[PMID: 38670474 DOI: 10.1016/j.cellsig.2024.111190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 04/15/2024] [Accepted: 04/23/2024] [Indexed: 04/28/2024]
Abstract
Chronic obstructive pulmonary disease (COPD) is potentially fatal, and as society ages, its effects on human health are predicted to deteriorate. The potential function of m6A modifications within COPD has become a hot topic recently. This study was conducted to clarify the function and related mechanisms of the m6A methylation transferase ZC3H13 in COPD. The expression of m6A-associated protease and ITGA6 in COPD tissues was assessed using GEO data, qRT-PCR, and western blot. COPD models in cells and mice were established through cigarette smoke extract (CSE) and smoke exposure. Inflammatory marker levels were measured by ELISA, apoptosis by flow cytometry, and mRNA stability with Actinomycin D assay. m6A modification levels were checked by MeRIP-PCR. HE and Masson staining evaluated lung pathology, and alveolar lavage fluid analysis included total cell count and Giemsa staining. ZC3H13 and METTL3 were differentially expressed m6A regulators in COPD, with ZC3H13 being more significantly upregulated. Further analysis revealed the ZC3H13 expression-related differentially expressed genes (DEGs) functions were enriched in the immunoinflammatory pathway, indicating ZC3H13's involvement in COPD pathogenesis through inflammation, and immune responses. Knockdown studies in cellular and mouse models demonstrated ZC3H13's role in exacerbating COPD symptoms, including inflammation, apoptosis, and EMT, and its suppression led to significant improvements. The identification of ITGA6 as a target gene further elucidated the mechanism, showing that ZC3H13 enhances ITGA6 expression and mRNA stability through m6A modification, influencing bronchial epithelial cell inflammation and fibrosis. In conclusion, targeting ZC3H13/ITGA6 could be an underlying therapeutic approach for treating COPD.

Smoking-induced CCNA2 expression promotes lung adenocarcinoma tumorigenesis by boosting AT2/AT2-like cell differentiation. Cancer Lett 2024; 592:216922. [PMID: 38704137 DOI: 10.1016/j.canlet.2024.216922] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Revised: 04/25/2024] [Accepted: 04/26/2024] [Indexed: 05/06/2024]
Abstract
Lung adenocarcinoma (LUAD), a type of non-small cell lung cancer (NSCLC), originates from not only bronchial epithelial cells but also alveolar type 2 (AT2) cells, which could differentiate into AT2-like cells. AT2-like cells function as cancer stem cells (CSCs) of LUAD tumorigenesis to give rise to adenocarcinoma. However, the mechanism underlying AT2 cell differentiation into AT2-like cells in LUAD remains unknown. We analyze genes differentially expressed and genes with significantly different survival curves in LUAD, and the combination of these two analyses yields 147 differential genes, in which 14 differentially expressed genes were enriched in cell cycle pathway. We next analyze the protein levels of these genes in LUAD and find that Cyclin-A2 (CCNA2) is closely associated with LUAD tumorigenesis. Unexpectedly, high CCNA2 expression in LUAD is restrictedly associated with smoking and independent of other driver mutations. Single-cell sequencing analyses reveal that CCNA2 is predominantly involved in AT2-like cell differentiation, while inhibition of CCNA2 significantly reverses smoking-induced AT2-like cell differentiation. Mechanistically, CCNA2 binding to CDK2 phosphorylates the AXIN1 complex, which in turn induces ubiquitination-dependent degradation of β-catenin and inhibits the WNT signaling pathway, thereby failing AT2 cell maintenance. These results uncover smoking-induced CCNA2 overexpression and subsequent WNT/β-catenin signaling inactivation as a hitherto uncharacterized mechanism controlling AT2 cell differentiation and LUAD tumorigenesis.

