System biology approach to identify the novel biomarkers in glioblastoma multiforme tumors by using computational analysis. Front Pharmacol 2024; 15:1364138. [PMID: 38841373 PMCID: PMC11150670 DOI: 10.3389/fphar.2024.1364138] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Accepted: 04/22/2024] [Indexed: 06/07/2024] Open
Abstract
Introduction: The most common primary brain tumor in adults is glioblastoma multiforme (GBM), accounting for 45.2% of all cases. The characteristics of GBM, a highly aggressive brain tumor, include rapid cell division and a propensity for necrosis. Regretfully, the prognosis is extremely poor, with only 5.5% of patients surviving after diagnosis. Methodology: To eradicate these kinds of complicated diseases, significant focus is placed on developing more effective drugs and pinpointing precise pharmacological targets. Finding appropriate biomarkers for drug discovery entails considering a variety of factors, including illness states, gene expression levels, and interactions between proteins. Using statistical techniques like p-values and false discovery rates, we identified differentially expressed genes (DEGs) as the first step in our research for identifying promising biomarkers in GBM. Of the 132 genes, 13 showed upregulation, and only 29 showed unique downregulation. No statistically significant changes in the expression of the remaining genes were observed. Results: Matrix metallopeptidase 9 (MMP9) had the greatest degree in the hub biomarker gene identification, followed by (periostin (POSTN) at 11 and Hes family BHLH transcription factor 5 (HES5) at 9. The significance of the identification of each hub biomarker gene in the initiation and advancement of glioblastoma multiforme was brought to light by the survival analysis. Many of these genes participate in signaling networks and function in extracellular areas, as demonstrated by the enrichment analysis.We also identified the transcription factors and kinases that control proteins in the proteinprotein interactions (PPIs) of the DEGs. Discussion: We discovered drugs connected to every hub biomarker. It is an appealing therapeutic target for inhibiting MMP9 involved in GBM. Molecular docking investigations indicated that the chosen complexes (carmustine, lomustine, marimastat, and temozolomide) had high binding affinities of -6.3, -7.4, -7.7, and -8.7 kcal/mol, respectively, the mean root-mean-square deviation (RMSD) value for the carmustine complex and marimastat complex was 4.2 Å and 4.9 Å, respectively, and the lomustine and temozolomide complex system showed an average RMSD of 1.2 Å and 1.6 Å, respectively. Additionally, high stability in root-mean-square fluctuation (RMSF) analysis was observed with no structural conformational changes among the atomic molecules. Thus, these in silico investigations develop a new way for experimentalists to target lethal diseases in future.

J Egypt Natl Canc Inst 2024; 36:16. [PMID: 38679648 DOI: 10.1186/s43046-024-00220-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 04/06/2024] [Indexed: 05/01/2024] Open
Abstract
BACKGROUND MicroRNAs (miRNAs or miRs) are highly conserved non-coding RNAs with a short length (18-24 nucleotides) that directly bind to a complementary sequence within 3'-untranslated regions of their target mRNAs and regulate gene expression, post-transcriptionally. They play crucial roles in diverse biological processes, including cell proliferation, apoptosis, and differentiation. In the context of cancer, miRNAs are key regulators of growth, angiogenesis, metastasis, and drug resistance. MAIN BODY This review primarily focuses on miR-939 and its expanding roles and target genes in cancer pathogenesis. It compiles findings from various investigations. MiRNAs, due to their dysregulated expression in tumor environments, hold potential as cancer biomarkers. Several studies have highlighted the dysregulation of miR-939 expression in human cancers. CONCLUSION Our study highlights the potential of miR-939 as a valuable target in cancer diagnosis, prognosis, and treatment. The aberrant expression of miR-939, along with other miRNAs, underscores their significance in advancing our understanding of cancer biology and their promise in personalized cancer care.

[PMID: 35518349 PMCID: PMC9064538 DOI: 10.1155/2022/3439656] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 03/25/2022] [Accepted: 04/05/2022] [Indexed: 11/17/2022]
Abstract
OBJECTIVE To develop a putative microRNA (miRNA) and messenger RNA (mRNA) regulatory network of Danggui Buxue decoction's (DGBXD) amelioration of idiopathic pulmonary fibrosis (IPF). METHODS The Gene Expression Omnibus (GEO) database was used to identify differentially expressed miRNAs (DE-miRNAs) and differentially expressed mRNAs (DE-mRNAs). Using miRNet, the predicted target genes of identified DE-miRNAs were estimated, and then the target genes of DE-miRNAs in IPF were comprehensively examined. The Enrichr database was used to conduct functional enrichment and pathway enrichment. Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) was employed to obtain the target genes of DGBXD as well as active compounds. A putative miRNA-mRNA regulatory network of DGBXD acting on IPF was developed by intersecting the target genes of DGBXD with the DE-miRNA target genes in IPF. A bleomycin-induced mouse model was established and used to perform histopathology as well as real-time quantitative polymerase chain reaction (qRT-PCR) analyses of some miRNA-mRNA pairs. RESULTS Fourteen upmodulated DE-miRNAs and six downmodulated DE-miRNAs were screened. The downstream target genes of upmodulated and downmodulated DE-miRNAs were predicted. Subsequently, 1160 upmodulated DE-mRNAs and 1427 downmodulated DE-mRNAs were identified. Then, target genes of DE-miRNAs comprising 49 downmodulated and 53 upmodulated target genes were further screened to perform functional enrichment and pathway enrichment analyses. Subsequently, 196 target genes of DGBXD were obtained from TCMSP, with six downregulated target genes and six upregulated target genes of DGBXD acting on IPF being identified. A promising miRNA-mRNA regulatory network of DGBXD acting on IPF was developed in this study. Moreover, mir-493 together with its target gene Olr1 and mir-338 together with Hif1a were further validated by qRT-PCR. CONCLUSION This study proposed detailed possible processes of miRNA-mRNA modulatory axis in IPF and constructed a prospective IPF-related miRNA-mRNA modulatory network with the aim of alleviating IPF with DGBXD.

