Zhang Y, Ru N, Xue Z, Gan W, Pan R, Wu Z, Chen Z, Wang H, Zheng X. The role of mitochondria-related lncRNAs in characterizing the immune landscape and supervising the prognosis of osteosarcoma. J Bone Oncol 2023; 43:100506. [PMID: 37868616 PMCID: PMC10585401 DOI: 10.1016/j.jbo.2023.100506] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 09/24/2023] [Accepted: 10/03/2023] [Indexed: 10/24/2023] Open
Abstract
Mitochondrial damage is related to the functional properties of immune cells as well as to tumorigenesis and progression. Nevertheless, there is an absence concerning the systematic evaluation of mitochondria-associated lncRNAs (MALs) in the immune profile and tumor microenvironment of osteosarcoma patients. Based on transcriptomic and clinicopathological data from the TARGET database, MAL-related patterns were ascertained by consistent clustering, and gene set variation analysis of the different patterns was completed. Next, a MAL-derived scoring system was created using Cox and LASSO regression analyses and validated by Kaplan-Meier and ROC curves. The GSEA, ESTIMATE, and CIBERSORT algorithms were utilized to characterize the immune status and underlying biological functions in the different MAL score groups. MAL-derived risk scores were well stabilized and outperformed traditional clinicopathological features to reliably predict 5-year survival in osteosarcoma cohorts. Moreover, patients with increased MAL scores were observed to suffer from poorer prognosis, higher tumor purity, and an immunosuppressive microenvironment. Based on estimated half-maximal inhibitory concentrations, the low-MAL score group benefited more from gemcitabine and docetaxel, and less from thapsigargin and sunitinib compared to the high-MAL score group. Pan-cancer analysis demonstrated that six hub MALs were strongly correlated with clinical outcomes, immune subtypes, and tumor stemness indices in various common cancers. Finally, we verified the expression patterns of hub MALs in osteosarcoma with qRT-PCR. In summary, we identified the crosstalk between prognostic MALs and tumor-infiltrating immune cells in osteosarcoma, providing a potential strategy to ameliorate clinical stratification management.

Li X, Duan X, Wang W. MEG3 polymorphisms associated with peripheral blood leukocyte mitochondrial DNA copy number in PAHs-exposure workers. CHEMOSPHERE 2023; 344:140335. [PMID: 37778642 DOI: 10.1016/j.chemosphere.2023.140335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 07/01/2023] [Accepted: 09/28/2023] [Indexed: 10/03/2023]
Abstract
BACKGROUND Epidemiological studies have shown that exposure to Polycyclic aromatic hydrocarbons (PAHs) is associated with reduced mitochondrial DNA copy number (mtDNA-CN). Long non-coding RNA maternally expressed gene 3 (MEG3) is involved in mitochondrial function regulation. However, it is unknown whether single-nucleotide polymorphisms in the MEG3 can regulate the mtDNAcn in PAHs exposed populations. The aim of this study was to examine the effect of MEG3 genetic polymorphisms on the mtDNA-CN in PAHs exposed populations. MATERIALS AND METHODS We recruited 544 coke oven workers and 238 controls using random cluster sampling. High-performance liquid chromatography was used to detect the concentrations of four OH-PAHs (1-hydroxypyrene [1-OHPyr], 1-hydroxynathalene [1-OHNap], 2-hydroxynathalene [2-OHNap], and 3-hydroxyphenanthrene [3-OHPhe]) in urine. The mtDNA-CN of peripheral blood leukocytes was measured using the quantitative polymerase chain reaction method. Sequenom Mass ARRAY matrix-assisted laser desorption/ionization-time of flight mass spectrometry platform was used to detect ten polymorphisms in MEG3. RESULTS The OH-PAHs levels in the exposure group were significantly higher than those in the control group (P < 0.001). The mtDNA-CN in the exposure group was significantly lower than that in the control group (P < 0.001). A linear regression model revealed that PAHs-exposure (β [95% confidence interval, CI], -0.428 [-0.475, -0.381], P < 0.001), male gender (-0.052 [-0.098, -0.005], P = 0.029), genotype TT for MEG3 rs11859 (-0.088 [-0.142, -0.035], P = 0.001), and genotype GG for MEG3 rs7155428 (-0.114 [-0.210, -0.017], P = 0.021) were associated with decreased mtDNA-CN. CONCLUSION PAHs-exposure, male gender, genotype TT for rs11859, and genotype GG for rs7155428 were risk factors for mtDNA-CN.

