Abstract
Transcription factors, as the convergence points of multiple signaling pathways in eukaryotic cells, are closely involved in disease development. Pax-8, an important transcription factor belonging to the Pax family, exerts a crucial influence on the regulation of gene expression required for both physiological conditions and pathological processes. Pax-8 contributes to the pathogenesis of many human diseases, ranging from cardiovascular disease to many cancers, and therefore, it can be imagined that Pax-8 holds great therapeutic potential. In this review, we summarize the structure, distribution, function, and regulatory mechanisms of Pax-8 to provide a new research direction for Pax-8.

Highly expressed miR-144-3p promotes the proliferation, migration and invasion of colon carcinoma cells by activating the Wnt/β-catenin signaling pathway through targeting SFRP1. J Cancer 2023; 14:3117-3129. [PMID: 37859826 PMCID: PMC10583587 DOI: 10.7150/jca.87792] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Accepted: 09/04/2023] [Indexed: 10/21/2023] Open
Abstract
Background: To investigate the influence of miR-144-3p on the proliferation, migration and invasion of colon carcinoma by targeting secreted frizzled-related protein 1 (SFRP1) as well as of the Wnt/β-catenin signaling pathway. Methods: Based on the TCGA database, the association between the expression of miR-144-3p and the clinical information and prognosis of patients with colon carcinoma was examined, and SFRP1 was selected as the target gene for further studies based on bioinformatics prediction tools. CCK8 assay, wound healing assay and transwell invasion assay were employed to examine the impact of miR-144-3p on colon carcinoma cells. The regulation of SFRP1 by miR-144-3p was investigated using a dual-luciferase reporter system, and a rescue experiment was conducted to further elucidate whether miR-144-3p promotes the migration of colon carcinoma cells through targeting SFRP1 or not. The Wnt/β-catenin signaling pathway-mediated effect of miR-144-3p in colon carcinoma was finally validated through the targeting of SFRP1. Results: The bioinformatics analysis showed that the miR-144 expression levels were substantially greater in colon carcinoma tissue than in para-carcinoma tissue and were closely with clinical stage and prognosis. The findings obtained from the trial indicated that miR-144-3p substantially expressed in colon carcinoma tissue sample and the colon carcinoma cells, and the overexpressed miR-144-3p boosted the colon carcinoma cells' proliferation, migration and invasion. The results of dual-luciferase reporter gene assay revealed that miR-144-3p targeted SFRP1, and rescue experiment was carried out and its results indicated that miR-144-3p increased colon carcinoma cells' migration through targeting SFRP1. In addition, the molecular axis of miR-144-3p/SFRP1 may over-activate the Wnt/β-catenin signaling pathway. Conclusions: The present study has identified a novel malignant biological behavior, namely the ability of miR-144-3p to enhance the proliferation, migration and invasion of colon carcinoma cells by targeting SFRP1 and activating the Wnt/β-catenin signaling pathway. Consequently, miR-144-3p emerges as a promising diagnostic and therapeutic target for colon carcinoma.

Abstract
Cyclin D1 functions as a mitogenic sensor that specifically binds to CDK4/6, thereby integrating external mitogenic inputs and cell cycle progression. Cyclin D1 interacts with transcription factors and regulates various important cellular processes, including differentiation, proliferation, apoptosis, and DNA repair. Therefore, its dysregulation contributes to carcinogenesis. Cyclin D1 is highly expressed in papillary thyroid carcinoma (PTC). However, the particular cellular mechanisms through which abnormal cyclin D1 expression causes PTC are poorly understood. Unveiling the regulatory mechanisms of cyclin D1 and its function in PTC may help determine clinically effective strategies, and open up better opportunities for further research, leading to the development of novel PTC regimens that are clinically effective. This review explores the mechanisms underlying cyclin D1 overexpression in PTC. Furthermore, we discuss the role of cyclin D1 in PTC tumorigenesis via its interactions with other regulatory elements. Finally, recent progress in the development of therapeutic options targeting cyclin D1 in PTC is examined and summarized.

Abstract
Hepatocellular carcinoma (HCC) is a symptomatic disease involed multi-stage program. Here, we elucidated the molecular mechanism of LncTUG1 in the regulation of HCC evolvement. And that may in all likelyhood supply a innovative latent target for HCC's diagnoses and prognosis. LncRNA TUG1, miR-144-3p, RRAGD and mTOR signaling pathway were screened as target genes in the database, and their expression levels at the cytological level were verified utilized qRT-PCR, Western Blot and immunohistochemistry. Then, we adopted CCK-8, Transwell and flow cytometry assays to estimate cell proliferation, invasion and apoptosis. By use of luciferase reporter assay, the relationships of LncRNA TUG1, miR-144-3p and RRAGD was confirmed. In addition, the LncRNA TUG1-miR-144-3p-RRAGD-mTOR signaling pathway in HCC cells was verified adopted rescue experiment and confirmed by xenotransplantation animal experiment. LncTUG1 in HCC tissues from three databases were identified and further verified through qRT-PCR in HCC cells (Huh7, Hep3B). Knockdown the LncTUG1 could increase apoptosis and inhibite invasion and proliferation in HCC cells. Using inhibitors and activators of the mTOR/S6K pathway, LncTUG1 was confirmed to regulate HCC progression by the mTOR/S6K pathway. Luciferase reporter assay demonstrated that TUG1 negatively regulates miR-144-3p. Furthermore, miR-144-3p negativly regulates RRAGD by way of interacting with the 3'UTR of the RRAGD mRNA in HCC utilized luciferase reporter assay. In vivo, we also discovered that neoplasm weight and tumor volume reduced significantly in subcutaneous xenograft nude mouse models derived from sh-LncTUG1-expressing Huh7 cells. And the expressions of p-mTOR, p-S6K and RRAGD were decreased obviously while the miR144-3p increased in subcutaneous xenograft nude mouse models. In a word, the research suggests that LncTUG1 targets miR-144-3p while miR-144-3p binds to RRAGD mRNA, which induces mTOR/S6K pathway activation and promotes the progression of HCC.

MicroRNA expression profiling of RAS-mutant thyroid tumors with follicular architecture: microRNA signatures to discriminate benign from malignant lesions. J Endocrinol Invest 2023:10.1007/s40618-023-02023-5.

