The critical role and functional mechanism of microRNA-146a in doxorubicin-induced apoptosis in breast cancer cells. NUCLEOSIDES, NUCLEOTIDES & NUCLEIC ACIDS 2024:1-12. [PMID: 38531028 DOI: 10.1080/15257770.2024.2330592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Accepted: 03/06/2024] [Indexed: 03/28/2024]
Abstract
BACKGROUND Breast cancer among women is the most frequently diagnosed cancer and the leading cause of death worldwide. There many advances in diagnosing and treating this disease, early diagnosis and treatment are still a significant challenge in the early stages. In recent years, microRNAs have attracted much attention in cancer diagnosis and treatment. However, the role of miR-146a in breast cancer is still controversial. We aimed to investigate the roles of miR-146a in apoptosis in breast cancer cells. METHODS A microarray dataset from the GEO database was selected, and using the GEO2R tool, the gene expression profile of this dataset was extracted. Then, the target scan database was used to explore the miR-146a target genes. The link between the signaling pathways was collected. We used miR-146a mimic, which was transfected to the MCF-7 cells to investigate the miR-146a roles in the apoptosis. The expression levels of miR-146a and BAX, BCL-2, and p-21(most essential genes in the apoptosis) were quantified by qPCR and western blot analysis. RESULTS Our findings indicated that doxorubicin induces miR-146a expression. In addition, overexpression of miR-146a affected MCF-7 cell viability, induced apoptosis, and led to reduced expression levels of BCL-2 and P-21, as well as increased BAX expression levels. CONCLUSION Considering the role of doxorubicin in inducing apoptosis and increasing the expression of miR-146a, it can be suggested that this miR is involved in inducing apoptosis in BC cells. In addition, miR-146a can be considered a therapeutic candidate.

Abstract
Functional inactivation of wild-type p53 is a major trait of cancerous cells. In many cases, such inactivation occurs by either TP53 gene mutations or due to overexpression of p53 binding partners. This review focuses on an overexpressed p53 binding partner called mortalin, a mitochondrial heat shock protein that sequesters both wild-type and mutant p53 in malignant cells due to changes in subcellular localization. Clinical evidence suggests a drastic depletion of the overall survival time of cancer patients with high mortalin expression. Therefore, mortalin-p53 sequestration inhibitors could be game changers in improving overall survival rates. This review explores the consequences of mortalin overexpression and challenges, status and strategies for accelerating drug discovery to suppress mortalin-p53 sequestration.

Abstract
It has been reported that lncRNA GAS5 can inhibit LPS-induced inflammation, indicating its involvement in sepsis. We observed the downregulation of GAS5 in plasma of sepsis patients. In addition, expression levels of GAS5 were positively correlated with the expression levels of miR-214. In cardiomyocytes, overexpression of GAS5 upregulated the expression of miR-214, while its knockdown resulted in decreased expression levels of miR-124. Methylation-specific PCR (MSP) revealed that GAS5 negatively regulated the methylation of miR-124. Cell apoptosis showed that overexpression of GAS5 and miR-214 suppressed the apoptosis of cardiomyocytes induced by LPS. In addition, overexpression of miR-214 also reduced the enhancing effects of silencing of GAS5 on cell apoptosis. Therefore, GAS5 may upregulate miR-214 through methylation pathway to inhibit the apoptosis of cardiomyocytes in sepsis.

Abstract
Breast cancer has been reported as the most common cancer in women globally, with 2.26 million new cases in 2020. While anthracyclines are the first-line drug for breast cancer, they cause a variety of adverse reactions and drug resistance, especially for triple-negative breast cancer, which can lead to poor prognosis, high relapse, and mortality rate. MicroRNAs (miRNAs) have been shown to be important in the initiation, development and metastasis of malignancies and their abnormal transcription levels may influence the efficacy of anthracyclines by participating in the pathologic mechanisms of breast cancer. Therefore, it is essential to understand the exact role of miRNAs in the treatment of breast cancer with anthracyclines. In this review, we outline the mechanisms and signaling pathways involved in miRNAs in the treatment of breast cancer using anthracyclines. The role of miRNA in the diagnosis, prognosis and treatment of breast cancer patients is discussed, along with the involvement of miRNAs in chemotherapy for breast cancer.

Abstract
MicroRNAs (miRNAs) are endogenously expressed, non-coding RNA molecules that mediate the post-transcriptional repression and degradation of mRNAs by targeting their 3′ untranslated region (3′-UTR). Thousands of miRNAs have been identified since their first discovery in 1993, and miR-214 was first reported to promote apoptosis in HeLa cells. Presently, miR-214 is implicated in an extensive range of conditions such as cardiovascular diseases, cancers, bone formation and cell differentiation. MiR-214 has shown pleiotropic roles in contributing to the progression of diseases such as gastric and lung cancers but may also confer cardioprotection against excessive fibrosis and oxidative damage. These contrasting functions are achieved through the diverse cast of miR-214 targets. Through silencing or overexpressing miR-214, the detrimental effects can be attenuated, and the beneficial effects promoted in order to improve health outcomes. Therefore, discovering novel miR-214 targets and understanding how miR-214 is dysregulated in human diseases may eventually lead to miRNA-based therapies. MiR-214 has also shown promise as a diagnostic biomarker in identifying breast cancer and coronary artery disease. This review provides an up-to-date discussion of miR-214 literature by describing relevant roles in health and disease, areas of disagreement, and the future direction of the field.