Comprehensive analysis of mitochondrial dysfunction and necroptosis in intracranial aneurysms from the perspective of predictive, preventative, and personalized medicine. Apoptosis 2023; 28:1452-1468. [PMID: 37410216 PMCID: PMC10425526 DOI: 10.1007/s10495-023-01865-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/14/2023] [Indexed: 07/07/2023]
Abstract
Mitochondrial dysfunction and necroptosis are closely associated, and play vital roles in the medical strategy of multiple cardiovascular diseases. However, their implications in intracranial aneurysms (IAs) remain unclear. In this study, we aimed to explore whether mitochondrial dysfunction and necroptosis could be identified as valuable starting points for predictive, preventive, and personalized medicine for IAs. The transcriptional profiles of 75 IAs and 37 control samples were collected from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs), weighted gene co-expression network analysis, and least absolute shrinkage and selection operator (LASSO) regression were used to screen key genes. The ssGSEA algorithm was performed to establish phenotype scores. The correlation between mitochondrial dysfunction and necroptosis was evaluated using functional enrichment crossover, phenotype score correlation, immune infiltration, and interaction network construction. The IA diagnostic values of key genes were identified using machine learning. Finally, we performed the single-cell sequencing (scRNA-seq) analysis to explore mitochondrial dysfunction and necroptosis at the cellular level. In total, 42 IA-mitochondrial DEGs and 15 IA-necroptosis DEGs were identified. Screening revealed seven key genes invovled in mitochondrial dysfunction (KMO, HADH, BAX, AADAT, SDSL, PYCR1, and MAOA) and five genes involved in necroptosis (IL1B, CAMK2G, STAT1, NLRP3, and BAX). Machine learning confirmed the high diagnostic value of these key genes for IA. The IA samples showed higher expression of mitochondrial dysfunction and necroptosis. Mitochondrial dysfunction and necroptosis exhibited a close association. Furthermore, scRNA-seq indicated that mitochondrial dysfunction and necroptosis were preferentially up-regulated in monocytes/macrophages and vascular smooth muscle cells (VSMCs) within IA lesions. In conclusion, mitochondria-induced necroptosis was involved in IA formation, and was mainly up-regulated in monocytes/macrophages and VSMCs within IA lesions. Mitochondria-induced necroptosis may be a novel potential target for diagnosis, prevention, and treatment of IA.

Abstract
ANRIL (Antisense Noncoding RNA in the INK4 Locus), a long non-coding RNA encoded in the human chromosome 9p21 region, is a critical factor for regulating gene expression by interacting with multiple proteins and miRNAs. It has been found to play important roles in various cellular processes, including cell cycle control and proliferation. Dysregulation of ANRIL has been associated with several diseases like cancers and cardiovascular diseases, for instance. Understanding the oncogenic role of ANRIL and its potential as a diagnostic and prognostic biomarker in cancer is crucial. This review provides insights into the regulatory mechanisms and oncogenic significance of the 9p21 locus and ANRIL in cancer.

Abstract
BACKGROUND Urinary pan-cancer system is a general term for tumors of the urinary system including renal cell carcinoma (RCC), prostate cancer (PRAD), and bladder cancer (BLCA). Their location, physiological functions, and metabolism are closely related, making the occurrence and outcome of these tumors highly similar. Cuproptosis is a new type of cell death that is different from apoptosis and plays an essential role in tumors. Therefore, it is necessary to study the molecular mechanism of cuproptosis-related lncRNAs to urinary system pan-cancer for the prognosis, clinical diagnosis, and treatment of urinary tumors. METHOD In our study, we identified 35 co-expression cuproptosis-related lncRNAs (CRLs) from the urinary pan-cancer system. 28 CRLs were identified as prognostic-related CRLs by univariate Cox regression analysis. Then 12 CRLs were obtained using lasso regression and multivariate cox analysis to construct a prognostic model. We divided patients into high- and low-risk groups based on the median risk scores. Next, Kaplan-Meier analysis, principal component analysis (PCA), functional rich annotations, and nomogram were used to compare the differences between the high- and low-risk groups. Finally, the prediction of tumor immune dysfunction and rejection, gene mutation, and drug sensitivity were discussed. CONCLUSION Finally, the candidate molecules of the urinary system pan-cancer were identified. This CRLs risk model may be promising for clinical prediction of prognosis and immunotherapy response in urinary system pan-cancer patients.

