[PMID: 38274664 PMCID: PMC10808162 DOI: 10.3389/fvets.2023.1334434] [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: 11/07/2023] [Accepted: 12/27/2023] [Indexed: 01/27/2024] Open
Abstract
Copy number variations (CNVs) have garnered increasing attention within the realm of genetics due to their prevalence in human, animal, and plant genomes. These structural genetic variations have demonstrated associations with a broad spectrum of phenotypic diversity, economic traits, environmental adaptations, epidemics, and other essential aspects of both plants and animals. Furthermore, CNVs exhibit extensive sequence variability and encompass a wide array of genomes. The advancement and maturity of microarray and sequencing technologies have catalyzed a surge in research endeavors pertaining to CNVs. This is particularly prominent in the context of livestock breeding, where molecular markers have gained prominence as a valuable tool in comparison to traditional breeding methods. In light of these developments, a contemporary and comprehensive review of existing studies on CNVs becomes imperative. This review serves the purpose of providing a brief elucidation of the fundamental concepts underlying CNVs, their mutational mechanisms, and the diverse array of detection methods employed to identify these structural variations within genomes. Furthermore, it seeks to systematically analyze the recent advancements and findings within the field of CNV research, specifically within the genomes of herbivorous livestock species, including cattle, sheep, horses, and donkeys. The review also highlighted the role of CNVs in shaping various phenotypic traits including growth traits, reproductive traits, pigmentation and disease resistance etc., in herbivorous livestock. The main goal of this review is to furnish readers with an up-to-date compilation of knowledge regarding CNVs in herbivorous livestock genomes. By integrating the latest research findings and insights, it is anticipated that this review will not only offer pertinent information but also stimulate future investigations into the realm of CNVs in livestock. In doing so, it endeavors to contribute to the enhancement of breeding strategies, genomic selection, and the overall improvement of herbivorous livestock production and resistance to diseases.

Wang Y, Zhong Z, Munawar N, Wang R, Zan L, Zhu J. Production of green-natural and "authentic" cultured meat based on proanthocyanidins-dialdehyde chitosan-collagen ternary hybrid edible scaffolds. Food Res Int 2024; 175:113757. [PMID: 38129054 DOI: 10.1016/j.foodres.2023.113757] [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: 08/29/2023] [Revised: 11/06/2023] [Accepted: 11/22/2023] [Indexed: 12/23/2023]
Abstract
Cultured meat has the potential to fulfill the meat demand for the growing human population, but cultured meat development will be required to simplify the production process and produce naturally cultured meat, such as no longer stripping off scaffolders and adding artificial dyes. In this study, proanthocyanidins (PC) and dialdehyde chitosan (DAC) were employed as dual crosslinkers with collagen to prepare a hybrid 3D edible scaffold for the production of high-quality cell-cultured meat. The results revealed that the scaffold was biocompatible and could offer robust mechanical support and adhesion sites for bovine myoblasts, enabling long-term cell culture. Meanwhile, the Col-PC-DAC scaffold promoted the myogenic differentiation of bovine myoblasts and extracellular matrix protein secretion, further affecting the texture of cultured meat. After cooking the cultured meat and beef, it was shown that the cultured meat had some similarities to beef in color and flavor. Importantly, our findings demonstrate that cultured meat can acquire a color remarkably similar to that of conventional beef without the need for artificial dyeing. This breakthrough not only simplifies the production process but also ensures a more natural and appealing appearance of cultured meat. In conclusion, the proanthocyanidins-dialdehyde chitosan-collagen hybrid 3D edible scaffolds provide a new option for producing cultured meat that satisfies consumer expectations.

[PMID: 37657690 DOI: 10.1016/j.gene.2023.147750] [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: 05/04/2023] [Revised: 08/11/2023] [Accepted: 08/29/2023] [Indexed: 09/03/2023]
Abstract
OBJECTIVE The Janus kinase/signal transducer and transporter activator (JAK/STAT) signaling pathway plays crucial roles in lipid metabolism, glucose metabolism and cell senescence, suggesting that they are potential candidate genes affecting growth traits in animals. The present study aimed to evaluate the association between InDels in the JAK/STAT pathway and growth traits of four Chinese sheep breeds, including Tong sheep, Hu sheep, Small-tailed Han sheep and Lanzhou fat-tailed sheep. RESULTS Seventy-six indel loci of 11 genes in JAK/STAT were detected, and three genotypes were selected at four loci by PCR amplification, electrophoresis and sequencing, including one locus in STAT3, one locus in STAT5A, and two loci in JAK1. The Correlation analysis indicated that there was no significant correlation between STAT3 and growth traits in four sheep breeds (P > 0.05); STAT5A was significantly associated with body height, rump width and tube circumference in Hu sheep and body length in Tong sheep (P < 0.05); JAK1 was significantly correlated with body height, body oblique length, cross height and tube circumference in Hu sheep (P < 0.05) and body oblique length, cross height and tube circumference in small-tailed Han sheep (P < 0.05). CONCLUSION Overall, our results indicated a potential association between the growth traits of sheep and the InDels of JAK1 and STAT5A.
