Knockdown of USF1 inhibited cells proliferation, migration and invasion via deregulation of the neurotrophin signaling pathway. (A) The protein expression of p75NTR, RIPK2, IRAK1, IKKβ and USF1, detected by WB in H1299 and A549 cells; (B) The levels of IRAK1 was detected by WB in H1299 and A549 cells; (C,D) Cells migration was detected by wound healing assay in H1299 and A549 cells; (E,F) Cells migration and invasion were detected by transwell assay in H1299 and A549 cells; (The sh-USF1, cells were transfected with sh-USF1; sh-USF1+pcDNA3.1, cells were transfected with sh-USF1 and pcDNA3.1; sh-USF1+ pcDNA3.1- IRAK1; *p < .05 means statistically significant difference when compared with sh-USF1+ pcDNA3.1 group).
