Abstract
Cervical cancer (CC) poses a significant health threat in women globally. MicroRNA clusters (MCs), comprising multiple miRNA-encoding genes, are pivotal in gene regulation. Various factors, including circular RNA and DNA methylation, govern MC expression. Dysregulated MC expression correlates strongly with CC development via promoting the acquisition of cancer hallmarks. Certain MCs show promise for diagnosis, prognosis and therapy selection due to their distinct expression patterns in normal, premalignant and tumor tissues. This review explains the regulation and biological functions of MCs and highlights the clinical relevance of abnormal MC expression in CC.

Exp Cell Res 2023; 433:113828.

Abstract
Allergic asthma is a chronic inflammatory disease of airways involving complex mechanisms, including MAS-related GPR family member X2 (MRGPRX2) and its orthologue MRGPRB2 on mast cells (MCs). Although miRNAs have been previously shown to related to allergic asthma, the role of miR-212/132 in this process has not been studied. In this study, the predicted pairing of miRNAs and MRGPRX2 (MRGPRB2) mRNAs was carried out by online databases and the function was verify using in vivo and in vitro experiments. Database prediction showed that miR-212/132 interact with MRGPRX2 and MRGPRB2. miR-212/132 mimics alleviated MRGPRB2 mRNA expression as well as pathology changes in lungs and AHR of mice with airway inflammation in vivo. The expression level of MRGPRB2 in the mice lungs after inhaled OVA was also decreased by miR-212/132 mimics. Meanwhile, miR-212/132 inhibited MCs degranulation and cytokines release triggered by C48/80 in vitro. Further, ASAP1 (ARF GTPase-Activating Protein 1) was selected from the junction related pathways using RNAseq and KEGG enrichment. ASAP1 mRNA level was upregulated in airway inflammation and MCs activation and decreased by miR-212/132 mimics. miR-212/132 attenuated OVA-induced airway inflammation by inhibiting MCs activation through MRGPRX2 and ASAP1.

Abstract
The SMAD family member 2 (SMAD2), a member of the TGF-beta superfamily, executes a significant part in the oogenesis and ovulation process. A genome-wide selective sweep analysis also found SMAD2 was different in the fertility groups of Laoshan dairy goats; whether this gene was linked to litter size was unknown. Therefore, SMAD2 was chosen to study its effects on Shaanbei white cashmere goat reproduction and mRNA expression profile. Herein, the mRNA expression level of SMAD2 was firstly determined in female goat tissues, revealing significant differences in mRNA levels of different tissues (p < 0.05), including ovary tissue, indicating a potential role for SMAD2 in goat prolificacy. Then, using six pairs of primers, only one indel locus (P3-Del-12-bp) was found to be polymorphic in goat SMAD2 (n = 501). ANOVA also revealed that a P3-Del-12-bp deletion was significantly related to first-born litter size (p = 0.037). The Chi-square (χ2) test revealed that the ID genotype was significantly more prevalent in mothers with multiple lambs (p = 0.01), indicating that heterozygous individuals (ID) are more likely to produce multiple lambs. Our findings suggest that the SMAD2 gene's P3-Del-12-bp deletion could be used to improve goat breeds by assisting with litter size selection.

Abstract
Cyclin-dependent kinases (CDKs) regulate cell division at multiple levels. Aberrant proliferation induced by abnormal cell cycle is a hallmark of cancer. Over the past few decades, several drugs that inhibit CDK activity have been created to stop the development of cancer cells. The third generation of selective CDK4/6 inhibition has proceeded into clinical trials for a range of cancers and is quickly becoming the backbone of contemporary cancer therapy. Non-coding RNAs, or ncRNAs, do not encode proteins. Many studies have demonstrated the involvement of ncRNAs in the regulation of the cell cycle and their abnormal expression in cancer. By interacting with important cell cycle regulators, preclinical studies have demonstrated that ncRNAs may decrease or increase the treatment outcome of CDK4/6 inhibition. As a result, cell cycle-associated ncRNAs may act as predictors of CDK4/6 inhibition efficacy and perhaps present novel candidates for tumor therapy and diagnosis.

Abstract
Although ongoing medical research is working to find a cure for a variety of cancers, it continues to be one of the major causes of death worldwide. Chemotherapy and immunotherapy, as well as surgical intervention and radiation therapy, are critical components of cancer treatment. Most anti-cancer drugs are given systemically and distribute not just to tumor tissues but also to normal tissues, where they may cause side effects. Furthermore, because anti-cancer drugs have a low delivery efficiency, some tumors do not respond to them. As a result, tumor-targeted drug delivery is critical for improving the safety and efficacy of anti-cancer treatment. Exosomes are microscopic extracellular vesicles that cells produce to communicate with one another. MicroRNA (miRNA), long non-coding RNA (lncRNA), small interfering RNA (siRNA), DNA, protein, and lipids are among the therapeutic cargos found in exosomes. Recently, several studies have focused on miRNAs as a potential therapeutic element for the treatment of cancer. Mesenchymal stem cells (MSC) have been known to have angiogenic, anti-apoptotic, anti-inflammatory and immunomodulatory effects. Exosomes derived from MSCs are gaining popularity as a non-cellular alternative to MSC-based therapy, as this method avoids unwanted lineage differentiation. Therefore more research have focused on transferring miRNAs to mesenchymal stem cells (MSC) and targeting miRNA-loaded exosomes to cancer cells. Here, we initially gave an overview of the characteristics and potentials of MSC as well as the use of MSC-derived exosomes in cancer therapy. Finally, we emphasized the utilization of MSC-derived exosomes for miRNA delivery in the treatment of cancer.

Abstract
Cervical cancer (CC) is a preventable disease using proven interventions, specifically prophylactic vaccination, pervasive disease screening, and treatment, but it is still the most frequently diagnosed cancer in women worldwide. Patients with advanced or metastatic CC have a very dismal prognosis and current therapeutic options are very limited. Therefore, understanding the mechanism of metastasis and discovering new therapeutic targets are crucial. New sequencing tools have given a full visualization of the human transcriptome's composition. Non-coding RNAs (NcRNAs) perform various functions in transcriptional, translational, and post-translational processes through their interactions with proteins, RNA, and even DNA. It has been suggested that ncRNAs act as key regulators of a variety of biological processes, with their expression being tightly controlled under physiological settings. In recent years, and notably in the past decade, significant effort has been made to examine the role of ncRNAs in a variety of human diseases, including cancer. Therefore, shedding light on the functions of ncRNA will aid in our better understanding of CC. In this review, we summarize the emerging roles of ncRNAs in progression, metastasis, therapeutics, chemo-resistance, human papillomavirus (HPV) regulation, metabolic reprogramming, diagnosis, and as a prognostic biomarker of CC. We also discussed the role of ncRNA in the tumor microenvironment and tumor immunology, including cancer stem cells (CSCs) in CC. We also address contemporary technologies such as antisense oligonucleotides, CRISPR-Cas9, and exosomes, as well as their potential applications in targeting ncRNAs to manage CC.

