Project description:In order to identify novel gene targets of vasopressin regulation in the renal medulla, we performed a cDNA microarray study on the inner medullary tissue of mice following a 48 hour water restriction protocol. Three renal medulla of 3 water restricted (WR) mice and three control mice (C) were hybridized against each other such that each WR sample was hybridized against each C sample.

Project description:This study in rats was designed to investigate whether whole rhye (WR) can influence the metabolism of n-3 and n-6 long-chain fatty acids (LCFA) and gut microbiota composition. For 12 weeks, rats were fed a diet containing either 50% WR or 50% refined rye (RR). Total bacterial DNA was extracted from fecal and cecal samples (n=5 per group). 16S PCR amplification was performed to assess the microbial diversity at the family level using the HuGChip. Amplified DNA was purified and labelled with either Cy3 or Cy5 dye and hybridized on the microarray.

Project description:Exercise improves brain function enhancing neuronal plasticity and cognitive enhancement. For voluntary resistance wheel running (RWR) exercise, with a load of 30% of body weight, we reported enhancement of neurogenesis and spatial memory associated with hippocampal brain-derived neurotrophic factor (BDNF) signaling compared to wheel running (WR) without a load (Lee et al., 2012; Lee et al., 2013). Despite these new evidences, mechanisms for RWR-induced improvement of hippocampal function remained to be clarified. In the present study, we have utilized the high-throughput DNA microarray approach to gain deep insight into molecular mechanisms underlying these changes that could be novel targets of RWR-induced hippocampal plasticity. To do so, whole genome (4x44K) high-density oligonucleotide microarrays were used to monitor the expression level of gene transcripts in the hippocampus of rats voluntary running for 4 weeks in comparison with sedentary animals. These rats showed a significant decrease in average running distance although average work levels immensely increased 12-fold in the RWR group, resulting in muscular adaptation for the fast-twitch plantaris muscle. DNA microarray analysis revealed that 122 (sedentary x WR) and 157 (sedentary x RWR) genes were up-regulated (> 1.5-fold change) as compared with 97 (sedentary x WR) and 467 (sedentary x RWR) down-regulated genes (< 0.75-fold change). Functional categorization using the Ingenuity Pathway Analysis (IPA) revealed expression pattern changes in the major categories of disease and disorders, molecular functions and physiological system development and function. Among these, RWR up-regulated genes such as NFATc1, AVPR1A and FGFR4, which are crucial role for neuronal development and its functions. The down-regulated inflammatory cytokines (IL1B, IL10, IL2RA, TNF) and chemokines (CXCL1, CXCL9, CXCL10, CCL2, CCL13, CCR4) might be important to neuronal dysfunction and vulnerability. Taken together, these gene candidates are suggested to play a critical role in hippocampal plasticity. This is a first study presenting not only new information into the voluntary RWR influenced transcriptome in the rat hippocampus, but also provides a hypothesis for the RWR influenced enhancement in brain function. 10-week-old male Wistar rats were randomly allocated to three groups: (1) housed in standard cages and used as non-active controls (sedentary, n = 10), (2) wheel running with no resistance (WR, n = 8), and (3) housed in cages with resistance running wheels with an adjustable resistance (RWR, n = 8). Rats of both running wheel groups (WR and RWR) were housed individually and had free access to a specially designed running wheel apparatus for 24 h/day. Between 08:00 and 12:00 on the day after the final day of exercise, the animals were immediately decapitated using a guillotine. The hippocampi were rapidly dissected, snap frozen in liquid nitrogen and stored at —80°C prior to further analysis. The deep-frozen hippocampi were transferred to a precooled (in liquid nitrogen) mortar and ground with a pestle to a very fine powder with liquid nitrogen. Total RNA was extracted and validated followed by checking subsequently synthesized cDNA by RT-PCR. A rat 4x44K whole genome oligo DNA microarray chip was used for global gene expression analysis using the hippocampi. Fluorescently labeled targets of Sed, WR and RWR samples were hybridized to the same microarray slide with 60-mer probes. A flip labeling (dye swap or reverse labeling with Cy3 and Cy5 dyes) procedure was followed to nullify the dye bias associated with unequal incorporation of the two Cy dyes into cDNA. Briefly, to select differentially expressed genes, we identified genes that were up regulated in chip 1 (Cy3/Cy5 label for sedentary and WR, respectively) but down regulated in chip 2 (Cy3/Cy5 label for WR and sedentary, respectively) for the hippocampus. The same selection criteria were applied for chips 3-4 (sedentary and RWR). Hybridization and wash processes were performed according to the manufacturer’s instructions, and hybridized microarrays were scanned using an agilent microarray scanner. The functional and network analysis were generated through the use of IPA (Ingenuity® Systems, www.ingenuity.com). To validate gene changes in array data and test the BDNF signaling-related molecules and expression of select transcripts were determined by quantitative real-time RT-PCR.

Project description:As an important cold-water economic fish species, rainbow trout (Oncorhynchus mykiss) exhibits several intra-specific variation in skin pigmentation that can give rise to distinctive phenotypes, and wild-type rainbow trout with black skin (WR) and yellow mutant rainbow trout with yellow skin (YR) are the major two types in the farms, whose distinct skin colors make them suitable model for elucidating the skin pigmentation process. Skin color as a key indicator for selection in rainbow trout farming as well as has a strong visual impact on the consumer when rainbow trout are marketed. Previously, extensive studies have been conducted on skin color in rainbow trout, including the observation of skin spots and the expression analysis of some important pigment genes. However, up to date, no studies have systematically examined the molecular regulation mechanism of skin color difference between WR and YR through a high throughput method. Therefore, the aim of this study was to reveal the molecular regulation mechanism of skin color difference between these two strains at the mRNA and miRNA transcriptome level, and candidate genes, miRNAs and miRNA-mRNA pairs that may be responsible for rainbow trout albinism were obtained.
