Fn14•Trail Effectively Inhibits Hepatocellular Carcinoma Growth
Figure 5
Fn14•TRAIL is more potent than soluble forms of Trail and Fn14 alone or in combination.
(A) SK-HEP-1 [A, left panel], HepG2 [A, middle panel] and Huh7 [A, right panel] HCC cell lines, as well as NKNT3 [B, left panel] and FHB [B, right panel] hepatocyte cell lines, were incubated with 0, 3, 30 or 300 ng/ml of Fn14•TRAIL, TRAIL, Fn14-Fc or combination of the later two for 48 hours. Viable cells were stained with trypan blue and counted. The results represent the mean +/- SD of three independent experiments (* p ≤ 0.05). (B) HepG2 HCC cells were incubated with 30ng/ml Fn14•TRAIL for 24 hours, in the presence or absence of anti Fn14 or anti TRAIL blocking antibodies. Treated cells were stained by Annexin V-FITC and Propidium Iodide, and counted by flow cytometer (2x104 cells per sample). The results represent the mean +/- SD of two independent experiments (* p ≤ 0.05).