Abstract
Recently, kinesin family member 21B (KIF21B) has been reported to be an oncogene in non-small cell lung cancer and hepatocellular carcinoma. However, the functional role of KIF21B and related molecular mechanisms in gastric cancer (GC) remain largely uncovered. In this study, online bioinformatics analysis showed that KIF21B was overexpression in GC and predicted poor prognosis. Consistently, we found that the protein expression of KIF21B was upregulated in GC tissues compared with adjacent tissues by immunohistochemistry. Knockdown of KIF21B significantly suppressed cell proliferation, migration and invasion in GC cell lines (AGS and SNU-5) using Cell counting kit‑8 (CCK-8) assay, colony formation and transwell assay. KIF21B was confirmed as the target of miR-132-3p in GC cells by luciferase reporter assay. Moreover, miR-132-3p was down-regulated and KIF21B expression was upregulated in GC tissues. Overexpression of KIF21B reversed the miR-132-3p-mediated suppressive effects on GC cell proliferation, migration and invasion. Furthermore, miR-132-3p overexpression downregulated the protein levels of Wnt1, c-Myc, β-catenin, proliferating cell nuclear antigen (PCNA) and N-cadherin, and upregulated E-cadherin expression in GC cells, which were all alleviated after KIF21B overexpression. In conclusion, our findings indicate that down-regulation of KIF21B by miR-132-3p suppresses cellular functions in GC, which might be linked to reduced Wnt/β-catenin signaling.

Abstract
The SMAD protein family plays crucial roles in reproduction as a downstream target genes of the TGFβ signaling pathway. Many studies have focused on the expression change exploration of SMADs during testicular development and investigation of SMAD2 in hormone synthesis regulation. However, little attention has been given to determining the regulatory mechanism of SMADs in sheep testes. In the present study, we first detected SMAD mRNA expression levels in three-month-old (3 M), six-month-old (6 M), nine-month-old (9 M) and two-year-old (2Y) sheep testes. Different SMADs showed various expression patterns. In addition, the subcellular localization of SMAD2 was also analyzed, and Sertoli cells (SCs), Leydig cells (LCs) and spermatogonia presented mainly positive staining. Protein and nucleic acid sequence alignment showed that the SMAD2 gene was extremely homologous between various species. SMAD2 interference RNA was transfected into sheep LCs to examine the cell proliferation and hormone levels. The testosterone level was significantly decreased, and cell proliferation efficiency presented the same trend (P < 0.05). Moreover, SMAD2 downregulation promoted cell apoptosis (P < 0.05) and changed the cell cycle. In total, our results revealed that downregulating the expression of SMAD2 can effectively inhibit testosterone levels by affecting cell proliferation and apoptosis.

Abstract
Pituitary adenomas (PAs) are common cranial tumors that affect the quality of life in patients. Early detection of PA is beneficial for avoiding clinical complications of this disease and increasing the quality of life. Noncoding RNAs, including long noncoding RNA, miRNA and circRNA, regulate protein expression, mostly by inhibiting the translation process. Studies have shown that dysregulation of noncoding RNAs is associated with PA. Hence understanding the expression pattern of noncoding RNAs can be considered a promising method for developing biomarkers. This article reviews data on the expression pattern of dysregulated noncoding RNAs involved in PA. Possible molecular mechanisms by which the dysregulated noncoding RNA could possibly induce PA are also described.

Abstract
Cervical cancer (CC) is one of the leading causes of death in women due to cancer and a major concern in the developing world. Persistent human papilloma virus (HPV) infection is the major causative agent for CC. Besides HPV infection, genetic and epigenetic factors including microRNA (miRNA) also contribute to the malignant transformation. Earlier studies have revealed that miRNAs participate in cell proliferation, invasion and metastasis, angiogenesis, and chemoresistance processes by binding and inversely regulating the target oncogenes or tumor suppressor genes. Based on functions and mechanistic insights, miRNAs have been identified as cellular modulators that have an enormous role in diagnosis, prognosis, and cancer therapy. Signatures of miRNA could be used as diagnostic markers which are necessary for early diagnosis and management of CC. The therapeutic potential of miRNAs has been shown in CC; however, more comprehensive clinical trials are required for the clinical translation of miRNA-based diagnostics and therapeutics. Understanding the molecular mechanism of miRNAs and their target genes has been useful to develop miRNA-based therapeutic strategies for CC and overcome chemoresistance. In this review, we summarize the role of miRNAs in the development, progression, and metastasis of CC as well as chemoresistance. Further, we discuss the diagnostic and therapeutic potential of miRNAs to overcome chemoresistance and treatment of CC.

Abstract
Cancer as one of the leading causes of human deaths has always been one of the main health challenges in the world. Despite recent advances in therapeutic and diagnostic methods, there is still a high mortality rate among cancer patients. Late diagnosis is one of the main reasons for the high ratio of cancer related deaths. Therefore, it is required to introduce novel early detection methods. Various molecular mechanisms are associated with the tumor progression and metastasis. MicroRNAs (miRNAs) are a class of non-coding RNAs (ncRNAs) family that has important functions in regulation of the cellular processes such as cell proliferation, apoptosis, and tumor progression. Moreover, they have higher stability in body fluids compared with mRNAs which can be introduced as non-invasive diagnostic markers in cancer patients. MiR-132 has important functions as tumor suppressor or oncogene in different cancers. In the present review, we have summarized all of the studies which have been reported the role of miR-132 during tumor progressions. We categorized the miR-132 target genes based on their cell and molecular functions. Although, it has been reported that the miR-132 mainly functions as a tumor suppressor, it has also oncogenic functions especially in pancreatic tumors. MiR-132 mainly exerts its roles during tumor progressions by regulation of the transcription factors and signaling pathways. Present review clarifies the tumor specific molecular mechanisms of miR-132 to introduce that as an efficient non-invasive diagnostic marker in various cancers.

Abstract
Background This study aimed to explore and identify key genes and signaling pathways that contribute to the progression of cervical cancer to improve prognosis. Methods Three gene expression profiles (GSE63514, GSE64217 and GSE138080) were screened and downloaded from the Gene Expression Omnibus database (GEO). Differentially expressed genes (DEGs) were screened using the GEO2R and Venn diagram tools. Then, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed. Gene set enrichment analysis (GSEA) was performed to analyze the three gene expression profiles. Moreover, a protein–protein interaction (PPI) network of the DEGs was constructed, and functional enrichment analysis was performed. On this basis, hub genes from critical PPI subnetworks were explored with Cytoscape software. The expression of these genes in tumors was verified, and survival analysis of potential prognostic genes from critical subnetworks was conducted. Functional annotation, multiple gene comparison and dimensionality reduction in candidate genes indicated the clinical significance of potential targets. Results A total of 476 DEGs were screened: 253 upregulated genes and 223 downregulated genes. DEGs were enriched in 22 biological processes, 16 cellular components and 9 molecular functions in precancerous lesions and cervical cancer. DEGs were mainly enriched in 10 KEGG pathways. Through intersection analysis and data mining, 3 key KEGG pathways and related core genes were revealed by GSEA. Moreover, a PPI network of 476 DEGs was constructed, hub genes from 12 critical subnetworks were explored, and a total of 14 potential molecular targets were obtained. Conclusions These findings promote the understanding of the molecular mechanism of and clinically related molecular targets for cervical cancer.

