[PMID: 38330619 DOI: 10.1016/j.prp.2024.155190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 01/30/2024] [Accepted: 01/31/2024] [Indexed: 02/10/2024]
Abstract
The in-depth exploration of long non-coding RNAs (lncRNAs) reveals their pivotal and diverse roles in various disorders, particularly cancer. Within this intricate landscape, thymopoietin-antisense RNA-1 (TMPO-AS1) emerges as a noteworthy instigator of oncogenesis in humans. This exhaustive review seeks to intricately unravel the present understanding of TMPO-AS1, emphasizing its molecular foundations and highlighting its clinical applications in the realm of cancer research. TMPO-AS1 consistently exhibits heightened expression across a spectrum of cancer types, encompassing lung, colorectal, breast, cervical, bladder, pancreatic, hepatocellular, gastric, ovarian, and osteosarcoma. Elevated levels of TMPO-AS1 are intricately linked to unfavorable prognoses, accompanied by distinctive clinical and pathological characteristics. Functionally, TMPO-AS1 showcases its prowess in enhancing cancer cell migration, invasion, proliferation, and orchestrating epithelial-mesenchymal transition (EMT) through a myriad of molecular mechanisms. These mechanisms entail intricate interactions with proteins, microRNAs, and intricate signaling pathways. Furthermore, TMPO-AS1 is intricately involved in regulating critical cellular processes, including apoptosis and the cell cycle. The mounting evidence converges towards the potential of TMPO-AS1 serving as a diagnostic and prognostic biomarker, further entwined with its potential role in influencing chemoresistance in cancer. This potential is underscored by its consistent associations with clinical outcomes and treatment responses. This comprehensive investigation not only consolidates our existing knowledge of TMPO-AS1's multifaceted roles but also sheds illuminating insights on its profound significance in the intricate landscape of cancer biology, paving the way for potential applications in clinical practice.

Zhou J, Wang T, Zhang H, Liu J, Wei P, Xu R, Yan Q, Chen G, Li W, Gao SJ, Lu C. KSHV vIL-6 promotes SIRT3-induced deacetylation of SERBP1 to inhibit ferroptosis and enhance cellular transformation by inducing lipoyltransferase 2 mRNA degradation. PLoS Pathog 2024; 20:e1012082. [PMID: 38470932 PMCID: PMC10959363 DOI: 10.1371/journal.ppat.1012082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 03/22/2024] [Accepted: 02/27/2024] [Indexed: 03/14/2024] Open
Abstract
Ferroptosis, a defensive strategy commonly employed by the host cells to restrict pathogenic infections, has been implicated in the development and therapeutic responses of various types of cancer. However, the role of ferroptosis in oncogenic Kaposi's sarcoma-associated herpesvirus (KSHV)-induced cancers remains elusive. While a growing number of non-histone proteins have been identified as acetylation targets, the functions of these modifications have yet to be revealed. Here, we show KSHV reprogramming of host acetylation proteomics following cellular transformation of rat primary mesenchymal precursor. Among them, SERPINE1 mRNA binding protein 1 (SERBP1) deacetylation is increased and required for KSHV-induced cellular transformation. Mechanistically, KSHV-encoded viral interleukin-6 (vIL-6) promotes SIRT3 deacetylation of SERBP1, preventing its binding to and protection of lipoyltransferase 2 (Lipt2) mRNA from mRNA degradation resulting in ferroptosis. Consequently, a SIRT3-specific inhibitor, 3-TYP, suppresses KSHV-induced cellular transformation by inducing ferroptosis. Our findings unveil novel roles of vIL-6 and SERBP1 deacetylation in regulating ferroptosis and KSHV-induced cellular transformation, and establish the vIL-6-SIRT3-SERBP1-ferroptosis pathways as a potential new therapeutic target for KSHV-associated cancers.

Abstract
Circular RNAs (circRNAs) are single-stranded, covalently closed RNA molecules formed by mRNA exon back-splicing. Although the circRNA functions remain largely unknown, their currently known biological activities include: acting as competing endogenous RNA (ceRNA) to adsorb microRNA (miRNA), binding proteins, regulating transcription or splicing, and ability to be translated into proteins or peptides. A growing number of studies have found that many circRNAs are abnormally expressed in various cancers, and their dysregulation is highly correlated with tumor progression. Therefore, diagnosis and treatment using circRNAs as biomarkers and therapeutic targets, respectively, has gradually become an attractive research topic. In this review, we introduced the canonical biogenesis pathways and degradation mechanisms of circRNAs. In addition, we examined the biological functions of circRNAs in vivo. Finally, we discussed the current clinical applications and challenges faced by circRNA, and proposed future directions for this promising research field.