Abstract
PURPOSE RAS mutations represent common driver alterations in thyroid cancer. They can be found in benign, low-risk and malignant thyroid tumors with follicular architecture, which are often diagnosed as indeterminate nodules on preoperative cytology. Therefore, the detection of RAS mutations in preoperative setting has a suboptimal predictive value for malignancy. In this study, we investigated differentially expressed microRNA (miRNA) in benign and malignant thyroid tumors with follicular architecture carrying mutations in RAS genes. METHODS Total RNA was purified from 60 RAS-mutant follicular-patterned thyroid tumors, including follicular adenoma (FA), noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP), papillary and follicular thyroid carcinoma cases (PTC, FTC); 22 RAS-negative FAs were used as controls. The expression analysis of 798 miRNAs was performed by digital counting (nCounter nanoString platform). RESULTS Comparing RAS-mutant and RAS-negative FAs, 12 miRNAs showed significant deregulation, which was likely related to the oncogenic effects of RAS mutations. Twenty-two miRNAs were differentially expressed in RAS-mutant benign versus malignant tumors. Considering the tumor type, 24 miRNAs were deregulated in PTC, 19 in NIFTP, and seven in FTC and compared to FA group; among these, miR-146b-5p, miR-144-3p, and miR-451a showed consistent deregulation in all the comparisons with the highest fold change. CONCLUSIONS The miRNA expression analysis of follicular-patterned thyroid tumors demonstrated that RAS mutations influences miRNA profile in benign tumors. In addition, several miRNAs showed a histotype-specific deregulation and could discriminate between RAS-mutant benign and RAS-mutant malignant thyroid lesions, thus deserving further investigation as potential diagnostic markers.

Global microRNA expression profile in laryngeal carcinoma unveils new prognostic biomarkers and novel insights into field cancerization. Sci Rep 2022; 12:17051. [PMID: 36224266 PMCID: PMC9556831 DOI: 10.1038/s41598-022-20338-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Accepted: 09/12/2022] [Indexed: 12/30/2022] Open
Abstract
Laryngeal carcinoma is still a worldwide burden that has shown no significant improvement during the last few decades regarding definitive treatment strategies. The lack of suitable biomarkers for personalized treatment protocols and delineating field cancerization prevents further progress in clinical outcomes. In the light of this perspective, MicroRNAs could be promising biomarkers both in terms of diagnostic and prognostic value. The aim of this prospective study is to find strong prognostic microRNA biomarkers for advanced laryngeal carcinoma and molecular signatures of field cancerization. Sixty patients were enrolled and four samples were collected from each patient: tumor surface and depth, peritumor normal mucosa, and control distant laryngeal mucosa. Initially, a global microRNA profile was conducted in twelve patients from the whole cohort and subsequently, we validated a selected group of 12 microRNAs with RT-qPCR. The follow-up period was 24 months (SD ± 13 months). Microarray expression profile revealed 59 dysregulated microRNAs. The validated expression levels of miR-93-5p (χ2(2) = 4.68, log-rank p = 0.03), miR-144-3p (χ2(2) = 4.53, log-rank p = 0.03) and miR-210-3p (χ2(2) = 4.53, log-rank p = 0.03) in tumor samples exhibited strong association with recurrence-free survival as higher expression levels of these genes predict worse outcome. Tumor suppressor genes miR-144-3p (mean rank 1.58 vs 2.14 vs 2.29, p = 0.000) and miR-145-5p (mean rank 1.57 vs 2.15 vs 2.28, p = 0.000) were significantly dysregulated in peritumor mucosa with a pattern of expression consistent with paired tumor samples thus revealing a signature of field cancerization in laryngeal carcinoma. Additionally, miR-1260b, miR-21-3p, miR-31-3p and miR-31-5p were strongly associated with tumor grade. Our study reports the first global microRNA profile specifically in advanced laryngeal carcinoma that includes survival analysis and investigates the molecular signature of field cancerization. We report two strong biomarkers of field cancerization and three predictors for recurrence in advance stage laryngeal cancer.

Abstract
Considering the significance of LINC01061 in papillary thyroid cancer, here, we commenced to study the role of LINC01061 in autoimmune thyroid disease (AITD) and the potential mechanism. Thyroid tissues were attained from patients with AITD, and Nthy-ori 3-1 cells were induced with lipopolysaccharide (LPS), followed by measurement of LINC01061, microRNA (miR)-612, and BRD4 expression as well as their binding relation. The ectopic expression and silencing experimentations were carried out in LPS-induced Nthy-ori 3-1 cells to detect cell viability and apoptosis as well as inflammation and inflammasome. BRD4 and LINC01061 upregulation and miR-612 downregulation were observed in thyroid tissues of AITD patients and LPS-induced Nthy-ori 3-1 cells. Mechanistic analysis manifested that LINC01061 bound to miR-612 that negatively targeted BRD4. LINC01061 upregulated BRD4 to enhance cell viability, trigger inflammation and inflammasome activation but reduce apoptosis of LPS-induced Nthy-ori 3-1 cells by sponging miR-612. In conclusion, LINC01061 induced the occurrence of AITD by upregulation of miR-612-mediated BRD4 expression.

Abstract
CONTEXT microRNA (miR/miRNA)-144-3p has been implicated in thyroid cancer (TC) progression with poorly identified mechanisms. Furthermore, E2F2 has been documented to assume a role in the development of various cancers. OBJECTIVE This research sought to ascertain the role of miR-144-3p in growth and epithelial-mesenchymal transition (EMT) in TC in cells and male BALB/c nude mice. METHODS In the obtained TC cells, miR-144-3p expression was detected by quantitative reverse transcription polymerase chain reaction, and E2F2 and TNIK expression by Western blot analysis. After gain- and loss-of-function assays, cell viability, clone formation, migration, and invasion were assessed by cell counting kit-8, clone formation, scratch, and Transwell assays. The expression of EMT-related proteins (Snail, Vimentin, N-cadherin, and E-cadherin) was tested by Western blot analysis. The targeting relationship between miR-144-3p and E2F2 was evaluated by dual-luciferase reporter and radioimmunoprecipitation assays, and the binding relationship between E2F2 and TNIK by dual-luciferase reporter and chromatin immunoprecipitation assays. TC cell growth in vivo was determined by subcutaneous tumorigenesis assays in nude mice. RESULTS miR-144-3p was downregulated, whereas E2F2 and TNIK were upregulated in TC cells. Mechanistically, miR-144-3p inversely targeted E2F2, which increased TNIK expression by binding to TNIK promoter in TC cells. Overexpression of miR-144-3p reduced proliferation, migration, invasion, and EMT of FRO and KTC3 cells, which was nullified by overexpressing E2F2 or TNIK expression. Upregulation of miR-144-3p diminished FRO cell growth and EMT in nude mice, which was abrogated by overexpressing TNIK. CONCLUSION miR-144-3p inhibits cell growth and EMT in TC through E2F2/TNIK axis inactivation in cells and male BALB/c nude mice.

