Abstract
MINCR (MYC-Induced Long Non-Coding RNA) is classified as an lncRNA. It has a significant correlation with MYC gene. MINCR has important roles in the carcinogenesis. It has been approved that this lncRNA can act as molecular sponge for miR-28-5p, miR-708-5p, miR-876-5p and miR-146a-5p. Dysregulated levels of MINCR has been observed in different types of cancer, especially hepatocellular carcinoma. In addition to malignant conditions, schizophrenia and neurodegenerative diseases such as Alzheimer's disease and amyotrophic lateral sclerosis are associated with dysregulation of expression patterns of MINCR. This review outlines MINCR molecular mechanisms of action in different disorders.

Abstract
Long non-coding RNAs (lncRNAs) play vital roles in regulating epigenetic mechanisms and gene expression levels, and their dysregulation is closely associated with a variety of diseases such as cancer. Several studies have demonstrated that lncRNAs are dysregulated during tumor progression. Recently, the MYC-induced long non-coding RNA MINCR, a newly identified lncRNA, has been demonstrated to act as an oncogene in different cancers, including gallbladder cancer, hepatocellular cancer, colorectal cancer, non-small cell lung cancer, oral squamous cell carcinoma, nasopharyngeal cancer, and glioma. Moreover, MINCR has been reported to act as a biomarker in the prognosis of patients with different cancers. In this review, we summarize and analyze the oncogenic roles of MINCR in a variety of human cancers in terms of its clinical significance, biological functions, cellular activities, and regulatory mechanism. Our analysis of the literature suggests that MINCR has potential as a novel biomarker and therapeutic target in human cancers.

Abstract
The purposes of this study are to explore the function and regulatory mechanism of a novel lncRNA MYC-Induced Long non-coding RNA (MINCR) in osteoarthritis (OA). The expression of lncRNA MINCR, miR-146a-5p, and bone morphogenetic protein receptor 2 (BMPR2), Sry-type high-mobility-group box 9 (SOX9), collagen type II alpha 1 (COL2A1), Aggrecan, metalloproteinase with thrombospondin motifs-4 (ADAMTS-4), Matrix metalloproteinase 3 (MMP3), MMP13, COL2A1, and Aggrecan were determined using quantitative real-time PCR (qRT-PCR), western blot, immunohistochemistry (IHC) and immunofluorescence (IF) in vitro and in vivo. And distribution and expression of MINCR were examined by fluorescence in situ hybridization (FISH). Cell proliferation and apoptosis were detected by cell counting kit-8 (CCK-8) assay, 5-Ethynyl-2'-deoxyuridine (EdU) staining, Annexin V-FITC/Propidium Iodide (PI), and Terminal Deoxynucleotidyl transferase-mediated dUTP Nick-End Labeling (TUNEL) staining in vitro and in vivo. The anterior cruciate ligament transection (ACLT) rat model was constructed to analyze the MINCR/miR-146a-5p/BMPR2 axis in vivo. The cartilage degeneration was determined by pathological staining with Hematoxylin and Eosin (H&E) and Safranin O staining. The binding relationship between MINCR and miR-146a-5p, and between miR-146a-5p and BMPR2 were determined by a dual-luciferase reporter gene, RNA Immunoprecipitation (RIP) assay, and RNA-pull down assays. Here, MINCR and BMPR2 were downregulated whereas miR-146a-5p was upregulated in OA cartilage tissues compared with control as well as IL-1β-induced chondrocytes compared with normal chondrocytes. Function experiments indicated that MINCR upregulation promoted cell proliferation and inhibited apoptosis and extracellular matrix (ECM)-degeneration. We also proved the binding relationship between MINCR and miR-146a-5p, and the BMPR2 acted as a target of miR-146a-5p. Mechanism analysis using rescue experiments in vitro and in vivo, MINCR silencing reversed the effects of miR-146a-5p downregulation in OA. Overexpression of miR-146a-5p also reversed the function of BMPR2 overexpression in OA. These data indicated that MINCR prevented OA progression via targeting miR-146a-5p to promote BMPR2 expression.