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
Background: The abundant immune-related long non-coding RNA (IRLNRs) in immune cells and immune microenvironment have the potential to forecast prognosis and evaluate the effect of immunotherapy. IRLNRs analysis will provide a new perspective for LUAC research. Methods: We calculated the immune score of each sample according to the expression levels of immune-related genes (IRGs) and screened the survival-related IRLNRs (sIRLNRs) by Cox regression analysis. The expression levels of AC068338.3 and AL691432.2 in tissues and cell lines were confirmed by RT-qPCR. Results: 36 IRLNRs were selected by Pearson correlation analysis. Ten sIRLNRs were significantly correlated with the clinical outcomes of LUAC patients. Five sIRLNRs were identified by multivariate COX regression analysis to establish the immune-related risk score model (IRRS). The overall survival (OS) in the high-risk group was shorter than that in the low-risk group. IRRS could be an independent prognostic factor with significant survival correlation The distributions of immune gene concentrations were different between high-risk group and low-risk group. Furthermore, we further verified that the expression levels of AC068338.3 and AL691432.2 in different LUAC cell lines and tumor tissues were lower than that in Human bronchial epithelial cell (HBE) and adjacent tissues respectively. The lower expression levels of AC068338.3 and AL691432.2 were detected with the more advance T-stages. Conclusions: Our results highlighted some sIRLNRs with significant clinical correlations and demonstrated their monitored and prognostic values for LUAC patients. The results of this study may provide a new perspective for immunological research and immunotherapy strategies.

Abstract
This study aimed to investigate the underlying molecular pathogenic mechanism of Sec62 in hepatocellular carcinoma (HCC). Microarray analysis was conducted to profile the global gene expression in the HCC cell line Huh7 cells transfected with Sec62high vs. NC and Sec62low vs. NC. Ingenuity pathway analysis and gene set enrichment analysis were used to perform Sec62-related signaling pathway analysis from screened differentially expressed genes (DEGs). A protein-protein interaction network was constructed. Experimental validation of the expression of key DEGs was conducted. Hypoxia-induced tube formation was undertaken to investigate the role of Sec62 in angiogenesis. A total of 74 intersected DEGs were identified from Huh7 cells with Sec62high vs. NC and Sec62low vs. NC. Among them, 65 DEGs were correlated with the expression of Sec62. The P53 signaling pathway was found to be enriched in Huh7 cells with Sec62high vs. NC, while the acute phase response signaling pathway was enriched in Huh7 cells with Sec62low vs. NC. DEGs, such as serine protease inhibitor E (SERPINE) and tumor necrosis factor receptor superfamily, member 11B (TNFRSF11B), were not only identified as the lead genes of these enriched pathways, but were also found to be closely related to Sec62. Moreover, knockdown of Sec62 decreased the expression of SERPINE1 (plasminogen activator inhibitor type 1 (PAI-1)) and TNFRSF11B, whereas overexpression of Sec62 had the opposite effects. In addition, knockdown of Sec62 inhibited hypoxia-induced tube formation via PAI-1. Sec62 promoted pro-angiogenesis of HCC under hypoxia by regulating PAI-1, and it may be a crucial angiogenic switch in HCC.

Abstract
BACKGROUND Circ_0046600 was reported to promote hepatocellular carcinoma (HCC) cell migratory ability. However, the functional roles and mechanism of circ_0046600 in HCC remain largely unknown. METHODS Levels of genes and proteins were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot. In vitro experiments were performed using cell counting kit-8 (CCK-8), colony formation, transwell, flow cytometry and Western blot assays, respectively. The direct interactions between miR-1258 and circ_0046600 or SERPINE1 mRNA-binding protein 1 (SERBP1) was verified using dual-luciferase reporter and RNA immunoprecipitation (RIP) assays. Xenograft tumor model was established to perform in vivo assay. Exosomes were obtained from culture media by using the commercial kit. RESULTS Circ_0046600 was highly expressed in HCC tissues and cells. Silencing of circ_0046600 impaired HCC cell growth and metastasis in vitro, as well as impeded HCC tumor growth in vivo. Mechanistically, circ_0046600 could competitively target miR-1258 to prevent the degradation of its target gene SERBP1. Rescue assay showed that miR-1258 inhibition reversed the inhibitory effects of circ_0046600 silencing on HCC cell. Moreover, ectopic overexpression of miR-1258 suppressed cell growth and metastasis in HCC, which was abolished by SERBP1 up-regulation. Furthermore, circ_0046600 was packaged into exosomes and could be derived from HCC cells. CONCLUSION Circ_0046600 promoted HCC progression via up-regulating SERBP1 through sequestering miR-1258; besides that, circ_0046600 was packaged into exosomes and could be released from HCC cells.

