Therefore, we next determined expression levels of the following cytokines capable to promote angiogenesis in cDNA prepared from tumor tissues treated with sunitinib and/or ASA by qRT-PCR: transforming growth factor beta (TGFβ), fibroblast growth factor 1 (FGF1), basic fibroblast growth factor (FGF2), interleukin 6 (IL-6) and hepatocyte growth factor (HGF) [36-38]. The gene discussed is TGFB1; the disease is neoplasm.