Abstract
Breast cancer is the most frequently diagnosed cancer among females. Gene expression profiling methods have shown the deregulation of several genes in breast cancer samples and have confirmed the heterogeneous nature of breast cancer at the genomic level. microRNAs (miRNAs) are among the recently appreciated contributors in breast carcinogenic processes. These small-sized transcripts have been shown to partake in breast carcinogenesis through modulation of apoptosis, autophagy, and epithelial-mesenchymal transition. Moreover, they can confer resistance to chemotherapy. Based on the contribution of miRNAs in almost all fundamental aspects of breast carcinogenesis, therapeutic intervention with their expression might affect the course of this disorder. Moreover, the presence of miRNAs in the peripheral blood of patients potentiates these transcripts as tools for non-invasive diagnosis of breast cancer.

Abstract
BACKGROUND Chemotherapy is one of the most common treatment options for breast cancer (BC) patients. However, about half of the BC patients are chemotherapeutic resistant. Doxorubicin (DOX) is considered as one of the first line drugs in the treatment of BC patients whose function is negatively affected by multi drug resistance. Due to the severe side effects of DOX, it is very important to diagnose the DOX resistant BC patients. Therefore, assessment of molecular mechanisms involved in DOX resistance can improve the clinical outcomes in BC patients by introducing the novel therapeutic and diagnostic molecular markers. MicroRNAs (miRNAs) as members of the non-coding RNAs family have pivotal roles in various cellular processes including cell proliferation and apoptosis. Therefore, aberrant miRNAs functions and expressions can be associated with tumor progression, metastasis, and drug resistance. Moreover, due to miRNAs stability in body fluids, they can be considered as non-invasive diagnostic markers for the DOX response in BC patients. MAIN BODY In the present review, we have summarized all of the miRNAs that have been reported to be associated with DOX resistance in BC for the first time in the world. CONCLUSIONS Since, DOX has severe side effects; it is required to distinguish the non DOX-responders from responders to improve the clinical outcomes of BC patients. This review highlights the miRNAs as pivotal regulators of DOX resistance in breast tumor cells. Moreover, the present review paves the way of introducing a non-invasive panel of prediction markers for DOX response among BC patients.

Abstract
Doxorubicin is a chemotherapeutic agent that inhibits topoisomerase II, intercalates within DNA base pairs and results in oxidative DNA damage, thus inducing cell apoptosis. Although it is effective in the treatment of a wide range of human cancers, the emergence of resistance to this drug can increase tumour growth and impact patients' survival. Numerous molecular mechanisms and signalling pathways have been identified that induce resistance to doxorubicin via stimulation of cell proliferation, cell cycle switch and preclusion of apoptosis. A number of microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) have also been identified that alter sensitivity to doxorubicin. Understanding the particular impact of these non-coding RNAs in conferring resistance to doxorubicin has considerable potential to improve selection of chemotherapeutic regimens for cancer patients. Moreover, modulation of expression of these transcripts is a putative strategy for combating resistance. In the current paper, the influence of miRNAs and lncRNAs in the modification of resistance to doxorubicin is discussed.

Long non-coding RNA MEG3 silencing and microRNA-214 restoration elevate osteoprotegerin expression to ameliorate osteoporosis by limiting TXNIP. J Cell Mol Med 2021; 25:2025-2039.

Abstract
Studies have shown that long non-coding RNA (lncRNA) MEG3 plays a key role in osteoporosis (OP), but its regulatory mechanism is somewhat incompletely clear. Here, we intend to probe into the mechanism of MEG3 on OP development by modulating microRNA-214 (miR-214) and thioredoxin-interacting protein (TXNIP). Rat models of OP were established. MEG3, miR-214 and TXNIP mRNA expression in rat femoral tissues were detected, along with TXNIP, OPG and RANKL protein expression. BMD, BV/TV, Tb.N and Tb.Th in tissue samples were measured. Ca, P and ALP contents in rat serum were also determined. Primary osteoblasts were isolated and cultured. Viability, COL-I, COL-II and COL-Χ mRNA expression, PCNA, cyclin D1, OCN, RUNX2 and osteolix protein expresion, ALP content and activity, and mineralized nodule area of rat osteoblasts were further detected. Dual-luciferase reporter gene and RNA-pull down assays verified the targeting relationship between MEG3, miR-214 and TXNIP. MEG3 and TXNIP were up-regulated while miR-214 was down-regulated in femoral tissues of OP rats. MEG3 silencing and miR-214 overexpression increased BMD, BV/TV, Tb.N, Tb.Th, trabecular bone area, collagen area and OPG expression, and down-regulated RANKL of femoral tissues in OP rats. MEG3 silencing and miR-214 overexpression elevated Ca and P and reduced ALP in OP rat serum, elevated osteoblast viability, differentiation ability, COL-I and COL-Χ expression and ALP activity, and reduced COL-II expression of osteoblasts. MEG3 specifically bound to miR-214 to regulate TXNIP. MEG3 silencing and miR-214 overexpression promote proliferation and differentiation of osteoblasts in OP by down-regulating TXNIP, which further improves OP.

