Affymetrix Mouse Genome 430A 2.0 Array (mouse430a2)
Description
Total RNA samples from Vax2 knockout mouse eyes (at least two biological replicates) were profiled by gene expression. As control we used total RNA from wild type eyes. The analysis was carried out at five different developmental stages: E10.5, E12.5, E16.5, P8, and P60.

Description
Predicting the impact of cis-regulatory sequence on gene expression is a foundational challenge for biology. We combine polysome profiling of hundreds of thousands of randomized 5' UTRs with deep learning to build a predictive model that relates human 5' UTR sequence to translation. Together with a genetic algorithm, we use the model to engineer new 5? UTRs that accurately target specified levels of ribosome loading, providing the ability to tune sequences for optimal protein expression. We show that the same approach can be extended to chemically modified RNA, an important feature for applications in mRNA therapeutics and synthetic biology. We test 35,000 truncated human 5' UTRs and 3,577 naturally-occurring variants and show that the model accurately predicts ribosome loading of these sequences. Finally, we provide evidence of 47 SNVs associated with human diseases that cause a significant change in ribosome loading and thus a plausible molecular basis for disease. Overall design: Polysom profiling and sequencing was performed using a library of 300,000 randomized 5' UTR 50-mers with eGFP used as the CDS. Three RNA chemistries were tested: unmodified, pseudouridine, and 1-methylpseudouridine. These were performed in duplicate (6 samples total). A designed library that includes human 5' UTRs, SNVs, and sequences engineered with a genetic algorithm was used with the eGFP CDS (no duplicate). A second randomized library used mCherry as the CDS, also performed in duplicate.

Description
Genetic predisposition and environmental components contribute to an individuals non-alcoholic fatty liver disease (NAFLD) susceptibility. Therefore, we compared phenotypic variations of mouse strains extensively used in biomedical research during induction of high-fat diet (HFD)-mediated NAFLD and assessed transcriptional alterations in livers. In a time-resolved fashion we determined a wide spectrum of physiological parameters in C3HeB/FeJ (C3H), C57BL/6NTac, C57BL/6J, and 129P2/OlaHsd (129) males during a 7, 14, or 21 days HFD challenge and performed gene transcription analyses in steatotic livers.

Description
Handedness and language are two well-studied examples of asymmetrical brain function in humans. Approximately 90% of humans exhibit a right-hand preference, and the vast majority shows left-hemisphere dominance for language function. Although genetic models of human handedness and language have been proposed, the actual gene expression differences between cerebral hemispheres in humans remain to be fully defined. In the present study, gene expression profiles were examined in both hemispheres of three cortical regions involved in handedness and language in humans and their homologues in rhesus macaques: ventrolateral prefrontal cortex, posterior superior temporal cortex (STC), and primary motor cortex. Although the overall pattern of gene expression was very similar between hemispheres in both humans and macaques, weighted gene correlation network analysis revealed gene co-expression modules associated with hemisphere, which are different among the three cortical regions examined. Notably, a receptor-enriched gene module in STC was particularly associated with hemisphere and showed different expression levels between hemispheres only in humans.

Description
BACKGROUND. Dietary intake of saturated fat is a likely contributor to nonalcoholic fatty liver disease (NAFLD) and insulin resistance, but the mechanisms that initiate these abnormalities in humans remain unclear. We examined the effects of a single oral saturated fat load on insulin sensitivity, hepatic glucose metabolism, and lipid metabolism in humans. Similarly, initiating mechanisms were examined after an equivalent challenge in mice.

Acute dietary fat intake initiates alterations in energy metabolism and insulin resistance.

Description
Cardiac structural changes associated with dilated cardiomyopathy (DCM) include cardiomyocyte hypertrophy and myocardial fibrosis. Connective Tissue Growth Factor (CTGF) has been associated with tissue remodeling and is highly expressed in failing hearts. To test if inhibition of CTGF would alter the course of cardiac remodeling and preserve cardiac function in the protein kinase C (PKC) mouse model of DCM. Transgenic mice expressing constitutively active PKC in cardiomyocytes develop cardiac dysfunction that was evident by 3 months of age, and that progressed to heart failure, cardiac fibrosis, and increased mortality. Beginning at 3 months of age, mice were treated with an antibody to CTGF (FG-3149) or non-immune IgG control antibody for an additional 3 months. CTGF inhibition significantly improved left ventricular (LV) systolic and diastolic function in PKC mice, and slowed the progression of LV dilatation. Using gene arrays and quantitative PCR, the expression of many genes associated with tissue remodeling were elevated in PKC mice, but significantly decreased by CTGF inhibition, however total collagen deposition was not attenuated. The observation of significantly improved LV function by CTGF inhibition in PKC mice suggests that CTGF inhibition may benefit patients with DCM.

In this survey we effectively combined transcriptomics, proteomics and targeted-metabolomics to analyse the temporal relationship of alterations in liver preceding and accompanying the development of HFD-mediated hepatic insulin resistance. To assess HFD-mediated alterations in physiological parameters, insulin sensitivity, and molecular adaptations in liver male C3HeB/FeJ mice treated with a high-fat diet (HFD) for 7, 14, or 21 days and compared to age- matched controls fed low-fat diet (LFD).
