Construction of ceRNA network mediated by circRNAs screening from microarray and identification of novel biomarkers for myasthenia gravis. Gene 2024; 918:148463. [PMID: 38631652 DOI: 10.1016/j.gene.2024.148463] [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: 12/19/2023] [Revised: 04/03/2024] [Accepted: 04/10/2024] [Indexed: 04/19/2024]
Abstract
BACKGROUND Recent studies have revealed that circRNA can serve as ceRNA to participate in multiple autoimmune diseases. Our study aims to explore the key circRNA as ceRNA and biomarker for MG. METHODS We used circRNA microarray to explore differentially expressed circRNAs (DECs) from MG and compare with control. Then, we predicted the target miRNA associated with DECs and screened miRNAs by the algorithm of random walk with restart (RWR). Next, we constructed the circRNA-miRNA-mRNA ceRNA regulated network (CMMC) to identify the hub objects. Following, we detected the expression of hub-circRNAs by RT-PCR. We verify has_circ_0004183 (circFRMD4) sponging miR-145-5p regulate cells proliferation using luciferase assay and CCK-8. RESULTS We found that the expression level of circFRMD4 and has_circ_0035381 (circPIGB) were upregulated and has_circ_0089153(circ NUP214) had the lowest expression level in MG. Finally, we proved circFRMD4 sponging miR-145-5p regulate Jurkat cells proliferation. CircFRMD4 take part in the genesis and development of MG via circFRMD4/miR145-5p axis. CONCLUSIONS We found that circFRMD4, circPIGB and circNUP214 can be considered as valuable potential novel biomarkers for AchR + MG. CircFRMD4 participate in the development of AchR + MG via targeting binding with miR-145-5p.

[PMID: 38061123 DOI: 10.1016/j.oraloncology.2023.106651] [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: 11/27/2023] [Accepted: 11/28/2023] [Indexed: 12/25/2023]
Abstract
BACKGROUND Ameloblastoma is characterized by aggressive nature, high recurrence rate, occasional malignant transformation, but recurrence and malignant incidence of ameloblastoma are not yet addressed by a large-scale case series study. MATERIALS AND METHODS This study provided a detailed description of the relationship between demographic characteristics and recurrence and malignant cases with different clinical types of ameloblastoma (n = 1626). RESULTS The overall incidence of recurrence and malignancy was 17.2 % and 3.4 %, respectively. Notably, we observed that there were multiple recurrent episodes (mean time, 24.3-28.7 months) among ameloblastoma patients. Multivariate analysis revealed that age of > 45 years (odds ratios (OR), 2.10; 95 % confidence interval (CI), 1.17-3.76), male (OR, 3.24; 95 %CI, 1.49-6.99), maxilla (OR, 5.58; 95 %CI, 3.11-10.0), and pre-existing recurrence (OR, 3.79; 95 %CI, 2.05-7.01) as independent factors were associated significantly with increased risk of malignancy. CONCLUSION Identification of the clinical factors responsible for increased risk of malignancy provides better insight in management planning for ameloblastoma.

Abstract
BACKGROUND Gastric cancer (GC) ranks fourth among the causes of death from malignant tumors in the world. Studies have implicated the dysregulation of circRNAs with GC. However, the relationship between hsa-circ-0052001 and GC is unclear. METHODS In our current study, we assessed the expression levels of hsa-circ-0052001 in GC cells and tissues using quantitative real-time PCR (qPCR). The role of hsa-circ-0052001 expression on the proliferation and invasion of GC cells was assessed using in vitro experiments. The role of hsa-circ-0052001 on the proliferation of GC cells was also analyzed using in vivo models. The pathways downstream of hsa-circ-0052001 were identified using bioinformatics analyses, western blot (WB) assays, and qRT-PCR. RESULTS We found that compared with normal gastric mucosa epithelial cells and adjacent paracancer tissues, hsa-circ-0052001 was overexpressed in GC cells and tissues. Also, the hsa-circ-0052001 level was linked to patient clinicopathological characteristics of GC. Cell proliferation and metastatic ability were inhibited in gastric cancer cells when hsa-circ-0052001 was knocked down in vitro and cancer growth in vivo. Mechanistically, hsa-circ-0052001 promoted the carcinogenesis of GC cells via the MAPK signal pathway. CONCLUSION Hsa-circ-0052001 functions as a tumor gene in promoting the progression of GC through MAPK pathway, which has provided a promising target for patients with GC.

