Abstract
The NOTCH signaling pathway plays a pivotal role in diverse developmental processes, including cell proliferation and differentiation. In this study, we investigated whether this signaling molecules also contribute to avian adipogenesis. Using previous mRNA-seq datasets, we examined the expression of 11 signaling members during avian adipocyte differentiation. We found most members are down-regulated throughout differentiation (p < 0.05). As a representative, NOTCH1 was decreased in cultured chicken abdominal adipocytes during adipogenesis at mRNA and protein levels (p < 0.05). Moreover, using an overexpression plasmid for NOTCH1's intracellular domain (NICD1), as well as siRNA and DAPT to activate or deplete NOTCH1 in cells, we investigated the role of NOTCH1 in avian adipogenesis. Our findings illuminate that NOTCH1 activates the expression of HES1 and SOCS3 while it decreases NR2F2 and NUMB (p < 0.05), as well as inhibits oleic acid-induced adipocyte differentiation (p < 0.01). We further demonstrate that HES1, a downstream transcription factor activated by NOTCH1, also significantly inhibits adipogenesis by suppressing PPARγ and C/EBPα (p < 0.01). Collectively, these findings establish NOTCH1 as a negative regulator of avian adipocyte differentiation, unveiling NOTCH signaling as a potential target for regulating avian fat deposition.

[PMID: 38181918 DOI: 10.1016/j.ijbiomac.2023.129144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Revised: 12/10/2023] [Accepted: 12/28/2023] [Indexed: 01/07/2024]
Abstract
TMEM182, a transmembrane protein highly expressed in muscle and adipose tissues, plays a crucial role in muscle cell differentiation, metabolism, and signaling. However, its role in fat deposition and metabolism is still unknown. In this study, we used overexpression and knockout models to examine the impact of TMEM182 on fat synthesis and metabolism. Our results showed that TMEM182 overexpression increased the expression of fat synthesis-related genes and promoted the differentiation of preadipocytes into fat cells. In TMEM182 knockout mice, there was a significant decrease in abdominal fat deposition. RNA sequencing results showed that TMEM182 overexpression in preadipocytes enhanced the activity of pathways related to fat formation, ECM-receptor interaction, and cell adhesion. Furthermore, our analysis using UPLC-MS/MS showed that TMEM182 significantly altered the metabolite and lipid content and composition in chicken breast muscle. Specifically, TMEM182 increased the content of amino acids and their derivatives in chicken breast muscle, promoting amino acid metabolic pathways. Lipidomics also revealed a significant increase in the content of glycerophospholipids, sphingolipids, and phospholipids in the breast muscle after TMEM182 overexpression. These findings suggest that TMEM182 plays a crucial role in regulating fat deposition and metabolism, making it a potential target for treating obesity-related diseases and animal breeding.

Abstract
Goat intramuscular fat (IMF) deposition is precisely regulated by many key genes as well as transcription factors. Nevertheless, the potential of the regulators of goat IMF deposition remains undefined. In this work, we reported that the transcription factor FOS is expressed at a low level at the early differentiation stage and at a high level in late differentiation. The overexpression of FOS inhibited intramuscular adipocyte lipid accumulation and significantly downregulated the expressions of PPARγ, C/EBPβ, C/EBPα, AP2, SREBP1, FASN, ACC, HSL, and ATGL. Consistently, the knockdown of FOS, facilitated by two distinct siRNAs, significantly promoted intramuscular adipocyte lipid accumulation. Moreover, our analysis revealed multiple potential binding sites for FOS on the promoters of PPARγ, C/EBPβ, and C/EBPα. The expression changes in PPARγ, C/EBPβ, and C/EBPα during intramuscular adipogenesis were opposite to that of FOS. In summary, FOS inhibits intramuscular lipogenesis in goats and potentially negatively regulates the expressions of PPARγ, C/EBPβ, and C/EBPα genes. Our research will provide valuable data for the underlying molecular mechanism of the FOS regulation network of intramuscular lipogenesis.

[PMID: 37562129 PMCID: PMC10432839 DOI: 10.1016/j.psj.2023.102970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 07/18/2023] [Accepted: 07/23/2023] [Indexed: 08/12/2023] Open
Abstract
The editing efficiency primarily hinders the utility of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) technology in poultry. For a better understanding of the factors that influence the efficiency of gene knockout mediated by CRISPR/Cas9 in chicken DF1 cells, the single or dual single guide RNA (sgRNA) targeted exon regions of genes (taking anti-Müllerian hormone, TGF-beta receptor type-2 and Peroxisome proliferator-activated receptor gamma as examples) were designed. The sgRNA-CRISPR/Cas9 vectors with corresponding reporter vectors were transfected into DF1 cells. T7 endonuclease 1 (T7E1) and amplicon sequencing assay were compared for evaluating genome editing efficiency and the indel profiles were analyzed based on the data of amplicon sequencing. Meanwhile, to evaluate the precision of Cas9 cleavage, we also analyzed the homology of small insertion with the nucleotides of upstream and downstream of cleave sties. The surrogate reporter systems showed strong enrichment function, and the indel percentages were increased after puromycin selection. The indel ratios of T7E1 assay were lower than amplicon sequencing assay, which indicated T7E1 isn't fit to be used as the sole evaluation criterion for the targeting efficiency of CRISPR/Cas9. Based on the amplicon sequencing analysis, the editing efficiency showed noticeable differences among cells treated with different sgRNAs. However, the variety of indel efficiencies was not related to the GC content of sgRNA or chromosome types of targeted genes. The results showed that the dual sgRNA might not raise the indel ratios compared with individual sgRNA, but they could increase the ratios of the fragment deletions. The present study suggested that the surrogate reporter was an effective method to promote the editing efficiencies of CRISPR/Cas9 in chicken cells. The dual sgRNA could increase the fragment deletions, and the sensitivity of amplicon sequencing to detect cleavage was higher than the T7 endonuclease 1 assay. These results are essential to improve the application of CRISPR/Cas9 technology in chicken cells.
