“…Some miRNAs are upregulated directly by CSE, like miR-21, which is induced by hypoxia-inducible factor 1-alpha (HIF-1α) ( 114 , 164 ), or others, like miR-664a-3p (targets FHL1 ), which is raised in lung tissue and peripheral blood mononuclear cells (PBMCs) from COPD patients, and in Beas-2B cells exposed to CSE ( 165 ). Exosomes are also carriers for pathogenic miRNAs, as CSE-treated HBECs produce exosomes carrying miR-21, inducing myofibroblast differentiation and increasing α-SMA and collagen-I through HIF-1α.…”

Chronic respiratory diseases (CRDs) are an important factor of morbidity and mortality, accounting for approximately 6% of total deaths worldwide. The main CRDs are asthma and chronic obstructive pulmonary disease (COPD). These complex diseases have different triggers including allergens, pollutants, tobacco smoke, and other risk factors. It is important to highlight that although CRDs are incurable, various forms of treatment improve shortness of breath and quality of life. The search for tools that can ensure accurate diagnosis and treatment is crucial. MicroRNAs (miRNAs) are small non-coding RNAs and have been described as promising diagnostic and therapeutic biomarkers for CRDs. They are implicated in multiple processes of asthma and COPD, regulating pathways associated with inflammation, thereby showing that miRNAs are critical regulators of the immune response. Indeed, miRNAs have been found to be deregulated in several biofluids (sputum, bronchoalveolar lavage, and serum) and in both structural lung and immune cells of patients in comparison to healthy subjects, showing their potential role as biomarkers. Also, miRNAs play a part in the development or termination of histopathological changes and comorbidities, revealing the complexity of miRNA regulation and opening up new treatment possibilities. Finally, miRNAs have been proposed as prognostic tools in response to both conventional and biologic treatments for asthma or COPD, and miRNA-based treatment has emerged as a potential approach for clinical intervention in these respiratory diseases; however, this field is still in development. The present review applies a systems biology approach to the understanding of miRNA regulatory networks in asthma and COPD, summarizing their roles in pathophysiology, diagnosis, and treatment.

“…The authors could not show the possible role of miR-212-5p in CSE-treated conditions. There is evidence that peripheral blood mononuclear cells and lung tissues obtained from COPD patients exhibited a higher level of miR-664a-3p compared to smokers [57]. Additionally, overexpression of miR-664a-3p in BEAS-2B cells negatively regulated FHL1 mRNA and protein levels.…”

The development of the lung involves a diverse group of molecules that regulate cellular processes, organ formation, and maturation. The various stages of lung development are marked by accumulation of small RNAs that promote or repress underlying mechanisms, depending on the physiological environment in utero and postnatally. To some extent, the pathogenesis of various lung diseases is regulated by small RNAs. In this review, we discussed miRNAs regulation of lung development and diseases, that is, COPD, asthma, pulmonary fibrosis, and pulmonary arterial hypertension, and also highlighted possible connotations for human lung health.After fertilization in the mouse, total miRNA in the two-cell-stage embryo was demonstrated to be significantly lower than the levels in one-cell zygote [15]. Notably, total miRNA in the four-cell-stage embryo was higher than the levels in the two-cell-stage embryo [15]. In the early mouse embryo, miR-127 was upregulated at E6.5 and E7.5 [16]. Overexpression of miR-127 in mouse embryonic stem cells, which differentiated into embryoid bodies, increased the mRNA levels of Gsc, Foxa2, and Brachyury (mesendoderm markers), but elicited no change in Pax6 and Otx2 (ectoderm markers) three days after transfection. Inhibition of miR-127 showed opposite regulation of Gsc, Foxa2, and Brachyury. miR-127, moreover, was suggested to control mesendoderm differentiation [16]. miR-326 regulated sonic hedgehog signaling by targeting Smo and Gli2 [17]. The inhibition of smoothened in cultured explanted E12 mouse lung resulted in the expansion of distal epithelium, and disruption of normal branching pattern and mesenchymal integrity [17]. Another study described the functional role of miR-142-3p in the mouse embryonic lung mesenchyme. The miRNA was shown to regulate adenomatous polyposis coli to further modulate Wnt signaling [18]. Taken together, miR-142-3p regulated the proliferation and differentiation of mesenchymal progenitors in the mouse embryonic lung [18].In the developing mouse lung, the level of miR-17 was stable (E11.5-E16.5), predominantly at the pseudoglandular stage, with higher epithelial levels at E12.5 [19]. Simultaneous knockdown of miR-17 and its paralogs, miR-20a and miR-106b, for 72 h in epithelial lung explants altered branching, even in FGF10-treated condition [19]. In the human fetal lung, miR-449a was upregulated at 18-20 weeks (canalicular stage), and in the mouse embryonic lung, miR-449a level was increased from E15.5 to E18.5 [20]. The inhibition of miR-449a in E16.5 mouse lung culture (end of pseudoglandular stage) increased the mRNA levels of Mycn and Sox9, and the protein levels of Ki-67 and SOX9 particularly in the distal epithelial region [20].Knockout of miR-26a-1/miR-26a-2 in the mouse promoted the formation of dilated lumens and aerated regions at the beginning of the canalicular stage (E16.5) of lung development [21]. Results at the saccular stage (E18.5) also indicated large lamellar bodies, and increased SP-A, SP-B, and SP-C protein levels in miR-26a knockout mice....

