Xu Z, Zheng L, Li S. Paclitaxel-induced inhibition of NSCLC invasion and migration via RBFOX3-mediated circIGF1R biogenesis. Sci Rep 2024; 14:774. [PMID: 38191906 PMCID: PMC10774373 DOI: 10.1038/s41598-024-51500-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Accepted: 01/05/2024] [Indexed: 01/10/2024] Open
Abstract
We previously reported that circIGF1R is significantly downregulated in non-small cell lung cancer (NSCLC) cells and tissues. It inhibits cancer cell invasion and migration, although the underlying molecular mechanisms remain elusive. The invasion and migration of NSCLC cells was analyzed by routine in vivo and in vitro functional assays. Fluorescent in situ hybridization, luciferase reporter assay, RNA pull-down assay and RNA immunoprecipitation (RIP) assay were performed to explore the molecular mechanisms. Mechanism of action of paclitaxel-induced RBFOX3-mediated inhibition of NSCLC invasion and migration was investigated through in vitro and in vivo experiments.Our study reveals that circIGF1R acts as a Competing Endogenous RNA (ceRNA) for miR-1270, thereby regulating Van-Gogh-like 2 (VANGL2) expression and subsequently inhibiting NSCLC cell invasion and migration via the Wnt pathway. We also found that RNA binding protein fox-1 homolog 3 (RBFOX3) enhances circIGF1R biogenesis by binding to IGF1R pre-mRNA, which in turn suppresses migration and invasion in NSCLC cells. Additionally, the chemotherapeutic drug paclitaxel was shown to impede NSCLC invasion and migration by inducing RBFOX3-mediated circIGF1R biogenesis.RBFOX3 inhibits the invasion and migration of NSCLC cells through the circIGF1R/ miR-1270/VANGL2 axis, circIGF1R has the potential to serve as a biomarker and therapeutic target for NSCLC.

Abstract
Circular RNAs (CircRNAs) are reported to exert vital regulatory roles in the occurrence and development of various human malignancies, including non-small cell lung cancer (NSCLC). Bioinformatics methods identified the down-regulation of circSCN8A (circBase ID: hsa_circ_0026337) in NSCLC tissues. However, its biological functions and molecular mechanisms in NSCLC remain unknown. In this study, we found that circSCN8A expression was down-regulated in NSCLC tissues and cells. Low circSCN8A expression was positively associated with aggressive clinicopathological characteristics and poor prognosis in NSCLC patients. CircSCN8A suppressed cell proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) in vitro and blocked tumor growth in vivo. Moreover, circSCN8A promoted cell ferroptosis in NSCLC. Mechanistically, circSCN8A acted as a competing endogenous RNA (ceRNA) by sponging miR-1290 to enhance the expression of long-chain acyl-CoA synthetase-4 (ACSL4). Furthermore, the knockdown of ACSL4 or overexpression of miR-1290 reversed the effect of circSCN8A on facilitating ferroptosis and inhibiting cell proliferation and metastasis. In summary, circSCN8A represses cell proliferation and metastasis in NSCLC by regulating the miR-1290/ACSL4 axis to induce ferroptosis. Thus, circSCN8A may represent a promising therapeutic target against NSCLC.

Abstract
Lung cancer is one of the most common malignant tumor types and the leading cause of cancer‑associated death worldwide. Different types of lung cancer exhibit differences in terms of pathophysiology and pathogenesis, and also treatment and prognosis. Accumulating evidence has indicated that circular RNAs (circRNAs) are abnormally expressed among different types of lung cancer and confer important biological functions in progression and prognosis. However, studies comparing different circRNAs in lung cancer subtypes are scarce. Furthermore, circRNAs have an important role in drug resistance and are related to clinicopathological features in lung cancer. Summaries of the association of circRNAs with drug resistance are also scarce in the literature. The present study outlined the biological functions of circRNAs and focused on discriminating differential circRNA patterns and mechanisms in three different types of lung cancer. The emerging roles of circRNAs in the resistance to chemotherapy, targeted therapy, radiotherapy and immunotherapy were also highlighted. Understanding these aspects of circRNAs sheds light on novel physiological and pathophysiological processes of lung cancer and suggests the application of circRNAs as biomarkers for diagnosis and prognosis, as well as therapeutic resistance.

