Single-cell transcriptomics reveals the pulmonary inflammation induced by inhalation of subway fine particles. JOURNAL OF HAZARDOUS MATERIALS 2024; 463:132896. [PMID: 37951166 DOI: 10.1016/j.jhazmat.2023.132896] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 10/28/2023] [Accepted: 10/28/2023] [Indexed: 11/13/2023]
Abstract
People generally take the subway and inevitably inhale the fine particles (PM2.5) on subway platforms. This study revealed whether and how subway PM2.5 causes lung inflammation. Herein, the pulmonary inflammatory response to subway PM2.5 was observed in mice, manifesting as the inflammatory cells infiltration and collagen deposition in tissue, inflammatory cytokine enhancement in bronchoalveolar lavage fluid and Toll-like receptors signal pathway activation in the lungs. Furthermore, single-cell RNA sequencing unearthed subway PM2.5-induced cell-specific responses in the lungs. Twenty immune subsets were identified by the molecular and functional properties. Specific cell populations of CD4+ T and γδ T cells were regarded as the predominant sources of pneumonitis induced by subway PM2.5. Moreover, we demonstrated that the lung inflammatory injury was significantly more attenuated in Rag1-/- mice lacking functional T cells and B cells than that in wild type mice. We proved the slight inflammation of lung tissue in Rag1-/- mice may be dependent on monocytes and neutrophils by activation of the intracellular molecular network. This is the first experimental study on subway PM2.5 causing pulmonary inflammatory damage. It will set an alarm for people who usually travel by subway and efficient measures to reduce PM2.5 should be developed in subway stations.

Dissecting Molecular Mechanisms Underlying Pulmonary Vascular Smooth Muscle Cell Dedifferentiation in Pulmonary Hypertension: Role of Mutated Caveolin-1 (Cav1 F92A)-Bone Marrow Mesenchymal Stem Cells. Heart Lung Circ 2018; 28:1587-1597. [PMID: 30262154 DOI: 10.1016/j.hlc.2018.08.002] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2018] [Revised: 07/29/2018] [Accepted: 08/14/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) is characterised by remodelling in vascular smooth muscles, and switching from contractile (differentiated) to synthetic (dedifferentiated) phenotype. This study aimed to investigate the effect of a mutated caveolin-1 (Cav1F92A) gene from bone marrow mesenchymal stem cells (rBMSCs) on phenotypic switching in the smooth muscle cells during PAH. METHODS Human pulmonary smooth muscle cells (HPASMCs) were treated with monocrotaline (MCT,1μM), and co-cultured with Cav1F92A gene modified rBMSCs (rBMSCs/Cav1F92A). The nitric oxide (NO) production, cell adhesion, cell viability and inflammatory cytokines expression in rBMSCs was measured to evaluate the survival rate of rBMSCs and the changes of inflammatory cytokines. The concentration of NO/cGMP (nitric oxide/Guanosine-3',5'-cyclic monophosphate), the tumour necrosis factor-alpha (TNF-α), transforming growth factor-beta1 (TGF-β1) mRNA, the expression of contractile smooth muscle cells (SMCs) phenotype markers (thrombospondin-1 and Matrix Gla protein, MGP), the synthetic SMCs phenotype markers (H-caldesmon and smooth muscle gene SM22 alpha, SM22α), cell migration and the morphological changes in rBMSCs/Cav1F92A co-cultured HPASMCs were investigated. RESULTS Cav1F92A increased NO concentration, cell adhesion, cell viability, anti-inflammatory cytokines interleukin-4 (IL-4), and interleukin-10 (IL-10), but decreased the inflammatory cytokines interleukin-1α (IL-1α), interferon-γ (INF-γ) and TNF-α expression in rBMSCs. rBMSCs/Cav1F92A activated the NO/cGMP, down-regulated TNF-α, TGF-β1, thrombospondin-1 and MGP expression, up-regulated SM22α and H-caldesmon expression, restored cell morphology, and inhibited cell migration in MCT treated HPASMCs. CONCLUSIONS rBMSCs/Cav1F92A inhibits switching from contractile to synthetic phenotype in HPASMCs. It also inhibits migration and promotes morphological restoration of these cells. rBMSCs/Cav1F92A may be used as a therapeutic modality for PAH.

Biomed Pharmacother 2018; 99:1-8. [PMID: 29324307 DOI: 10.1016/j.biopha.2018.01.038] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2017] [Revised: 12/16/2017] [Accepted: 01/03/2018] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Cell based therapy has been heralded as a novel, promising therapeutic strategy for cardiovascular diseases including pulmonary arterial hypertension (PAH). However, the low survival rate after transplantation due to cell death via anoikis is a major obstacle in stem cell therapy. Cells adhesion via Integrin alpha5beta1 (ITGA5B1) has a tendency to exert higher maximum forces. The present study aimed to evaluate the potential protective effect of ITGA5B1 on rat bone marrow mesenchymal stem cells (rBMSCs) from anoikis. METHODS Mononuclear cells were isolated by density gradient centrifugation with Ficoll, and rBMSCs cell surface markers were evaluated by flow cytometry. Osteogenic and adipocyte differentiation was determined by Alizarin Red S and Oil Red O staining respectively. The expression of Integrin A5 (ITGA5), Integrin B1 (ITGB1), eNOS and actived-caspase-3 mRNA or protein was confirmed by qPCR and western-blot. Cell adhesion, cell viability, anoikis and the migration of rBMSCs were also evaluated. Nitric oxide (NO) production was detected by the greiss assay. RESULTS Co-infected with Integrin A5 and B1 lentivirus to rBMSCs increased ITGA5 and ITGB1 mRNA and protein expression. ITGA5B1 enhanced the cell adhesion, cell viability, cell migration and NO production but reduced the cell anoikis in rBMSCs/ITGA5B1 groups. CONCLUSION Transduction of rat rBMSCs with ITGA5B1 lentivirus could prevent cell anoikis and increase NO production.

Oncol Lett 2017; 14:5591-5596. [PMID: 29113187 DOI: 10.3892/ol.2017.6908] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2017] [Accepted: 06/09/2017] [Indexed: 11/06/2022] Open
Abstract
Zinc-finger protein 750 (ZNF750) encodes a putative C2H2 zinc finger protein and is typically mutated or deleted in squamous cell carcinoma. The role of ZNF750 in oral squamous cell carcinoma (OSCC) remains unknown. The aim of the present study was to investigate the effects of ZNF750 overexpression in CAL-27 cells. Cell viability, and the expression of genes associated with proliferation, differentiation and the epithelial-mesenchymal transition were investigated in CAL-27 cells following ZNF750 overexpression, using Cell Counting kit-8, reverse transcription-quantitative polymerase chain reaction and western blot analysis, respectively. In addition, scratch wound, invasion and migration assays were performed. Cell viability, matrix metalloproteinase 28 expression, cyclin B1 expression and mesenchymal marker neural cadherin expression were decreased following ZNF750 overexpression compared with the control groups. ZNF750 overexpression induced the differentiation-associated genes late cornified envelope 3A and small proline-rich protein 1A and upregulated the expression of late epidermal differentiation factor Kruppel-like factor 4. Overexpression of ZNF750 in CAL-27 cells resulted in inhibition of cell invasion and migration. Taken together, these data suggest that ZNF750 may inhibit the metastasis of OSCC.
