Abstract:

The aim of this experiment was to investigate the biological function of BMF gene(Bcl-2 modifying factor)in the follicular development of Small-tailed Han Sheep,and to provide the theoretical basis for further exploration of its regulatory mechanism in the future.Firstly,the synchronization estrus was implemented in Small-tailed Han Sheep.Then,we used Quantitative Real-time PCR(RT-qPCR),Western Blot(WB)and Immunofluorescence staining(IF)to detect the expression of the BMF gene and its encoded protein in the ovaries at different physiological stages;subsequently,we isolated follicles of different diameters and analyzed the differences in expression of the target gene in large,middle and small follicles.The results showed that the expression of BMF mRNA was significantly higher in the ovary at 42 h after thrombectomy than at 18 h after thrombectomy(P<0.05),and the results of its encoded protein expression of BMF were basically consistent with the mRNA.BMF protein was mainly expressed in follicular granulosa cells and follicular membrane cells.We further isolated follicles and found that the expression of both the BMF gene and its encoded protein in middle follicles was significantly higher than that in large and small follicles(P<0.05).These results suggest that BMF gene may be involved in the ovarian cyclic activity and play an important role in follicular development.
