Diagnostic and Prognostic Value of Three microRNAs in Environmental Asbestiform Fibers-Associated Malignant Mesothelioma. J Pers Med 2021; 11:jpm11111205. [PMID: 34834557 PMCID: PMC8618926 DOI: 10.3390/jpm11111205] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Revised: 11/08/2021] [Accepted: 11/11/2021] [Indexed: 12/17/2022] Open
Abstract
Fluoro-edenite (FE) is an asbestiform fiber identified in Biancavilla (Sicily, Italy). Environmental exposure to FE has been associated with a higher incidence of malignant mesothelioma (MM). The present study aimed to validate the predicted diagnostic significance of hsa-miR-323a-3p, hsa-miR-101-3p, and hsa-miR-20b-5p on a subset of MM patients exposed to FE and matched with healthy controls. For this purpose, MM tissues vs. nonmalignant pleura tissues were analyzed through droplet digital PCR (ddPCR) to evaluate differences in the expression levels of the selected miRNAs and their MM diagnostic potential. In addition, further computational analysis has been performed to establish the correlation of these miRNAs with the available online asbestos exposure data and clinic-pathological parameters to verify the potential role of these miRNAs as prognostic tools. ddPCR results showed that the three analyzed miRNAs were significantly down-regulated in MM cases vs. controls. Receiver operating characteristic (ROC) analysis revealed high specificity and sensitivity rates for both hsa-miR-323a-3p and hsa-miR-20b-5p, which thus acquire a diagnostic value for MM. In silico results showed a potential prognostic role of hsa-miR-101-3p due to a significant association of its higher expression and increased overall survival (OS) of MM patients.

Abstract
BACKGROUND The aim of this study is to identify miRNAs able to predict the outcomes in breast cancer patients after neoadjuvant chemotherapy (NAC). PATIENTS AND METHODS We retrospectively analyzed 24 patients receiving NAC and not reaching pathologic complete response (pCR). miRNAs were analyzed using an Illumina Next-Generation-Sequencing (NGS) system. RESULTS Event-free survival (EFS) and overall survival (OS) were significantly higher in patients with up-regulation of let-7a-5p (EFS p = 0.006; OS p = 0.0001), mirR-100-5p (EFS s p = 0.01; OS p = 0.03), miR-101-3p (EFS p = 0.05; OS p = 0.01), and miR-199a-3p (EFS p = 0.02; OS p = 0.01) in post-NAC samples, independently from breast cancer subtypes. At multivariate analysis, only let-7a-5p was significantly associated with EFS (p = 0.009) and OS (p = 0.0008). CONCLUSION Up-regulation of the above miRNAs could represent biomarkers in breast cancer.

Abstract
miR-101 is downregulated in various types of cancer, leading to the notion that miR-101 acts as a suppressor in cancer cell progression. The comprehensive mechanisms underlying the effects of miR-101 and the exact role of miR-101 dysregulations in esophagogastric tumors have not been fully elucidated. This review aims to summarize all current knowledge on the association between miR-101 expression and esophagogastric malignancies and to clarify the pathogenetic pathways and the possible prognostic and therapeutic role of miR-101 in those cancer types. miR-101 seems to play crucial role in esophageal and gastric cancer biology and tumorigenesis. It could also be a promising novel diagnostic and therapeutic target, as well as it may serve as a significant predictive biomarker in esophagogastric cancer.