Abstract
Biomarkers predictive of drug-specific outcomes are important tools for personalized medicine. In this study, we present an integrative analysis to identify miRNAs that are predictive of drug-specific survival outcome in cancer. Using the clinical data from TCGA, we defined subsets of cancer patients who suffered from the same cancer and received the same drug treatment, which we call cancer-drug groups. We then used the miRNA expression data in TCGA to evaluate each miRNA’s ability to predict the survival outcome of patients in each cancer-drug group. As a result, the identified miRNAs are predictive of survival outcomes in a cancer-specific and drug-specific manner. Notably, most of the drug-specific miRNA survival markers and their target genes showed consistency in terms of correlations in their expression and their correlations with survival. Some of the identified miRNAs were supported by published literature in contexts of various cancers. We explored several additional breast cancer datasets that provided miRNA expression and survival data, and showed that our drug-specific miRNA survival markers for breast cancer were able to effectively stratify the prognosis of patients in those additional datasets. Together, this analysis revealed drug-specific miRNA markers for cancer survival, which can be promising tools toward personalized medicine.

Abstract
Non-small cell lung cancer (NSCLC) is a common histological subtype of lung cancer, which occupies 80-85% of the proportion in all lung cancer cases. Therefore, this study was designed to clarify the role and underlying molecular mechanisms of circFAM126A in NSCLC. The real-time quantitative polymerase chain reaction (RT-qPCR) assay was conducted to assess circFAM126A, FAM126A, miR-613, and IRS2 expression in NSCLC tissues and cells. The proliferation ability of cells was measured by MTT, EdU, and colony-forming assays. The flow cytometry assay was performed to evaluate cell cycle distribution and apoptosis of NSCLC cells. The migration and invasion were determined by wound healing and transwell matrigel assays, respectively. The interaction relationship between miR-613 and circFAM126A or IRS2 was analyzed by dual-luciferase reporter and RNA pull-down assays. Tumorigenesis in nude mice was conducted to clarify the functional roles of circFAM126A inhibition in vivo. CircFAM126A was obviously overexpressed in NSCLC tissues and cells when compared with controls. The loss-of-functional experiments suggested that knockdown of circFAM126A suppressed proliferation, migration and invasion, as well as caused apoptosis and cell cycle arrest in NSCLC cells, which was abolished by silencing of miR-613. In addition, IRS2 was a target gene of miR-613. Overexpression of miR-613 exerted carcinoma inhibitor role in NSCLC by inhibition of IRS2 expression. Consistently, the silencing of circFAM126A also functioned anti-tumorigenic roles in nude mice in vivo. Mechanistically, circFAM126A could function as a miRNA sponge for miR-613 to regulate the expression of IRS2, thereby regulating proliferation, migration, invasion, apoptosis, and cell cycle arrest in NSCLC cells.

[PMID: 35007826 DOI: 10.1016/j.tice.2021.101720] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Revised: 11/25/2021] [Accepted: 12/22/2021] [Indexed: 02/07/2023]
Abstract
OBJECTIVES Osteosarcoma is a relatively common primary malignant bone tumor in clinic, which frequently occurs in children and adolescents. It is essential to clarify the molecular mechanism of osteosarcoma to provide better diagnosis and treatment. Abnormal expression of miRNAs is closely related to the pathogenesis and progression of osteosarcoma. MiRNAs play a regulatory role in tumorigenesis and development of osteosarcoma. The purpose of this study is to reveal the working mechanism of miR-139/ITGAV axis in osteosarcoma progression. METHODS ITGAV and miR-139 expression was detected in osteosarcoma tissues or paracancerous normal tissues. TargetScan and Double luciferase reporter gene assay were adopted to verify weather ITGAV was the target gene of miR-139. Western blot and qRT-PCR were used to evaluate the effects of miR-139 on ITGAV. CCK8, Flow cytometry, Transwell and Cell wound scratch assay were used to measure the effects of miR-139 and ITGAV on cell cycle, proliferation, migration and invasion of MG63, respectively. A nude mouse xenograft model of cervical cancer was constructed to observe the effects of miR-139 on the tumor growth. RESULTS We found that the expression of miR-139 in osteosarcoma tissue was significantly reduced, while the expression of ITGAV was significantly increased. MiR-139 could specifically bind to the 3'-UTR of ITGAV and negatively regulate its expression. Transfection of miR-139 mimic could inhibit the proliferation, S-phase arrest, invasion and migration of MG63 cells, and up-regulating the expression of ITGAV could reverse such inhibitory effect. In nude mouse xenograft model of osteosarcoma, overexpression of miR-139 could inhibit tumor growth, while down-regulation of miR-139 produced the opposite effect. CONCLUSIONS These results indicate that miR-139/ITGAV axis was related to osteosarcoma initiation. MiR-139 could inhibit the biological behavior of osteosarcoma cells and the tumor growth in nude mouse model via targeting ITGAV, and miR-139/ITGAV axis may impede the progression of osteosarcoma.

