Deciphering the functional landscape and therapeutic implications of noncoding RNAs in the TGF-β signaling pathway in colorectal cancer: A comprehensive review. Pathol Res Pract 2024; 255:155158. [PMID: 38320438 DOI: 10.1016/j.prp.2024.155158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 01/18/2024] [Accepted: 01/18/2024] [Indexed: 02/08/2024]
Abstract
Colorectal cancer (CRC) remains a major global health concern, necessitating an in-depth exploration of the intricate molecular mechanisms underlying its progression and potential therapeutic interventions. Transforming Growth Factor-β (TGF-β) signaling, a pivotal pathway implicated in CRC plays a dual role as a tumor suppressor in the early stages and a promoter of tumor progression in later stages. Recent research has shed light on the critical involvement of noncoding RNAs (ncRNAs) in modulating the TGF-β signaling pathway, introducing a new layer of complexity to our understanding of CRC pathogenesis. This comprehensive review synthesizes the current state of knowledge regarding the function and therapeutic potential of various classes of ncRNAs, including microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), in the context of TGF-β signaling in CRC. The intricate interplay between these ncRNAs and key components of the TGF-β pathway is dissected, revealing regulatory networks that contribute to the dynamic balance between tumor suppression and promotion. Emphasis is placed on how dysregulation of specific ncRNAs can disrupt this delicate equilibrium, fostering CRC initiation, progression, and metastasis. Moreover, the review provides a critical appraisal of the emerging therapeutic strategies targeting ncRNAs associated with TGF-β signaling in CRC. The potential of these ncRNAs as diagnostic and prognostic biomarkers is discussed, highlighting their clinical relevance. Additionally, the challenges and prospects of developing RNA-based therapeutics, such as RNA interference and CRISPR/Cas-based approaches, are explored in the context of modulating TGF-β signaling for CRC treatment. In conclusion, this review offers a comprehensive overview of the intricate interplay between ncRNAs and the TGF-β signaling pathway in CRC. By unraveling the functional significance of these regulatory elements, we gain valuable insights into the molecular landscape of CRC, paving the way for the development of novel and targeted therapeutic interventions aimed at modulating the TGF-β signaling cascade through the manipulation of ncRNAs.

[PMID: 36736694 DOI: 10.1016/j.jare.2023.01.011] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Revised: 01/06/2023] [Accepted: 01/12/2023] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Tripartite motif (TRIM) family proteins have more than 80 members and are widely found in various eukaryotic cells. Most TRIM family proteins participate in the ubiquitin-proteasome degradation system as E3-ubiquitin ligases; therefore, they play pivotal regulatory roles in the occurrence and development of tumors, including tumor immune escape. Due to the diversity of functional domains of TRIM family proteins, they can extensively participate in multiple signaling pathways of tumor immune escape through different substrates. In current research and clinical contexts, immune escape has become an urgent problem. The extensive participation of TRIM family proteins in curing tumors or preventing postoperative recurrence and metastasis makes them promising targets. AIM OF REVIEW The aim of the review is to make up for the gap in the current research on TRIM family proteins and tumor immune escape and propose future development directions according to the current progress and problems. KEY SCIENTIFIC CONCEPTS OF REVIEW This up-to-date review summarizes the characteristics and biological functions of TRIM family proteins, discusses the mechanisms of TRIM family proteins involved in tumor immune escape, and highlights the specific mechanism from the level of structure-function-molecule-pathway-phenotype, including mechanisms at the level of protein domains and functions, at the level of molecules and signaling pathways, and at the level of cells and microenvironments. We also discuss the application potential of TRIM family proteins in tumor immunotherapy, such as possible treatment strategies for combination targeting TRIM family protein drugs and checkpoint inhibitors for improving cancer treatment.

[PMID: 37186007 DOI: 10.1111/cas.15820] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Revised: 04/03/2023] [Accepted: 04/06/2023] [Indexed: 05/17/2023] Open
Abstract
Circular RNAs (circRNAs) play crucial roles in various biological processes, including prostate cancer (PCa). However, the precise roles and mechanism of circRNAs are complicated. Hence, we studied the function of a circRNA that might be involved in the progression of PCa. In this study, we found that circARHGEF28 was frequently downregulated in PCa tissues and cell lines. Furthermore, gain- and loss-of function experiments in vitro showed that circARHGEF28 inhibited proliferation, migration, and invasion of PCa. Additionally, circARHGEF28 suppressed PCa progression in vivo. Bioinformatics analysis and RNA pull-down and capture assay found that circARHGEF28 sponged miR-671-5p in PCa cells. Importantly, qRT-PCR and dual luciferase assays found that Lectin galactoside-binding soluble 3 binding protein (LGALS3BP) was downstream of miR-671-5p, and western blot analysis further confirmed that LGALS3BP negatively regulated the nuclear factor kappa-B (NF-κB) pathway. These results demonstrated that circARHGEF28 abolished the degradation of LGALS3BP by sponging miR-671-5p, thus blocking the activation of the NF-κB pathway. Our findings revealed that circARHGEF28/miR-671-5p/LGALS3BP/NF-κB may be an important axis that regulates PCa progression.