[PMID: 34182078 DOI: 10.1016/j.tox.2021.152842] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Revised: 06/20/2021] [Accepted: 06/24/2021] [Indexed: 11/18/2022]
Abstract
Vinclozolin (VCZ) is a fungicide with antiandrogen activity. Exposure to VCZ in maternal uterus may cause uterine, ovarian and testicular damage, hypospadias and prostate abnormality in the offspring. Hippo pathway, which is highly conservative and may be activated by miR132 and miR195a, can control organ size and tissue regeneration, and participate in injury and deformity. In the present study, VCZ was found to have caused penile malformation in the male offspring and also induced "small testis" when it was administered to the pregnant mice orally at a dose of 400 mg kg-1 day-1 on Days 12-18 of gestation. At 1, 3 and 7 weeks of age, VCZ could increase miR132, Mst1, Sav1, phosphorylated Yes-associated protein (pYap) and pLats, and decrease Yap in offspring penises and testes. Besides, it could also raise miR195a both in the testes of 1, 7-week and in the penises of all the three ages. In addition, we found the levels of some cyclin (Ccn) genes elevated in the testes, the expression of the androgen receptor (Ar) gene dereased and Jnks changed in the penises of offspring aged 1, 3 and 7 weeks. The results suggest that that gestational VCZ exposure could not only increase miR132 and miR195a in penises and testes of the offspring, but also activate Hippo pathway and down-regulate Ar. These may directly inhibit cell proliferation, accelerate cell death by up-regulating the expression of some Ccns, and ultimately lead to penile and testicular damage and malformations in the offspring.

Abstract
MicroRNAs are a group of short non-coding RNAs (miRNAs), which are epigenetically involved in gene expression and other cellular biological processes and can be considered as potential biomarkers for cancer detection and support for treatment management. This review aims to amass the evidence to reach the molecular mechanism and clinical significance of miR-132 in different types of cancer. Dysregulation of miR-132 level in various types of malignancies, including hepatocellular carcinoma, breast cancer, colorectal cancer, gastric cancer, lung cancer, prostate cancer, osteosarcoma, pancreatic cancer, and ovarian cancer have reported, significantly decrease in its level, which can be indicated to its function as a tumor suppressor. miR-132 is involved in cell proliferation, migration, and invasion through cell cycle pathways, such as PI3K, TGFβ or hippo signaling pathways, or on oncogenes such as Ras, AKT, mTOR, glycolysis. miR-132 could be potentially a candidate as a valuable biomarker for prognosis in various cancers. Through this study, we proposed that miR-132 can potentially be a candidate as a prognostic marker for early detection of tumor development, progression, as well as metastasis.

Abstract
BACKGROUND The long non-coding RNA (lncRNA) small nucleolar RNA host gene 5 (SNHG5) has been verified as a crucial regulator in many types of tumours but not clear in cervical cancer (CC). This study aims to investigate the effect and further mechanisms of lncRNA SNHG5 in CC. METHODS The expression of SNHG5 and miR-132, as well as SOX4 (sex-determining region Y-box 4) mRNA expression were determined by quantitative real-time PCR (qRT-PCR). The protein level of SOX4 and epithelial-mesenchymal transition (EMT)-related proteins were evaluated by western blot. Then, Edu and Transwell assay were performed to assess the proliferation, migration and invasion of CC cells. RNA immunoprecipitation (RIP) and RNA pull-down assay were conducted to explore the relationship between SNHG5 and miR-132. RESULTS SNHG5 and SOX4 were upregulated, and miR-132 was downregulated in CC tissues and cell lines. SNHG5 was positively correlated with FIGO stage (p = .003) and lymph node metastasis (p = .001). Pearson's correlation analysis conveyed that SNHG5 was positively correlated with SOX4, and miR-132 was negatively correlated with SOX4 and SNHG5. Knockdown of SNHG5 in vitro reduced CC cell proliferation, migration and invasion through regulating miR-132. Moreover, overexpression of miR-132 restrained CC cell proliferation, migration, and invasion through targeting SOX4, and SNHG5 enhanced SOX4 expression via negatively regulating miR-132. CONCLUSION SNHG5 promotes SOX4 expression to accelerate CC cell proliferation, migration and invasion through negatively regulating miR-132.

Abstract
Background: Glioma is an aggressive type of brain tumor that originated from neuroglia cells, accounts for about 80% of all malignant brain tumors. Glioma aggressiveness has been associated with extreme cell proliferation, invasion of malignant cells, and resistance to chemotherapies. Due to resistance to common therapies, glioma affected patients’ survival has not been remarkably improved. ZEB2 (SIP1) is a critical transcriptional regulator with various functions during embryonic development and wound healing that has abnormal expression in different malignancies, including brain tumors. ZEB2 overexpression in brain tumors is attributed to an unfavorable state of the malignancy. Therefore, we aimed to investigate some functions of ZEB2 in two different glioblastoma U87 and U373 cell lines. Methods: In this study, we investigated the effect of ZEB2 knocking down on the apoptosis, cell cycle, cytotoxicity, scratch test of the two malignant brain tumor cell lines U87 and U373. Besides, we investigated possible proteins and microRNA, SMAD2, SMAD5, and miR-214, which interact with ZEB2 via in situ analysis. Then we evaluated candidate gene expression after ZEB2-specific knocking down. Results: We found that ZEB2 suppression induced apoptosis in U87 and U373 cell lines. Besides, it had cytotoxic effects on both cell lines and reduced cell migration. Cell cycle analysis showed cell cycle arrest in G0/G1 and apoptosis induction in U87 and U373 cell lines receptively. Also, we have found that SAMAD2/5 expression was reduced after ZEB2-siRNA transfection and miR-214 upregulated after transfection. Conclusions: In line with previous investigations, our results indicated a critical oncogenic role for ZEB2 overexpression in brain glioma tumors. These properties make ZEB2 an essential molecule for further studies in the treatment of glioma cancer.

Abstract
Aim To explore the role and potential mechanism of circSND1 in cervical cancer (CC). Main Methods qRT-PCR was used to determine the expression of circSND1 in tumor necrosis factor-α (TNF-α)-treated HeLa cells. CircSND1 overexpression and knockdown were performed to indicate the functional role of circSND1 in vitro and in vivo. Luciferase assay was used to analyze promoter activity. The expression and regulation of circSND1, miR-125a-3p and FUT6 were evaluated using EGFP fluorescent reporter assay and rescue experiments. Immunofluorescence and Western blot assays were used to analyze the activation of nuclear factor-κB (NF-κB). Results In HeLa cells, TNF-α up-regulated the expression of circSND1 by activating the NF-κB signaling pathway. Overexpression of circSND1 significantly increased the migration and invasion and the epithelial–mesenchymal transition (EMT) process of CC cells, and promoted tumor metastasis in xenograft nude mouse model, whereas down-regulation of circSND1 exerted opposite effects. Furthermore, circSND1 enhanced the expression of FUT6 via sponging miR-125a-3p, and FUT6 activated NF-κB signaling pathway. Conclusion We found that circSND1 promoted the expression of FUT6 and the malignant behavior of cervical cancer through the ceRNA mechanism, and there was a TNF-α/NF-κB/circSND1/miR-125a-3p/FUT6/NF-κB positive feedback pathway between them, which suggests that circSND1 can be a promising prognostic marker and therapeutical target for cervical cancer.

Abstract
The ability of tumor cells to spread from their origin place and form secondary tumor foci is determined by the epithelial-mesenchymal transition process. In epithelial tumors such as prostate cancer (PCa), the loss of intercellular interactions can be observed as a change in expression of polarity proteins. Epithelial cells acquire ability to migrate, what leads to the formation of distal metastases. In recent years, the interest in miRNA molecules as potential future treatment options has increased. In tumor microenvironment, miRNAs have the ability to regulate signal transduction pathways, where they can act as suppressors or oncogenes. MiRNAs are secreted by cancer cells, and the changes in their expression levels are closely related to a cancer progression, including epithelial-mesenchymal transition. These molecules offer new diagnostic and therapeutic possibilities. Therapeutics which make use of synthesized RNA fragments and mimic or block miRNAs affected in PCa, may lead to inhibition of tumor progression and even disease re-emission. Based on appropriate qualification criteria, we conducted a selection process to identify scientific articles describing miRNAs and their relation to epithelial-mesenchymal transition in PCa patients. The studies were published in English on Pubmed, Scopus and the Web of Science before August 08, 2019. Hazard ratios (HRs) and 95% confidence intervals (CI) as well as total Gleason score were used to assess the concordance between miRNAs and presence of metastases. A total of 13 studies were included in our meta-analysis, representing 1608 PCa patients and 15 miRNA molecules. Our study clarifies a relationship between the clinicopathological features of PCa and the aberrant expression of several miRNA as well as the complex mechanism of miRNA molecules involvement in the induction and promotion of the metastatic mechanism in PCa.

