Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
CUGBP1 and MBNL1 are developmentally regulated RNA-binding proteins that are causally associated with myotonic dystrophy type 1. Using HITS-CLIP anlysis, we found CUGBP1 and MBNL1 preferentially bind to alternatively spliced introns and exons, as well as to the 3' UTRs.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
At present, substantial efforts are focused on the development of in vitro assays coupled with omics technologies for the identification of carcinogenic substances as an alternative to the classical 2-year rodent carcinogenicity bioassay. A prerequisite for the eventual regulatory acceptance of such assays, however, is the in vivo relevance of the observed in vitro findings.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Male Sprague-Dawley rats [Crl:CD(SD)IGS BR], weighing ~250 g at study initiation were obtained from Charles River Laboratories, Inc. (Wilmington, MA). Rats were housed singly in ventilated, stainless steel, wire-bottom hanging cages and fed non-certified Rodent Chow (Harlan Labs, Madison, WI) and water ad libitum and acclimated for at least 5 days after arrival. Rats were randomly assigned to various treatment groups (3 rats/group) and were dosed once daily by oral gavage with vehicle (0.2% hydroxypropylmethylcellulose at a dose volume of 10 ml/kg) or with 30, 100, or 200 mg/kg of A-998679. All rats were fasted overnight after their last dose, weighed and sacrificed under isoflurane anesthesia. Liver and small intestine (jejunum) were flash frozen in liquid nitrogen and stored at 80C until processing for gene expression profiling on the Affymetrix platform.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
For assessing the cancer-causing potential for humans of a chemical compound, the conventional approach is the use of the 2-year rodent carcinogenicity bioassay, thus alternatives such as in vitro toxicogenomics are highly desired. In the present study, the transcriptomics responses following exposure to genotoxic (GTX) and non-genotoxic (NGTX) hepatocarcinogens and non-carcinogens (NC) in five liver-based in vitro models, namely conventional and epigenetically-stabilized cultures of primary rat hepatocytes, the human hepatoma-derived HepaRG and HepG2 cell lines and the human embryonic stem cell-derived hepatocyte-like cells hES-Heps are examined and compared.

Description
Xenotransplantation holds the promise of providing an unlimited supply of donor organs for terminal patients with organ failure. The gal carbohydrate results in rejection of wild type pig grafts, however, chimerism established by expression of the GalT gene prior to transplantation in GalT knockout mice results in tolerance to Gal+ heart grafts.

- Affymetrix Rice Genome Array (rice)
Description
Twenty one day old seedlings of the mutant and WT grown in hydroponic culture in three replications were subjected to 25% PEG stress for one hour. The leaf samples of stressed and control seedlings were collected and preserved in liquid nitrogen for RNA isolation. Total RNA from four samples i.e. mutant control (MC), mutant stress (MS), Nagina22 control (NC) and Nagina22 stress (NS) was extracted by following the manufacturer‰۪s instructions provided with SV Total RNA isolation system Kit (PROMEGA, USA). All the steps starting from cRNA preparation to hybridization were conducted following the instructions of Affymetrix (AffymetrixGeneChip Expression Analysis Technical Manual). Chips were washed and stained in the Affymetrix Fluidics Station 450, and then scanned using the Affymetrix Gene Chip Scanner 3000. The cell intensity data files (.CEL) generated by the Gene Chip Operating Software (GCOS 1.2).

Description
Purpose: A super carbonate apatite (sCA) nanoparticle is an in vivo pH-sensitive delivery system for siRNA and microRNA. These carriers accumulate specifically in tumors, yet they cause no serious adverse events in mice and monkeys. Systemic administration of sCA incorporating siRNA and microRNA has demonstrated superb tumor suppressive effects in vivo. We recently observed that sCA could deliver abundant nucleic acids to the inflammatory sites in rheumatoid arthritis mouse model. Based on the success, we tried to examine whether sCA could deliver sufficient amounts of miRNA into the colorectum inflamed by dextran sodium sulfate (DSS) treatment. Methods: We performed a RNA sequencing analysis of the DSS-treated colon walls. DSS was administered for 4 days and sCA-miR-29a, sCA-miR-29b, sCA-NC-miR was injected on days 1, 2, 3. On day 4, colorectum was removed and the mRNA samples were subject to the RNA sequencing analysis. Results: RNA sequencing of the rectum samples showed a number of enhanced or reduced gene expression in DSS treated NC-miR group on day 4 compared to normal mice. Such tendency of upregulation or downregulation was also noted in DSS-treated NC-miR group on day 2. Comparison of DSS treated samples on day 4 among NC-miR, miR-29a and miR-29b groups, revealed that several gene expression related to the interferon pathway was reversed by miR-29a or miR-29b towards the normal controls. These include Stat1, Stat2, IRF7, IRF9, and IFIT1. Conclusions: Many molecules in the interferon signaling pathway were activated in DSS-induced colitis on day 4 and Stat1, Stat2, IRF7, IRF9, and IFIT1 were key molecules in the interferon related pathways. These findings suggest that sCA-miR-29a or sCA-miR-29b may inhibit type 1 IFN and type 2 IFN pathways which are otherwise activated by DSS treatment. Overall design: ?iR-29a and miR-29b, NC-miR loaded in sCA were systemically administered from the tail vein on the 1st, 2nd and 3rd days after the 2% DSS administration was started, and the rectum of the mouse was collected on the 4th day. RNA was extracted from the harvested colorectum. For these four conditions (n = 2) and normal mice (n = 2), ten samples were subjected to RNA sequencing.
