IκB inhibits the enhancement of MMP9 expression by LMP1. (a) Gelatin zymography. Samples of C33A cells were prepared as described in Materials and Methods. (b) CAT assays. The effector plasmids were cotransfected with −670 CAT (full-length MMP9 promoter construct). The mean values and SDs represented were obtained from three experiments.
