Yang Y, Chen M, Lan R, Gong H. LINC01410 accelerates the invasion of trophoblast cells by modulating METTL3/Fas. Mol Biol Rep 2024; 51:895. [PMID: 39115693 PMCID: PMC11310249 DOI: 10.1007/s11033-024-09834-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2024] [Accepted: 07/30/2024] [Indexed: 08/11/2024]
Abstract
BACKGROUND Insufficient trophoblast invasion, culminating in suboptimal uterine spiral artery remodeling, is pinpointed as a pivotal contributor to preeclampsia (PE) development. LINC01410 has been documented to be increased in various neoplasms, and is significantly associated with the invasive capabilities of tumor cells. Nonetheless, its function and the mechanisms in the pathogenesis of PE require further investigation. METHODS AND RESULTS LINC01410 and methyltransferase-like 3 (METTL3) were ectopically expressed in HTR-8/Svneo cells via lentiviral transduction. Subsequently, the cells' invasive capabilities and apoptosis rates were evaluated employing Transwell assays and flow cytometry, respectively. The interplay between LINC01410 and METTL3, alongside the m6A methylation of FAS, was probed through RNA immunoprecipitation (RIP). Additionally, the association between FAS and METTL3 was elucidated via Coimmunoprecipitation (Co-IP) assays. The protein level of NF-κB, BAX, and BCL-2 in LINC01410-overexpressing cells was detected by Western blot. Our findings revealed that LINC01410 elevation increased the invasive ability of HTR-8/Svneo cells, directly impacting METTL3 then leading to its reduced expression. Conversely, heightened METTL3 expression mitigated invasiveness while enhancing apoptosis in these cells. Moreover, METTL3's interaction with FAS led to increased FAS expression, subject to m6A methylation. A surge in LINC01410 markedly decreased both mRNA and protein levels of FAS. Furthermore, LINC01410 overexpression significantly reduced NF-κB and BAX protein levels while augmenting BCL-2. CONCLUSIONS Upregulation of LINC01410 expression promotes trophoblast cell invasion by inhibiting FAS levels through modified m6A alteration and suppressing the NF-κB pathway. These findings underscore the pivotal role of LINC01410 in regulating trophoblast cell invasion and propose it as a promising therapeutic strategy for preventing or alleviating PE. This offers valuable insights for the clinical treatment of PE, for which definitive targeted therapy methods are currently lacking.

CANCER PATHOGENESIS AND THERAPY 2024; 2:142-154. [PMID: 39027151 PMCID: PMC11252520 DOI: 10.1016/j.cpt.2023.09.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 08/24/2023] [Accepted: 09/01/2023] [Indexed: 07/20/2024]
Abstract
Micro ribonucleic acids (miRNAs) are a highly conserved class of single-stranded non-coding RNAs. Within the miR-545/374a cluster, miR-545 resides in the intron of the long non-coding RNA (lncRNA) FTX on Xq13.2. The precursor form, pre-miR-545, is cleaved to generate two mature miRNAs, miR-545-3p and miR-545-5p. Remarkably, these two miRNAs exhibit distinct aberrant expression patterns in different cancers; however, their expression in colorectal cancer remains controversial. Notably, miR-545-3p is affected by 15 circular RNAs (circRNAs) and 10 long non-coding RNAs (lncRNAs), and it targets 27 protein-coding genes (PCGs) that participate in the regulation of four signaling pathways. In contrast, miR-545-5p is regulated by one circRNA and five lncRNAs, it targets six PCGs and contributes to the regulation of one signaling pathway. Both miR-545-3p and miR-545-5p affect crucial cellular behaviors, including cell cycle, proliferation, apoptosis, epithelial-mesenchymal transition, invasion, and migration. Although low miR-545-3p expression is associated with poor prognosis in three cancer types, studies on miR-545-5p are yet to be reported. miR-545-3p operates within a diverse range of regulatory networks, thereby augmenting the efficacy of cancer chemotherapy, radiotherapy, and immunotherapy. Conversely, miR-545-5p enhances immunotherapy efficacy by inhibiting T-cell immunoglobulin and mucin-domain containing-3 (TIM-3) expression. In summary, miR-545 holds immense potential as a cancer biomarker and therapeutic target. The aberrant expression and regulatory mechanisms of miR-545 in cancer warrant further investigation.