Abstract
BACKGROUND With high morbidity and mortality, hepatocellular carcinoma (HCC) deserves further exploration in its pathogenesis mechanisms for promising prognostic and therapeutic markers. This research was conducted to dig out roles of exosomal ZFPM2-AS1 in HCC. METHODS The level of exosomal ZFPM2-AS1 in HCC tissue and cells was determined by Real-time fluorescence quantitative PCR. Pull-down assay and dual-luciferase reporter assay were performed to identify interactions between ZFPM2-AS1 and miRNA-18b-5p, as well as miRNA-18b-5p and PKM. Western blotting was employed to explore the potential regulatory mechanism. Several in vitro assays were conducted in mice xenograft and orthotopic transplantation models to investigate impacts of exosomal ZFPM2-AS1 on HCC development, metastasis, and macrophage infiltration. RESULTS ZFPM2-AS1 was activated in HCC tissue and cells, with high enrichment in HCC-derived exosomes. Exosomal ZFPM2-AS1 enhances the cell abilities and stemness of HCC. MiRNA-18b-5p was directly targeted by ZFPM2-AS1 which triggered PKM expression via sponging miR-18b-5p. Exosomal ZFPM2-AS1 modulated glycolysis via PKM in an HIF-1α dependent way in HCC, promoting M2 polarization, and macrophage recruitment. Furthermore, exosomal ZFPM2-AS1 enhanced HCC cell growth, metastasis, and M2 infiltration in vivo. CONCLUSIONS Exosomal ZFPM2-AS1 exerted regulatory function on the progression of HCC via miR-18b-5p/PKM axis. ZFPM2-AS1 could be promising biomarker for the diagnosis and therapies of HCC.

Abstract
Transcriptome complexity is emerging as an unprecedented and fascinating domain, especially by high-throughput sequencing technologies that have unveiled a plethora of new non-coding RNA biotypes. This review covers antisense long non-coding RNAs, i.e., lncRNAs transcribed from the opposite strand of other known genes, and their role in hepatocellular carcinoma (HCC). Several sense-antisense transcript pairs have been recently annotated, especially from mammalian genomes, and an understanding of their evolutionary sense and functional role for human health and diseases is only beginning. Antisense lncRNAs dysregulation is significantly involved in hepatocarcinogenesis, where they can act as oncogenes or oncosuppressors, thus playing a key role in tumor onset, progression, and chemoradiotherapy response, as deduced from many studies discussed here. Mechanistically, antisense lncRNAs regulate gene expression by exploiting various molecular mechanisms shared with other ncRNA molecules, and exploit special mechanisms on their corresponding sense gene due to sequence complementarity, thus exerting epigenetic, transcriptional, post-transcriptional, and translational controls. The next challenges will be piecing together the complex RNA regulatory networks driven by antisense lncRNAs and, ultimately, assigning them a function in physiological and pathological contexts, in addition to defining prospective novel therapeutic targets and innovative diagnostic tools.

Abstract
Hepatocellular carcinoma (HCC) is among the deadliest cancer in human malignancies. It is the most common and severe type of primary liver cancer. However, the molecular mechanisms underlying HCC pathogenesis remain poorly understood. Long non-coding RNAs (lncRNAs), a new kind of RNA and epigenetic factors, play a crucial role in tumorigenesis and the progression of HCC. LncRNAs are capable of promoting the autophagy, proliferation, and migration of tumor cells by targeting and modulating the expression of downstream genes in signaling pathways related to cancer; these transcripts modify the activity and expression of various tumor suppressors and oncogenes. LncRNAs could act as biomarkers for treatment approaches such as immunotherapy, chemotherapy, and surgery to effectively treat HCC patients. Improved knowledge regarding the aetiology of HCC may result from an advanced understanding of lncRNAs. Enhanced oxidative stress in the mitochondrial and Endoplasmic reticulum leads to the activation of unfolded protein response pathway that plays a crucial role in the pathophysiology of hepatocellular carcinoma. The mutual regulation between LncRNAs and Endoplasmic reticulum (ER) stress in cancer and simultaneous activation of the unfolded protein response (UPR) pathway determines the fate of tumor cells in HCC. Mitochondria-associated lncRNAs work as essential components of several gene regulatory networks; abnormal regulation of mitochondria-associated lncRNAs may lead to oncogenesis, which provides further insight into the understanding of tumorigenesis and therapeutic strategies.