Abstract
The multitasking nature of lncRNAs allows them to play a central role in both physiological and pathological conditions. Often the same lncRNA can participate in different diseases. Specifically, the MYC-induced Long non-Coding RNA MINCR is upregulated in various cancer types, while downregulated in Amyotrophic Lateral Sclerosis patients. Therefore, this work aims to investigate MINCR potential mechanisms of action and its implications in cancer and neurodegeneration in relation to its expression levels in SH-SY5Y cells through RNA-sequencing approach. Our results show that MINCR overexpression causes massive alterations in cancer-related genes, leading to disruption in many fundamental processes, such as cell cycle and growth factor signaling. On the contrary, MINCR downregulation influences a small number of genes involved in different neurodegenerative disorders, mostly concerning RNA metabolism and inflammation. Thus, understanding the cause and functional consequences of MINCR deregulation gives important insights on potential pathogenetic mechanisms both in cancer and in neurodegeneration.

Abstract
BACKGROUND Inflammation plays an important role in the development of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). The long non-coding RNA (lncRNA) MINCR is closely related to inflammation injury. This study was performed to explore the protective effects and mechanisms of MINCR in lipopolysaccharide (LPS)-induced lung injury and inflammation. METHODS The expression levels of MINCR and miR-146b-5p in lung tissue status were detected by using quantitative real-time polymerase chain reaction (qRT-PCR), hematoxylin and eosin staining, immunohistochemical staining, and terminal deoxynucleotidyl transferase dUTP nick end labeling assay. Enzyme-linked immunosorbent assay and Western blotting analysis were used to detect the expression of inflammatory factors such as tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-10 in lung tissue. The relationship between MINCR, miR-146b-5p, and TRAF6 was explored using bioinformatics analysis and luciferase assay. RESULTS The expression levels of MINCR were increased in a mouse model of LPS-induced ALI and small airway epithelial cells (SAECs). shMINCR resulted in increased cell viability and decreased apoptosis, which protected against LPS-induced cell damage. shMINCR can inhibit the formation of neutrophil extracellular traps, neutrophil numbers, myeloperoxidase activity, and the production of inflammatory cytokines IL-6, IL-1β, and TNF-α induced by LPS. The silencing of miR-146b-5p reversed the effects of MINCR on LPS-induced lung damage. Sh-MINCR decreased the expression levels of TRAF6 and p-P65 in LPS-induced SAECs and lung tissues. Co-transfection of sh-MINCR with miR-146b-5p inhibitor reversed the effect of sh-MINCR on the expression of TRAF6 and p-P65. CONCLUSIONS MINCR may induce alveolar epithelial cell injury and inflammation and aggravate the progression of ALI/ARDS through miR-146b-5p and TRAF6/NF-κB pathways, which would provide a promising target for the treatment of ALI/ARDS.

Abstract
BACKGROUND Increasing evidence has found that the dysregulation of long non-coding RNAs (lncRNAs) may be important indicators in tumorigenesis. MYC-induced long non-coding RNA (MINCR) has been found to be related with some cancers, such as non-small cell lung cancer and gallbladder cancer. Besides, MINCR has potentially prognostic value for colon cancer (CC) patients' prognosis, yet its function and molecular mechanism in CC are not explored. METHODS qRT-PCR evaluated gene expression, and western blot detected protein level. In vitro and in vivo experiments were adopted to understand the biological role of MINCR in CC. TOP/FOP Flash assay was performed to measure the activity of Wnt/β-catenin pathway. RNA pull down, luciferase reporter and RIP assays were utilized to analyze the relationship among genes. Immunohistochemistry and HE staining techniques were utilized to evaluate Ki67 staining in xenografts. RESULTS MINCR was up-regulated in CC cells. Knockdown of MINCR suppressed cell proliferation and migration. MINCR could up-regulate CTNNB1 via sequestering miR-708-5p, resulting in activated Wnt/β-catenin pathway. The addition of LiCl treatment, miR-708-5p inhibitor or pcDNA3.1/CTNNB1 abolished the inhibitory impacts induced by MINCR silence in CC progression. CONCLUSION MINCR sponges miR-708-5p to up-regulate CTNNB1 and activate Wnt/β-catenin pathway, thus promoting the development CC. Targeting MINCR might shed new light on the therapeutic strategies of CC.

