[PMID: 38473915 DOI: 10.3390/ijms25052670] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 02/20/2024] [Accepted: 02/22/2024] [Indexed: 03/14/2024] Open
Abstract
Over the past century, molecular biology's focus has transitioned from proteins to DNA, and now to RNA. Once considered merely a genetic information carrier, RNA is now recognized as both a vital element in early cellular life and a regulator in complex organisms. Long noncoding RNAs (lncRNAs), which are over 200 bases long but do not code for proteins, play roles in gene expression regulation and signal transduction by inducing epigenetic changes or interacting with various proteins and RNAs. These interactions exhibit a range of functions in various cell types, including macrophages. Notably, some macrophage lncRNAs influence the activation of NF-κB, a crucial transcription factor governing immune and inflammatory responses. Macrophage NF-κB is instrumental in the progression of various pathological conditions including sepsis, atherosclerosis, cancer, autoimmune disorders, and hypersensitivity. It orchestrates gene expression related to immune responses, inflammation, cell survival, and proliferation. Consequently, its malfunction is a key contributor to the onset and development of these diseases. This review aims to summarize the function of lncRNAs in regulating NF-κB activity in macrophage activation and inflammation, with a particular emphasis on their relevance to human diseases and their potential as therapeutic targets. The insights gained from studies on macrophage lncRNAs, as discussed in this review, could provide valuable knowledge for the development of treatments for various pathological conditions involving macrophages.

Abstract
Periodontitis is an inflammatory disease characterized by the pathological loss of alveolar bone and the adjacent periodontal ligament. It is considered a disease that imposes a substantial health burden, with an incidence rate of 20-50%. The etiology of periodontitis is multifactorial, with genetic factors accounting for approximately half of severe cases. Studies have revealed that long non-coding RNAs (lncRNAs) play a pivotal role in periodontitis pathogenesis. Accumulating evidence suggests that lncRNAs have distinct regulatory mechanisms, enabling them to control numerous vital processes in periodontal cells, including osteogenic differentiation, inflammation, proliferation, apoptosis, and autophagy. In this review, we summarize the diverse roles of lncRNAs in the pathogenesis of periodontitis, shedding light on the underlying mechanisms of disease development. By highlighting the potential of lncRNAs as biomarkers and therapeutic targets, this review offers a new perspective on the diagnosis and treatment of periodontitis, paving the way for further investigation into the field of lncRNA-based therapeutics.

MicroRNA-874 targets phosphomevalonate kinase and inhibits cancer cell growth via the mevalonate pathway. Sci Rep 2022; 12:18443. [PMID: 36323841 PMCID: PMC9630378 DOI: 10.1038/s41598-022-23205-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 10/26/2022] [Indexed: 11/06/2022] Open
Abstract
The microRNA (miR) miR-874, a potential tumour suppressor, causes cell death via target gene suppression in various cancer types. Mevalonate pathway inhibition also causes cell death in breast cancer. However, the relationship between the mevalonate pathway and miR-874-induced apoptosis or its association with the tumour suppressor p53 has not been elucidated. We identified phosphomevalonate kinase (PMVK), a key mevalonate pathway enzyme, and sterol regulatory element-binding factor 2 (SREBF2), the master cholesterol biosynthesis regulator, as direct miR‑874 targets. Next-generation sequencing analysis revealed a significant miR-874-mediated downregulation of PMVK and SREBF2 gene expression and p53 pathway enrichment. Luciferase reporter assays showed that miR-874 directly regulated PMVK and SREBF2. miR-874-induced apoptosis was p53 dependent, and single-cell RNA sequencing analysis demonstrated that miR-874 transfection resulted in apoptosis and p53 pathway activation. Downregulation of PMVK expression also caused cell cycle arrest and p53 pathway activation, which was rescued by geranylgeranyl pyrophosphate (GGPP) supplementation. Analysis of The Cancer Genome Atlas (TCGA) database indicated a negative correlation between miR-874 and PMVK expression and between miR-874 and SREBF2 expression. These findings suggest that miR-874 suppresses the mevalonate pathway by targeting SREBF2 and PMVK, resulting in GGPP depletion, which activates the p53 pathway and promotes cycle arrest or apoptosis.