Abstract
Dysregulated miRNAs have been demonstrated to be associated with the progression of colon cancer. The dysregulation of miR-3133 was observed in colon cancer, but its specific function was unclear. The functional role of miR-3133 in colon cancer was investigated in this study. A total of 113 colon cancer patients were included. miR-3133 expression was evaluated by PCR. The biological effects of miR-3133 in colon cancer cells were assessed with the help of the transwell and CCK8 assay. The prognostic value of miR-3133 was estimated by a series of statistical analyses. In mechanism, the interaction between miR-3133 and RUFY3 was evaluated by luciferase reporter. The significant downregulation of miR-3133 was observed in colon cancer, which showed a significant association with the advanced TNM stage and bad survival of patients. miR-3133 and TNM stage were identified as independent prognostic indicators of colon cancer. In vitro, the overexpression of miR-3133 exerted a dramatically inhibitory effect on cellular processes of colon cancer, which were enhanced by miR-3133 knockdown. Additionally, miR-3133 could negatively regulate the luciferase activity and expression of RUFY3, which was speculated as the underlying mechanism mediating the regulatory effect of miR-3133. miR-3133 functioned as a prognostic biomarker indicating the progression and prognosis of colon cancer, and it also served as a tumor suppressor via negatively regulating RUFY3, which provides a potential therapeutic target for colon cancer.

Abstract
We propose a novel blood biomarker detection method that uses miRNA super-resolution imaging to enable the early diagnosis of Alzheimer's disease (AD). Here, we report a singlemolecule detection method for visualizing disease-specific miRNA in tissue from an AD mice model, and peripheral blood mononuclear cells (PBMCs) from AD patients. Using optimized Magnified Analysis of Proteome (MAPs), we confirmed that five miRNAs contribute to neurodegenerative disease in the brain hippocampi of 5XFAD and wild-type mice. We also assessed PBMCs isolated from the whole blood of AD patients and a healthy control group, and subsequently analyzed those samples using miRNA super-resolution imaging. We detected more miR-200a-3p expression in the cornu ammonis 1 and dentate gyrus regions of 3 month-old 5XFAD mice than in wild-type mice. Additionally, miRNA super-resolution imaging of blood provides AD diagnosis platform for studying miRNA regulation inside cells at the single molecule level. Our results present a potential liquid biopsy method that could improve the diagnosis of early stage AD and other diseases. [BMB Reports 2023; 56(3): 190-195].

CircRNA-PTPRA Knockdown Inhibits Atherosclerosis Progression by Repressing ox-LDL-Induced Endothelial Cell Injury via Sponging of miR-671-5p. Biochem Genet 2023; 61:187-201.

Abstract
Atherosclerosis (AS) is a chronic inflammatory disease with high morbidity and mortality rates worldwide. This study aimed to investigate the role of circular RNA protein tyrosine phosphatase receptor type A (circRNA_PTPRA) in oxidized low-density lipoprotein (ox-LDL)-induced human umbilical vein endothelial cell (HUVECs) injury and its underlying molecular mechanism. The expression of circRNA-PTPRA and microRNA (miR)-671-5p was assessed by quantitative reverse transcription PCR (qRT-PCR). The interaction between circRNA-PTPRA and miR-671-5p was predicted using bioinformatic analysis. Cell viability and apoptosis were determined using the Cell Counting Kit-8 (CCK-8) assay and flow cytometry, respectively. Inflammation in HUVECs was analyzed by measuring the secretion of tumor necrosis factor alpha (TNF-α), interleukin-1beta (IL-1β), and IL-6 using enzyme-linked immunosorbent assay (ELISA). Cleaved-caspase-3 expression was assessed using western blotting. The results indicated that circRNA-PTPRA expression was significantly increased and miR-671-5p expression was decreased in the serum of patients with AS and in ox-LDL-treated HUVECs. The interaction between circRNA-PTPRA and miR-671-5p was verified by dual luciferase reporter and RNA pull-down assays. In HUVECs, downregulation of circRNA-PTPRA reversed ox-LDL-induced reduction in cell viability, increase in apoptosis, and enhanced inflammation, whereas all these effects mediated by circRNA-PTPRA downregulation in ox-LDL-treated HUVECs were abolished by miR-671-5p downregulation. In conclusion, circRNA-PTPRA downregulation protects against ox-LDL-induced HUVECs injury by upregulating miR-671-5p, thereby providing potential therapeutic targets for AS.

Downregulation of miR-671-5p promotes IL-10 mRNA increase in porcine moDCs stimulated with the probiotic BB12. Mol Biol Rep 2023; 50:919-925.

