Figure S1.In vitro and in vivo expression of (p)HER2, (p)STAT3 and (p)ERK1/2 in 6 HNSCC lines. Cell lines were both cultured as cell lines (in vitro) and grown as xenograft tumors (in vivo) and expression levels were determined with western blot. A) In vitro expression of (p)HER2, (p)STAT2 and (p)ERK1/2. B) In vivo expression of (p)HER2, (p)STAT2 and (p)ERK1/2. Number of harvested tumors ranged from 2 to 4 per cell line.