Abstract
In hepatitis C virus (HCV)/human immunodeficiency virus (HIV) co‐infected patients, HIV enhances HCV replication and liver damage. Several microRNAs (miRNAs), active in pro‐fibrotic and inflammatory pathways, have been implicated in the pathogenesis of this phenomenon. However, these miRNAs have been tested only in explanted cirrhotic livers, when the liver damage has become chronic and irreversible. No data are available on the early phase of viral infection, such as early after liver transplantation (LT). In the present study, the expression of miR‐101, miR‐122, miR‐155, miR‐192, miR‐200c, miR‐338, and miR‐532 was determined by quantitative real‐time polymerase chain reaction in liver biopsies of HCV (n = 19) and HCV/HIV‐infected (n = 20) LT recipients, as well as in a control group (n = 18) of noninfected patients, transplanted for alcoholic cirrhosis. The timing of liver biopsy was 6 months post‐LT. None of the patients was treated with direct‐acting anti‐HCV drugs. All co‐infected recipients had suppressed HIV viral load. Grading and staging were assessed according to the Ishak Classification. HCV and HIV viral load were measured in the sera. miR‐101 (p = .03), miR‐122 (p = .012), and miR‐192 (p = .038) were significantly downregulated in HCV/HIV co‐infected and HCV mono‐infected recipients when compared with noninfected recipients, and such downregulation was more pronounced in co‐infected ones. Moreover, in co‐infected recipients but not in mono‐infected ones, miR‐101 inversely correlated with the peripheral HCV‐RNA levels (r = .41, p = .04) and miR‐122 inversely correlated with peripheral HCV‐RNA levels (r = .49, p = .03) and with the histological grading (r = .51, p = .02). In conclusion, as early as 6 months after LT, the presence of HIV‐HCV co‐infection enhanced a significant downregulation of certain miRNAs that showed a direct correlation with HCV viral load and liver inflammation.

Abstract
BACKGROUND Colorectal cancer (CRC) is still a leading cause of death worldwide. Recent studies have pointed to an important role of microRNAs in carcinogenesis. Several microRNAs are described as aberrantly expressed in CRC tissues and in the serum of patients. However, functional outcomes of microRNA aberrant expression still need to be explored at the cellular level. Here, we aimed to investigate the effects of microRNAs aberrantly expressed in CRC samples in the proliferation and cell death of a CRC cell line. METHODS We transfected 31 microRNA mimics into HCT116 cells. Total number of live propidium iodide negative (PI-) and dead (PI+) cells were measured 4 days post-transfection by using a high content screening (HCS) approach. HCS was further used to evaluate apoptosis (via Annexin V and PI staining), and to discern between intrinsic and extrinsic apoptotic pathways, by detecting cleaved Caspase 9 and 8, respectively. To reveal mRNA targets and potentially involved mechanisms, we performed microarray gene expression and functional pathway enrichment analysis. Quantitative PCR and western blot were used to validate potential mRNA targets. RESULTS Twenty microRNAs altered the proliferation of HCT116 cells in comparison to control. miR-22-3p, miR-24-3p, and miR-101-3p significantly repressed cell proliferation and induced cell death. Interestingly, all anti-proliferative microRNAs in our study had been previously described as poorly expressed in the CRC samples. Predicted miR-101-3p targets that were also downregulated by in our microarray were enriched for genes associated with Wnt and cancer pathways, including MCL-1, a member of the BCL-2 family, involved in apoptosis. Interestingly, miR-101-3p preferentially downregulated the long anti-apoptotic MCL-1 L isoform, and reduced cell survival specifically by activating the intrinsic apoptosis pathway. Moreover, miR-101-3p also downregulated IL6ST, STAT3A/B, and MYC mRNA levels, genes associated with stemness properties of CRC cells. CONCLUSIONS microRNAs upregulated in CRC tend to induce proliferation in vitro, whereas microRNAs poorly expressed in CRC halt proliferation and induce cell death. We provide novel evidence linking preferential inhibition of the anti-apoptotic MCL-1 L isoform by miR-101-3p and consequent activation of the intrinsic apoptotic pathway as potential mechanisms for its antitumoral activity, likely due to the inhibition of the IL-6/JAK/STAT signaling pathway.

Insulin resistance (IR) and microRNAs (miRNAs), which regulate cell-to-cell communication between hepatocytes and hepatic stellate cells (HSCs), may intertwine in nonalcoholic fatty liver disease (NAFLD) pathogenesis. The aim of this study was to evaluate whether epigenetics and environmental factors interact to promote progressive NAFLD during IR. We examined the miRNA signature in insulin receptor haploinsufficient (InsR+/−) and wild-type (wt) HSCs by RNAseq (n = 4 per group). Then, we evaluated their impact in an IR-NASH (nonalcoholic steatohepatitis) model (InsR+/− mice fed standard or methionine choline deficient (MCD) diet, n = 10 per group) and in vitro. InsR+/− HSCs displayed 36 differentially expressed miRNAs (p < 0.05 vs. wt), whose expression was then analyzed in the liver of InsR+/− mice fed an MCD diet. We found that miR-101-3p negatively associated with both InsR+/− genotype and MCD (p < 0.05) and the histological spectrum of liver damage (p < 0.01). miR-101-3p was reduced in InsR+/− hepatocytes and HSCs and even more in InsR+/− cells exposed to insulin (0.33 µM) and fatty acids (0.25 mM), resembling the IR-NASH model. Conversely, insulin induced miR-101-3p expression in wt cells but not in InsR+/− ones (p < 0.05). In conclusion, IR combined with diet-induced liver injury favors miR-101-3p downregulation, which may promote progressive NAFLD through HSC and hepatocyte transdifferentiation and proliferation.