Abstract
Thyroid carcinoma is a common malignant tumor of endocrine system and head and neck. Recurrence, metastasis and high malignant expression after routine treatment are serious clinical problems, so it is of great significance to explore its mechanism and find action targets. Epithelial-mesenchymal transition (EMT) is associated with tumor malignancy and invasion. One key change in tumour EMT is low expression of E-cadherin. Therefore, this article reviews the expression of E-cadherin in thyroid cancers (TC), discuss the potential mechanisms involved, and outline opportunities to exploit E-cadherin on regulating the occurrence of EMT as a critical factor in cancer therapeutics.

Abstract
OBJECTIVES Present study aimed to illustrate the role of miR-144-3p in RA. METHODS N1511 chondrocytes were stimulated by IL-1β to mimic RA injury model in vitro. Rats were subjected to injection of type II collagen to establish an in vivo RA model and the arthritis index score was calculated. Cell viability was determined by CCK-8. The expression of cartilage extracellular matrix proteins (Collagen II and Aggrecan) and matrix metalloproteinases protein (MMP-13) were determined by qRT-PCR and western blots. Cell apoptosis was measured by Flow cytometry. ELISA was applied to test the secretion of pro-inflammatory cytokines (IL-1β and TNF-α). Tissue injury and apoptosis were detected by HE staining and TUNEL staining. Interaction of miR-144-3p and BMP2 was verified by dual luciferase assay. RESULTS MiR-144-3p was dramatically increased in IL-1β induced N1511 cells. MiR-144-3p depletion elevated cell viability, suppressed apoptosis, pro-inflammatory cytokine releasing, and extracellular matrix loss in IL-1β induced N1511 cells. Moreover, miR-144-3p targeted BMP2 to modulate its expression negatively. Activation of PI3K/Akt signaling compromised inhibition of BMP2 induced aggravated N1511 cell injury with IL-1β stimulation. Inhibition of miR-144-3p alleviated cartilage injury and inflammatory in RA rats. CONCLUSION Collectively, miR-144-3p could aggravate chondrocytes injury inflammatory response in RA via BMP2/PI3K/Akt axis.

J Transl Med 2021; 19:432. [PMID: 34657624 PMCID: PMC8521984 DOI: 10.1186/s12967-021-03093-w] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Accepted: 09/26/2021] [Indexed: 12/14/2022] Open
Abstract
Background Gastric cancer (GC) is the fifth most commonly diagnosed cancer worldwide. Due to the dismal prognosis, identifying novel therapeutic targets in GC is urgently needed. Evidences have shown that miRNAs played critical roles in the regulation of tumor initiation and progression. GLI family zinc finger 2 (GLI2) has been reported to be up-regulated and facilitate cancer progression in multiple malignancies. In this study, we focused on identifying GLI2-targeted miRNAs and clarifying the underlying mechanism in GC. Methods Paired fresh gastric cancer tissues were collected from gastrectomy patients. GLI2 and miRNAs expression were detected in gastric cancer tissues and cell lines. Bioinformatics analysis was used to predict GLI2-targeted miRNAs and dual-luciferase reporter assay was applied for target verification. CCK-8, clone formation, transwell and flow cytometry were carried out to determine the proliferation, migration, invasion and cell cycle of gastric cancer cells. Tumorsphere formation assay and flow cytometry were performed to detail the stemness of gastric cancer stem cells (GCSCs). Xenograft models in nude mice were established to investigate the role of the miR-144-3p in vivo. Results GLI2 was frequently upregulated in GC and indicated a poor survival. Meanwhile, miR-144-3p was downregulated and negatively correlated with GLI2 in GC. GLI2 was a direct target gene of miR-144-3p. MiR-144-3p overexpression inhibited proliferation, migration and invasion of gastric cancer cells. Enhanced miR-144-3p expression inhibited tumorsphere formation and CD44 expression of GCSCs. Restoration of GLI2 expression partly reversed the suppressive effect of miR-144-3p. Xenograft assay showed that miR-144-3p could inhibit the tumorigenesis of GC in vivo. Conclusions MiR-144-3p was downregulated and served as an essential tumor suppressor in GC. Mechanistically, miR-144-3p inhibited gastric cancer progression and stemness by, at least in part, regulating GLI2 expression.

Abstract
Thyroid cancer is the most common tumor arising from the endocrine system and generally presents good prognosis. However, its aggressive subtypes are related to therapeutic resistance and early metastasis. Epithelial–mesenchymal transition (EMT) and its reverse process, the mesenchymal–epithelial transition (MET), are key events mediating cancer progression, including in thyroid cancer. The matricellular protein osteopontin (OPN) has been reported as a master regulator of EMT in many tumor types. Although high OPN expression has been described and associated with important aspects of thyroid cancer progression, there is no clear evidence regarding OPN as a regulator of EMT in thyroid cancer. Thus, taking together the known roles of OPN in the modulation of EMT in cancer and the information reporting the expression of OPN in thyroid tumor progression, this review aims at summarizing and discussing data related to EMT in thyroid cancer and its putative relation to the roles of OPN in the development of thyroid cancer. These data provide new insights into the molecular mechanisms by which OPN could potentially modulate EMT in thyroid tumors, generating evidence for future studies that may contribute to new therapeutic, prognostic and/or diagnostic tools.

Abstract
Glioma remains to be an aggressive type of cancer with poor prognosis irrespective of the type of standard treatment applied. Therefore, identification of accurate early diagnostic methods and therapeutic strategies for glioma is imperative for the treatment of this disease. The expression of a number of miRNAs in glioma have been reported to be associated with the regulation of tumorigenic progression, cancer cell proliferation, metastasis, invasion, angiogenesis and drug resistance. The aim of the present study was to assess the function of the microRNA (miR/miRNA)-144-3p/BCL6 axis in glioma. Reverse transcription-quantitative PCR was used to measure miR-144-3p and BCL6 expression. Western blotting was used for measuring BCL6 expression. Luciferase reporter assay was used to assess the association between miR-144-3p and BCL6 and a tumor xenograft model was established for assess tumor growth. The data demonstrated that miR-144-3p was decreased whereas BCL6 expression was increased in glioma tissues compared with those in healthy human brain tissues, where miR-144-3p suppressed BCL6 expression by targeting the 3'-UTR sequence of BCL6. miR-144-3p overexpression alleviated proliferation and invasion in U251 cells whereas transfection with the BCL6-overexpressing plasmid rescued the suppressive effects of miR-144-3p upregulation on the proliferation and invasion of U251 cells. In addition, miR-144-3p overexpression and BCL6 downregulation inhibited tumor progression in a mouse tumor xenograft model. The present findings suggest that miR-144-3p and BCL6 may serve to be indicator of proliferation and invasion for patients with glioma. Furthermore, BCL6 may serve an important role in the miR-144-3p-mediated regulation of proliferation and invasion of glioma cells, where the miR-144-3p/BCL6 axis can be used to target patients with glioma therapeutically.