Abstract
Gynecologic cancers involve the female genital organs, such as the vulva, vagina, cervix, endometrium, ovaries, and fallopian tubes. The occurrence and frequency of gynecologic cancer depends on personal lifestyle, history of exposure to viruses or carcinogens, genetics, body shape, and geographical habitat. For a long time, research into the molecular biology of cancer was broadly restricted to protein-coding genes. Recently it has been realized that non-coding RNAs (ncRNA), including long noncoding RNAs (LncRNAs), microRNAs, circular RNAs and piRNAs (PIWI-interacting RNAs), can all play a role in the regulation of cellular function within gynecological cancer. It is now known that ncRNAs are able to play dual roles, i.e. can exert both oncogenic or tumor suppressive functions in gynecological cancer. Moreover, several clinical trials are underway looking at the biomarker and therapeutic roles of ncRNAs. These efforts may provide a new horizon for the diagnosis and treatment of gynecological cancer. Herein, we summarize some of the ncRNAs that have been shown to be important in gynecological cancers.

Abstract
5-Fluorouracil (5-FU)-based chemotherapy is the first-line option for patients with advanced colorectal cancer (CRC). However, the development of chemoresistance is the primary cause of treatment failure. Halofuginone (HF), a small molecule alkaloid derived from febrifugine, has been demonstrated to exert strong anti-proliferative effects. However, to the best of our knowledge, whether HF inhibits the progression of 5-FU-resistant human CRC HCT-15/FU cells, and the underlying mechanisms, remain unknown. In the present study, the effects of HF on HCT-15/FU cells were assessed in vitro. The results revealed that HF inhibited HCT-15/FU cell viability as demonstrated by the MTT and colony formation assays. Following treatment of HCT-15/FU cells with HF, the migratory and invasive capacities of the cells were significantly decreased. MicroRNA (miRNA/miR)-sequencing data, subsequent miRNA trend analysis and reverse transcription-quantitative PCR all demonstrated that miR-132-3p expression was increased following treatment with HF in a dose-dependent manner. Western blot analysis indicated that following treatment with HF, the expression levels of proteins associated with proliferation, invasion and metastasis in cells were markedly downregulated. These results suggested that HF inhibited the proliferation, invasion and migration of HCT-15/FU cells by upregulating the expression levels of miR-132-3p. Therefore, miR-132-3p may serve as a molecular marker, which may be used to predict CRC resistance to 5-FU, and HF may serve as a novel clinical treatment for 5-FU-resistant CRC.

Abstract
Numerous findings have demonstrated that MicroRNAs dysregulation plays a key role in many neoplasms, including oral squamous cell carcinoma (OSCC), yet the potential mechanisms of microRNAs in chemo-resistance remain elusive. Here, we analyzed the miR-132 expression in OSCC tissues and OSCC cell lines, and explored it role and mechanisms on invasion and migration and cisplatin (CDDP)-induced cell death. The clinical tissues of 37 patients with OSCCs and paired normal tissues were collected. The miR-132 expression in OSCC tissues and cell lines were detected by reverse transcription-quantitative polymerase chain reation (RT-qPCR). The in vitro repopulation models were established to mimic the biological processes of OSCC. The results showed that miR-132 expression was significantly decreased in the OSCC tissues and CDDP resistant OSCC cell line (CAL-27/CDDP). miR-132 mimic inhibited cell proliferation, invasion, migration and enhanced the pro-apoptotic ability of CDDP. On the contrary, downregulation of miR-132 promoted proliferation, invasion, migration and conferred OSCC cell resistance to CDDP-induced apoptosis in vitro. The TGF-β1 expression in OSCC tissues and CAL-27/CDDP cells was significantly higher. miR-132 significantly inhibited the TGF-β1/Smad2/3 signals. TGF-β1 upregulation significantly promoted OSCC cell proliferation and resumed OSCC cell chemo-resistance in the miR-132 overexpressing cells, which is contrary to the function of miR-132. In summary, miR-132 acts as a tumor suppressor and exerts a substantial role in inhibiting the proliferation, invasion, and enhanced the chemosensitivity to CDDP of OSCC via regulating TGF-β1/Smad2/3 signals in vitro. These observations indicate that miR-132 may be a suitable therapeutic target for the treatment of OSCC.

[PMID: 32862489 PMCID: PMC7755761 DOI: 10.1002/jcla.23511] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 07/05/2020] [Accepted: 07/07/2020] [Indexed: 01/01/2023] Open
Abstract
Background Circulating microRNAs that post‐transcriptionally regulate gene expressions have been reported as promising biomarkers in cancer monitoring. This study was to identify the potential role of circulating miR‐212 in gastric cancer and whether it could serve as a novel biomarker for gastric cancer. Methods We detected the serum levels of miR‐212 in 100 health people and 110 gastric cancer patients and analyzed the relationships of the serum level of miR‐212 with gastric cancer. We detected the expression of miR‐212 in human gastric mucosal epithelial cell line (GES‐1) and human gastric cancer cell lines (NCI‐N87 and SNU‐16) using qRT‐PCR. Then, we detected the role of 5‐aza‐deoxycytidine on the epigenetic regulation of miR‐212 in human gastric cancer cell lines. Furthermore, luciferase reporter assay was used to detect binding activity of miR‐212 on SOX4 mRNA, and their functions on the cell proliferation and apoptosis. Results The expression of miR‐212 was higher in health people than that in gastric cancer patients, higher in gastric mucosal epithelial cell line than that in gastric cancer cells. miR‐212 can be a circulating biomarker and an independent prognostic factor of gastric cancer. Moreover, miR‐212 can directly regulate the 3′UTR of SOX4 mRNA to suppress p53 and Bax, resulting gastric cancer cells proliferation inhibition and apoptosis induction. Conclusion Our study demonstrated that miR‐212 was epigenetically downregulated in gastric cancer, and resulting low level of miR‐212 can be a potential circulating biomarker and poor prognosis predicator of gastric cancer.

Abstract
Although a potentially preventable disease, cervical cancer (CC) is the second most commonly diagnosed gynaecological cancer with at least 530,000 new cases annually, and the prognosis with CC is still poor. Studies suggest that aberrant expression of microRNA (miRNA) contributes to the progression of CC. As a group of small non-coding RNA with 18-25 nucleotides, miRNA regulate about one-third of all human genes. They function by repressing translation or inducing mRNA cleavage or degradation, including genes involved in diverse and important cellular processes, including cell cycling, proliferation, differentiation, and apoptosis. Results showed that misexpression of miRNA is closely related to the onset and progression of CC. This review will provide an overview of the function of miRNA in CC and the mechanisms involved in cervical carcinogenesis.