J Obstet Gynaecol Res 2022; 48:2594-2602. [PMID: 35817473 DOI: 10.1111/jog.15360] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 06/22/2022] [Accepted: 06/28/2022] [Indexed: 02/06/2023]
Abstract
BACKGROUND With the promotion of human papillomavirus (HPV) vaccine, cervical cancer has become a current research hotspot, and lncRNA has been confirmed to be used in the research of different diseases. This article systematically expounds the regulation and potential mechanisms of HOXA cluster antisense RNA 3 (HOXA-AS3) in cervical cancer, and discusses its possibility as a prognostic biomarker for cervical cancer. METHODS Relative expression levels of HOXA-AS3 and miR-29a-3p in tissues and cells were determined by real-time quantitative polymerase chain reaction (RT-qPCR). The survival of cervical cancer patients was analyzed by Kaplan-Meier method and the cumulative survival function table was drawn. The proliferation, migration, and invasion levels of HOXA-AS3 in cells were detected according to cell counting kit-8 (CCK-8) and transwell method. The dual-luciferase reporter gene assay confirmed the mechanism of action between HOXA-AS3 and miR-29a-3p. RESULTS HOXA-AS3 was elevated and miR-29a-3p was decreased in tissues and cells of cervical cancer patients. Knockdown of HOXA-AS3 could inhibit the progression of cervical cancer and was more conducive to patient survival. Bioinformatics analysis confirmed that HOXA-AS3 negatively regulates cervical cancer development by sponging miR-29a-3p. CONCLUSION In this research, knockdown of HOXA-AS3 could alleviate the process of cervical cancer by sponging miR-29a-3p, suggesting that HOXA-AS3 may be a potential prognostic target of cervical cancer, which could provide a theoretical basis for future clinical research of cervical cancer.

Abstract
Epigenetic factors are critical regulators of biological and pathological mechanisms and they could interact with different molecular pathways. Targeting epigenetic factors has been an idea approach in disease therapy, especially cancer. Accumulating evidence has highlighted function of long non-coding RNAs (lncRNAs) as epigenetic factors in cancer initiation and development and has focused on their association with downstream targets. microRNAs (miRNAs) are the most well-known targets of lncRNAs and present review focuses on lncRNA-miRNA axis in malignancy and therapy resistance of tumors. LncRNA-miRNA regulates cell death mechanisms such as apoptosis and autophagy in cancers. This axis affects tumor metastasis via regulating EMT and MMPs. Besides, lncRNA-miRNA axis determines sensitivity of tumor cells to chemotherapy, radiotherapy and immunotherapy. Based on the studies, lncRNAs can be affected by drugs and genetic tools in cancer therapy and this may affect expression level of miRNAs as their downstream targets, leading to cancer suppression/progression. LncRNAs have both tumor-promoting and tumor-suppressor functions in cancer and this unique function of lncRNAs has complicated their implication in tumor therapy. LncRNA-miRNA axis can also affect other signaling networks in cancer such as PI3K/Akt, STAT3, Wnt/β-catenin and EZH2 among others. Notably, lncRNA/miRNA axis can be considered as a signature for diagnosis and prognosis in cancers.

Abstract
AIM Increasing studies have revealed the participation of lncRNAs in the occurrence and development of cervical cancer. This study explored the influence of lncRNA LINC00649 in cervical cancer. METHODS Expression of LINC00649 and miR-216a-3p in cervical cancer was detected by reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR). The Kaplan-Meier curve and Cox regression analyses were conducted to evaluate the clinical value of LINC00649 in cervical cancer. The roles of LINC00649 in cervical cancer cells were detected by transfecting siRNA through cellular function assays. RESULTS LINC00649 expression was increased in cervical cancer tissues, especially in squamous histology, positive lymph node metastasis, and high-FIGO stage tissues. The higher expression of LINC00649 predicted a shorter survival rate for patients. LINC00649 could bind directly with miR-216a-3p. Silence of LINC00649 could enhance the expression of miR-216a-3p and suppress the cervical cancer cell proliferation abilities, migration capacities, and invasion power. Whereas, transfection of miR-216a-3p inhibitor partially reverses the above cellular activities changes in cervical cancer cells. CONCLUSIONS The LINC00649 expression may act as a prognostic predictor and may aggravate cervical cancer progression by targeting miR-216a-3p, providing potential therapeutic targets for patients with cervical cancer.

Abstract
miR-874 is located at 5q31.2, which is frequently deleted in cancer. miR-874 is downregulated in 22 types of cancers and aberrantly expressed in 18 types of non-cancer diseases. The dysfunction of miR-874 is not only closely related to the diagnosis and prognosis of tumor patients but also plays an important role in the efficacy of tumor chemotherapy drugs. miR-874 participates in the ceRNA network of long non-coding RNAs or circular RNAs, which is closely related to the occurrence and development of cancer and other non-cancer diseases. In addition, miR-874 is also involved in the regulation of multiple signaling pathways, including the Wnt/β-catenin signaling pathway, Hippo signaling pathway, PI3K/AKT signaling pathway, JAK/STAT signaling pathway, and Hedgehog signaling pathway. This review summarizes the molecular functions of miR-874 in the biological processes of tumor cell survival, apoptosis, differentiation, and tumorigenesis, and reveal the value of miR-874 as a cancer biomarker in tumor diagnosis and prognosis. Future work is necessary to explore the potential clinical application of miR-874 in chemotherapy resistance.

