Abstract
BACKGROUND Colorectal cancer (CRC) is one of the major gastrointestinal malignancies threatening human health. More and more studies indicate that circular RNAs (circRNAs) are important regulatory factors of CRC, but the mechanism is still indistinct. METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot were used to detect the expression of circ_0084188, microRNA-769-5p (miR-769-5p), and kinesin family member 20A (KIF20A) in CRC tissues. Kaplan-Meier curve was used to analyze the relationship between circ_0084188 expression and the survival rate of CRC patients. Cell proliferation, viability, apoptosis, migration, and invasion were analyzed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), 5-ethynyl-2'-deoxyuridine (EdU), flow cytometry, wound-healing, and transwell assays, respectively. The relationship between miR-769-5p and circ_0084188 or KIF20A was detected by a dual-luciferase reporter and RNA pull-down. The effect of circ_0084188 on tumor growth was verified by xenograft studies in vivo. RESULTS Circ_0084188 and KIF20A were upregulated and miR-769-5p was downregulated in CRC. Circ_0084188 knockdown repressed the proliferation, migration, and invasion of CRC cells, as well as enhanced apoptosis in vitro. Mechanistically, circ_0084188 targeted miR-769-5p, and the reduction of miR-769-5p reversed the effects of circ_0084188 knockdown on cell functional behaviors. KLF20A was a direct miR-769-5p target, and circ_0084188 acted as a sponge for miR-769-5p to regulate the KIF20A level. Moreover, miR-769-5p regulated the functional behaviors of CRC cells by targeting KIF20A. In addition, circ_0084188 knockdown confined the growth of xenograft tumors in vivo. CONCLUSION Circ_0084188 upregulated the expression of KIF20A to promote the tumorigenesis of CRC through miR-769-5p, providing a new therapeutic target for CRC.

Abstract
Colorectal cancer (CRC) and gastric cancer (GC), are the two most common cancers of the gastrointestinal tract, and are serious health concerns worldwide. The discovery of more effective biomarkers for early diagnosis, and improved patient prognosis is important. Non-coding RNAs (ncRNAs), including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), can regulate cellular processes such as apoptosis and the epithelial-mesenchymal transition (EMT) leading to progression and resistance of GC and CRC tumors. Moreover these pathways (apoptosis and EMT) may serve as therapeutic targets, to prevent metastasis, and to overcome drug resistance. A subgroup of ncRNAs is common to both GC and CRC tumors, suggesting that they might be used as biomarkers or therapeutic targets. In this review, we highlight some ncRNAs that can regulate EMT and apoptosis as two opposite mechanisms in cancer progression and metastasis in GC and CRC. A better understanding of the biological role of ncRNAs could open up new avenues for the development of personalized treatment plans for GC and CRC patients.

Abstract
Introduction Colon cancer is a complex disease that involves intricate interactions between cancer cells and theimmune microenvironment. MicroRNAs (miRNAs) have recently emerged as critical regulators of gene expression in cancer, including colon cancer. There is increasing evidence suggesting that miRNA dysregulation plays a crucial role in modulating the immune microenvironment of intestinal cancer. In particular, miRNAs regulate immune cell activation, differentiation, and function, as well as cytokine and chemokine production in intestinal cancer. It is urgent to fully investigate the potential role of intestinal cancer-related miRNAs in shaping the immune microenvironment. Methods Therefore, this paper aims to identify miRNAs that are potentially associated with colon cancer and regulate a large number of genes related to immune function. We explored the role of these genes in colon cancer patient prognosis, immune infiltration, and tumor purity based on data of 174 colon cancer patients though convolutional neural network, survival analysis and multiple analysis tools. Results Our findings suggest that miRNA regulated genes play important roles in CD4 memory resting cells, macrophages.M2, and Mast cell activated cells, and they are concentrated in the cytokinecytokine receptor interaction pathway. Discussion Our study enhances our understanding of the underlying mechanisms of intestinal cancer and provides new insights into the development of effective therapies. Additionally, identification of miRNA biomarkers could aid in diagnosis and prognosis, as well as guide personalized treatment strategies for patients with intestinal cancer.

