(A) Cells were placed in Transwell upper chambers and chemotaxis was assessed with or without exposure to 10ng/ml MCP-1, the KO cells showed significantly reduced migration to MCP-1. (B) Cells were treated with 10μg/ml DiI-Ac-LDL for 4h and uptake was assessed. Representative fluorescence images showed no difference between Ctrl and KO cells. DAPI staining was used as a control. (C) Cells were treated with or without 50μg/ml ox-LDL for 24h, real-time RT-PCR showed no difference between Ctrl and KO cells for CD36, ABCA1 and ABCG1 expression. (2-way ANOVA with Tukey’s multiple comparisons test, n=3, * p<0.05, ** p<0.01, ns, no statistical difference)
