Exosomes encompass a great deal of valuable biological information and play a critical role in tumor development. However, the mechanism of exosomal lncRNAs remains poorly elucidated in bladder cancer (BCa). In this study, we identified exosomal lnc-TAF12–2:1 as a novel biomarker in BCa diagnosis and aimed to investigate the underlying biological function. Dual luciferase reporter assay, RNA immunoprecipitation (RIP), RNA pulldown assays, and xenograft mouse model were used to verify the competitive endogenous RNA mechanism of lnc-TAF12–2:1. We found exosomal lnc-TAF12–2:1 up-regulated in urinary exosomes, tumor tissues of patients, and BCa cells. Down-regulation of lnc-TAF12–2:1 impaired BCa cell proliferation and migration, and promoted cell cycle arrest at the G0/G1 phase and cell apoptosis. The opposite effects were also observed when lnc-TAF12–2:1 was overexpressed. lnc-TAF12–2:1 was transferred by intercellular exosomes to modulate malignant biological behavior. Mechanistically, lnc-TAF12–2:1 packaged in the exosomes relieved the miRNA-mediated silence effect on ASB12 via serving as a sponger of miR-7847–3p to accelerate progression in BCa. ASB12 was also first proved as an oncogene to promote cell proliferation and migration and depress cell cycle arrest and cell apoptosis in our data. In conclusion, exosomal lnc-TAF12–2:1, located in the cytoplasm of BCa, might act as a competitive endogenous RNA to competitively bind to miR-7847–3p, and then be involved in miR-7847–3p/ASB12 regulatory axis to promote tumorigenesis, which provided a deeper insight into the molecular mechanism of BCa.

RNA-binding proteins (RBPs) regulate the generation of circular RNAs (circRNAs) by participating in the reverse splicing of circRNA and thereby influencing circRNA function in cells and diseases, including cancer. Increasing evidence has demonstrated that the circRNA-RBP network plays a complex and multifaceted role in tumor progression. Thus, a better understanding of this network may provide new insights for the discovery of cancer drugs. In this review, we discuss the characteristics of RBPs and circRNAs and how the circRNA-RBP network regulates tumor cell phenotypes such as proliferation, metastasis, apoptosis, metabolism, immunity, drug resistance, and the tumor environment. Moreover, we investigate the factors that influence circRNA-RBP interactions and the regulation of downstream pathways related to tumor development, such as the tumor microenvironment and N6-methyladenosine modification. Furthermore, we discuss new ideas for targeting circRNA-RBP interactions using various RNA technologies.

Isoleucyl-tRNA synthetase 2 (IARS2), originally regarded as an enzyme ligating isoleucine to the corresponding tRNA, has been identified as an oncogene recently. However, its function in pancreatic ductal adenocarcinoma (PDAC) remains to be discovered. Here we explored the biological role of IARS2 in PDAC. Up-regulated IARS2 was found in PDAC tissues and cell lines. Kaplan-Meier survival analysis indicated a worse prognosis in patients with high IARS2 expression. CCK-8, EdU, and colony formation assays showed IARS2 overexpression enhanced PDAC proliferation, which was reduced by IARS2 knockdown. Meanwhile, IARS2 down-regulation inhibited PDAC metastasis by impeding epithelial–mesenchymal transition. These results were also supported by subcutaneous xenograft and metastasis assays . To figure out underlying mechanisms, differential and enrichment analyses were conducted and the WNT signaling pathway was discovered. Our results demonstrated that there was no significant relationship between the WNT signaling pathway key factor CTNNB1 and IARS2 at the transcription level. However, cycloheximide assays showed that IARS2 reduced the β-catenin degradation rate. IARS2 inhibited the phosphorylation of β-catenin at the Ser33/37 site and regulated downstream targets of WNT signaling including c-MYC, c-JUN, and MMP7. The enhancement of proliferation and metastasis caused by IARS2 could be reversed by MSAB, an agent that promotes β-catenin degradation. In summary, IARS2 facilitates PDAC proliferation and metastasis by stabilizing β-catenin, which leads to WNT/β-catenin activation. IARS2 serves as an underlying prognosis marker and a potential therapeutic target for PDAC.
