Karabegović I, Maas SCE, Shuai Y, Ikram MA, Stricker B, Aerts J, Brusselle G, Lahousse L, Voortman T, Ghanbari M. Smoking-related dysregulation of plasma circulating microRNAs: the Rotterdam study. Hum Genomics 2023; 17:61. [PMID: 37430296 DOI: 10.1186/s40246-023-00504-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Accepted: 06/26/2023] [Indexed: 07/12/2023] Open
Abstract
BACKGROUND MicroRNAs (miRNAs) are post-transcriptional regulators of gene expression. Differential miRNA expression, which is widely shown to be associated with the pathogenesis of various diseases, can be influenced by lifestyle factors, including smoking. This study aimed to investigate the plasma miRNA signature of smoking habits, the potential effect of smoking cessation on miRNA levels, and relate the findings with lung cancer incidence. RESULTS A targeted RNA-sequencing approach measured plasma miRNA levels in 2686 participants from the population-based Rotterdam study cohort. The association between cigarette smoking (current versus never) and 591 well-expressed miRNAs was assessed via adjusted linear regression models, identifying 41 smoking-associated miRNAs that passed the Bonferroni-corrected threshold (P < 0.05/591 = 8.46 × 10-5). Moreover, we found 42 miRNAs with a significant association (P < 8.46 × 10-5) between current (reference group) and former smokers. Then, we used adjusted linear regression models to explore the effect of smoking cessation time on miRNA expression levels. The expression levels of two miRNAs were significantly different within 5 years of cessation (P < 0.05/41 = 1.22 × 10-3) from current smokers, while for cessation time between 5 and 15 years we found 19 miRNAs to be significantly different from current smokers, and finally, 38 miRNAs were significantly different after more than 15 years of cessation time (P < 1.22 × 10-3). These results imply the reversibility of the smoking effect on plasma levels of at least 38 out of the 41 smoking-miRNAs following smoking cessation. Next, we found 8 out of the 41 smoking-related miRNAs to be nominally associated (P < 0.05) with the incidence of lung cancer. CONCLUSIONS This study demonstrates smoking-related dysregulation of plasma miRNAs, which might have a potential for reversibility when comparing different smoking cessation groups. The identified miRNAs are involved in several cancer-related pathways and include 8 miRNAs associated with lung cancer incidence. Our results may lay the groundwork for further investigation of miRNAs as potential mechanism linking smoking, gene expression and cancer.

Weng HR, Taing K, Chen L, Penney A. EZH2 Methyltransferase Regulates Neuroinflammation and Neuropathic Pain. Cells 2023; 12:1058. [PMID: 37048131 PMCID: PMC10093242 DOI: 10.3390/cells12071058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 03/24/2023] [Accepted: 03/29/2023] [Indexed: 04/03/2023] Open
Abstract
Recent studies by us and others have shown that enhancer of zeste homolog-2 (EZH2), a histone methyltransferase, in glial cells regulates the genesis of neuropathic pain by modulating the production of proinflammatory cytokines and chemokines. In this review, we summarize recent advances in this research area. EZH2 is a subunit of polycomb repressive complex 2 (PRC2), which primarily serves as a histone methyltransferase to catalyze methylation of histone 3 on lysine 27 (H3K27), ultimately resulting in transcriptional repression. Animals with neuropathic pain exhibit increased EZH2 activity and neuroinflammation of the injured nerve, spinal cord, and anterior cingulate cortex. Inhibition of EZH2 with DZNep or GSK-126 ameliorates neuroinflammation and neuropathic pain. EZH2 protein expression increases upon activation of Toll-like receptor 4 and calcitonin gene-related peptide receptors, downregulation of miR-124-3p and miR-378 microRNAs, or upregulation of Lncenc1 and MALAT1 long noncoding RNAs. Genes suppressed by EZH2 include suppressor of cytokine signaling 3 (SOCS3), nuclear factor (erythroid-derived 2)-like-2 factor (NrF2), miR-29b-3p, miR-146a-5p, and brain-specific angiogenesis inhibitor 1 (BAI1). Pro-inflammatory mediators facilitate neuronal activation along pain-signaling pathways by sensitizing nociceptors in the periphery, as well as enhancing excitatory synaptic activities and suppressing inhibitory synaptic activities in the CNS. These studies collectively reveal that EZH2 is implicated in signaling pathways known to be key players in the process of neuroinflammation and genesis of neuropathic pain. Therefore, targeting the EZH2 signaling pathway may open a new avenue to mitigate neuroinflammation and neuropathic pain.

