Expression and Analysis of Microtus fortis Against Schistosoma japonicum CD72

The total RNA was extracted from Microtus fortis liver tissue which before being infected and after being infected 10 d and 15 d by the Schistosoma japonicum cercariae. Using rattus norvegicus CD72 gene probes were used to hybridize analysis of CD72 difference expression in the Microtus fortis liver tissues which were infected with Schistosoma japonicum before and after being infected. At the same time, the cDNA sequence and encoded amino acid sequence of the rattus norvegicus CD72 gene and CD72 protein structural domains were analyzed by using bioinformatics. The results showed that the CD72 expression levels in the liver tissue of Microtus fortis after being infected was significantly higher than before being infected. The rattus norvegicus CD72 cDNA sequence of a total length is 1479 bp and encode 364 amino acid residues and rattus norvegicus CD72 protein containing a CD72 superfamily domain.
