Int J Mol Sci 2024; 25:1812. [PMID: 38339089 PMCID: PMC10855314 DOI: 10.3390/ijms25031812] [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: 11/15/2023] [Revised: 01/30/2024] [Accepted: 02/01/2024] [Indexed: 02/12/2024] Open
Abstract
Patients with pathological nipple discharge (PND) often undergo local surgical procedures because standard radiologic imaging fails to identify the underlying cause. MicroRNA (MiRNA) expression analysis of nipple fluid holds potential for distinguishing between breast diseases. This study aimed to compare miRNA expression levels between nipple fluids from patients with PND to identify possible relevant miRNAs that could differentiate between intraductal papillomas and no abnormalities in the breast tissue. Nipple fluid samples from patients with PND without radiological and pathological suspicion for malignancy who underwent a ductoscopy procedure were analyzed. We used univariate and multivariate regression analyses to identify nipple fluid miRNAs differing between pathologically confirmed papillomas and breast tissue without abnormalities. A total of 27 nipple fluid samples from patients with PND were included for miRNA expression analysis. Out of the 22 miRNAs examined, only miR-145-5p was significantly differentially expressed (upregulated) in nipple fluid from patients with an intraductal papilloma compared to patients showing no breast abnormalities (OR 4.76, p = 0.046), with a diagnostic accuracy of 92%. miR-145-5p expression in nipple fluid differs for intraductal papillomas and breast tissue without abnormalities and, therefore, has potential as a diagnostic marker to signal presence of papillomas in PND patients. However, further refinement and validation in clinical trials are necessary to establish its clinical applicability.

Abstract
Macrophage polarization is a dynamic process determining the outcome of various physiological and pathological situations through inducing pro-inflammatory responses or resolving inflammation via exerting anti-inflammatory effects. The miRNAs are epigenetic regulators of different biologic pathways that target transcription factors and signaling molecules to promote macrophage phenotype transition and regulate immune responses. Modulating the macrophage activation, differentiation, and polarization by miRNAs is crucial for immune responses in response to microenvironmental signals and under various physiological and pathological conditions. In term of clinical significance, regulating macrophage polarization via miRNAs could be utilized for inflammation control. Also, understanding the role of miRNAs in macrophage polarization can provide insights into diagnostic strategies associated with dysregulated miRNAs and for developing macrophage-centered therapeutic methods. In this case, targeting miRNAs to further regulate of macrophage polarization may become an efficient strategy for treating immune-associated disorders. The current review investigated and categorized various miRNAs directly or indirectly involved in macrophage polarization by targeting different transcription factors and signaling pathways. In addition, prospects for regulating macrophage polarization via miRNA as a therapeutic choice that could be implicated in various pathological conditions, including cancer or inflammation-mediated injuries, were discussed.

Abstract
Gastrointestinal (GI) carcinomas are a group of cancers affecting the GI tract and digestive organs, such as the gastric, liver, bile ducts, pancreas, small intestine, esophagus, colon, and rectum. MicroRNAs (miRNAs) are small functional non-coding RNAs (ncRNAs) which are involved in regulating the expression of multiple target genes; mainly at the post-transcriptional level, via complementary binding to their 3'-untranslated region (3'-UTR). Increasing evidence has shown that miRNAs have critical roles in modulating of various physiological and pathological cellular processes and regulating the occurrence and development of human malignancies. Among them, miR-145 is recognized for its anti-oncogenic properties in various cancers, including GI cancers. MiR-145 has been implicated in diverse biological processes of cancers through the regulation of target genes or signaling, including, proliferation, differentiation, tumorigenesis, angiogenesis, apoptosis, metastasis, and therapy resistance. In this review, we have summarized the role of miR-145 in selected GI cancers and also its downstream molecules and cellular processes targets, which could lead to a better understanding of the miR-145 in these cancers. In conclusion, we reveal the potential diagnostic, prognostic, and therapeutic value of miR-145 in GI cancer, and hope to provide new ideas for its application as a biomarker as well as a therapeutic target for the treatment of these cancer.

