Some of these receptors have been shown to regulate normal and CRC cell proliferation, such as α7β1 and the 67 kDa laminin receptor 67LR [8,9,10]; intestinal cell adhesion and migration, such as 67LR [8,10,11,12]; or cell differentiation, such as α6Bβ4, while α6Aβ4 has been identified as a pro-proliferative integrin in colorectal cancer cells [6]. This evidence concerns the gene RPSA and colorectal cancer.
