Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
The Her-2/Neu-positive mouse breast cancer cell line was serially co-cultured with minced brain, bone marrow, and lung tissue in an intravital microscopy chamber mounted on the dorsal skinfold of nude mice, alternating with growth in vitro. Gene expression analysis was performed on the cells grown in culture after sorting and further growth in vitro. Gene expression under these growth conditions differed in time and according to the co-cultivated organ tissue. This study reveals genes that are expressed by cells as they adapt differentially to various foreign tissue microenvironments, and may represent a paradigm to discover gene expression changes that occur immediately upon extravasation when cancer metastasizes.

Description
Based on preliminary data demonstrating that macrophages are critical regulators of Helicobacter pylori colonization and gastric pathology in mice, we sought to investigate how macrophages may serve as bacterial reservoirs of intracellular H. pylori. Overall design: BMDM were isolated from WT and PPARg-/- mice and cultured with M-CSF for 7 days to promote macrophage differentiation. Fully differentiation macrophages were challenged with H. pylori strains SS1 at an MOI of 10 for 15 minutes. Extracellular bacteria was then eliminated by gentamycin treatment. Cells were collected at 0, 60, 120, 240, 360 and 720 minutes post gentamycin treatment to ascertain whole transcriptome differential gene expression during infection.

Description
We sought to more precisely characterize the different alpha-synuclein (aSyn) 3’UTR mRNA species in normal and PD human brain. High-throughput, whole-transcriptome sequencing of the 3’UTR ends of polyadenylated mRNA transcripts (termed pA-RNAseq; see Methods) was performed on a cohort of 17 unaffected and 17 PD cerebral cortical tissue samples. This revealed 5 aSyn 3’UTR isoforms, with lengths of 290, 480, 560, 1070 and 2520 nt. Of these, the 560 nt and 2520 nt forms were predominant. The existence and relative preponderance of these species was further confirmed by Northern Blot. We next hypothesized, that aSyn 3’UTR selection might be altered in PD. Comparison of pA-RNAseq profiles from PD and unaffected cerebral cortex samples revealed an increase in the preponderance of the long 3’UTR species (>560 nt) relative to shorter species (<560 nt). Such a relative increase in aSynL was confirmed by Quantitative real-time RT-PCR (rt-qPCR) and appeared specific for PD, as the increase was also observed by comparison to RNA from amyotrophic lateral sclerosis patient samples. We note that the modified aSyn 3’UTR selection associated with PD patient tissue was detected in cerebral cortex tissue, which typically harbors pathological evidence of the disease process without frank cell loss; thus, this phenotype is unlikely to be a secondary consequence of neurodegeneration. Overall design: Comparison of 3''UTR ends of alpha-synuclein in PD and unaffected brain cortex

Description
VAAM stands for an amino acid mixture simulating the composition of Vespa, a hornet larval saliva. We conducted a comparative study on metabolism-regulatory roles of VAAM, casein-simulating amino acid mixture (CAAM), and pure water on murine hepatic and adipose tissue transcriptomes. Mice were orally fed VAAM solution ( 0.675 g/ kg BW = 2% of food-derived amino acids = 0.38% of total food energy/ day), CAAM solution ( 0.675 g / kg BW/ day) or water under ad libitum for five days. Hepatic transcriptome comparison of VAAM, CAAM and water-treated groups revealed a VAAM-specific regulation of the metabolic pathway, i.e., the down-regulation of glycolysis and fatty acid oxidation, and up-regulation of poly unsaturated fatty acid synthesis and glycogenic amino acids utilization in TCA cycle. Similar transcriptomic analysis of white and brown adipose tissues (WAT and BAT) suggested the up-regulation of phospholipid synthesis in WAT and the negative regulation of cellular processes in BAT. Because these coordinated regulations of tissue transcriptomes implicated the presence of upstream signaling common to these tissues, we conducted Ingenuity Pathways Analysis of these transcriptomes with the results that estrogenic and glucagon signals seemed to be activated in liver and WAT as well as beta-adrenergic signaling did in the three tissues by administration of VAAM. Our data provide a clue to understanding the role of VAAM in metabolic regulation of multiple tissues.