Abstract
Background It has been shown that miR-144-3p regulates cell proliferation, apoptosis, migration and invasion in various cancers. However, the function and expression of miR-144-3p in colorectal cancer (CRC) remained obscure. Methods Immunohistochemical (IHC) staining was performed to investigate the protein expression of BCL6 in CRC tissues. The effect of BCL6 and miR-144-3p on CRC cells was explored through methylthiazolyl tetrazolium (MTT) assay, colony formation and cell cycle assays. Luciferase reporter assays, reverse transcription quantitative polymerase chain reaction (RT-qPCR) and Western blot assay were carried out to determine that BCL6 is directly regulated by miR-144-3p. Results Our results showed that miR-144-3p is down-regulated in CRC and correlates with the tumor progression of CRC patients. miR-144-3p inhibits cell proliferation and delays G1/S phase transition of CRC cells. Moreover, we found that BCL6 is a new target of miR-144-3p. Furthermore, BCL6 is a mediator of miR-144-3p repression of cell proliferation and cell cycle arrest in CRC cells. miR-144-3p repression of Wnt/β-catenin signaling is mediated by BCL6 in CRC cells. Conclusions Overall, the effect of the miR-144-3p/BCL6 axis on regulating CRC carcinogenesis was demonstrated, and miR-144-3p was identified as a potential prognostic and therapeutic target in colorectal cancer.

Abstract
Cancer is a major health problem worldwide. An increasing number of researchers are studying the diagnosis, therapy and mechanisms underlying the development and progression of cancer. The study of noncoding RNA has attracted a lot of attention in recent years. It was found that frequent alterations of miRNA expression not only have various functions in cancer but also that miRNAs can act as clinical markers of diagnosis, stage and progression of cancer. MiR-212 is an important example of miRNAs involved in cancer. According to recent studies, miR-212 may serve as an oncogene or tumour suppressor by influencing different targets or pathways during the oncogenesis and the development and metastasis of cancer. Its deregulation may serve as a marker for the diagnosis or prognosis of cancer. In addition, it was recently reported that miR-212 was related to the sensitivity or resistance of cancer cells to chemotherapy or radiotherapy. Here, we summarize the current understanding of miR-212 functions in cancer by describing the relevant signalling pathways and targets. The role of miR-212 as a biomarker and its therapeutic potential in cancer is also described. The aim of this review was to identify new methods for the diagnosis and treatment of human cancers.

Abstract
Purpose:
To explore the role and potential mechanism of miR-212-3p in neuropathic
pain regulation.
Methods:
Adult male rats were used to establish chronic constriction injury (CCI) model to mimic
the neuropathic pain. Then, paw withdrawal threshold (PWT) and paw withdrawal thermal latency
(PWL) were determined. The concentrations of interleukin 1 beta (IL-1β), interleukin 6 (IL-6) and
tumor necrosis factor-alpha (TNF-α) were measured with enzyme-linked immune sorbent assay
(ELISA) kit and the expression of miR-212-3p was measured by real time quantitative PCR (RTqPCR).
Besides, miR-212-3p agomir was intrathecally injected into CCI rats and the expression of
key apoptotic proteins was determined by western blot. Furthermore, dual-luciferase reporter assay
was used to determine the binding of miR-212-3p and 3’ untranslated regions (3’UTR) of NaV1.3
and the expression levels of NaV1.3 were measured by western blot and RT-qPCR.
Results:
In the CCI group, the PWT and PWL were significantly decreased and IL-1β, IL-6 and
TNF-α were increased. miR-212-3p was decreased in response to CCI. The intrathecal injection of
miR-212-3p agomir into CCI rats improved the PWT and PWL, decreased the IL-1β, IL-6 and
TNF-α, decreased the expression levels of BCL2 associated X, apoptosis regulator (Bax), cleaved
caspase-3 and increased the expression levels of BCL2 apoptosis regulator (Bcl-2). The results of
dual--luciferase reporter assay showed that miR-212-3p could directly bind with 3’UTR of NaV1.3.
The expression of NaV1.3 was up-regulated in CCI rats who were intrathecally injected with miRctrl,
whereas it decreased in CCI rats intrathecally injected with miR-212-3p agomir.
Conclusion:
The expression of miR-212a-3p attenuates neuropathic pain by targeting NaV1.3.

Abstract
BACKGROUND Worldwide, mortality from cervical cancer in women remains high. This study aimed to investigate the expression of long noncoding RNA (lncRNA) TP73-AS1, microRNA-329-3p (miRNA-329-3p), and the SMAD2 gene and their regulatory relationships in human cervical cancer tissue and cervical cancer cell lines. MATERIAL AND METHODS Cervical cancer tissue samples (n=30) and normal control cervical tissues were studied. Cell proliferation and migration were investigated in HeLa and SiHa human cervical cancer cells using the MTT assay, crystal violet staining, wound healing assay, and the transwell assay. Expression of lncRNA TP73-AS1 and the SMAD2 gene were detected using quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot. Enrichment of miR-329-3p was measured using the RNA immunoprecipitation assay (RIPA). Targeting relationships between TP73-AS1, miR-329-3p, and SMAD2 were identified using the dual-luciferase reporter assay. A subcutaneous xenograft model was established, tumor size was measured, and SMAD2 expression was detected using immunohistochemistry. RESULTS LncRNA TP73-AS1 was overexpressed in cervical cancer tissues and cells and was associated with reduced expression of miR-329-3p. Down-regulation of lncRNA TP73-AS1 inhibited cell proliferation, migration and invasion and increased miR-329-3p expression. Expression of SMAD2 down-regulated miR-329-3p and was associated with increased expression of TP73-AS1. LncRNA TP73-AS1 knockdown resulted in miR-329-3p silencing. In tumor xenografts, expression of TP73-AS1 reduced the tumor volume and down-regulated the expression levels of the SMAD2 gene. CONCLUSIONS LncRNA TP73-AS1 promoted proliferation of cervical cancer cell lines by targeting miR-329-3p to regulate the expression of the SMAD2 gene. A regulatory network was formed between lncRNA TP73-AS1, miR-329-3p, and SMAD2.

Abstract
Cancer cells have the unique ability to overcome natural defense mechanisms, undergo unchecked proliferation and evade apoptosis. While chemotherapeutic drugs address this, they are plagued by a long list of side effects and have a poor success rate. This has spurred researchers to identify safer bioactive compounds that possess chemopreventive and therapeutic properties. A wide range of experimental as well as epidemiological data encourage the use of dietary agents to impede or delay different stages of cancer. In the present study, we have examined the anti-ancer property of ubiquitous phytochemical quercetin by using cell viability assay, flow cytometry, nuclear morphology, colony formation, scratch wound assay, DNA fragmentation and comet assay. Further, qPCR analysis of various genes involved in apoptosis, cell cycle regulation, metastasis and different signal transduction pathways was performed. Proteome profiler was used to quantitate the expression of several of these proteins. We find that quercetin decreases cell viability, reduces colony formation, promotes G2-M cell cycle arrest, induces DNA damage and encourages apoptosis. Quercetin induces apoptosis via activating both apoptotic pathways with a stronger effect of the extrinsic pathway relying on the combined power of TRAIL, FASL and TNF with up-regulation of caspases and pro-apoptotic genes. Quercetin could inhibit anti-apoptotic proteins by docking studies. Further, quercetin blocks PI3K, MAPK and WNT pathways. Anticancer effect of quercetin observed in cell-based assays were corroborated by molecular biology studies and yielded valuable mechanistic information. Quercetin appears to be a promising candidate with chemopreventive and chemotherapeutic potential and warrants further research.