Abstract
In numerous studies, microRNAs (miRNAs) have been authenticated to play vital roles in the pathophysiology of neuropathic pain and other neurological diseases. In our study, we focused on evaluating miR-378 and its potential effects in neuropathic pain development, as well as the underlying molecular mechanisms. Primarily, a chronic sciatic nerve injury (CCI) rat model was established. Next, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was employed to measure the expression levels of miR-378 and EZH2 mRNA; the EZH2 protein expression levels were detected by western blot. A luciferase activity assay monitored the interaction of miR-378 and EZH2. Mechanical and thermal hyperalgesia was also performed to quantitate the effects of overexpression of miR-378 or EZH2 on the CCI rats. We found that miR-378 was down-regulated in the CCI rats, and the overexpression of miR-378 produced significant relief in their pain management. EZH2 was the downstream gene of miR-378 and was negatively regulated by miR-378. The up-regulation of EZH2 reduced the inhibitory effects of miR-378 on the development of neuropathic pain in the CCI rats. miR-378 acts as an inhibitor in the progression of neuropathic pain via targeting EZH2; the miR-378/EZH2 axis may be a novel target for the diagnosis and therapy of neuropathic pain in clinical treatment.

Abstract
Background MicroRNAs (miRNAs) often appear as oncogenes or tumor suppressor genes. The aim of this research was to examine miR-132-3p and Kruppel-like factor 7 (KLF7) effects in the development of non-small cell lung cancer (NSCLC). Methods We used quantitative reverse transcription polymerase chain reaction (qRT-PCR) to determine miR-132-3p expression in tissue specimens and 6 cells (A549, H1650, H292, H1299, H1944, BEAS-2b). Luciferase report forecasted the targeting relationship between miR-132-3p and KLF7. The expression of KLF7 and interstitial protein was determined by western blot. Proliferation test and Transwell assay were adopted for examining cell development. The Cell Counting Kit-8 (CCK-8) colorimetric method was used to observe the effects of miR-132-3p and KLF7 on the proliferation, metastasis, and invasion of NSCLC tumor cells. In order to determine whether the metastasis of NSCLC tumor cells was epithelial-mesenchymal transition (EMT)-mediated, supplementary experiments with E-cadherin and vimentin were performed. Results An increased expression of miR-132-3p was detected in NSCLC. Its mimic promoted the proliferation of tumor cells. As an immediate site of miR-132-3p, KLF7 was reversely adjusted via miR-132-3p and restrained the development of tumor cells in NSCLC, the effects of which were attenuated via KLF7 over-expression. Besides, the presence of EMT-related diversions was confirmed in NSCLC. Conclusions By targeting KLF7, miR-132-3p was capable of promoting the proceeding of NSCLC tumor cells. We discovered miR-132-3p/KLF7 route may exhibit curative target for NSCLC.

Abstract
Objective Mounting research has established the role of microRNAs (miRNAs) as oncogenes or anti-oncogenes (tumor suppressors) in the development and progression of several cancers. The purpose of our current study is to delineate the roles and functional mechanisms of miR-331-3p and MLLT10 in non-small cell lung cancer (NSCLC) tumorigenesis. Patients and Methods Quantitative reverse transcription-polymerase chain reaction (RT-qPCR) was employed to measure miR-331-3p expression levels in twenty-six matched tumor tissues and non-cancerous tissues collected from patients suffering from NSCLC, and from six NSCLC cell lines separately: A549, H1650, H292, H1299, H1944 and BEAS-2b. We employed the dual-luciferase activity assay to check whether the putative gene, MLLT10, was a downstream target of miR-331-3p in NSCLC pathogenesis and development. Western blot was conducted to analyze the protein expression levels of MLLT10 (AF10), E-cadherin, Vimentin, and GAPDH. CCK-8 assay, transwell migration assay, and transwell invasion assay were carried out to observe the functions of miR-331-3p and MLLT10 on NSCLC tumor cell proliferation, metastasis, and invasion, respectively. To identify whether the metastasis of NSCLC tumor cells was EMT-mediated, supplementary experiments involving E-cadherin and Vimentin were implemented. Results miR-331-3p was downregulated in NSCLC, which promoted tumor cell proliferation, whereas the overexpression of miR-331-3p inhibited tumor cell proliferation. Being a direct target of miR-331-3p, MLLT10 was negatively modulated by miR-331-3p, which suppressed tumor cell proliferation, migration, and invasion in NSCLC. However, MLLT10 overexpression alleviated the above inhibitory effects. Furthermore, EMT-mediated metastasis was proved to be present in NSCLC. Conclusion miR-331-3p played a suppressor role in NSCLC tumor cell proliferation, EMT-mediated metastasis, and invasion by targeting MLLT10. Our findings highlighted that miR-331-3p/MLLT10 axis could be useful as a clinical diagnostic marker and therapeutic target in NSCLC patients.