Abstract
BACKGROUND Previous work showed that the microRNA (miRNA) miR-671-5p was upregulated in monocyte-derived dendritic cells (moDCs) stimulated with Bifidobacterium animalis subsp. lactis BB12 (BB12) with no increase in IL-10 after six hours of stimulation. In this work, we performed an in silico prediction of genes targeted by miR-671-5p and which are the terms and pathways involved with it. Also, miR-671-5p was transiently downregulated to assess its effect on IL-10 regulation. METHODS AND RESULTS First, we performed a Gene Ontology enrichment analysis to predict immune response terms and pathways involved with miR-671-5p. Some of the terms and pathways found were related to the immune response promoted by the probiotic, as the terms "negative regulation of the inflammatory response to an antigenic stimulus" and "cancer" were highlighted. Then, to assess the role of miR-671-5p in IL-10 regulation, moDCs were derived from porcine peripheral blood and later transfected with miR-671-5p antisense oligonucleotide (ASO). Flow cytometry was employed to evaluate the transfection efficiency. Then, the moDCs were stimulated with BB12, and the expression of IL-10 was assessed by RT-qPCR and ELISA. An increase in IL-10 transcript in miR-671-5p-ASO-transfected moDCs stimulated with BB12 was observed compared with moDCs stimulated with BB12 but not transfected. These results suggest the participation of miR-671-5p as a negative regulator of IL-10. CONCLUSION These findings suggest that miR-671-5p participates in the downregulation of IL-10, as previously predicted in silico by our work group. miR-671-5p could play an essential role in the immunomodulation promoted by the probiotic BB12.

Abstract
miR-671 is encoded by a gene on 7q36.1 and contributes to the pathogenesis of a variety of disorders, including diverse types of cancers, atherosclerosis, ischemic stroke, liver fibrosis, osteoarthritis, Parkinson's disease, rheumatoid arthritis, acute myocardial infarction and Crohn's disease. In the context of cancer, different studies have revealed opposite roles for this miRNA. In brief, it has been shown to be down-regulated in pancreatic ductal carcinoma, ovarian cancer, gastric cancer, osteosarcoma, esophageal squamous cell carcinoma and myelodysplastic syndromes. Yet, miR-671 has been up-regulated in glioma, colorectal cancer, prostate cancer and hepatocellular carcinoma. Studies in breast, lung and renal cell carcinoma have reported inconsistent results. The current review aims at summarization of the role of miR-671 in these disorders focusing on its target mRNA in each context and dysregulated signaling pathways. We also provide a summary of the role of this miRNA as a prognostic factor in malignancies.

Abstract
Colorectal cancer (CRC) is the third most common type of cancer worldwide amongst males and females. CRC treatment is multidisciplinary, often including surgery, chemotherapy, and radiotherapy. Early diagnosis of CRC can lead to treatment initiation at an earlier stage. Blood biomarkers are currently used to detect CRC, but because of their low sensitivity and specificity, they are considered inadequate diagnostic tools and are used mainly for following up patients for recurrence. It is necessary to detect novel, noninvasive, specific, and sensitive biomarkers for the screening and diagnosis of CRC at earlier stages. The tumor microenvironment (TME) has an essential role in tumorigenesis; for example, extracellular vesicles (EVs) such as exosomes can play a crucial role in communication between cancer cells and different components of TME, thereby inducing tumor progression. The importance of miRNAs that are sorted into exosomes has recently attracted scientists’ attention. Some unique sequences of miRNAs are favorably packaged into exosomes, and it has been illustrated that particular miRNAs can be directed into exosomes by special mechanisms that occur inside the cells. This review illustrates and discusses the sorted and transported exosomal miRNAs in the CRC microenvironment and their impact on CRC progression as well as their potential use as biomarkers.

Abstract
As explorations deepen, the role of microRNAs (miRNAs) in lung squamous cell carcinoma (LUSC), from its emergence to metastasis and prognosis, has elicited extensive concern. LUSC-related miRNA and mRNA samples were acquired from The Cancer Genome Atlas (TCGA) database. The data were initially screened and pretreated, and the R platform and series analytical tools were used to identify the specific and sensitive biomarkers. Seven miRNAs and 15 hub genes were found to be closely related to the overall survival of patients with LUSC. Determination of the expression of these miRNAs can help improve the overall survival of LUSC patients. The 15 hub genes correlated with overall survival (OS). The new miRNA markers were identified to predict the prognosis of LUSC. The findings of this study offer novel views on the evolution of precise cancer treatment approaches with high reliability.

