Sorafenib decreases the mRNA expression of VLAs in vivo. B16BL6 cells were inoculated into the right hind footpad of mice, and treated with sorafenib (10, 30 and 50 mg/kg). After 21 days, the mice were sacrificed, and the right footpads were harvested. The mRNA expression levels of (A) VLA-1, (B) VLA-2, (C) VLA-3, (D) VLA-4, (E) VLA-5 and (F) VLA-6 were measured using reverse transcription-quantitative PCR. Data are presented as the mean ± SD of three independent experiments. *P<0.05 vs. control. VLA, very late antigen.