Abstract
Non-small-cell lung cancer (NSCLC) is the fundamental form of lung cancer and the leading cause of cancer‑related mortality in humans. Numerous studies have identified a role for microRNAs (miRs) in cell proliferation, invasion and metastasis in numerous types of cancer, including lung cancer. In the present study, the functional roles and molecular mechanisms of miR‑28 in NSCLC tumorigenesis were investigated. Reverse transcription‑quantitative PCR (RT‑qPCR) was used to measure miR‑28 expression levels in NSCLC tumor tissues and cell lines. A dual‑luciferase assay was performed to observe the direct interaction between miR‑28 and PTEN in A549 cells. Furthermore, the effect of miR‑28 on the mRNA and protein expression levels of PTEN was examined by RT‑qPCR and western blotting, respectively. A Cell Counting kit‑8 assay was performed to identify the relationship between the miR‑28/PTEN axis and tumor cell proliferation using cells infected with lentivirus (LV)‑anti‑miR‑28 or LV‑anti‑miR‑28 + short hairpin RNA‑PTEN. miR‑28 expression was upregulated in NSCLC tumor tissues and cell lines compared with the control groups. PTEN was identified as the downstream gene of miR‑28 in NSCLC and was negatively regulated by miR‑28. In addition, miR‑28 knockdown suppressed the proliferation of A549 and H292 cells. Cells infected with LV‑anti‑miR‑28 + short hairpin RNA‑PTEN promoted tumor cell proliferation in A549 and H292 cells compared with cells infected with LV‑anti‑miR‑28. Taken together, the present study suggested that miR‑28 might serve as the promoter in the development of NSCLC by targeting PTEN. Therefore, the miR‑28/PTEN axis may serve as a potential diagnostic and therapeutic target for NSCLC.

Abstract
Objective Glioma is the most common malignant brain tumor that has high aggressiveness. The aim of this study was to investigate the potential therapeutic targets for gliomas. Materials and Methods Real-time quantitative polymerase chain reaction (RT-qPCR) was employed to calculate the expression of miRNA and genes. The connection between the expression of miR-483 and patients' overall survival rate was evaluated using Kaplan-Meier analysis. In addition, the underlying mechanism was detected using luciferase assay. Results The expression level of miR-483 was significantly decreased in glioma tissue samples and cell lines, compared to the adjacent tissues and normal cell lines. Downregulation of miR-483 or upregulation of SOX3 was associated with overall survival of glioma patients. Additionally, overexpression of miR-483 promotes cell invasion and migration and inhibits apoptosis. In addition, miR-483 directly targeted to SOX3, and the expression of miR-483 has a negative correlation with SOX3 in glioma tissues. SOX3 reversed partial functions of miR-483 on cell migration, invasion, and promoted cell apoptosis in glioma. Conclusion MiR-483 inhibited glioma cell migration, invasion, and promoted glioma cell apoptosis by targeting SOX3. MiR-483 maybe acted as a potential target for the treatment of glioma.