Abstract
Accumulating evidence supports that exosomal RNAs are crucial in tumor microenvironment and may be used as diagnostic biomarkers for cancers. This study aimed to determine the role of exosomal circular RNA_protein tyrosine phosphatase receptor type A (circ_PTPRA) in colorectal cancer (CRC). The morphology of exosomes was identified by transmission electron microscopy (TEM), and several exosome-specific proteins were quantified by western blot. The expression of circ_PTPRA, miR-671-5p and SMAD family member 4 (SMAD4) was detected using quantitative polymerase chain reaction (qPCR). Cell cycle was assessed using flow cytometry assay. Cell proliferation was assessed by MTT assay. Radiosensitivity was observed according to colony growth and cell apoptosis rate by colony formation assay and flow cytometry assay. The protein levels of proliferation- and apoptosis-related markers and SMAD4 were measured by western blot. The predicted relationship between miR-671-5p and circ_PTPRA or SMAD4 was verified by dual-luciferase reporter assay. Animal study was performed to investigate the role of exosomal circ_PTPRA in vivo. Circ_PTPRA expression was declined in serumal exosomes from CRC patients and CRC cell lines. Exosomal circ_PTPRA induced CRC cell cycle arrest and inhibited cell proliferation. Besides, exosomal circ_PTPRA promoted radiosensitivity of CRC cells, leading to inhibitory colony formation and increased apoptotic rate. In mechanism, circ_PTPRA functioned as a competing endogenous RNA (ceRNA) to increasing SMAD4 level by binding to miR-671-5p. Rescue experiments concluded that circ_PTPRA inhibited CRC growth and radioresistance by decreasing miR-671-5p expression, and miR-671-5p inhibition also inhibited CRC growth and radioresistance by enriching SMAD4 expression. Moreover, exosomal circ_PTPRA blocked tumor growth in vivo. Exosomal circ_PTPRA enhanced CRC cell radiosensitivity and inhibited CRC malignant development partially by regulating the miR-671-5p/SMAD4 pathway, hinting that exosomal circ_PTPRA might be used as a potential predicted and therapeutic target for CRC.

Abstract
MicroRNA (miR)‑671‑5p serves as a tumor suppressor in several types of cancer, including gastric and breast cancer. However, the function of miR‑671‑5p in non‑small cell lung cancer (NSCLC) has not been described in detail. The present study aimed to investigate the role of miR‑671‑5p in NSCLC. The expression levels of miR‑671‑5p were determined in NSCLC tissue samples and cell lines using reverse transcription‑quantitative PCR. Prediction of miR‑671‑5p targets was performed using the TargetScan database and verified by luciferase reporter assay and western blot analysis. Functional experiments, including Cell Counting Kit‑8, wound healing and Transwell assays, were performed in NSCLC cells. The results of the present study demonstrated that lower expression levels of miR‑671‑5p were observed in NSCLC tissues and cell lines compared with those in the corresponding controls. Low miR‑671‑5p levels were significantly associated with an advanced Tumor‑Node‑Metastasis stage and lymph node metastasis in patients with NSCLC. Microfibril‑associated protein 3‑like (MFAP3L) was confirmed to be a direct target of miR‑671‑5p. The proliferative, migratory and invasive abilities of NSCLC cells were suppressed following transfection with miR‑671‑5p mimics and promoted by the miR‑671‑5p inhibitor compared with those in the respective control groups. In addition, the effects of miR‑671‑5p on cell proliferation, migration and invasion, as well as the expression levels of proliferating cell nuclear antigen, E‑cadherin, N‑cadherin and vimentin were reversed by MFAP3L overexpression. In conclusion, targeting the miR‑671‑5p/MFAP3L signaling pathway may be a promising therapeutic strategy for NSCLC treatment.

Abstract
MicroRNAs (miRNAs) could be potential biomarkers for glioblastoma multiforme (GBM) prognosis and response to therapeutic agents. We previously demonstrated that the cancer stem cell marker Musashi-1 (MSI1) is an RNA binding protein that promotes radioresistance by increasing downstream RNA stability. To identify that MSI1 interacts with miRNAs and attenuates their function, we also get candidate miRNAs from the mRNA seq by predicting with TargetScan software. miR-671-5p in GBM cells interacts with MSI1 by intersecting the precipitated miRNAs with the predicted miRNAs. Notably, overexpression of MSI1 reversed the inhibitory effect of miR-671-5p. The phenotype of miR-671-5p in GBM cells could affect radiosensitivity by modulating the posttranscriptional activity of STAT3. In addition, miR-671-5p could attenuate tumor migration and cancer stem cell (CSC) characteristics by repressing the posttranscriptional activity of TRAF2. MSI1 may regulate GBM radioresistance, CSCs and tumor motility through miR-671-5p inhibition to increasing STAT3 and TRAF2 presentation. In vivo, the GBM tumor size was inversely correlated with miR-671-5p expression, but tumorigenesis was promoted by STAT3 and TRAF2 activation in the miR-671-5p-positive GBM population. miR-671-5p could be activated as a novel therapeutic target for GBM and has potential application as a predictive biomarker of glioblastoma prognosis.