Immun Inflamm Dis 2024; 12:e1231. [PMID: 38578019 PMCID: PMC10996381 DOI: 10.1002/iid3.1231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 02/26/2024] [Accepted: 03/14/2024] [Indexed: 04/06/2024] Open
Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a globally prevalent respiratory disease, and programmed cell death plays a pivotal role in the development of COPD. Disulfidptosis is a newly discovered type of cell death that may be associated with the progression of COPD. However, the expression and role of disulfidptosis-related genes (DRGs) in COPD remain unclear. METHODS The expression of DRGs was identified by analyzing RNA sequencing (RNA-seq) data in COPD. Further, COPD patients were classified into two subtypes by unsupervised cluster analysis to reveal their differences in gene expression and immune infiltration. Meanwhile, hub genes associated with disulfidptosis were screened by weighted gene co-expression network analysis. Subsequently, the hub genes were validated experimentally in cells and animals. In addition, we screened potential therapeutic drugs through the hub genes. RESULTS We identified two distinct molecular clusters and observed significant differences in immune cell populations between them. In addition, we screened nine hub genes, and experimental validation showed that CDC71, DOHH, PDAP1, and SLC25A39 were significantly upregulated in cigarette smoke-induced COPD mouse lung tissues and bronchial epithelial cells (BEAS-2B) treated with cigarette smoke extract. Finally, we predicted 10 potential small molecule drugs such as Atovaquone, Taurocholic acid, Latamoxef, and Methotrexate. CONCLUSION We highlighted the strong association between COPD and disulfidptosis, with DRGs demonstrating a discriminative capacity for COPD. Additionally, the expression of certain novel genes, including CDC71, DOHH, PDAP1, and SLC25A39, is linked to COPD and may aid in the diagnosis and assessment of this condition.

[PMID: 38378600 PMCID: PMC10880325 DOI: 10.1186/s12931-024-02736-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Accepted: 02/14/2024] [Indexed: 02/22/2024] Open
Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a common respiratory disease and represents the third leading cause of death worldwide. This study aimed to investigate miRNA regulation of Receptor for Advanced Glycation End-products (RAGE), a causal receptor in the pathogenesis of cigarette smoke (CS)-related COPD, to guide development of therapeutic strategies. METHODS RAGE expression was quantified in lung tissue of COPD patients and healthy controls, and in mice with CS-induced COPD. RNA-sequencing of peripheral blood from COPD patients with binding site prediction was used to screen differentially expressed miRNAs that may interact with RAGE. Investigation of miR-23a-5p as a potential regulator of COPD progression was conducted with miR-23a-5p agomir in COPD mice in vivo using histology and SCIREQ functional assays, while miR-23a-5p mimics or RAGE inhibitor were applied in 16-HBE human bronchial epithelial cells in vitro. RNA-sequencing, ELISA, and standard molecular techniques were used to characterize downstream signaling pathways in COPD mice and 16-HBE cells treated with cigarette smoke extract (CSE). RESULTS RAGE expression is significantly increased in lung tissue of COPD patients, COPD model mice, and CSE-treated 16-HBE cells, while inhibiting RAGE expression significantly reduces COPD severity in mice. RNA-seq analysis of peripheral blood from COPD patients identified miR-23a-5p as the most significant candidate miRNA interaction partner of RAGE, and miR-23a-5p is significantly downregulated in mice and cells treated with CS or CSE, respectively. Injection of miR-23a-5p agomir leads to significantly reduced airway inflammation and alleviation of symptoms in COPD mice, while overexpressing miR-23a-5p leads to improved lung function. RNA-seq with validation confirmed that reactive oxygen species (ROS) signaling is increased under CSE-induced aberrant upregulation of RAGE, and suppressed in CSE-stimulated cells treated with miR-23a-5p mimics or overexpression. ERK phosphorylation and subsequent cytokine production was also increased under RAGE activation, but inhibited by increasing miR-23a-5p levels, implying that the miR-23a-5p/RAGE/ROS axis mediates COPD pathogenesis via ERK activation. CONCLUSIONS This study identifies a miR-23a-5p/RAGE/ROS signaling axis required for pathogenesis of COPD. MiR-23a-5p functions as a negative regulator of RAGE and downstream activation of ROS signaling, and can inhibit COPD progression in vitro and in vivo, suggesting therapeutic targets to improve COPD treatment.