Abstract
Dysregulation of long noncoding RNA (lncRNA) is implicated in the initiation and progression of various tumors, including endometrial cancer (EC). However, the mechanism of lncRNAs in EC tumorigenesis and progression remains largely unexplored. In this work, we identified a novel lncRNA DC-STAMP domain-containing 1-antisense 1 (DCST1-AS1), which is highly upregulated and correlated with poor survival in EC patients. Overexpression of DCST1-AS1 significantly enhanced EC cell proliferation, colony formation, migration, and invasion in vitro and promoted tumor growth of EC in vivo. Mechanistically, DCST1-AS1 mediated EC progression by inducing the expression of homeobox B5 (HOXB5) and cell adhesion molecule 1 (CADM1), via acting as a competing endogenous RNA for microRNA-665 (miR-665) and microRNA-873-5p (miR-873-5p), respectively. In addition, we found that the expression of miR-665 and miR-873-5p was significantly downregulated, while HOXB5 and CADM1 expression levels were increased in EC tissues. Taken together, our findings support the important role of DCST1-AS1 in EC progression, and DCST1-AS1 may be used as a prognostic biomarker as well as a potential therapeutic target for EC.

Abstract
Purpose Long intergenic non-protein coding RNA 885 (LINC00885) has been well studied in breast cancer; however, its contribution in cervical cancer remains unclear. In this study, we aimed to determine the detailed functions of LINC00885 in cervical cancer and elucidate the underlying molecular regulation mechanism. Methods The expression status of LINC00885 in cervical cancer was determined using reverse transcription-quantitative polymerase chain reaction and by searching The Cancer Genome Atlas database. The detailed functions of LINC00885 in cervical cancer cells were confirmed using Cell Counting Kit 8 assay, flow cytometry analysis, Transwell cell migration and invasion assays, and tumor xenograft assay. Mechanistic experiments included bioinformatics prediction, RNA immunoprecipitation, luciferase reporter assay, and rescue experiments. Results LINC00885 was clearly overexpressed in cervical cancer, which was linked with unfavorable clinical outcomes. Functionally, LINC00885 deficiency suppressed cervical cancer cell proliferation, migration, and invasion but stimulated cell apoptosis in vitro. Furthermore, loss of LINC00885 restricted the growth of cervical cancer cells in vivo. Mechanistically, LINC00885 functioned as a competitive endogenous RNA for microRNA-432-5p (miR-432-5p) in cervical cancer. Furthermore, metastasis-associated colon cancer 1 (MACC1) was confirmed as the direct target of miR-432-5p, and LINC00885 could enhance MACC1 expression by sequestering miR-432-5p. Rescue experiments revealed that silencing of miR-432-5p or upregulation of MACC1 expression could effectively counteract the restrained aggressive properties of cervical cancer cells induced by LINC00885 deficiency. Conclusion LINC00885 upregulated MACC1 expression in cervical cancer cells by sponging miR-432-5p, thereby promoting cancer progression. The LINC00885/miR-432-5p/MACC1 pathway may help in the identification of potential prognostic biomarkers and therapeutic targets in cervical cancer.

Abstract
OBJECTIVE Emerging evidence has revealed that exosomal microRNAs (miRNAs) are implicated in human diseases. However, role of exosomal miR-125b-5p in sepsis-induced acute lung injury (ALI) remains further explored. We focused on the effect of exosomal miR-125b-5p on ALI progression via targeting topoisomerase II alpha (TOP2A). METHODS The ALI mouse models were established by cecal ligation and perforation, which were then treated with miR-125b-5p agomir or overexpressed TOP2A. Next, the pathological structure of ALI mouse lung tissues were observed, miR-125b-5p, TOP2A and vascular endothelial growth factor (VEGF) expression was determined, and the lung water content, inflammatory response, protein content in bronchoalveolar lavage fluid (BALF) and cell apoptosis in ALI mouse lung tissues were assessed. Exosomes were extracted from endothelial cells (ECs) and identified, which were then injected into the modeled mice to observe their roles in ALI. The targeting relationship between miR-125b-5p and TOP2A was confirmed. RESULTS MiR-125b-5p was downregulated while TOP2A was upregulated in ALI mice. MiR-125b-5p elevation or ECs-derived exosomes promoted VEGF expression, improved pathological changes and restrained lung water content, inflammatory response, protein content in BALF and cell apoptosis in lung tissues ALI mice. TOP2A overexpression reversed the repressive role of miR-125b-5p upregulation in ALI, while downregulated miR-125b-5p abrogated the effect of ECs-derived exosomes on ALI. TOP2A was confirmed as a direct target gene of miR-125b-5p. CONCLUSION Our study indicates that ECs-derived exosomes overexpressed miR-125b-5p to protect from sepsis-induced ALI by inhibiting TOP2A, which may contribute to ALI therapeutic strategies.