Abstract
MicroRNAs (miRNAs) play important roles in the cancer biology such as proliferation, differentiation, and apoptosis. The pivotal roles that miRNA expression plays, make them ideal candidates for detection of cancer progression as well as cancer metastasis. Especially for breast, lung and prostate cancer which are originated from soft tissues and prone to metastasis. Thus, the aim of this study is to evaluate the expression level of miR-145-3p which is a shared potential biomarker identified by meta-analysis of breast, prostate and lung cancer data sets. Six different data sets representative of three different cancer types were analyzed. These data sets are pooled together to have a master metamiRNA list while getting rid of the platform differentiations between them. As a result, 24 common differentially expressed miRNAs are determined in which miR-145-3p has the topmost rank. To mimic in vivo cancer microenvironment, hypoxia and serum deprivation were used to induce metastasis in breast (MCF-7, MDA-MB-231, MDA-MB-453), prostate (PC3, LNCaP, DU145), lung (A549, NCIH82,) cancer cell lines and noncancerous cell lines of the coresponding tissues (MCF10A, RWPE-1, MRC-5). miR-145-3p expression levels were determined by qRT-PCR. It has been shown that it is down regulated by the induction of metastasis in cancer cell lines while it is up regulated in normal cell lines to suppress the tumor formation. As a conclusion, as representing the same results in three different cancer cell types, miR-145-3p will be a promising biomarker to follow up its expression to detect cancer metastasis.

Abstract
MicroRNAs (miRNAs) are RNA molecules at about 22 nucleotide in length that are non-coding, which regulate gene expression in the post-transcriptional level by performing degradation or blocks translation of the target mRNA. It is known that they play roles in mechanisms such as metabolic regulation, embryogenesis, organogenesis, differentiation and growth control by providing post-transcriptional regulation of gene expression. With these properties, miRNAs play important roles in the regulation of biological processes such as proliferation, differentiation, apoptosis, drug resistance mechanisms in eukaryotic cells. In addition, there are miRNAs that can be used for cancer therapy. Tumor cells and tumor microenvironment have different miRNA expression profiles. Some miRNAs are known to play a role in the onset and progression of the tumor. miRNAs with oncogenic or tumor suppressive activity specific to different cancer types are still being investigated. This review summarizes the role of miRNAs in tumorigenesis, therapeutic strategies in human cancer and current studies.

Abstract
Most lung cancer deaths are related to metastases, which indicates the necessity of detecting and inhibiting tumor cell dissemination. Here, we aimed to identify miRNAs involved in metastasis of lung adenocarcinoma as prognostic biomarkers and therapeutic targets. To that end, lymph node metastasis-associated miRNAs were identified in The Cancer Genome Atlas lung adenocarcinoma patient cohort (sequencing data; n = 449) and subsequently validated by qRT-PCR in an independent clinical cohort (n = 108). Overexpression of miRNAs located on chromosome 14q32 was associated with metastasis in lung adenocarcinoma patients. Importantly, Kaplan-Meier analysis and log-rank test revealed that higher expression levels of individual 14q32 miRNAs (mir-539, mir-323b, and mir-487a) associated with worse disease-free survival of never-smoker patients. Epigenetic analysis including DNA methylation microarray data and bisulfite sequencing validation demonstrated that the induction of 14q32 cluster correlated with genomic hypomethylation of the 14q32 locus. CRISPR activation technology, applied for the first time to functionally study the increase of clustered miRNA levels in a coordinated manner, showed that simultaneous overexpression of 14q32 miRNAs promoted tumor cell migratory and invasive properties. Analysis of individual miRNAs by mimic transfection further illustrated that miR-323b-3p, miR-487a-3p, and miR-539-5p significantly contributed to the invasive phenotype through the indirect regulation of different target genes. In conclusion, overexpression of 14q32 miRNAs, associated with the respective genomic hypomethylation, promotes metastasis and correlates with poor patient prognosis in lung adenocarcinoma.Implications: This study points to chromosome 14q32 miRNAs as promising targets to inhibit tumor cell dissemination and to predict patient prognosis in lung adenocarcinoma.