Abstract
BACKGROUND It is now understood that ferroptosis plays a significant role in the progression of chronic obstructive pulmonary disease (COPD) induced by cigarette smoke extract (CSE). However, the mechanisms underlying this relationship remain largely unclear. METHODS In this study, we established a COPD mouse model through exposure to cigarette smoke particulates, followed by H&E staining, analysis of bronchoalveolar lavage fluid, and immunohistochemistry assay. A549 cells were exposed to increasing concentrations of CSE, with the addition of the ferroptosis activator erastin or the inhibitor Fer-1. Cell viability, LDH (lactate dehydrogenase) release, inflammatory cytokines, total ROS (reactive oxygen species), and lipid ROS were measured using the corresponding assay kits. The acetylation level of GNPAT was determined through immunoprecipitation. We assessed the expression levels of molecules involved in plasmalogen biosynthesis (FAR1, AGPS, and GNPAT), GPX4, and SIRT4 using quantitative real-time PCR, western blot analysis, and immunofluorescence staining. RESULTS CSE-induced lung tissue damage was initially observed, accompanied by oxidative stress, ferroptosis, and increased plasmalogen biosynthesis molecules (FAR1, AGPS, and GNPAT). CSE also induced ferroptosis in A549 cells, resulting in reduced cell viability, GSH, and GPX4 levels, along with increased LDH, ROS, MDA (malondialdehyde) levels, oxidized lipids, and elevated FAR1, AGPS, and GNPAT expression. Knockdown of GNPAT mitigated CSE-induced ferroptosis. Furthermore, we found that CSE regulated the acetylation and protein levels of GNPAT by modulating SIRT4 expression. Importantly, the overexpression of GNPAT countered the inhibitory effects of SIRT4 on ferroptosis. CONCLUSIONS Our study revealed GNPAT could be deacetylated by SIRT4, providing novel insights into the mechanisms underlying the relationship between CSE-induced ferroptosis and COPD.

Respir Res 2023; 24:297. [PMID: 38007424 PMCID: PMC10675954 DOI: 10.1186/s12931-023-02598-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Accepted: 11/07/2023] [Indexed: 11/27/2023] Open
Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD), a chronic inflammatory lung disease, is a leading cause of morbidity and mortality worldwide. Prolonged cigarette smoking (CS) that causes irreversible airway remodeling and significantly reduces lung function is a major risk factor for COPD. Keratin15+ (Krt15+) cells with the potential of self-renewal and differentiation properties have been implicated in the maintenance, proliferation, and differentiation of airway basal cells; however, the role of Krt15 in COPD is not clear. METHODS Krt15 knockout (Krt15-/-) and wild-type (WT) mice of C57BL/6 background were exposed to CS for six months to establish COPD models. Krt15-CrePGR;Rosa26-LSL-tdTomato mice were used to trace the fate of the Krt15+ cells. Hematoxylin and eosin (H&E) and Masson stainings were performed to assess histopathology and fibrosis, respectively. Furthermore, lentivirus-delivered short hairpin RNA (shRNA) was used to knock down KRT15 in human bronchial epithelial (HBE) cells stimulated with cigarette smoke extract (CSE). The protein expression was assessed using western blot, immunohistochemistry, and enzyme-linked immunosorbent assay. RESULTS Krt15-/- CS mice developed severe inflammatory cell infiltration, airway remodeling, and emphysema. Moreover, Krt15 knockout aggravated CS-induced secretion of matrix metalloproteinase-9 (MMP-9) and epithelial-mesenchymal transformation (EMT), which was reversed by SB-3CT, an MMP-9 inhibitor. Consistent with this finding, KRT15 knockdown promoted MMP-9 expression and EMT progression in vitro. Furthermore, Krt15+ cells gradually increased in the bronchial epithelial cells and were transformed into alveolar type II (AT2) cells. CONCLUSION Krt15 regulates the EMT process by promoting MMP-9 expression and protects the lung tissue from CS-induced injury, inflammatory infiltration, and apoptosis. Furthermore, Krt15+ cells transformed into AT2 cells to protect alveoli. These results suggest Krt15 as a potential therapeutic target for COPD.

