Abstract: To study the regulation of upstream regulatory region polymorphisms on BoLA- DRB3 gene expres- sion,PCR- SSCP and DNA sequencing were used to identify the linkage relationship between BoLA- DRB3* exon2 and BoLA- DRB3 URR.Combined with the predicted results of binding mode between different URR and transcrip- tion factor,three linkage types were selected to detect the BoLA-DRB3 mRNA levels by relative Real- time PCR ex- periments. The results showed that the expression abundances of BoLA-DRB3 varied in different linkage types.The expression level of mRNA of BoLA- DRB3 gene linked with H17H17 was significant higher than H1H1 and H5H6 (P<0.01).This preliminary proved that the polymorphism of upstream regulatory region can cause the expression change of BoLA- DRB3 structural gene.
