Amino acid residues required for binding of vascular cell adhesion molecule-1 to integrin alpha 4 beta 7.

The homologous Ig-like domains 1 and 4 of vascular cell adhesion molecule (VCAM)-1 present binding sites to the leukocyte integrins alpha 4 beta 1 and alpha 4 beta 7 . In the present study, amino acid substitution mutants were used to identify sequence motifs mediating binding of integrin alpha 4 beta 7 to the first domain of VCAM-1. We demonstrate that binding of integrin alpha...

Reduced expression of a gene proliferation signature is associated with enhanced malignancy in colon cancer

The association between cell proliferation and the malignant potential of colon cancer is not well understood. Here, we evaluated this association using a colon-specific gene proliferation signature (GPS). The GPS was derived by combining gene expression data obtained from the analysis of a cancer cell line model and a published colon crypt profile. The GPS was overexpressed in...