Abstract
The tumor suppressor protein p53 participates in the control of key biological functions such as cell death, metabolic homeostasis and immune function, which are closely related to various diseases such as tumors, metabolic disorders, infection and neurodegeneration. The p53 gene is also mutated in approximately 50% of human cancer cells. Mutant p53 proteins escape from the ubiquitination-dependent degradation, gain oncogenic function and promote the carcinogenesis, malignant progression, metastasis and chemoresistance. Therefore, the stability of both wild type and mutant p53 needs to be precisely regulated to maintain normal functions and targeting the p53 stability is one of the therapeutic strategies against cancer. Here, we focus on compound-induced degradation of p53 by both the ubiquitination-dependent proteasome and autophagy-lysosome degradation pathways. We also review other posttranslational modifications which control the stability of p53 and the biological functions involved in these processes. This review provides the current theoretical basis for the regulation of p53 abundance and its possible applications in different diseases.

Abstract
BACKGROUND Bladder cancer (BCa) is the ninth frequent and 13th leading cause of cancer related deaths in the world which is mainly observed among men. There is a declining mortality rates in developed countries. Although, the majority of BCa patients present Non-Muscle-Invasive Bladder Cancer (NMIBC) tumors, only 30% of patients suffer from muscle invasion and distant metastases. Radical cystoprostatectomy, radiation, and chemotherapy have proven to be efficient in metastatic tumors. However, tumor relapse is observed in a noticeable ratio of patients following the chemotherapeutic treatment. Non-coding RNAs (ncRNAs) are important factors during tumor progression and chemo resistance which can be used as diagnostic and prognostic biomarkers of BCa. MAIN BODY In present review we summarized all of the lncRNAs and miRNAs associated with chemotherapeutic resistance in bladder tumor cells. CONCLUSIONS This review paves the way of introducing a prognostic panel of ncRNAs for the BCa patients which can be useful to select a proper drug based on the lncRNA profiles of patients to reduce the cytotoxic effects of chemotherapy in such patients.

In the present study, we found that miR-532-5p was significantly downregulated in both OS tissues and cell lines. The low level of miR-532-5p was associated with advance clinical stage and poor overall survival in patient with OS. The functional experiments implied that upregulation of miR-532-5p restrained OS U2OS cell growth and metastatic ability in vitro; induced apoptosis, and impaired OS cell growth in vivo. Mechanistically, chemokine (C-X-C Motif) ligand 2 (CXCL2) was proved as a target gene of miR-532-5p. The inhibitory effects of miR-532-5p on OS cell were rescued by CXCL2 overexpression. Altogether, we demonstrated that miR-532-5p exerted tumor-inhibitory functions in OS cell via regulating CXCL2.

Abstract
COP1, an E3 ubiquitin ligase, has been demonstrated to play a vital role in the regulation of cell proliferation, apoptosis and DNA repair. Accumulated evidence has revealed that COP1 is involved in carcinogenesis via targeting its substrates, including p53, c-Jun, ETS, β-catenin, STAT3, MTA1, p27, 14-3-3σ, and C/EBPα, for ubiquitination and degradation. COP1 can play tumor suppressive and oncogenic roles in human malignancies, urging us to summarize the functions of COP1 in tumorigenesis. In this review, we describe the structure of COP1 and its known substrates. Moreover, we dissect the function of COP1 by physiological (mouse models), pathological (human tumor specimens) and biochemical (ubiquitin substrates) Evidence. Furthermore, we discuss COP1 as a potential therapeutic target for cancer therapy.

Abstract
Objective We explored the role and mechanism of miR-214 involvement in the progression of diffuse large B-cell lymphoma (DLBCL). Methods The expression levels of miR-214 and PD-L1 in human DLBCL cell lines and in tissue samples from patients with DLBCL were determined using quantitative RT-PCR. The dual-luciferase reporter assay was employed to determine the correlation between the expressions of miR-214 and PD-L1. Cell viability, invasiveness and apoptosis were respectively examined in cells of the DLBCL line OCI-Ly3 using CCK-8, transwell and flow cytometry assays. The expression level of PD-L1 was determined via immunoblotting. Inflammatory cytokine secretion was determined via enzyme-linked immune sorbent assay (ELISA). Results miR-214 was downregulated and PD-L1 was upregulated in DLBCL tissues and cell lines in comparison to normal adjacent tissues or normal B-cell. This indicates a negative correlation in the expression levels. Overexpression of miR-214 inhibited cell viability and invasion and induced apoptosis of OCI-Ly3 cells. Moreover, miR-214 was shown to target PD-L1 mRNA by binding to its 3′-untranslated region (UTR). Knockdown of PD-L1 attenuated the malignant phenotype of OCI-Ly3 cells. Overexpression of miR-214 inhibited tumor growth by targeting PD-L1 in vivo. Conclusion By targeting PD-L1, miR-214 regulates the progression of DLBCL in vitro and in vivo.

Abstract
Imbalance between amyloid-beta (Aβ) peptide synthesis and clearance results in Aβ deregulation. Failure to clear these peptides appears to cause the development of Alzheimer's disease (AD). In recent years, microRNAs have become established key regulators of biological processes that relate among others to the development and progression of neurodegenerative diseases, such as AD. This review article gives an overview on microRNAs that are involved in the Aβ cascade and discusses their inhibitory impact on their target mRNAs whose products participate in Aβ clearance. Understanding of the mechanism of microRNA in the associated signal pathways could identify novel therapeutic targets for the treatment of AD.