J Control Release 2023; 354:45-56. [PMID: 36586671 DOI: 10.1016/j.jconrel.2022.12.053] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 12/24/2022] [Accepted: 12/26/2022] [Indexed: 01/02/2023]
Abstract
Extracellular vesicles (EVs) are nano-sized carriers that reflect the parent cell's information and are known to mediate cell-cell communication. In order to overcome the disadvantages of mesenchymal stem cells (MSCs) in cell therapy, such as unexpected differentiation leading to tumorization, immune rejection, and other side effects, EVs derived from MSCs (MSC-EVs) with the tissue regenerative function have been studied as new cell-free therapeutics. However, therapeutic applications of EVs require overcoming several challenges. First, the production efficiency of MSC-EVs should be increased at least as much as the quantity of them are required to their clinical application; second, MSC-EVs needs to show various functionality further, thereby increasing tissue regeneration efficiency. In this study, we treated tauroursodeoxycholic acid (TUDCA), a biological derivative known to regulate cholesterol, to MSCs and investigated whether TUDCA treatment would be able to increase EV production efficiency and tissue regenerative capacity of EVs. Indeed, it appears that TUDCA priming to MSC increases the yield of MSC-EVs >2 times by reducing the cellular cholesterol level in MSCs and increasing the exocytosis-related CAV1 expression. Interestingly, it was found that the EVs derived from TUDCA-primed MSCs (T-EV) contained higher amounts of anti-inflammatory cytokines (IL1RN, IL6, IL10, and IL11) and osteogenic proteins (ALP, RUNX2, BMP2, BMPR1, and BMPR2) than those in control MSC-EVs (C-EV). Besides, it was shown that T-EV not only regulated M1/M2 macrophages differentiation of monocytes, also effectively increased the osteogenic differentiation of MSCs as well as bone tissue regeneration in a bone defect rat model. Based on these results, it is concluded that TUDCA treatment to MSC as a new approach endows EV with high-yield production and functionality. Thus, we strongly believe T-EV would be a powerful therapeutic material for bone tissue regeneration and potentially could be expanded to other types of tissue regeneration for clinical applications.

Abstract
Biomaterials are one of efficient treatment options for tissue defects in regenerative medicine. Compared to synthetic materials which tend to induce chronic inflammatory response and fibrous capsule, extracellular matrix (ECM) scaffold materials composed of biopolymers are thought to be capable of inducing a pro-regenerative immune microenvironment and facilitate wound healing. Immune cells are the first line of response to implanted biomaterials. In particular, macrophages greatly affect cell behavior and the ultimate treatment outcome based on multiple cell phenotypes with various functions. The macrophage polarization status is considered as a general reflection of the characteristics of the immune microenvironment. Since numerous reports has emphasized the limitation of classical M1/M2 nomenclature, high-resolution techniques such as single-cell sequencing has been applied to recognize distinct macrophage phenotypes involved in host responses to biomaterials. After reviewing latest literatures that explored the immune microenvironment mediated by ECM scaffolds, this paper describe the behaviors of highly heterogeneous and plastic macrophages subpopulations which affect the tissue regeneration. The mechanisms by which ECM scaffolds interact with macrophages are also discussed from the perspectives of the ECM ultrastructure along with the nucleic acid, protein, and proteoglycan compositions, in order to provide targets for potential therapeutic modulation in regenerative medicine.

Abstract
Skeletal muscle dysfunction is a common comorbidity of chronic obstructive pulmonary disease (COPD), and the molecular mechanisms regarding to the pathogenesis of this disease have not been elucidated. In this study, a novel miR-145-5p was significantly upregulated in the serum collected from patients with COPD-associated muscle atrophy, in contrast with the normal participants. Then, we evidenced that silencing of miR-145-5p suppressed cell death and elongated cell survival during cell culture process. Consistently, upregulation of miR-145-5p induced cell apoptosis and restrain cell viability in the C2C12 cells, suggesting that miR-145-5p contributes to cell death. Further experiments evidenced that miR-145-5p decreased the expression levels of phosphorylated PI3K (p-PI3K), Akt (p-Akt) and mTOR (p-mTOR) to inactivate the PI3K/Akt/mTOR pathway, and this pathway was also reactivated by miR-145-5p ablation. Finally, we proved that the protective effects of miR-145-5p ablation were abrogated by co-treating cells with PI3K inhibitor LY294002. Taken together, we concluded that miR-145-5p promoted cell death to facilitate muscle dysfunctions via inactivating the PI3K/Akt/mTOR pathway.