Chronic obstructive pulmonary disease (COPD) is a chronic disease associated with inflammation and structural changes in the airways and lungs, resulting from a combination of genetic and environmental factors. This interaction highlights significant genes in early life, particularly those involved in lung development, such as the Wnt signaling pathway. The Wnt signaling pathway plays an important role in cell homeostasis, and its abnormal activation can lead to the occurrence of related diseases such as asthma, COPD, and lung cancer. Due to the fact that the Wnt pathway is mechanically sensitive, abnormal activation of the Wnt pathway by mechanical stress contributes to the progression of chronic diseases. But in the context of COPD, it has received little attention. In this review, we aim to summarize the important current evidence on mechanical stress through the Wnt pathway in airway inflammation and structural changes in COPD and to provide potential targets for COPD treatment strategies.

Abstract
Tobacco smoke (TS) is the major cause of lung cancer. The abnormal proliferation and epithelial-mesenchymal transition (EMT) of lung cells promote occurrence and development of lung cancer. The p38 pathway intervenes in this cancer development. Hesperidin also serves a role in human health and disease prevention. The roles of p38 in TS-mediated abnormal cell proliferation and EMT, and the hesperidin intervention thereof are not yet understood. In the present study, it was demonstrated that TS upregulated proliferating cell nuclear antigen, vimentin and N-cadherin expression, whereas it downregulated E-cadherin expression, as assessed using western blotting and reverse transcription-quantitative PCR. Furthermore, it was observed that inhibition of the p38 pathway inhibit TS-induced proliferation and EMT. Hesperidin treatment prevented the TS-induced activation of the p38 pathway, EMT and cell proliferation in mouse lungs. The findings of the present study may provide insights into the pathogenesis of TS-related lung cancer.

Abstract
Cigarette smoke is a complex aerosol containing a large number of compounds with a variety of toxicity and carcinogenicity. Long-term exposure to cigarette smoke significantly increases the risk of a variety of diseases, including chronic obstructive pulmonary disease (COPD) and lung cancer. Epithelial–mesenchymal transition (EMT) is a unique biological process, that refers to epithelial cells losing their polarity and transforming into mobile mesenchymal cells, playing a crucial role in organ development, fibrosis, and cancer progression. Numerous recent studies have shown that EMT is an important pathophysiological process involved in airway fibrosis, airway remodeling, and malignant transformation of COPD. In this review, we summarized the effects of cigarette smoke on the development and progression of COPD and focus on the specific changes and underlying mechanisms of EMT in COPD induced by cigarette smoke. We spotlighted the signaling pathways involved in EMT induced by cigarette smoke and summarize the current research and treatment approaches for EMT in COPD, aiming to provide ideas for potential new treatment and research directions.

Abstract
Cigarette smoke (CS) mediates inflammation and epithelial-mesenchymal transition (EMT) in bronchial epithelial cells, contributing to airway remodeling in chronic obstructive pulmonary disease (COPD). Cross-talk between metabolic pathways and cell signaling has emerged as an important focus of research in the field of inflammation. Here, we established in vitro and in vivo models of CS-induced COPD to elucidate the role of pyruvate kinase M2 (PKM2), a glycolytic enzyme, in CS-induced airway remodeling. Exposure to CS significantly increased PKM2 expression in lung tissues of C57BL/6 mice and BEAS-2B cells, which positively related to the levels of airway inflammation and EMT. Administering PKM2 inhibitor shikonin attenuated CS-induced airway inflammation and EMT process. Moreover, knockdown of PKM2 by small-interfering RNA (siRNA) decreased the release of TNF-α and IL-8, ROS and reversed the CS extract (CSE)-induced changes of N-cadherin and E-cadherin in BEAS-2B cells. In CSE-treated cells, we also observed enhancement of PINK1/Parkin-mediated mitophagy, which were decreased by PKM2 siRNA. Furthermore, pretreatment with mitophagy inducer CCCP before CSE stimulation led to increased expressions of both nuclear and cytosolic PKM2, accompanied by reduction of TGF-β-induced factor homeobox 2 (TGIF2), a repressor of TGF-β1/smad pathway and EMT, while PKM2 knockdown restored the expression of TGIF2. Our results imply that CS induces PKM2 upregulation in airway epithelial cells, acting in synergism with PINK/Parkin-mediated mitophagy, which may initiate and exaggerate airway inflammation and EMT process. Further studies will be required to elucidate more molecular details and other pathways by which PKM2-mitophagy signaling regulates the effector function of airway epithelial.

