Background: More and more evidence showed that circRNA/miRNA/mRNA axis played a vital role in the pathogenesis of some diseases. However, the role of circRNA/miRNA/mRNA axis in partial bladder outlet obstruction (pBOO) remains unknown. Our study aimed to explore the complex regulatory mechanism of circRNA/miRNA/mRNA axis in pBOO.
Methods: The pBOO rat model was established, and the bladder tissues were collected for mRNA sequencing. The differentially expressed mRNAs were analyzed by high-throughput sequencing, and the GO and KEGG analysis of the differentially expressed mRNAs were performed. Competing endogenous RNAs (ceRNAs) analysis identified the potential regulation function of circRNA/miRNA/mRNA axis in pBOO. qRT-PCR detected the expression of circRNA/miRNA/mRNA. miRanda software was performed to predict the relationship between circRNA and miRNA, miRNA and mRNA.
Results: Compared with the sham group, a total of 571 mRNAs were differentially expressed in the pBOO group, of which 286 were up-regulated and 285 were down-regulated. GO analysis showed that the mRNAs were mainly involved in cellular process, single-organism process, and cell, etc. KEGG analysis showed that the enriched signaling pathways were metabolic pathways, cell adhesion molecules (CAMs), and HTLV-I infection, etc. Based on the previous transcriptome data and differentially expressed circRNAs, we drew the ceRNA network regulation diagram. qRT-PCR results confirmed that chr3:113195876|113197193/rno-miR-30c-1-3p/Gata4, chr1:126188351|126195625/rno-miR-153-5p/Diaph3, and chr9:81258380|81275269/rno-miR-135b-5p/Pigr axis may have ceRNA function. miRanda confirmed there have the binding sites of circRNA/miRNA/mRNA axis.
Conclusions: CircRNA/miRNA/mRNA axis was involved in the progression of pBOO. Our research on the circRNA/miRNA/mRNA axis revealed new pathogenesis and treatment strategies for pBOO.

Background: Non-smoking women with lung adenocarcinoma(NSWLA) is a significant health problem globally; the carcinogenesis and prognostic signature remain poorly understood. Circular RNAs (circRNAs) are gradually implicated in cancer formation through sponging miRNAs to regulate mRNAs.
Methods: Tumor and paracancerous specimens from non-smoking women after lung adenocarcinoma surgery were collected for high-throughput sequencing of circRNA.

Coxsackievirus B5 (CVB5) is a major pathogen responsible for hand-foot-mouth disease, herpangina, and even severe death. The mechanisms underlying CVB5-induced diseases are not fully elucidated, and no specific antiviral treatments are currently available. Circular RNAs (circRNAs), a closed-loop molecular structure, have been reported to be involved in virus infectious diseases.

Background: Sorafenib, an orally active potent tyrosine kinase inhibitor (TKI), represented a primary treatment in patients with advanced hepatocellular carcinoma (HCC). Unfortunately, sorafenib resistance was regarded as a huge obstacle for HCC treatment.
Methods: RNA-sequencing including circRNA Sequencing (circRNA-Seq) for circular RNAs (circRNAs), miRNA Sequencing (miRNA-Seq) for microRNAs (miRNAs), as well as mRNA Sequencing (mRNA-Seq) for mRNAs in , were performed.

Background: Osteosarcoma, as the most common primary malignant bone tumor, has become one of the main causes of cancer-related deaths in adolescents and children. This study thus proposes new biomarkers for OS based on whole-transcriptome re-analysis and experimental confirmation.
Methods: We find two circRNA dataset related to OS, from tissue and cell perspectives respectively, from the GEO database.

Article Synopsis
- Hepatocellular carcinoma (HCC) is a serious cancer where noncoding RNAs (like circRNAs and miRNAs) play a role in its progression; researchers constructed a circRNA-miRNA-mRNA network to explore these connections.
- They identified six circRNAs associated with HCC, linking these to various miRNAs and mRNAs, and focused on the hsa_circ_0001726/miR-140-3p/KRAS axis, revealing its involvement in HCC cell growth and survival.
- The findings suggest that this network enhances understanding of HCC's underlying mechanisms and highlights the hsa_circ_0001726 axis as a potential target related to treatment resistance.