Abstract
The long non-coding RNA, urothelial cancer-associated 1 (UCA1) is an important regulator in several tumors. However, to the best of our knowledge, the clinical roles of UCA1 in cervical cancer remain unclear. Thus, the present study aimed to investigate the function and mechanism of UCA1 in cervical cancer. Reverse transcription-quantitative PCR analysis was performed to detect UCA1 and microRNA (miR)-299-3p expression in cervical cancer tissues and cell lines. The Cell Counting Kit-8 and Transwell assays were performed to assess cell proliferation and invasion, respectively. Furthermore, the dual-luciferase reporter assay was performed to confirm the association between UCA1 and miR-299-3p. Rescue experiments were performed to determine the mechanism of the UCA1/miR-299-3p axis. The results demonstrated that UCA1 expression was upregulated in cervical cancer tissues and cell lines. Furthermore, overexpression of UCA1 enhanced the proliferation and invasion of cervical cancer cells, the effects of which were reversed following UCA1 knockdown. Notably, UCA1 interacted with miR-299-3p and negatively regulated miR-299-3p expression. In addition, miR-299-3p expression was downregulated in cervical cancer tissues and cell lines. Overexpression of miR-299-3p suppressed the proliferation and invasion of cervical cancer cells, reversing the effects of UCA1 knockdown on cervical cancer cell proliferation. Taken together, the results of the present study suggest that UCA1 promotes cell proliferation and invasion by regulating miR-299-3p expression in cervical cancer.

Abstract
Previous studies have shown that long non-coding RNA (lncRNA) MT1JP plays a role as a tumor suppressor in several types of cancer. The present study aimed to explore the role of MT1JP in hepatocellular carcinoma (HCC). Paired HCC and non-tumor tissues from 64 patients with HCC were subjected to RNA isolation and reverse transcription-quantitative PCR (RT-qPCR) to analyze the differential expression of MT1JP, microRNA (miR)-32 and phosphatase and tensin homolog (PTEN) in HCC. Cell transfections, followed by RT-qPCR and western blotting, were carried out to investigate the interactions among MT1JP, miR-32 and PTEN. The role of MT1JP, miR-32 and PTEN in regulating HCC cell proliferation was assessed using a Cell Counting Kit-8 assay. It was found that MT1JP was downregulated in HCC cancer tissues compared with that in non-cancer tissues. Survival analysis showed that patients with low MT1JP expression levels exhibited a significantly higher 5-year overall survival rate compared with patients with high MT1JP levels. The expression of MT1JP in HCC tissues was positively associated with PTEN and negatively associated with miR-32. Overexpression of MT1JP increased the expression levels of PTEN and decreased the expression levels of miR-32. Overexpression of miR-32 did not affect the expression of MT1JP but decreased the expression levels of PTEN and attenuated the effect of overexpression of MT1JP on the expression of PTEN. Overexpression of MT1JP and PTEN decreased the proliferation of HCC cells. Overexpression of miR-32 played an opposite role and attenuated the effects of overexpression of MT1JP. Therefore, MT1JP may upregulate PTEN by downregulating miR-32 to regulate HCC cell proliferation.

Abstract
Hepatocellular carcinoma (HCC) is notorious for its poor prognosis. Increasing evidence has demonstrated that semaphorin 3F (SEMA3F) plays key roles in initiation and progression of several types of human cancer. However, the specific role and mechanism of SEMA3F in HCC remains not fully determined. In this study, we first performed pan-cancer analysis for SEMA3F's expression and prognosis using The Cancer Genome Atlas (TCGA) and The Genotype-Tissue Expression (GTEx) data and found that SEMA3F might be a potential oncogene in HCC. Subsequently, noncoding RNAs (ncRNAs) contributing to SEMA3F overexpression were identified by a combination of a series of in silico analyses, including expression analysis, correlation analysis, and survival analysis. Finally, the TMPO-AS1/SNHG16-let-7c-5p axis was identified as the most potential upstream ncRNA-related pathway of SEMA3F in HCC. Moreover, SEMA3F level was significantly positively associated with tumor immune cell infiltration, biomarkers of immune cells, and immune checkpoint expression. Collectively, our findings elucidated that ncRNAs-mediated upregulation of SEMA3F correlated with poor prognosis and tumor immune infiltration in HCC.

