Definition: Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.
Input: Hepatocyte growth factor/scatter factor (HGF/SF) can sufficiently and independently induce pathophysiological angiogenesis. However, the treatment strategies have mostly been unsuccessful. The present study is the first to evaluate the possible targeting of downstream signals for the inhibition of HGF/SF-induced angiogenesis.', 'In a multichannel scratch assay with human endothelial cells (ECs), HGF/SF induced a strong and prolonged activation of MAPK and cell proliferation that was inhibited by PD98059 and LY294002/wortmannin, selective inhibitors of MAPK and PI3K signaling modules, respectively. Western blotting demonstrated a temporal relation between the activation of the two pathways. Chemical inhibition of the PI3K and MAPK signals inhibited HGF/SF-induced chemoinvasion of ECs in vitro and blocked the HGF/SF-induced neovascularization into a polymer scaffold in vivo, as quantified by vessel counts and the clearance of radioactive 133Xe.