Abstract
Non-small cell lung cancer (NSCLC) is the main histological subtype of lung cancer with a high incidence and mortality. Circular RNAs (circRNAs) exert vital functions in various cancers by acting as a sponge of miRNAs to abolish their inhibitory effect on target genes. This study aims to explore the biological function of circRNA NEDD4 binding protein 2 like 2 (circ-N4BP2L2) in NSCLC. We found that circ-N4BP2L2 was upregulated in NSCLC tissues and cells by using RT-qPCR. A549 cells were transfected with pcDNA-circN4BP2L2 or sh-circN4BP2L2 to obtain circN4BP2L2-overexpressed or -silenced cells, and then cell proliferation, invasion and apoptosis were determined. The results showed that knockdown of circ-N4BP2L2 repressed cell proliferation, invasion as well as mitochondrial function, and promoted cell apoptosis; while overexpression of circ-N4BP2L2 resulted in the opposite results. Mechanistically, the targeting correlations between miR-135a-5p and circ-N4BP2L2 or ADP-ribosylation factorlike 5B (ARL5B) were confirmed by using dual luciferase reporter, RNA pull-down and RNA immunoprecipitation assays. In addition, we found that circ-N4BP2L2 could promote the expression of ARL5B by serving as a sponge of miR-135a-5p. Moreover, rescue assays revealed that silencing miR-135a-5p or overexpressing ARL5B was able to abate the effects of circ-N4BP2L2 knockdown on malignant phenotypes and mitochondrial function of A549 cells. Finally, tumorigenicity assay demonstrated that circ-N4BP2L2 facilitated NSCLC tumor growth in vivo. Taken together, circ-N4BP2L2 enhanced NSCLC progression via the miR-135a-5p/ARL5B axis, which may provide a novel therapeutic target of NSCLC.

Abstract
BACKGROUND Radiotherapy is an important treatment for lung cancer, mainly by triggering DNA double-strand breaks to induce cell death. Blocking DNA damage repair can increase the radiosensitivity of tumor cells. Recent studies have identified long noncoding RNAs as key regulators in DNA damage repair. The lncRNA ANRIL was previously shown to be involved in homologous recombination (HR) repair, but its specific mechanism has not been fully elucidated. METHODS The downstream interacting miRNAs of ANRIL were predicted according to miRanda software. Fluorescence quantitative PCR was used to detect the expression levels of ANRIL and candidate miRNAs. Clone formation experiment and cell viability assays detect cell viability after ionizing radiation. Apoptosis assay was used to detect the apoptosis of cells after 8 h of ionizing radiation. Western blot analysis and immunofluorescence assays verified the protein expression levels of the downstream target molecule PARP1 of miR-7-5p and key molecules in the HR pathway. Fluorescent reporter gene experiments were used to verify the interaction between ANRIL and miR-7-5p and between miR-7-5p and PARP1. RESULTS Bioinformatics analysis and qPCR validation suggested that miR-7-5p might be a downstream molecule of ANRIL. The expression of miR-7-5p was up-regulated after knockdown of ANRIL, and the expression of miR-7-5p was down-regulated after overexpression of ANRIL. Meanwhile, there was a negative correlation between ANRIL and miR-7-5p expression changes before and after ionizing radiation. The luciferase reporter gene assay confirmed the existence of ANRIL binding site with miR-7-5p, and found that transfection of miR-7-5p inhibitor can reduce the radiation sensitivity of ANRIL-KD cells. A downstream target molecule of miR-7-5p related to HR repair, PARP1, was screened through website prediction. Subsequently, it was confirmed by Western blot and luciferase reporter assays that miR-7-5p could down-regulate the expression of PARP1, and there was a miR-7-5p binding site on the 3'UTR of PARP1 mRNA. This suggests that ANRIL may act as a competitive endogenous RNA to bind miR-7-5p and upregulate the expression of PARP1. Western blot and immunofluorescence staining were used to detect the expression changes of HR repair factors in ANRIL-KD cells after ionizing radiation, and it was found that knockdown of ANRIL can inhibit the expression of PARP1, BRCA1 and Rad51, hinder radiation-induced HR repair, and eventually result in resensitizing ANRIL-KD cells to ionizing radiation. CONCLUSIONS Our findings provide evidence that ANRIL targets the miR-7-5p/PARP1 axis to exert its regulatory effect on HR repair, suggesting that altering ANRIL expression may be a promising strategy to overcome radiation resistance.