“…In COPD, miR-206 facilitated cell apoptosis in human pulmonary microvascular endothelial cells by the direct regulation of Notch3 and VEGFA; 26 miR-664a-3p overexpression was accountable for CSE-induced COPD through inhibiting FHL1. 27 Tang et al declared that miR-29b downregulation participated in the airway inflammation via upregulating BRD4. 28 In this chapter, miR-485-3p was discovered to have target relation with TLR4.…”

Background Smoking is the most common cause of chronic obstructive pulmonary disease (COPD), and the early diagnosis for COPD remains poor. Exploring the molecular mechanism and finding feasible biomarkers will be beneficial for clinical management of COPD. Circular RNAs (circRNAs) are noncoding RNAs that act as miRNA sponges to regulate the expression levels of genes, leading to the changes of cellular phenotypes and disease progression. CircRNA HECT domain and ankyrin repeat containing E3 ubiquitin protein ligase 1 (circ-HACE1) was abnormally expressed after the induction of cigarette smoke extract (CSE) in cell model. This study was performed to explore its function and mechanism in COPD. Methods Circ-HACE1, microRNA-485-3p (miR-485-3p) and toll-like receptor 4 (TLR4) detection was performed by quantitative real-time polymerase chain reaction (qRT-PCR). Cell viability and apoptosis/cell cycle were respectively examined using cell counting kit-8 (CCK-8) and flow cytometry. Inflammatory cytokines were determined by enzyme-linked immunosorbent assay (ELISA). Oxidative stress was evaluated through the measurement of malondialdehyde (MDA) and superoxide dismutase (SOD). The target binding analysis was conducted via dual-luciferase reporter assay. Western blot was employed for protein expression detection of TLR4. Results Circ-HACE1 was overexpressed in smokers or smokers with COPD and CSE upregulated circ-HACE1 expression in 16HBE cells. Knockdown of circ-HACE1 attenuated CSE-stimulated cell viability and cell cycle repression, as well as the enhancement of cell apoptosis, inflammatory response and oxidative stress. MiR-485-3p was a target of circ-HACE1. Circ-HACE1 regulated CSE-induced cell injury via targeting miR-485-3p. TLR4 was a downstream target of miR-485-3p, and miR-485-3p inhibited the CSE-induced cell damages by directly downregulating the level of TLR4. Circ-HACE1/miR-485-3p regulated TLR4 expression in CSE-treated 16HBE cells, and TLR4 overexpression also reversed all effects of si-circ-HACE1 on CSE-treated 16HBE cells. Conclusion These findings elucidated that circ-HACE1 contributed to the CSE-induced cell damages in COPD cell models via regulating TLR4 by acting as the sponge of miR-485-3p.
