Lnc-PLA2G4A-4 facilitates the progression of hepatocellular carcinoma by inducing versican expression via sponging miR-23b-3p. Heliyon 2023; 9:e18698. [PMID: 37554815 PMCID: PMC10405012 DOI: 10.1016/j.heliyon.2023.e18698] [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: 04/25/2023] [Revised: 07/20/2023] [Accepted: 07/25/2023] [Indexed: 08/10/2023] Open
Abstract
Aberrant expression of long non-coding RNAs (lncRNAs) is associated with progression of multiple human cancers including hepatocellular carcinoma (HCC). However, the role of lncRNAs in HCC is not been fully understood. Our study aimed to investigate the biological function and potential molecular mechanism of Lnc-PAL2G4A-4 in HCC. In the current study, we show that Lnc-PLA2G4A-4 was significantly up-regulated in HCC tissues and high Lnc-PLA2G4A-4 expression was remarkably associated with tumor size, microvascular invasion and poor prognosis of HCC patients. Functionally, Lnc-PLA2G4A-4 positively regulated cell proliferation, invasion and migration in vitro, and facilitated lung metastasis of HCC in vivo. Mechanistically, Lnc-PLA2G4A-4 functioned as a competing endogenous RNA (ceRNA) to bind to miR-23b-3p and subsequently facilitate miR-23b-3p's target gene versican (VCAN) expression in HCC cells. Over-expression of miR-23b-3p could reverse Lnc-PLA2G4A-4 induced cell phenotypes in HCC and suppress versican expression of by rescue analysis. Collectively, Lnc-PLA2G4A-4 promotes HCC progression by targeting the miR-23b-3p/versican axis, which may be a potential biomarker and therapeutic target for HCC.

Xie H, Lu X. circNFATC3 facilitated the progression of oral squamous cell carcinoma via the miR-520h/LDHA axis. Open Med (Wars) 2023; 18:20230630. [PMID: 37398901 PMCID: PMC10308242 DOI: 10.1515/med-2023-0630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 11/16/2022] [Accepted: 01/05/2023] [Indexed: 07/04/2023] Open
Abstract
The aim of this study was to verify the effects of circular RNA nuclear factor of activated T-cells, cytoplasmic 3 (circNFATC3), in oral squamous cell carcinoma (OSCC) development. The levels of circNFATC3, microRNA-520h (miR-520h), and lactate dehydrogenase A (LDHA) were measured by qRT-PCR and western blot analysis. The cellular functions were assessed by using commercial kits, MTT assay, EdU assay, flow cytometry analysis, and transwell assay. The interactions between miR-520h and circNFATC3 or LDHA were confirmed by dual-luciferase reporter assay. Finally, the mice test was enforced to evaluate the character of circNFATC3. We observed that the contents of circNFATC3 and LDHA were upregulated and miR-520h levels were downregulated in OSCC tissues compared with those in paracancerous tissues. For functional analysis, circNFATC3 knockdown repressed the cell glycolysis metabolism, cell proliferation, migration, and invasion, although it improved cell apoptosis in OSCC cells. LDHA could regulate the development of OSCC. circNFATC3 acted as a miR-520h sponge to modulate LDHA expression. In addition, the absence of circNFATC3 subdued tumor growth in vivo. In conclusion, circNFATC3 promoted the advancement of OSCC by adjusting the miR-520h/LDHA axis.

Abstract
Background: Although mRNA vaccines have been effective against multiple cancers, their efficacy against stomach adenocarcinoma (STAD) remains undefined. Immunotyping can indicate the comprehensive immune status in tumors and their immune microenvironment, which is closely associated with therapeutic response and vaccination potential. The aim of this study was to identify potential antigens in STAD for mRNA vaccine development, and further distinguish immune subtypes of STAD to construct an immune landscape for selecting suitable patients for vaccination. Methods: The gene expression and clinicopathological features of patients with gastric cancer were downloaded from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression Program (GTEx). 729 samples from GSE66229 and GSE84437 were downloaded through GEO and were used as the validation cohorts. Differential gene expression, genetic alterations and prognosis were analyzed using the R package, cBioPortal program and Kaplan-Meier. The relationship between tumor antigens and immune cells was evaluated and plotted by TIMER. ConsensusClusterPlus was used for consistency matrix construction and data clustering, and graph learning-based dimensional reduction was used to depict immune landscape. WGCNA was used to estimate the relationship between the color modules and immune subtypes. Results: Two overexpressed and mutated tumor antigens associated with poor prognosis and infiltration of antigen presenting cells were identified in STAD, including RAI14 and NREP. The immune subtypes showed distinct molecular, cellular and clinical characteristics. IS1 and IS2 exhibited immune-activated phenotypes and correlated to better survival compared to IS3, while IS3 tumors was immunologically cold. Immunogenic cell death modulators, immune checkpoints, and CA125, and CEA were also differentially expressed among the three immune subtypes. Finally, the immune landscape of STAD showed a high degree of heterogeneity between individual patients. Conclusion: RAI14 and NREP are potential antigens for developing anti-STAD mRNA vaccine, and patients with IS1 and IS3 tumors may be suitable for vaccination.