Abstract
OBJECTIVES Colon cancer (CC) is the third largest cancer worldwide. Investigation of the molecular mechanism of CC progression helps to explore novel therapeutic targets. We attempted to understand the modulatory mechanism of miR-142-3p in CC cell autophagy and CC progression, which will lay a theoretical groundwork for seeking potential diagnostic and therapeutic targets for CC. METHODS Through bioinformatics methods, miRNA expression data were subjected to differential analysis for identification of target miRNA. Downstream target mRNAs were predicted and gene set enrichment analysis (GSEA) was completed. qRT-PCR assessed gene expression in cells. Cell Counting Kit-8, cell doubling time calculation, colony formation, and flow cytometry were used to assess cellular biological functions. Dual-luciferase assay was used for targeting relationship validation of the target miRNA and mRNA. Western blot was performed to evaluate expression of proteins related to HEDGEHOG signaling pathway and autophagy. RESULTS miR-142-3p was markedly highly expressed in CC, and high miR-142-3p expression in CC patients was implicated with relatively poor prognosis. Over-expressing miR-142-3p facilitated proliferation and inhibited apoptosis of CC cells, whereas silencing it produced an opposite result. miR-142-3p targeted and decreased TP53INP2 level. TP53INP2 over-expression suppressed the HEDGEHOG signaling pathway and induced the activation of CC cell autophagy. Rescue experiments revealed that influence of miR-142-3p inhibitor on CC cell proliferation and apoptosis could be reversed by silencing TP53INP2. CONCLUSION miR-142-3p hampered tumor cell autophagy and promoted CC progression via targeting TP53INP2, which will offer a fresh research orientation for the diagnosis of CC.

BMC Genomics 2021; 22:768. [PMID: 34706645 PMCID: PMC8555003 DOI: 10.1186/s12864-021-07880-z] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Accepted: 06/18/2021] [Indexed: 12/18/2022] Open
Abstract
OBJECTIVE Colon cancer (CC) is one of the most common cancers whose progression is regulated by a number of factors, including circular RNAs (circRNAs). Nonetheless, circ_0038718 is a novel circRNA, and its regulatory mechanism in CC remains unclear. METHODS Real-time quantitative PCR (qRT-PCR) was performed to detect the expression of circ_0038718, miR-195-5p and Axin2. Western blot was conducted to determine the protein expression of Axin2 and the key proteins on Wnt/β-catenin signaling pathway. Oligo (dT) 18 primers and RNase R were employed to identify the circular features of circ_0038718, and the location of circ_0038718 in cells was detected via nucleocytoplasmic separation. Dual-luciferase reporter assay and RNA binding protein immunoprecipitation experiment were carried out to investigate the molecular mechanism of circ_0038718/miR-195-5p/Axin2. Additionally, MTT assay was conducted to assess cell proliferation; Transwell assay was performed to evaluate cell migration and invasion, respectively. The effect of circ_0038718 on CC tumor growth was tested through tumor formation in nude mice. RESULTS circ_0038718 was highly expressed in CC and could sponge miR-195-5p in cytoplasm. Silencing circ_0038718 suppressed the proliferative, migratory and invasive abilities of CC cells, while the promoting effect of high circ_0038718 expression on CC cells was reversed upon miR-195-5p over-expression. Axin2 was a downstream target of miR-195-5p and could regulate the Wnt/β-catenin signaling pathway. Axin2 expression was modulated by circ_0038718/miR-195-5p. Knockdown of Axin2 could also attenuate the promoting effect of high circ_0038718 expression on CC cell malignant progression, thus inhibiting tumor growth. CONCLUSION circ_0038718 is able to facilitate CC cell malignant progression via the miR-195-5p/Axin2 axis, which will provide a new idea for finding a novel targeted treatment of CC.

Abstract
OBJECTIVE To explore the role of miR-671-5p in regulating the migration and invasion of osteosarcoma and the underlying mechanisms. METHODS The differentially expressed microRNAs (miRNAs) in osteosarcoma were screened in the NCBI online database, and the target proteins of these miRNAs were predicted and their functions were analyzed. Osteosarcoma cells were transfected with a plasmid overexpressing miR-671-5p, and the transfection efficiency was assessed using quantitative real-time PCR (qRT-PCR). The changes in the migration and invasion of the transfected cells were examined with Transwell assay, and the expressions of proteins related with epithelial-mesenchymal transition (EMT) were detected using Western blotting. Dual-luciferase reporter assay was performed to determine whether the 3'UTR of SMAD3 contained a targeted binding site of miR-671-5p. RESULTS MiR-671-5p was significantly down-regulated in both osteosarcoma tissues and osteosarcoma cells (P < 0.05). The osteosarcoma cells overexpressing miR-671-5p showed significantly reduced migration and invasion abilities (P < 0.05) with obviously lowered expressions of EMT-related proteins (P < 0.05). SMAD3 was highly expressed in osteosarcoma cells (P < 0.05), and dual-luciferase reporter assay confirmed the presence of a targeted binding site between miR-671-5p and the 3'UTR of SMAD3 (P < 0.05). In osteosarcoma cells transfected with a SMAD3-overexpressing plasmid (P < 0.05), the high expression of SMAD3 significantly inhibited by miR-671-5p overexpression (P < 0.05). Transwell assay demonstrated that SMAD3 overexpression significantly promoted the migration and invasion of osteosarcoma cells (P < 0.05), and while miR-671-5p overexpression obviously reversed this effect (P < 0.05). CONCLUSION MiR-671-5p can inhibit the invasion and migration of osteosarcoma cells by negatively regulating SMAD3.

