[PMID: 37889059 PMCID: PMC10614065 DOI: 10.21873/cgp.20406] [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: 06/02/2023] [Revised: 07/22/2023] [Accepted: 08/04/2023] [Indexed: 10/28/2023] Open
Abstract
BACKGROUND/AIM Recent studies have demonstrated the crucial regulatory roles of circular RNAs (circRNAs) in cancer initiation and progression. The sponge mechanism of circRNAs has been shown to be widely active in various types of tumors. However, many circRNAs still have not been verified to function through this mechanism. This study aimed to investigate the regulatory mechanism of hsa_circ_0079557 in colorectal cancer (CRC) and its role in CRC progression. MATERIALS AND METHODS Raw gene expression profile datasets were downloaded from Gene Expression Omnibus (GEO) and combined to form a new dataset. Hsa_circ_0079557 was found to be highly expressed in CRC. Its role was evaluated in vitro and in vivo through a series of experiments, including quantitative real-time polymerase chain reaction (qRT-PCR), flow cytometry, colony formation, cell counting kit-8 (CCK-8), transwell assays, scratch wound healing assays, nude mice experiments, and immunohistochemistry (IHC). The association between hsa_circ_0079557 and the identified target microRNAs (miRNA) was confirmed through fluorescence in situ hybridization (FISH) and dual-luciferase reporter assays. The downstream target proteins were predicted using the web-based tool "TargetScan," and their expressions were determined using Western blot (WB). RESULTS Hsa_circ_0079557 was found to be relatively up-regulated in CRC tissues and cell lines. Suppression of hsa_circ_0079557 expression inhibited cell proliferation in vitro and in vivo. Additionally, hsa_circ_0079557 acted as a "molecular sponge" for miR-502-5p, up-regulating the expression of Cyclin D1 (CCND1). CONCLUSION In this study, we identify a highly expressed circRNA in CRC and propose a novel pathway of hsa_circ_0079557/miR-502-5p/CCND1 in CRC.

Zhou G, Ren L, Yin H, Liu J, Li X, Wang J, Li Y, Sang Y, Zhao Y, Zhou X, Sun Z. The alterations of miRNA and mRNA expression profile and their integration analysis induced by silica nanoparticles in spermatocyte cells. NANOIMPACT 2021; 23:100348. [PMID: 35559849 DOI: 10.1016/j.impact.2021.100348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Revised: 08/06/2021] [Accepted: 08/06/2021] [Indexed: 06/15/2023]
Abstract
Air pollution and the application of Silica nanoparticles (SiNPs) have increased the risk of human exposure to SiNPs. SiNPs are known to induce cytotoxicity in spermatocyte cells (GC-2spd cells) of mice and male reproductive system damage. However, the expression profiles of miRNA and mRNA and the molecular mechanism of miRNA-mRNA integration in reproductive toxicity induced by SiNPs in GC-2spd cells are still unclear. Therefore, GC-2spd cells were divided into 0 μg/mL and 5 μg/mL SiNPs groups, and the cells were collected and analyzed after passaging for 30 generations using miRNA microarray and Illumina high-throughput sequencing (Illumina HiSeq) for the integrated analysis of miRNA and mRNA expression. Both miRNA Microarray and Illumina Hiseq identified 15 significant differentially expressed miRNAs and 1648 significant differentially expressed mRNAs. Gene Ontology (GO) enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and miRNA-gene-pathway-network analysis revealed 15 significant differentially expressed miRNAs that could regulate the DNA replication and the fatty acid metabolism, respectively. Furthermore, the mRNA-mRNA regulatory network analysis revealed that Pkfl (phosphofructokinase, liver, B-type) and DHCR24 (24-dehydrocholesterol reductase) were highly expressed, but also affected DNA replication and fatty acid metabolism in SiNPs-treated GC-2spd cells. Additionally, miRNA-mRNA integration analysis revealed that miRNA-138-1-3p might have a regulatory relationship with fatty acid metabolism and DNA replication. It is confirmed that SiNPs could decrease the expression of 10 miRNAs and increase the expression of 5 miRNAs. These findings suggest that the cytotoxicity of GC-2spd cells induced by SiNPs depends on the deregulation of multiple miRNAs, which regulate the DNA replication and fatty acid metabolism. Our results are the first to establish an integrated analysis of miRNA-mRNA interactions and mRNA-mRNA and defines multiple pathways involved in SiNPs-treated GC-2spd cells.

Abstract
In order to identify new targets and treatment modalities for clear cell renal carcinoma, we surveyed the literature with respect to microRNAs involved in this disease. In this review, we have focused on up- and down-regulated miRs which mediate efficacy in preclinical clear-cell renal carcinoma-related in vivo models. We have identified 10 up-regulated and 33 down-regulated micro-RNAs according to this criterion. As proof-of-concept, micro-RNAs interfering with VEGF (miR-205p) and mTOR (mir-99a) pathways, which are modulated by approved drugs for this disease, have been identified. miRs targeting hypoxia induced factor-2α (HIF-2α) (miR-145), E3 ubiquitinylases speckle-type POZ protein (SPOP) (miR 520/372/373) and casitas B-lineage lymphoma (CBL) (miR-200a-3p), interfere with druggable targets. Further identified miRs interfere with cell-cycle dependent kinases, such as CDK2 (miR-200c), CDK4, 6 (miR-1) and CDK4, 9 (206c). Transmembrane receptor Ral interacting protein of 76 kD (RLIP76), targeted by mir-137, has emerged as another important target for ccRCC. Additional miRs and their targets merrying further preclinical validation are discussed.
