Project description:A more in-depth exploration of gut functional aspects may be interesting in order to provide hints for action (e.g. dietary strategies) to favor gut balance maintenance (Sinha et al., 2017), given the important role of the intestine in development of possible metabolic diseases. A careful survey on the differential gene expression may help to scouting new interesting functions and identify potential markers for testing various experimental factors. The transcriptomes of the jejunum and cecum mucosae of 19 broiler chickens were compared. At slaughter age (day 42), on 38 birds, selected with a homogeneous body weight, jejunum and cecum mucosae were collected by gently scraping after tissues rinsing in PSB to remove residues of digesta, and immediately frozen in liquid nitrogen and then stored at -80°C. From both tissues, total RNA was extracted using GeneJET RNA Purification Kit (Thermo Scientific)
Project description:SPF leghorn chickens were infected with C. jejuni. The cecum were collected at 8h post infection for total RNA isolation. The significantly expressed microRNAs between infected and non-infected chickens were identified through Solexa sequencing technology.
Project description:White leghorn layers were infected with Salmonella Enteritidis. The cecum were collected at 7 days post infection for total RNA isolation. The significantly expressed microRNAs between infected and non-infected chickens were identified through Solexa sequencing technology.