Abstract
Colorectal cancer (CRC) constitutes a major public health problem due to the high rate of morbidity and mortality. Chemotherapy and immunotherapy are the major and promising strategies for cancer patients including CRC; nevertheless, chemoresistance and immune escape limit the final efficacy of above approaches. FERMT3 has been proved to exert the critical role in immune system and contradictive effects on cancer progression. In this study, bioinformatics database analysis and clinical specimen detection both corroborated the down-regulation of FERMT3 in CRC tissues and cells. Of interest, overexpression of FERMT3 suppressed CRC cell invasion and sensitized cells to 5-fluorouracil (5-FU) by reducing cell viability and increasing cell apoptosis and caspase-3 activity. Noticeably, FERMT3 up-regulation enhanced natural killer (NK) cells activation by increasing secretions of IFN-γ and TNF-α when NK cells were co-cultured with CRC cells. Importantly, up-regulation of FERMT3 promoted NK cell-mediated killing of CRC cells. Mechanically, FERMT3 inhibited the aberrant activation of Wnt/β-catenin signaling and the subsequent PD-L1 expression in CRC cells. Moreover, targeting PD-L1 suppressed CRC cell invasion, 5-FU resistance and NK cells-mediated tumor killing. Additionally, reactivating the Wnt/β-catenin signaling with a specific WNT agonist CAS 853220-52-7 overturned the efficacy of FERMT3 overexpression against CRC cell invasion, 5-FU chemoresistance and cell susceptibility to NK cell-mediated cytotoxicity. Thus, the current findings substantiate that FERMT3 elevation may attenuate CRC cell chemoresistance and NK cell-mediated immune response to tumor cells by inhibiting Wnt/β-catenin-PD-L1 signaling. Therefore, FERMT3 elevation may be a promising therapeutic approach to overcome chemoresistance and immune evasion in CRC. This article is protected by copyright. All rights reserved.

Abstract
Purpose This study aimed to identify candidate gene markers that may facilitate chronic obstructive pulmonary disease (COPD) diagnosis and treatment. Methods The GSE47460 and GSE151052 datasets were analyzed to identify differentially expressed mRNAs (DEmRs) between COPD patients and controls. DEmRs that were differentially expressed in the same direction in both datasets were analyzed for functional enrichment and for coexpression. Genes from the largest three modules were tested for their ability to diagnose COPD based on the area under the receiver operating characteristic curve (AUC). Genes with AUC > 0.7 in both datasets were used to perform regression based on the "least absolute shrinkage and selection operator" in order to identify feature genes. We also identified differentially expressed miRNAs (DEmiRs) between COPD patients and controls using the GSE38974 dataset, then constructed a regulatory network. We also examined associations between feature genes and immune cell infiltration in COPD, and we identified methylation markers of COPD using the GSE63704 dataset. Results A total of 1350 genes differentially regulated in the same direction in the GSE47460 and GSE151052 datasets were found. The genes were significantly enriched in immune-related biological functions. Of 186 modules identified using MEGENA, the largest were C1_ 6, C1_ 3, and C1_ 2. Of the 22 candidate genes screened based on AUC, 11 feature genes emerged from analysis of a subset of GSE47460 data, which we validated using another subset of GSE47460 data as well as the independent GSE151052 dataset. Feature genes correlated significantly with infiltration by immune cells. The feature genes GPC4 and RS1 were predicted to be regulated by miR-374a-3p. We identified 117 candidate methylation markers of COPD, including PRRG4. Conclusion The feature genes we identified may be potential diagnostic markers and therapeutic targets in COPD. These findings provide new leads for exploring disease mechanisms and targeted treatments.

Abstract
Animals have been indispensable in testing chemicals that can pose a risk to human health, including those delivered by inhalation. In recent years, the combination of societal debate on the use of animals in research and testing, the drive to continually enhance testing methodologies, and technology advancements have prompted a range of initiatives to develop non-animal alternative approaches for toxicity testing. In this review, we discuss emerging in vitro techniques being developed for the testing of inhaled compounds. Advanced tissue models that are able to recreate the human response to toxic exposures alongside examples of their ability to complement in vivo techniques are described. Furthermore, technology being developed that can provide multi-organ toxicity assessments are discussed.
