High expression of oleoyl-ACP-hydrolase predicts mortality in patients hospitalized with avian A(H7N9) influenza

ABSTRACT: Although respiratory viral infections cause significant morbidity and mortality, it is still not fully clear why some individuals succumb to severe disease. In patients hospitalized with avian A(H7N9) influenza, we investigated early drivers underpinning hypercytokinemia and fatal disease. Our transcriptomics studies identified differential expression of 10 early host genes, defined by 16 probe sets, between patients who recovered and died. Seven probe sets were specific for the same host gene encoding for a key enzyme mediating free fatty acid production, oleoyl-ACP-hydrolase (OLAH). High olah transcript levels in fatal A(H7N9) patients were detected early after hospital admission and persisted until patients died. Conversely, patients who recovered had minimal olah transcript expression throughout their hospital stays.

Comparison of transcriptomic profiling between recovery and death group in H7N9 severe infection

Project description:Transcriptomic analysis confirms increased cellular activation in the patient recovery group. To identify molecular signatures correlated with H7N9 disease outcomes, we analysed the immune-related transcriptomes for PBMCs from 4 of the recovered (a73 d11, a134 d22, a20 d22, and a9 d21) and 4 of the fatal cases (a22 d22, a33 d21, a118 d19, and a131 d22). Total RNA was run on Affymetrix Human Gene ST 2.0 arrays and details of the probeset level normalisation and differential expression analysis are given in the Methods.

Whole blood gene expression profiles associated with mortality in community-acquired pneumonia

Project description:We aimed to examine the differences in the gene expression profile in peripheral blood at hospital admission between patients with community-acquired pneumonia (CAP) who died and survived during hospitalization. Whole blood samples for genome expression profile analysis were obtained within 24 hours of hospital admission. Gen set enrichment analysis (GSEA) identified gene sets positively enriched in the patients who survived, mainly related with interferon- alpha response, apoptosis, and sex hormones pathways. Similarly, GSEA identified gene sets positively enrichment for the patients who died (oxidative stress, endoplasmic reticulum stress, oxidative phosphorylation, and angiogenesis pathways).

Single-cell RNAseq of Human T lymphocyte derived from H7N9 infected patients

Project description:Comparing transcriptomes of CD8 T cells derived from a fatal H7N9 influenza infection with those derived from a patient that survived the infection. Specifically, CD38+ HLA-DR+ cells were sorted by flow cytometry at different sampling time-points, and the transcriptome was analysed using Smart-seq2.

Pilot Study on Differential Urine Proteomic Profile of Subjects with Community Acquired Acute Kidney Injury Who Recover Versus Those Who Do Not Recover Completely at 4 months after Hospital Discharge

Project description:Community acquired acute kidney injury (CAAKI) is a sudden structural damage and loss of kidney function in otherwise healthy individuals outside of hospital settings having high morbidity and mortality rates worldwide. Long-term sequelae of AKI involve an associated risk of progression to chronic kidney disease (CKD). Serum creatinine (SCr) the currently used clinical parameter for diagnosing AKI varies greatly with age, gender, diet and muscle mass. In the present study, we investigated the difference in urinary proteomic profile of subjects that recovered (R) and incompletely recovered (IR) from CAAKI, 4 months after hospital discharge. This study helped in identifying potential proteins and associated pathways that are either upregulated or downregulated at the time of hospital discharge in incompletely recovered CAAKI patients that can be further investigated to check for their exact role in the disease progression or repair.

Expression analysis of stable chronic obstructive pulmonary disease and acute exacerbation of chronic obstructive pulmonary disease

Project description:Investigation of whole genome gene expression level changes of the dynamic gene profiling of peripheral blood mononuclear cells (PBMCs) from patients with AECOPD) on day1, 3 and 10, compared to the normal people and stable COPD patients. A five chip study using total RNA recovered from Peripheral Blood Mononuclear Cell of Peripheral Blood.Evaluating the dynamic gene profiling of peripheral blood mononuclear cells (PBMCs) from patients with AECOPD) on day1, 3 and 10 after the hospital admission, to compared with healthy controls or patients with stable COPD. Slides were scanned at 5 μm/pixel resolution using an Axon GenePix 4000B scanner (Molecular Devices Corporation) piloted by GenePix Pro 6.0 software (Axon). Scanned images (TIFF format) were then imported into NimbleScan software (version 2.5) for grid alignment and expression data analysis. Expression data were normalized through quantile normalization and the Robust Multichip Average (RMA) algorithm included in the NimbleScan software. The Probe level (*_norm_RMA.pair) files and Gene level (*_RMA.calls) files were generated after normalization.

Transcriptomic characterization of the novel avian-origin influenza A (H7N9) virus: specific and intermediate host-response between avian (H5N1 and H7N7) and human (H3N2) viruses.

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, 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.
