[PMID: 38604345 DOI: 10.1016/j.cellsig.2024.111171] [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: 12/26/2023] [Revised: 03/29/2024] [Accepted: 04/08/2024] [Indexed: 04/13/2024]
Abstract
BACKGROUND Psoriasis is a chronic, inflammatory skin disease. MicroRNAs (miRNAs) are an abundant class of non-coding RNA molecules. Recent studies have shown that multiple miRNAs are abnormally expressed in patients with psoriasis. The upregulation of miR-374a-5p has been associated with psoriasis severity. However, the specific role of miR-374a-5p in the pathogenesis of psoriasis remain unclear. METHODS qRT-PCR was employed to validate the expression of miR-374a-5p in psoriatic lesions and in a psoriasis-like cell model constructed using a mixture of M5 (IL-17A, IL-22, OSM, IL-1α, and TNF-α). HaCaT cells were transfected with miR-374a-5p mimic/inhibitor, and assays including EdU, CCK-8, and flow cytometry were conducted to evaluate the effect of miR-374a-5p on cell proliferation. The expression of inflammatory cytokines IL-1β, IL-6, IL-8, and TNF-α was verified by qRT-PCR. Bioinformatics analysis and dual-luciferase reporter gene assay were performed to detect the downstream target genes and upstream transcription factors of miR-374a-5p, followed by validation of their expression through qRT-PCR and Western blotting. A psoriasis-like mouse model was established using imiquimod cream topical application. The psoriasis area and severity index scoring, hematoxylin-eosin histology staining, and Ki67 immunohistochemistry were employed to validate the effect of miR-374a-5p on the psoriatic inflammation phenotype after intradermal injection of miR-374a-5p agomir/NC. Additionally, the expression of pathway-related molecules and inflammatory factors such as IL-1β, IL-17a, and TNF-α was verified by immunohistochemistry. RESULTS Upregulation of miR-374a-5p was observed in psoriatic lesions and the psoriasis-like cell model. In vitro experiments demonstrated that miR-374a-5p not only promoted the proliferation of HaCaT cells but also upregulated the expression of inflammatory cytokines, including IL-1β, IL-6, IL-8, and TNF-α. Furthermore, miR-374a-5p promoted skin inflammation and epidermal thickening in the Imiquimod-induced psoriasis-like mouse model. Mechanistic studies revealed that miR-374a-5p led to downregulation of WIF1, thereby activating the Wnt5a/NF-κB signaling pathway. The transcription factor p65 encoded by RELA, as a subunit of NF-κB, further upregulated the expression of miR-374a-5p upon activation. This positive feedback loop promoted keratinocyte proliferation and abnormal inflammation, thereby facilitating the development of psoriasis. CONCLUSION Our findings elucidate the role of miR-374a-5p upregulation in the pathogenesis of psoriasis through inhibition of WIF1 and activation of the Wnt5a/NF-κB pathway, providing new potential therapeutic targets for psoriasis.

Targeting the Wnt/β-catenin cascade in osteosarcoma: The potential of ncRNAs as biomarkers and therapeutics. Pathol Res Pract 2024; 259:155346. [PMID: 38781762 DOI: 10.1016/j.prp.2024.155346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2024] [Revised: 04/26/2024] [Accepted: 05/09/2024] [Indexed: 05/25/2024]
Abstract
Osteosarcoma (OS) is a bone cancer which stems from several sources and presents with diverse clinical features, making evaluation and treatment difficult. Chemotherapy tolerance and restricted treatment regimens hinder progress in survival rates, requiring new and creative therapeutic strategies. The Wnt/β-catenin system has been recognised as an essential driver of OS development, providing potential avenues for therapy. Non-coding RNAs (ncRNAs), such as circular RNAs (circRNAs), long non-coding RNAs (lncRNAs), and microRNAs (miRNAs), are essential in modulating the Wnt/β-catenin cascade in OS. MiRNAs control the system by targeting vital elements, while lncRNAs and circRNAs interact with system genes, impacting OS growth and advancement. This paper thoroughly analyses the intricate interplay between ncRNAs and the Wnt/β-catenin cascade in OS. We examine how uncontrolled levels of miRNAs, lncRNAs, and circRNAs lead to an abnormal Wnt/β-catenin network, which elevates the development, spread, and susceptibility to the treatment of OS. We emphasise the potential of ncRNAs as diagnostic indicators and avenues for treatment in OS care. The review offers valuable insights for academics and clinicians studying OS aetiology and creating new treatment techniques for the ncRNA-Wnt/β-catenin cascade. Utilising the oversight roles of ncRNAs in the Wnt/β-catenin system shows potential for enhancing the outcomes of patients and progressing precision medicine in OS therapy.

