    Abstract:

    Objective To screen and determine the effective silencing targets of β2-microglobulin(B2m)gene at the cellular level in marmoset.Methods By homology comparison of the b2m gene in human and the B2m gene in marmoset, choose homology small hairpin RNA(shRNA)sequences targeting marmoset B2m gene were designed, We choose homology small hairpin RNA(shRNA)sequences targeting designed B2m gene to make homology analysis, and insert into lentivirus-based gene silencing constructs FUGW-TDT. The vectors were transfected into HEK293T cells induced by polyethylenimine(PEI). The suppression of B2m mRNA was detected by real-time PCR. Results Two gene-silencing sequences were screened that lied in 290~310 bp and 665~685 bp of the marmoset B2m mRNA, and have statistical significance in the silencing rate:(46.54±7.91)% (P< 0.05) and(83.22±4.37)%(P< 0.0001). Conclusions Two effective silencing target sequences are screened at cellular level, which can be further used in studies on gene silencing in marmoset.
