Abstract:
Objective To dynamically observe the plasma levels of MFG-E8 in mice with obstructive jaundice and the expression of MFG-E8 mRNA and protein in liver,spleen,lymph nodes and thymus,and to investigate their significance in obstructive jaun-dice.Methods The mice models of obstructive jaundice were established and divided into the sham operation group and the common bile duct ligation group.Western blot was adopted to detect plasma MFG-E8 protein expression in obstructive jaundice mice on 3,7, 14 d;the MFG-E8 mRNA expression changes in liver,spleen,lymph nodes and thymus tissue were detected by RT-PCR;the MFG-E8 protein expression in the above organizations was detected by Western blot.Results Plasma MFG-E8 protein levels at each time point in the obstructive jaundice mice were significantly lower than those in the control group (P<0.05);MFG-E8 mRNA expres-sion in liver,spleen,lymph nodes and thymus tissue was significantly decreased (P<0.05),meanwhile the MFG-E8 protein levels in liver,spleen,lymph nodes and thymus tissue were significantly decreased (P<0.05).Conclusion the expression of MFG-E8 in obstructive jaundice immune tissue is significantly decreased,which may have a significant impact on the clearance of apoptotic cells in obstructive jaundice.