Abstract
MicroRNAs (miRNAs) are a class of endogenous noncoding genes that regulate gene expression at the posttranscriptional level. In recent decades, miRNAs have been reported to play important roles in tumor growth and metastasis, while some reported functions of a specific miRNA in tumorigenesis are contradictory. In this study, we reevaluated the role of miR-214, which has been reported to serve as an oncogene or anti-oncogene in breast cancer metastasis. We found that miR-214 inhibited breast cancer via targeting RNF8, a newly identified regulator that could promote epithelial-mesenchymal transition (EMT). Specifically, the survival rate of breast cancer patients was positively correlated with miR-214 levels and negatively correlated with RNF8 expression. The overexpression of miR-214 inhibited cell proliferation and invasion of breast cancer, while suppression of miR-214 by chemically modified antagomir enhanced the proliferation and invasion of breast cancer cells. Furthermore, miR-214 could modulate the EMT process via downregulating RNF8. To our knowledge, this is the first report that reveals the role of the miR-214-RNF8 axis in EMT, and our results demonstrate a novel mechanism for miR-214 acting as a tumor suppressor through the regulation of EMT.

Abstract
To protect tissues and the organism from disease, potentially harmful cells are removed through programmed cell death processes, including apoptosis and necroptosis. These types of cell death are critically controlled by microRNAs (miRNAs). MiRNAs are short RNA molecules that target and inhibit expression of many cellular regulators, including those controlling programmed cell death via the intrinsic (Bcl-2 and Mcl-1), extrinsic (TRAIL and Fas), p53-and endoplasmic reticulum (ER) stress-induced apoptotic pathways, as well as the necroptosis cell death pathway. In this review, we discuss the current knowledge of apoptosis and necroptosis pathways and how these are impaired in cancer cells. We focus on how miRNAs disrupt apoptosis and necroptosis, thereby critically contributing to malignancy. Understanding which and how miRNAs and their targets affect cell death pathways could open up novel therapeutic opportunities for cancer patients. Indeed, restoration of pro-apoptotic tumor suppressor miRNAs (apoptomiRs) or inhibition of oncogenic miRNAs (oncomiRs) represent strategies that are currently being trialed or are already applied as miRNA-based cancer therapies. Therefore, better understanding the cancer type-specific expression of apoptomiRs and oncomiRs and their underlying mechanisms in cell death pathways will not only advance our knowledge, but also continue to provide new opportunities to treat cancer.

Abstract
Conditioned medium (CM) and microvesicles (MVs) are produced using different protocols: CM is collected following 12-96 h of cell culture without renewal of tissue culture medium, while MVs are collected after overnight cell culture. For future comparative studies in regenerative medicine looking at the efficacy of CM and MVs, it is important to understand how the quality of cell secretions is affected by culture. The aim of this study was to evaluate whether the duration of culturing influences the micro-RNAs (miRNAs) cargo of equine amniotic mesenchymal cells (AMCs) and their MVs. The analysis identified 990 miRNAs. After one night, there were 347 differently expressed (DE)-miRNAs between MVs and cells, whereas after four nights there were 359. About 58.3% of the DE-miRNAs were shared between samples produced under the two conditions. The comparison between miRNA content in AMC cells cultured for one night versus four nights showed eight DE-Equus caballus (eca)-miRNAs, which target genes were involved in immune response to external stimulus, inflammatory response, and production of reactive oxygen species. Comparing MVs isolated from one or four nights, four DE-miRNAs that target genes regulating cell cycle progression and production of reactive oxygen species were found, but only eca-miR-214 was enriched in the MVs after four nights. In conclusion, after 4 days of cell culture, the profile of AMC miRNAs was altered, indicating a probable phenotypic transition versus a new cell culture environment and aging. After this time, MVs accumulated eca-miR-214, which may help cells survive or adapt to new culture conditions.

Abstract
Prostate cancer is the most commonly diagnosed cancer in men with African American men disproportionally suffering from the burden of this disease. Biomarkers that could discriminate indolent from aggressive and drug resistance disease are lacking. MicroRNAs are small non-coding RNAs that affect numerous physiological and pathological processes, including cancer development and have been suggested as biomarkers and therapeutic targets. In the present study, we investigated the role of miR-214 on prostate cancer cell survival/migration/invasion, cell cycle regulation, and apoptosis. miR-214 was differentially expressed between Caucasian and African American prostate cancer cells. Importantly, miR-214 overexpression in prostate cancer cells induced apoptosis, inhibiting cell proliferation and colony forming ability. miR-214 expression in prostate cancer cells also inhibited cell migration and 3D spheroid invasion. Mechanistically, miR-214 inhibited prostate cancer cell proliferation by targeting protein tyrosine kinase 6 (PTK6). Restoration of PTK6 expression attenuated the inhibitory effect of miR-214 on cell proliferation. Moreover, simultaneous inhibition of PTK6 by ibrutinib and miR-214 significantly reduced cell proliferation/survival. Our data indicates that miR-214 could act as a tumor suppressor in prostate cancer and could potentially be utilized as a biomarker and therapeutic target.

