Transcriptomic profiling of guinea pigs with NASH and advanced fibrosis

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.

Comparative analysis of fasting effects on the cecum microbiome in three guinea pig breeds: Andina, Inti, and Peru.

Project description:Guinea pigs have historically been used as a food source and are also an important model for studying the human intestines. Fasting is the act of temporarily stopping the intake of food. This process can alter the microbiota of various animals. This study is the first to investigate the impact of fasting on the cecum microbiome of three guinea pig breeds. We investigated the impact of fasting on the microbiome population structure in the cecum of three guinea pig breeds. This was done by sequencing and analyzing the V4 hypervariable region of the 16S rRNA gene in bacterial communities found in cecum mucosa samples. To achieve this, we established two treatment groups (fasting and fed), for each of the three guinea pig breeds: Andina, Inti, and Peru. The study involved twenty-eight guinea pigs, which were divided into the following groups: Andina-fed (five), Andina-fasting (five), Inti-fed (four), Inti-fasting (five), Peru-fed (five), and Peru-fasting (four). The results indicated a significant difference in beta diversity between the treatment groups for the Peru breed (P-value = 0.049), but not for the treatment groups of the Andina and Inti breeds. The dominant phyla across all groups were Firmicutes and Bacteroidetes. We observed variations in the abundance of different taxa in the cecum microbiota when comparing the treatment groups for each breed. Additionally, there was a higher number of unique taxa observed in the fasting groups compared to the fed groups. We discovered that the genus Victivallis was the only one present in all fasting groups across all breeds. Despite the findings, the resilience of the gut microbiome was not challenged in all three breeds, which can lead to disruptive changes that may affect the overall maintenance of the cecum microbiome. Based on the observed differences in the treatment groups of the Peru breed, it can be suggested that fasting has a greater impact on this particular breed.

Development of oligonucleotide microarray to study global gene expression profile in guinea pigs in response to tuberculosis infection

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.