Abstract
BACKGROUND MicroRNA-101 (miR-101) is markedly downregulated in both hepatitis B virus-related liver cirrhosis and hepatocellular carcinoma (HCC). In this study, we aimed to investigate the effect and mechanism of miR-101 on hepatic stellate cell (HSC) activation and liver fibrosis. MATERIALS AND METHODS HSC LX-2 was treated with TGF-β1 and with or without miR-101 mimics. LX-2 vitality and proliferation, the expression of F-actin and mRNAs for α-SMA, collagen 1α1 (Col 1α1), and connective tissue growth factor 2 (CCN2) were measured. A 6-week intraperitoneal injection of carbon tetrachloride (CCl4) was used to induce experimental liver fibrosis in mice, which were treated using a miR-101 negative control or miR-101 agomir from the fourth week until the end of the experiment. Liver function, hepatic hydroxyproline, liver histopathology, collagen deposition, α-SMA, type I collagen (Col I) and the protein-expressions of p-PI3K, p-Akt and p-mTOR were measured. RESULTS MiR-101 significantly suppressed the increased LX-2 vitality and high accumulation of extracellular matrix (ECM) induced by TGF-β1. Exposure to CCl4 led to the impairment of liver function and disruption of normal hepatic parenchyma in mice, as well as obvious liver fibrosis indicated by elevated levels of hydroxyproline, α-SMA, and Col 1α1 in liver tissues. MiR-101 administration significantly improved liver function, relieved hepatic parenchyma damage, and reversed liver fibrosis by decreasing the accumulation of ECM components. Furthermore, miR-101 substantially downregulated the CCl4-increased p-PI3K, p-Akt, and p-mTOR in mouse liver. CONCLUSIONS MiR-101 has antifibrotic effects in experimental liver fibrosis, and downregulating the PI3K/Akt/mTOR signaling pathway may be one of its antifibrotic mechanisms.

Abstract
Small-cell lung cancer (SCLC) is a type of lung cancer with early metastasis, and high recurrence and mortality rates. The molecular mechanism is still unclear and further research is required. The aim of the present study was to examine the pathogenesis and potential molecular markers of SCLC by comparing the differential expression of mRNA and microRNA (miRNA) between SCLC tissue and normal lung tissue. A transcriptome sequencing dataset (GSE6044) and a non-coding RNA sequence dataset (GSE19945) were downloaded from the Gene Expression Omnibus (GEO) database. In total, 451 differentially expressed genes (DEGs) and 134 differentially expressed miRNAs (DEMs) were identified using the R limma software package and the GEO2R tool of the GEO, respectively. The Gene Ontology function was significantly enriched for 28 terms, and the Kyoto Encyclopedia of Genes and Genomes database had 19 enrichment pathways, mainly related to ‘cell cycle’, ‘DNA replication’ and ‘oocyte meiosis mismatch repair’. The protein-protein interaction network was constructed using Cytoscape software to identify the molecular mechanisms of key signaling pathways and cellular activities in SCLC. The 1,402 miRNA-gene pairs encompassed 602 target genes of the DEMs using miRNAWalk, which is a bioinformatics platform that predicts DEM target genes and miRNA-gene pairs. There were 19 overlapping genes regulated by 32 miRNAs between target genes of the DEMs and DEGs. Bioinformatics analysis may help to better understand the role of DEGs, DEMs and miRNA-gene pairs in cell proliferation and signal transduction. The related hub genes may be used as biomarkers for the diagnosis and prognosis of SCLC, and as potential drug targets.
