ADGRB1（adhesion G protein-coupled receptor B1），癌症关联基因，基因ID：575，血管生成是由新血管生长的刺激剂和抑制剂之间的局部平衡控制的，并且在正常生理条件下被抑制血管生成对实体瘤的生长和转移至关重要为了获得生长所需的血液供应，肿瘤细胞在诱导因子分泌增加和内源性负调节因子产生减少的情况下，具有很强的血管生成和吸引新血管的能力bai1在内含子中至少包含一个“功能性”p53结合位点，其表达被证明是由野生型p53诱导的。另有两个脑血管生成抑制基因bai2和bai3与bai1具有相似的组织特异性和结构，但只有bai1受p53的转录调控。bai1被认为是分泌素受体家族的成员，是血管生成的抑制剂和胶质母细胞瘤的生长抑制物[由refseq提供，2008年7月]Angiogenesis is controlled by a local balance between stimulators and inhibitors of new vessel growth and is suppressed under normal physiologic conditions. Angiogenesis has been shown to be essential for growth and metastasis of solid tumors. In order to obtain blood supply for their growth， tumor cells are potently angiogenic and attract new vessels as results of increased secretion of inducers and decreased production of endogenous negative regulators. BAI1 contains at least one 'functional' p53-binding site within an intron， and its expression has been shown to be induced by wildtype p53。
