neurog2CKO/+(heterozygote; n = 5), and Chx10Cre;Neurog2CKO/CKO(mutant; n = 5) P2 retinas.

Description
White adipose tissue (WAT) is a highly active metabolic and endocrine organ, and its dysfunction links obesity to a variety of diseases, ranging from type 2 diabetes to cancer. The function of WAT is under the control of multiple cell signaling systems, including that of G protein-coupled receptors (GPCRs). Gs- and Gi-coupled receptors have been reported to regulate lipolysis, and Gq-coupled receptors stimulate glucose uptake in adipocytes. However, the roles of G12/13-coupled receptors in WAT are totally unknown. Here we show that lysophosphatidic acid receptor 4 (LPA4), an adipose cluster GPCR, selectively activates G12/13 proteins in adipocytes, and limits continuous remodeling and healthy expansion of WAT in mice. Under standard diet conditions, LPA4-knockout mice showed higher expression levels of mitochondrial biogenesis-related genes in WAT, along with higher production of adiponectin than control mice. In vitro studies have consistently demonstrated that the LPA4/Rho/Rho-kinase signaling pathway suppresses mRNA expression of mitochondrial biogenesis-related genes in adipocytes. In a diet-induced obesity model, LPA4-deficient mice showed metabolically healthy obese phenotypes, with continuous WAT expansion, and protection from WAT inflammation, hepatosteatosis, and insulin resistance. Given that GPCRs comprise the most successful class of drug targets, LPA4 would be a promising therapeutic target for obesity-related metabolic disorders.