miR‑29a‑3p inhibits the malignant characteristics of non‑small cell lung cancer cells by reducing the activity of the Wnt/β‑catenin signaling pathway. Oncol Lett 2022; 24:379. [PMID: 36238844 PMCID: PMC9494602 DOI: 10.3892/ol.2022.13499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Accepted: 08/18/2022] [Indexed: 12/03/2022] Open
Abstract
MicroRNAs (miRNAs) can influence non-small cell lung cancer (NSCLC) in a tumor-suppressive and oncogenic manner. The present study aimed to investigate the effects and underlying mechanisms of miR-29a-3p in NSCLC. NSCLC cell lines (A549, H1299, and H460) and a normal lung epithelial cell line (BEAS-2B) were used. Additionally, a mouse lung tumor xenograft model was established using A549 cells and used to determine the effects of miR-29a-3p on NSCLC in vivo. Tumor volumes were measured every week. The expression of miR-29a-3p in cells and lung tissues were detected by RT-qPCR. Cell proliferation was detected using Cell Counting Kit-8 and EdU assays. Migration and invasion were assessed using wound healing and Transwell invasion assays, respectively. Ki-67 expression was detected using immunohistochemical staining. The expression levels of Wnt3a and β-catenin were determined using western blotting. miR-29a-3p expression was significantly downregulated in NSCLC cells and mice. In contrast to miR-29a-3p knockdown, miR-29a-3p overexpression decreased NSCLC cell proliferation, migration, and invasion as well as tumor growth in in the NSCLC mouse model. Moreover, miR-29a-3p overexpression decreased the protein expression levels of Wnt3a and β-catenin. The inhibitory effects of miR-29a-3p on NSCLC cells were reversed by LiCl (an activator of the Wnt signaling pathway). In conclusion, miR-29a-3p prevented NSCLC tumor growth and cell proliferation, migration, and invasion by inhibiting the Wnt/β-catenin signaling pathway. This finding offers novel insights into the prognosis and treatment of NSCLC.

Biochem Pharmacol 2021; 193:114758. [PMID: 34481813 DOI: 10.1016/j.bcp.2021.114758] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 08/24/2021] [Accepted: 08/31/2021] [Indexed: 12/13/2022]
Abstract
Osteosarcoma (OS) is an adolescent and young adult malignancy that mostly occurs in long bones. The treatment of OS is still a big challenge for clinicians due to increasing chemoresistance, and many efforts are being made today to find more beneficial treatments. In this regard, the use of microRNAs has shown a high capacity to develop promising therapies. By targeting cancer-involved signaling pathways, microRNAs reduce the cellular level of these protein pathways; thereby reducing the growth and invasion of tumors, and even leading cancer cells to apoptosis. One of these oncogenic pathways that play an important role in OS development and can be targeted by microRNAs is the Wnt/β-catenin signaling pathway. Hence, the first goal of this review article is to explain the cross-talk of microRNAs and the Wnt/β-catenin signaling in OS and then discussing recent findings of the use of microRNAs as a therapeutic approach in OS.

Abstract
Accumulating researches indicate that long non-coding RNAs (lncRNAs) participate in human bone mesenchymal stem cells (hBMSCs) osteogenic differentiation. The present study aimed to investigate the underlying molecular mechanisms of long intergenic non-protein coding RNA 899 (LINC00899) in osteoporosis. Therefore, reverse transcription-quantitative PCR was performed to evaluate the expression levels of LINC00899, microRNA (miR)-374a and runt-related transcription factor 2 (RUNX2) in clinical tissues and hBMSCs. The potential interaction between miR-374a and LINC00899 or RUNX2 was predicted utilizing the StarBase software and verified by luciferase reporter and RNA binding protein immunoprecipitation assays. In addition, alkaline phosphatase activity and Alizarin Red S staining were used to evaluate the osteogenic potential of hBMSCs. The results showed that the expression levels of LINC00899 were gradually increased, whilst those of miR-374a were decreased as the osteogenic induction process progresses. Additionally, the expression of LINC00899 was downregulated in the bone tissues of patients with osteoporosis, where LINC00899 knockdown reduced the expression levels of osteogenesis-related genes osteocalcin (OCN), osteopontin (OPN) and RUNX2 in hBMSCs. LINC00899 was also found to directly target miR-374a, thereby inhibiting its expression. Finally, it was predicted that RUNX2 could be directly targeted by miR-374a, such that miR-374a silencing partially abolished the inhibitory effect of LINC00899 knockdown on the expression of RUNX2, OPN and OCN. Overall, findings of the present study suggested that LINC00899 could facilitate the osteogenic differentiation of hBMSCs and prevent osteoporosis by sponging miR-374a to enhance the expression of RUNX2, which provide a potentially useful therapeutic strategy for patients with osteoporosis.

Abstract
Osteosarcoma (OS) is the most common type of primary bone tumor in children and adults. Dangshen (Codonopsis pilosula) is a traditional Chinese medicine commonly used in the treatment of OS worldwide. However, the molecular mechanisms of Dangshen in OS remain unclear. Hence, in this study, we aimed to systematically explore the underlying mechanisms of Dangshen in the treatment of OS. Our study adopted a network pharmacology approach, focusing on the identification of active ingredients, drug target prediction, gene collection, gene ontology (GO) enrichment, Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment, and other network tools. The network analysis identified 15 active compounds in Dangshen that were linked to 48 possible therapeutic targets related to OS. The results of the gene enrichment analysis show that Dangshen produces a therapeutic effect in OS likely by regulating multiple pathways associated with DNA damage, cell proliferation, apoptosis, invasion, and migration. Based on the network pharmacology approach, we successfully predicted the active compounds and their respective targets. In addition, we illustrated the molecular mechanisms that mediate the therapeutic effect of Dangshen in OS. These findings may aid in the development of novel targeted therapies for OS in the future.

