[PMID: 37473519 PMCID: PMC10371811 DOI: 10.1016/j.psj.2023.102913] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 06/26/2023] [Accepted: 06/27/2023] [Indexed: 07/22/2023] Open
Abstract
Innate immunity, as an organism's first line of defense, plays a crucial role in rapidly responding to and protecting the body against invading pathogens. As a cytosolic RNA sensor for viral infections, including infections caused by influenza virus, the innate immune system in chickens has 2 major pathogen-recognition receptors (PRRs): Toll-like receptor 3 (TLR3) and melanoma differentiation-associated protein 5 (MDA5). The signaling pathways activated by PRRs are complex, systemic processes that underlie the response to foreign molecules. In this study, we investigated the interactions among MDA5, mitochondrial antiviral signaling protein (MAVS), and stimulator of interferon genes (STING) signaling in chicken cells. To exclude the effects of TLR3, we transfected the clustered regularly interspaced palindromic repeats/CRISPR-associated protein 9 (CRISPR-Cas9) expression vector and TLR3-targeted gRNA plasmid into chicken DF-1 cells. We selected TLR3-knockout (KO) cell line and sequentially, we established 2 double-KO cell lines: TLR3-MAVS KO and TLR3-STING KO. After treatment with polyinosinic:polycytidylic acid (poly(I:C)), type I interferon (IFN), IFN-stimulated gene, and antiviral gene (IFN regulatory factor 7, IFNβ, Mx1, and protein kinase R1) expression was not completely activated in TLR3-MAVS KO cells, whereas it was consistently upregulated in wild-type and TLR3-STING KO DF-1 cells. These results suggest that STING is not an intermediator between MDA5 and MAVS; moreover, it does not directly interact with MDA5 during innate immune activation in chicken DF-1 cells.

Abstract
Genetic modification enables modification of target genes or genome structure in livestock and experimental animals. These technologies have not only advanced bioscience but also improved agricultural productivity. To introduce a foreign transgene, the piggyBac transposon element/transposase system could be used for production of transgenic animals and specific target protein-expressing animal cells. In addition, the clustered regularly interspaced short palindromic repeat-CRISPR associated protein 9 (CRISPR-Cas9) system have been utilized to generate chickens with knockout of G0/G1 switch gene 2 (G0S2) and myostatin, which are related to lipid deposition and muscle growth, respectively. These experimental chickens could be the invaluable genetic resources to investigate the regulatory pathways and mechanisms of improvement of economic traits such as fat quantity and growth. The gene-edited animals could also be applicable to the livestock industry.

Genome-Wide Identification and Characterization of Long Non-Coding RNAs in Embryo Muscle of Chicken. Animals (Basel) 2022; 12:ani12101274. [PMID: 35625120 PMCID: PMC9137640 DOI: 10.3390/ani12101274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 05/03/2022] [Accepted: 05/09/2022] [Indexed: 11/16/2022] Open
Abstract
Embryonic muscle development determines the state of muscle development and muscle morphological structure size. Recent studies have found that long non-coding RNAs (lncRNAs) could influence numerous cellular processes and regulated growth and development of flora and fauna. A total of 1056 differentially expressed lncRNAs were identified by comparing the different time points during embryonic muscle development, which included 874 new lncRNAs. Here, we found that there were different gene expression patterns on the 12th day of embryo development (E12). Herein, WGCNA and correlation analyses were used to predict lncRNA function on E12 through the screening and identification of lncRNAs related to muscle development in the embryo leg muscles of Chengkou mountain chickens at different times. GO and KEGG functional enrichment analysis was performed on target genes involved in cis-regulation and trans-regulation. An interaction network diagram was constructed based on the muscle development pathways, such as Wnt, FoxO, and PI3K-AKT signaling pathways, to determine the interaction between mRNAs and lncRNAs. This study preliminarily determined the lncRNA expression pattern of muscle development during the middle and late embryonic stages of Chengkou mountain chickens, and provided a basis to analyze the molecular mechanism of muscle development.

Muscle differentiation induced by p53 signaling pathway-related genes in myostatin-knockout quail myoblasts. Mol Biol Rep 2020; 47:9531-9540. [PMID: 33225386 DOI: 10.1007/s11033-020-05935-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Accepted: 10/20/2020] [Indexed: 12/22/2022]
Abstract
The myostatin (MSTN) gene is of interest in the livestock industry because mutations in this gene are closely related to growth performance and muscle differentiation. Thus, in this study, we established MSTN knockout (KO) quail myoblasts (QM7) and investigated the regulatory pathway of the myogenic differentiation process. We used clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 to generate MSTN KO QM7 cells and subsequently isolated a single cell-derived MSTN KO QM7 subline with 10- and 16-nucleotide deletions that induced translational frameshift mutations. The differentiation capacity and proliferation rate of MSTN KO QM7 cells were enhanced. We conducted next-generation-sequencing (NGS) analysis to compare the global gene expression profiles of wild-type (WT) QM7 and MSTN KO QM7 cells. Intriguingly, NGS expression profiles showed different expression patterns of p21 and p53 in MSTN KO QM7 cells. Moreover, we identified downregulated expression patterns of leukemia inhibitory factor and DNA Damage Inducible Transcript 4, which are genes in the p53 signaling pathway. Using quantitative RT-PCR (qRT-PCR) analysis and western blotting, we concluded that p53-related genes promote the cell cycle by upregulating p21 and enhancing muscle differentiation in MSTN KO QM7 cells. These results could be applied to improve economic traits in commercial poultry by regulating MSTN-related networks.

