Project description:We report the outcomes of next-generation sequencing (RNA-Seq) of guinea pig (Cavia porcellus) heart tissue and compare relative transcript abundances between fetus and adult.
Project description:We report the transcriptome profiles of guinea pig cytomegalovirus (Caviid betaherpesvirus 2 ; GPCMV) infected and uninfected cells. RNA was harvested at an early time post-infection. Data sets from a lung fibroblast cell line (JH4), primary amnion derived cells (1° AECs), and HPV16 E6/E7-transduced amniotic epithelial cells (AECD) is shared.
Project description:Non-alcoholic steatohepatitis (NASH) is a serious health challenge affecting millions worldwide, and research advances are restricted by the limited availability of preclinical models recapitulating the complex disease etiology and hepatic histopathology. Uniquely, the diet induced guinea pig model develops NASH with fibrosis resembling human histopathology however, no data is available depicting the guinea pig NASH transcriptome. We provide the first high throughput sequencing results on guinea pig NASH with advanced fibrosis. Transcriptomic profiles in guinea pig NASH clearly separated from controls, and pathways involved in fibrosis, inflammation and lipid metabolism were all highly regulated.
Project description:To investigate the effect of the dexamethasone-eluting electrode in the guinea pig cochlea, and compared the gene expression after 7 days insertion with that of a normal electrode or non-treated control by microarray.
Project description:To investigate the effect of the dexamethasone-eluting electrode in the guinea pig cochlea, and compared the gene expression after 7 days insertion with that of a normal electrode or non-treated control by microarray. Male Hartley guinea pigs (SLC, Shizuoka, Japan) with an age of seven weeks were used for the study. Three were implanted with normal electrodes while three others received a dexamethasone-eluting electrode. The cochleae from two animals, which did not undergo surgery. Seven days after electrode implantation the whole temporal bone was removed and placed into RNAlater solution (Ambion, Life Technologies Co., Grand Island, NY) to stabilize and protect cellular RNA. The whole cochlea was dissected out under a microscope and total RNA were extracted.
Project description:This is a combined SWATH database of early myopic guinea pig retina. The retinal tissues were divided into lens induced myopia 4 days group (4-day LIM) and control group; 5 individual animals (10 retinas) were included. The potential biomarkers and underlying biochemical pathways during early myopia could be investigated using SWATH based proteomics approach.
Project description:In this study we developed a guinea pig oligonucleotide microarray (GPOM) comprising of a total number of 45,220 features including 43,803 valid features from different mammalian species. These features are inclusive of 2971 newly annotated probes corresponding to 344 unique genes of guinea pig. As a case study, we utilized this array to examine the gene expression profile in guinea pig lungs in response to infection with Mycobacterium tuberculosis. Studying the global gene expression profile in guinea pigs allowed identification of the disease signature of pulmonary TB infection represented by several unique genes that are differentially regulated in this model. While, 1344 unique genes exhibited marked up regulation, 1856 genes were significantly down regulated. The newly developed tool not only finds its utility in studying the global gene expression profile associated with vaccination and/or M. tuberculosis infection in this highly useful animal model but would also be immensely useful in identification of new drug targets, testing of therapies, molecular genetic analysis for diseases other than tuberculosis as well. Genotypic Technology designed Custom Cavia porcellus 4x44k Gene Expression Array (Agilent-AMADID-019424) * In order to validate the GPOM developed in this study, we compared the gene expression profile of guinea pig lungs at 10 weeks post- M. tuberculosis infection with respect to that obtained from normal uninfected animals. To address this, guinea pigs were aerosol infected with M. tuberculosis, lungs were harvested at 10 weeks post-infection and RNA obtained from infected lungs was employed for cDNA synthesis and microarray hybridization. The gene expression was compared with the RNA sample obtained from the lungs of normal uninfected guinea pigs.