Abstract
Ozone is a ubiquitous air pollutant that causes lung damage and altered functioning. Evidence suggests that proinflammatory macrophages contribute to ozone toxicity. Herein, we analyzed the role of extracellular vesicles (EVs) and microRNA (miRNA) cargo in ozone-induced macrophage activation. Exposure of mice to ozone (0.8 ppm, 3 h) resulted in increases in bronchoalveolar lavage fluid EVs, which were comprised predominantly of microvesicles (MVs). NanoFACS analysis revealed that MVs generated following both air and ozone exposure was largely from CD45+ myeloid cells; these MVs were readily taken up by macrophages. Functionally, MVs from ozone, but not air treated mice, upregulated mRNA expression of inflammatory proteins in macrophages including inducible nitric oxide synthase (iNOS), CXCL-1, CXCL-2, and interleukin (IL)-1β. The miRNA profile of MVs in bronchoalveolar lavage fluid (BALF) was altered after ozone exposure; thus, increases in miR-21, miR-145, miR320a, miR-155, let-7b, miR744, miR181, miR-17, miR-92a, and miR-199a-3p were observed, whereas miR-24-3p and miR-20 were reduced. Ingenuity pathway analysis revealed that these miRNAs regulate pathways that promote inflammatory macrophage activation, and predicted that let-7a-5p/let-7b, miR-24-3p, miR-21-5p, miR-17, and miR-181a-5p are key upstream regulators of inflammatory proteins. After ozone exposure, miR-199a-3p, but not precursor miR-199a-3p, was increased in lung macrophages, indicating that it is derived from MV-mediated delivery. Furthermore, lung macrophage mRNA expression of IL-1β was upregulated after administration of MVs containing miR-199a-3p mimic but downregulated by miR-199a-3p inhibitor. Collectively, these data suggest that MVs generated following ozone exposure contribute to proinflammatory macrophage activation via MV-derived miRNAs including miR-199a-3p. These findings identify a novel pathway regulating macrophage inflammatory responses to inhaled ozone.

Abstract
AIMS Atherosclerosis is the dominant pathologic basis of many cardiovascular diseases. Large genome-wide association studies have identified that single-nucleotide polymorphisms proximal to Krüppel-like factor 14 (KLF14), a member of the zinc finger family of transcription factors, are associated with higher cardiovascular risks. Macrophage dysfunction contributes to atherosclerosis development and has been recognized as a potential therapeutic target for treating many cardiovascular diseases. Herein, we address the biologic function of KLF14 in macrophages and its role during the development of atherosclerosis. METHODS AND RESULTS KLF14 expression was markedly decreased in cholesterol loaded foam cells, and overexpression of KLF14 significantly increased cholesterol efflux and inhibited the inflammatory response in macrophages. We generated myeloid cell-selective Klf14 knockout (Klf14LysM) mice in the ApoE-/- background for the atherosclerosis study. Klf14LysMApoE-/- and litter-mate control mice (Klf14fl/flApoE-/-) were placed on the Western Diet for 12 weeks to induce atherosclerosis. Macrophage Klf14 deficiency resulted in increased atherosclerosis development without affecting the plasma lipid profiles. Klf14-deficient peritoneal macrophages showed significantly reduced cholesterol efflux resulting in increased lipid accumulation and exacerbated inflammatory response. Mechanistically, KLF14 upregulates the expression of a key cholesterol efflux transporter, ABCA1 (ATP-binding cassette transporter A1), while it suppresses the expression of several critical components of the inflammatory cascade. In macrophages, activation of KLF14 by its activator, perhexiline, a drug clinically used to treat angina, significantly inhibited the inflammatory response and increased cholesterol efflux in a KLF14-dependent manner in macrophages without triggering hepatic lipogenesis. CONCLUSIONS This study provides insights into the anti-atherosclerotic effects of myeloid KLF14 through promoting cholesterol efflux and suppressing the inflammatory response. Activation of KLF14 may represent a potential new therapeutic approach to prevent or treat atherosclerosis.