Abstract
Emerging evidence underlined the crucial roles played by long non-coding RNAs (lncRNAs) in glioma. MINCR has been reported in multiple malignancies. Here, we studied its function and potential mechanism in glioma, which remain unclear. Gene expressions were analyzed by qRT-PCR assay. Both in vitro and in vivo assays were conducted to evaluate the cellular function of MINCR in glioma. The subcellular situation of MINCR was detected by subcellular fractionation and FISH assays. Luciferase reporter, RNA pull-down and RNA immunoprecipitation (RIP) assays were combined to investigate potential mechanisms of relevant genes. MINCR was up-regulated in glioma. MINCR depletion markedly refrained glioma cell proliferation, migration and invasion via sponging miR-876-5p. MiR-876-5p suppressed the malignant behaviors of glioma via binding to GSPT1. MINCR shared the binding sites with the 3'-untranslated region of GSPT1 and prevented the binding of miR-876-5p to GSPT1 mRNA, thus up-regulating the level of GSPT1. Moreover, miR-876 inhibition and GSPT1 up-regulation counteracted the functional effect induced by silencing MINCR on glioma progression. Our findings uncovered that MINCR might aggravated glioma cell proliferation and migration via acting as competing endogenous RNA (ceRNA), indicating prospective novel therapeutic target for glioma.

Abstract
BACKGROUND Non-small cell lung cancer (NSCLC) is one of the leading causes of cancer death in the world, and has a relatively low survival rate. Long non-coding RNAs (lncRNAs) have been demonstrated to modulate cancer progression through a variety of molecular mechanisms. We sought to investigate the role and potential mechanism of MYC-induced long non-coding RNA (MINCR) in NSCLC. METHODS Expression levels of MINCR was first identified using The Cancer Genome Atlas (TCGA), further confirmed with specimens from 29 NSCLC patients and three cell lines using qRT-PCR. Overexpression and knockdown of MINCR were performed in NSCLC cell lines through MINCR overexpression vectors and synthesized siRNAs, respectively. The roles of MINCR in NSCLC cell lines, such as cell proliferation, cell cycle arrest, and apoptosis, were identified by MTT, flow cytometry, and Western blot. The modulation of MINCR-regulated genes, including c-Myc and its downstream effectors, as well as apoptosis-associated genes, was analyzed using Western blot. RESULTS MINCR expression was increased in NSCLC patients from TCGA datasets, and was also significantly increased in our collected specimens from NSCLC patients and NSCLC cell lines. Knocking down of MINCR greatly inhibited the growth of NSCLC cell lines PC9 and A549. In addition, silencing of MINCR induced cell cycle arrest and apoptosis. Furthermore, silencing of MINCR reduced the expression levels of oncogene c-Myc and its downstream cyclin A, cyclin D, CD4, and CDK2, as well as apoptosis-associated Bcl-2, while significantly increased the expression levels of cleaved PARP-1. In the meantime, overexpression of MINCR remarkably enhanced cell proliferation of PC9 cells and activated c-Myc and its downstream effectors. CONCLUSION MINCR exerted inhibitory effects on the cell cycle arrest and apoptosis of NSCLC cells by activating c-Myc and its downstream effectors, suggesting that this lncRNA could be used as a potential therapeutic target for the treatment of NSCLC.

Abstract
A growing body of evidence suggests that MYC induced long noncoding RNA (MINCR) is involved in the initiation and progression of various tumors. However, little is known about the biological function and clinical value of MINCR in non-small cell lung cancer (NSCLC). In the present study, results found that MINCR over expression in NSCLC tissue and cell lines was closely related to poor survival in NSCLC. Functional experiments found that decreased MINCR expression inhibits NSCLC cell proliferation and migration and promotes cells apoptosis. Tumor formation assay found that knockdown of MINCR significantly inhibited tumor growth. Results also found that MINCR functions as an oncogene in the metastasis of NSCLC, in part, by acting as a competing endogenous RNA to modulate the miR-126/SLC7A5 axis. Dysfunction of MINCR, miR-126 and SLC7A5 predicted poor prognosis of patients with NSCLC. In conclusion, results suggest that the MINCR-miR-126-SLC7A5 axis plays an important role in the progression of NSCLC and may serve as a potential target for lung cancer diagnosis and treatment.