Abstract
Long noncoding RNAs (lncRNAs), which are more than 200 nucleotides in length and do not encode proteins, play crucial roles in governing gene expression at both the transcriptional and posttranscriptional levels. These molecules demonstrate specific expression patterns in various tissues and developmental stages, suggesting their involvement in numerous developmental processes and diseases, notably cancer. Despite their widespread acknowledgment and the growing enthusiasm surrounding their potential as diagnostic and prognostic biomarkers, the precise mechanisms through which lncRNAs function remain inadequately understood. A few lncRNAs have been studied in depth, providing valuable insights into their biological activities and suggesting emerging functional themes and mechanistic models. However, the extent to which the mammalian genome is transcribed into functional noncoding transcripts is still a matter of debate. This review synthesizes our current understanding of lncRNA biogenesis, their genomic contexts, and their multifaceted roles in tumorigenesis, highlighting their potential in cancer-targeted therapy. By exploring historical perspectives alongside recent breakthroughs, we aim to illuminate the diverse roles of lncRNA and reflect on the broader implications of their study for understanding genome evolution and function, as well as for advancing clinical applications.

Misexpression of LINC01410, FOSL1, and MAFB in peripheral blood mononuclear cells associated with diabetic nephropathy. Gene 2023; 862:147265. [PMID: 36764337 DOI: 10.1016/j.gene.2023.147265] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Revised: 01/23/2023] [Accepted: 02/06/2023] [Indexed: 02/11/2023]
Abstract
AIMS Currently, diabetic nephropathy (DN) is considered the leading cause of the end-stage renal disease (ESRD). However, its specific molecular mechanism is still unclear, and there is still a lack of effective diagnostic and therapeutic methods. METHOD A pathway was assumed after bioinformatics analysis of GEO datasets related to individuals with various levels of DN, LINC01410, MAFB, and FOSL1. Then, 46 patients with type 2 diabetes (T2DM) and different levels of albuminuria, and 12 individuals without diabetes, were selected. qPCR was performed to evaluate gene expression. One-way ANOVA followed by Tukey's -and linear trend tests were performed to analyze gene expression in different stages of the disease. Moreover, receiver operating characteristic (ROC) curves and the correlation between LINC01410, FOSL1, and MAFB were analyzed. RESULTS LINC01410, MAFB, and FOSL1 were selected based on bioinformatics analyses. The qPCR results showed that the expression of LINC01410 decreased, and FOSL1 and MAFB increased in micro-and macroalbuminuria groups compared to normoalbuminuria groups (P < 0.05). ROC curves demonstrated a significant diagnostic accuracy of LINC01410, MAFB, and FOSL1 between DN and participants with normoalbuminuria (P < 0.05). Pearson's correlation analysis revealed a positive association between the expressions of FOSL1 and MAFB (p = 0.01, r = 0.39). However, there was no correlation between LINC01410 with MAFB and FOSL1 (p = 0.23 and p = 0.21, respectively). CONCLUSION Dysregulation of LINC01410, MAFB, and FOSL1 is related to DN. These results may provide new insights into the role of LINC01410, MAFB, and FOSL1 as potential biomarkers in DN.

Abstract
According to World Health Organization (WHO), cancer is the leading cause of death for children and adolescents. Leukemias, brain cancers, lymphomas and solid tumors, such as neuroblastoma, ostesarcoma and Wilms tumors are the most common types of childhood cancers. Approximately 400,000 children and adolescents between the ages of 0 and 19 are diagnosed with cancer each year worldwide. The cancer incidence rates have been rising for the past few decades. Generally, the prognosis of childhood cancers is favorable, but the survival rate for many unresectable or recurring cancers is substantially worse. Although random genetic mutations, persistent infections, and environmental factors may serve as contributing factors for many pediatric malignancies, the underlying mechanisms are yet unknown. Long non-coding RNAs (lncRNAs) are a group of transcripts with longer than 200 nucleotides that lack the coding capacity. However, increasing evidence indicates that lncRNAs play vital regulatory roles in cancer initiation and development in both adults and children. In particular, many lncRNAs are stable in cancer patients' body fluids such as blood and urine, suggesting that they could be used as novel biomarkers. In support of this notion, lncRNAs have been identified in liquid biopsy samples from pediatric cancer patients. In this review, we look at the regulatory functions and underlying processes of lncRNAs in the initiation and progression of children cancer and discuss the potential of lncRNAs as biomarkers for early detection. We hope that this article will help researchers explore lncRNA functions and clinical applications in pediatric cancers.

