NSC-127102 inhibits IL-8 and VCAM-1 gene expression. (A) HepG2 cells were treated for 24 h with 100 or 300 μM NSC-127102. Cells were also treated with 20 μM U0126 for 24 h. Cells were subsequently harvested and total RNA isolated. The effects of NSC-127102 on IL-8 and VCAM-1 mRNA levels were assessed by RT-PCR. Cyclophilin mRNA served as a loading control. (B) HepG2 cells were treated with 30 ng/ml TNF-α for 4 h to stimulate IL-8 gene expression in the presence or absence of 100 or 300 μM NSC-127102. Total RNA was isolated and IL-8 mRNA levels were assessed by RT-PCR.
