BACKGROUND: Identifying novel epigenetic signatures associated with serum immunoglobulin E (IgE) may improve our understanding of molecular mechanisms underlying asthma and IgE-mediated diseases.

METHODS: We performed an epigenome-wide association study using whole blood from Framingham Heart Study (FHS; n = 3,471, 46% females) participants and validated results using the Childhood Asthma Management Program (CAMP; n = 674, 39% females) and the Genetic Epidemiology of Asthma in Costa Rica Study (CRA; n = 787, 41% females). Using the closest gene to each IgE-associated CpG, we highlighted biologically plausible pathways underlying IgE regulation and analyzed the transcription patterns linked to IgE-associated CpGs …

Journal Articles

OBJECTIVE: to estimate the prevalence of polypharmacy, identify risk factors and examine related adverse outcomes in the US children with asthma.

DESIGN, SETTING AND PARTICIPANTS: This population-based, cross-sectional study included 1776 children with asthma from the 2011-2020 National Health and Nutrition Examination Surveys.

EXPOSURES: Polypharmacy is defined as taking ≥2 medications concurrently for ≥1 day over the past 30 days.

MAIN OUTCOMES AND MEASURES: (1) Weighted prevalence estimates of polypharmacy in children with asthma; (2) asthma attacks and emergency department (ED) visits.

RESULTS: The estimated prevalence of polypharmacy in the US children with asthma was 33.49% (95% CI 31.81% to …

Genetic And Non-Genetic Factors Affecting The Expression Of Covid-19-Relevant Genes In The Large Airway Epithelium, Silva Kasela, Victor E Ortega, Molly Martorella, Suresh Garudadri, Jenna Nguyen, Elizabeth Ampleford, Anu Pasanen, Srilaxmi Nerella, Kristina L Buschur, Igor Z Barjaktarevic, R Graham Barr, Eugene R Bleecker, Russell P Bowler, Alejandro P Comellas, Christopher B Cooper, David J Couper, Gerard J Criner, Jeffrey L Curtis, Meilan K Han, Nadia N Hansel, Eric A Hoffman, Robert J Kaner, Jerry A Krishnan, Fernando J Martinez, Merry-Lynn N Mcdonald, Deborah A Meyers, Robert Paine, Stephen P Peters, Mario Castro, Loren C Denlinger, Serpil C Erzurum, John V Fahy, Elliot Israel, Nizar N Jarjour, Bruce D Levy, Xingnan Li, Wendy C Moore, Sally E Wenzel, Charles Langelier, Prescott G Woodruff, Tuuli Lappalainen, Stephanie A Christenson

BACKGROUND: The large airway epithelial barrier provides one of the first lines of defense against respiratory viruses, including SARS-CoV-2 that causes COVID-19. Substantial inter-individual variability in individual disease courses is hypothesized to be partially mediated by the differential regulation of the genes that interact with the SARS-CoV-2 virus or are involved in the subsequent host response. Here, we comprehensively investigated non-genetic and genetic factors influencing COVID-19-relevant bronchial epithelial gene expression.

METHODS: We analyzed RNA-sequencing data from bronchial epithelial brushings obtained from uninfected individuals. We related ACE2 gene expression to host and environmental factors in the SPIROMICS cohort of smokers with …
