ABSTRACT: To further identified miRNAs of BALB/c mouse lungs infected with A/Anhui/1/2013 (H7N9) (hereafter referred to as H7N9/AH1-PB2-627K(WT)) and mutant variants with PB2 amino acid substitutions (avian-like H7N9/AH1-PB2-627E and mammalian-adapted H7N9/AH1-PB2-627E/701N) , miRNA microarray was carried out.
Project description:The purpose is to obtain samples for mRNA, miRNA, proteomics, lipidomics, metabolomics, and histopathology analysis in mouse lung infected with WT A/Anhui/1/2013 (H7N9; 'AH1'), AH - NS1-103F/106M, and AH1 - 691 (ferret adapted virus).

Groups of 22-week-old C57BL/6 mice were infected with the H7N9 Influenza WT A/Anhui/1/2013 (H7N9; 'AH1'), AH - NS1-103F/106M, and AH1 - 691 (ferret adapted virus). Infections were done at 10^4 PFU or time-matched mock infected. Time points were 1, 2, 4 and 7 d.p.i. There were 5 animals/dose/time point. Lung samples were collected for virus load, transcriptional and proteomics analysis. Weight loss and animal survival were also monitored.

Project description:A novel avian-origin H7N9 influenza A virus (IAV) emerged in China in early 2013 causing mild to lethal human respiratory infections. H7N9 originated from multiple reassortment events between avian viruses and carries genetic markers of human adaptation. Determining whether H7N9 induces a host-response closer to human or avian IAV is important to better characterize this emerging virus. Here we compared the human lung epithelial cell response to infection with A/Anhui/01/13 (H7N9) or highly pathogenic avian-origin H5N1, H7N7, or human seasonal H3N2 IAV.

Here we compared the human lung epithelial cell response to infection with A/Anhui/01/13 (H7N9) or highly pathogenic avian-origin H5N1, H7N7, or human seasonal H3N2 IAV. Here, polarized confluent monolayers of Calu-3 cells were infected apically with the avian-origin IAVs A/Anhui/01/2013 (H7N9) [Anhui01], A/Netherland/219/2003 (H7N7) [NL219], A/Vietnam/1203/2004 (H5N1) [VN1203], or a human seasonal virus A/Panama/2007/1999 (H3N2) [Pan99] at an MOI of 1. Time-matched mocks were also included using the same cell stock as the rest of the samples. Culture medium (same as what the virus stock is in) was used for the mock infections. Quadruplicate wells were infected for each virus/timepoint. Measured timepoints were 3, 7, 12 and 24 hours post-inoculation and the RNA was used for transcriptional analysis via microarray.

Human Calu-3 cells were seeded at 1 x 10^6 cells per well on 6 well plates 2 days before infection. Prior to infection, washed cells 2 times with PBS, and then infected with a multiplicity of infection of 1. Infected samples were collected in quintuplet; time-matched mocks were collected in quintuplet in parallel with infected samples. Time points: 0, 7, 12 and 24 h post-infection