Abstract
PURPOSE Long non-coding RNA (lncRNA) is identified as an important regulator involved in oral squamous cell carcinoma (OSCC) tumorigenesis. This study aimed to investigate the functional role and underlying mechanism of LINC00662 in OSCC. MATERIALS AND METHODS The expression levels of LINC00662, miR-144-3p, and enhancer of zeste homolog 2 (EZH2) mRNA were quantified with quantitative real-time polymerase chain reaction in OSCC tissues and cell lines. Western blot analysis was used to assay the expression levels of E-cadherin, Vimentin, and EZH2. Cell proliferation, migration, and invasion were monitored by cell counting kit-8 and Transwell assays. Dual-luciferase reporter and RNA immunoprecipitation assays were employed to verify the regulatory relationship between LINC00662 and miR-144-3p. RESULTS The expression of LINC00662, positively associated with the increased TNM stage and lymph node metastasis of the patients, was up-regulated in OSCC tissues and cells. The overexpression of LINC00662 facilitated the proliferation, migration, and invasion of OSCC cells. MiR-144-3p could bind to LINC00662, and the promoting effect of LINC00662 overexpression was counteracted by miR-144-3p mimic. Moreover, EZH2 expression was negatively regulated by miR-144-3p and positively regulated by LINC00662. The silencing of EZH2 attenuated the promoting effects of overexpression of LINC00662 on cell proliferation, migration, invasion, and epithelial-mesenchymal transition. CONCLUSION LINC00662, as an oncogenic lncRNA of OSCC, accelerates OSCC progression by repressing miR-144-3p expression and increasing EZH2 expression.

Abstract
In oncogenesis and development of malignant tumor, microRNAs (miRNAs) regulate the complex gene expression associated with the tumor pathogenesis. Currently, only few studies have been conducted to identify miRNAs and the potential pathways involved in the pathogenesis of brain metastasis in patients who underwent radiotherapy, especially miRNAs in the plasma exosomes. Therefore, this study is aimed to use small RNA analysis to identify miRNAs and their potential target genes in plasma exosomes during the initiation and development of brain metastasis in patients who underwent radiotherapy. Using high-throughput sequencing technologies, we identified 35 differentially expressed miRNAs in patients with brain metastasis who had undergone radiotherapy. In annotation of miRNA targets, gene ontology enrichment analysis revealed that the targets of the differentially expressed miRNAs were significantly enriched in the regulation of cellular processes. Kyoto Encyclopedia of Genes and Genomes revealed that most of the miRNA targets were cancer-related, including genes involved in the mitogen-activated protein kinase signaling pathway, cancer-related pathways, phosphatidylinositol 3-kinase-protein kinase B signaling pathway, microtubule-associated protein kinase signaling pathway, Ras signaling pathway, regulation of the actin cytoskeleton, and axon guidance. In conclusion, this study provides a new perspective to understand the possible function of these miRNAs in the pathogenesis of brain metastasis. This was the first time that a pilot study identified plasma exosomal miRNAs in five patients with brain metastasis before and after radiotherapy. This study is the beginning; more specimen and further research are needed to explore the functional role of specific miRNAs and their potential as therapeutic targets for brain metastasis.

Abstract
Thyroid cancer is not among the top cancers in terms of diagnosis or mortality but it still ranks fifth among the cancers diagnosed in women. Infact, women are more likely to be diagnosed with thyroid cancer than the males. The burden of thyroid cancer has dramatically increased in last two decades in China and, in the United States, it is the most diagnosed cancer in young adults under the age of twenty-nine. All these factors make it worthwhile to fully understand the pathogenesis of thyroid cancer. Towards this end, microRNAs (miRNAs) have constantly emerged as the non-coding RNAs of interest in various thyroid cancer subtypes on which there have been numerous investigations over the last decade and half. This comprehensive review takes a look at the current knowledge on the topic with cataloging of miRNAs known so far, particularly related to their utility as epigenetic signatures of thyroid cancer progression and metastasis. Such information could be of immense use for the eventual development of miRNAs as therapeutic targets or even therapeutic agents for thyroid cancer therapy.

Abstract
OBJECTIVES The aim of the present study was to investigate the expression of AXL and mTOR genes and their targeting microRNAs (miRNAs) including miR-34a and miR-144 in Medullary Thyroid Carcinoma (MTC) cell line, TT, and determine the effect of these two miRNAs on their target genes to introduce new molecular markers or therapeutics. METHODS The expression of miR-34a, miR-144, and their targets genes including AXL and mTOR was evaluated by quantitative Real-time PCR. Luciferase assay was performed to confirm the interaction between miRNAs and their target mRNAs. The expression level of AXL and mTOR was evaluated before and after miRNAs induction in TT cell line compared with Cos7 as control cells. RESULTS The expression of AXL and mTOR were up-regulated significantly, while miR-34a and miR-144 were down-regulated in TT cell line compared to Cos7. After transduction, the overexpression of miR-34a and 144 caused down-regulation of both genes. Luciferase assay results showed that the mTOR is targeted by miR-34a and miR-144 and the intensity of luciferase decreased in the presence of miRNAs. CONCLUSIONS Based on the results of the present study and since AXL and mTOR genes play a critical role in variety of human cancers, suppression of these genes by their targeting miRNAs, especially miR-34a and miR-144, can be propose as a new strategy for MTC management. However, more studies are needed to approve the hypothesis.