Abstract
Differentiation antagonizing non-protein coding RNA (DANCR) is a valuable long noncoding RNA (lncRNA) that involves in the progress of various cancers. However, the functions of DANCR in endometrial carcinoma (EC) have not been validated. In the present study, we aimed to evaluate the roles of DANCR in EC and explore the underlying mechanism. Expression patterns of DANCR in EC specimens and normal control specimens were determined using qRT-PCR. DANCR was knocked down in EC cell lines (AN3CA and HEC-1B) through transfection with small interfering RNA (siRNA) targeting DANCR (si-DANCR). Cell proliferation was examined using the cell counting kit-8 (CCK-8) assay. Cell apoptosis was measured by flow cytometry. Online software starBase was used to predict the target gene of DANCR. Luciferase reporter assay was carried out to confirm the association between DANCR and the predicted target microRNA (miRNA). DANCR expression was up-regulated in EC tissues as compared to the normal control tissues. Knockdown of DANCR in AN3CA and HEC-1B cells markedly suppressed cell proliferation and induced cell apoptosis. miR-214 was found to be a target miRNA of DANCR and its expression was significantly decreased in EC tissues. Suppression of miR-214 abolished the effects of si-DANCR on cell proliferation and apoptosis in AN3CA and HEC-1B cells. DANCR played an important role in promoting tumorigenesis of EC via sponging miR-214. DANCR might serve as a therapeutic target for the treatment of EC.

Abstract
Previous studies have suggested that microRNAs (miRNAs) are associated with the progression of myocardial ischemic reperfusion (I/R) injury. However, inconsistent results have been obtained due to the differences in sequencing platform, control selection, and filtering conditions. To explore the key miRNAs in the pathogenesis of myocardial I/R injury and develop miRNA diagnostic biomarkers for myocardial I/R injury prevention, we performed a systematic analysis of publicly available myocardial I/R injury miRNA expression data and investigated the function of the signature miRNA. A total of 17 representative myocardial I/R injury miRNA datasets were extracted from the Google Scholar website and a systematic bioinformatics analysis was done. TargetScan software was used to predict the miRNA target genes, and functional enrichment and transcription factor binding analyses were performed on the target genes using the DAVID and Tfacts databases. In this study, a total of 10 signature miRNAs associated with myocardial I/R injury were identified, which included eight significantly upregulated miRNAs (miR-let-7b-3p, miR-let-7c-3p, miR-15b-3p, miR-195-3p, miR-21-5p, miR-214-5p, miR-24-3p, and miR-320a) and two significantly downregulated miRNAs (miR-126-5p and miR-499a-5p). They had different influences on myocardial I/R injury. The upregulated target gene-expressing signature messenger RNAs (mRNAs) were mainly involved in the transcriptional regulation process of GO: 0000122, negative regulation of transcription from RNA polymerase II promoter, and so on, while downregulated expression of signature mRNAs was mainly involved in GO:0070534, protein K63-linked ubiquitination, and so forth. To summarize, 10 signature miRNAs of myocardial I/R injury pathogenesis were identified and their target genes and transcription factors were revealed, suggesting the potential novel therapeutic targets for myocardial I/R injury.

Abstract
BACKGROUND Urothelial bladder cancer (UBC) is one of the most lethal urological malignancies in the world. Patients with UBC are routinely given chemotherapy which results in a median survival of 12-15 months. Nuclear-enriched abundant transcript 1 (NEAT1) functions as an oncogene and could be used as a therapeutic target for human UBC. However, the involvement of NEAT1 in doxorubicin (DOX) resistance of UBC has been poorly demonstrated. METHODS Quantitative Real-time PCR (qRT-PCR) was used to detect the expression levels of NEAT1 and miR-214-3p in UBC tissues and cells. Bioinformatics prediction, RNA pull-down and qRT-PCR were used to assay the regulation manner of NEAT1 and miR-214-3p. Loss/gain function of NEAT1 and miR-214-3p together with western blot, drug resistance assay and flow cytometry were used to explore the influence of NEAT1 in DOX resistance was correlative with miR-214-3p. Finally, luciferase assay system was applied to determine the Wnt/β-catenin signal activity. RESULTS NEAT1 was upregulated and miR-214-3p was downregulated in DOX-resistant UBC tissues and cells. NEAT1 knockdown inhibited J82 and T24 cells to DOX chemosensitivity by negatively regulating miR-214-3p expression. NEAT1/miR-214-3p contributed to DOX resistance of UBC preliminary through the Wnt/β-catenin pathway. CONCLUSION NEAT1 contributed to DOX resistance of UBC through the Wnt/β-catenin pathway partly by negatively regulating miR-214-3p expression. Our findings will provide a promising ncRNA targeted therapeutic strategy for UBC with DOX resistance.

Int J Mol Med 2018; 42:3027-3036. [PMID: 30272290 PMCID: PMC6202080 DOI: 10.3892/ijmm.2018.3902] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2017] [Accepted: 07/25/2018] [Indexed: 12/16/2022] Open
Abstract
MicroRNAs (miRNAs) have important effects on cancer occurrence and development by adjusting gene expression. The aim of the present study was to examine the role of miR-214 in papillary thyroid carcinoma cell proliferation and metastasis, and its molecular mechanisms. miR-214 was demonstrated to be markedly downregulated in papillary thyroid carcinoma tissues and cells compared with normal, and this was significantly associated with lymph node metastasis, tumor size and TNM stage. Upregulation of miR-214 significantly decreased cell proliferation, and promoted cell apoptosis and cell cycle arrest in papillary thyroid carcinoma cell lines in vitro. By contrast, downregulation of miR-214 resulted in the opposite effects. In addition, miR-214 mimics significantly decreased papillary thyroid carcinoma cell migration and invasion, which was correlated with decreased expression levels of matrix metallopeptidase (MMP)-2 and MMP-9. Restoration of miR-214 expression in papillary thyroid carcinoma cells decreased the activities associated with epithelial-mesenchymal transition (EMT). Furthermore, proteasome 26S subunit non-ATPase 10 (PSMD10) was predicted to be a target of miR-214. Experimental results demonstrated that miR-214 negatively regulated PSMD10 expression by targeting its 3′ untranslated region directly. Knockdown of PSMD10 reduced papillary thyroid carcinoma cell clone formation, migration and invasion, most likely by repressing glycogen synthase kinase (GSK)-3β/β-catenin and AKT signaling. Finally, a negative correlation was observed between the expression levels of miR-214 and PSMD10 in papillary thyroid carcinoma tissues. Taken together, these data suggested that miR-214 might be a candidate target for the treatment of papillary thyroid carcinoma.

