Abstract

The intramuscular fat content plays a crucial role in meat quality traits. Increasing the degree of adipogenesis in beef cattle leads to an increase in the content of intramuscular fat. Adipogenesis a complex biochemical process which is under firm genetic control. Over the last three decades, the Qinchuan beef cattle have been extensively studied for the improvement of meat production and quality traits. In this study, we reviewed the literature regarding adipogenesis and intramuscular fat deposition. Then, we summarized the research conducted on the transcriptional regulation of key adipogenic marker genes, and also reviewed the roles of adipogenic marker genes in adipogenesis of Qinchuan beef cattle. This review will elaborate our understanding regarding transcriptional regulation which is a vital physiological process regulated by a cascade of transcription factors (TFs), key target marker genes, and regulatory proteins. This synergistic action of TFs and target genes ensures the accurate and diverse transmission of the genetic information for the accomplishment of central physiological processes. This information will provide an insight into the transcriptional regulation of the adipogenic marker genes and its role in bovine adipogenesis for the breed improvement programs especially for the trait of intramuscular fat deposition.

成脂标记基因转录调控对秦川肉牛肌内脂肪改善的影响

摘要

肌内脂肪含量在肉质性状中起着至关重要的作用。增加肉牛的脂肪生成程度会导致肌肉内脂肪含量的增加。脂肪生成是一个复杂的生化过程,受严格的遗传控制。在过去的三十年里,秦川肉牛已被广泛研究以改善肉类产量和品质性状。在这项研究中,我们回顾了有关脂肪生成和肌内脂肪沉积的文献。然后,我们总结了成脂关键标记基因转录调控的研究,并回顾了成脂标记基因在秦川肉牛脂肪形成中的作用。这篇综述将详细阐述我们对转录调控的理解,转录调控是一个重要的生理过程,由一系列转录因子 (TF)、关键靶标基因和调控蛋白调控。TFs 和靶基因的这种协同作用确保了遗传信息的准确和多样化传输,以完成中枢生理过程。该信息将深入了解脂肪形成标记基因的转录调控及其在牛脂肪形成中的作用,以用于品种改良计划,尤其是肌肉内脂肪沉积的特征。TFs 和靶基因的这种协同作用确保了遗传信息的准确和多样化传输,以完成中枢生理过程。该信息将深入了解脂肪形成标记基因的转录调控及其在牛脂肪形成中的作用,以用于品种改良计划,尤其是肌肉内脂肪沉积的特征。TFs 和靶基因的这种协同作用确保了遗传信息的准确和多样化传输,以完成中枢生理过程。该信息将深入了解脂肪形成标记基因的转录调控及其在牛脂肪形成中的作用,以用于品种改良计划,尤其是肌肉内脂肪沉积的特征。