MicroRNA-769-3p Acts as a Prognostic Factor in Oral Squamous Cell Cancer by Modulating Stromal Genes. Cancers (Basel) 2022; 14:cancers14184373. [PMID: 36139534 PMCID: PMC9496693 DOI: 10.3390/cancers14184373] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Revised: 08/23/2022] [Accepted: 09/05/2022] [Indexed: 12/24/2022] Open
Abstract
miR-769-3p expression is suppressed in the stromal subtype of head and neck squamous cell carcinoma (HNSCC); however, its role in stromal HNSCC has not been fully elucidated. To investigate the biological relevance of miR-769-3p in the stromal phenotype, we established oral squamous cell cancer (OSCC) cell lines, namely CAL27, HSC3, and YD8, overexpressing miR-769-3p. miR-769-3p expression was positively and negatively correlated with interferon-gamma-related genes and MYC target gene sets, respectively. miR-769-3p decreased OSCC cell migration and invasion as well as mesenchymal marker expression and increased epithelial marker expression. Moreover, miR-769-3p enhanced OSCC cell sensitivity to 5-fluorouracil. High miR-769-3p expression was associated with good prognosis of HNSCC patients. Collectively, these results suggest that miR-769-3p suppression enhances stromal gene expression and promotes the epithelial-to-mesenchymal transition. Therefore, miR-769-3p may be a potential biomarker of the miRNA phenotype in OSCC patients.

Abstract
<b><i>Introduction:</i></b> This study aimed to detect the function of retinoic acid receptor responder 1 (RARRES1) and its regulator miR-769-5p in the growth and mobility of osteosarcoma cells. <b><i>Methods:</i></b> The Gene Expression Omnibus database was applied to analyze RARRES1 and miR-769-5p expression, and the survival rate of osteosarcoma patients. The target association between miR-769-5p and RARRES1 was speculated by miRWalk, TargetScan, and miRanda Web sites, as well as affirmed by dual luciferase assay. RARRES1 expression was tested by quantitative real-time polymerase chain reaction and Western blot. The malignant properties of MG-63 and U2OS cells were assessed by a series of biological experiments. <b><i>Results:</i></b> RARRES1 was lowly expressed in osteosarcoma patients, which resulted in unfavorable survival. Depletion of RARRES1 promoted the viability and mobility of osteosarcoma cells. Moreover, miR-769-5p was affirmed as an upstream regulator of RARRES1 and negatively regulated RARRES1 expression. miR-769-5p upregulation accelerated the viability and mobility of osteosarcoma cells, which can be blocked by RARRES1 overexpression. miR-769-5p inhibitor suppressed the effect of malignant viability and mobility of osteosarcoma cells, while this suppressive effect was abolished by depleting RARRES1. <b><i>Discussion/Conclusion:</i></b> miR-769-5p promoted cell viability, invasion, and migration by reducing RARRES1 expression in osteosarcoma cells, which might provide novel targets for the treatment of osteosarcoma.

Abstract
Osteosarcoma (OS) is a primary malignant tumor characterized by a high metastatic potential and poor prognosis. The dysregulation of miR-588 has been demonstrated to serve crucial roles in the progression of numerous types of cancer. The present study aimed to investigate the expression and function of miR-588 in the development of OS. To do so, clinical samples were collected and analyzed, and in vitro experiments were conducted. A total of 104 patients with OS were recruited between 2012 and 2014. The expression of miR-588 was analyzed by reverse transcription quantitative PCR. The association between miR-588 expression and the clinicopathological characteristics and survival rate of patients with OS was evaluated. Furthermore, Cell Counting Kit-8 and Transwell assays were used to evaluate the effect of miR-588 on the proliferation and the migratory and invasive abilities of various OS cell lines. The results demonstrated that miR-588 expression in OS tissues and cells was significantly lower compared with normal tissues and cells. In addition, miR-588 expression was closely associated with the Musculoskeletal Tumor Society (MSTS) staging of patients with OS. miR-588 expression and MSTS staging were therefore considered as independent indicators for the prognosis of patients with OS. In addition, miR-588 downregulation significantly stimulated the proliferation and migratory and invasive abilities of OS cells. Taken together, these findings indicated that miR-588 may serve as an independent prognostic factor and tumor suppressor in OS.