[PMID: 29328362 DOI: 10.3892/ijmm.2018.3358] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2016] [Accepted: 12/15/2017] [Indexed: 11/05/2022] Open
Abstract
The aim of the present study was to explore the role of miR‑493-5p in liver cancer tissues and cell lines, and its effect on cell behavioral characteristics. The expression of miR-493-5p was detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) in liver cancer tissues and cell lines (hepatic cell line HL-7702 and the liver cancer cell lines HCCC-9810, HuH-7 and HepG2). In addition, the mechanism by which miR-493-5p mediates its effects was analyzed via the transfection of miR-493-5p mimic and negative control miRNA into HepG2 cells. The viability, proliferation, apoptosis and invasion of the cells were analyzed using MTT assay, flow cytometry and Transwell chamber experiments. Furthermore, the effect of miR-493-5p on the expression of vesicle associated membrane protein 2 (VAMP2) was assayed using a dual-luciferase reporter system, and VAMP2 protein levels were determined by western blot analysis. In addition, following the cotransfection of HepG2 cells with pcDNA3.1‑VAMP2 plasmid and miR‑493-5p mimic, the role of miR-493-5p as a regulator of VAMP2 was evaluated using MTT assay, flow cytometry and Transwell chamber experiments. RT-qPCR analysis indicated that the expression of miR-493-5p in liver cancer tissues and cell lines was decreased significantly compared with that in adjacent normal liver tissues and normal liver cell lines, respectively. Compared with the control group, the cells transfected with miR-493-5p mimic (the miR-493-5p overexpression group) exhibited reduced cell viability, a reduced percentage of cells in the S phase and an increased percentage of apoptotic cells. In addition, fewer cells passed through the Transwell membrane in the miR-493-5p overexpression group compared with the control group. In the dual-luciferase reporter assay, luciferase activity in the miR‑493-5p overexpression group was attenuated compared with that in the control group. In addition, western blot analysis indicated that the VAMP2 protein levels in the miR‑493-5p overexpression group were lower than those in the control group. Furthermore, in cells overexpressing miR-493-5p and VAMP2 simultaneously, the biological behavior of the cells, including cell viability, cell cycle and cell invasiveness, was significantly rescued compared with that of the control group transfected with miR‑493-5p alone. In conclusion, miR-493-5p is indicated to be a tumor suppressor gene, and is downregulated in human liver cancer. miR-493-5p overexpression promotes cell apoptosis and inhibits the proliferation and migration of liver cancer cells by negatively regulating the expression of VAMP. These observations suggest the potential of treating liver cancer by the overexpression of microRNA-493-5p.

Abstract
Altered microRNA expression has been found to be a common feature of several cancers, including lung carcinomas. However, the possible roles of miR-768-3p in the pathological changes of lung carcinomas are still unknown. The aim of the present study was to investigate the expression and possible effects of miR-768-3p in human non-small cell lung carcinomas (NSCLC). Eighty-three NSCLC patients attending the clinic of Kunming Hospital were invited to participate in the study. Their tumor samples were obtained for qRT-PCR analysis. Human NSCLC cell lines, A549 and HCC4006, were employed and transfected with either miR-768-3p mimics or miR-768-3p antagomir. Following transfection, the in vitro and in vivo proliferation, apoptosis fractions, migration and invasion of NSCLC cells were evaluated. The data revealed that: i) upregulated miR-768-3p in tumors were associated with the clinicopathological features of NSCLC patients; ii) inhibiting miR-768-3p function by miR-768-3p antagomir induced distinctly apoptosis and Fas/FasL expressional alteration of NSCLC cells; iii) miR-768-3p antagomir transduction also decreased the viability, migration and invasion, as well as MMP-2 and MMP-9 activities in A549 and HCC4006 cells; and iv) miR-768-3p antagomir transfection also inhibited the growth and proliferation of NSCLC xenografts in nude mice. The present results suggested that abnormal elevated miR-768-3p in NSCLC tumors and cell lines played important roles in NSCLC carcinogenic progression, and the targeting of miR-768-3p might be a potential therapeutic strategy for the treatment of NSCLC.

Abstract
BACKGROUND Studies on the accuracy of microRNAs (miRNAs) in diagnosing non-small cell lung cancer (NSCLC) have still controversial. Therefore, we conduct to systematically identify miRNAs related to NSCLC, and their target genes expression changes using microarray data sets. METHODS We screened out five miRNAs and six genes microarray data sets that contained miRNAs and genes expression in NSCLC from Gene Expression Omnibus. RESULTS Our analysis results indicated that fourteen miRNAs were significantly dysregulated in NSCLC. Five of them were up-regulated (miR-9, miR-708, miR-296-3p, miR-892b, miR-140-5P) while nine were down-regulated (miR-584, miR-218, miR-30b, miR-522, miR486-5P, miR-34c-3p, miR-34b, miR-516b, miR-592). The integrating diagnosis sensitivity (SE) and specificity (SP) were 82.6% and 89.9%, respectively. We also found that 4 target genes (p < 0.05, fold change > 2.0) were significant correlation with the 14 discovered miRNAs, and the classifiers we built from one training set predicted the validation set with higher accuracy (SE = 0.987, SP = 0.824). CONCLUSIONS Our results demonstrate that integrating miRNAs and target genes are valuable for identifying promising biomarkers, and provided a new insight on underlying mechanism of NSCLC. Further, our well-designed validation studies surely warrant the investigation of the role of target genes related to these 14 miRNAs in the prediction and development of NSCLC.

