Project description:Comparing the host response of C57BL/6J mice to KEPI (ppp1r14c) knockouts in the same strain of mice. Groups of 10-week-old C57BL/6 mice or KEPI (ppp1r14c) knockout mice were infected with SARS MA15 at a dose of 10^5 PFU or mock infected. Mice were euthanized on days 4 and 7 post-infection to measure virus load and isolate samples for measurement of virus load, lung pathology, transcriptional analysis and proteomics analysis. Mock-infected animals were also harvested at each time point. Mice were weighed every 24 hours to measure general disease progression and any mouse approaching 30% weight loss was euthanized.

Groups of 10-week-old C57BL/6 mice or Tnfrsf1a/1b knockout mice were infected with SARS MA15 at a dose of 10^5 PFU or mock infected. Mice were euthanized on days 4 and 7 post-infection to measure virus load and isolate samples for measurement of virus load, lung pathology, transcriptional analysis and proteomics analysis.

Project description:Purpose of experiment was to perform transcriptomic analysis on C57Bl/6 mice infected with different doses of SARS CoV MA15 at 4 different days post infection.
Project description:Purpose of experiment was to perform transcriptomic analysis on C57Bl/6 mice infected with different doses of SARS CoV MA15 at 4 different days post infection. Twenty-week-old C57BL/6 mice were infected by intranasal instillation of 10^2, 10^3, 10^4 or 10^5 PFU of SARS CoV MA15 in 50 µl of PBS or mock-infected with PBS alone. At days 1, 2, 4 and 7 days post-infection, lungs were harvested and total RNA was isolated and subjected to microarray analysis. The experimental design was for 4- 5 mice/time point/dose and 3 time-matched mocks. The NIAID Systems Virology Center