Abstract
Background: Prostate cancer is a common malignant tumor with a high incidence. MicroRNAs (miRNAs) have been shown to be important post-transcriptional regulators during tumorigenesis. This study aimed to explore the effect of miR-144 on PCa proliferation and apoptosis. Material and Methods: The expression of miR-144 and EZH2 were examined in clinical PCa tissues. PCa cell line LNCAP and DU-145 was employed and transfected with miR-144 mimics or inhibitors. The correlation between miR-144 and EZH2 was verified by luciferase reporter assay. Cell viability, apoptosis and migratory capacity were detected by CCK-8, flow cytometry assay and wound healing assay. The protein level of EZH2, E-Cadherin, N-Cadherin and vimentin were analyzed by western blotting. Results: miR-144 was found to be negatively correlated to the expression of EZH2 in PCa tissues. Further studies identified EZH2 as a direct target of miR-144. Moreover, overexpression of miR-144 downregulated expression of EZH2, reduced cell viability and promoted cell apoptosis, while knockdown of miR-144 led to an inverse result. miR-144 also suppressed epithelial-mesenchymal transition level of PCa cells. Conclusion: Our study indicated that miR-144 negatively regulate the expression of EZH2 in clinical specimens and in vitro. miR-144 can inhibit cell proliferation and induce cell apoptosis in PCa cells. Therefore, miR-144 has the potential to be used as a biomarker for predicting the progression of PCa.

Abstract
Recurrence is a major problem for prostate cancer patients, thus, identifying prognosis-related markers to evaluate clinical outcomes is essential. Here, we established a fifteen-miRNA-based recurrence-free survival (RFS) predicting signature based on the miRNA expression profile extracted from The Cancer Genome Atlas (TCGA) database by the LASSO Cox regression analysis. The median risk score generated by the signature in both the TCGA training and the external Memorial Sloan-Kettering Cancer Center (MSKCC) validation cohorts was employed and the patients were subclassified into low- and high-risk subgroups. The Kaplan-Meier plot and log-rank analyses showed significant survival differences between low- and high-risk subgroups of patients (TCGA, log-rank P < 0.001 & MSKCC, log-rank P = 0.045). In addition, the receiver operating characteristic curves of both the training and external validation cohorts indicated the good performance of our model. After predicting the downstream genes of these miRNAs, the miRNA-mRNA network was visualized by Cytoscape software. In addition, pathway analyses found that the differences between two groups were mainly enriched on tumor progression and drug resistance-related pathways. Multivariate analyses revealed that the miRNA signature is an independent indicator of RFS prognosis for prostate cancer patients with or without clinicopathological features. In summary, our novel fifteen-miRNA-based prediction signature is a reliable method to evaluate the prognosis of prostate cancer patients.

Abstract
Purpose To explore the expression and related mechanism of miR-144-3p and PTEN in thyroid cancer (TC). Patients and Methods From February 2018 to November 2019, 62 patients with TC who received treatment in Chengwu Hospital Affiliated to Shandong First Medical University were collected. TC cells and human normal thyroid HTori-3 cells were purchased. The miR-144-3p-inhibitor, miR-144-3p-mimics, empty vector plasmid (miRNA-NC), si-PTEN and sh-PTEN were transfected into B-CPAP and HTh-7 cells. The expressions of miR-144-3p and PTEN in the specimens were tested by qRT-PCR (qP). WB was used to detect the expression of Bcl-2, APR3, N-cadherin, Slug and Bax proteins in the cells. The cell proliferation was detected by MTT, and the cell invasion was tested by Transwell. The apoptosis was detected by flow cytometry (FC). Results miR-144-3p was highly expressed and PTEN was weakly expressed in the patients’ tissues. The AUC of miR-144-3p and PTEN was >0.8. miR-144-3p and PTEN were related to TNM stage, lymph node metastasis and differentiation degree of TC patients. The B-CPAP and HTh-7 with the greatest expression differences were selected for transfection. The expression of miR-144-3p in miR-144-3p-inhibitor group was significantly lower than that in NC group (P<0.01), and that in miR-144-3p-mimics group was significantly higher than that in NC group (p < 0.01). The expression of PTEN in si-PTEN group was significantly lower than that in NC group (P<0.01), while that in sh-PTEN group was significantly higher than that in NC group (P<0.01). Silencing miR-144-3p and overexpressing PTEN could inhibit cell proliferation, invasion and promote apoptosis. WB detection uncovered that silencing the miR-144-3p expression and overexpressing PTEN could inhibit the PI3K, Akt, p-AKT, Bcl-2, APR3 and cyclinD1 proteins and promote the up-regulation of Bax expression. Rescue experiments revealed that the cell proliferation, invasion and apoptosis were not different from NC after co-transfection of miR-144-3p-mimics+sh-PTEN and miR-144-3p-inhibitor+si-PTEN into B-CPAP and HTh-7. Conclusion Inhibition of miR-144-3p expression can up-regulate PTEN and affect cell proliferation, invasion and apoptosis, which may be a potential therapeutic target for TC.

Abstract
Background: Dysregulation of microRNAs (miRNAs) in papillary thyroid cancer (PTC) might influence prognosis of PTC. This study is aimed to develop a risk score system for predicting prognosis of PTC. Methods: The miRNA and gene expression profiles of PTC were obtained from The Cancer Genome Atlas database. PTC samples were randomly separated into training set (n = 248) and validation set (n = 248). The differentially expressed miRNAs (DE-miRNAs) in the training set were screened using limma package. The independent prognosis-associated DE-miRNAs were identified for building a risk score system. Risk score of PTC samples in the training set was calculated and samples were divided into high risk group and low risk group. Kaplan-Meier curves and receiver operating characteristic (ROC) curve were used to assess the accuracy of the risk score system in the training set, validation set and entire set. Finally, a miRNA-gene regulatory network was visualized by Cytoscape software, followed by enrichment analysis. Results: Totally, 162 DE-miRNAs between tumor and control groups in the training set were identified. An 8 independent prognosis-associated DE-miRNAs, (including miR-1179, miR-133b, miR-3194, miR-3912, miR-548j, miR-6720, miR-6734, and miR-6843) based risk score system was developed. The area under ROC curve in the training set, validation set and entire set was all above 0.93. A miRNA-gene regulatory network involving the 8 DE-miRNAs were built and functional enrichment analysis suggested the genes in the network were significantly enriched into 13 pathways, including calcium signaling pathway and hedgehog signaling pathway. Conclusion: The risk score system developed this study might be used for predicting the prognosis of PTC. Besides, the 8 miRNAs might affect the prognosis of PTC via hedgehog signaling pathway and calcium signaling pathway.