Abstract
Background Non-small-cell lung cancer (NSCLC) is the commonest type of lung cancer, which is one of most deadly cancers that possess high morbidity and mortality all over the world. The function of circular RNA NIMA related kinase 6 (circ_NEK6) in NSCLC is still unknown. Therefore, circ_NEK6 is worth studying in detail. Methods RT-qPCR and western blot assays were employed to detect gene expression. Colony formation, EdU, JC-1, flow cytometry, and Transwell assays were implemented to explore the function of circ_NEK6 on biological activities of NSCLC cells. Mechanism experiments were conducted to unveil the relationship among molecules. Results Circ_NEK6 expression was highly expressed in NSCLC tissues and cells. Functionally, the silencing of circ_NEK6 could effectively suppress NSCLC cell proliferation, migration and invasion. Circ_NEK6 sequestered miR-382-5p to fortify the expression of breast carcinoma amplified sequence 2 (BCAS2) in NSCLC. Besides, BCAS2 had tumor-promoting function in NSCLC. Furthermore, the effects of down-regulated circ_NEK6 on the malignant behaviors of NSCLC cells were totally recovered by miR-382-5p inhibition or BCAS2 overexpression. Conclusions Circ_NEK6 served as a competing endogenous RNA (ceRNA) of BCAS2 by absorbing miR-382-5p, which may be treated as a novel promising target for the treatment of NSCLC.

Abstract
The aim of the present study was to investigate the effect of hedgehog‑interacting protein antisense RNA 1 (HHIP‑AS1) on epithelial‑mesenchymal transition (EMT) and cellular stemness of human lung cancer cells by regulating the microRNA (miR)‑153‑3p/PCDHGA9 axis. Reverse transcription‑quantitative PCR was used to compare the expression of HHIP‑AS1 in lung cancer and adjacent normal lung tissues. In addition, the correlation of HHIP‑AS1 with E‑cadherin, Vimentin, N‑cadherin and Twist1 was analyzed. HHIP‑AS1 overexpression vector was transfected into lung cancer A549 and NCI‑H1299 cell lines. Cell Counting Kit‑8 and Transwell and clonogenic assays were used to detect the proliferation, invasion and clonogenesis of the lung cancer cells, respectively. The associations among HHIP‑AS1, miR‑153‑3p and PCDHGA9 were predicted by bioinformatics analysis and verified by a dual‑luciferase reporter system. The results showed that the expression of HHIP‑AS1 in lung cancer tissues was significantly lower than that in normal tissues (P<0.001). HHIP‑AS1 was positively correlated with E‑cadherin and negatively correlated with Vimentin, N‑cadherin and Twist1. HHIP‑AS1 overexpression inhibited the proliferation, invasion and clonal formation of the A549 and NCI‑H1299 cells. The luciferase reporter system verified that HHIP‑AS1 could adsorb miR‑153‑3p and that PCDHGA9 was the target gene of miR‑153‑3p. A549 cells were transfected with HHIP‑AS1 overexpression vector and miR‑153‑3p mimic, and the miR‑153‑3p mimic had a mitigating effect on HHIP‑AS1 inhibition (P<0.001). In conclusion, HHIP‑AS1 inhibits the EMT and stemness of lung cancer cells by regulating the miR‑153‑3p/PCDHGA9 axis. Thus, HHIP‑AS1 may be a new potential target for lung cancer treatment.

Abstract
Previous studies have reported that the aberrant expression of circulating microRNAs (miRNAs/miRs) can be used as diagnostic and prognostic markers in non-small cell lung cancer (NSCLC). The present study aimed to assess the diagnostic and prognostic predictive values of four plasma miRNAs for NSCLC. A total of 12 candidate miRNAs were selected that have previously been reported to be aberrantly expressed in NSCLC, and their plasma levels in the training set were detected via reverse transcription-quantitative PCR analysis. The screened out miRNAs were further validated in the testing set. The area under the curve (AUC) of the receiver operating characteristic curve was constructed to evaluate diagnostic performance. Kaplan-Meier survival analysis was performed to assess the association between the plasma miRNA levels and disease-free survival (DFS) time. The results demonstrated that 4/12 plasma miRNAs (miR-210, miR-1290, miR-150 and miR-21-5p) were highly expressed in patients with NSCLC compared with their expression levels in patients with benign lung disease (BLD) and healthy controls in the training and testing sets, respectively. The AUC values of the four-miRNA panel were 0.96 and 0.93 in the training and testing sets, respectively, for distinguishing patients with NSCLC from healthy controls, which were similar to the AUC values for distinguishing patients with NSCLC from patients with BLD (0.96 and 0.94). The AUC values of the four-miRNA panel in patients with stage I NSCLC were comparable to that of patients with stage II-III NSCLC (0.942 and 0.965). Patients with high plasma levels of miR-210 and miR-150 had worse DFS than those with low plasma levels of these miRNAs. In addition, patients whose plasma levels of the four miRNAs decreased by >50% after surgery exhibited a good DFS. Taken together, the results of the present study suggest that these four miRNAs (miR-210, miR-1290, miR-150 and miR-21-5p) act as useful biomarkers for early diagnosis and prognosis of NSCLC.

Abstract
Lung cancer is the most prevalent cancer worldwide, with its mortality rate reported to be in millions annually; one of the two subtypes is non-small cell lung cancer (NSCLC). In this study, we investigated the interactions and expressions of zinc finger E-box binding homeobox 1 (ZEB1), microRNA-320a (miR-320a) and RAD51-associated protein 1 (RAD51AP1) in NSCLC tissues to determine the roles of ZEB1 in regulation of miR-320a and RAD51AP1 in the development and metastasis of NSCLC. First, the expression levels of miR-320a and ZEB1 were quantified in NSCLC tissues and cells. Transfection assay was conducted to identify the effects of miR-320a on the progression of NSCLC cells. The interaction of miR-320a with ZEB1 and RAD51AP1 was predicted and verified using dual-luciferase reporter gene assay and chromatin immunoprecipitation assay. Finally, subcutaneous xenograft tumors of 6-week mice and metastatic model tumors of 8-week mice were established to further explore the in vivo effect of miR-320a/ZEB1/RAD51AP1 on NSCLC. The findings revealed a lower expression of miR-320a in NSCLC tissues and cells, while this result was reversed regarding ZEB1 expression. ZEB1 suppressed miR-320a expression and upregulation of miR-320a resulted in the reduction of proliferation, invasion and metastasis rate of NSCLC cells, and promoted NSCLC cell apoptosis. ZEB1 promoted the expression of RAD51AP1 via inhibition of miR-320a, promoting tumor growth in vivo. ZEB1 transcriptionally inhibited the expression of miR-320a and upregulated the expression of RAD51AP1, thereby promoting metastasis in NSCLC.