Abstract
Recent findings have reported that human microRNAs (miRNAs) could serve as prognostic biomarkers in various cancers. We aimed to identify miRNAs that were associated with lymph node metastasis (LNM) and prognosis in breast cancer patients. A miRNA microarray covering 2019 mature miRNAs was used to identify differentially expressed miRNAs in 9 patients with LNM and 3 patients without LNM. Thirty-five differentially expressed miRNAs were identified, of which 10 significantly were up-regulated, whereas the other 25 were down-regulated in tissues with LNM compared with those without LNM. Seven miRNAs were subjected to quantitative real-time polymerase chain PCR (qRT-PCR) reaction, and 4 miRNAs (miR-191-5p, miR-214-3p, miR-451a, and miR-489) were validated in a total of 159 patients including a training set (n = 64) and a validation set (n = 95). The 4 miRNAs were used to construct a miRNA signature by logistic regression. Risk scores derived from the 4-miRNA signature were calculated to stratify the patients into high- or low-risk groups. Patients with high-risk scores had poorer overall survival and disease-free survival than did those with low-risk scores. The miRNA signature was an independent prognostic factor. MiR-191-5p increased, whereas miR-214-3p, miR-451a, and miR-489 inhibited cell proliferation, migration, and invasion abilities. The 4-miRNA signature may be a reliable prognostic and predictive tool for metastasis and survival in breast cancer patients.

Abstract
miR‑214 has been reported to be downregulated in several cancer types, such as bladder cancer. However, its involvement in apoptosis and chemoresistance has not been investigated. The present study aimed to clarify the biological function of miR‑214 and potential mechanisms in chemoresistance of bladder cancer cells. Reverse transcription‑quantitative polymerase chain reaction demonstrated that miR‑214 was downregulated in bladder cancer tissues compared with the level in normal tissues. miR‑214 was downregulated in bladder cancer cell lines compared with the level in the normal cell line SV‑HUC‑1. miR‑214 mimics were transfected into T24 and J82 cell lines to restore its expression. The results indicated that miR‑214 mimic inhibited proliferation and invasion in these cell lines. In addition, miR‑214 mimic reduced cisplatin resistance in T24 and J82 cells, indicated by the inhibition of cell viability and upregulation of cell apoptosis. Western blotting demonstrated that miR‑214 mimic was able to upregulate cleaved caspase‑3 and cleaved poly (ADP‑ribose) polymerase (PARP), while downregulate caspase‑3 and PARP expression, and AKT phosphorylation. Using prediction software, it was revealed that the netrin‑1 oncoprotein is on the target list of miR‑214. miR‑214 also downregulated netrin‑1 protein and mRNA expression levels in the T24 and J82 cell lines. Luciferase reporter assays demonstrated that netrin‑1 acted as a direct target of miR‑214. A negative correlation between netrin‑1 and miR‑214 expression in bladder cancer tissues was also observed. In addition, cisplatin treatment could induce netrin‑1 protein expression in bladder cancer cells and miR‑214 mimic partly blocked this phenomenon. Netrin‑1 plasmid transfection inhibited cisplatin‑induced apoptosis, upregulated AKT phosphorylation, and downregulated caspase‑3 and PARP cleavage. Netrin‑1 was restored in cells transfected with miR‑214 mimic using plasmid transfection. Netrin‑1 transfection restored AKT phosphorylation and blocked caspase/PARP cleavage in the T24 and J82 cell lines. In conclusion, the present study demonstrated that miR‑214 is downregulated in bladder cancer tissues and cell lines. miR‑214 reduces chemoresistance by targeting netrin‑1 in bladder cancer cell lines.

Abstract
Breast cancer is the most commonly diagnosed cancer among females, and chemoresistance constitutes a major clinical obstacle to the treatment of this disease. MicroRNAs (miRNAs) are related to human cancer development, progression and drug resistance. To identify breast cancer chemoresistance-associated miRNAs, miRNA microarray dataset GSE71142, including five chemoresistant breast cancer tissues and five chemosensitive tissues, was downloaded from the Gene Expression Omnibus (GEO) database. Differentially expressed miRNAs (DE-miRNAs) were obtained by t-test and the potential target genes were predicted by miRWalk2.0. Functional and pathway enrichment analysis by WebGestalt was performed for the potential target genes of DE-miRNAs. Protein-protein interaction (PPI) network was established by STRING database and visualized by Cytoscape software. Enriched transcription factors by the target genes were obtained from FunRich. Breast cancer-associated miRNA-gene pairs were identified from miRWalk2.0. A total of 22 DE-miRNAs were screened out, including 10 upregulated miRNAs (e.g., miR-196a-5p) and 12 downregulated miRNAs (e.g., miR-4472) in the chemoresistant breast cancer tissues, compared with chemosensitive tissues. In total 1,278 target genes were screened out, and they were involved in breast cancer-related pathways such as pathways in cancer, signaling pathways regulating pluripotency of stem cells, endocrine resistance, breast cancer, mTOR signaling and Hippo signaling pathway. NOTCH1 and MAPK14 were identified as hub genes in the PPI network. EGR1 and SP1 were the most enriched transcription factors by the target genes. Several breast cancer-associated miRNA-gene pairs including miR-214-TP53 and miR-16-PPM1D were identified. The current bioinformatics study of miRNAs based on microarray may offer a new understanding into the mechanisms of breast cancer chemoresistance, and may identify novel miRNA therapeutic targets.

