Newborn Sex-specific Transcriptome Signatures and Gestational Exposure to Fine Particles: Findings from the ENVIRONAGE Birth Cohort

ABSTRACT: We investigated sex-specific transcriptomic responses to gestational long- and short-term exposure to particulate matter with a diameter < 2.5 µm (PM2.5) in order to elucidate potential underlying mechanisms of action. Whole genome gene expression was investigated in cord blood of 142 mother-newborn pairs that were enrolled in the ENVIRONAGE birth cohort. Daily PM2.5 exposure levels were calculated for each mother’s home address using a spatial-temporal interpolation model in combination with a dispersion model to estimate both long- (annual average before delivery) and short- (last month of pregnancy) term exposure. We explored the association between gene expression levels and PM2.5 exposure, and identified modulated pathways by overrepresentation analysis and gene set enrichment analysis.

Fine particulate matter (PM2.5) induces microRNA-192–5p causing glomerular damage

Project description:To unravel changes in gene expression due to exposure to PM2.5, we performed bulk RNA-seq analyses of zebrafish larvae exposed to PM2.5 and controls. Among others, PM2.5 increased oxoglutarate alpha-ketoglutarate receptor 1a, nitric oxide synthase, arachidonate 5-lipoxygenase b, immunity-related GTPase family e1, sulfotransferase family 5A, and macrophage expressed 1. NADPH oxidase organizer 1a and NADPH oxidase 1 were upregulated due to PM2.5 exposure. Furthermore, protein tyrosine/serine/threonine phosphatase activity was decreased after exposure to PM2.5. GESA analysis showed that genes involved in proteasome complex formation, inflammatory and immune response, leucocyte-mediated cytotoxicity, peptidase activator activity protein folding, and apoptotic signaling were upregulated after exposure to PM2.5. These results indicate that PM2.5 exposure caused the activation of immune-inflammatory and oxidative stress pathways and lipid and metabolic dysregulation.

Single-cell gene expression profiles of mice lung tissue under PM2.5 exposure

Project description:Numerous epidemiological studies have demonstrated a significant association between PM2.5 exposure and pulmonary diseases. PM2.5 may contribute to epithelial injury and immune dysregulation in lung cells. In this study, we provide single-cell level gene expression profiles of mouse lungs under PM2.5 exposure, offering insights into the microenvironmental alterations and physiological responses induced by PM2.5.

Differential contribution of bone marrow derived-monocytes to the lung tissue resident alveolar macrophages and persistent lung inflammation with chronic air pollution exposure

Project description:Chronic exposure to ambient particulate matter <2.5µ (PM2.5) has been linked to cardiopulmonary disease. Tissue-resident (TR) alveolar macrophages (AΦ) are long lived, self-renew and critical to the health impact of inhalational insults. There is inadequate understanding of the impact of PM2.5 exposure on nature/time course of transcriptional responses and the proliferation/maintenance of AΦ including the contribution from bone marrow (BM) over chronic time periods. We investigated the effects of exposure to real-world concentrated PM2.5 or filtered air (FA) in chimeric (CD45.2/CD45.1) mice. Here, we show that PM2.5 exposure induces an influx of BM-derived monocytes to lungs at 4-weeks, with no contribution to TR-AΦ population. Chronic (32-weeks) PM2.5 exposure resulted in enhanced apoptosis (Annexin V+) and decreased proliferation (BrdU+) of TR-AΦ and presence of BM-AΦ in inflamed lungs. RNA-seq analysis of flow sorted TR-AΦ and BM-AΦ from 4 and 32-weeks exposed mice, revealed a unique time dependent pattern of differentially expressed genes, with PM2.5 exposure with a pro-inflammatory bias. PM2.5 exposure resulted in pulmonary fibrosis and reduced alveolar fraction which corresponded to protracted lung inflammation. Our findings suggest a time dependent PM2.5 entrainment of a BM-derived monocytes infiltration into PM2.5 exposed lungs with an inflammatory phenotype, that together with enhanced apoptosis of TR-AΦ and pro-inflammatory polarization may contribute to perpetuation of chronic inflammation and lung fibrosis.
