Elpek GO. Tata-box-binding protein-associated factor 15 as a new potential marker in gastrointestinal tumors. World J Gastroenterol 2024; 30:3367-3372. [PMID: 39091718 PMCID: PMC11290397 DOI: 10.3748/wjg.v30.i28.3367] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2024] [Revised: 06/19/2024] [Accepted: 07/02/2024] [Indexed: 07/24/2024] Open
Abstract
In this editorial, the roles of tata-box-binding protein-associated factor 15 (TAF15) in oncogenesis, tumor behavior, and as a therapeutic target in cancers in the context of gastrointestinal (GI) tumors are discussed concerning the publication by Guo et al. TAF15 is a member of the FET protein family with a comprehensive range of cellular processes. Besides, evidence has shown that TAF15 is involved in many diseases, including cancers. TAF15 contributes to carcinogenesis and tumor behavior in many tumors. Besides, its relationship with the mitogen-activated protein kinases (MAPK) signaling pathway makes TAF15 a new target for therapy. Although, the fact that there is few studies investigating the expression of TAF15 constitutes a potential limitation in GI system, the association of TAF15 expression with aggressive tumor behavior and, similar to other organ tumors, the influence of TAF15 on the MAPK signaling pathway emphasize that this protein could serve as a new molecular biomarker to predict tumor behavior and target therapeutic intervention in GI cancers. In conclusion, more studies should be performed to better understand the prognostic and therapeutic role of TAF15 in GI tumors, especially in tumors resistant to therapy.

Hu C, Song S, Zhao S, Xue Z, Zhu X. METTL14 contributes to the progression of nasopharyngeal carcinoma through regulating the stability of AOC1 mRNA. Hereditas 2024; 161:20. [PMID: 38956710 PMCID: PMC11221105 DOI: 10.1186/s41065-024-00317-z] [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: 01/28/2024] [Accepted: 04/19/2024] [Indexed: 07/04/2024] Open
Abstract
BACKGROUND Nasopharyngeal carcinoma (NPC) is a malignant epithelial tumor of the nasopharyngeal mucosa with a high incidence rate all over the world. Methyltransferase-like 14 (METTL14) is a major RNA N6-adenosine methyltransferase implicated in tumor progression by regulating RNA function. This study is designed to explore the biological function and mechanism of METTL14 in NPC. METHODS METTL14 and Amine oxidase copper containing 1 (AOC1) expression were detected by real-time quantitative polymerase chain reaction (RT-qPCR). The protein levels of METTL14, AOC1, Cyclin D1, B-cell lymphoma-2 (Bcl-2), and N-cadherin were measured using western blot. Cell proliferation, cycle progression, apoptosis, migration, and invasion were assessed using 5-ethynyl-2'-deoxyuridine (EdU), Colony formation, flow cytometry, wound scratch, and transwell assays. The interaction between METTL14 and AOC1 was verified using RNA immunoprecipitation (RIP), methylated RNA immunoprecipitation (MeRIP), and dual-luciferase reporter assays. The biological role of METTL14 on NPC tumor growth was examined by the xenograft tumor model in vivo. RESULTS METTL14 and AOC1 were highly expressed in NPC tissues and cells. Moreover, METTL14 knockdown might block NPC cell proliferation, migration, invasion, and induce cell apoptosis in vitro. In mechanism, METTL14 might enhance the stability of AOC1 mRNA via m6A methylation. METTL14 silencing might repress NPC tumor growth in vivo. CONCLUSION METTL14 might boosted the development of NPC cells partly by regulating the stability of AOC1 mRNA, which provided a promising therapeutic target for NPC treatment.

Non-coding RNA-Mediated N6-Methyladenosine (m 6A) deposition: A pivotal regulator of cancer, impacting key signaling pathways in carcinogenesis and therapy response. Noncoding RNA Res 2024; 9:84-104. [PMID: 38075202 PMCID: PMC10700483 DOI: 10.1016/j.ncrna.2023.11.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 10/23/2023] [Accepted: 11/08/2023] [Indexed: 06/20/2024] Open
Abstract
The emergence of RNA modifications has recently been considered as critical post-transcriptional regulations which governed gene expression. N6-methyladenosine (m6A) modification is the most abundant type of RNA modification which is mediated by three distinct classes of proteins called m6A writers, readers, and erasers. Accumulating evidence has been made in understanding the role of m6A modification of non-coding RNAs (ncRNAs) in cancer. Importantly, aberrant expression of ncRNAs and m6A regulators has been elucidated in various cancers. As the key role of ncRNAs in regulation of cancer hallmarks is well accepted now, it could be accepted that m6A modification of ncRNAs could affect cancer progression. The present review intended to discuss the latest knowledge and importance of m6A epigenetic regulation of ncRNAs including mircoRNAs, long non-coding RNAs, and circular RNAs, and their interaction in the context of cancer. Moreover, the current insight into the underlying mechanisms of therapy resistance and also immune response and escape mediated by m6A regulators and ncRNAs are discussed.