Abstract
Liver is an important organ in body that performs vital functions such as detoxification. Liver is susceptible to development of cancers, and hepatocellular carcinoma (HCC) is among them. 75-85% of liver cancer cases are related to HCC. Therefore, much attention has been directed towards understanding factors mediating HCC progression. LncRNAs are epigenetic factors with more than 200 nucleotides in length located in both nucleus and cytoplasm and they are promising candidates in cancer therapy. Directing studies towards understanding function of lncRNAs in HCC is of importance. LncRNAs regulate cell cycle progression and growth of HCC cells, and they can also induce/inhibit apoptosis in tumor cells. LncRNAs affect invasion and metastasis in HCC mainly by epithelial-mesenchymal transition (EMT) mechanism. Revealing the association between lncRNAs and downstream signaling pathways in HCC is discussed in the current manuscript. Infectious diseases can affect lncRNA expression in mediating HCC development and then, altered expression level of lncRNA is associated with drug resistance and radio-resistance. Biomarker application of lncRNAs and their role in prognosis and diagnosis of HCC are also discussed to pave the way for treatment of HCC patients.

Abstract
BACKGROUND Circular RNAs (circRNAs) serve as critical regulatory factors in cancer development. Nonetheless, the potential regulatory mechanism of circRNA sorting nexin 27 (circ_SNX27) in hepatocellular carcinoma (HCC) is still unknown. METHODS The circ_SNX27, microRNA-637 (miR-637), and fibroblast growth factor receptor 1 (FGFR1) levels were quantified by quantitative real-time polymerase chain reaction and western blot analysis. Next, function experiments were conducted using in vitro assays and in vivo senograft study. The relationship between miR-637 with circ_SNX27 or FGFR1 was uncovered by dual-luciferase reporter and RNA pull-down assays. RESULTS The circ_SNX27 and FGFR1 levels were up-regulated, but miR-637 content was reduced in HCC. Circ_SNX27 down-regulation inhibited HCC cell proliferation, motility, and invasion and promoted apoptosis in vitro, as well as weakened tumor growth in vivo. Circ_SNX27 served as a sponge of miR-637 to promote FGFR1 expression. MiR-637 reduction abolished the restrained effect of circ_SNX27 absence on HCC cell development. Moreover, miR-637 curbed HCC cell malignant phenotype by regulating FGFR1. CONCLUSION Circ_SNX27 contributed to HCC development via miR-637/FGFR1 axis, offering a new idea for the treatment of HCC.

Abstract
Introduction Metabolic syndrome-associated cardiovascular disease (MetS-CVD) is a cluster of metabolism-immunity highly integrated diseases. Emerging evidence hints that mitochondrial energy metabolism may be involved in MetS-CVD development. The physiopathological role of ATP5MG, a subunit of the F0 ATPase complex, has not been fully elucidated. Methods In this study, we selected ATP5MG to identify the immunity-mediated pathway and mine drugs targeting this pathway for treating MetS-CVD. Using big data from public databases, we dissected co-expressed RNA (coRNA), competing endogenous RNA (ceRNA), and interacting RNA (interRNA) genes for ATP5MG. Results It was identified that ATP5MG may form ceRNA with COX5A through hsa-miR-142-5p and interplay with NDUFB8, SOD1, and MDH2 through RNA–RNA interaction under the immune pathway. We dug out 251 chemicals that may target this network and identified some of them as clinical drugs. We proposed five medicines for treating MetS-CVD. Interestingly, six drugs are being tested to treat COVID-19, which unexpectedly offers a new potential host-targeting antiviral strategy. Conclusion Collectively, we revealed the potential significance of the ATP5MG-centered network for developing drugs to treat MetS-CVD, which offers insights into the epigenetic regulation for metabolism-immunity highly integrated diseases.