Abstract
Lung cancer is the leading cause of cancer deaths worldwide; the study of microRNAs gives new hope for lung cancer treatment. miR-411 has been demonstrated to be an independent prognostic factor for lung adenocarcinoma, but the role and regulatory mechanism are largely unknown. In the present study, we found miR-411 was overexpressed in the lung cancer cells; overexpression of miR-411 promoted anchorage-dependent and anchorage-independent growths of lung cancer, while miR-411 knockdown reduced this effect. Further study showed forkhead box O1 (FOXO1) was a target of miR-411. Overexpression of miR-411 suppressed the expression of FOXO1; the effect of suppression was abrogated when the mutation occurred in the 3'UTR of FOXO1. Knockdown of FOXO1 in cells which miR-411 was inhibited recapitulated the phenotype of miR-411 overexpression. Taken together, our study revealed miR-411 promoted cell proliferation of lung cancer by targeting tumor suppressor gene FOXO1 and miR-411 might be a potential target for lung cancer therapy.

Abstract
MicroRNAs (miRNAs) play an important role in the development and progression of non-small cell lung cancer (NSCLC). Recently, several studies have shown that miR-99a is downregulated in various cancers, which can affect tumor initiation and maintenance. Herein, we found that miR-99a was downregulated in NSCLC tissues and suppressed tumor metastasis of NSCLC cells. Down-regulation of miR-99a is significantly associated with last-stage and tumor metastasis in NSCLC patients. Further functional experiments found that overexpression of miR-99a inhibit cell proliferation, migration, and invasion of NSCLC cells in vitro and tumor metastasis of NSCLC in vivo. In addition, we also found that AKT1 is directly involved in miR-99a-mediated tumor suppression. Restored the expression of AKT1 partially abolished the suppressive effects miR-99a on proliferation and invasion of NSCLC cells. Collectively, our data suggest that miR-99a plays an important role in the tumorigenesis and metastasis of NSCLC and may serve as a therapeutic target to avoid dissemination of NSCLC cells.

Abstract
MicroRNAs play important roles in carcinogenesis and tumor progress. Lung cancer is the leading cause of cancer mortality worldwide. In this study, the function of miR-181a-5p was investigated in non-small-cell lung cancer (NSCLC). Results showed that miR-181a-5p was significantly decreased in NSCLC tissues and cell lines. The proliferation and migration of A549 cells transfected with miR-181a-5p mimic was significantly inhibited. Luciferase activity assay results demonstrated that two binding sites of Kras could be directly targeted by miR-181a-5p. Furthermore, Kras was down-regulated by miR-181a-5p at both transcriptional and translational levels. SiRNA-mediated Kras down-regulation could mimic the effects of miR-181a-5p mimic in A549 cells. Our findings suggest that miR-181a-5p plays a potential role in tumor suppression by partially targeting Kras and has the potential therapeutic application in NSCLC patients.

MiR-205 and miR-218 expression is associated with carboplatin chemoresistance and regulation of apoptosis via Mcl-1 and Survivin in lung cancer cells. Cell Signal 2015; 27:1576-88.

Abstract
Lung cancer chemoresistance is the most frequent barrier in lung cancer therapy. Recent studies have indicated that microRNAs play a significant role in this mechanism and can function as either tumor suppressor or tumor promoters. However the effect of miRNA in lung cancer chemoresistance is poorly understood. Therefore, in the present study we investigated the role of two distinct miR members, the miR-205 and the tumor suppressor miR-218 in the proliferation, invasion and induction of apoptosis in lung cancer cells after carboplatin treatment. The results showed that miR-205 overexpression in A549 and H1975 lung cancer cells is concurrent with the down regulation of miR-218 and in linked with carboplatin sensitivity and chemoresistance. Interestingly, ectopic miR-218 overexpression reduced cell proliferation, invasion and migration of lung cancer cells, whereas miR-205 rescued the suppressive effect of miR-218 by altering the expression levels of the pro-apoptotic proteins PARP, Caspase 3, Bax and upregulating the anti-apoptotic markers Mcl-1 and Survivin. Taken together our findings imply that the miRNAs miR-205 and miR-218 play a key role in the development of lung cancer acquired chemoresistance and the tumor suppressor role of miR-218 in inhibiting lung cancer cell tumorigenesis and overcoming platinum chemoresistance is significant for future cancer therapeutic approaches.