Abstract
LINC00839 has captured significant attention within a spectrum of human disorders, including acute lung injury, osteoarthritis, and childhood obesity. Notably, aberrant expression patterns of LINC00839 have been observed across diverse cancer tissues and cell lines. LINC00839 emerges as an oncogenic factor in tumorigenesis and exerts a positive influence on tumor-associated behaviors. Its therapeutic potential for various cancers is underscored by its modulatory impact on pivotal signaling pathways, such as PI3K/AKT, OXPHOS, and Wnt/β-catenin. Additionally, LINC00839's role in reducing sensitivity to drug and radiotherapy interventions presents opportunities for targeted intervention. Furthermore, elevated LINC00839 expression indicates advanced clinicopathological features and foretells unfavorable prognoses, as validated by publications and comprehensive analyses of tumor types using TCGA datasets. This review elucidates the multiple regulatory mechanisms and functional implications of LINC00839 in various diseases, especially malignancies, emphasizing its potential as a predictive biomarker and therapeutic target across multiple disease domains in humans.

Abstract
The present study aimed to investigate the association between the expression profiles of long non-coding RNAs (lncRNAs) and the clinical characteristics or prognosis of patients with nasopharyngeal carcinoma (NPC). The findings presented in the present review may provide novel strategies for the prevention and treatment of NPC. For the analyses, medical databases, including PubMed, Web of Science and Cochrane library were searched using specific search terms, search strategies and screening strategies. Endnote X9 document management software was then employed to extract documents from January, 2010 to May, 2023. Data were extracted following the prescribed standards. Review Manager 5.4 and STATA 12.0 data analysis software were used for data analysis. A total of 490 publications were analyzed for inclusion. In total, 29 publications, composed of 24 studies with upregulated lncRNAs and 5 studies with downregulated lncRNAs, were included in the final analysis. The analysis revealed that the upregulation of lncRNAs was significantly associated with T stage, N stage and clinical stage, as well as with the overall survival (OS) and disease-free survival (DFS) of patients with NPC (P<0.05). However, there was no significant association between the upregulated lncRNAs and sex, M stage or relapse-free survival (RFS) (P>0.05). On the other hand, the suppression of lncRNA expression was significantly associated with N stage, M stage, clinical stage and the OS of patients with NPC (P<0.05), but not with T stage and RFS (P>0.05). Taken together, the present review demonstrates that the up- and downregulation of different lncRNAs was associated with an advanced clinical stage and a shorter OS of patients with NPC. Therefore, lncRNAs may serve as potential prognostic factors in NPC.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive cancer most frequently detected at an advanced stage that limits treatment options to systemic chemotherapy, which has provided only marginal positive clinical outcomes. Currently, the first-line chemotherapeutic agent for PDAC is gemcitabine (GEM). However, the chemotherapy resistance to GEM is often overlooked in the clinical treatment of PDAC due to the lack of effective biological markers. Therefore, it is crucial to find new prognostic markers and therapeutic targets for patients with PDAC. In this study, we identified a novel regulatory mechanism in the development of resistance to GEM in PDAC. Here, we report that LINC01134 was significantly upregulated in primary tumors from PDAC patients. In vitro and in vivo functional studies revealed that LINC01134 promotes PDAC resistance to GEM through facilitating stem cell features and modulating the cell cycle. Mechanistically, LINC01134 interactes with tumor suppressor miR-497-5p in PDAC cells. Increased LINC01134 downregulates miR-140-3p to promotes the oncogenic WNT5A expression. Moreover, m6A demethylase FTO participated in the upregulation of LINC01134 by maintaining LINC01134 mRNA stability through YTHDF2. Taken together, the present study suggested FTO-mediated LINC01134 stabilization to promote chemotherapy resistance to GEM through miR-140-3p/WNT5A/WNT pathway in PDAC. Our study identified new prognostic markers and new therapeutic targets for patients with PDAC.