Abstract
Background Tumor necrosis factor-alpha (TNF-α) can cause diverse T cell dysfunctions in patients with rheumatoid arthritis (RA). It is involved in the regulation of microRNAs (miRNAs) expression in different cell types. We hypothesized that the expression of T cell miRNAs would be affected by TNF-α, and these miRNAs could participate in the immunopathogenesis of RA. Methods Expression profiles of 270 human miRNAs in Jurkat cells, cultured in the presence or absence of TNF-α for 7 days were analyzed by real-time polymerase chain reaction. Potentially aberrantly expressed miRNAs were validated using T cell samples from 35 patients with RA and 15 controls. Transfection studies were conducted to search for gene expression and biological functions regulated by specific miRNAs. Results Initial analysis revealed 12 miRNAs were significantly lower, whereas the expression level of miR-146a was significantly higher in Jurkat cells after being cultured with TNF-α for 7 days. Decreased expression of miR-139-3p, miR-204, miR-760, miR-524-5p, miR-136, miR-548d-3p, miR-214, miR-383, and miR-887 were noted in RA T cells. Expression levels of miR-139-3p, miR-204, miR-214, and miR-760 were correlated with the use of biologic agents. The transfection of miR-214 mimic suppressed TNF-α-mediated apoptosis of Jurkat cells. Increased phosphorylation of extracellular regulating kinase (ERK) and c-Jun N-terminal kinase (JNK) was noted in RA T cells and Jurkat cells after TNF-α exposure. Transfection of Jurkat cells with miR-214 mimic suppressed both the basal and TNF-α-mediated ERK and JNK phosphoryation. Conclusions Among T cell miRNAs affected by TNF-α, the expression levels of nine miRNAs were decreased in T cells from patients with RA. The expression levels of miR-139-3p, miR-204, miR-214, and miR-760 increased in RA patients receiving biologic agents. The transfection of miR-214 reversed the TNF-α-mediated cells apoptosis and inhibited the phosphorylation of ERK and JNK in Jurkat cells.

Cell Biochem Funct 2017; 35:464-471. [PMID: 29023799 DOI: 10.1002/cbf.3304] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2017] [Revised: 08/16/2017] [Accepted: 09/17/2017] [Indexed: 12/19/2022]
Abstract
High Mobility Group AT-hook 1 (HMGA1) was identified as a target of miR-214 in human cervical and colorectal cancers (CaCx and CRC) in a previous study. While the expression of miR-214 remains suppressed, HMGA1 behaves as a potent oncogene and plays crucial roles in several aberrant signalling pathways by interacting with intermediates like RELA, CTNNB1, STAT3, and TP53 in CaCx and CRC. Hypothetically, miR-214 should be able to regulate the stabilization of some of these intermediates through the regulation of HMGA1. This was assessed by ectopically expressing miR-214 or complementarily, by inhibiting the expression of HMGA1. In promoter luciferase assays, miR-214 inhibited NF-κB and Wnt activities but elevated TP53 activity in cancer cells. Further, miR-214 suppressed the expression of HMGA1, RELA, CTNNB1, and STAT3 while elevating TP53 levels, similar to when small interfering RNA (siRNA) against HMGA1 was used, as revealed by Western blotting. It is suggested that poor expression of miR-214, commonly reported in CaCx and CRC tissues, may not only result in the sustained expression of HMGA1 but also that of RELA, CTNNB1, and STAT3, and a congruent suppression of TP53 during cancer initiation/progression. These several states are, however, reversed when miR-214 is reintroduced and could explain the tumour suppressive functions observed in earlier studies. Further studies are, however, required to reveal how microRNA-mediated regulation of HMGA1 expression may affect individual signalling pathways in CaCx and CRC. Current results reveal that miR-214 is not only able to regulate the expression of its direct target, HMGA1, but also that of a few signalling intermediates like TP53, RELA, CTNNB1, and STAT3, with which HMGA1 interacts. These intermediates play crucial roles in signalling pathways commonly deregulated in human CaCx and CRC. Hence, it is proposed that miR-214 might act as a tumour suppressor by regulating several aberrant signalling pathways through HMGA1. This knowledge has the potential to help design novel therapeutic strategies in CaCx and CRC.