Abstract
Pancreatic cancer (PC) is a highly malignant disease characterized by insidious onset, rapid progress, and poor therapeutic effects. The molecular mechanisms associated with PC initiation and progression are largely insufficient, hampering the exploitation of novel diagnostic biomarkers and development of efficient therapeutic strategies. Emerging evidence recently reveals that noncoding RNAs (ncRNAs), including long ncRNAs (lncRNAs) and microRNAs (miRNAs), extensively participate in PC pathogenesis. Specifically, lncRNAs can function as competing endogenous RNAs (ceRNAs), competitively sequestering miRNAs, therefore modulating the expression levels of their downstream target genes. Such complex lncRNA/miRNA/mRNA networks, namely, ceRNA networks, play crucial roles in the biological processes of PC by regulating cell growth and survival, epithelial-mesenchymal transition and metastasis, cancer stem cell maintenance, metabolism, autophagy, chemoresistance, and angiogenesis. In this review, the emerging knowledge on the lncRNA-associated ceRNA networks involved in PC initiation and progression will be summarized, and the potentials of the competitive crosstalk as diagnostic, prognostic, and therapeutic targets will be comprehensively discussed.

Abstract
Accumulating evidence has shown that long noncoding RNA GAS5 is a well-known tumor suppressor in the pathogenesis of a variety of human cancers. However, the detailed role of GAS5 in osteosarcoma is still largely unclear. In this study, we found that GAS5 was downregulated in human osteosarcoma tissues and cell lines compared with matched adjacent tissues and normal osteoblast cells. Overexpression of GAS5 could significantly suppress the growth and invasion of osteosarcoma cells, while downregulation of GAS5 promoted cell proliferation and invasion. We confirmed that GAS5 could directly bind with miR-23a-3p by using luciferase reporter gene and RNA immunoprecipitation and pull-down assay. Downregulation of miR-23a-3p repressed cell proliferation and invasion. Overexpression of miR-23a-3p counterbalanced the inhibition effect of GAS5 on cell proliferation and invasion. Further studies indicated that overexpression of GAS5 inhibited cell proliferation and metastasis by regulating phosphatase and tensin homolog (PTEN). PTEN was authenticated as a target of miR-23a-3p. Upregulation of GAS5 or silence of miR-23a-3p increased the level of PTEN, while downregulation of GAS5 or overexpression of miR-23a-3p suppressed the expression of PTEN. In addition, overexpression of GAS5 could neutralize the effect of downregulating PTEN on osteosarcoma cell functions. We proved that GAS5 regulated the viability and invasion of osteosarcoma cells through the PI3K/AKT pathway. Moreover, overexpression of GAS5 could inhibit tumor growth in a xenograft nude mouse model in vivo. In summary, GAS5 functions as a competing endogenous RNA, sponging miR-23a-3p, to promote PTEN expression and suppress cell growth and invasion in osteosarcoma by regulating the PI3K/AKT pathway.

Abstract
Non-coding natural antisense transcripts (ncNATs) are regulatory RNA sequences that are transcribed in the opposite direction to protein-coding or non-coding transcripts. These transcripts are implicated in a broad variety of biological and pathological processes, including tumorigenesis and oncogenic progression. With this complex field still in its infancy, annotations, expression profiling and functional characterisations of ncNATs are far less comprehensive than those for protein-coding genes, pointing out substantial gaps in the analysis and characterisation of these regulatory transcripts. In this review, we discuss ncNATs from an analysis perspective, in particular regarding the use of high-throughput sequencing strategies, such as RNA-sequencing, and summarize the unique challenges of investigating the antisense transcriptome. Finally, we elaborate on their potential as biomarkers and future targets for treatment, focusing on cancer.

