Abstract:

Content of body fat in domestic livestocks and poultry determines the meat quality.Adipocyte differentiation is a complex biological process regulated by many factors.Understanding the adipose differentiation-related signaling pathways and their miRNA regulations can reveal the molecular mechanisms of adipocyte differentiation.Based on introduction to the 6 important signaling pathways regulating adipocyte differentiation,biological functions and mechanisms of 8 miRNAs for promoting and another 8 miRNAs for inhibiting adipocyte differentiation were discussed.The function of target genes of these miRNAs in adipogenesis was summarized.Studies on the related miRNAs and their target genes provide theoretical bases for genetic improvement of meat quality traits in domestic livestocks and poultry.