Abstract
Cervical cancer is as a kind of cancer beginning from the cervix. Given that cervical cancer could be observed in women who infected with papillomavirus, regular oral contraceptives, and multiple pregnancies. Early detection of cervical cancer is one of the most important aspects of the therapy of this malignancy. Despite several efforts, finding and developing new biomarkers for cervical cancer diagnosis are required. Among various prognostic, diagnostic, and therapeutic biomarkers, miRNA have been emerged as powerful biomarkers for detection, treatment, and monitoring of response to therapy in cervical cancer. Here, we summarized various miRNAs as an employable platform for prognostic, diagnostic, and therapeutic biomarkers in the treatment of cervical cancer.

Abstract
MiRNAs have immerged as essential modulators of key cellular procuresses involved in post-transcriptional regulation of the human transcriptome. They are essential components of complex regulatory networks that modulate most important physiological functions of cells. MicroRNA-155 (miR-155) is a multifaceted regulator of cell proliferation, cell cycle, development, immunity and inflammation that plays pivotal, and sometimes contradictory, roles in numerous cancers including esophageal cancer. Here, we review the intricate role of miR-155 in cancer by exemplifying carcinogenesis of various tumors, focusing on recent findings that may provide a link between miR-155 and esophageal cancer-related pathways.

Abstract
Cervical cancer is a common malignant tumour of the female reproductive system that seriously threatens the health of women. The aims of this study were to identify key genes and pathways and to illuminate new molecular mechanisms underlying cervical cancer. Altogether, 1829 DEGs were identified, including 794 significantly down-regulated DEGs and 1035 significantly up-regulated DEGs. GO analysis suggested that the up-regulated DEGs were mainly enriched in mitotic cell cycle processes, including DNA replication, organelle fission, chromosome segregation and cell cycle phase transition, and that the down-regulated DEGs were primarily enriched in development and differentiation processes, such as tissue development, epidermis development, skin development, keratinocyte differentiation, epidermal cell differentiation and epithelial cell differentiation. KEGG pathway analysis showed that the DEGs were significantly enriched in cell cycle, DNA replication, the p53 signalling pathway, pathways in cancer and oocyte meiosis. The top 9 hub genes with a high degree of connectivity (over 72 in the PPI network) were down-regulated TSPO, CCND1, and FOS and up-regulated CDK1, TOP2A, CCNB1, PCNA, BIRC5 and MAD2L1. Module analysis indicated that the top 3 modules were significantly enriched in mitotic cell cycle, DNA replication and regulation of cell cycle (P < 0.01). The heat map based on TCGA database preliminarily demonstrated the expression change of the key genes in cervical cancer. GSEA results were basically coincident with the front enrichment analysis results. By comprehensive analysis, we confirmed that cell cycle was a key biological process and a critical driver in cervical cancer. In conclusion, this study identified DEGs and screened the key genes and pathways closely related to cervical cancer by bioinformatics analysis, simultaneously deepening our understanding of the molecular mechanisms underlying the occurrence and progression of cervical cancer. These results might hold promise for finding potential therapeutic targets of cervical cancer.

Abstract
MicroRNAs (miRNAs) are frequently dysregulated in human cancer and can act as either potent oncogenes or tumor suppressor genes. The aberrant expression of miRNA‑409 (miR‑409) has been found in certain types of cancer, however, its expression and potential biological role in endometrial cancer remain to be fully elucidated. In the present study, a total of 16 pairs of tissue samples from 16 patients with endometrial cancer were used in the present study, each of which consisted of human endometrial cancer tissue and matched adjacent normal tissue from the same patient. The expression of miR‑409 of the tissue were detected and its associations with Ishikawa and HEC‑1B human endometrial cancer cell lines were studied. The results of the present study demonstrated that miR‑409 was downregulated in human endometrial cancer, and it suppressed the growth of Ishikawa and HEC‑1B human endometrial cancer cell lines. Bioinformatics analysis indicated that small mothers against decapentaplegic 2 (Smad2) was a putative target of miR‑409. In a luciferase reporter system, it was confirmed that Smad2 was a direct target gene of miR‑409. It was also demonstrated that Smad2 was upregulated in human endometrial cancer tissues, and this was inversely correlated with the expression of miR‑409. These findings indicated that miR‑409 targeted the Smad2 transcript and suppressed endometrial cancer cell growth, suggesting that miR‑409 has a tumor suppressive role in the pathogenesis of human endometrial cancer.

Abstract
Background MicroRNA-647 (miR-647) has been reported to repress cell tumorigenic phenotype, while the function of miR-647 in non-small cell lung cancer was obscure. Methods The effect of miR-647 and TRAF2 on A549 and H1299 cells was explored through Methyl thiazolyl tetrazolium (MTT) assay, colony formation and cell cycle assays. Luciferase reporter assays, reverse transcription quantitative PCR (RT-qPCR) and Western blot assay were carried out to determine that TRAF2 is directly regulated by miR-647. The effect of miR-647/TRAF2 axis on p65 protein level in nucleus or total was detected by Western blot assay. Results Here, we found that miR-647 was high expression in tumor that under argon-helium cryoablation treatment in contrast to the tumor under non argon-helium cryoablation treatment and inhibited cell proliferation of A549 and H1299 cells by inducing G1-S transition. TRAF2 was confirmed as a target of miR-647. TRAF2 overexpression partially rescued the suppressive function of miR-647 in A549 and H1299 cells. Moreover, we found that miR-647 repressed lung carcinogenesis by attenuating NF-κB pathway. Conclusion In all, our study demonstrates that miR-647 functions as tumor suppressor via targeting and down-regulating the expression of TRAF2 and NF-κB signaling pathway in non-small cell lung cancer.

Abstract
MicroRNAs (miRNAs) are endogenous, small non-coding RNAs known to regulate expression of protein-coding genes. A large proportion of miRNAs are highly conserved, localized as clusters in the genome, transcribed together from physically adjacent miRNAs and show similar expression profiles. Since a single miRNA can target multiple genes and miRNA clusters contain multiple miRNAs, it is important to understand their regulation, effects and various biological functions. Like protein-coding genes, miRNA clusters are also regulated by genetic and epigenetic events. These clusters can potentially regulate every aspect of cellular function including growth, proliferation, differentiation, development, metabolism, infection, immunity, cell death, organellar biogenesis, messenger signalling, DNA repair and self-renewal, among others. Dysregulation of miRNA clusters leading to altered biological functions is key to the pathogenesis of many diseases including carcinogenesis. Here, we review recent advances in miRNA cluster research and discuss their regulation and biological functions in pathological conditions.

Abstract
Double cortin-like kinase 1 (DCLK1) plays important roles during the epithelial-mesenchymal transition (EMT) process in human colorectal cancer (CRC). However, the role of DCLK1 in regulating the EMT of CRC is still poorly understood. In this study, we report evidence that DCLK1 acts as a potent oncogene to drive its extremely malignant character of EMT in an NF-κB-dependent manner in CRC cells. Mechanistic investigations showed that DCLK1 induced the NF-κBp65 subunit expression through the PI3K/Akt/Sp1 axis and activated NF-κBp65 through the PI3K/Akt/IκBα pathway during the EMT of CRC cells. Moreover, we found that silencing the expression of DCLK1 inhibited the invasion and metastasis of CRC cells in vivo. Collectively, our findings identify DCLK1 as a pivotal regulator of an EMT axis in CRC, thus implicating DCLK1 as a potential therapeutic target for CRC metastasis.