Abstract
Objective This study aimed to discover the ceRNAs network in the pathophysiological development of human colorectal cancer (CRC) and to screen biomarkers for target therapy and prognosis by using integrated bioinformatics analysis. Methods Data on gene expressions of mRNAs, miRNAs, and circRNAs and clinical information were downloaded from The Cancer Genome Atlas and Gene Expression Omnibus databases, respectively. Differentially expressed mRNAs (DEmRNAs) were identified by using the DESeq2 package of R software. Functional enrichment analysis was conducted using the ClusterProfiler package of R software. The protein–protein interaction (PPI) network was shown by the STRING website. Survival analysis of hub genes was performed using the survival package in R software. Interactions among hub genes, differentially expressed miRNAs (DEmiRNAs), and differentially expressed circRNAs (DEcircRNAs) were used to construct the ceRNAs network. Results A total of 412 DEmRNAs including 82 upregulated and 330 downregulated genes were screened out between 473 CRC and 41 normal samples. Two hundred and sixty DEcircRNAs including 253 upregulated and 7 downregulated genes were altered between 23 CRC and 23 normal samples. One hundred and ninety DEmiRNAs including 82 upregulated and 108 downregulated genes were obtained between 450 CRC and 8 normal samples. A ceRNAs and PPI network were successfully constructed, and TIMP1 associated with prognosis was employed. Conclusion The present study identified a novel circRNAs-miRNAs-mRNA ceRNAs network, which implied that TIMP1 and related miRNAs, circRNAs were potential biomarkers underlying the development of CRC, providing new insights for survival predictions and therapeutic targets.

Abstract
Colon cancer is one of most common cancers. The progression of various cancers is driven by miRNA-570. The role of miRNA-570 in the progression of colon cancer remains unclear. We aimed to investigate the clinical function of miR-570 and its impact on colon cancer cells. We evaluated the expression of miR-570 in colon cancer cells and analyzed its influence on the various clinical parameters. The Kaplan-Meier curve was plotted to understand the clinical role of miR-570. Cox regression analysis was performed to predict the prognostic factors in colon cancer. The Cell Counting Kit-8 was used to investigate the effect of miR-570 on cell proliferation. The transwell migration assay was performed to quantify cell migration and invasion. The quantitative real-time polymerase chain reaction technique was used to analyze the sample system. The results revealed that the level of miR-570 expression in colon cancer tissues and cell lines was low. The abnormal expression of miR-570 was associated with tumor size, extent of differentiation, lymph node metastasis, and tumor-node-metastasis stages. Downregulation of miR-570 indicated poor overall survival (OS), poor relapse-free survival, and unfavorable cancer-specific survival (CSS) rates in patients with colon cancer. The results from Cox regression analysis revealed that miR-570 expression could be used as an independent prognostic biomarker for OS and CSS in colon cancer. Overexpression of miR-570 can potentially result in the inhibition of cell proliferation, migration, and invasion. The results proved that miR-570 could potentially function as a tumor suppressor and a potential prognostic factor in patients with colon cancer.

Abstract
The pivotal role of dysregulated miRNAs in development of papillary thyroid carcinoma has been emphasized in recent research. miR-671-5p was previously documented to function as a tumor suppressor. However, the role and mechanism of miR-671-5p in progression of papillary thyroid carcinoma remain to be further studied. Data from functional assays indicated that forced expression of miR-671-5p decreased cell viability, repressed cell proliferation, migration, and invasion in papillary thyroid carcinoma cells. In vivo study showed that miR-671-5p overexpression inhibited tumor growth, downregulated Ki67, and decreased tumor volume and weight. Tripartite motif containing 14 (TRIM14) was verified as downstream target of miR-671-5p. The expression of TRIM14 was suppressed by miR-671-5p in papillary thyroid carcinoma. Overexpression of TRIM14 increased cell viability, and promoted the proliferation, migration, and invasion of papillary thyroid carcinoma. Moreover, TRIM14 counteracted the suppressive effect of miR-671-5p overexpression on papillary thyroid carcinoma cell growth.

[PMID: 33958893 PMCID: PMC8096343 DOI: 10.2147/cmar.s299715] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Accepted: 04/15/2021] [Indexed: 12/16/2022] Open
Abstract
Introduction Emerging evidence has revealed that long noncoding RNA (lncRNA) play important role in almost all kinds of human cancers. LINC00908 has been reported to be involved in the development of prostate cancer, colorectal cancer and gastric cancer which was functioned as an oncogene. However, the potential biology role and molecular mechanism of LINC00908 in diffuse large B-cell lymphoma are still unclear. Methods LINC00908 and miR-671-5p expression were evaluated in DLBCL tissues and cell lines using RT-qPCR. CCK-8 and transwell assay were used to analyze the in vitro role of LINC00908 in DLBCL progression. The xenograft model was used to explore the in vivo role of LINC00908 in DLBCL growth. The physical interaction between LINC00908 and miR-671-5p was confirmed using bioinformatics analysis and a dual luciferase assay, RIP and RNA pull down. Results The expression of LINC00908 was markedly up-regulated in diffuse large B-cell lymphoma tissues and cell lines, and the decreased expression of LINC00908 significantly inhibited diffuse large B-cell lymphoma cell proliferation and invasion. Then, we revealed that LINC00908 directly interacted with miR-671-5p, which was down-regulated in diffuse large B-cell lymphoma cells and highly expressed with LINC00908 knockdown. Moreover, luciferase reporter assays and RNA immunoprecipitation (RIP) assay further proved that miR-671-5p is a direct target of LINC00908 in diffuse large B-cell lymphoma cells. Rescue experiments were also performed, and we confirmed that LINC00908 acts as an oncogene role in diffuse large B-cell lymphoma through miR-671-5p. Finally, the influence of LINC00908 silence significantly inhibited diffuse large B-cell lymphoma growth in vivo. Conclusion LINC00908 promotes malignancy of diffuse large B-cell lymphoma through regulating miR-671-5p.