Abstract
Colorectal cancer (CRC) is the third leading cause of cancer death in the world, and its incidence is rising in developing countries. Treatment with 5-Fluorouracil (5-FU) is known to improve survival in CRC patients. Most anti-cancer therapies trigger apoptosis induction to eliminate malignant cells. However, de-regulated apoptotic signaling allows cancer cells to escape this signaling, leading to therapeutic resistance. Treatment resistance is a major challenge in the development of effective therapies. The microRNAs (miRNAs) play important roles in CRC treatment resistance and CRC progression and apoptosis. This review discusses the role of miRNAs in contributing to the promotion or inhibition of apoptosis in CRC and the role of miRNAs in modulating treatment resistance in CRC cells.

Abstract
Long intergenic non–protein-coding RNA 324 (LINC00324) is abnormally expressed in multiple human cancer types and plays an important role in cancer initiation and progression. This study showed that LINC00324 was expressed at higher levels in retinoblastoma (RB) tumors and cell lines than in control samples. Increased LINC00324 expression closely correlated with the TNM stage, optic nerve invasion, and shorter overall survival among patients with RB. The knockdown of LINC00324 decreased RB cell proliferation, colony formation, migration, and invasion, and promoted apoptosis and cell cycle arrest in vitro as well as hindered tumor growth in vivo. With respect to the mechanism, LINC00324 acted as a competing endogenous RNA for microRNA-769-5p (miR-769-5p) in RB cells. The mRNA of signal transducer and activator of transcription 3 (STAT3) was identified as a direct target of miR-769-5p in RB cells. Rescue experiments indicated that restoration of STAT3 expression attenuated the tumor-suppressive actions of miR-769-5p in RB cells. Downregulation of miR-769-5p or restoration of STAT3 almost completely reversed the effects of LINC00324 knockdown on RB cells. Our findings describe a novel RB-related LINC00324–miR-769-5p–STAT3 axis that is implicated in the malignancy of RB in vitro and in vivo. This study may point to innovative therapeutic targets in RB.

Abstract
BACKGROUND Triple-negative breast cancer (TNBC) is one of the leading causes of death among females around the world. However, the molecular mechanism of the disease among TNBC patients remains to be further studied. METHODS In our study, four microarray data and two high throughput sequencing data were acquired from the GEO database, and the differentially expressed genes (DEGs) between TNBC and normal tissues had been analyzed. Analysis of functional enrichment and pathway enrichment of DEGs was conducted by the Funrich software, and protein-protein interaction (PPI) network gained from the STRING, and hub genes were confirmed by the Cytoscape. Kaplan-Meier plotter (KM plotter) online dataset had been used to analyze DEGs of overall survival (OS), and progression-free survival (PFS). RESULTS In total, 1638 DEGs were gained in our study covering 984 upregulated and 654 downregulated genes. Moreover, a PPI network was constructed, and cyclin-dependent kinase 1 (CDK1), cyclin B1 (CCNB1), and cyclin A2 (CCNA2) were found as top genes with higher node degrees. CDK1, CCNA2, and CCNB1were obviously enriched in the cell cycle. The top upregulated genes including CDK1, CCNB1, CCNA2, and PLK1 were overexpressed in TNBC, and correlated with worse OS in breast cancer. High expression of CCNB1 was correlated with worse PFS in TNBC (HR = 1.42, 95% CI: 1.04-1.94, P = 0.028). Besides, there was a correlation between CCNB1 and CDK1 in TNBC, as well as between CCNA2 and CDK1 (r = 0.804, P < 0.001; r = 0.577, P < 0.001, respectively). CONCLUSION Our results suggest that cyclin CDK1, CCNB1, and CCNA2 are overexpressed in TNBC and they could act as novel biomarkers for the diagnosis and treatment of TNBC.

