Wnt signaling, one of the key cascades regulating development and stemness, has been tightly associated with cancer, abnormalities and degenerative diseases[3]. IWP-2 is an inhibitor of Wnt pathway with IC50 of 27 nM, and it targets the O-acyltransferase Porcupine without inducing Porcupine destruction or mislocalization[4]. The anti-proliferative effect of LEF was significantly enhanced by co-incubating with 20 μM IWP-2 for 48 hours in Caki-2 cells. And the combination of LEF and IWP-2 could minimize the expression of β-catenin, c-Myc, Cyclin D1, Bcl2 and Bax to the largest extent compared with single agents[5]. Treatment with IWP-2 on the dose of 20 μM for 24 hours can decreased the viability of NP cells by decreasing the expression of cleaved caspases 3, 8, 9, and Bax and increasing the expression of Bcl-2[6]. To evaluate the efficacy of IWP-2 In vivo, 200 μl each of IWP-2-liposome or free liposome was separately injected into C57BL/6 mice intraperitoneally about 2 h before injection of a similar volume of either blue-dye-filled latex beads or E. coli DH5α. IWP-2 caused significant reduction in the uptake of blue beads as well as E. coli as assessed by CFUs in peritoneal lavage cells within 2 hours. Additionaly, the levels of TNF-α and IL-6 in the lavage fluid of the corresponding mice were reduced by 2–4-fold compared with control values[7].
