ABSTRACT
OBJECTIVE@#To observe the effects of tripterine on adhesion molecules and cell biological characteristics in mice with acute promyelocytic leukemia (APL) tumor.@*METHODS@#Eighteen SCID beige mice were caudal vein injected with NB4 cell lines (5×10@*RESULTS@#The neutrophil decrased and promyelocytes, NB4 cells, B lymphocytes and white blood cells increased in tumor-bearing group as compared with control group (P<0.05), and the expressions of serum P-selectin (P-selectin), soluble vascular adhesion molecule-1 (soluble vascular adhesion molecule-1, sVCAM-1) and soluble intercellular adhesion molecule-1 (soluble intercellular adhesion molecule-1, sICAM-1) all increased (P<0.05). The cell cycle showed that the proportion of G@*CONCLUSION@#Tripterine may not only inhibit the expression of sVCAM-1 and sICAM-1 proteins in APL tumor-bearing mice and reduce the adhesion of tumor cells, but also block tumor cells at G