Abstract
OBJECTIVE Specificity protein 1 (SP1), a transcription factor mediated by SUMOylation modifiers, is upregulated in gastric cancer (GC) and shares negative correlation with patient prognosis. Here, we paid main attention to the role of SP1 SUMOylation in the drug resistance of GC cells and the possible long non-coding RNA (lncRNA) SNHG17/microRNA-23b-3p (miR-23b-3p)/Notch2 network engaged in this process. METHODS Tumor tissues and non-tumor tissues were isolated from GC patients who received treatment with capecitabine and cisplatin (DDP). Co-immunoprecipitation was utilized to detect the SUMOylation level of SP1. Using gain- and loss-of-function approaches, we assessed the impacts of SNHG17/miR-23b-3p/Notch2 on sensitivity of DDP-resistant GC cells in vitro and in vivo. A series of assays such as luciferase activity detection and RNA pull-down were conducted for mechanistic exploration. RESULTS SP1 expression was increased due to low SP1 SUMOylation level in the recurrent GC tissues. This increase led to upregulated SNHG17 expression and SP1 binding sites existed in the SNHG17 promoter. In addition, SNHG17 could bind to miR-23b-3p while miR-23b-3p targeted Notch2. Loss of SNHG17 reduced the resistance of DDP-resistant GC cells to DDP, which was achieved through miR-23b-3p-dependent Notch2 inhibition. Finally, SP1 silencing attenuated the resistance of GC to DDP in mice. CONCLUSION Low SP1 SUMOylation induces SNHG17 upregulation and blocks miR-23b-3p-induced Notch2 inhibition, contributing to the resistance of GC to DDP. This study may aid in the development of therapeutic targets overcoming the chemoresistance of GC.

Carcinogenesis 2022; 43:682-692. [PMID: 35380635 DOI: 10.1093/carcin/bgac033] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 03/24/2022] [Accepted: 03/30/2022] [Indexed: 11/13/2022] Open
Abstract
MicroRNA(miR)-23b-3p is known to target various genes that are involved in cancer-related pathways. Exosomes are emerging intercellular communication agents. Exosomes secreted by cancer cells can deliver active molecules to the surrounding stromal cells, thereby influencing the recipient cells and promoting the development of cancers. However, the role of exosomal miR-23b-3p in salivary adenoid cystic carcinoma (SACC) is not yet clear. In this study, we set out to investigate the potential role of cancer-derived exosomal miR-23b-3p-related PTEN in the alteration of angiogenesis and vascular permeability in SACC. We investigated the effect of exosomal miR-23b-3p on the progression of SACC. In vitro experiments indicated that exosomal miR-23b-3p led to an up-regulation of vascular permeability, and reduced expression of tight junction proteins. In addition, exosomal miR-23b-3p also enhanced angiogenesis and migration. Next, the angiogenic effect of exosomal miR-23b-3p was validated in vivo, as it led to an increase in the tumor microvasculature. Furthermore, the growth rate of SACC was faster after injection of exosomes loaded with cholesterol- modified miR-23b-3p in mice. In conclusion, these results revealed that SACC cells-derived exosomes play an important role in promoting angiogenesis and local vascular microleakage of SACC by transporting miR-23b-3p, which suggests that miR-23b-3p in the exosomes may be a potential biomarker for distant metastasis of SACC. This suggests the potential of a novel therapeutic target by delivering anti-miR-23b-3p that focuses on exosomes.

Abstract
OBJECTIVE The expression of cytoskeleton-related protein γ-adducin (ADD3) was abnormally reduced in some tumors. Functional experiments demonstrated that it could inhibit the malignant progression of lung cancer and glioma, whereas the involvement of ADD3 in osteosarcoma was not clear. This study aimed to investigate the role of ADD3 in osteosarcoma and its upstream regulatory mechanisms. METHODS ADD3 was knocked down by siRNA transfection and the expression level of ADD3 was determined using quantitative real-time PCR assay and Western blot. CCK-8 assay and colony formation were performed to detect the capacity of cell proliferation. Transwell assay and PI and Annexin V-FITC staining were used to determine cell migration and apoptosis, respectively. Luciferase reporter experiment was performed to investigate the interaction between ADD3 and miR-23b-3p. RESULTS Based on gene silencing assays, we showed that knockdown of ADD3 suppressed apoptosis and promoted the proliferation and migration of osteosarcoma cells, revealing inhibitory effects of ADD3 in osteosarcoma. Luciferase reporter gene assays confirmed that miR-23b-3p could bind to the 3'-UTR of ADD3. Upregulation of miR-23b-3p not only inhibited the expression of ADD3, but also released the tumor suppressive role of ADD3 on the proliferation and migration of osteosarcoma cells. CONCLUSIONS Our study found that ADD3 functioned as a tumor suppressor gene during osteosarcoma development. The abnormal upregulation of miR-23b-3p targeted the expression of ADD3 and resulted in accelerated osteosarcoma cell proliferation and migration. Thus, the miR-23b-3p/ADD3 axis contributes to the development of osteosarcoma and ADD3 is a key driver of malignancy.