FASEB J 2021; 35:e21571. [PMID: 33861889 DOI: 10.1096/fj.202002694r] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 03/08/2021] [Accepted: 03/19/2021] [Indexed: 12/21/2022]
Abstract
Liver fibrosis is a common feature of liver dysfunction during chronic liver diseases and is frequently associated with angiogenesis, a dynamic process that forms new blood vessels from preexisting vasculature. MicroRNAs (miRNAs), which act as posttranscriptional regulators of gene expression, have been shown to regulate liver fibrosis; however, how miRNAs regulate angiogenesis and its mechanism in fibrosis are not well understood. We aimed to elucidate the role and mechanism of miR-30c in attenuating liver fibrosis. Using miRNA profiling of fibrotic murine livers, we identified differentially regulated miRNAs and discovered that miR-30c is aberrantly expressed and targets endothelial delta-like ligand 4 (DLL4) in either carbon tetrachloride-treated or bile duct ligated fibrotic mice, as well as in patients with liver fibrosis. Using CCK-8, wound healing and Matrigel tube formation assays, we found that miR-30c inhibited liver sinusoidal endothelial cell (LSEC) proliferation, migration, and angiogenesis capacity by targeting DLL4 in vitro. Importantly, nanoparticle-based delivery of miR-30c to LSECs inhibited the DLL4/Notch pathway and angiogenesis, thereby ameliorating liver fibrosis in vivo. Collectively, our findings demonstrate a protective role of miR-30c in liver fibrosis by regulating DLL4/Notch signaling and angiogenesis. Thus, miR-30c may serve as a potential treatment for chronic liver diseases.

Analysis of the microRNA and mRNA expression profile of ricin toxin-treated RAW264.7 cells reveals that miR-155-3p suppresses cell inflammation by targeting GAB2. Toxicol Lett 2021; 347:67-77. [PMID: 33865919 DOI: 10.1016/j.toxlet.2021.04.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 03/24/2021] [Accepted: 04/12/2021] [Indexed: 02/06/2023]
Abstract
Ricin toxin (RT) is one of the most lethal toxins derived from the seed of castor beans. In addition to its main toxic mechanism of inhibiting the synthesis of cellular proteins, RT can induce the production of inflammatory cytokines. MicroRNAs (miRNAs) play a key role in regulating both innate and adaptive immunity. To elucidate the regulation of miRNAs in RT-induced inflammation injury, the RNA high-throughput sequencing (RNA-Seq) technology was used to analyze the expression profile of miRNAs and mRNAs in RT-treated RAW264.7 cells. Results showed that a total of 323 mRNAs and 19 miRNAs differentially expressed after RT treated. Meanwhile, 713 miRNA-mRNA interaction pairs were identified by bioinformatics analysis. KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway analysis showed that those interaction pairs were mainly involved in JAK-STAT, T cell receptor, and MAPK signaling pathways. Moreover, we further predicted and determined the targeting relationship between miR-155-3p and GAB2 through TargetScan and dual-luciferase reporter assay. Mechanically, overexpression of miR-155-3p can reduce the secretion of TNF-α in RAW264.7 cells, revealing a possible mechanism of miR-155-3p regulating RT-induced inflammatory injury. This study provides a new perspective for clarifying the mechanism of RT-induced inflammatory injury and reveals the potential role of miRNAs in innate immune regulation.

Abstract
The aim of the study was a search for diagnostic and/or prognostic biomarkers in patients with non-small cell lung cancer (NSCLC) patients, based on circulating microRNAs (miRs: miR-23a, miR-361, miR-1228 and miR-let7i) in extracellular vesicles (EVs). Serum EVs were isolated from NSCLC patients (n = 31) and control subjects (n = 21). RNA was isolated from EVs and reverse transcription reaction was performed. Relative levels of miR-23a, miR-361, miR-1228 and miR-let7i were assessed in real-time qPCR using TaqMan probes. Analysis was based on the 2-ΔΔCT method. Statistically significant lower levels of miR-23a and miR-let7i were observed among NSCLC patients vs. control group: miR-23a, 0.054 vs. 0.107; miR-let7i, 0.193 vs. 0.369 (p = 0.003, p = 0.005, respectively). A receiver operating characteristic (ROC) curve analysis demonstrated the diagnostic potential of each individual serum EV-derived miRNA with an area under the curve AUC = 0.744 for miR-23a (p = 0.0003), 0.733 for miR-let7i (p = 0.0007). The decreased level of miR-23a in patients correlated with metastasis to lymph nodes and with AJCC tumor staging system. The results demonstrate that miR-23a and miR-let7i may prove clinically useful as significant, non-invasive markers in NSCLC diagnosis. Additionally, changing profile level of miR-23a that correlates with cancer development may be considered as an NSCLC progression marker.

