Description
MicroRNAs (miRNAs) repress the expression levels of genes by binding to mRNA transcripts, acting as master regulators of cellular processes. Differential expression of miRNAs has been linked to viral-associated diseases involving members of the hepacivirus, herpesvirus, and retrovirus families. In contrast, limited biological and molecular information has been reported on the potential role of cellular miRNAs in the lifecycle of influenza A viruses (infA). In this study, we hypothesize that elucidating the miRNA expression signatures induced by low-pathogenic swine-origin influenza A virus (S-OIV) pandemic H1N1 (2009) and highly pathogenic avian-origin (A-OIV) H7N7 (2003) infections could reveal temporal and strain-specific miRNA fingerprints during the viral lifecycle, shedding important insights into the potential role of cellular miRNAs in host-infA interactions. Using a microfluidic microarray platform, we profiled cellular miRNA expression in human A549 cells infected with S- and A-OIVs at multiple time-points during the viral lifecycle, including global gene expression profiling during S-OIV infection. Using target prediction and pathway enrichment analyses, we identified the key cellular pathways associated with the differentially expressed miRNAs and predicted mRNA targets during infA infection, including immune system, cell proliferation, apoptosis, cell cycle, and DNA replication and repair. By identifying the specific and dynamic molecular phenotypic changes (microRNAome) triggered by S- and A-OIV infection in human cells, we provide experimental evidence demonstrating a series of temporal- and strain-specific host molecular responses involving different combinatorial contributions of multiple cellular miRNAs. Our results also identify novel potential exosomal miRNA biomarkers associated with pandemic S-OIV and deadly A-OIV-host infection.

Description
To identify molecular effects of genistein on mRNA levels in prostate cancer, we compared gene expression profiles of genistein-treated tumors with placebo-treated samples. There were 628 probes that reached nominally significant p-values. The genes that were differentially expressed between genistein and placebo samples were involved in angiogenesis, apoptosis, epithelial to mesenchymal transition, and tumor progression. Gene enrichment analysis suggested that PTEN and PDGF were activated, while MYC, beta-estradiol, glucocorticoid receptor NR3C1, and interferon-gamma were repressed in response to genistein treatment. These findings highlight the effects of genistein on global changes in gene expression in prostate cancer and its effects on molecular pathways involved in prostate tumorigenesis.

Description
B16F1 cells are a good model to study cell motility and cytoskeletal organization. In our lab, a combination of microscopy and gene silencing was used to approach the problem. Having gene expression profiles for B16F1 would facilitate and support subsequent gene silencing by RNAi as well as potentially identify new molecular players.

Description
Elevated branched chain amino acids (BCAAs) are associated with obesity and insulin resistance. How long-term dietary BCAAs impact late-life health and lifespan is unknown. Here, we show that when dietary BCAAs are varied against a fixed, isocaloric macronutrient background, long-term exposure to high BCAA diets led to hyperphagia, obesity and reduced lifespan. These effects were not due to elevated BCAA per se or hepatic mTOR activation, but rather the shift in balance between dietary BCAAs and other AAs, notably tryptophan and threonine. Increasing the ratio of BCAAs to these AAs resulted in hyperphagia and was linked to central serotonin depletion. Preventing hyperphagia by calorie restriction or pair-feeding averted the health costs of a high BCAA diet. Our data highlight a role for amino acid quality in energy balance and show that health costs of chronic high BCAA intakes were not due to intrinsic toxicity; rather, to hyperphagia driven by AA imbalance. Overall design: 3 animals per sex per diet were used. Mice were fed one of four diets (all 19% total protein, 63% carbohydrate, 18% fat, total energy density 14 kJ/g) varying in BCAA content (BCAA200: twice BCAA content of control diet AIN93G; BCAA100: standard content of BCAAs; and BCAA50 and BCAA20: containing one half and one fifth of standard content of BCAAs), and either euthanized at 15 months of age or maintained for determination of lifespan.
