Project description:To profile the expression of circulating microRNAs (miRNAs) of mice in experimental sepsis by cecal ligation and puncture (CLP), the whole blood samples were obtained from C57BL/6 mice at 4, 8, and 24 h following CLP for miRNA expression analysis using a miRNA array (The Mouse & Rat miRNA OneArray® v3). Briefly, mice were anesthetized with a combination of ketamine and xylazine as the anesthetic/analgesic agents and a midline abdominal incision was made. The cecum was mobilized, ligated in the middle of cecum below the ileocecal valve, punctured once with a 21 G needle, and a little stool was squeeze out of the cecum to induce polymicrobial peritonitis. The abdominal wall was closed in two layers. Sham-operated mice underwent the same procedure, including opening the peritoneum and exposing the bowel, but without ligation and needle perforation of the cecum.
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.