Biochem Biophys Res Commun 2021; 571:96-103. [PMID: 34314996 DOI: 10.1016/j.bbrc.2021.07.035] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 07/06/2021] [Accepted: 07/09/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Hepatocellular carcinoma (HCC) has been verified as a really common cancer worldwide. Several studies have suggested that the suppression of malignancy growth can be traced to miR-199a-5p. Even though CDC25A could activate the tumorigenesis of various cancer by modulating cell cycle, the modulation of the miR-199a-5p/CDC25A axis is still not clear in HCC. Our aim is to identify the modulation of the miR-199a-5p/CDC25A axis in HCC. METHODS The expression of CDC25A and miR-199a-5p in HCC cells and tissues was assessed using qRT-PCR. After using western blot assay to confirm the protein level, luciferase reporter and RNA pull-down assays were performed to explore the relation between CDC25A and miR-199a-5p. Functional assays such as CCK8 assay, BrdU proliferation assay and flow cytometry analysis identified the cell progression. RESULTS Experimental findings indicated the downregulation of miR-199a-5p in HCC samples. It was also found that miR-199a-5p overexpression declined the development of the cells with HCC and that it could bind to CDC25A to suppress the progression of HCC. CONCLUSION Research suggested that miR-199a-5p could restrain the proliferation ability of HCC cells by regulating CDC25A, thus inducing cell-cycle arrest.

Abstract
Hepatocellular carcinoma (HCC) is among the utmost deadly human malignancies. This type of cancer has been associated with several environmental, viral, and lifestyle risk factors. Among the epigenetic factors which contribute in the pathogenesis of HCC is dysregulation of long non-coding RNAs (lncRNAs). These transcripts modulate expression of several tumor suppressor genes and oncogenes and alter the activity of cancer-related signaling axes. Several lncRNAs such as NEAT1, MALAT1, ANRIL, and SNHG1 have been up-regulated in HCC samples. On the other hand, a number of so-called tumor suppressor lncRNAs namely CASS2 and MEG3 are down-regulated in HCC. The interaction between lncRNAs and miRNAs regulate expression of a number of mRNA coding genes which are involved in the pathogenesis of HCC. H19/miR-15b/CDC42, H19/miR-326/TWIST1, NEAT1/miR-485/STAT3, MALAT1/miR-124-3p/Slug, MALAT1/miR-195/EGFR, MALAT1/miR-22/SNAI1, and ANRIL/miR-144/PBX3 axes are among functional axes in the pathobiology of HCC. Some genetic polymorphisms within non-coding regions of the genome have been associated with risk of HCC in certain populations. In the current paper, we describe the recent finding about the impact of lncRNAs in HCC.

[PMID: 33627127 PMCID: PMC7903704 DOI: 10.1186/s12935-020-01741-7] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2019] [Accepted: 12/25/2020] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a common cancer leading to high morbidity and mortality in worldwide. Previous studies revealed that SEC61 translocon alpha 1 subunit1 (SEC61A) can act as an oncogene in colon adenocarcinoma. However, the functions and molecular mechanism associated with HCC progression remain to be explored. This study aimed at exploring the role of SEC61A1 in HCC progression. METHODS EdU assay and colony formation assay were applied to assess cell proliferation. The migratory ability of transfected HCC cells was evaluated by transwell migration assay. Sphere formation assay was used to detect the stemneess of HCC cells. Bioinformatics analysis tools and mechanism experiments were used to predict and analyze the potential molecular mechanism associated with the upregulation of SEC61A1 in HCC cells. RESULTS Up-regulated SEC61A1 facilitated cell proliferation, migration and stemness in HCC cells. MiR-491-5p negatively regulated SEC61A1 and inhibited HCC cell proliferation and migration by targeting SEC61A1. VPS9D1 antisense RNA 1 (VPS9D1-AS1) could up-regulate SEC61A1 through sponging miR-491-5p. Early growth response 1 (EGR1) was identified as the upstream transcriptional activator for both SEC61A1 and VPS9D1-AS1. CONCLUSIONS Our study unveiled a novel molecular pathway facilitating HCC cell proliferation, migration and stemness, which may shed new insight into HCC treatment.