Abstract
MicroRNAs (miRNAs) are a class of small non-coding RNAs that negatively regulate gene expression at the post-transcriptional level. It has been reported that microRNA-144 (miR-144) is highly conserved and can combine complementarily with the 3'-UTRs of target gene mRNAs to inhibit mRNA translation or promote targeted mRNA degradation. MiR-144 is abnormally expressed and has been identified as a tumor suppressor in many types of solid tumors. Increasing evidence supports a crucial role for miR-144 in modulating physiopathologic processes, such as proliferation, apoptosis, invasion, migration and angiogenesis in different tumor cells. Apart from these functions, miR-144 can also affect drug sensitivity, cancer treatment and patient prognosis. In this review, we summarize the biological functions of miR-144, its direct targets and the important signal pathways through which it acts in relation to various tumors. We also discuss the role of miR-144 in tumor biology and its clinical significance in detail and offer novel insights into molecular targeting therapy for human cancers.

Abstract
Pancreatic cancer cells are characterized by high cell proliferation and low cell apoptosis, but the factors involved in these processes remain to be further studied. In this study, we report that miR-324-5p regulates the proliferation and apoptosis of pancreatic cancer cells through regulating the expression of Krüppel-like factor 3 (KLF3). In both pancreatic cancer tissues and cell lines, the levels of miR-324-5p are significantly increased. Inhibition of miR-324-5p represses cell proliferation but promotes cell apoptosis, whereas overexpression of miR-324-5p exerts the opposite effect. Furthermore, we identified KLF3, a factor regulating pancreatic cancer cell proliferation and apoptosis, as a new direct downstream target of miR-324-5p. Our results suggest that miR-324-5p plays an important role in pancreatic cancer cell proliferation and apoptosis via downregulating the expression of KLF3.

Downregulation of miR‑193a‑3p via targeting cyclin D1 in thyroid cancer. Mol Med Rep 2020; 22:2199-2218.

Abstract
Thyroid cancer (TC) is a frequently occurring malignant tumor with a rising steadily incidence. microRNA (miRNA/miR)‑193a‑3p is an miRNA that is associated with tumors, playing a crucial role in the genesis and progression of various cancers. However, the expression levels of miR‑193a‑3p and its molecular mechanisms in TC remain to be elucidated. The present study aimed to probe the expression of miR‑193a‑3p and its clinical significance in TC, including its underlying molecular mechanisms. Microarray and RNA sequencing data gathered from three major databases, specifically Gene Expression Omnibus (GEO), ArrayExpress and The Cancer Genome Atlas (TCGA) databases, and the relevant data from the literature were used to examine miR‑193a‑3p expression. Meta‑analysis was also conducted to evaluate the association between clinicopathological parameters and miR‑193a‑3p in 510 TC and 59 normal samples from the TCGA database. miRWalk 3.0, and the TCGA and GEO databases were used to predict the candidate target genes of miR‑193a‑3p. Gene Ontology, Kyoto Encyclopedia of Genes and Genomes and protein‑protein interaction network enrichment analyses were conducted by using the predicted candidate target genes to investigate the underlying carcinogenic mechanisms. A dual luciferase assay was performed to validate the targeting regulatory association between the most important hub gene cyclin D1 (CCND1) and miR‑193a‑3p. miR‑193a‑3p expression was considerably downregulated in TC compared with in the non‑cancer controls (P<0.001). The area under the curve of the summary receiver operating characteristic was 0.80. Downregulation of miR‑193a‑3p was also significantly associated with age, sex and metastasis (P=0.020, 0.044 and 0.048, respectively). Bioinformatics analysis indicated that a low miR‑193a‑3p expression may augment CCND1 expression to affect the biological processes of TC. In addition, CCND1, as a straightforward target, was validated through a dual luciferase assay. miR‑193a‑3p and CCND1 may serve as prognostic biomarkers of TC. Finally, miR‑193a‑3p may possess a crucial role in the genesis and progression of TC by altering the CCND1 expression.

Abstract
The present study aims to evaluate whether plasma miR-323 serves as a potential biomarker to screen patients with papillary thyroid cancer (PTC) from healthy controls. Real-time PCR was performed to evaluate miR-323 expression in healthy controls and benign thyroid nodule (BTN) and PTC patients. Receiver operating characteristic (ROC) curve analysis was used to evaluate whether plasma miR-323 could be used to screen PTC patients from BTN patients and healthy controls. Plasma miR-323 was significantly increased in PTC patients compared with that in BNT patients and healthy controls. Moreover, miR-323 in the thyroid tissue was significantly increased in PTC patients when compared to BNT patients. We further showed that plasma and tissue miR-323 levels were significantly increased in PTC patients with metastasis compared to those without metastasis. Plasma miR-323 was significantly increased in PTC patients with BRAF V600E mutation when compared to those with wild-type BRAF. Furthermore, plasma miR-323 was significantly increased in PTC patients with higher Tg-FNAB. ROC analysis showed that plasma miR-323 could distinguish PTC patients from BNT patients and healthy controls. The present study demonstrated that plasma miR-323 might be an effective noninvasive indicator for PTC progression and serve as a biomarker for the diagnosis of PTC.

Abstract
Non-coding RNA has been reported to be crucial regulator for cancer progression. This work was aimed to investigate the roles and associated mechanisms of non-coding RNA activated by DNA damage (NORAD) in hepatocellular carcinoma (HCC) progression. In this work, we explored the expression of NORAD, microRNA-144-3p (miR-144-3p), and septin 2 (SEPT2) in HCC tissues and cells. Effects of knockdown of ectopic of NORAD on HCC cell proliferation, colony formation, and apoptosis were explored. Rescue experiments were conducted to explore whether NORAD regulates HCC cell behaviors via the miR-144-3p/SEPT2 axis. Moreover, the effect of NORAD on HCC tumor progression in vivo was analyzed. We showed NORAD expression was elevated in both HCC tissues and cells. NORAD knockdown inhibits HCC cell growth but promotes apoptosis, while the overexpression of NORAD has opposite effects. Besides that, we found knockdown of NPRAD inhibits tumor growth. Moreover, we showed miR-144-3p expression was inversely correlated with NORAD and SEPT2, while NORAD and SEPT2 was positively correlated in HCC tissues. Functional assays showed NORAD functions as ceRNA through binding with miR-144-3p to regulate SEPT2 expression in HCC. Collectively, we showed NORAD serves as an oncogenic lncRNA to promote HCC progression via the miR-144-3p/SEPT2 axis.

Abstract
MicroRNAs (miRNAs) are small and non-coding RNAs that display aberrant expression in the tissue and plasma of cancer patients when tested in comparison to healthy individuals. In past decades, research data proposed that miRNAs could be diagnostic and prognostic biomarkers in cancer patients. It has been confirmed that miRNAs can act either as oncogenes by silencing tumor inhibitors or as tumor suppressors by targeting oncoproteins. MiR-144s are located in the chromosomal region 17q11.2, which is subject to significant damage in many types of cancers. In this review, we assess the involvement of miR-144s in several cancer types by illustrating the possible target genes that are related to each cancer, and we also briefly describe the clinical applications of miR-144s as a diagnostic and prognostic tool in cancers.

