Abstract
N6-methyladenosine (m6A), 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 m6A 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 m6A 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 m6A 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 m6A modification.
