Abstract
Hepatocellular carcinoma (HCC) is a highly heterogeneous solid tumor, with its incidence showing a troubling upward trend over the past decade. Lenvatinib is one of the first-line medications for treating advanced HCC, however, the development of resistance significantly undermines its potential to improve patient prognosis. In recent years, exosomal circRNAs have been implicated in the resistance mechanisms of various cancers, yet their role in mediating lenvatinib resistance (LR) remains largely unexplored. In this study, we identified hsa_circ_0007132, which is upregulated in the serum exosomes of HCC patients exhibiting progressive disease (PD) following lenvatinib treatment. Subsequently, we employed LR cell lines to conduct both in vitro and in vivo experiments, which provided compelling evidence that hsa_circ_0007132 significantly promotes LR in HCC. Mechanistically, hsa_circ_0007132 interacts with the NONO protein, impairing its ubiquitination and leading to increased stability and upregulation of NONO expression, thereby enhancing NONO-mediated nuclear export of ZEB1 mRNA and elevating ZEB1 protein expression, which ultimately contributes to LR. In summary, our findings unveil a critical mechanism through which HCC mediates tumor progression and LR via exosomal hsa_circ_0007132, while also emphasizing that targeting NONO may represent a promising therapeutic strategy to overcome LR.
期刊介绍:
Non-coding RNA Research aims to publish high quality research and review articles on the mechanistic role of non-coding RNAs in all human diseases. This interdisciplinary journal will welcome research dealing with all aspects of non-coding RNAs-their biogenesis, regulation and role in disease progression. The focus of this journal will be to publish translational studies as well as well-designed basic studies with translational and clinical implications. The non-coding RNAs of particular interest will be microRNAs (miRNAs), small interfering RNAs (siRNAs), small nucleolar RNAs (snoRNAs), U-RNAs/small nuclear RNAs (snRNAs), exosomal/extracellular RNAs (exRNAs), Piwi-interacting RNAs (piRNAs) and long non-coding RNAs. Topics of interest will include, but not limited to: -Regulation of non-coding RNAs -Targets and regulatory functions of non-coding RNAs -Epigenetics and non-coding RNAs -Biological functions of non-coding RNAs -Non-coding RNAs as biomarkers -Non-coding RNA-based therapeutics -Prognostic value of non-coding RNAs -Pharmacological studies involving non-coding RNAs -Population based and epidemiological studies -Gene expression / proteomics / computational / pathway analysis-based studies on non-coding RNAs with functional validation -Novel strategies to manipulate non-coding RNAs expression and function -Clinical studies on evaluation of non-coding RNAs The journal will strive to disseminate cutting edge research, showcasing the ever-evolving importance of non-coding RNAs in modern day research and medicine.
