TWIST1 DNA methylation is a cell marker of airway and parenchymal lung fibroblasts that are differentially methylated in asthma (2020)
Journal Article
Clifford, R. L., Yang, C. X., Fishbane, N., Patel, J., MacIsaac, J. L., McEwen, L. M., …Hackett, T. L. (2020). TWIST1 DNA methylation is a cell marker of airway and parenchymal lung fibroblasts that are differentially methylated in asthma. Clinical Epigenetics, 12(1), Article 145. https://doi.org/10.1186/s13148-020-00931-4

© 2020 The Author(s). Background: Mesenchymal fibroblasts are ubiquitous cells that maintain the extracellular matrix of organs. Within the lung, airway and parenchymal fibroblasts are crucial for lung development and are altered with disease, but it...

Airway epithelial cell isolation techniques affect DNA methylation profiles with consequences for analysis of asthma related perturbations to DNA methylation (2019)
Journal Article
Clifford, R. L., Patel, J., MacIsaac, J. L., McEwen, L. M., Johnson, S. R., Shaw, D., …Kobor, M. S. (2019). Airway epithelial cell isolation techniques affect DNA methylation profiles with consequences for analysis of asthma related perturbations to DNA methylation. Scientific Reports, 9(1), 1-12. https://doi.org/10.1038/s41598-019-50873-y

The airway epithelium forms the interface between the inhaled environment and the lung. The airway epithelium is dysfunctional in asthma and epigenetic mechanisms are considered a contributory factor. We hypothesised that the DNA methylation profiles...

Altered DNA methylation is associated with aberrant gene expression in parenchymal but not airway fibroblasts isolated from individuals with COPD (2018)
Journal Article
Clifford, R. L., Fishbane, N., Patel, J., MacIsaac, J. L., McEwen, L. M., Fisher, A. J., …Knox, A. J. (2018). Altered DNA methylation is associated with aberrant gene expression in parenchymal but not airway fibroblasts isolated from individuals with COPD. Clinical Epigenetics, 10(1), https://doi.org/10.1186/s13148-018-0464-5

Background: Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease of the lungs that is currently the fourth leading cause of death worldwide. Genetic factors account for only a small amount of COPD risk, but epigenetic mechanisms, i...

The role of histone arginine methylation in gene expression of airway smooth muscle cells in asthma (2016)
Journal Article
Kaczmarek, K., Clifford, R. L., Patel, J., Shaw, D., Dowden, J., & Knox, A. (2016). The role of histone arginine methylation in gene expression of airway smooth muscle cells in asthma. Thorax, 71(Suppl3), A214-A215. https://doi.org/10.1136/thoraxjnl-2016-209333.379

Introduction and objectives: Asthma is estimated to affect at least 300 million people globally. About 25% of the patients do not respond to therapy; therefore we need to develop novel treatments. ASM cells have a crucial role in asthma, contributing... Read More about The role of histone arginine methylation in gene expression of airway smooth muscle cells in asthma.

Epigenetic dysregulation of interleukin 8 (CXCL8) hypersecretion in cystic fibrosis airway epithelial cells (2016)
Journal Article
Poghosyan, A., Patel, J. K., Clifford, R. L., & Knox, A. J. (2016). Epigenetic dysregulation of interleukin 8 (CXCL8) hypersecretion in cystic fibrosis airway epithelial cells. Biochemical and Biophysical Research Communications, 476(4), 431-437. https://doi.org/10.1016/j.bbrc.2016.05.140

Airway epithelial cells in cystic fibrosis (CF) overexpress Interleukin 8 (CXCL8) through poorly defined mechanisms. CXCL8 transcription is dependent on coordinated binding of CCAAT/enhancer binding protein (C/EBP)?, nuclear factor (NF)-?B, and activ...

CXCL8 histone H3 acetylation is dysfunctional in airway smooth muscle in asthma: Regulation by BET (2015)
Journal Article
Clifford, R. L., Patel, J. K., John, A. E., Tatler, A. L., Mazengarb, L., Brightling, C. E., & Knox, A. J. (2015). CXCL8 histone H3 acetylation is dysfunctional in airway smooth muscle in asthma: Regulation by BET. AJP - Lung Cellular and Molecular Physiology, 308(9), L962-L972. https://doi.org/10.1152/ajplung.00021.2015

© 2015 The American Physiological Society. Asthma is characterized by airway inflammation and remodeling and CXCL8 is a CXC chemokine that drives steroid-resistant neutrophilic airway inflammation. We have shown that airway smooth muscle (ASM) cells... Read More about CXCL8 histone H3 acetylation is dysfunctional in airway smooth muscle in asthma: Regulation by BET.
