The significant increase in PCA shown between "0 μM" and "IDR" without anti-TF/annexin V becomes almost a non-significant difference in the presence of anti-TF/annexin V. In AML cell lines under non-stimulated conditions by IDR, PCA was clearly decreased after blocking by the anti-TF antibody compared with the unblocked state. The gene discussed is TF; the disease is acute myeloid leukemia.
