1 Effect of all-trans retinoic acid and arsenic trioxide on tissue factor expression in acute promyelocytic leukemia cells. Arsenic Trioxide coagulation factor III, tissue factor Homo sapiens
2 OBJECTIVE: To study the effect of all-trans retinoic acid (ATRA) and arsenic troxide (As2O3) on tissue factor (TF) expression and procoagulant activity (PCA) of acute promyelocytic leukemia (APL) cells in vivo and in vitro. Arsenic Trioxide coagulation factor III, tissue factor Homo sapiens
3 OBJECTIVE: To study the effect of all-trans retinoic acid (ATRA) and arsenic troxide (As2O3) on tissue factor (TF) expression and procoagulant activity (PCA) of acute promyelocytic leukemia (APL) cells in vivo and in vitro. Arsenic Trioxide coagulation factor III, tissue factor Homo sapiens
4 RESULTS: Both ATRA and As2O3 can down-regulate the TF antigen, its mRNA transcription and membrane PCA of APL cells in vivo and in vitro, in a time-dependent manner. Arsenic Trioxide coagulation factor III, tissue factor Homo sapiens
5 Both ATRA and As2O3 can also down-regulate the TF antigen in U937 cells transfected with or without PML-RARa. Arsenic Trioxide coagulation factor III, tissue factor Homo sapiens
6 CONCLUSION: Tissue factor expression and PCA in APL cells may be down-regulated by ATRA and As2O3. Arsenic Trioxide coagulation factor III, tissue factor Homo sapiens
7 By down-regulating TF expression, As2O3 might also be used to improve the DIC-related hemorrhage in APL. Arsenic Trioxide coagulation factor III, tissue factor Homo sapiens
8 The down-regulating effect of ATRA and As2O3 on TF expression in U937 cells might not involve this fusion protein. Arsenic Trioxide coagulation factor III, tissue factor Homo sapiens