Abstract
Long noncoding RNAs (lncRNAs) play essential roles in the occurrence and development of multiple human cancers. An accumulating body of researches have investigated thymopoietin antisense RNA 1 (TMPO-AS1) as a newly discovered lncRNA, which functions as an oncogenic lncRNA that is upregulated in various human malignancies and associated with poor prognosis. Many studies have detected abnormally high expression levels of TMPO-AS1 in multiple cancers, such as lung cancer, breast cancer, colorectal cancer (CRC), hepatocellular carcinoma, CRC, gastric cancer, ovarian cancer, thyroid cancer, esophageal cancer, Wilms tumor, cervical cancer, retinoblastoma, bladder cancer, osteosarcoma, and prostate cancer. TMPO-AS1 has been subsequently demonstrated to play a pivotal role in tumorigenesis and progression. The aberrantly expressed TMPO-AS1 acts as a competing endogenous RNA (ceRNA) that inhibits miRNA expression, thus activating the expression of downstream oncogenes. This study comprehensively summarizes the aberrant expressions of TMPO-AS1 as reported in the current literature and explains the relevant biological regulation mechanisms in carcinogenesis and tumor progression. Corresponding studies have indicated that TMPO-AS1 has a potential value as a promising biomarker or a target for cancer therapy.

[PMID: 34071109 PMCID: PMC8224659 DOI: 10.3390/biomedicines9060591] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 05/18/2021] [Accepted: 05/20/2021] [Indexed: 12/11/2022] Open
Abstract
MicroRNAs are a set of highly conserved non-coding RNAs that control gene expression at the post-transcriptional/translational levels by binding to the 3′-UTR of diverse target genes. Increasing evidence indicates that miRNAs not only play a vital role in many biological processes, but they are also frequently deregulated in pathological conditions, including cancer. The miR-320 family is one of many tumor suppressor families and is composed of five members, which has been demonstrated to be related to the repression of epithelial-mesenchymal transition (EMT) inhibition, cell proliferation, and apoptosis. Moreover, this family has been shown to regulate drug resistance, and act as a potential biomarker for the diagnosis, prognosis, and prediction of cancer. In this review, we summarized recent research with reference to the tumor suppressor function of miR-320 and the regulation mechanisms of miR-320 expression. The collected evidence shown here supports that miR-320 may act as a novel biomarker for cancer prognosis and therapeutic response to cancer treatment.

Abstract
Hsa_circ_0061395(circBACH1) and SERBP1(SERPINE1 mRNA binding protein 1) have been reported to play a carcinogenic role in HCC.In this study, circBACH1, microRNA(miR)-656-3p, and SERBP1 expression levels with quantitative real-time polymerase chain reaction (qRT-PCR) in HCC tissue specimens and cells.The protein levels of SERBP1, E-Cadherin, vimentin, and N-Cadherin were detected with western blotting.Cell proliferation, migration, invasion, and apoptosis were determined with CCK-8, colony formation, transwell, and flow cytometry assays.The targeting relatio-nship between circBACH1 or SERBP1 and miR-656-3p was verified by dual-lucifer- ase reporter assay.The role of circBACH1 was validated by xenograft assay.CircBAC- H1 and SERBP1 were upregulated in HCC tissues and cells.Both circBACH1 and SERBP1 knockdown constrained proliferation, migration, invasion, and EMT(epithel-ial-mesenchymal transition), and facilitated apoptosis of HCC cells in vitro.Knockdo-wn of circBACH1 reduced HCC growth in vivo. SERBP1 overexpression partially neutralized the repressive effect of circBACH1 silencing on malignant behaviors of HCC cells.CircBACH1 sponged miR-656-3p to elevate SERBP1 expression, thereby accelerating the progression of HCC.The research provided a new evidence to support the role of circBACH1 in HCC.
