N6-methyladenosine (m 6 A), the most abundant internal mRNA modification in eukaryotes, plays a vital role in regulating adipogenesis. However, its underlying mechanism remains largely unknown. Our previous study found that ADRB1 gene has m 6 A modification in both muscle and fat tissue. In this study, we interfered with FTO and ADRB1 genes After we cultured rabbit preadipocytes respectively. Oil red O staining and triglyceride assay were used to detect adipocyte differentiation. RT-qPCR was used to detect gene expression level and MeRIP-qPCR was used to detect the m 6 A modification level of gene. The results showed that FTO promoted the differentiation of adipocytes. At the same time, FTO up regulated the expression of ADRB1 gene and down regulated the m 6 A modification level of ADRB1 gene. Finally, we found that ADRB1 inhibited adipocyte differentiation. Together, we showed that FTO promoted adipocyte differentiation by regulating ADRB1 gene through m 6 A modification. |