Upregulation of Long Noncoding RNA (lncRNA) X-Inactive Specific Transcript (XIST) is Associated with Cisplatin Resistance in Non-Small Cell Lung Cancer (NSCLC) by Downregulating MicroRNA-144-3p. Med Sci Monit 2019; 25:8095-8104.

Abstract
BACKGROUND Patients with advanced non-small cell lung cancer (NSCLC) treated with cisplatin, also termed cis-diamminedichloroplatinum (CDDP) or diamminedichloroplatinum (DDP), may develop chemoresistance. This study aimed to investigate the role of long non-coding RNA (lncRNA) X-inactive specific transcript (XIST) and multidrug resistance-1 (MDR1) in tumor tissue samples and the chemoresistant human NSCLC cell lines, H460/DDP and A549/DDP, and in a murine A549/DDP tumor xenograft. MATERIAL AND METHODS Tissue samples were from patients with NSCLC who responded cisplatin (DDP-sensitive) (n=24), patients with NSCLC unresponsive to cisplatin (DDP-resistant) (n=30), and normal lung tissue (n=25). In H460/DDP and A549/DDP cells, expression of XIST, microRNA (miR)-144-3p, MDR1, and multidrug resistance-associated protein 1 (MRP1) were detected by quantitative reverse transcription polymerase chain reaction (RT-qPCR) and Western blot. The MTT assay measured cell survival and proliferation, a transwell assay evaluated cell migration, and flow cytometry measured apoptosis. Luciferase reporter, RNA immunoprecipitation (RIP), and RNA pull-down assays examined the relationship between XIST and miR-144-3p. Tumor xenografts from A549/DDP cells were studied in BALB/c nude mice. RESULTS In tissue from patients with DDP-resistant NSCLC and the mouse A549/DDP tumor xenograft, lncRNA-XIST expression was upregulated and miR-144-3p expression was inhibited. In A549/DDP and H460/DDP cells, down-regulation of lncRNA-XIST and upregulation of miR-144-3p reduced cell survival, proliferation, migration, induced apoptosis and suppressed MDR1 and MRP1 expression. CONCLUSIONS Upregulation of lncRNA-XIST was associated with cisplatin resistance in NSCLC by downregulating miRNA-144-3p in H460/DDP and A549/DDP cells, a murine A549/DDP tumor xenograft, and human tumor tissues from patients with cisplatin-resistant NSCLC.

Long noncoding RNA MALAT1 promotes cardiomyocyte apoptosis after myocardial infarction via targeting miR-144-3p. Biosci Rep 2019; 39:BSR20191103. [PMID: 31227612 PMCID: PMC6680374 DOI: 10.1042/bsr20191103] [Citation(s) in RCA: 34] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2019] [Revised: 06/11/2019] [Accepted: 06/16/2019] [Indexed: 01/01/2023] Open
Abstract
Our study aims to excavate the role of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in myocardial infarction (MI), especially in an ischemia/reperfusion injury model and the underlying mechanism involving the MALAT1-miR144 axis. Our results demonstrated that the expression of MALAT1 has a higher level, while miR-144 expression significantly reduced in myocardial tissue after MI and also in left anterior descending (LAD)-ligation mice. This result was confirmed in vitro studies in HL-1 cardiomyocytes followed with hypoxia/reoxygenation. In addition, overexpression of MALAT1 by MALAT1-pcDNA injection into the mice with LAD increased myocardial apoptosis in vivo, while this effect was attenuated by miR-144 mimic. Bioinformatics analysis exhibits that 3′-UTR of MALAT1 is targeted to the miR-144-3p. Up-regulation miR-144 blunted the hypoxia- or MALAT1-induced cell apoptosis. In conclusion, the expression of MALAT1 was increased, whereas miR-144 expression was down-regulated in the myocardium after AMI. MALAT1 up-regulation plays a critical role in promoting cardiomyocytes apoptosis via targeting miR-144.

Abstract
Background Chemotherapy based on paclitaxel (PTX) is the standard treatment for a range of cancers, including triple-negative breast cancer (TNBC), but the increasing development of resistance has reduced/has negatively impacted its clinical utility. A previous study demonstrated that miR-5195-3p could suppress lung cancer cell growth. This study was designed to investigate whether miR-5195-3p attenuates chemoresistance to PTX by regulating target genes in TNBC cells. Methods The study used both PTX-resistant tumor tissues and PTX-resistant TNBC cell lines. The expression of miR-5195-3p was determined using quantitative real-time PCR. Cell viability, cell cycle distribution and apoptosis were analyzed using CCK-8 and flow cytometry assays. The target genes of miR-5195-3p were predicted with bioinformatics analysis and confirmed using the luciferase reporter assay. Results MiR-5195-3p expression was lower in PTX-resistant tumor tissues and PTX-resistant TNBC cell lines. Upregulation of miR-5195-3p enhanced the sensitivity of PTX-resistant TNBC cells to PTX treatment. EIF4A2 was confirmed as a potential target of miR-5195-3p. EIF4A2 knockdown imitated the effects of miR-5195-3p on chemosensitivity, while restoration of EIF4A2 rescued them. Conclusion These data demonstrate that miR-5195-3p might be a potential therapeutic target to reverse chemoresistance in TNBC through its targeting of EIF4A2.

miRNA-21 promotes cell proliferation and invasion via VHL/PI3K/AKT in papillary thyroid carcinoma. Hum Cell 2019; 32:428-436.

Abstract
Papillary thyroid carcinoma (PTC) is the main kind of thyroid carcinoma, most of which are diagnosed in women. MiR-21 has been reported to be upregulated in multiple cancers to effect tumor growth. However, the role of miR-21 in PTC development remains unclear. In this present study, miR-21 and VHL expressions in PTC tissues and cells were evaluated by RT-qPCR and/or western blot. MTT assay and transwell assay were employed to assess cell proliferative and invasive abilities, respectively. Luciferase reporter assay was carried out to identify the target of miR-21and explore its roles in PTC. MiR-21 was upregulated in PTC tissues and cells. Ectopic of miR-21 expression promoted cell proliferative and invasive abilities, while knockdown miR-21 suppressed these in TPC-1 and BCPAP cells. Overexpression of miR-21 predicted poor prognosis in PTC. What is more, luciferase reporter assays showed miR-21 can directly target VHL in PTC cells. Knockdown of miR-21 expression inhibited TPC-1 and BCPAP cell invasion-mediated EMT and proliferation through the PI3K/AKT pathway. In addition, VHL reverses partial function of miR-21 on PTC cell proliferation and invasion. MiR-21 can inhibit cell proliferation and invasion by regulated VHL in PTC cells. The newly identified miR-21/VHL axis might provide a novel insight into the pathogenesis and therapy of PTC.