Abstract
Chronic venous disease (CVD) is a vascular disease of lower limbs with high prevalence worldwide. Pathologic features include varicose veins, venous valves dysfunction and skin ulceration resulting from dysfunction of cell proliferation, apoptosis and angiogenesis. These processes are partly regulated by microRNA (miRNA)-dependent modulation of gene expression, pointing to miRNA as a potentially important target in diagnosis and therapy of CVD progression. The aim of the study was to analyze alterations of miRNA and gene expression in CVD, as well as to identify miRNA-mediated changes in gene expression and their potential link to CVD development. Using next generation sequencing, miRNA and gene expression profiles in peripheral blood mononuclear cells of subjects with CVD in relation to healthy controls were studied. Thirty-one miRNAs and 62 genes were recognized as potential biomarkers of CVD using DESeq2, Uninformative Variable Elimination by Partial Least Squares (UVE-PLS) and ROC (Receiver Operating Characteristics) methods. Regulatory interactions between potential biomarker miRNAs and genes were projected. Functional analysis of microRNA-regulated genes revealed terms closely related to cardiovascular diseases and risk factors. The study shed new light on miRNA-dependent regulatory mechanisms involved in the pathology of CVD. MicroRNAs and genes proposed as CVD biomarkers may be used to develop new diagnostic and therapeutic methods.

Abstract
Recently, a number of microRNAs (miRNAs) have been reported to play different roles in human cancers, including colorectal cancer (CRC). However, the specific role of miR-758 has not been clarified in CRC. Therefore, the aim of the present study was to explore the role of miR-758 in CRC. RT-qPCR and western blot analysis were used to quantify the expression of miR-758 and genes. The function of miR-758 in CRC was investigated using Transwell, CCK-8 and luciferase reporter assays. According to the results, the downregulation of miR-758 expression was associated with aggressive behavior and poor prognosis in CRC patients. miR-758 was shown to restrain the cell viability and metastasis in CRC. In addition, it was confirmed that miR-758 directly targets PAX6 and inhibits CRC progression through targeting PAX6. The results also revealed that miR-758 blocked EMT and PI3K/AKT pathway in CRC. In conclusion, miR-758 acts as a tumor suppressor in CRC by downregulating PAX6.

Abstract
Colorectal cancer (CRC) is the third most common malignancy and the second leading cause of cancer-associated mortality worldwide. CRC currently has no specific biomarkers to promote its diagnosis and treatment and the underlying mechanisms regulating its pathogenesis have not yet been determined. MicroRNAs (miRs) are small, non-coding RNAs that exhibit regulatory functions and have been demonstrated to serve a crucial role in the post-transcriptional regulatory processes of gene expression that is associated with cell physiology and disease progression. Recently, abnormal miR-20a expression has been identified in a number of cancers types and this has become a novel focus within cancer research. High levels of miR-20a expression have been identified in CRC tissues, serum and plasma. In a recent study, miR-20a was indicated to be present in feces and to exhibit a high sensitivity to CRC. Therefore, miR-20a may be used as a marker for CRC and an indicator that can prevent the invasive examination of patients with this disease. Changes in the expression of miR-20a during chemotherapy can be used as a biomarker for monitoring resistance to treatment. In conclusion, miR-20a exhibits the potential for clinical application as a novel diagnostic biomarker and therapeutic target for use in patients with CRC. The present study focused on the role and mechanisms of miR-20a in CRC.