BMC Clin Pathol 2014; 14:45. [PMID: 25525410 PMCID: PMC4269969 DOI: 10.1186/1472-6890-14-45] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2014] [Accepted: 12/03/2014] [Indexed: 12/26/2022] Open
Abstract
Background Dicer and Drosha are important enzymes for processing microRNAs. Recent studies have exhibited possible links between expression of different miRNAs, levels of miRNA processing enzymes, and cancer prognosis. We have investigated the prognostic impact of Dicer and Drosha and their correlation with miR-126 expression in a large cohort of non-small cell lung cancer (NSCLC) patients. We aimed to find patient groups within the cohort that might have an advantage of receiving adjunctive therapies. Methods Dicer expression in the cytoplasm and Drosha expression in the nucleus were evaluated by manual immunohistochemistry of tissue microarrays (TMAs), including tumor tissue samples from 335 patients with resected stages I to IIIA NSCLC. In addition, in situ hybridizations of TMAs for visualization of miR-126 were performed. Kaplan–Meier analysis was performed, and the log-rank test via SPSS v.22 was used for estimating significance levels. Results In patients with normal performance status (ECOG = 0, n = 197), high Dicer expression entailed a significantly better prognosis than low Dicer expression (P = 0.024). Dicer had no significant prognostic value in patients with reduced performance status (ECOG = 1–2, n = 138). High Drosha expression was significantly correlated with high levels of the microRNA 126 (miR-126) (P = 0.004). Drosha/miR-126 co-expression had a significant negative impact on the disease-specific survival (DSS) rate (P < 0.001). Multivariate analyses revealed that the interaction Dicer*Histology (P = 0.049) and Drosha/miR-126 co-expression (P = 0.033) were independent prognostic factors. Conclusions In NSCLC patients with normal performance status, Dicer is a positive prognostic factor. The importance of Drosha as a prognostic factor in our material seems to be related to miR-126 and possibly other microRNAs.

Abstract
Lung cancer is a leading cause of cancer deaths worldwide. Although the molecular pathways of lung cancer have been partly known, the high mortality rate is not markedly changed. MicroRNAs (miRNAs) are small noncoding RNAs that actively modulate cell physiological processes as apoptosis, cell-cycle control, cell proliferation, DNA repair, and metabolism. Several studies demonstrated that miRNAs are involved in the pathogenesis of lung diseases including lung cancer and they negatively regulate gene and protein expression by acting as oncogenes or tumor suppressors. In this review we summarize the current knowledge on the role of miRNAs and their target genes in lung tumorigenesis and evaluate their potential use as therapeutic agents in lung cancer. In particular, we describe methodological approaches such as inhibition of oncogenic miRNAs or replacement of tumor suppressor miRNAs, both in in vitro and in vivo assays. Furthermore we discuss new strategies to achieve in vivo tissue specific delivery, potential off-target effects, and safety of miRNAs systemic delivery.

[PMID: 24631464 DOI: 10.1016/j.arr.2014.02.009] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2013] [Revised: 02/28/2014] [Accepted: 02/28/2014] [Indexed: 02/07/2023]
Abstract
Lung cancer is a leading cause of cancer deaths worldwide. Development of lung cancer is associated with exposure to carcinogens such as tobacco smoke and some environmental factors. The incidence of lung cancer increases with age, particularly after age 60. It was estimated that less than 2% of all lung cancer cases occurred in patients younger than 45; therefore, this type of tumor can be considered as an aging-related disease. MicroRNAs (miRNAs) are small non-coding RNA molecules capable of regulating expression of over 50% of protein-coding genes. miRNAs were shown to play an extremely important role in cell functioning, affecting all biological processes, as well as development of various diseases. Expression profiles of miRNAs are known to be altered in cancer, including lung cancer, and also exhibit changes during aging. These RNA molecules are stable in tissue sections and blood and reflect tumor origin, histotype, and stage, which make them candidate diagnostic and prognostic biomarkers. miRNA mimetics or inhibitors can be delivered into a cell, with possible therapeutic implications. Here, we review the results obtained during the last several years that demonstrate the aging-related regulation of miRNAs expression, in association with their role in lung cancer initiation, progression, and resistance to anticancer therapy, as well as the possibility to use miRNAs as predictive biomarkers for treatment response.