J Hepatol 2020; 73:603-615. [PMID: 32593682 DOI: 10.1016/j.jhep.2020.03.050] [Citation(s) in RCA: 51] [Impact Index Per Article: 12.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2019] [Revised: 03/19/2020] [Accepted: 03/20/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND & AIMS Obesity is an independent risk factor for malignancies, including hepatocellular carcinoma (HCC). However, it remains unknown whether maternal obesity affects the incidence of HCC in offspring. Thus, we aimed to investigate this association and its underlying mechanisms. METHODS Diethylnitrosamine (DEN) was used to induce HCC in a high-fat diet (HFD)-induced multigenerational obesity model. RNA-sequencing was performed to identify the genes and microRNAs (miRNAs) that were altered over generations. The role of the miR-27a-3p-Acsl1/Aldh2 axis in HCC was evaluated in cell lines and HCC-bearing nude mice, and its intergenerational impact was studied in pregnant mice and their offspring. RESULTS Under HFD stress, maternal obesity caused susceptibility of offspring to DEN-induced HCC, and such susceptibility was cumulative over generations. We identified that Acsl1 and Aldh2, direct targets of miR-27a-3p, were gradually changed over generations. Under hyperlipidemic conditions, downregulation of Acsl1 and Aldh2 increased cell proliferation (in vitro) or tumor growth (in vivo) in synergy. Intratumor injection of an miR-27a-3p agomir exacerbated tumor growth by downregulating Acsl1 and Aldh2; while intratumor injection of an miR-27a-3p antagomir had the opposite effect. Moreover, serum miR-27a-3p levels gradually increased in the HFD-fed maternal lineage over generations. Injecting pregnant mice with an miR-27a-3p agomir not only upregulated hepatic miR-27a-3p and downregulated Acsl1/Aldh2 in offspring (fetus, young and adult stages), but also exacerbated HCC development in DEN-treated offspring. In human HCC, upregulated miR-27a-3p and downregulated Acsl1/Aldh2 were negatively correlated with survival on TCGA analysis; while, hepatic miR-27a-3p was negatively correlated with Acsl1/Aldh2 expression in tumor/non-tumor tissues from fatty/non-fatty livers. CONCLUSIONS Maternal obesity plays a role in regulating cumulative susceptibility to HCC development in offspring over multiple generations through the miR-27a-3p-Acsl1/Aldh2 axis. LAY SUMMARY It is not currently known how maternal obesity affects the incidence of liver cancer in offspring. In this study, we identified a microRNA (miR-27a-3p) that was upregulated in obese mothers and could be passed on to their offspring. This microRNA enhanced the risk of liver cancer in offspring by regulating 2 genes (Acsl1 and Aldh2). This mechanism could be a future therapeutic target.

Abstract
BACKGROUND Lung cancer is the main cancer-related deaths worldwide. In this study, we explored the clinical prognostic significance and functional role of miR-939-3p in lung cancer. METHODS We analyzed the expression of miR-939-3p in lung cancer tissues and cells by qRT-PCR. The prognostic significance of miR-939-3p was investigated using the Kaplan-Meier survival and Cox regression analyses. The CCK-8 assay was used to determine the role of miR-939-3p in cell proliferation. Transwell assays were used to determine the effects of miR-939-3p on cell migration and invasion abilities. RESULTS The expression of miR-939-3p was upregulated in cancer tissues and cell lines compared with adjacent normal tissues and normal cells, respectively. The upregulated miR-939-3p was significantly associated with lymph node metastasis, TNM stage and poor prognosis of lung cancer patients. After the transfection of miR-939 mimic, overexpression of miR-939-3p promoted lung cancer cell proliferation, migration, and invasion. CONCLUSION These findings suggested that miR-939-3p acts as an oncogene and promotes cell proliferation, migration, and invasion in lung cancer. miR-939-3p may be a potential independent prognostic biomarker in lung cancer.

Abstract
BACKGROUND Thyroid cancer is the most common malignant tumor with relatively high incidence and mortality in endocrine system. Research about thyroid cancer-related targets is the basis for the diagnosis of thyroid cancer and the development of new drugs. However, the predictive value of long non-coding RNA (lncRNA) for the diagnosis and prognosis of thyroid cancer is still in the preliminary stage of exploration. Thus, we for the first time investigated the effects and associated regulatory mechanism of lncRNA Forkhead box D3 antisense RNA 1 (FOXD3-AS1) in thyroid cancer in vitro and in vivo. METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was used to measure the expression of lncRNA FOXD3-AS1 and miR-296-5p. Cell proliferation was detected through colony formation assay. Cell cycle was analyzed through flow cytometry. Cell mobility was valued through transwell invasion assay and wound healing assay. Western blotting was used to examine the expression of proteins related to cell proliferation and cell migration and TGF-β1/Smads signaling pathway. Luciferase reporter assay was used to verify the targeting relationship between FOXD3-AS1 and miR-296-5p. Tumor xenograft model was established and immunohistochemistry (IHC) was used to examine the expression of Ki67 and VEGF. RESULTS We found that the expression of lncRNA FOXD3-AS1was upregulated and it had negative correlation with the level of miR-296-5p in thyroid cancer tissues and cells. LncRNA FOXD3-AS1 knockdown effectively suppressed cell proliferation and cell invasion in vitro. Further study revealed that miR-296-5p was a target of lncRNA FOXD3-AS1 and FOXD3-AS1 exerted anti-tumor effect through up-regulating miR-296-5p. Moreover, we found that FOXD3-AS1 knockdown suppressed the aggressive biological behaviors of thyroid cancer through inactivating the TGF-β1/Smads signaling pathway. Subsequently, the in vivo experiments further verified that the FOXD3-AS1/miR-296-5p axis exerted obvious anti-tumor effect through inhibiting tumor growth and metastasis and the TGF-β1/Smads signaling pathway was also inactivated in vivo by the inhibition of FOXD3-AS1. CONCLUSION Inhibition of LncRNA FOXD3-AS1 suppresses the aggressive biological behaviors of thyroid cancer via elevating miR-296-5p and inactivating TGF-β1/Smads signaling pathway.