Abstract
The role of circ_0089153 in breast cancer (BCa) malignancy development was explored. circ_0089153 expression in BCa was analyzed by Gene Expression Omnibus database. Clinical tissues were obtained from 90 BCa patients. Cell counting kit-8 assay, 5-ethnyl-2 deoxyuridine assay and colony formation experiment were applied for proliferation detection. Wound healing assay and Transwell experiment were used for migration and invasion detection. Dual luciferase reporter gene assay, RNA immunoprecipitation assay and RNA pull-down assay were conducted. In vivo growth and metastasis of BCa cells were performed. Quantitative real-time polymerase chain reaction, Western blot and immunohistochemistry were applied for RNAs and proteins expression. The up-modulated circ_0089153 indicated an unfavorable survival of BCa patients. circ_0089153 knockdown attenuated BCa cells proliferation, migration, invasion and epithelial-mesenchymal transition (EMT) (P < .01). circ_0089153 was miR-2467-3p sponge. Low miR-2467-3p expression indicated a worse survival of BCa patients. miR-2467-3p overexpression reduced BCa cells proliferation, migration, invasion and EMT (P < .05). circ_0089153 enhanced BCa cells proliferation, migration, invasion and EMT by sponging miR-2467-3p (P < .05). E2F6 was directly suppressed by miR-2467-3p. E2F6 high expression in BCa patients associated with worse survival. circ_0089153 knockdown suppressed in vivo BCa cells growth and lung metastasis (P < .01). circ_0089153 was an oncogene in breast cancer, which enhanced proliferation and metastasis through sponging miR-2467-3p/E2F6. circ_0089153 was suggested to be a potential target for BCa target treatment.

Abstract
In recent years, microRNAs (miRNAs) have attracted much attention because of their prominent role in cancer. An increasing number of studies have shown that miRNAs play an important role in a variety of tumors. miR-608 has been reported to be decreased in cancers, especially in solid tumors. miR-608 is regarded as a tumor suppressor, which has been verified through a large number of experiments both in vivo and in vitro. miR-608 participates in many biological processes, including cell proliferation, invasion, migration, and apoptosis, by inhibiting transmembrane proteins and many signaling pathways. Here, we summarize the expression profile and biological functions and mechanism of miR-608, suggesting that miR-608 is an ideal diagnostic and prognostic biomarker and a treatment target for cancer.

J Physiol Biochem 2022; 78:245-256.

Abstract
Abdominal aortic aneurysm (AAA) is a potentially fatal vascular disease, and the dysregulated circular RNAs (circRNAs) play key roles in AAA progression. Circ_0092291 was downregulated in AAA patients, but its function in AAA remains unclear. This research was performed for the functional analysis of circ_0092291 and its mechanism exploration with mircoRNA-626 (miR-626) and collagen type IV alpha1 chain (COL4A1) in AAA. Human aortic vascular smooth muscle cells (T/G HA-VSMC) were treated with angiotensin II (Ang II). Levels of circ_0092291, miR-626, and COL4A1 were determined using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Inflammatory cytokines were examined by enzyme-linked immunosorbent assay (ELISA). Cell apoptosis was measured using caspase3 activity assay and flow cytometry. Angiopoiesis was assessed via tube formation assay. The protein analysis was conducted by western blot. Dual-luciferase reporter assay, RNA immunoprecipitation (RIP), and RNA pull-down assays were used to validate the molecular binding. Circ_0092291 downregulation was found in AAA samples and Ang II-treated cells. Inflammatory response and cell apoptosis were reduced while angiopoiesis and ECM level were facilitated after overexpression of circ_0092291 in Ang II-treated T/G HA-VSMC cells. MiR-626 was a miRNA target for circ_0092291, and miR-626 inhibition protected T/G HA-VSMC from Ang II-induced cell injury. Moreover, the regulation of circ_0092291 was achieved by serving as a miR-626 sponge in Ang II-treated cells. COL4A1 was affirmed as a target for miR-626 and circ_0092291 resulted in the level change of COL4A1 by sponging miR-626. Additionally, miR-626 downregulation inhibited the cell damages caused by Ang II through increasing the level of COL4A1 and the function of circ_0092291 was attributed to the upregulation of COL4A1. The evidence indicated that circ_0092291 could suppress the Ang II-induced cell dysfunction by targeting the miR-626/COL4A1 signaling axis. Circ_0092291 might improve the diagnosis and treatment of AAA.Key Points.Biological mechanism, Apoptosis, Molecular target.
