The mRNA and microRNA (miR) transcriptome of lung neutrophils during S. pneumoniae pneumonia in wild type (WT) mice [mRNA]

Project description:These studies profiled the expression of mRNAs and microRNAs (miRs) in lung neutrophils in WT mice during S. pneumoniae pneumonia and performed in depth in silico analyses. Lung neutrophils were isolated 24 hours after intratracheal instillation of PBS or S. pneumoniae, and mRNAs and miRs differentially expressed (DE) between S. pneumoniae- and PBS-treated samples were identified using microarrays.

Analysis of mir-223 knockout cultured neutrophils versus wild-type cultured neutrophils, by ribosome profiling and mRNA-Seq

Project description:MicroRNAs (miRNAs) are endogenous ~22-nucleotide RNAs that mediate important gene-regulatory events by pairing to the mRNAs of protein-coding genes to direct their repression. Repression of these regulatory targets leads to decreased translational efficiency and/or decreased mRNA levels, but the relative contributions of these two outcomes have been largely unknown, particularly for endogenous targets expressed at low-to-moderate levels. Here, we use ribosome profiling to measure the overall effects on protein production and compare these to simultaneously measured effects on mRNA levels. For both ectopic and endogenous miRNA regulatory interactions, lowered mRNA levels account for most (≥84%) of the decreased protein production. These results show that changes in mRNA levels closely reflect the impact of miRNAs on gene expression and indicate that destabilization of target mRNAs is the predominant reason for reduced protein output.

Gene expression profiling of neutrophils and whole lung tissue from wildtype and Nrf2 null (Nfe2l2-/-) mice during S. pneumoniae pneumonia [neutrophils]

Project description:The transcription factor Nrf2 (gene symbol Nfe2l2) regulates the transcriptional response to oxidative stress and plays a critical protective role in the lungs. These studies tested the role of Nrf2 during pneumonia induced by Streptococcus pneumoniae (SP) at 24 hours in mice and identified Nrf2-dependent genes and pathways in lung tissue and in recruited neutrophils.