Circ_0049447 acts as a tumor suppressor in gastric cancer through reducing proliferation, migration, invasion, and epithelial-mesenchymal transition. Chin Med J (Engl) 2021; 134:1345-1355. [PMID: 33883408 PMCID: PMC8183756 DOI: 10.1097/cm9.0000000000001494] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Although increasing abnormal expression of circular RNAs (circRNAs) has been revealed in various cancers, there were a small number of studies about circRNAs in gastric cancer (GC). Here, we explored the expression and function of a novel circRNA, circ_0049447, in GC. METHODS A total of 80 GC tissues and non-tumorous tissues were collected from the First Affiliated Hospital of China Medical University. And all cells were cultured with 10% fetal bovine serum and incubated at 37°C and 5% CO2. The expression of circ_0049447 was quantified by real-time polymerase chain reaction. The biological function of circ_0049447 on proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) was evaluated by cell counting kit-8 (CCK-8), colony formation assay, transwell migration and invasion assay, and Western blotting. Luciferase report assay was used to verify the direct binding between circ_0049447 and predicted microRNA (miRNA). Furthermore, a xenograft mouse model was used to validate the function of circ_0049447 in vivo. RESULTS We demonstrated that circ_0049447 was downregulated in GC (P < 0.001). The area under the receiver operating characteristic curve reached 0.838, while sensitivity was 82.3% and specificity was 77.2%. CCK-8 and colony formation assay showed that overexpression of circ_0049447 could inhibit the proliferation (P < 0.05). Transwell migration and invasion assay showed upregulated circ_0049447 could impede migration in GC cells (P < 0.05). In addition, overexpression of circ_0049447 could impede GC cell EMT. Upregulation of miR-324-5p in GC specimens and direct binding between miR-324-5p with circ_0049447 proven by luciferase reporter assay indicated that circ_0049447 may inhibit GC by sponging certain miRNA. CONCLUSION Circ_0049447 acts as a tumor suppressor in GC through reducing proliferation, migration, invasion, and EMT, and it is a promising biomarker for diagnosis.

Abstract
LINC01207 is involved in the progression of some cancers. This study was designed to delve into the biological function and mechanism of LINC01207 in gastric cancer. qPCR was adopted to examine the expression levels of LINC01207, miR-671-5p, DDX5 mRNA in gastric cancer tissues and cells. After LINC01207 was overexpressed or depleted, MTT and BrdU assays were conducted to detect cell proliferation. Transwell assay was employed to detect cell migration and invasion. Western blot was used to detect the expression of DDX5 protein in cells. Bioinformatics analysis, luciferase reporter assay and RNA pull-down assay were performed to predict and validate the binding site between miR-671-5p and LINC01207 or DDX5. LINC01207, DDX5 mRNA were up-regulated in gastric cancer, while miR-671-5p was down-regulated; high expression of LINC01207 and transfection of miR-671-5p inhibitors facilitated the proliferation of gastric cancer cells; however, knocking down LINC01207 and the overexpression of miR-671-5p mimics had opposite biological effects. LINC01207 and miR-671-5p were interacted and miR-671-5p was negatively regulated by LINC01207. MiR-671-5p could reverse the function of LINC01207. DDX5 was a downstream target of miR-671-5p and was positively modulated by LINC01207. LINC01207 promotes the proliferation and metastasis of gastric cancer cells by regulating miR-671-5p/DDX5 axis.

Abstract
MiR-1253 has been reported to play vital roles in a variety of cancers. However, its function in the progression and prognosis of colon cancer remains unclear. Here, the clinical significance and biological function of miR-1253 in the development of colon cancer was investigated. The expression of miR-1253 was identified in colon cancer tissues and cell lines by qRT-PCR. The prognostic value of miR-1253 was evaluated by Kaplan-Meier and Cox regression analysis. The roles of miR-1253 in regulating cell proliferation, migration, and invasion of colon cancer were evaluated in vitro by CCK8 and Transwell assay. It was found that miR-1253 was significantly downregulated in colon cancer tissues and cell lines (P < 0.001). The downregulation of miR-1253 was associated with the TNM stage (P = 0.007) and lymph node metastasis (P = 0.037) of patients. MiR-1253 (HR factor = 2.564, 95% CI = 1.077-6.107, P = 0.033) and TNM stage (HR factor = 2.899, 95% CI = 1.024-8.205, P = 0.045) were identified as independent factors that can predict the prognosis of patients. Functionally, miR-1253 acts as a tumor suppressor that inhibited cell proliferation, migration, and invasion of colon cancer through targeting EZH2. MiR-1253 was identified as a prognostic biomarker and a tumor suppressor of colon cancer.