Abstract
Renal cell carcinoma (RCC) originates from the epithelial cells of the renal tubules and has a high degree of malignancy and heterogeneity. Recent studies have found that exosomes regulate intercellular communication via transferring various bioactive molecules, such as circular RNAs (circRNAs), which are critical for cancer progression. However, the role of tumor cell-derived exosomal circRNAs in RCC remains unclear. In this study, we reported the high expression of circ-PRKCI in RCC tissues and serum exosomes. We also found that circ-PRKCI could be transferred exosomally from highly malignant RCC cells to relatively less malignant RCC cells. Tumor cell-derived exosomal circ-PRKCI promoted the proliferation, migration, and invasion of RCC cells, while inhibiting their apoptosis. Mechanistically, we found that circ-PRKCI promoted the proliferation of RCC via the miR-545-3p/CCND1 signaling pathway. Our study is the first to report the potential mechanisms of tumor cell-derived exosomal circ-PRKCI in RCC. In conclusion, this study will provide a new understanding about the molecular mechanisms of RCC progression.

Abstract
Background and purpose: Radioresistance remains a significant challenge in tumor therapy. This systematic review aims to demonstrate the role of long non-coding RNA (lncRNA) in cancer radioresistance/radiosensitivity. Material and methods: The electronic databases Pubmed, Embase, and Google Scholar were searched from January 2000 to December 2021 to identify studies addressing the mechanisms of lncRNAs in tumor radioresistance/sensitivity, each of which required both in vivo and in vitro experiments. Results: Among the 87 studies identified, lncRNAs were implicated in tumor radioresistance/sensitivity mainly in three paradigms. 1) lncRNAs act on microRNA (miRNA) by means of a sponge, and their downstream signals include some specific molecular biological processes (DNA repair and chromosome stabilization, mRNA or protein stabilization, cell cycle and proliferation, apoptosis-related pathways, autophagy-related pathways, epithelial-mesenchymal transition (EMT), cellular energy metabolism) and some signaling mediators (transcription factors, kinases, some important signal transduction pathways) that regulate various biological processes. 2) lncRNAs directly interact with proteins, affecting the cell cycle and autophagy to contribute to tumor radioresistance. 3) lncRNAs act like transcription factors to initiate downstream signaling pathways and participate in tumor radioresistance. Conclusion: lncRNAs are important regulators involved in tumor radioresistance\sensitivity. Different lncRNAs may participate in the radioresistance with the same regulatory paradigm, and the same lncRNAs may also participate in the radioresistance in different ways. Future research should focus more on comprehensively characterizing the mechanisms of lncRNAs in tumor radioresistance to help us identify corresponding novel biomarkers and develop new lncRNA-based methods to improve radioresistance.

Abstract
BACKGROUND Osteogenic differentiation of human bone marrow-derived mesenchymal stem cells (hBMSCs) is essential for bone formation, and its dysfunction is reported to be associated with osteoporosis (OP). Recent researches have determined that lncRNA PART1 participates in the pathogenesis of multiple diseases. However, its role in modulating osteogenic differentiation of hBMSCs is unclear. METHODS PART1, miR-185-5p, and RUNX3 levels were assessed via RT-qPCR. The protein levels of OCN, OSN, and COL1A1 were measured by western blotting. The osteoblastic phenotype was evaluated via ALP activity and ARS staining. The relationship between miR-185-5p and PART1 or RUNX3 was validated by luciferase reporter, RIP assays. RESULTS PART1 and RUNX3 expression were enhanced during hBMSC osteogenic differentiation. PART1 deletion decreased OCN, OSN, and COL1A1 levels and weakened ALP activity, but promoted the apoptosis of hBMSCs. Moreover, PART1 served as a ceRNA to influence the RUNX3 level via targeting miR-185-5p. In addition, RUNX3 was verified to activate the transcription of PART1 in hBMSCs. Finally, rescue assays indicated that suppression of miR-185-5p or addition of RUNX3 partially abolished the effects of PART1 knockdown on the levels of OCN, OSX, and COL1A1 levels, ALP activity, and apoptosis. CONCLUSION Our study elaborated that PART1/miR-185-5p/RUNX3 feedback contributed to osteogenic differentiation and inhibited the hBMSCs apoptosis, suggesting that PART1 might be a novel target for OP treatment.
