Affymetrix C. elegans Genome Array (celegans)
Description
We used microarray analysis to further our understanding of the mode of action of the well know caloric restriction mimetic rapamycin and the compound Allantoin first studied in the context of aging in this study. His work helps build on our understanding of potential caloric restriction mimetics predicted from our bioinformatic aproach of quering the Connectivity Map, a database of drug-induced gene expression profiles, using the transcriptional profile of CR to identify drugs that induce a similar or opposite gene expression profile.

Description
We generated h-hepatocyte chimeric mice with livers that were predominantly repopulated with h-hepatocytes in a h-growth hormone (GH)-deficient state. Using microarray profiles, comparison between h-hepatocytes from h-GH-treated and untreated mice identified 14 GH-up-regulated and four GH-down-regulated genes, including IGF-1, SOCS2, NNMT, IGFLS, P4AH1, SLC16A1, and SRD5A1, and FADS1 and AKR1B10, respectively.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Macrophage activation by bacterial lipopolysaccharides (LPS) is induced through Toll-like receptor 4 (TLR4). The synthesis and activity of TLR4 downstream signalling molecules modulates the expression of pro- and anti-inflammatory cytokines. To address the impact of post-transcriptional regulation on that process, we performed RIP-Chip analysis. Differential association of mRNAs with heterogeneous ribonucleoprotein K (hnRNP K), an mRNA-specific translational regulator in differentiating haematopoietic cells, was studied in non-induced and LPS-activated macrophages. Analysis of interactions affected by LPS revealed an enrichment of mRNAs encoding TLR4 downstream kinases and their modulators. We focused on transforming growth factor activated kinase-1 (TAK1), a central player in TLR4 signalling. HnRNP K interacts specifically with a sequence in the TAK1 mRNA 3' UTR in vitro. Silencing of hnRNP K does not affect TAK1 mRNA synthesis and stability, but enhances TAK1 mRNA translation, resulting in elevated TNF-alpha, IL-1beta and IL-10 mRNA expression. Our data suggest that the hnRNP K-3' UTR complex inhibits TAK1 mRNA translation in non-induced macrophages. LPS-dependent TLR4 activation abrogates translational repression and newly synthesised TAK1 initiates the inflammatory response of macrophages.

Translation control of TAK1 mRNA by hnRNP K modulates LPS-induced macrophage activation.

Description
Here, the effects of non-thermal low intensity pulsed ultrasound (LIPUS) on the gene expression in human lymphoma U937 cells were investigated using by an Affymetrix GeneChip system. Six hours after LIPUS treatment (0.3 W/cm2 for 1 min), apoptosis (143.8%, meanSD) with minimal cell lysis was observed. At 3 h post-treatment, LIPUS down-regulated 193 genes and up-regulated 201 genes by >1.5-fold.