Circular RNA profiles and the potential involvement of down-expression of hsa_circ_0001360 in cutaneous squamous cell carcinogenesis. FEBS Open Bio 2021; 11:1209-1222.

Abstract
Circular RNAs (circRNAs) act as sponges of noncoding RNAs and have been implicated in many pathophysiological processes, including tumor development and progression. However, their roles in cutaneous squamous cell carcinoma (cSCC) are not yet well understood. This study aimed to identify differentially expressed circRNAs and their potential functions in cutaneous squamous cell carcinogenesis. The expression profiles of circRNAs in three paired cSCC and adjacent nontumorous tissues were detected with RNA sequencing and bioinformatics analysis. The candidate circRNAs were validated by PCR, Sanger sequencing and quantitative RT‐PCR in another five matched samples. The biological functions of circRNAs in SCL‐1 cells were assessed using circRNA silencing and overexpression, 3‐(4,5‐dimethylthiazol‐2‐yl)‐5‐(3‐carboxymethoxyphenyl)‐2‐(4‐sulfophenyl)‐2H‐tetrazolium inner salt (MTS), flow cytometry, transwell and colony formation assays. In addition, the circRNA–miRNA–mRNA interaction networks were predicted by bioinformatics. In summary, 1115 circRNAs, including 457 up‐regulated and 658 down‐regulated circRNAs (fold change ≥ 2 and P < 0.05), were differentially expressed in cSCC compared with adjacent nontumorous tissues. Of four selected circRNAs, two circRNAs (hsa_circ_0000932 and hsa_circ_0001360) were confirmed to be significantly decreased in cSCC using PCR, Sanger sequencing and quantitative RT‐PCR. Furthermore, hsa_circ_0001360 silencing was found to result in a significant increase of the proliferation, migration and invasion but a significant decrease of apoptosis in SCL‐1 cells in vitro, whereas hsa_circ_0001360 overexpression showed the opposite regulatory effects. hsa_circ_0001360 was predicted to interact with five miRNAs and their corresponding genes. In conclusion, circRNA dysregulation may play a critical role in carcinogenesis of cSCC, and hsa_circ_0001360 may have potential as a biomarker for cSCC.

Abstract
Prostate cancer (PCa) is the second cause of death due to malignancy among men, and metastasis is the leading cause of mortality in patients with PCa. MicroRNAs (miRNAs) play important regulatory roles in tumor development and metastasis. Here, we identified 13 miRNAs related to PCa metastasis by bioinformatics analysis. Moreover, we found that miR-671-5p was increased in metastatic PCa tissues, and its high expression indicated poor prognosis of PCa. MiR-671-5p could facilitate PCa cells proliferation, migration, and invasion in vitro and vivo. We confirmed that miR-671-5p directly bound to the 3’ untranslated regions of NFIA mRNA, and NFIA directly bound to the CRYAB promoter. High expression of NFIA and CRYAB negatively correlated with the advanced clinicopathological characteristics and metastasis status of PCa patients. Our study demonstrated that miR-671-5p promoted PCa development and metastasis by suppressing NFIA/ CRYAB axis.

Abstract
MicroRNA (miR)-628-5p serves as an antitumor gene in a variety of cancers; however, the role of miR-628-5p in colorectal cancer remains largely unclear. The purpose of this study was to investigate the role and mechanism of miR-628-5p in colorectal cancer. Reverse transcription-quantitative PCR (RT-qPCR), colony formation assays and flow cytometric analysis were used to determine the expression levels of miR-628-5p in colorectal cancer tissues and cell lines, and the proliferative ability of colorectal cancer cells. TargetScan version 7.2 and dual-luciferase reporter assay were performed to predict and confirm miR-628-5p target genes. The expression levels of cyclin D1 (CCND1) and related genes were determined using RT-qPCR or/and western blotting analysis. miR-628-5p mimics and CCND1 plasmids were used to overexpress miR-628-5p and CCND1; it was demonstrated that the expression levels of miR-628-5p were significantly downregulated in colorectal cancer tissues and cell lines. miR-628-5p mimic-transfected cells inhibited the proliferation and induced apoptosis of HT-29 cells. CCND1, a downstream effector of miR-628-5p, promoted the proliferation and suppressed apoptosis of HT-29 cells, and the effects were reversed by miR-628-5p mimics. In conclusion, the present study suggested that colorectal cancer progression may be regulated through the miR-628-5p/CCND1 axis, and miR-628-5p could be used as a potential diagnostic and prognostic biomarker for colorectal cancer.
