Transcription factors regulate adipocyte differentiation in beef cattle.

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.