Onco Targets Ther 2019; 12:9177-9187. [PMID: 31807002 PMCID: PMC6842300 DOI: 10.2147/ott.s222836] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Accepted: 10/18/2019] [Indexed: 12/24/2022] Open
Abstract
Background Accumulating evidence supports the involvement of microRNAs (miRNAs) in the progression of human cancers including glioma. Recently, miR-769-5p has been reported to play a tumor suppressive role in colorectal cancer and lung cancer, whereas it exerts an oncogenic role in melanoma. However, the role of miR-769-5p and its related mechanism are poorly elucidated. Methods The levels of miR-769-5p in glioma tissues and adjacent non-tumor tissues were detected by qRT-PCR. In addition, the effects of miR-769-5p on cell proliferation and apoptosis were evaluated by CCK-8, EdU, colony formation and flow cytometric assays, respectively. Meanwhile, the dual-luciferase reporter assay was used to investigate the interaction of miR-769-5p and lysine methyltransferase 2A (KMT2A) in glioma. Results We found that miR-769-5p expression was strongly upregulated in glioma tissues and cell lines. Glioma tissues with high World Health Organization (WHO) grades had obvious higher levels of miR-769-5p compared to samples with low WHO grades. Interestingly, glioma patients highly expressing miR-769-5p showed prominent poorer survivals. Knockdown of miR-769-5p significantly suppressed cell proliferation and resulted in apoptosis in glioma cells. Additionally, miR-769-5p silencing restrained in vivo growth of glioma cells in mice. Interestingly, KMT2A was identified to be a direct target of miR-769-5p in glioma cells. The expression of KMT2A mRNA was downregulated in glioma tissues and inversely correlated with miR-769-5p level. KMT2A overexpression inhibited cell proliferation and induced the apoptosis of A172 cells. Moreover, siRNA-mediated KMT2A silencing could partially abolish miR-769-5p knockdown-induced suppressive effects on A172 cells. Conclusion In summary, our findings suggest that targeting miR-769-5p/KMT2A axis may be a promising therapeutic target for glioma treatment.

Abstract
Hepatocellular carcinoma (HCC) is the commonest primary liver cancer with highly aggressive features. MicroRNAs (miRNAs) are demonstrated to play important roles in the tumorigenesis and progression of HCC. miR-769-5p is a recently identified cancer-associated miRNA. But, the expression level of miR-769-5p and its function in HCC are unexplored. In this study, we found that miR-769-5p expression was obviously increased in HCC samples compared to adjacent noncancerous liver tissues. Additionally, we revealed that miR-769-5p was over-expressed in HCC cells as compared with LO2 cells. Notably, HCC tissues from patients with tumor size ≥5 cm, venous infiltration and advanced tumor stages showed higher levels of miR-769-5p compared to those from corresponding controls. Interestingly, our data indicated that HCC patients highly expressing miR-769-5p had significant shorter survivals. Next, functional experiments verified that miR-769-5p knockdown markedly suppressed HCC cell proliferation, migration and invasion. Conversely, ectopic expression of miR-769-5p promoted these biological behaviors of Hep3B cells. Furthermore, depletion of miR-769-5p repressed the growth and metastasis of HCCLM3 cells in vivo. Importantly, miR-769-5p inversely modulated RING1 and YY1 binding protein (RYBP) by directly binding to 3' untranslated region (UTR) in HCC cells. The expression of RYBP mRNA was down-regulated in HCC tissues and negatively correlated with miR-769-5p level. RYBP overexpression remarkably inhibited the proliferation, migration and invasion of HCCLM3 cells. Accordingly, knockdown of RYBP partially abolished miR-769-5p silencing-induced tumor suppressive effects on HCCLM3 cells. In summary, our study revealed the up-regulated expression of miR-769-5p, which contributed to HCC progression possibly by targeting RYBP.

