Human respiratory syncytial virus is a major respiratory pathogen for which there are no suitable antivirals or vaccines. A better understanding of the host cell response to this virus may redress this problem. The present report concerns analysis of multiple independent biological replicates of control and 24 h infected lysates of A549 cells by two different proteomic workflows. One workflow involved fractionation of lysates by in-solution protein IEF and individual fractions were digested usin ...[more]

Response of A549 cells treated with Aspergillus fumigatus [WT-GC_vs_PrtT-GC]

Project description:Response of A549 cells treated with Aspergillus fumigatus wild type germinating conidia (WT_GC) or PrtT protease deficient mutant conidia (PrtT-GC) or inert acrylic 2-4 micron beads (Beads) for 8h Aspergillus fumigatus is the most commonly encountered mold pathogen of humans, predominantly infecting the respiratory system. Colonization and penetration of the lung alveolar epithelium is a key but poorly understood step in the infection process. This study focused on identifying the transcriptional and cell-signaling responses activated in A549 alveolar carcinoma cells incubated in the presence of A. fumigatus wild-type and ÎPrtT protease-deficient germinating conidia and culture filtrates (CF). Microarray analysis of exposed A549 cells identified distinct classes of genes whose expression is altered in the presence of germinating conidia and CF and suggested the involvement of both NFkB and MAPK signaling pathways in mediating the cellular response. Phosphoprotein analysis of A549 cells confirmed that JNK and ERK1/2 are phosphorylated in response to CF treatment in a protease-dependent manner. Inhibition of JNK or ERK1/2 kinase activity substantially decreased CF-induced cell damage, including cell peeling, actin-cytoskeleton damage, and reduction in metabolic activity and necrotic death. These results suggest that inhibition of MAPK-mediated host responses to treatment with A. fumigatus CF decreases cellular damage, a finding with possible clinical implications. 2 independent controls (uninfected A549 cells) as ctrl3_1-2, 2 independent treatments of A549 cells with wild-type A. fumigatus germinating conidia (WT_GC_1-2 ) , 2 independent treatments of A549 cells with inert acrylic beads (Beads 1-2), 3 independent treatments of A549 cells with A. fumigatus prtT mutant germinating conidia (PrtT-GC_1-3).

C4PR_LIV: N-terminomic analysis of SARS-CoV-2-infected ACE2-A549 cells (Unenriched)

Project description:Many events in viral infection are regulated through post-translational modification. In the case of positive-sense RNA viruses such as SARS-CoV-2 which encodes two viral proteases, proteolytic cleavage of both viral and cellular proteins is crucial for productive viral infection. In this work we study proteolysis in the context of SARS-CoV-2 infection of ACE2-A549 and Vero E6 cells, infected at a multiplicity of infection of 1, with samples harvested at 0,6,12 and 24h post-infection. Neo-N-termini and lysine residues were labelled at the protein level with TMTpro reagents prior to tryptic digestion. For unenriched samples, the trypsin-digested material was then fractionated offline, and analysed by LC-MS/MS for the study of total protein abundance over the infection timecourse. For enriched samples, unblocked neo-N-termini generated by tryptic digested were labelled with undecanal and depleted, yielding a sample enriched for blocked neo-N-termini (TMTpro, N-terminal acetylation, and pyroGlu). The enriched samples were similarly fractionated offline and analysed by LC-MS/MS. Please note this is one of several linked datasets. This dataset contains data from ACE2-A549 cells infected with SARS-CoV-2, prior to enrichment.