Abstract
Background Cancer is a disease of abnormal cell proliferation caused by abnormal expression of cancer-related genes. However, it is still difficult to distinguish benign and malignant lesions in many cases. KIF4A has been reported to be associated with a variety of cancer lesions. We aimed to explore whether KIF4A could be used as a biomarker of pan-cancer diagnostic. Methods We identified twenty-eight cell cycle-related genes that were overexpressed in no less than ten types of cancer. We determined KIF4A mRNA and protein expression in osteosarcoma (OS) cells. Furthermore, to determine the effect of KIF4A in OS, we silenced KIF4A in OS cells and detected cell viability, colony formation, invasion, migration, apoptosis and cell cycle parameters. Results KIF4A exhibited upregulated expression in eleven types of cancer. Cell cycle-related genes are extensively overexpressed in various types of cancers. KIF4A overexpression can serve as a diagnostic and prognostic marker in various cancers. Silencing KIF4A inhibited the viability, colony formation, invasion and migration and induced apoptosis and cell cycle arrest of OS cells. Our findings revealed that high expression of KIF4A could serve as a diagnostic and prognostic marker in OS cancers. Conclusion KIF4A could serve as a pan-cancer diagnostic and prognostic marker. KIF4A could be used as a novel therapeutic target for OS.

Abstract
Recently, many mircroRNAs (miRNAs) involved in the development and progression of cancer have been reported to regulate cell growth and metastasis, including microRNA-202 (miR-202). The purpose of the present study was to elucidate the effect of miR-202 on endometrial carcinoma (EC) cell migration and invasion. First, qRT-PCR showed that miR-202 was down-regulated in EC tissues, which was associated with poor prognosis in EC patients. Functionally, transwell assay indicated that miR-202 inhibited cell migration and invasion in EC cells. In addition, miR-202 also blocked epithelial-mesenchymal transition (EMT) through suppressing N-cadherin and Vimentin expressions and promoting E-cadherin expression. Moreover, the dual-luciferase reporter assay showed that fibroblast growth factor 2 (FGF2) is a direct target gene for miR-202 in EC cells. Furthermore, up-regulation of FGF2 attenuated the inhibitory effect of miR-202 on cell migration and invasion in EC. Besides that, miR-202 inactivated the Wnt/β-catenin signaling by suppressing β-catenin expression in EC. In conclusion, miR-202 inhibited cell migration and invasion by targeting FGF2 and inactivating the Wnt/β-catenin signaling in EC.

Abstract
Recently, microRNAs (miRNAs) receive more attention due to their role in the pathogenesis of malignancies. Retinoblastoma (RB) is the most serious and harmful malignant tumor in infants and young children with eye diseases, which often endangers the lives of children. This study was designed to determine how miR-598 is involved in RB progression. In this study, quantitative reverse transcription-polymerase chain reaction, Western blot, dual-luciferase reporter, Cell Counting Kit-8, and Transwell assays were adopted to detect miR-598 expression and function in RB. The decreased expression of miR-598 was identified in RB. Overexpression of miR-598 suppressed the viability and metastasis of RB cells. Further, E2F transcription factor 1 (E2F1) is verified as a direct target of miR-598. Furthermore, E2F1 recovered miR-598-mediated-inhibition of cell viability and metastasis in RB. In addition, miR-598 was found to promote cell apoptosis and inactivate the protein kinase B (AKT) pathway in RB. miR-598 suppressed RB cell viability and metastasis through inhibiting E2F1 and inactivating AKT pathway, which may provide a new perspective for RB treatment.

Abstract
Osteosarcoma (OS) mortality rate is increasing. Various microRNAs (miRNAs) have been investigated in the pathological process of OS except for miR-744. Hence, this research was designed to explore miR-744 function in OS. RT-qPCR and western blot analysis were used to quantify miR-744 and large tumor suppressor kinase 2 (LATS2) expression levels. The function of miR-744 was investigated using MTT and Transwell assays. Target gene of miR-744 was verified by dual-luciferase reporter assay. miR-744 expression was increased in OS, which was associated with worse clinical features and prognosis of OS patients. Importantly, miR-744 promoted cell viability and metastasis in OS. Furthermore, miR-744 induced Wnt/β-catenin pathway and epithelial-mesenchymal transition (EMT) in OS. In addition, miR-744 directly targeted LATS2 and blocked its expression in OS. Moreover, upregulation of LATS2 weakened the promotion of cell viability and metastasis induced by miR-744 in OS. In conclusion, miR-744 accelerated OS progression through restraining LATS2 and activating Wnt/β-catenin pathway and EMT.
