In the current research, CNP rat models were established through the intraprostatic injection of carrageenan into the prostate. Then, next?generation sequencing was performed to explore the miRNA expression profile in CNP. Gene Ontology (GO) and Kyoto En cyclopedia of Genes and Geno mes (KEGG) bioinformatical an a lyses were conducted to reveal the enriched biological processes, molecular functions, and cellular components and signaling pathways. As a result, 1224, 1039, and 1029 known miRNAs were annotated in prostate tissues from the blank control (BC), normal saline injection (NS), and carrageenan injection (CAR) groups (n = 3 for each group), respectively. Among them, 84 miRNAs (CAR vs BC) and 70 miRNAs (CAR vs NS) with significantly different expression levels were identified. Compared with previously reported miRNAs with altered expression in various inflammatory diseases, the majority of deregulated miRNAs in CNP, such as miR-146b-5p, miR?155-5p, miR-150-5p, and miR-139-5p, showed similar expression patter ns. Moreover, bioinformatics analyses have en riched mitoge reactivated protei n kinase (MAPK), cyclic adenosine monophosphate (cAMP), endocytosis, mammalian target of rapamycin (mTOR), and forkhead box 0 (FoxO) signaling pathways. These pathways were all invoIved in immune response, which indicates the critical regulatory role of the immune system in CNP initiati on and progression. Our inv estigatio n has presented a global view of the d iff ere ntially expressed miRNAs and potential regulatory networks containing their target genes, which may be helpful for identifying the novel mechanisms of miRNAs in immune regulation and effective target-specific theragnosis for CNP.展开更多