Abstract
miR-519d inhibits cell growth, migration, and invasion, but its role in gastric cancer (GC) cells is obscure. We showed that miR-519d-3p was lowly expressed in GC tissues and was associated with the clinical stage and lymph node metastasis of GC tissues. We found that miR-519d-3p repressed cell proliferation and invasion of MGC803 cells and delayed the G1/S phase transition, resulting in decreased cyclin B1 and MMP2 and increased E-cadherin levels. Furthermore, miR-519d-3p targeted and downregulated B-cell lymphoma 6 (BCL6) expression. BCL6 overexpression partially abrogated the suppressive function of miR-519d in MGC803 cells. In conclusion, our study demonstrated that miR-519d-3p functions as a tumor suppressor by targeting and downregulating the expression of BCL6 in GC cells.

Abstract
Myocardial infarction (MI), characterized by ischemia-induced cardiomyocyte apoptosis, is the leading cause of mortality worldwide. NR4A2, a member of the NR4A orphan nucleus receptor family, is upregulated in mouse hearts with MI injury. Furthermore, NR4A2 knockdown aggravates heart injury as evidenced by enlarged hearts and increased apoptosis. To elucidate the underlying mechanisms of NR4A2-regulated apoptosis, we used H9c2 cardiomyocytes deprived of serum and neonatal rat cardiomyocytes (NRCMs) exposed to hypoxia to mimic ischemic conditions in vivo. As NR4A2 knockdown aggravates cardiomyocyte apoptosis, while NR4A2 overexpression ameliorates it, NR4A2 upregulation was considered an adaptive response to ischemia-induced cardiomyocyte apoptosis. By detecting changes in LC3 and using autophagy detection tools including Bafilomycin A1, 3MA and rapamycin, we found that NR4A2 knockdown promoted apoptosis through blocking autophagic flux. This apoptotic response was phenocopied by downregulation of NR4A2 after autophagic flux was impaired by Bafilomycin A1. Further study showed that NR4A2 binds to p53 directly and decreases its levels when it inhibits apoptosis; thus, p53/Bax is the downstream effector of NR4A2-mediated apoptosis, as previously reported. Changes in p53/Bax that were regulated by NR4A2 were also detected in injured hearts with NR4A2 knockdown. In addition, miR-212-3p is the upstream regulator of NR4A2, and it could downregulate the expression of NR4A2, as well as p53/Bax. The mechanism underlying the role of NR4A2 in apoptosis and autophagy was elucidated, and NR4A2 may be a therapeutic drug target for heart failure.

Abstract
Background It has been reported that both of the miR-132/212 (micro-RNA) cluster members, miR-132 and miR-212, are downregulated in hepatocellular carcinoma. Nevertheless, the expression pattern and clinical utility of serum miR-132/212 in hepatocellular carcinoma are still unknown. Methods In this study, serum concentrations of miR-132 and miR-212 were measured in 80 hepatocellular carcinoma patients, 51 controls with chronic liver diseases and 42 healthy volunteers by using quantitative real-time polymerase chain reaction. Results In hepatocellular carcinoma patients, serum concentrations of miR-132 and miR-212 were significantly reduced and strongly correlated (r = 0.603, p < 0.001). Receiver operator characteristic analyses showed that serum miR-132 and miR-212 might have a potential role in the diagnosis of hepatocellular carcinoma. Moreover, the combination of serum miR-132, miR-212 and alpha-fetoprotein improved the diagnostic efficiency for hepatocellular carcinoma, especially in sensitivity and negative predictive value. Serum miR-132 was associated with tumour differentiation degree ( p = 0.021) and tumour-node-metastasis stage ( p = 0.002); serum miR-212 correlated with tumour size ( p = 0.023) and tumour-node-metastasis stage ( p = 0.007). Kaplan-Meier analyses indicated poorer overall survival in hepatocellular carcinoma patients with lower serum concentrations of miR-132 ( p < 0.001) and miR-212 ( p = 0.005). Conclusions Our results suggest that both components of the miR-132/212 cluster have potential roles as non-invasive serum biomarkers for diagnosis and prognosis of hepatocellular carcinoma.

Abstract
BACKGROUND Long non-coding RNAs (LncRNAs) have been demonstrated to play crucial role in tumor growth and metastasis for hepatocellular carcinoma (HCC). LncRNA FAL1 has been indicated to promote the progression of various cancers. However, the role of lncRNA FAL1 in HCC was poorly understood. METHODS The expression levels of lncRNA FAL1 in HCC tissues and cells were determined by RT-qPCR. The roles of lncRNA FAL1 on HCC cells were investigated by MTT, colony formation, transwell, RT-qPCR, and Western blotting. The miRNA binding sites of lncRNA FAL1 was predicted using RegRNA 2.0 and miR-1236 was validated to target lncRNA FAL1 by luciferase reporter assays and RT-qPCR. Finally, the expression levels of lncRNA FAL1 in serum exosome of HCC patients was also investigated and the role of exosome-mediated lncRNA FAL1 was further investigated by co-culturing with HCC cells. RESULTS This study first showed that lncRNA FAL1 was up-regulated in HCC tissues and functioned as an oncogene in HCC. LncRNA FAL1 could accelerate cell proliferation and metastasis as a ceRNA mechanism by competitively binding to miR-1236. Moreover, lncRNA FAL1 was also up-regulated in serum exosome of HCC patients and could transfer lncRNA FAL1 to HCC cells to increase their abilities of cell proliferation and migration. CONCLUSIONS Taken together, this study indicated that lncRNA FAL1 functions as an oncogenic in HCC and may be a novel diagnostic biomarker or a novel target for the treatment of HCC in future.

Abstract
Prostate cancer (PCa) is the second most commonly diagnosed malignancy and the fifth leading cause of cancer-related deaths in males worldwide. MicroRNAs (miRNAs) may serve as important regulators in PCa occurrence and development. Therefore, understanding the expression and functions of PCa-related miRNAs may be beneficial for the identification of novel therapeutic methods for patients with PCa. In this study, miRNA-212 (miR-212) was evidently downregulated in PCa tissues and several PCa cell lines. Functional assays showed that the resumption of miR-212 expression attenuated cell proliferation and invasion and increased the apoptosis of PCa. In addition, mitogen-activated protein kinase 1 (MAPK1), a well-known oncogene, was identified as a novel target of miR-212 in PCa, as confirmed by bioinformatics, luciferase reporter assay, qRT-PCR, and Western blot analysis. Furthermore, MAPK1 expression was upregulated in PCa tissues and inversely correlated with miR-212 expression. Rescue experiments also demonstrated that restored MAPK1 expression reversed the tumor-suppressing effects of miR-212 on PCa cell proliferation, invasion, and apoptosis. In conclusion, miR-212 may exert tumor-suppressing roles in PCa by regulating MAPK1 and could be a novel therapeutic target for treatment of patients with this malignancy.

Abstract
In this study, we investigated the consensus gene modules in head and neck cancer (HNC) and cervical cancer (CC). We used a publicly available gene expression dataset, GSE6791, which included 42 HNC, 14 normal head and neck, 20 CC and 8 normal cervical tissue samples. To exclude bias because of different human papilloma virus (HPV) types, we analyzed HPV16-positive samples only. We identified 3824 genes common to HNC and CC samples. Among these, 977 genes showed high connectivity and were used to construct consensus modules. We demonstrated eight consensus gene modules for HNC and CC using the dissimilarity measure and average linkage hierarchical clustering methods. These consensus modules included genes with significant biological functions, including ATP binding and extracellular exosome. Eigengen network analysis revealed the consensus modules were highly preserved with high connectivity. These findings demonstrate that HPV16-positive head and neck and cervical cancers share highly preserved consensus gene modules with common potentially therapeutic targets.

