Disease relevance of BAI1

  • We hypothesized that the BAI family might have anti-tumoral properties and studied the expression of BAI1 protein in normal human brain and in glioblastoma multiforme [1].
  • BAI1 expression was significantly reduced in colorectal cancers as compared to the extraneoplastic tissues (X(2) test, p=0.041) [2].
  • BAI1 expression was inversely correlated with vascular invasion and metastasis (Fisher's exact test, p 0.045) [2].
  • Taken together, these data strongly indicate that BAI1 may be an excellent gene therapy candidate for the treatment of brain tumors, especially human glioblastomas [3].
  • It is suggested that the extent of BAI1 and TIMP-2 expression in the gastric mucosa may be an important prognostic factor for predicting survival in gastric cancer [4].

Biological context of BAI1

 

Anatomical context of BAI1

 

Associations of BAI1 with chemical compounds

  • Cloning and characterization of BAP3 (BAI-associated protein 3), a C2 domain-containing protein that interacts with BAI1 [13].
 

Physical interactions of BAI1

 

Regulatory relationships of BAI1

  • However, in spite of similar tissue specificity among the three BAI genes, only BAI1 is transcriptionally regulated by p53 [14].
 

Other interactions of BAI1

  • Using a two-hybrid system, we isolated a cDNA that encodes a protein, named BAP1 (BAI1-associated protein), which interacts with the cytoplasmic region of BAI1 [8].
  • Glioblastomas with no BAI-1 and high VEGF mRNA expression are more often associated with poor clinical outcome [15].
