APOA1 and neoplasm: Compared with negative control (i.e., tumor cells treated without ApoA-1), tumor cell viability with ApoA-1 was significantly suppressed in a time-dependent manner after exposure to 25 or 50 μg/mL ApoA-1 for 7 days (0.834 ± 0.004 vs. 1.142 ± 0.042 for 5 days in MHCC97H, p<0.05;0.870 ± 0.008 vs. 1.098 ± 0.012 for 5 days in Huh7, p<0.05, Figure 3D).