Abstract
To improve the clinical decision‐making regarding further treatment management and follow‐up scheduling for patients with muscle‐invasive bladder cancer (MIBC) after radical cystectomy (RC), a better prediction accuracy of prognosis for these patients is urgently needed. The objective of this study was to evaluate the validity of differentially expressed microRNAs (miRNAs) based on a previous study as prognostic markers for overall survival (OS) after RC in models combined with clinicopathological data. The expression of six miRNAs (miR‐100‐5p, miR‐130b‐3p, miR‐141‐3p, miR‐199a‐3p, miR‐205‐5p, and miR‐214‐3p) was measured by RT‐qPCR in formalin‐fixed, paraffin‐embedded tissue samples from 156 MIBC patients who received RC in three urological centers. Samples from 2000 to 2013 were used according to their tissue availability, with follow‐up until June 2016. The patient cohort was randomly divided into a training (n = 100) and test set (n = 56). Seventy‐three samples from adjacent normal tissue were used as controls. Kaplan–Meier, univariate and multivariate Cox regression, and decision curve analyses were carried out to assess the association of clinicopathological variables and miRNAs to OS. Both increased (miR‐130b‐3p and miR‐141‐3p) and reduced (miR‐100‐5p, miR‐199a‐3p, and miR‐214‐3p) miRNA expressions were found in MIBC samples in comparison to nonmalignant tissue samples (P < 0.0001). miR‐199a‐3p and miR‐214‐3p were independent markers of OS in Cox regression models with the significant clinicopathological variables age, tumor status, and lymph node status. The prediction model with the clinicopathological variables was improved by these two miRNAs in both sets. The predictive benefit was confirmed by decision curve analysis. In conclusion, the inclusion of both miRNAs into models based on clinical data for the outcome prediction of MIBC patients after RC could be a valuable approach to improve prognostic accuracy.

Abstract
The transcriptional factor p53 activates the expression of a myriad of target genes involving a complicated signalling network, resulting in various cellular outcomes, such as growth arrest, senescence, apoptosis, and metabolic changes, and leading to consequent suppression of tumour growth and progression. Because of the profoundly adverse effect of p53 on growth and proliferation of cancer cells, several feedback mechanisms have been employed by the cells to constrain p53 activity. Two major antagonists MDM2 and MDMX (the long forms) are transcriptionally induced by p53, but in return block p53 activity, forming a negative feedback circuit and rendering chemoresistance of several cancer cells. However, they are not alone, as cancer cells also employ other proteins encoded by p53 target genes to inhibit p53 activity at transcriptional, translational, and posttranslational levels. This essay is thus composed to review a recent progress in understanding the mechanisms for how cancer cells hijack the p53 autoregulation by these proteins for their growth advantage and to discuss the clinical implications of these autoregulatory loops.

Abstract
Background Increasing evidence highlights the important roles of tripartite motif containing 24 (TRIM24) in tumor initiation and malignant progression in many tumors, including gastric cancer (GC). Although TRIM24 expression is remarkably upregulated during GC carcinogenesis, the molecular mechanisms underlying TRIM24 dysregulation remain unexplored. Methods In this study, miRNA target prediction tools were applied to explore miRNAs that potentially target TRIM24. Western blot and quantitative reverse-transcriptase PCR (qRT-PCR) were performed to detected TRIM24 and miR-511 expression in GC tissues and cell lines. Dual-luciferase reporter assay was utilized to validate if TRIM24 is a direct target gene of miR-511. CCK-8 assay, cell colony formation assay, EdU incorporation assay and cell cycle analysis were performed to determine whether miR-511-mediated regulation of TRIM24 could affect GC progression. Results In our study, miR-511 was found to be downregulated in GC and an inverse correlation was observed between TRIM24 and miR-511 expression in primary GC tissues and cell lines. Dual-luciferase reporter assay further verified TRIM24 is a direct target of miR-511. Functional assays showed miR-511 overexpression inhibited cell growth, colony formation ability and cell cycle progression. Conversely, inhibition of endogenous miR-511 promoted these phenotypes in GC cells. Moreover, reintroduction of TRIM24 rescued miR-511-induced inhibitory effects on GC cells. Furthermore, miR-511 elicits tumor-suppressive effects through inactivating PI3K/AKT and Wnt/β-catenin pathways by suppressing TRIM24. Conclusions Our results provide the new evidence supporting the tumor-suppressive role of miR-511 in GC by suppressing TRIM24, suggesting that this novel miR-511/TRIM24 axis is critical in the control of gastric cancer tumorigenesis.

Biochem Biophys Res Commun 2016; 479:893-900.

Abstract
Epigenetic gene inactivation by microRNAs (miRNAs) plays a key role in malignant transformation, prevention of apoptosis, drug resistance and metastasis. It has been shown that miR-125a is down-regulated in HER2-amplified and HER2-overexpressing breast cancers (BCa), and this miRNA is believed to serve as an important tumor suppressor. miR-125a has two mature forms: hsa-miR-125a-3p and hsa-miR-125a-5p. However, the functional details of these miRNAs in BCa, particularly during pathogenesis of drug resistance, remain largely unexplored. Herein, we reported that hsa-miR-125a-3p expression was significantly reduced in chemoresistant BCa tissues and in experimentally established chemoresistant BCa cells. hsa-miR-125a-3p knockdown promoted cell proliferation and compromised docetaxel (Dox)-induced cell death, whereas overexpression of hsa-miR-125a-3p attenuated Dox chemoresistance in BCa cells. From a mechanistic standpoint, hsa-miR-125a-3p directly targeted 3'-untranslated regions (3'-UTRs) of breast cancer early onset gene 1 (BRCA1) and inhibits its protein expression via translational repression mechanism. In addition, suppression of BRCA1 expression by siRNA treatment effectively improved hsa-miR-125a-3p deficiency-triggered chemoresistance in BCa cells. Collectively, these findings suggest that hsa-miR-125a-3p may function as a tumor suppressor by regulating the BRCA1 signaling, and reintroduction of hsa-miR-125a-3p analogs could be a potential adjunct therapy for advanced/chemoresistant BCa.