Functional analyses of miRNA-146b-5p during myogenic proliferation and differentiation in chicken myoblasts. BMC Mol Cell Biol 2020; 21:40. [PMID: 32471354 PMCID: PMC7260857 DOI: 10.1186/s12860-020-00284-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2019] [Accepted: 05/20/2020] [Indexed: 01/19/2023] Open
Abstract
Background In the poultry and livestock industries, precise genetic information is crucial for improving economic traits. Thus, functional genomic studies help to generate faster, healthier, and more efficient animal production. Chicken myoblast cells, which are required for muscle development and regeneration, are particularly important because chicken growth is closely related to muscle mass. Results In this study, we induced expression of microRNA-146b-5p mediated by the piggyBac transposon system in primary chicken myoblast (pCM) cells. Subsequently, we analyzed and compared the proliferation and differentiation capacity and also examined the expression of related genes in regular pCM (rpCM) cells and pCM cells overexpressing miRNA-146b-5p (pCM-146b OE cells). pCM-146b OE cells showed increased proliferation and upregulated gene expression related to cell proliferation. In addition, next-generation sequencing analyses were performed to compare global gene expression patterns between rpCM cells and pCM-146b OE cells. We found that the higher proliferation in pCM-146b OE cells was the result of upregulation of gene sets related to the cell cycle. Moreover, miRNA-146b-5p overexpression had inhibitory effects on myotube differentiation in pCM cells. Conclusions Collectively these results demonstrate that miR-146b-5p is closely related to the proliferation and differentiation of chicken myogenic cells as a modulator of post-transcription.

Abstract
FOXO3 belongs to the Forkhead O transcription factor family and it is an important gene in multiple biological processes, such as cell cycle control, cell proliferation, cell apoptosis, human longevity, and oxidative stress. Previous studies have shown that FOXO3 is associated with skeletal muscle growth and adipose development in mammals. However, the sequence of chicken FOXO3 is still incomplete and the cellular functions of FOXO3 in chickens are poorly understood. Thus, we obtained the full-length sequence of chicken FOXO3 by 5' rapid amplification of cDNA ends (5' RACE) and the phylogenetic tree showed that the chicken FOXO3 sequence was homologous with those in other species. Flow cytometry analysis and 5-ethynyl-2'-deoxyuridine assays showed that FOXO3 repressed cellular proliferation and induced apoptosis in a chicken hepatocellular carcinoma cell line (LMH). Mutations were screened in the second exon of FOXO3 and 13 synonymous single nucleotide polymorphisms were found in the test population. Further analysis showed that rs317670452 and rs15379317 were associated with many growth and carcass traits, such as the body weight at different ages and breast muscle weight. Our results indicate that chicken FOXO3 has similar cellular functions to those found in mammals and it is significantly associated with chicken growth.

Circular RNA circ-FoxO3 Inhibits Myoblast Cells Differentiation. Cells 2019; 8:cells8060616. [PMID: 31248210 PMCID: PMC6627427 DOI: 10.3390/cells8060616] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Revised: 06/13/2019] [Accepted: 06/17/2019] [Indexed: 02/06/2023] Open
Abstract
CircRNA is a type of closed circular non-coding RNA formed by reverse splicing and plays an important role in regulating the growth and development of plants and animals. To investigate the function of circ-FoxO3 in mouse myoblast cells' (C2C12) differentiation and proliferation, we used RT-qPCR to detect the expression level of circ-FoxO3 in mouse myoblast cells at different densities and different differentiation stages, and the specific interference fragment was used to inhibit the expression level of circ-FoxO3 in myoblast cells to observe its effect on myoblast cells proliferation and differentiation. We found that the expression level of circ-FoxO3 in myoblast cells increased with the prolongation of myoblast cells differentiation time, and its expression level decreased with the proliferation of myoblast cells. At the same time, we found that the differentiation ability of the cells was significantly increased (p < 0.05), but the cell proliferation was unchanged (p > 0.05) after inhibiting the expression of circ-FoxO3 in myoblast cells. Combining the results of bioinformatics analysis and the dual luciferase reporter experiment, we found that circ-FoxO3 is a sponge of miR-138-5p, which regulates muscle differentiation. Our study shows that circ-FoxO3 can inhibit the differentiation of C2C12 myoblast cells and lay a scientific foundation for further study of skeletal muscle development at circRNA levels.
