Figure. 5. LPA2 and LPA3 induce KLF5 expression.
HCT116 cells were treated with siRNA specific for LPA2, LPA3, or both. As a control, cells were transfected with control siRNA. Cells were then treated with LPA and phosphorylation of ERK1/2 (A) and the expression level of KLF5 (B) was determined by Western blot. Representatives of three separate experiments are shown.