Abstract
The lung microbiome plays an essential role in maintaining healthy lung function, including host immune homeostasis. Lung microbial dysbiosis or disruption of the gut-lung axis can contribute to lung carcinogenesis by causing DNA damage, inducing genomic instability, or altering the host's susceptibility to carcinogenic insults. Thus far, most studies have reported the association of microbial composition in lung cancer. Mechanistic studies describing host-microbe interactions in promoting lung carcinogenesis are limited. Considering cancer as a multifaceted disease where epigenetic dysregulation plays a critical role, epigenetic modifying potentials of microbial metabolites and toxins and their roles in lung tumorigenesis are not well studied. The current review explains microbial dysbiosis and epigenetic aberrations in lung cancer and potential therapeutic opportunities.

Abstract
Objectives: Epidermal growth factor receptor-tyrosine kinase
inhibitors are widely used for lung epidermal growth factor receptor-positive
lung adenocarcinomas, but acquired resistance is inevitable. Although non-coding
RNAs, such as circular RNA and microRNA, are known to play vital roles in
epidermal growth factor receptor-tyrosine kinase inhibitor resistance,
comprehensive analysis is lacking. Thus, this study aimed to explore the
circular RNA-microRNA-messenger RNA regulatory network involved in epidermal
growth factor receptor-tyrosine kinase inhibitor resistance.
Methods: To identify differentially expressed genes between the
epidermal growth factor receptor-tyrosine kinase inhibitor sensitive cell line
PC9 and resistant cell line PC9/ epidermal growth factor receptor-tyrosine
kinase inhibitor resistance(PC9/ER), circular RNA, microRNA and messenger RNA
microarrays were performed. Candidates were then identified to construct a
circular RNA-microRNA-messenger RNA network using bioinformatics. Additionally,
Gene Oncology and Kyoto Encyclopedia of Genes and Genomes pathway analyses were
conducted to evaluate the network messenger RNA, setting up a protein-protein
interaction network for hub-gene identification. Afterwards, RNA
immunoprecipitation was performed to enrich microRNA, and quantitative real-time
PCR was used to estimated gene expression levels. Results: In
total, 603, 377, and 1863 differentially expressed circular RNA, microRNA,
messenger RNAs, respectively, were identified using microarray analysis,
constructing a circular RNA-microRNA-messenger RNA network containing 18
circular RNAs, 17 microRNAs and 175 messenger RNAs. Moreover, Gene Oncology and
Kyoto Encyclopedia of Genes and Genomes pathway analyses showed that the most
enriched biological process terms and pathways were related to epidermal growth
factor receptor-tyrosine kinase inhibitor resistance, including Wnt and Hippo
signaling pathways. Based on the competing endogenous RNA and protein-protein
interaction network, circ-0007312 was showed to interact with miR-764 and both
circ-0003748 and circ-0001398 were shown to interact with miR-628; both these
microRNAs targeted MAPK1. Furthermore, circ-0007312, circ-0003748, circ-0001398,
and MAPK1 were up-regulated, whereas miR-764 and miR-628 were downregulated in
PC9/ER cells as compared to parental PC9 cells. We also found that circ-0007312
and miR-764 were positively expressed in plasma. Conclusions: Our
original study associated with mechanism of target therapy in lung cancer
provided a systematic and comprehensive regulation of circular RNA, microRNA and
messenger RNA in epidermal growth factor receptor-tyrosine kinase inhibitor
resistance. It was found that circ-0007312- miR-764-MAPK1,
circ-0003748-miR-628-MAPK1, and circ-0001398-miR-628-MAPK1 axis may play key
roles in epidermal growth factor receptor-tyrosine kinase inhibitor
resistance.