Abstract
AIMS Lycorine is a kind of natural alkaloid with anti-cancer potential. It has been demonstrated that lycorine processes high activity and specificity against the progression of cancers. However, the underlying molecular mechanisms by which lycorine regulates the formation and development of non-small cell lung cancer (NSCLC) remain largely unknown. MAIN METHODS The effects of lycorine on the growth of NSCLC cells were determined by the cell counting kit-8 (CCK-8) assay, colony formation and flow cytometry analysis. RT-qPCR was performed to detect the expression of microRNA with lycorine treatment. The binding of miRNA and target genes was confirmed by luciferase reporter assay. KEY FINDINGS Lycorine significantly inhibited the proliferation and induced apoptosis of NSCLC cells. Mechanistically, lycorine up-regulated the expression of microRNA-186 in NSCLC cells. Depletion of miR-186 significantly reversed the suppressive effect of lycorine on the proliferation of NSCLC cells. Furthermore, the cyclin dependent kinase 1 (CDK1) was identified as one of the binding candidates of miR-186. Experimental analysis showed that miR-186 bound the 3'-untranslated region (3'-UTR) of CDK1 and suppressed the level of CDK1 in NSCLC cells. Consistently, exposure of lycorine significantly decreased the expression of CDK1. Restoration of CDK1 remarkably attenuated the inhibition of lycorine on the proliferation of NSCLC cells. SIGNIFICANCE Our results uncovered the novel molecular mechanism of lycorine in suppressing the progression of NSCLC partially via regulating the miR-186/CDK1 axis.

Abstract
Non-small cell lung cancer (NSCLC) is demonstrated as one of the most common malignant tumors and accounts for about 25% of cancer-related deaths each year. Extensive bodies of studies have manifested that microRNAs (miRNAs) play pivotal roles in the development of numerous malignant tumors by involving in modulation of cell biological processes. Although miR-4319 has been validated to execute tumor suppressor properties in triple-negative breast cancer, explorations on the function and latent mechanism of miR-4319 participating in NSCLC are still unclear. In this study, we proved that miR-4319 acted as a tumor suppressor in NSCLC progression via restraining cell proliferation and migration as well as boosting apoptosis. Further, miR-4319 bound with LIN28 and negatively regulated the expression of LIN28. Our data unveiled that LIN28 promoted RFX5 mRNA stability and miR-4319 led to the destabilization of RFX5 by targeting LIN28. In addition, RFX5 motivated the transcription of YAP and enhanced expression of YAP abolished the miR-4319 upregulation-mediated suppressive regulation of NSCLC tumorigenesis. In conclusion, miR-4319 dampened YAP expression to mitigate the tumorigenesis of NSCLC through inhibiting LIN28-mediated RFX5 stability, which offered an insight into the molecular mechanism underlying miR-4319 in NSCLC development.

Abstract
MicroRNAs (miRNAs) are often abnormally expressed in human cancers to act as either oncogenes or tumor suppressor genes. MiRNA-501 (miR-501) has been found to be abnormally expressed in certain types of cancer, but its expression and biological role in hemangioma remain to be fully elucidated. In this study, the expression of miR-501 in hemangioma cell lines was analyzed by quantitative real-time polymerase chain reaction (qRT-PCR). The TargetScan algorithm, luciferase activity reporter assay, and Western blot analysis were conducted to validate homeobox D10 (HOXD10) as a direct target of miR-501. The results revealed that miR-501 expression was upregulated in hemangioma cell lines. Downregulation of miR-501 inhibited hemangioma cell proliferation, cell cycle progression, colony formation, migration, and invasion in vitro. Bioinformatics analysis indicated that HOXD10 was a putative target of miR-501. In addition, in a luciferase reporter system, it was confirmed that HOXD10 is a direct target of miR-501. It was also demonstrated HOXD10 downregulation reversed the effects of the miR-501 inhibitor on hemangioma cell activities. These findings indicated that miR-501 targeted HOXD10 to promote hemangioma cell processes, suggesting that miR-501 has an oncogenic role in the pathogenesis of hemangioma.