Abstract
Non-coding RNA (ncRNA) plays an important role in regulating biological activities of animals and plants, and the representative ones are microRNA (miRNA) and long non-coding RNA (lncRNA). Recent research has found that predicting the interaction between miRNA and lncRNA is the primary task for elucidating their functional mechanisms. Due to the small scale of data, a large amount of noise, and the limitations of human factors, the prediction accuracy and reliability of traditional feature-based classification methods are often affected. Besides, the structure of plant ncRNA is complex. This paper proposes an ensemble deep-learning model based on convolutional neural network (CNN) and independently recurrent neural network (IndRNN) for predicting the interaction between miRNA and lncRNA of plants, namely, CIRNN. The model uses CNN to explore the functional features of gene sequences automatically, leverages IndRNN to obtain the representation of sequence features, and learns the dependencies among sequences; thus, it overcomes the inaccuracy caused by human factors in traditional feature engineering. The experiment results show that the proposed model is superior to shallow machine-learning and existing deep-learning models when dealing with large-scale data, especially for the long sequence.

Abstract
Lung cancer is the leading cause of cancer-related mortality worldwide. Recently, accumulating data indicate that long noncoding RNAs (LncRNAs) function as novel crucial regulators of diverse biological processes, including proliferation and metastasis, in tumorigenesis. Lnc NONHSAT081507.1 (LINC81507) is associated with lung adenocarcinoma. However, its pathological role in non-small cell lung cancer (NSCLC) remains unknown. In our study we investigated the role of LINC81507 in NSCLC. The expression of LINC81507 was analyzed in 105 paired NSCLC tumor specimens and paired adjacent non-tumorous tissues from NSCLC patients by real-time quantitative PCR (RT-qPCR). Gain- and loss-of-function experiments were conducted to investigate the functions of LINC81507, miR-199b-5p and CAV1. Reduced expression of LINC81507 resulted in cell growth, proliferation, migration and epithelial–mesenchymal transition (EMT) in NSCLC cells, whereas ectopic overexpression of LINC81507 resulted in the opposite effects both in vitro and in vivo. Nuclear and Cytoplasmic fractionation assays showed LINC81507 mainly resided in cytoplasm. Bioinformatics analysis and dual-luciferase assays revealed that miR-199b-5p was a direct target of LINC81507 through binding Ago2. Mechanistic analysis demonstrated that miR-199b-5p specifically targeted the Caveolin1 (CAV1) gene, and LINC81507 inactivated the STAT3 pathway in a CAV1-dependent manner. Taken together, LINC81507 is decreased in NSCLC and functions as a sponge to miR-199b-5p to regulate CAV1/STAT3 pathway, which suggests that LINC81507 serve as a tumor suppressor and potential therapeutic target and biomarker for metastasis and prognosis in NSCLC.

Abstract
Background Glioblastoma multiforme (GBM) is one of the most aggressive brain tumors among human beings. In this study, we explored the functions of human microRNA-1270 (hsa-miR-1270) on GBM cancer cell proliferation, migration, and tumorigenesis. Materials and methods In GBM cell lines and clinical tissues, hsa-miR-1270 expression was probed by quantitative real-time PCR (qRT-PCR). In LN-18 and A172 cells, hsa-miR-1270 was upregulated by lentiviral transduction. The effects of hsa-miR-1270 upregulation on GBM in vitro and in vivo functions were probed by proliferation, migration, and xenograft assays, respectively. The correlation between hsa-miR-1270 and Wilms’ tumor gene (WT1) was probed by dual-luciferase activity assay, qRT-PCR, and Western blot. WT1 was then secondarily over-expressed in hsa-miR-1270-upregulated LN-18 and A172 cells, to explore its mechanisms in GBM’s association with hsa-miR-1270. Results Hsa-miR-1270 was significantly downregulated in both GBM cell lines and clinical tumors. Upregulating hsa-miR-1270 considerably suppressed GBM cell proliferation and migration in vitro and xenograft in vivo. WT1 was inversely correlated with hsa-miR-1270 in GBM. WT1 overexpression in hsa-miR-1270-upregulated GBM cells reversed the anticancer functions of hsa-miR-1270 on cancer proliferation and migration. Conclusion Hsa-miR-1270 upregulation may have suppressing effects on GBM cancer cells, likely by functionally acting through WT1.

Abstract
Emerging evidence suggests the critical function of microRNAs in regulating the growth of cancer cells. In the present study, it was demonstrated that miR-221-3p was overexpressed in non-small cell lung cancer (NSCLC) tissues and cell lines compared with that noted in the normal controls. Downregulation of miR-221-3p suppressed the proliferation, colony formation and invasion of NSCLC cells. To further understand the molecular mechanisms underlying the potential oncogenic function of miR-221-3p in NSCLC, the downstream targets of miR-221-3p were predicted using bioinformatic databases. The prediction suggested the cell cycle regulator p27 as one of the targets of miR-221-3p. Molecular experiments showed that miR-221-3p was able to bind with the 3′-untranslated region (UTR) of p27 and decreased the expression of p27 in NSCLC cells. Consistent with the suppressive role of p27 in controlling cell cycle progression, overexpression of miR-221-3p decreased the expression of p27 and promoted cell cycle progression from G1 to S phase. Collectively, our findings identified miR-221-3p as a novel regulator of NSCLC cell growth via modulating the expression of p27.

