[PMID: 39045457 PMCID: PMC11263028 DOI: 10.3389/fcell.2024.1391717] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Accepted: 06/19/2024] [Indexed: 07/25/2024] Open
Abstract
Circular RNAs (circRNAs) are a class of non-coding RNAs (ncRNAs) that can participate in biological processes such as gene expression, growth, and development. However, little has been explored about the function of circRNAs in the development of Apis cerana larval guts. By using our previously gained deep sequencing data from the guts of A. cerana worker larvae at 4-, 5-, and 6-day-old (Ac4, Ac5, and Ac6 groups), the expression pattern and regulatory role of circular RNAs (circRNAs) during the development process was comprehensively investigated, with a focus on differentially expressed circRNAs (DEcircRNAs) relevant to immunity pathways and developmental signaling pathways, followed by validation of the binding relationships among a key competing endogenous RNA (ceRNA) axis. Here, 224 (158) DEcircRNAs were detected in the Ac4 vs. Ac5 (Ac5 vs. Ac6) comparison group. It's suggested that 172 (123) parental genes of DEcircRNAs were involved in 26 (20) GO terms such as developmental process and metabolic process and 138 (136) KEGG pathways like Hippo and Wnt signaling pathways. Additionally, ceRNA network analysis indicated that 21 (11) DEcircRNAs could target seven (three) DEmiRNAs, further targeting 324 (198) DEmRNAs. These DEmRNAs can be annotated to 33 (26) GO terms and 168 (200) KEGG pathways, including 12 (16) cellular and humoral immune pathways (endocytosis, lysosome, Jak-STAT, etc.) and 10 (nine) developmental signaling pathways (Hippo, mTOR, Hedgehog, etc.). Interestingly, DEcircRNAs in these two comparison groups could target the same ace-miR-6001-y, forming complex sub-networks. The results of PCR and Sanger sequencing confirmed the back-splicing sites within four randomly selected DEcircRNAs. RT-qPCR detection of these four DEcircRNAs verified the reliability of the used transcriptome data. The results of dual-luciferase reporter assay verified the binding relationships between novel_circ_001627 and ace-miR-6001-y and between ace-miR-6001-y and apterous-like. Our data demonstrated that DEcircRNAs were likely to modulate the developmental process of the A. cerana worker larval guts via regulation of parental gene transcription and ceRNA network, and novel_circ_001627/ace-miR-6001-y/apterous-like was a potential regulatory axis in the larval gut development. Findings from this work offer a basis and a candidate ceRNA axis for illustrating the circRNA-modulated mechanisms underlying the A. cerana larval guts.

Abstract
Various circular RNAs (circRNAs) are novel class of non-coding RNAs, which are pervasively transcribed in the genome. CircRNAs play important roles in human, animals and plants. Up to now, there was no report regarding circRNAs of cleft palate by 2,3,7,8-tetrachlorodibenzo-pdioxin (TCDD) induce. The present study screened identification and characterization of differential expressed-circRNAs in TCDD-induced cleft palate. 6903 circRNAs candidates came from cleft palates. Among them, 3525 circRNAs are up-regulation, and 3378 circRNAs are down-regulation by TCDD induce. The cluster and GO analysis found that circRNAs involved in biological process, cellular component, and molecular function. Through the analysis of KEGG Pathway, circRNAs made functions via classical signaling pathway in cleft palate, such as TGF-beta signaling pathway, BMP signal pathway, MAPK signaling pathway. In addition, we found down-regulated circRNA224, circRNA3302 and up-regulated circRNA5021 targeted tgfbr3, but up-regulated circRNA4451 targeted tgfbr2. circRNA4451 may make functions through TGF-beta signaling pathway. These results suggested that many different circRNAs may make important role in TCDD-induced cleft palate, which provided a theoretical basis for further research.

Huang M, Dong J, Guo H, Xiao M, Wang D. Identification of circular RNAs and corresponding regulatory networks reveals potential roles in the brains of honey bee workers exposed to dinotefuran. PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2022; 180:104994. [PMID: 34955187 DOI: 10.1016/j.pestbp.2021.104994] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Revised: 11/10/2021] [Accepted: 11/16/2021] [Indexed: 06/14/2023]
Abstract
Honey bees are important and highly efficient pollinators of agricultural crops and have been negatively affected by insecticides in recent years. Circular RNA (circRNA) plays an important role in the regulation of multiple biological and pathological processes; however, its role in the honey bee brain after exposure to dinotefuran is not well understood. Here, the expression profiles and potential modulation networks of circRNAs in the brains of workers (Apis mellifera) were comprehensively investigated using RNA sequencing and bioinformatics. In total, 33, 144, and 211 differentially expressed (DE) circRNAs were identified on the 1st, 5th and 10th days after exposure to dinotefuran, respectively. Enrichment analyses revealed that the host genes of DE circRNAs were enriched in the Hippo signaling pathway-fly, Wnt signaling pathway, and neuroactive ligand-receptor interaction. circ_0002266, circ_0005080, circ_0010239 and circ_0005415 were found to have translational potential due to the presence of an internal ribosome entry site (IRES). An integrated analysis of the DE circRNA-miRNA-mRNA networks suggest that circ_0008898 and circ_0001829 may participate in the immune response to dinotefuran exposure by acting as miRNA sponges. Our results provide invaluable basic data on A. mellifera brain circRNA patterns and a molecular basis for further study of the biological function of circRNAs in the development and immune response of honey bees.