Front Cell Dev Biol 2021; 9:604400. [PMID: 33692995 PMCID: PMC7937634 DOI: 10.3389/fcell.2021.604400] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 01/14/2021] [Indexed: 12/18/2022] Open
Abstract
Background Long non-coding RNA (lncRNA) antisense non-coding RNA in the INK4 locus (ANRIL) is a base length of about 3.8 kb lncRNA, which plays an important role in several biological functions including cell proliferation, migration, and senescence. This study ascertained the role of lncRNA ANRIL in the senescence and osteogenic differentiation of inflamed periodontal ligament stem cells (iPDLSCs). Methods Healthy periodontal ligament stem cells (hPDLSCs) and iPDLSCs were isolated from healthy/inflamed periodontal ligament tissues, respectively. The proliferation abilities were determined by CCK-8, EdU assay, and flow cytometry (FCM). The methods of Western blot assay (WB), quantitative real-time polymerase chain reaction (qRT-PCR), alizarin red staining, alkaline phosphatase (ALP) staining, ALP activity detection, and immunofluorescence staining were described to determine the biological influences of lncRNA ANRIL on iPDLSCs. Senescence-associated (SA)-β-galactosidase (gal) staining, Western blot analysis, and qRT-PCR were performed to determine cell senescence. Dual-luciferase reporter assays were conducted to confirm the binding of lncRNA ANRIL and miR-7-5-p, as well as miR-7-5p and insulin-like growth factor receptor (IGF-1R). Results HPDLSCs and iPDLSCs were isolated and cultured successfully. LncRNA ANRIL and IGF-1R were declined, while miR-7-5p was upregulated in iPDLSCs compared with hPDLSCs. Overexpression of ANRIL enhanced the osteogenic protein expressions of OSX, RUNX2, ALP, and knocked down the aging protein expressions of p16, p21, p53. LncRNA ANRIL could promote the committed differentiation of iPDLSCs by sponging miR-7-5p. Upregulating miR-7-5p inhibited the osteogenic differentiation of iPDLSCs. Further analysis identified IGF-1R as a direct target of miR-7-5p. The direct binding of lncRNA ANRIL and miR-7-5p, miR-7-5p and the 3′-UTR of IGF-1R were verified by dual-luciferase reporter assay. Besides, rescue experiments showed that knockdown of miR-7-5p reversed the inhibitory effect of lncRNA ANRIL deficiency on osteogenesis of iPDLSCs. Conclusion This study disclosed that lncRNA ANRIL promotes osteogenic differentiation of iPDLSCs by regulating the miR-7-5p/IGF-1R axis.

Abstract
Background: Hepatocellular carcinoma (HCC) is a common malignancy worldwide. Radiofrequency ablation (RFA) is applied for treating HCC; however, insufficient RFA promotes HCC development and accelerates HCC recurrence. Therefore, the molecular functions underlying this process have gradually attracted attention. Aim of the study: We sought to examine whether GAS6-AS2 (also known as GAS6-DT: growth arrest specific 6 divergent transcript) played a role in the development of HCC after insufficient RFA. Methods: The in vitro model was established by heating Huh7 and MHCC97 cells in water bath at 47°C, named as Huh7-H and MHCC97-H. Colony formation, transwell and western blot assays were conducted for functional analysis. Results: GAS6-AS2 was upregulated in Huh7-H and MHCC97-H cells relative to Huh7 and MHCC97 cells. GAS6-AS2 deficiency hampered cell proliferation, migration, invasion, epithelial-mesenchymal transition, and stemness in Huh7-H and MHCC97-H cells. Moreover, microRNA-3619-5p (miR-3619-5p) combined with GAS6-AS2 and ARL2 (ADP ribosylation factor-like GTPase 2) was the target gene of miR-3619-5p. GAS6-AS2 served as the competing endogenous RNA (ceRNA) of ARL2 via absorbing miR-3619-5p. Conclusion: On the whole, present study uncovered a novel ceRNA mechanism of GAS6-AS2/miR-3619-5p/ARL2 in HCC after insufficient RFA, which might shed a new insight into treatment of HCC after insufficient RFA.
