APC Annexin V flow cytometry of HUVEC (Figure 5) and HT1080 (Figure 6) or M21 (Figure 7) tumor cells showed a doxorubicin-induced dose- and time-dependent PS externalization to their outer surface (HUVEC, Figure 5A, 5B; HT1080, Figure 6B; M21, Figure 7B). The gene discussed is ANXA5; the disease is neoplasm.