Abstract
MicroRNA‑212 (miR‑212) has been observed to be significantly deregulated in various types of human cancer. However, the clinical significance of miR‑212 and the associated molecular signaling pathways involved in the progression of renal cell carcinoma (RCC) remain unclear. In the present study, miR‑212 expression was significantly downregulated in RCC tissues compared with adjacent non‑tumor tissues. Clinical association analysis indicated that low expression of miR‑212 was prominently associated with large tumor size, advanced tumor, nodes, metastasis stage and lymph node metastasis. In vitro studies revealed that upregulation of miR‑212 inhibited cell proliferation, migration and invasion, and induced apoptosis in Caki‑1 cells. Forkhead box protein A1 (FOXA1) was identified as a direct target of miR‑212 in RCC cells via luciferase reporter assays and western blotting. In addition, FOXA1 expression was upregulated in RCC tissues compared with adjacent noncancerous tissues. An inverse correlation between FOXA1 and miR‑212 expression was observed in RCC tissues. Notably, FOXA1 overexpression partially rescued miR‑212‑mediated inhibition of cell proliferation, migration and invasion in RCC cells. These results suggested that miR‑212 suppresses RCC proliferation and invasion by modulating FOXA1, suggesting that miR‑212 may have potential as a therapeutic target in RCC.

Human thymic stromal lymphopoietin promotes the proliferation and invasion of cervical cancer cells by downregulating microRNA-132 expression. Oncol Lett 2017; 14:7910-7916.

Abstract
Thymic stromal lymphopoietin (TSLP), produced by cervical cancer (CC) cells, promotes angiogenesis, and the recruitment and functional regulation of eosinophils. It has been reported that microRNA (miR)-132 is aberrantly decreased in CC tissues. However, the function and mechanism of TSLP on the biological behaviors of CC cells is largely unknown. The aim of the present study was to investigate the effect of TSLP on the expression of miR-132 and the proliferation and invasion in vitro of CC cell lines, namely, HeLa and SiHa cells. The transcrpitional level of miR-132 was analyzed using reverse transcription-quantitative polymerase chaon reaction. The proliferation, invasion, and the expression of proliferation and invasion-related molecules in HeLa and SiHa cells in vitro were evaluated using bromodeoxyuridine cell proliferation, Matrigel invasion assays, flow cytometry and ELISA, respectively. Here, it was revealed that recombinant human TSLP (rhTSLP) downregulated the expression levels of miR-132 in HeLa and SiHa cells, and by contrast, the neutralizing antibodies for TSLP or TSLP receptor (TSLPR) upregulated miR-132 expression levels in HeLa and SiHa cells. The overexpression of miR-132 resulted in a lowered proliferation and invasiveness, decreased levels of proliferation-associated molecules marker of proliferation Ki-67 and proliferating cell nuclear antigen, and the decreased production of matrix metalloproteinase (MMP)2 and MMP9 in HeLa and SiHa cells. Compared with the control group, there was a higher level of proliferation and invasion in HeLa and SiHa cells following stimulation with rhTSLP. However, these effects induced by rhTSLP were significantly impaired in HeLa and SiHa cells with miR-132 overexpression. The results of the present study indicated that TSLP produced by CC cells downregulated miR-132 expression, and stimulated the proliferation and invasion of CC cells, thereby further promoting the development of CC.

Abstract
Cervical cancer is the third most common cancer in women worldwide. However, the underlying mechanism of occurrence and development of cervical cancer is obscure. In this study, we observed that miR-30e was downregulated in clinical cervical cancer tissues and cervical cancer cells. Next, overexpression of miR-30e reduced the cervical cancer cell growth through MTT, colony formation, EdU, and Transwell assay in SiHa and Caski cells. Subsequently, UDP-N-acetyl-D-galactosamine: polypeptide N-acetylgalactosaminyltransferase 7 (GALNT7) was identified as a potential miR-30e target by bioinformatics analysis. Moreover, we showed that miR-30e was able to bind to the 3′UTR of GALNT7 by luciferase reporter assay. In addition, the mRNA and protein levels of GALNT7 in cervical cancer cells were downregulated by miR-30e. And we validated that downregulation of GALNT7 repressed the proliferation of SiHa and Caski cells by MTT, colony formation, and Transwell assay. We identified that the restoration of GALNT7 expression was able to counteract the effect of miR-30e on cell proliferation of cervical cancer cells. Furthermore, we found that the expression levels of GALNT7 were frequently upregulated and negatively correlative to those of miR-30e in cervical cancer tissues. In addition, we validated that restoration of GALNT7 rescued the miR-30e–suppressed growth of cervical cancer xenografts in vivo. In conclusion, the current results suggest that miR-30e may function as tumor suppressors in cervical cancer through downregulation of GALNT7. Both miR-30e and its novel target, GALNT7, may play an important role in the process of cervical cancer.

Overexpression of microRNA-132 enhances the radiosensitivity of cervical cancer cells by down-regulating Bmi-1. Oncotarget 2017; 8:80757-80769.

Abstract
We examined the effects of microRNA-132 (miR-132) on Bmi-1 expression and radiosensitivity in HeLa, SiHa, and C33A cervical cancer (CC) cells and 104 CC patients. MiR-132 expression was decreased and Bmi-1 expression was increased in tumor tissues compared to adjacent normal tissues and in radiotherapy-resistant patients compared to radiotherapy-sensitive patients. MiR-132 expression and Bmi-1 mRNA expression were also negatively correlated in tumor tissues. HeLa, SiHa, and C33A cells were divided into blank, miR-132 negative control (NC), miR-132 inhibitor, miR-132 mimics, siBmi-1, and miR-132 inhibitor + siBmi-1 groups, after which expression of miR-132 and Bmi-1, and the interaction between them and cell survival, proliferation, and apoptosis were examined. Bmi-1 was confirmed as a target of miRNA-132. Survival was higher and apoptosis lower in the miR-132 inhibitor group than the blank group after various doses of radiation. By contrast, survival was lower and apoptosis higher in the miRNA-132 mimics and siBmi-1 groups than in the blank group. Moreover, miR-132 expression increased and Bmi-1 mRNA expression decreased in each group at radiation doses of 6 and 8 Gy. Finally, co-administration of radiotherapy and exogenous miR-132 inhibited the growth of HeLa cell transplant-induced tumors in nude mice more effectively than radiotherapy alone. These results suggest overexpression of miR-132 enhances the radiosensitivity of CC cells by down-regulating Bmi-1 and that miR-132 may be a useful new target for the treatment of CC.

Abstract
Unlike most epithelial malignancies which metastasize hematogenously, metastasis of epithelial ovarian cancer (EOC) occurs primarily via transcoelomic dissemination, characterized by exfoliation of cells from the primary tumor, avoidance of detachment-induced cell death (anoikis), movement throughout the peritoneal cavity as individual cells and multi-cellular aggregates (MCAs), adhesion to and disruption of the mesothelial lining of the peritoneum, and submesothelial matrix anchoring and proliferation to generate widely disseminated metastases. This exceptional microenvironment is highly permissive for phenotypic plasticity, enabling mesenchymal-to-epithelial (MET) and epithelial-to-mesenchymal (EMT) transitions. In this review, we summarize current knowledge on EOC heterogeneity in an EMT context, outline major regulators of EMT in ovarian cancer, address controversies in EMT and EOC chemoresistance, and highlight computational modeling approaches toward understanding EMT/MET in EOC.
