Rieske Iron-Sulfur Protein Mediates Pulmonary Hypertension Following Nicotine/Hypoxia Co-Exposure
Am J Respir Cell Mol Biol. 2023 Nov 29. doi: 10.1165/rcmb.2023-0181OC. Online ahead of print.ABSTRACTThe high mortality of chronic obstructive pulmonary disease (COPD) patients may occur due to pulmonary hypertension (PH). These diseases are highly associated with cigarette smoke (CS) and its key component nicotine use. Here, we created a novel animal model of PH using nicotine (or CS) and hypoxia (N/H) co-exposure. This never-reported model showed a significant early-onset pulmonary vasoremodeling and PH. Using newly-generated complementary smooth muscle (SM)-specific Rieske iron-sulfur protein (RISP) gene knockout (KO) a...

GOLM1 Promotes Pulmonary Fibrosis through Upregulation of NEAT1
Am J Respir Cell Mol Biol. 2023 Nov 29. doi: 10.1165/rcmb.2023-0151OC. Online ahead of print.ABSTRACTIdiopathic pulmonary fibrosis (IPF) is a lethal progressive disease with elusive molecular mechanisms and limited therapeutic methods. Aberrant activation of fibroblasts is a central hallmark of lung fibrosis. Here we report that Golgi membrane protein 1 (GOLM1, also known as GP73 or GOLPH2), was elevated in both lungs of patients with pulmonary fibrosis and bleomycin (BLM)-induced pulmonary fibrotic mice. Loss of GOLM1 inhibited proliferation, differentiation, and extracellular matrix (ECM) deposition of fibroblasts, while...

Epigenetic Reprogramming Drives Epithelial Disruption in COPD
In this study, we sought to determine if epigenetic reprogramming of the cell-cell adhesion molecule E-cadherin, encoded by the CDH1 gene, disrupts epithelial integrity, and by reducing these epigenetic marks, we can restore epithelial integrity and rescue alveolar airspace destruction. We used differentiated normal and COPD-derived primary human airway epithelial cells, genetically manipulated mouse tracheal epithelial cells, and mouse and human precision-cut lung slices to assess the effects of epigenetic reprogramming. We show that the loss of CDH1 in COPD is due to increased DNA methylation site at the CDH1 enhancer D ...