Abstract
Cervical cancer is the third most common gynecologic cancer in the world. Exploration of the molecular mechanism underlying cervical cancer pathogenesis will provide new insights into the development of novel therapies. In this study, we were aimed to characterize a novel miRNA in cervical cancer tumorigenesis. First, we measured the expressional change of miR-144-3p in clinical tissues and cancer cells. Second, we employed cell proliferation, cell migration, and invasion assays to understand its functional role in cervical cancer. Then, we confirmed in vitro findings in xenograft cancer model. Last, we mapped out a downstream target of miR-144-3p and validated its functional role in cancer cells. In the results, miR-144-3p was found significantly downregulated in cervical cancer cells and tissues. Over-expressing miR-144-3p suppressed cancer cells growth and metastasis. Consistent with in vitro results, over-expressing miR-144-3p led to tumor growth inhibition in vivo. Further on, MAPK6 was identified as an endogenous target of miR-144-3p in cervical cancer. Knocking down MAPK6 inhibited cervical cancer cells proliferation, migration, and invasion potential. Our investigation was the first time to report miR-144-3p as a tumor suppressive miRNA in cervical cancer. It inhibited tumor growth by targeting MAKP6. The newly identified signalling axis may serve as novel therapeutic targets to manage cervical cancer.

Abstract
Aim The aim of this study was to detect the effects and potential mechanisms of microRNA-221 on a series of biological behaviors of papillary thyroid carcinoma (PTC) cells in vitro and in vivo. Methods First, we analyzed the relationship between the expression of miR-221 and several clinicopathological features of PTC patients and then detected the expression of the miR-221 in tumor tissues and cell lines. The effects of miR-221 on proliferation and invasion of PTC cells were verified by cell counting kit-8 (CCK-8) assay, wound healing assay and transwell assay. Western blot assay was applied to explore the correlation between miR-221 and RECK expression in PTC K1 cells. Finally, a xenograft model was established to further confirm the tumor-promoting effects of miR-221 in vivo. Results Our data indicated that miR-221 was relatively upregulated in metastatic PTC tissues. MiR-221 promoted the proliferation, migration and invasion activities of PTC K1 cells, following variations of epithelial-mesenchymal transition (EMT)-related protein expression. We identified RECK as a direct target of miR-221, revealed its expression to be inversely correlated with miR-221 in PTC samples and showed that its reintroduction reverses miR-221-induced PTC invasiveness. In addition, miR-221 was also verified to promote tumor growth and increase tumor volume and weight in vivo. Taken together, miR-221/RECK axis could be an effective way to regulate biological behaviors of PTC. Conclusion MiR-221 may be involved in PTC cell invasion and metastasis by targeting RECK, indicating that the miR-221/RECK pathway could be studied further as a potential new diagnostic or prognostic biomarker for PTC.

Abstract
Papillary thyroid carcinoma is one of the most fatal malignant endocrine tumors, and the prognosis remains poor because of the lack of effective therapeutic targets. In this study, we demonstrated that the level of miR-199b-5p was markedly downregulated in papillary thyroid carcinoma. The ectopic expression level of miR-199b-5p in papillary thyroid carcinoma cell B-CPAP could inhibit growth, migration, and invasion as well as epithelial-mesenchymal transition (EMT) and decreased cell metastasis in vivo, but silencing miR-199b-5p caused a contradictory outcome. Additionally, Stonin 2 (STON2) was identified as a direct target gene of miR-199b-5p. Consistent with the downregulation of miR-199b-5p, the overexpression of STON2 induced the growth, migration and invasion of B-CPAP cells. It was also demonstrated that miR-199b-5p suppressed papillary thyroid carcinoma cell aggressiveness by targeting STON2. Furthermore, the overexpression of miR-199b-5p inhibited cell proliferation, promoted apoptosis, and increased the chemo-sensitivity of thyroid carcinoma B-CPAP cells toward the chemotherapy drug paclitaxel. Finally, in vivo experiments further demonstrated that miR-199b-5p suppressed tumor growth in nude mice. Thus, this study revealed that miR-199b-5p functions as antioncogene miRNA in papillary thyroid carcinoma cells and that the miR-199b-5p/STON2 axis might be a potential treatment option for papillary thyroid carcinoma. © 2018 IUBMB Life, 71(1):28-40, 2019.

eNOS expression and NO release during hypoxia is inhibited by miR-200b in human endothelial cells. Angiogenesis 2018; 21:711-724.

Abstract
The nitric oxide (NO) secreted by vascular endothelium is required for the maintenance of cardiovascular homeostasis. Diminished release of NO generated by endothelial NO synthase contributes to endothelial dysfunction. Hypoxia and ischemia reduce endothelial eNOS expression via posttranscriptional mechanisms that result in NOS3 transcript destabilization. Here, we examine whether microRNAs contribute to this mechanism. We followed the kinetics of hypoxia-induced changes in NOS3 mRNA and eNOS protein levels in primary human umbilical vein endothelial cells (HUVECs). Utilizing in silico predictive protocols to identify potential miRNAs that regulate eNOS expression, we identified miR-200b as a candidate. We established the functional miR-200b target sequence within the NOS3 3′UTR, and demonstrated that manipulation of the miRNA levels during hypoxia using miR-200b mimics and antagomirs regulates eNOS levels, and established that miR-200b physiologically limits eNOS expression during hypoxia. Furthermore, we demonstrated that the specific ablation of the hypoxic induction of miR-200b in HUVECs restored eNOS-driven hypoxic NO release to the normoxic levels. To determine whether miR-200b might be the only miRNA that had this effect, we utilized Next Generation Sequencing (NGS) to follow hypoxia-induced changes in the miRNA levels in HUVECS and found 83 novel hypoxamiRs, with two candidate miRNAs besides miR-200b that could potentially influence eNOS levels. Taken together, the data establish miR-200b-eNOS regulation as a first hypoxamiR-based mechanism that limits NO bioavailability during hypoxia in endothelial cells, and show that hypoxamiRs could become useful therapeutic targets for cardiovascular diseases and other hypoxic-related diseases including various types of cancer.