Abstract
Background lncRNAs are widely involved in multiple malignancies including colorectal cancer (CRC). The expression and function of long intergenic non-protein coding RNA 460 (LINC00460) in CRC remains obscure. Methods In the present study, quantitative real-time PCR assays were applied to detect the expression changes of LINC00460 and microRNA-939-5p (miR-939-5p) in CRC tissue specimens and cell lines. Western blot assays were used to measure the changes of LIMK2. Bioinformatics analysis, luciferase assays, and RNA pull-down assays were applied to determine the targeting binding effect between LINC00460 and miR-939-5p as well as LIMK2 and miR-939-5p. Transwell assays were used to evaluate the metastatic ability changes of CRC line HT29 and LOVO cells. Results We found that LINC00460 was upregulated and closely correlated to clinicopathological features and poor prognosis of patients with CRC. Functionally, we elucidated that LINC00460 promoted metastasis in CRC cell lines HT29 and LOVO. Further, we showed that LIMK2 was a downstream effector in the LINC00460-induced promotion of metastasis in CRC cells HT29 and LOVO. Through online bioinformatics analysis, LINC00460 and LIMK2 were demonstrated to share similar microRNA response elements for miR-939-5p. Then, LINC00460 and LIMK2 were verified to be the targets of miR-939-5p via a luciferase assay and an RNA pull-down assay. Also, miR-939-5p was showed to suppress metastasis by targeting of LIMK2. Lastly, we revealed that LINC00460 promoted LIMK2-mediated metastasis via miR-939-5p sponging in CRC cells HT29 and LOVO. Conclusion The findings of this study showed that LINC00460 works as an oncogene in CRC and promoted CRC cell metastasis via regulation of miR-939-3p/LIMK2 axial. The present study might provide a new target in treating CRC.

Abstract
Cancer-related mortality is a leading cause of death among both men and women around the world. Target-specific therapeutic drugs, early diagnosis, and treatment are crucial to reducing the mortality rate. One of the recent trends in modern medicine is "Theranostics," a combination of therapeutics and diagnosis. Extensive interest in magnetic nanoparticles (MNPs) and ultrasmall superparamagnetic iron oxide nanoparticles (NPs) has been increasing due to their biocompatibility, superparamagnetism, less-toxicity, enhanced programmed cell death, and auto-phagocytosis on cancer cells. MNPs act as a multifunctional, noninvasive, ligand conjugated nano-imaging vehicle in targeted drug delivery and diagnosis. In this review, we primarily discuss the significance of the crystal structure, magnetic properties, and the most common method for synthesis of the smaller sized MNPs and their limitations. Next, the recent applications of MNPs in cancer therapy and theranostics are discussed, with certain preclinical and clinical experiments. The focus is on implementation and understanding of the mechanism of action of MNPs in cancer therapy through passive and active targeting drug delivery (magnetic drug targeting and targeting ligand conjugated MNPs). In addition, the theranostic application of MNPs with a dual and multimodal imaging system for early diagnosis and treatment of various cancer types including breast, cervical, glioblastoma, and lung cancer is reviewed. In the near future, the theranostic potential of MNPs with multimodality imaging techniques may enhance the acuity of personalized medicine in the diagnosis and treatment of individual patients.

Abstract
Numerous microRNAs (miRNA/miRs) have been reported to be associated with the initiation and progression of non‑small cell lung cancer (NSCLC). The aim of the present study was to examine the expression and biological role of miR‑939 in human NSCLC, in vitro. Reverse transcription‑quantitative polymerase chain reaction analysis was used to evaluate the expression of miR‑939 in NSCLC tissues. Cell Counting Kit‑8, 5‑ethynyl‑29‑deoxyuridine and Transwell assays were also used to determine the effects of miR‑939 on tumor cell proliferation and invasion in two human NSCLC cell lines (H1299 and SPCA1). Furthermore, tissue inhibitor of metalloproteinases 2 (TIMP2) was confirmed to be a target of miR‑939 by luciferase reporter assay, western blotting and bioinformatics analysis. Following downregulation of miR‑939 expression, cell proliferative and invasive abilities were significantly suppressed. Collectively, these findings indicated that the knockdown of miR‑939 may inhibit cell proliferation and invasion by regulating the expression of TIMP2 in NSCLC cells. Thus, miR‑939 may be a potential target in the treatment of NSCLC, although this requires further investigation.

Abstract
PURPOSE We intended to evaluate expression and mechanisms of human microRNA 1270 (hsa-miR-1270) in papillary thyroid cancer (PTC). METHODS In PTC cell lines and human PTC tumors, hsa-miR-1270 expressions were evaluated by qRT-PCR. Hsa-miR-1270 was downregulated in TPC1 and K1 cells via lentiviral transduction. Its effects on PTC cancer cell proliferation, migration and in vivo transplantation were assessed, respectively. Potential targeting of hsa-miR-1270 on downstream gene, Suppressor Of Cancer Cell Invasion (SCAI), was assessed. In hsa-miR-1270-downregulated PTC cells, SCAI was further downregulated to examine its associating role in hsa-miR-1270-mediated regulation on cancer cell proliferation and migration. RESULTS Hsa-miR-1270 was aberrantly upregulated in PTC cell lines and human PTC tumors. In TPC1 and K1 cells, lentivirus-mediated hsa-miR-1270 downregulation suppressed cancer cell proliferation, migration and in vivo transplantation. Hsa-miR-1270 binds SCAI and inversely regulated SCAI gene expression in PTC cells. SCAI downregulation removed the suppressing effects of hsa-miR-1270 downregulation in human PTC cells. CONCLUSION Hsa-miR-1270 downregulation may suppress human PTC cell development both in vitro and in vivo. The regulatory mechanism of hsa-miR-1270 in PTC may be primarily associated with SCAI.