[PMID: 24375253 DOI: 10.1007/s13277-013-1551-z] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2013] [Accepted: 12/13/2013] [Indexed: 12/14/2022] Open
Abstract
The objectives of this study were to detect the expressions of microRNA-218 (miR-218) in human gastrointestinal stromal tumor (GIST) tissues and cells and explore its effects on the biological features of GIST-T1 cells and the expression of its target gene KIT, so as to provide new insights for GIST treatment. Using quantitative real-time polymerase chain reaction (qRT-PCR), we detected the expressions of miR-218 in the tissues and adjacent tissues of GIST and in the GIST cell lines including GIST882, GIST430, GIST48, and GIST-T1. Forty-eight hours after the miR-218 mimic was transfected into the GIST-T1 cells, the expression of miR-218 in the GIST-T1 cells was detected by qRT-PCR. The effect of miR-218 on the GIST-T1 cell viability was detected using MTT. The effect of miR-218 on the proliferation and apoptosis of GIST-T1 cell was analyzed using flow cytometry. Transwell invasion chamber was applied to detect the effect of miR-218 on the invasion of GIST-T1 cells. KIT was identified to be a target gene of miR-218 by the luciferase reporter enzyme system, and the effect of miR-218 on the expression of KIT protein in cells was determined using Western blotting. As shown by qRT-PCR, compared with that in the GIST adjacent tissue, the expressions of miR-218 in the tumor tissue and GIST cell lines were significantly decreased (P < 0.0001). Compared with the control group, the expression of miR-218 increased significantly in GIST-T1 cells transfected with miR-218 mimic for 48 h (P < 0.01). MTT showed that the cell viability decreased significantly after the overexpression of miR-218 in the GIST-T1 cells (P < 0.01). Flow cytometry showed that the cell proliferation index significantly declined after the overexpression of miR-218 (P < 0.01); meanwhile, the apoptosis of cells also significantly increased (P < 0.01). Detection using the Transwell invasion chamber showed that the number of cells passing through the Transwell chamber significantly dropped after the enhanced expression of miR-218 (P < 0.01). Luciferase reporter gene assay showed that, compared with the control group, the relative luciferase activity significantly declined in the miR-218 mimic transfection group (P < 0.01). Compared with the control group, the expression of KIT protein in the GIST-T1 cells transfected with miR-218 mimic for 48 h significantly decreased (P < 0.01). In conclusion, the expression of miR-218 decreases in human GIST tissue and cell lines. miR-218 can negatively regulate the expression of KIT protein and inhibit the proliferation and invasion of GIST cells. Treatment based on the enhanced expression of miR-218 may be a promising strategy for GIST.

Abstract
Human lung cancer is the leading cause of cancer motility worldwide, with nearly 1.4 million deaths each year, among which non-small cell lung cancer (NSCLC) accounts for almost 85% of this disease. The discovery of microRNAs (miRNAs) provides a new avenue for NSCLC diagnostic and treatment regiments. Currently, a large number of miRNAs have been reported to be associated with the progression of NSCLC, among which serum miR-137 has been examined to be down-regulated in NSCLC patients. However, the function of miR-137 on NSCLC cells migration and invasion and the relative mechanisms were less known. Here, we found that ectopic expression of miR-137 could inhibit cell proliferation, induce cell apoptosis, and suppress cell migration and invasion in NSCLC cell line A549. Moreover, we found that paxillin (PXN) was a target gene of miR-137 in NSCLC cells and restored expression of PXN abolished the miR-137-mediated suppression of cell migration and invasion. Taken together, our results showed that miR-137 acted as a tumor suppressor in NSCLC by targeting PXN, and it may provide novel diagnostic and therapeutic options for human NSCLC clinical operation in future.
