J Cell Physiol 2019; 234:21060-21075. [PMID: 31020657 DOI: 10.1002/jcp.28709] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2019] [Revised: 04/02/2019] [Accepted: 04/11/2019] [Indexed: 12/25/2022]
Abstract
MicroRNAs have emerged as key regulators involved in a variety of biological processes. Previous studies have demonstrated that miR-192/215 participated in progression of Crohn's disease and colorectal cancer. However, their concrete relationships and regulation networks in diseases remain unclear. Here, we used bioinformatics methods to expound miR-192/215-5p macrocontrol regulatory networks shared by two diseases. For data mining and figure generation, several miRNA prediction tools, Human miRNA tissue atlas, FunRich, miRcancer, MalaCards, STRING, GEPIA, cBioPortal, GEO databases, Pathvisio, Graphpad Prism 6 software, etc . are extensively applied. miR-192/215-5p were specially distributed in colon tissues and enriched biological pathways were closely associated with human cancers. Emerging role of miR-192/215-5p and their common pathways in Crohn's disease and colorectal cancer was also analyzed. Based on results derived from multiple approaches, we identified the biological functions of miR-192/215-5p as a tumor suppressor and link Crohn's disease and colorectal cancer by targeting triglyceride synthesis and extracellular matrix remodeling pathways.

[PMID: 30905811 DOI: 10.1016/j.gene.2019.03.044] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Revised: 03/12/2019] [Accepted: 03/20/2019] [Indexed: 01/21/2023]
Abstract
MicroRNAs (miRNAs) play an important role in animal growth and disease development, and sequence variation in microRNAs can alter their functions. Herein, we explored the effects of mutations in the miRNA-215 precursor sequence on the miRNA-215 regulatory network and resistance to Escherichia coli (E. coli). Polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) was used to detect sequence variations in Sutai and Meishan pigs. The miR-192 precursor sequence was not mutated, but the miR-215 precursor included an AT insertion mutation at position 6 (start from the first base of the miR-215 precursor) and a C/T mutation at position 43. Wild-type (WT) and mutant miR-215 precursor expression vectors were constructed to investigate the effects of sequence variation on expression of miR-215 and its target genes DLG5 and ALCAM, cytokine levels and E. coli adhesion. Compared with the WT control group, cells harbouring the C/T mutant vector displayed reduced miR-215 expression, increased target gene expression, elevated cytokine levels and rising E. coli adhesion, whereas cells harbouring the AT insertion mutant vector were not significantly changed. The sequence variation in the miRNA-215 precursor may affect the miRNA-215 regulatory network, and alter the stability of intestinal epithelial cells (IPEC-J2 cells) and resistance to E. coli. Our findings provide guidance for future research on the regulatory mechanisms of miR-215 in porcine resistance to E. coli F18, and identifying effective genetic markers against this organism.
