Intramuscular fat (IMF) content is a critical factor affecting meat flavor, juiciness, tenderness, and color. Therefore, the improvement of IMF content is one of the hotspots of animal science research. Fat deposition is the result of a combination of increased number of fat cells and cellular hypertrophy. In addition, transcription factors can influence the number of adipocytes and regulate lipid metabolism. The progress of the transcription factors regulating adipocyte differentiation in beef cattle, including IMF cell sources, and promoting or inhibiting adipogenic differentiation of transcription factors is reviewed in this paper.
肌内脂肪(IMF)含量是影响肉风味、多汁性、嫩度和颜色的关键因素。因此,提高 IMF 含量是动物科学研究的热点之一。脂肪沉积是脂肪细胞数量增加和细胞肥大的结果。此外,转录因子可以影响脂肪细胞的数量并调节脂质代谢。本文综述了调节肉牛脂肪细胞分化的转录因子的研究进展,包括 IMF 细胞来源、促进或抑制脂肪生成分化的转录因子。