Abstract
Biomarker detection is one of the most important and challenging problems in cancer studies. Recently, non-coding RNA based biomarkers such as miRNA expression levels have been used for early diagnosis of many cancer types. In this study, a systems biology approach was used to detect novel miRNA based biomarkers for CRC diagnosis in early stages. The mRNA expression data from three CRC stages (Low-grade Intraepithelial Neoplasia (LIN), High-grade Intraepithelial Neoplasia (HIN) and Adenocarcinoma) were used to reconstruct co-expression networks. The networks were clustered to extract co-expression modules and detected low preserved modules among CRC stages. Then, the experimentally validated mRNA-miRNA interaction data were applied to reconstruct three mRNA-miRNA bipartite networks. Twenty miRNAs with the highest degree (hub miRNAs) were selected in each bipartite network to reconstruct three bipartite subnetworks for further analysis. The analysis of these hub miRNAs in the bipartite subnetworks revealed 30 distinct important miRNAs as prognostic markers in CRC stages. There are two novel CRC related miRNAs (hsa-miR-190a-3p and hsa-miR-1277-5p) in these 30 hub miRNAs that have not been previously reported in CRC. Furthermore, a drug-gene interaction network was reconstructed to detect potential candidate drugs for CRC treatment. Our analysis shows that the hub miRNAs in the mRNA-miRNA bipartite network are very essential in CRC progression and should be investigated precisely in future studies. In addition, there are many important target genes in the results that may be critical in CRC progression and can be analyzed as therapeutic targets in future research.

Abstract
Epithelial ovarian cancer (EOC) patients frequently suffer from thrombocytosis, which leads to a poor prognosis. However, the mechanism underlying platelet regulation of biological behavior in EOC remains unclear. The associations between clinicopathological characteristics and thrombocytosis in 171 EOC patients were studied, preoperative thrombocytosis was significantly associated with the stage, metastasis scope, level of preoperative CA125 and overall survival. When SKOV3 cells were cocultured with platelet microparticles (PMPs), the expression of molecules associated with epithelial-mesenchymal transition (EMT) was increased. The proliferation and migration of SKOV3 cells were also enhanced. Based on the miRNA microarray of the PMPs derived between thrombin-stimulating and apoptotic platelets, we demonstrated that over-expression or complete knockdown of miR-939 in the SKOV3 cells strengthened or weakened EMT. Secretory phospholipase A2 type IIA (sPLA2-IIa) has been shown to mediate PMPs intake by SKOV3 cells. The knockdown of sPLA2-IIa in SKOV3 cells verified that PMPs were involved in crosstalk during the regulation of cancer cells by transferring miRNA. This study revealed an important role for PMPs in the crosstalk of platelets and cancer cells through miR-939 shedding mediated by sPLA2-IIa, which enables EOC to undergo EMT and enhances cancer progression. Our findings pave the way for developing a novel therapeutic strategy for EOC targets such as PMPs, miR-939 or sPLA2-IIa.

The results of quantitative PCR analysis revealed that the expression levels of miR-1244 in cisplatin‑treated A549 and NCI-H522 human lung cancer cell lines were lower than those in untreated A549 and NCI-H522 cells. Similarly, the expression level of miR-1244 in NSCLC tissue samples from cisplatin-treated patients was also lower than that in non-cisplatin-treated NSCLC patients. Notably, the overall survival times of cisplatin-treated NSCLC patients with high miR-1244 expression were superior to those patients with low miR-1244 expression. We found that overexpression of miR-1244 suppressed cell viability and increased LDH toxicity in cisplatin-treated A549 and NCI-H522 cells. Additionally, overexpression of miR-1244 induced the apoptosis of cisplatin-treated A549 and NCI-H522 cells. Furthermore, overexpression of miR-1244 promoted caspase-3 activity and p53 and Bax protein expression, and suppressed myocyte enhancer factor 2D (MEF2D) and cyclin D1 protein expression in cisplatin‑treated A549 and NCI-H522 cells. Small interfering RNA (siRNA) targeting MEF2D suppressed the protein expression of MEF2D, and was able to decrease the proliferation, promote caspase-3 activity, p53 and Bax protein expression and inhibit cyclin D1 protein expression in cisplatin-treated A549 and NCI-H522 cells following the overexpression of miR-1244. In summary, we found that miR-1244 affected cisplatin-treated NSCLC via MEF2D expression.

Abstract
Fatty acid synthase (FASN) has emerged as a unique oncologic target for the treatment of cancers, including hepatocellular carcinoma (HCC). However, effective inhibitors of FASN for cancer treatment are lacking. MicroRNAs (miRNAs) have emerged as novel and endogenic inhibitors of gene expression. In the present study, we aimed to investigate the role of miR‑1207‑5p in HCC and the regulation of FASN through miR‑1207‑5p. The expression of miR-1207-5p was markedly reduced in HCC tissues and cell lines as detected with real‑time quantitative polymerase chain reaction (qPCR). Overexpression of miR-1207-5p significantly suppressed the cell growth and invasion of HCC cells. By contrast, inhibition of miR‑1207‑5p exhibited an opposite effect. Bioinformatics analysis showed that FASN is a predicted target of miR‑1207‑5p which was validated by dual‑luciferase reporter assay, qPCR and western blot analysis. Overexpression of miR‑1207‑5p inhibited the Akt/mTOR signalling pathway, and promotion of this pathway was noted following inhibition of miR‑1207‑5p. Rescue experiments showed that the restoration of FASN expression partially reversed the inhibitory effect of miR‑1207‑5p on cell growth, invasion and Akt phosphorylation. In conclusion, our study suggests that miR‑1207‑5p/FASN plays an important role in HCC, and provides novel insight into developing new inhibitors for FASN for therapeutic interventions for HCC.

Abstract
Cancer is an extremely diverse and complex disease that results from various genetic and epigenetic changes such as DNA copy-number variations, mutations, and aberrant mRNA and/or protein expression caused by abnormal transcriptional regulation. The expression profiles of certain microRNAs (miRNAs) and messenger RNAs (mRNAs) are closely related to cancer progression stages. In the past few decades, DNA microarray and next-generation sequencing techniques have been widely applied to identify miRNA and mRNA signatures for cancers on a genome-wide scale and have provided meaningful insights into cancer diagnosis, prognosis and personalized medicine. In this review, we summarize the progress in genome-wide analysis of miRNAs and mRNAs as cancer biomarkers, highlighting their diagnostic and prognostic roles.
